Description

The present invention relates to a modular throttle assembly for a process plant, such as a chemical plant, a power plant, a food processing plant, or the like; a controllable throttle module, in particular one insertable therein, for controlling, in particular for adjusting and/or regulating, one or more fluid profiles and/or fluid flows in the process plant; and a fixed throttle module, in particular one insertable therein, for controlling, in particular for adjusting and/or regulating, one or more fluid profiles and/or fluid flows in the process plant. Furthermore, the invention relates to a method for providing different fluid profiles, in particular fluid characteristics, of a fluid flow, in particular a process fluid flow, by means of a corresponding modular throttle assembly and/or a corresponding controllable throttle module and/or a corresponding fixed throttle module.

The printed matter WO 2021/ 071 738 A1 Figure 1 shows a valve for regulating fluid flow, comprising a housing that defines a fluid inlet and a fluid outlet. A flow control element is located within the housing and configured to dissipate energy in a fluid flowing from the fluid inlet to the fluid outlet. A valve seat is positioned within the housing and includes a plurality of vortex generators that create vortices in the fluid as it flows through the valve seat. A piston is located within the housing and is movable relative to it between a closed and an open position. The piston moves away from the valve seat as it moves from the closed position toward the open position, so that the fluid flow through the flow control element and the valve seat increases as the piston moves from the closed to the open position. The piston is designed as a cage valve. The housing is specifically designed and constructed to accommodate the piston and the flow control element, which negatively impacts flexibility and compatibility for various applications. The possible and adjustable fluid flow patterns are also limited.

Several throttle discs are made of US 10 989 329 B2 A known device for controlling fluid flow is shown therein, comprising a body with a central opening extending along a longitudinal axis through it, and a plurality of channels extending from an outer side wall of the body to an inner side wall. At least one first channel can intersect at least one other channel, with the throttle discs arranged around a circumference. However, the specific structure and design make the arrangement incompatible with other valves and complicate the assembly, replacement, and repair of the throttle elements or discs. The fluid flow patterns that can be achieved or adjusted are also limited.

The same applies to the printed version. EP 2 825 723 A2 , which describes a throttle with a piston or a control piston.

The printed matter CN 1 15 492 987 A This concerns an adjustable combined lamella structure comprising a lamella assembly used to adjust the flow rate of the throttle valve. The lamella assembly includes throttle lamellae with grooves formed in their surfaces, and drainage holes extending through the front and back surfaces of the entire throttle lamellae. The multiple throttle lamellae are stacked sequentially and rotatably mounted in a sleeve-like configuration on the guide rod.

The printed matter DE 31 44 609 A1 This concerns a valve with several valve seats arranged one behind the other in the direction of flow, each of which interacts with a movable closing element.

The printed matter DE 10 2021 120 551 A1 relates to a throttling channel for a throttling body for reducing the fluid pressure at a control valve for arrangement in a process fluid line of a process plant, such as a chemical plant, a power plant, a brewery or the like, wherein the throttling body is formed additively in layers in one build-up direction, and comprises a throttling channel profile extending from an upstream throttling channel inlet to a downstream throttling channel outlet, wherein the throttling channel has a throttling channel cross-section having a gable arc and at least one overhang surface immediately adjoining the gable arc, the overhang angle of which does not exceed an angle threshold of at most 75°, wherein the throttling channel has a throttling channel width transverse to the build-up direction and wherein the gable arc defines an arc width w in the range of 5% to 30% of the throttling channel width B.

The printed matter DE 830 142 B This concerns a shock absorber for a diaphragm stressed by liquid or gas, e.g. for diaphragm-controlled valves.

The object of the present invention is to overcome the disadvantages of the known prior art and in particular to provide an improved throttle connection, as well as an improved, in particular usable, adjustable throttle element and/or fixed throttle element, which not only increase the modularity, flexibility and/or compatibility but also have improved flow and/or throttling properties.

The invention relates to a method for providing different fluid profiles, in particular fluid characteristics, of a fluid flow by means of

• - a modular throttle receptacle according to one or more of the aspects and/or embodiments of the invention described herein and/or
• - a controllable throttle module according to one or more of the aspects and/or embodiments of the invention described herein, and/or

A "throttle receptacle" can be understood as a body, structure, device and/or part, e.g. a component, that is designed to accommodate several, in particular different and/or essentially identical, throttle modules, for example, adjustable throttle modules and/or fixed throttle modules described herein.

The throttle receptacle according to the invention can comprise or be formed by a housing body. The housing body can include an inlet opening or process fluid inlet and an outlet opening or process fluid outlet, for example, for a process fluid, as well as a through-opening or process fluid passage arranged between the process fluid inlet and the process fluid outlet. The housing body can also include an actuation opening for inserting an actuating rod and/or a control piston (and/or optionally an actuator). Furthermore, a cover, e.g., a housing cover, can be provided, which is attached or attachable to the housing body, for example, for closing and/or covering the actuating opening. The housing cover can have a through-opening, in particular extending in the direction of a stroke axis, for the actuating rod and/or the control piston or the like. The actuating rod or the control piston can be translationally movable along the stroke axis H, e.g., in the axial direction of the housing body and/or the actuating rod. The control piston can be actuated by means of the actuating rod or a valve rod.

When this text refers to an essentially "vertical," "axial," or "perpendicular" direction, it may mean a direction that essentially corresponds to the direction of the stroke axis of the control valve and/or the direction of gravity (and vice versa). Similarly, when this text refers to an essentially "horizontal" or "transverse" direction, it may mean a direction that essentially corresponds to a direction perpendicular to the direction of the stroke axis and/or the direction of gravity. Other directions, such as those described above, may be explicitly mentioned.

At the process fluid inlet and outlet of the housing, mounting devices, such as flange-like fastening sections, can be provided for connecting a pipeline for conveying process fluid, in particular a process fluid pipeline, e.g., of the process plant. It is conceivable that the mounting devices can be detachably attached to the process fluid pipeline, e.g., by means of screw connections.

The throttle body and/or the housing can be a single-piece body made of one or more media- and/or temperature-resistant materials. For example, the throttle body and/or the housing can be a single-piece metal casting or forging, with sections of a machined surface, such as polished and/or coated, for example, painted, powder-coated, chrome-plated, enamelled, electroplated, or the like. It is preferred that the housing defines an interior space, the openings of which are preferably exclusively the process fluid inlet, the process fluid outlet, and the actuating opening. It is conceivable that the housing has further openings to the interior space, for example, openings for inserting sensors or one or more additional process fluid inlets or outlets.

The housing cover is designed and configured to cover and/or close the actuation opening. In particular, the housing cover may include a mounting section for attaching an actuator, especially a pneumatic one, or a yoke, coupling structure, especially a lantern, or the like for supporting an actuator. A corresponding mounting section may also be present on the housing body. Manual, pneumatic, hydraulic and/or electric drives can be used.

The through-opening can be free of sealing materials for sealing between the housing cover and the actuating rod. The through-opening can be free of guides, such as a plain bearing, a ball bearing, or the like, for the translational guidance of the actuator. The housing cover can be made of a temperature- and/or media-resistant material. It is conceivable that the same material is selected for both the housing body and the housing cover. The housing cover and the housing body can be designed for mounting the housing cover in direct contact. For example, the housing body and the housing cover can have corresponding flange sections for attaching the housing cover to the housing body. A coupling structure, in particular a lantern, can also be provided between them, but this is not mandatory. The housing cover can have a plate-like cover section, which is preferably designed to completely close the actuating opening of the housing body in the radial direction and in the circumferential direction with respect to the stroke axis, with the exception of the through-opening.

