Description

The technical field to which the utility model relates.

The proposed utility model relates to pipe fittings, and in particular to shut-off and control valves.

State of the art

Known pipe fittings disclosed in patent GB 2067716 A, published July 30, 1981. Famous valves include a housing that includes an inlet pipe and an outlet pipe, between which a kinematic element is connected to the shutter. One of said nozzles comprises a throttle washer including at least one through hole and pressed against the housing by means of a tightening nut which is connected by means of a threaded connection to the nozzle. Known fittings adopted as the closest analogue.

A disadvantage of the known valves is the complexity of its installation and dismantling.

It is known that for connecting fittings, in particular, the closest analogue, with pipes, standard quick-disconnect connections can be used with or without a sealant.

In the case of using quick-disconnect joints without seals, to ensure the tightness of the connection, it is necessary to control the force applied to tighten and screw on the threaded connection elements, for example, nuts and fittings. To control the mentioned effort, it is necessary to use torque wrenches, which are not common due to the high cost. When tightening without the mentioned keys, there is a likelihood of exceeding the maximum allowable force necessary for tightening and screwing, i.e. there is a chance to “tighten” the nut, which will entail the deformation of the fittings and quick disconnect. Namely, a groove (dent) is formed at the place of their connection, which, however, does not violate the tightness of the connection. However, in the event of dismantling and replacing the fittings and / or quick disconnect joint or their components, the tightness of the new joint will be impaired. The forced use of expensive equipment when installing the connection to ensure tightness and prevent deformation of the valve and / or quick-disconnect connection complicates the installation and dismantling of the valve from a technical point of view.

Connections using a sealing element (or “seal”), such as rubber, are subject to a temporary factor. In particular, with prolonged use, the seal is malfunctioning and requires replacement. However, it takes a lot of time to find a specific sealant, which complicates the installation and dismantling of valves from an economic point of view.

The closest analogue, in addition to the disadvantages mentioned above, has several more. In particular, to fix the throttle washer, an additional element is used - a tightening nut used to fix the washer inside the valve body, namely the pipe. The use of an additional element complicates the design of the reinforcement as a whole, as well as its assembly. In addition, there is a possibility of deformation of the nut, for example, compression, deflection, under the action of the force exerted to install a tightening nut inside the housing.

Utility Model Implementation

In FIG. 1 presents the basic elements of one embodiment of the proposed utility model, and a nominal wedge gate valve, and in FIG. 2 shows a local view of a longitudinal section of the outlet pipe in the assembly.

Said wedge gate valve (or “manual valve”) comprises a housing (1) including an inlet pipe (2) and an output pipe (3). Threads (4) and (5) are made on a part of the inner surface of each of the nozzles (2) and (3): the inlet pipe (2) contains an internal thread (4), and the outlet pipe (3) contains an internal thread (5).

Between the inlet pipe (2) and the outlet pipe (3), a shutter and a kinematic element are located (installed). The movable shutter member is made in the form of a wedge (6), and the fixed one in the form of a saddle (7).

Said kinematic element is fixed inside the housing (1) by means of a threaded connection, connected to an actuator made in the form of a cap (8), as well as to a shutter (6). In this example implementation of the proposed utility model, the kinematic element is made in the form of a non-retractable spindle known from the prior art (9). The spindle (9) is rigidly connected to the cap (8), and to the valve (6) is connected using a thread.

The valve assembly further comprises a throttle washer (10) located in the outlet pipe (3). The throttle washer (10) has the shape of a glass, and to simplify its installation and increase the reliability and tightness of its connection with the housing (1), it contains an external thread (11) made with the possibility of interaction (connection) with the internal thread (5) on a part of its side surface ) outlet pipe (3). The throttle washer (10) also includes at least one through reduction hole (12), the axis of which is located along the movement of the medium flow, and its center is on the periphery, i.e. located far from the center of the puck (10). On the side opposite to the direction of flow, the washer (10) further comprises means for simplifying its installation inside the outlet pipe (3), which is a groove (13) containing a cross slot.

In addition, the reinforcement further comprises a connecting element (14) connected to the inlet pipe (3) by means of a tightening nut (15).

Said connecting element (14) has the form of a hollow cylinder with an internal through hole. The outer surface of the connecting element (14) is conditionally divided into three sections: the first section, the second section, the third section. The first section contains a rounded protrusion (16) and is located closer to the end of the connecting element (14). The third section contains a means of connecting with external objects, made in the form of a thread, located closer to the end of the connecting element (14), which is opposite to the protrusion (16) and intended for connection with a pipe or with another threaded element and / or part, for example, known from the level fitting technology. The second section is an intermediate section between the first and third sections.