The inventive aspects and/or embodiments of the throttle device described herein may be suitable, designed, set up and/or configured for a process plant, such as a chemical plant, a power plant, a food processing plant or the like, in particular for adjusting a process fluid flow of the process plant.

The housing body of the throttle receptacle according to the invention can form a receiving space which is set up, configured and/or designed to receive or insert "different throttle modules".

The term "different throttle modules" can be understood to mean, for example, that several throttle modules, in particular different and/or essentially identical ones, can be included. For instance, adjustable throttle modules and/or fixed throttle modules as described herein can be included. As an example, it is possible that i) two or more throttle modules, e.g., two or more fixed throttle modules with essentially identical throttle channel profiles or geometries, are included and/or used within the device. Furthermore, it is possible that ii) two or more fixed throttle modules, e.g., with different throttle channel profiles or geometries, are included and/or used within the device. Furthermore, iii) various combinations of adjustable throttle modules with fixed throttle modules, e.g., as described in point i) and/or ii), are also possible. The number of throttle modules can also be varied. In other words, the receiving space is dimensioned and/or designed to receive a plurality of different or substantially identical throttle modules, in particular the throttle modules described herein. The throttle modules and the throttle receiver described herein can therefore also be understood as a kit, e.g., a throttle receiver kit comprising a plurality of different and/or substantially identical throttle modules according to one or more of the inventive aspects and/or embodiments described herein.

The receiving space can be dimensioned such that several throttle modules described herein can be arranged one behind the other, in succession, and/or one above the other, particularly in the direction of the stroke axis or axial direction. The throttle modules can be held in the receiving space, for example, by force-fit and/or form-fit.

A "modular" choke housing can therefore be understood here to mean that several choke modules, in particular different and/or essentially identical ones, such as the adjustable choke modules and/or fixed choke modules described herein, can be inserted, placed, arranged, or positioned within the housing space. The housing space can, for example, always have the same dimensions; thus, no adaptation, modification, and/or alteration of it is necessary to accommodate the choke modules, in particular the different and/or essentially identical ones. In this way, choke modules can be easily combined, exchanged, installed, removed, and/or changed, and/or combined or assembled as needed. Furthermore, the receiving chamber, in particular its design, dimensions, and/or arrangement, makes it possible to control, monitor, regulate, and/or adjust one or more, e.g., different fluid flows, jets, and/or streams, without, for example, having to adapt or modify the housing body, or without, for example, being forced to provide different housing bodies each time, especially those with different structural designs. The throttle receiver according to the invention, or the housing body and/or the receiving chamber, thus realizes a modular structure that can be combined with a plurality of components described herein. This can be compatible with various throttling elements. This not only saves resources and time during assembly and maintenance, but also allows for greater flexibility and multiple applications. A control valve that is equipped, for example, with the modular throttle receptacle according to the invention can be referred to as a modular control valve.

According to the invention, the size of the receiving space can be matched to the size of the different throttle modules such that, when inserted into the receiving space, the different throttle modules bear against a wall of the housing body, particularly in a sealing manner, on the outside, especially in the circumferential direction. Alternatively or additionally, the different throttle modules can be arranged next to, one below, or one above the other, particularly in the axial direction. Alternatively or additionally, it is possible to insert the different throttle modules individually into the housing body. For example, the different throttle modules can individually bear against the housing body or its wall, particularly in the axial direction.

The term "size" can refer to a dimension, such as the width, length, and/or height of the receiving space. The height of the receiving space can be measured along the axis of travel, i.e., in the axial direction of the housing body. The width of the receiving space can be measured essentially perpendicular to the axis of travel and/or be limited by a wall of the housing body. The receiving space can be rotationally symmetrical, e.g., essentially cylindrical, for example, with an essentially circular cross-section. The receiving space can extend or follow a essentially straight line in the axial direction, i.e., have an essentially constant cross-section. However, other shapes and/or cross-sections are also conceivable.

The receiving space can be limited, particularly in the axial direction of the housing body or in the direction of the stroke axis, by at least one shoulder, especially an axial stop. The at least one shoulder can be formed in or through a wall of the housing body, e.g., integrally with it, in one piece, or layer by layer. The at least one shoulder can determine and/or define the height of the receiving space, for example, an insertion height of the receiving space for the different throttle modules. For example, the position, arrangement, and/or placement of the at least one shoulder in the axial direction or in the direction of the stroke axis can determine the height of the receiving space and/or how many throttle modules can be inserted or placed in it, e.g., one above the other, one below the other, or one after the other. The at least one shoulder can also serve as a stop to, for example, fix, hold, and/or support the throttle modules in the axial direction. In this way, axial support for the throttle modules can be provided.

The receiving space can be located, at least partially and/or section by section, in the area of the through-hole or process fluid passage of the housing body, for example, essentially between the process fluid inlet and outlet. The receiving space can be dimensioned and arranged within the housing body such that the process fluid enters the various throttle modules "essentially in the axial direction" or in the direction of the stroke axis of the housing body and/or flows through them sequentially. The position and arrangement of the receiving space can ensure that a process fluid flows essentially in the axial direction or in the direction of the stroke axis through the receiving space and any throttle modules that may be arranged therein, thereby allowing the process fluid to exert an axial force on these modules, which can (additionally) fix the throttle modules in the axial direction, e.g., press them against the at least one shoulder. In this context, the term "flow in an essentially axial or vertical direction" should not be understood as an absolute, i.e., purely axial or vertical, flow, but rather as an effective flow, i.e., the process fluid can, for example, flow at least partially/section by section within the throttle modules (e.g., in a throttle channel) also in a radial direction or transversely to the stroke axis (e.g., radial partial flows/flows, for example in the plane, are also conceivable), but overall or effectively in an axial direction through the receiving space or the throttle modules.

The throttle modules, when inserted into the receiving chamber, can, on the outside, particularly in the circumferential direction, essentially completely abut a wall of the housing body, especially in a substantially sealing manner. "Substantially sealing" can be understood to mean that the process fluid preferably cannot or does not flow between the wall of the housing body and a circumferential surface of one or more throttle modules, particularly those inserted into the receiving chamber. Rather, as mentioned above, the process fluid flows essentially in the axial or vertical direction, or in the direction of the stroke axis, through the receiving chamber, i.e., for example, further inwards in the radial direction and through the [unclear - possibly referring to the throttle modules]. Arrangable throttle modules, for example through the throttle channels.

The at least one paragraph can define the insertion height such that the different throttle modules can be inserted into the receiving space to at least 60%, in particular at least 70%, preferably at least 85%. Alternatively or additionally, the different throttle modules can be inserted into the receiving space to a substantially maximum of 85%, substantially at most 70%, preferably at most 60%. This can be understood, for example, to mean that a wall or height of the receiving space is such that a large proportion (e.g., a total height) of the throttle modules can be inserted into it, and, when inserted, only an insignificant proportion, e.g., the aforementioned percentage, protrudes from the receiving space in the direction of the stroke axis. This ensures, for example, that the throttle modules can be held firmly or securely in the receiving space and/or provides an advantageous fixation. The different throttle modules can be connected in series within the receiving space, in particular one above the other and/or one below the other, and/or arranged sequentially in the direction of fluid flow, for example individually. In other words, the different throttle modules can be arranged adjacent to one another and/or stacked on top of or above each other within the receiving space, for example in such a way that the process fluid can pass through the throttle modules sequentially, particularly in the direction of the stroke axis.

The throttle receptacle according to the invention, in particular the housing body, can be designed as an angle valve. For example, the inlet opening and the outlet opening can be arranged essentially at right angles to each other. The receiving chamber can be located essentially below a center line of the inlet opening, or be arranged and/or formed there. This ensures that the process fluid enters the receiving chamber essentially in an axial direction.

According to the invention, an adjustable throttle module, in particular for a modular throttle mount according to one or more of the aspects of the invention and/or embodiments described herein, can be provided for controlling, in particular for adjusting and/or regulating, one or more fluid flows, fluid jets and/or fluid currents, in particular in a process engineering plant, such as a chemical plant, a power plant, a food processing plant, or the like.

A "controllable throttle module" can be understood as a device, structure, assembly, part, component, element, and/or subassembly that is designed and/or configured to influence and/or change a fluid, in particular a process fluid flow, especially one or more of its parameters, such as volumetric flow rate, flow rate, velocity, and/or pressure. "Controllable" can refer, for example, to the ability to actively make settings/adjustments, meaning that the fluid, especially the process fluid flow, can be controlled, varied, changed, and/or regulated, for example, as a result of the position or movement of the control rod and/or a control piston. Controllable throttle modules can therefore be capable of providing, adjusting, and/or controlling different fluid profiles, fluid jets, and/or fluid flows, for example, depending on the position, orientation, and/or orientation of the control rod or the control piston.

According to the invention, a fixed throttle module, in particular for a modular throttle mount according to one or more of the aspects and/or embodiments described herein, and/or in particular for, preferably fluidically, connection with an adjustable throttle module according to one or more of the aspects and/or embodiments described herein, can be provided for controlling, in particular for adjusting and/or regulating, one or more fluid flows, fluid jets and/or fluid currents, in particular in a process plant, such as a chemical plant, a power plant, a food processing plant, or the like.

In contrast to an adjustable throttle module, a fixed throttle module can be understood as a device, structure, assembly, part, component, element, and/or subassembly in which no variable or adjustable setting or adaptation of the fluid, in particular the process fluid flow, is possible, especially of one or more of its parameters, e.g., volume flow, flow rate, velocity, and/or pressure, etc. In other words, fixed throttle modules can have a fixed, unchangeable, predetermined, and/or static structure or configuration, e.g., throttle channel profiles and/or geometries, orifice diameters, dimensions, etc. Fixed throttle modules therefore cannot be "adjustable." However, fixed throttle modules can be capable of providing, adjusting, regulating, and/or controlling different fluid profiles, jets, and/or flows, e.g., compared to a fluid profile and/or flow when no fixed throttle module is used. This can be achieved, for example, by providing, e.g., i) multiple fixed throttle modules. dulen, ii) (structurally) different fixed choke modules and/or iii) combinations or number of fixed choke modules, are realized.

The following section will first discuss an example of an adjustable throttle module.

A controllable throttle module according to the invention can comprise a fluid control body with a substantially cylindrical section. The substantially cylindrical section can be configured and/or arranged for engagement, particularly in a form-complementary manner, with a substantially hollow cylindrical control piston. The substantially cylindrical section can preferably be essentially solid cylindrical. The substantially cylindrical section can have, for example, on an outer surface, in particular a circumferential or cylindrical surface, at least one elongated recess, in particular a slot, a groove, or a groove. The at least one elongated recess, in particular the slot, can extend in the axial direction of the fluid control body and/or run in this direction, for example, substantially in a straight line. However, other configurations, e.g., curved, stepped, and/or kinked configurations, are also conceivable. The at least one elongated recess, in particular the slot, can extend in the axial direction of the fluid control body substantially completely over the outer surface, in particular the circumferential or cylindrical surface. The at least one elongated recess, in particular the slot, can have different cross-sections or cross-sectional shapes. A fluid flow, in particular a fluid characteristic curve, can be adjustable via the cross-section of the at least one elongated recess. For example, the at least one elongated recess, in particular the slot, can have a substantially circular cross-section. Other cross-sections are also possible. It is possible that the cross-section changes or varies, for example, in the direction of extension of the at least one elongated recess, in particular the slot, and thus tapers, for example, in a V-shape. The taper can be continuous, e.g., gradual or steady; or abrupt, e.g., initially essentially straight and only tapering after a certain distance.

The fluid control body can comprise a substantially disk-shaped section configured to provide a sealing surface or sealing edge for the substantially hollow cylindrical control piston, in particular its end face. For example, the substantially disk-shaped section can be substantially flat and/or planar, or even disc-shaped. The substantially disk-shaped section can be connected to, and in particular adjoin, the substantially cylindrical section; these sections can be manufactured, for example, as a single piece and/or in layers. The substantially disk-shaped section can have a larger outer diameter than the substantially cylindrical section, for example, such that the substantially cylindrical section and the substantially disk-shaped section form a shoulder, in particular a circumferential one, such as a radial shoulder extending, for example, in the circumferential direction of the fluid control body.

The at least one elongated recess, in particular the slot, can extend axially through the section of the fluid control body, which is in particular substantially disc-shaped, preferably substantially completely, and in particular define and/or form a fluid passage opening for a process fluid therein. The design, structure and/or construction of the fluid control body is simple and cost-effective to manufacture; in particular, the fluid control body can be designed as a single-piece body made of one or more media- and/or temperature-resistant materials, for example, a metal.

A controllable throttle module can comprise a substantially hollow cylindrical control piston, which can be designed in a substantially cup-shaped or sleeve-shaped form, e.g., substantially hollow cylindrical, with one side or surface being closed. The substantially hollow cylindrical control piston can be dimensioned and/or designed to engage with the fluid control body, preferably to accommodate it, in particular for controlling or regulating one or more fluid flows and/or fluid currents via the at least one elongated recess, in particular the slot. The dimensions of the substantially hollow cylindrical control piston, in particular the cavity, can therefore be matched to the dimensions of the fluid control body, e.g., in a form complementary manner. The substantially hollow cylindrical control piston, in combination with the fluid control body, can also be referred to as a fluid regulating device, element, or assembly. For example, the essentially hollow cylindrical control piston can be dimensioned and/or designed to enclose, preferably cover, the outside, in particular the circumferential surface or lateral surface, of the essentially cylindrical section, such that the at least one elongated recess, in particular the slot, and/or the fluid passage opening in the essentially disc-shaped section, by which the control piston is preferably controlled, can be released and/or closed, in particular at least partially and/or substantially completely.

For example, the control piston can have a first position in which the at least one elongated recess, in particular the slot, and/or the fluid passage opening in the essentially disc-shaped section is substantially open, for example, at least partially/sectionally and/or substantially completely. This can be referred to as the open position or open state. The control piston can have a second position in which the at least one elongated recess, in particular the slot, and/or the fluid passage opening in the essentially disc-shaped section is substantially obstructed, blocked, and/or closed. This can be referred to as the closed position or closed state. By moving the control piston, in particular in the direction of the stroke axis, e.g., between the first and second positions, different fluid flows, in particular fluid characteristics, and/or different cross-sections for controlling and/or regulating the process fluid, e.g., actively, can be set, or the process fluid flow can also be substantially completely blocked.

The essentially hollow cylindrical control piston can have an end face/closing surface, particularly at its end (e.g., viewed in the direction of the stroke axis), such as a sealing surface or sealing edge, which, especially in a closed state of the controllable throttle module, rests against the essentially disk-shaped section of the fluid control body, particularly in a sealing manner, for example, against a substantially flat, planar, and/or shallow surface formed there, such as a seat/sealing surface. The essentially disk-shaped section, particularly the seat, can form a contour with the sealing surface, particularly at its end, which is complementary in shape or parallel to the surface (e.g., a seat contour and/or a sealing contour or sealing edge) and can serve for closing (e.g., closed position or closed state). Depending on the fluid and/or degree of sealing or sealing class, this contour can also be designed or formed differently.

The adjustable throttle module can include a clamping element, in particular a substantially sleeve-shaped one. A "substantially sleeve-shaped clamping element" is understood to be a body, element, part, component, and/or structure that is essentially cylindrical, in particular hollow cylindrical. The clamping element, in particular a substantially sleeve-shaped one, can be formed in one piece and/or manufactured layer by layer, for example, from metal, e.g., from the same material as the housing body and/or the fluid control element. The clamping element, in particular a substantially sleeve-shaped one, can be configured, in particular in the assembled state:

• - to fix the fluid control body, in particular the essentially disc-shaped section, in the axial direction of the fluid control body, in particular by pressing, clamping and/or clamping it; In particular, the essentially sleeve-shaped clamping element may also have an end face, e.g. in the axial direction, which can bear against the essentially disc-shaped section, in particular in a sealing manner. This can provide additional axial fixing and/or clamping for the fluid control body and/or, if applicable, further throttle modules; and/or
• - to accommodate, surround and/or enclose the essentially hollow cylindrical control piston, and/or to center it in the radial direction of the fluid control body, preferably on the circumference or in the circumferential direction of the essentially hollow cylindrical control piston; This can prevent and/or minimize a danger or risk of, for example, radial deflection, deviation and/or buckling of the control piston (e.g. with respect to a stroke axis), especially at high process pressures.

The clamping element, which is essentially sleeve-shaped, can include at least one opening. This opening can be designed like a window or in a window-like manner in an outer wall or on the outer circumference of the essentially sleeve-shaped clamping element. It is also possible to provide several openings, for example, with essentially identical dimensions (e.g., length, width, height), which can be arranged, for example, in a circumferentially uniform manner, e.g., at uniform intervals. However, different and/or varying distances are also conceivable. A number of the openings can be aligned with or correspond to a number of the elongated recesses of the fluid control body. The opening can be dimensioned and/or arranged, particularly in the assembled state, such that the elongated recess, in particular the slot, of the fluid control body is at least partially/sectionarily exposed. The opening can The clamping element, which is essentially sleeve-shaped, can serve solely for axial/radial clamping or centering, whereby the at least one elongated recess, in particular the slot, of the fluid control body is released or closed by the essentially hollow cylindrical control piston.

In a first embodiment, a fixed throttle module is provided, in particular for a modular throttle mounting according to one or more of the aspects and/or embodiments of the invention described herein, and/or in particular for, preferably fluidically, connection with an adjustable throttle module according to one or more of the aspects and/or embodiments of the invention described herein, for controlling, in particular for adjusting and/or regulating, one or more fluid profiles and/or fluid flows, in particular in a process engineering plant, such as a chemical plant, a power plant, a food processing plant, or the like.

The fixed throttle module according to the invention can comprise at least one substantially disc-shaped throttle element, which includes at least one throttle channel, for example formed therein. The at least one throttle channel can extend between at least one fluid inlet area and at least one fluid outlet opening.

A "throttling channel" can be defined as a channel, passage, and/or passageway that has a specific geometry (e.g., course, shape, cross-section, orientation, inclination, direction, etc.) and/or specific dimensions and is designed to guide, direct, and/or control a fluid, particularly a process fluid, or to influence the fluid as it passes through the throttling channel, for example, to regulate the flow rate, such as slowing it down, throttling it, and/or reducing it. In particular, one or more parameters of the fluid, such as volumetric flow rate, flow rate, velocity, and/or pressure, etc., can be influenced or changed by a throttling channel.

A "fluid inlet area" can be understood as a section, area, and/or location or region where a fluid can enter, but where the fluid cannot (e.g., completely) penetrate or exit the throttling element, but is instead directed, for example, radially or in a plane. A fluid inlet area can, for example, be a recess, particularly a groove, with a depth less than the thickness of the essentially disc-shaped throttling element. A "fluid outlet opening," on the other hand, can be understood as a section, area, and/or location or region where the fluid can exit or leave the throttling element. The at least one fluid outlet opening can be designed as a through-hole, i.e., it can essentially completely penetrate the throttling element.

According to the invention, the at least one throttle channel can be inclined, in particular oblique, and/or angled with respect to a surface, in particular a cross-sectional area, of the at least one substantially disk-shaped throttle element. In particular, the at least one throttle channel can be inclined, in particular oblique, and/or angled with respect to the, for example, flat, planar, and/or planar surface or top surface of the substantially disk-shaped throttle element. For example, the at least one throttle channel can be designed as a depression or recess, in particular as a groove or channel, wherein the depth of the at least one throttle channel can change or vary. For example, the depth of the at least one throttle channel can increase from the at least one fluid inlet area to the at least one fluid outlet opening, for example continuously, steadily, and/or gradually. Abrupt changes in the form of steps are also conceivable. This creates a kind of self-cleaning effect, even when the valve is closed, because the fluid, especially the process fluid, can flow out through the slope, angle, and/or inclination, carrying impurities with it. The at least one throttle channel can, for example, run at least at an angle of approximately 2°, 3°, 5°, 7°, 10°, 20°, 25°, 30°, 35°, 40°, 45°, or even more than 45° (e.g., 50°, 60°, 75°) with respect to the surface, especially the cross-sectional area, of the at least one substantially disc-shaped throttle element. The angle, or angular value, of the at least one throttle channel can, for example, depend on the thickness of the substantially disc-shaped element; for example, a greater thickness allows for a larger angle or inclination to be selected and/or provided.

In a second embodiment, which can be combined with one or more of the aspects and/or embodiments of the invention described herein, a fixed throttle module is provided, in particular for a modular throttle receptacle according to one or more of the embodiments described herein. described aspects of the invention and/or embodiments, and/or in particular for, preferably fluidic, connection with a controllable throttle module according to one or more of the aspects of the invention and/or embodiments described herein, for controlling, in particular for adjusting and/or regulating, one or more fluid flows and/or fluid currents, in particular in a process engineering plant, such as a chemical plant, a power plant, a food processing plant, or the like.

The fixed throttle module can comprise at least two substantially disc-shaped throttle elements, which can be arranged in series, one after the other, and/or one above the other or stacked, particularly in the flow direction of a process fluid and/or in the direction of the stroke axis. The at least two substantially disc-shaped throttle elements can form at least one common fluid flow channel. The at least one common fluid flow channel can extend through both of the at least two substantially disc-shaped throttle elements. A "common fluid flow channel" can be understood as a channel, passage, and/or passage that connects a channel of a first of the at least two substantially disc-shaped throttle elements with a channel of a second of the at least two substantially disc-shaped throttle elements, particularly fluidically, so that, for example, the fluid can pass through and/or penetrate the at least two substantially disc-shaped throttle elements via the first and second, i.e., the common, fluid flow channel. The idea behind a common fluid flow channel is that the essentially disc-shaped throttling elements can cooperate or work together to influence, for example, the fluid flow. By changing, for example, the position, orientation, or the like, for instance by rotating or turning, and/or by selecting/combining specific or different essentially disc-shaped throttling elements and/or a number of them, the common fluid flow channel can be altered, modified, and/or adapted, which in turn changes the flow.

The fixed throttle or the essentially disc-shaped throttle elements can, for example, be inserted, placed, arranged, and/or received in the receiving space of the throttle housing, e.g., one above the other. The essentially disc-shaped throttle elements can thus be easily combined, exchanged, and/or installed/removed, changed, and/or, e.g., as needed/required, combined and assembled to form, for example, various common fluid flow channels. It is also possible, e.g., after installation or assembly, to change the orientation of the at least two essentially disc-shaped throttle elements relative to each other, e.g., by rotating them, in order to influence or modify the common fluid flow channel. Thus, one or more, e.g., different, fluid flows and/or fluid currents can be controlled, monitored, regulated, and/or adjusted, giving the fixed throttle according to the invention a modular design.

The at least two essentially disc-shaped throttle elements can be essentially identical in design, or they can differ, for example, with regard to a geometric design, e.g., one or more throttle channels, and/or dimensions (e.g., thickness) and/or material. For example, the at least two essentially disc-shaped throttle elements can each have different throttle channels that differ from one another in particular in their course, orientation, shape, inclination, direction, cross-section, and/or size or dimension (e.g., length, width, height).

The common fluid flow channel can be configured to guide the process fluid sequentially through the at least two essentially disc-shaped throttling elements, wherein, in particular, the common fluid flow channel guides the process fluid essentially vertically or axially through the at least two throttling elements. As already mentioned, "essentially axial or vertical" is not to be understood as an absolute, i.e., purely axial or vertical, flow, but rather as an effective flow. This means that the process fluid can, for example, flow at least partially/sectionarily in a radial direction or transversely to the stroke axis within the at least two essentially disc-shaped throttling elements (for example, in a throttling channel) (e.g., radial partial flows/flows, for example in the plane, are also conceivable), but overall or effectively in an axial or vertical direction through the at least two essentially disc-shaped throttling elements.

The at least two essentially disc-shaped throttle elements can each comprise at least one throttle channel; for example, a first essentially disc-shaped throttle element can form a first throttle channel and a second essentially disc-shaped throttle element can form a second throttle channel. The first and second throttle channels can be configured as follows: As already mentioned, the throttle channels can be essentially identical in design, or differ as mentioned above, with reference to the explanations above in this regard. The first and/or second throttle channel can each extend between at least one fluid inlet region and at least one fluid outlet opening. The fluid outlet opening of a throttle channel of one of the at least two essentially disc-shaped throttle elements (for example, a fluid outlet opening of the first throttle channel of the first essentially disc-shaped throttle element) can be connected, coupled, and/or aligned with the fluid inlet region of a throttle channel of a second of the at least two essentially disc-shaped throttle elements (for example, a fluid inlet region of the second throttle channel of the second essentially disc-shaped throttle element), particularly fluidically. As an example, the first and second essentially disc-shaped throttle elements can be arranged and/or aligned with each other such that the fluid outlet opening of the first throttle channel is located directly above the fluid inlet region of the second throttle channel, but not, for example, above the fluid outlet opening of the second throttle channel. In this way, the fluid is forced to first penetrate (e.g., essentially completely) the fluid inlet area or the second throttle channel before reaching the fluid outlet opening of the second, essentially disc-shaped throttle element. As mentioned, this allows one or more fluid paths and/or flows to be advantageously controlled, adjusted, and/or regulated.

Different fluid flow patterns, particularly fluid characteristics, can be achieved by varying or combining different throttling modules, e.g., with regard to their number and design.

It is also possible to change the orientation of the at least two essentially disc-shaped throttling elements relative to each other, e.g., by rotating them, in order to influence and/or provide different fluid flow patterns, particularly fluid characteristics.

Furthermore, the method can control, in particular adjust, a damping of the fluid flow by varying a number and/or a design, in particular a structure or geometric design, for example of the throttle channels, as mentioned above, of the at least two essentially disc-shaped throttle elements.

1A-D Figure 1 shows a fluid control element 100 of an adjustable throttle module according to an exemplary embodiment. An adjustable throttle module is used, for example, in the 3A-D and 4A-B A more detailed explanation. 1A is a perspective view of the fluid control body 100 and 1B A top view of the fluid control body 100. 1C is a side view of the fluid control body 100 and 1D a sectional view through section AA from 1C .

As in the 1A-D As can be seen, the fluid control body 100 can comprise a substantially cylindrical section 102. The substantially cylindrical section 102 can have, for example on an outer surface 104, in particular a circumferential surface or lateral surface of the substantially cylindrical section 102, at least one elongated recess 106, in particular a slot, a groove or a slot. In the 1A-D In particular, two essentially elongated recesses 106 are shown, which are essentially opposite each other, whereby more or fewer may also be provided in the fluid control body 100.

The at least one elongated recess 106 can be oriented in the axial direction, or in the direction of the stroke axis H (szB 4A /B), of the fluid control body 100 extend and/or run in this direction, for example essentially straight, as at section AA in 1C as can be seen. However, other configurations, e.g., curved, stepped, and/or kinked configurations, are also conceivable. The at least one elongated recess 106, in particular the slot, can extend in the axial direction of the fluid control body 100 essentially completely over the outer surface 104, in particular the circumferential surface or lateral surface. As in 1C As can be clearly seen, the at least one elongated recess 106, in particular the slot, has a cross-section that changes or varies, for example, in the direction of extension of the at least one elongated recess 106, i.e., it tapers, for example, in a V-shape. The essentially elongated recess 106 can, for example, taper in the direction of the essentially disk-shaped section 108. Advantageous flow and throttling properties can be provided by such a cross-section and/or by the arrangement of the recess 106 along the outer surface 104, enabling high pressures to be dissipated with low noise and stress. builds and demanding process fluids, safely or reliably throttled or controlled, adjusted and/or regulated.

The fluid control body 100, as in the 1A-D shown, can comprise an essentially disc-shaped section 108 which is designed to form a sealing surface or sealing edge (e.g. seat or sealing surface 380, in particular in 3A /C) for an essentially hollow cylindrical control piston (see control piston 320 e.g. in 3A, 3C and 4A-4B) , in particular its end face (see closure surface 370 in particular) 3C to provide. 1A-D As shown, the substantially disc-shaped section 108 can be substantially flat, planar and/or planar, for example, plate-like. The substantially disc-shaped section 108 can be connected to the substantially cylindrical section 102. The section shown in the 1A-D The fluid control body 100 shown, i.e., the essentially cylindrical section 102 and the essentially disc-shaped section 108, can be manufactured, for example, from a single piece and/or layer by layer, e.g., from metal, and/or, for example, by means of a 3D printing process. As, for example, in 1B As can be seen, the essentially disc-shaped section 108 can have a larger outer diameter d1 than the essentially cylindrical section 102 (see diameter d2). The ratio between d1 and d2 can be such, for example, that the essentially cylindrical section 102 and the essentially disc-shaped section 108 form a step, particularly a circumferential one, for example a radial step, which runs, for example, in the circumferential direction of the fluid control body 100, e.g., step 109 in 1B The ratio between d1 and d2 can also be chosen such that the values in the 3A /C recognizable seating or sealing surface 380 (or paragraph 109) of a sufficient size for the sealing surface 370 (see 3C ) of the control piston 320.

As in average AA of the 1D To be recognized, the at least one elongated recess 106, in particular the slot, can extend in the axial direction of the fluid control body 100 through the, in particular substantially disc-shaped, section 108, preferably substantially completely, and in particular a fluid passage opening 110 (see below) 1B and 1D ) define and/or train for a process fluid, thereby providing advantageous flow and throttling properties.

2A-D show a fluid control body 200 of an adjustable throttle module according to an exemplary embodiment. 2A is a perspective view of the fluid control body 200 and 2B A top view of the fluid control body 200. 2C is a section view through section AA from 2B and 2D This is a side view of the fluid control body 200.

The basic structure of the fluid control body 200 in the 2A-D is essentially identical to the fluid control body 100 of the 1A-D , so that reference can be made to the previous statements in this regard, whereby reference can be made to the 2A-D Appropriately adapted reference symbols are used. The fluid control body 200 of the 2A-D However, it differs in the cross-section of the at least one elongated recess 206, in particular the slot and/or the fluid passage opening 210. As in the 2A-D As can be seen, the at least one elongated recess 206, in particular the slot and/or the fluid passage opening 210, has a substantially round cross-section that does not include a taper. It has been shown that even with the one in the 2A-D The cross-section shown and/or the arrangement of the recess 106 along the outer surface 104 also provide advantageous flow and throttling properties, with which high pressures can be reduced with low noise and stress, and demanding process fluids can be throttled or controlled, adjusted and/or regulated safely and reliably.

3A-D shows an assembly 300, which includes an adjustable throttle module with a fluid control element, for example a fluid control element 100 as in the 1A-D shown (where it is clear that alternatively the fluid control body 200 as in the 2A-D as shown, as well as a control piston 320, which is attached and/or fastened to an exemplary actuating rod 325, and a clamping sleeve, as well as a fixed throttle module 340, which comprises three exemplary essentially disc-shaped throttle elements 350A-C, in particular throttle discs. In other words, the 3A-D The figures show a combination of an adjustable throttle module and a fixed throttle module comprising several throttle elements, in particular throttle discs. It should be noted that this configuration/arrangement is only exemplary; that is, fewer throttle discs 350A-C can also be used (e.g., only one), or one or more of the throttle discs 600-800 can be used, as in the figures shown. 6A-D, 7A-D and 8A-D They can be shown, used, assembled and/or combined. Furthermore, it should be clear that, for example, only one of the two, i.e., exclusively the adjustable throttle module (see, e.g., [reference]), can be used. 5B) e.g. with fluid control body 100/200, control piston 320 and clamping sleeve, or exclusively the fixed throttle module (see e.g. 5A) e.g. with one or more 350A-C choke elements and/or 600-800, as e.g. in the 6A-D, 7A-D and 8A-D shown, can be used.

As in 3C The adjustable throttle module can best be identified by a hollow cylindrical control piston 320, which can be designed in a substantially cup-shaped or sleeve-shaped form, e.g., substantially hollow cylindrical, with one side or surface being closed. The substantially hollow cylindrical control piston 320 can be dimensioned and/or designed to engage with the fluid control body 100, preferably to accommodate it, in particular for controlling or regulating one or more fluid flows and/or fluid flows through the at least one elongated recess 106, in particular the slot, for example by controlled opening/closing, for example, by translational movement along the stroke axis H.

As in the average of 3C To be recognized, the dimensions of the essentially hollow cylindrical control piston 320, in particular the cavity 322, can be matched to the dimensions of the fluid control body 100, in particular the essentially cylindrical section 102, e.g., be designed/configured in a form complementary manner. For example, the essentially hollow cylindrical control piston 320 can be dimensioned and/or designed to enclose the outer surface 104, in particular the circumferential or lateral surface, of the essentially cylindrical section 102, preferably to enclose, preferably to cover, or to conceal it in such a way that the at least one elongated recess 106/206, in particular the slot, and/or the fluid passage opening 110 in the essentially disk-shaped section 108, can be released and/or closed by the control piston 320, preferably in a controlled manner, in particular at least partially and/or essentially completely, for example by a movement of the control piston along the stroke axis H, in particular translationally (see, for example, position 360). 3A /3C where the control piston encloses/surrounds the circumferential surface and the recess 106). By moving the control piston 320, particularly in the direction of the stroke axis H, e.g. between a first position (cf. e.g. open position in 4A) and second position (cf. e.g. closed position in 4B) , in particular including intermediate positions, different fluid profiles, especially fluid characteristics, and/or different cross-sections for controlling and/or regulating the process fluid, e.g. actively, can be set, or the process fluid flow can also be essentially completely blocked.

The essentially hollow cylindrical control piston 320 can have a sealing surface 370, in particular at its end face (e.g. viewed in the direction of the stroke axis), e.g. a sealing surface (cf. 3C ), which, particularly in a closed state, rests against the essentially disc-shaped section 108 of the fluid control body 100, in particular sealingly, for example against an essentially flat, planar and/or planar surface formed there, for example a seat surface or sealing surface 380 (cf. 3C The essentially disc-shaped section 108, in particular the sealing surface 380, can form a contour 395 with the sealing surface, in particular the end face, which is in particular complementary in shape or parallel to the plane (e.g. a seat contour and/or a sealing contour; as best shown in the 4B to recognize) develop, which are used for closing (e.g. closed position or closed state of the 4B) can serve this purpose. However, depending on the fluid and/or degree of sealing or sealing class, this contour 395 can also be designed or formed differently.

The adjustable throttle module can include a clamping element 330, in particular a substantially sleeve-shaped one, which, as e.g. in 3A /3C, is essentially cylindrical, in particular hollow cylindrical, for example with a rotationally symmetrical or essentially circular cavity 322. The clamping element 330, in particular essentially sleeve-shaped, can be configured, in particular in the assembled state:

This can, for example, provide additional axial fixing and/or clamping for the fluid control body 100 and/or possibly also the further throttle modules 350A-C; and/or
• - to receive, surround and/or enclose the essentially hollow cylindrical control piston 320, and/or to center it in the radial direction of the fluid control body 100, preferably at the circumference or in the circumferential direction of the essentially hollow cylindrical control piston 320; This can pose a danger or risk of, for example, radial To prevent and/or minimize deflection, deviation and/or buckling of the control piston (e.g. in relation to a stroke axis H), especially at high process pressures.

The clamping element 330, which is essentially sleeve-shaped, can comprise at least one opening 390 (see below). 3A /B). The at least one opening 390 can be provided in an outer wall or on an outer circumference of the essentially sleeve-shaped clamping element 330, like a kind of window or in a window-like manner. It is also possible to provide several openings 390, which, as in 3A The at least one opening 390 can be recognizably arranged, for example, with essentially identical dimensions (e.g., length, width, and/or height) and, for example, distributed essentially uniformly in the circumferential direction, e.g., evenly spaced. The at least one opening 390 can, particularly in the assembled state, be dimensioned and/or arranged such that the at least one elongated recess 106, in particular the slot, of the fluid control body 100 is at least partially/sectionarily released (see figure). 3A , e.g. at position 360). The at least one opening 390 can be at least partially/sectionarily released both in the closed position or closed state (e.g. second position) and in the open position or open state (e.g. first position). In other words, the clamping element 330, which is in particular essentially sleeve-shaped, can serve only for axial/radial clamping or centering, wherein the at least one elongated recess 106, in particular the slot, of the fluid control body 100 is released or closed by the essentially hollow cylindrical control piston 320.

As already mentioned, in the 3A-3D also a fixed throttle module 340 shown, which includes three exemplary essentially disc-shaped throttle elements 350A-C, in particular throttle discs (e.g. also 6A-D, 7A-D and 8A-D ) includes. It should be noted that either just a single, essentially disc-shaped throttling element, or two or more, can be used.

3E Figures -F show a schematic and exemplary cross-section/path of a common fluid flow channel 375, which is e.g. through one or more of the essentially disc-shaped throttling elements 350A-C from the 3A-D , especially throttle discs (e.g. also 6A-D, 7A-D and 8A-D ) can be trained. In 3E -F is an exemplary fluid flow 375' sketched by the dashed arrow to illustrate which fluid flow is possible through the common fluid flow channel 375. It should be clear that other flows are also conceivable or possible. The following sections describe the 3E -F described by means of an example of a fixed throttle module with at least two substantially disc-shaped throttle elements 350A-B, which can be connected or stacked in series, in succession and/or above or below each other, particularly in the flow direction of a process fluid, and/or in the direction of the stroke axis, as e.g. in the 3A-D shown.

As in the 3E To recognize -F, the at least two essentially disc-shaped throttling elements 350A/B can form at least one common fluid flow channel 375, through which, for example, the fluid can flow along path 375'. The at least one common fluid flow channel 375 can run through both of the at least two essentially disc-shaped throttling elements 350A/B, e.g., path 375'. The common fluid flow channel 375 can connect a first channel 375A of a first 350A, which has at least two substantially disc-shaped throttling elements 350A/B, with a channel 375B of a second 350B, which has at least two substantially disc-shaped throttling elements 350A/B, in particular fluidically (e.g. at the point where the fluid flows, for example, via the first 375A and second 375B channels, i.e., the common fluid flow channel 375, for example, starting from the substantially elongated recess 106, which can pass through and/or penetrate at least two substantially disc-shaped throttling elements 350A/B, e.g., along path 375'. In the example of the 3E -F The fluid can, for example, exit through the throttling element 350C. This throttling element 350C can comprise or form one end of the path 375' and/or the common fluid flow channel 375 and/or can have one or more, in particular axially arranged, through-openings in order to distribute, for example, the flow, in particular the process fluid flow, into several fluid jets, preferably uniformly, e.g. in the outlet or the outlet opening and/or in its direction.

The at least two essentially disc-shaped throttle elements 350A/B can each comprise at least one throttle channel; for example, a first essentially disc-shaped throttle element 350A can form a first throttle channel and a second essentially disc-shaped throttle element 350B can form a second throttle channel. These can then be connected, in particular fluidically, for example by alignment, e.g., rotation, and thus form a common fluid flow channel 375.

The first and/or second throttle channel, as in 3E -F, shown schematically, can extend between at least one fluid inlet area and at least one fluid outlet opening, which are subsequently referred to in relation to the 6A-D, 7A-D and 8A-D will be explained. 6A-D, 7A-D and 8A-D The illustrations show essentially disc-shaped throttle elements 600-800, in particular throttle discs 600-800; according to one or more exemplary embodiments, in particular with different geometric configurations, e.g., of one or more throttle channels. For example, the essentially disc-shaped throttle elements 600-800 of the 6A-D, 7A-D and 8A-D Each has different throttle channels, which differ from each other in particular by their course, alignment, orientation, shape, (possibly also an inclination), direction, (possibly also a cross-section) and/or size or dimension (for example, length, width, height).

A fluid inlet area 620-820 can, for example, be a recess 620-820, in particular a groove 620-820, with a depth that is less than the thickness d (see. 6-8D ) of the substantially disc-shaped throttling element 600-800. The at least one fluid outlet opening 610-810, on the other hand, can be designed as a through-opening 610-810, e.g., as a bore or hole, thus, for example, substantially completely penetrating the throttling element 600-800. The fluid outlet opening 610-810 of a throttling channel of one of the at least two substantially disc-shaped throttling elements 600-800 (for example, a fluid outlet opening 610-810 of the first throttling channel of the first substantially disc-shaped throttling element 600-800) can be connected, coupled, and/or aligned with the fluid inlet area 620-820 of a throttling channel of a second of the at least two substantially disc-shaped throttling elements 600-800 (for example, a fluid inlet area 620-820 of the second throttling channel of the second substantially disc-shaped throttling element 600-800), in particular fluidically. As an example, the first and second essentially disc-shaped throttle elements 600-800 can be arranged and/or aligned with each other such that the fluid outlet opening 610-810 of the first throttle channel is located directly above the fluid inlet area 620-820 of the second throttle channel, but not, for example, above the fluid outlet opening 610-810 of the second throttle channel. In this way, the fluid is forced to first penetrate (e.g., essentially completely) the fluid inlet area 620-820 or the second throttle channel before it reaches the fluid outlet opening 610-810 of the second essentially disc-shaped throttle element. At this point, we should also refer again to path 375' from the 3E Reference is made to -F, which includes such an exemplary alignment. As mentioned, this allows one or more fluid flows and/or fluid currents to be advantageously controlled, adjusted, and/or regulated.

4A-5B show a modular throttle receptacle according to the invention, in which the exemplary throttle modules according to the invention are arranged. 3A-3D and/or 6A-8D and/or fluid control bodies 100/200 can be used. The explanations mentioned in relation to these figures apply analogously in this regard. 4A A throttle receptacle 400 according to the invention is shown, wherein the control piston 320 is in an open position, so that a fluid can enter through the substantially elongated recess 106. 4B A throttle receptacle 400 according to the invention is shown, wherein the control piston 320 is in a closed position, so that the fluid cannot enter through the substantially elongated recess 106.

It should be noted that the throttle intake according to the invention 400 of the 4A-5B is set up, configured and/or designed to accommodate or insert different throttle modules, for example adjustable throttle modules such as those found in 3A-D shown and/or fixed throttle modules, in particular throttle discs such as e.g. in 3A -F as well 6A-8D As shown, it is possible, for example, that i) two or more throttle modules, e.g., essentially, in particular structurally, the same or identical, are included and/or used in the device, e.g., two or more fixed throttle modules 350A-C, 600-800 with essentially identical throttle channel profiles or geometries. Furthermore, it is possible that ii) two or more fixed throttle modules 350A-C, 600-800, e.g., with different throttle channel profiles or geometries, are included and/or used in the device. Furthermore, iii) various combinations of adjustable throttle modules with fixed throttle modules, e.g., as according to point i) and/or ii), are also possible. Furthermore, the number of throttle modules can be varied; e.g., only a single throttle disk can be used.

The throttle intake 400 according to the invention 4A-5B The housing body 410 can comprise or be formed by a housing body 410. The housing body 410 can comprise an inlet opening 412 or a process fluid inlet and an outlet opening 414 or a process fluid outlet, for example for a process fluid, as well as a passage opening 416 or a process fluid passage arranged between the process fluid inlet and the process fluid outlet (e.g., 5A) The housing body 410 can also be a The actuating opening comprises a connecting rod 325 and/or a control piston 320 (and/or optionally an actuator). Furthermore, a cover 424, e.g., a housing cover, may be provided, which is attached or attachable to the housing body 410, for example, to close and/or cover the actuating opening. The housing cover may have a through-opening, in particular extending in the direction of a stroke axis H, for the connecting rod 325 and/or the control piston 320 or the like. The connecting rod 325 or the control piston 320 may be translationally movable along the stroke axis H, e.g., in the axial direction of the housing body 410 and/or the connecting rod 325.

At the process fluid inlet and outlet of the housing body, mounting devices 418, for example, flange-like fastening sections, can be provided for connecting a pipeline for conveying process fluid, in particular a process fluid pipeline, e.g., of the process plant. It is conceivable that the mounting devices 418 can be detachably attached to the process fluid pipeline, e.g., by means of screw connections. In particular, the housing cover can include a fastening section for mounting an actuator 450, in particular a pneumatic actuator, or a yoke, a coupling structure, in particular a lantern, or the like for supporting an actuator 450. The actuator 450 is only indicated, as manual, pneumatic-hydraulic, and/or electric drives can be used.

The housing body 410 of the throttle receptacle 400 according to the invention can form a receiving chamber 428 (e.g. 5B) , which is set up, configured and/or designed to accommodate or insert the different throttle modules, as already mentioned, for example adjustable throttle modules such as those in 3A-D shown and/or fixed throttle modules, in particular throttle discs as shown in 3A -F as well 6A-8D shown. The receiving space 428 can in particular be dimensioned such that several throttle modules described herein, in particular in the direction of the stroke axis H or axial direction, can be arranged or stacked one behind the other, one after the other and/or one above the other or one below the other.

As can be seen, several choke modules 350A-C, 600-800, for example, adjustable choke modules and/or fixed choke modules as described herein, can be inserted, placed, arranged, and/or received in the receiving chamber 428, particularly different and/or essentially identical ones. The receiving chamber 428 can, for example, always have the same dimensions; therefore, no adaptation, modification, and/or alteration of it is necessary to accommodate the choke modules, particularly the different and/or essentially identical ones. In this way, choke modules can be easily combined, exchanged, installed, removed, and/or changed, and/or combined or assembled as needed. Furthermore, the receiving chamber 428, in particular its design, dimensions, and/or arrangement, makes it possible to control, monitor, regulate, and/or adjust one or more, e.g., different fluid flows and/or fluid currents, without, for example, having to adapt or modify the housing body 410, or without, for example, being forced to provide different housing bodies 410 for each application, especially those with different structural designs. The throttle receptacle 400 according to the invention, or the housing body 410, and/or the receiving chamber, thus realize a modular design that can be compatible with a plurality of throttle elements described herein. This not only saves resources and time during assembly and maintenance but also enables greater flexibility and multiple applications.

According to the invention, a size of the receiving space 429, e.g. a dimension, for example a width, length and/or height of the receiving space 429, can be matched to a size, e.g. a dimension, for example a diameter, of the different throttle modules in such a way that the different throttle modules, in a state inserted in the receiving space 429, bear against a wall of the housing body 410 on the outside, in particular in the circumferential direction, essentially completely, in a sealing manner.

As in 4A As can be seen, the height h of the receiving space 429 can be dimensioned in the direction of the stroke axis H, i.e., for example, in the axial direction of the housing body 410. The width b of the receiving space can be dimensioned essentially transversely to the stroke axis H and/or be limited by a wall of the housing body 410. The receiving space 429 can be rotationally symmetrical, e.g., essentially cylindrical, for example, having an essentially circular cross-section. In other words, a cavity can be provided for the throttle modules. The receiving space 429 can extend or run essentially straight in the axial direction, i.e., have an essentially constant cross-section. However, other shapes and/or cross-sections are also conceivable.

What's next in 4A As can be seen, the receiving space 429, particularly in the axial direction of the housing body 410 or in the direction of the stroke axis H, can be limited by at least one shoulder, in particular an axial stop. The axial stop can define or determine the width b of the receiving space 429. The at least one shoulder 429 can be formed in or through a wall of the housing body 410, e.g., integrally with it, made from a single piece, or layer by layer. The at least one shoulder can determine and/or define the height h of the receiving space 429, for example, an insertion height h of the receiving space 429 for the different throttle modules. For example, the position, arrangement, and/or placement of the at least one shoulder in the axial direction or in the direction of the stroke axis H can determine the height h of the receiving space 429 and/or how many throttle modules can be inserted or placed in it, e.g., one above the other, one below the other, or one after the other. At least one of the steps can also serve as a stop, for example to fix, hold, and/or support the throttle modules in the axial direction. In this way, axial support can be provided for the throttle modules.

The receiving chamber 429 can be located, at least partially and/or section by section, in the area of the passage opening 416, or the process fluid passage (see 5A) The receiving chamber 429 is located, for example, essentially between the process fluid inlet and outlet of the housing body 410. The receiving chamber 429 can be dimensioned and arranged within the housing body 410 such that the process fluid enters the various throttle modules essentially in an axial direction, i.e., in the direction of the stroke axis H of the housing body 410, and/or flows through them sequentially. The position and arrangement of the receiving chamber 429 can ensure that a process fluid flows essentially in an axial direction, i.e., in the direction of the stroke axis H, through the receiving chamber 429 and any throttle modules arranged therein, thereby exerting an axial force on them. This force can (additionally) fix the throttle modules in the axial direction, e.g., press them against the at least one shoulder.

The throttle modules, when inserted in the receiving chamber 429, can bear against a wall of the housing body 410 on the outside, particularly in the circumferential direction, essentially completely, and in a substantially sealing manner, in particular such that the process fluid preferably cannot or does not flow between the wall of the housing body 410 and a circumferential surface of one or more throttle modules, particularly those inserted in the receiving chamber 429. Rather, as mentioned above, the process fluid flows essentially in the axial or vertical direction, or in the direction of the stroke axis H, through the receiving chamber 429, i.e., for example, further inwards in the radial direction and through the throttle modules that can be arranged therein, for example, through the throttle channels.

The at least one paragraph can define the insertion height h such that the different throttle modules can be inserted into the receiving space to at least 60%, in particular at least 70%, preferably at least 85%. Alternatively or additionally, the different throttle modules can be inserted into the receiving space to substantially a maximum of 85%, substantially a maximum of 70%, preferably a maximum of 60%. For example, the height h of the receiving space 429 can be such that a large proportion (e.g., the total height) of the throttle modules can be inserted into it, and, when inserted, only an insignificant, e.g., a percentage, protrudes from the receiving space 429 in the direction of the stroke axis H. This ensures, for example, that the throttle modules can be held firmly or securely in the receiving space and/or provides an advantageous fixation. As in 4A It can also be seen that the essentially disc-shaped section 108 may be included in the recording space, and, for example, only a part, e.g., the essentially cylindrical section 102, may protrude from the recording space 429.

As in the 4A-5B As can be seen, the throttle receptacle 400 according to the invention, in particular the housing body 410, can be designed as an angle valve. For example, the inlet opening 412 and the outlet opening 414 can be arranged essentially at right angles to each other. The receiving chamber 429 can be located essentially below a center line (at 412) of the inlet opening 412, or be arranged and/or formed there. This ensures that the process fluid enters the receiving chamber essentially in the axial direction or in the direction of the stroke axis H.

In 5A One possibility is shown in which the modular choke assembly according to the invention comprises exclusively a fixed choke module, for example with one or more choke elements 350A-C and/or 600-800, as e.g. in the 6A-D, 7A-D and 8A-D shown. In 5B One possibility is shown in which the modular throttle receptacle according to the invention comprises exclusively the controllable throttle module, e.g. with fluid control body 100/200, control piston 320 and clamping sleeve, whereby a spacer 431 can be used for this purpose.

The features disclosed in the foregoing description, figures and claims can be important for the realization of the invention in its various embodiments, both individually and in any combination.