Said tightening nut (15) is made in the form of a cylinder with a through axial longitudinal hole (hollow cylinder). The surface of the inner hole of the tightening nut (15) is divided into two sections. The first section contains a thread (17) made with the possibility of connection with an external thread (18) made on a part of the outer surface of the outlet pipe (3). The second section contains a protrusion (19) directed to the longitudinal axis of the tightening nut (15). The diameter of the hole formed by said protrusion (19) is smaller than the diameter at the extreme point of the protrusion (16) of the connecting element (14), but larger than the diameter at the extreme point of the third portion of the connecting element (14). The outer surface of the tightening nut (15) is made with the possibility of connection with a wrench known from the prior art, i.e. the outer surface of the tightening nut (15) is made under the prior art wrench.

The outlet pipe (3) at the end of the internal through hole contains a chamfer (19), while its surface shape coincides with the surface shape of the protrusion (16) of the connecting element (14) at the point of their connection, or, in other words, the connecting element (14) repeats the shape of the outlet pipe (3) at their junction.

An exemplary embodiment of the proposed utility model is collected as follows.

The throttle washer (10) is screwed into the outlet pipe (3) by means of a groove (13) and a Phillips screwdriver, while the internal thread (6) of the outlet pipe (3) interacts with the external thread (11) of the washer (10), forming a tight connection. To prevent deformation of the washer (10), namely its thread (11), a protrusion (20) is additionally made on the inner surface of the outlet groove, which prevents the washer (10) from moving deeper into the outlet pipe (3). To simplify removing the washer (10) from the outlet pipe (3), a groove (13) and a screwdriver are also used.

The method of connecting the throttle washer (10) and the valve body (1) described above can significantly simplify the installation and dismantling of the throttle plate (10) in the valve body (1), and also eliminates the use of additional retaining elements, for example, tightening nuts, such as in the nearest analogue and / or additional seal, for example, in the form of a rubber ring. In addition, the probability of deformation of the washer (10) and / or body (1) of the valve during installation or removal is reduced.

Then, the connecting element (14) is inserted into the outlet pipe (3). The protrusion (16) prevents the further movement of the connecting element (14) inside the housing (1). Next, put a tightening nut (15) on the connecting element (14) and connect it to the outlet pipe (3) of the housing (1) by means of a thread (11) and a thread (17) using a wrench. The protrusion (19) presses the connecting element (14) against the valve body (1). At the junction of the connecting element (14) and the outlet pipe (3), a sealed connection is formed.

An exemplary embodiment of the proposed utility model is installed in the system by means of the thread (4) of the inlet pipe (2) and the third section of the connecting element (14).

An exemplary version of the proposed utility model works as follows.

The fittings can be in two positions: open and closed.

In the closed position, the shutter (6) is hermetically connected to the seat (7).

In the open position, the reinforcement is transferred by rotating the cap (8), which in turn rotates the spindle (9). The damper (6) moves up the spindle (9) by threading it to the required level or to the stop (not shown in the figures) and perpendicular to the axis of the flow of the working medium, connecting the outlet pipe (2) and the outlet pipe (3) and increasing the bore fittings. The maximum flow of the working fluid passing through the valve is determined by the throttle washer (10), namely by its parameters such as the number and size of the holes, and / or the dimensions of the passage section of the valve. For clarity, if the area of the passage section exceeds the area of the passage section formed by the set of passage sections of all holes (11), then the maximum flow of the working medium passing through the valve is limited by the throttle washer (10). If the area of the bore is smaller than the area of the bore formed by the set of bore all the openings (11), then the maximum flow of the working medium passing through the valve is limited by the bore formed by the valve (6).

By rotating the cap (8) in the opposite direction, the passage section of the valve is reduced: the shutter (6) moves down the spindle (9) and perpendicular to the axis of the flow of the working medium.

An exemplary version of the proposed utility model can be used to balance water supply systems and single-pipe and / or two-pipe heating systems by limiting the maximum flow of the working medium passing through the valve.

The tight connection of the valve (6) and seat (7) causes the valve to move to the closed position.

The above description with reference to the figures of the drawings of one of the embodiments of the proposed utility model is presented as an example and cannot be considered as a limitation. Other embodiments of the various features of the utility model formula, which determines the scope of the requested legal protection, are obvious to the specialist in the field of technology.

In FIG. 3 is a partial cross-sectional view with an alternative embodiment of the connecting element (14). An alternative embodiment of the connecting element (14) from the end in the first section in front of the protrusion (16) further comprises a protrusion directed along the longitudinal axis of the connecting element and forming a groove (21) for placing a sealing element (22) on it, for example, made in the form of rubber rings. The sealing element (22) is designed to additionally seal the connection of an alternative embodiment of the connecting element (14) and the valve body (1), is located during assembly of the valve between the alternative embodiment of the connecting element (14) and the walls of the outlet pipe (3) and can be any a prior art device. In other words, between an alternative embodiment of the connecting element (14) and the valve body (1). As noted earlier, the sealing element (22), made in the form of a rubber ring, is intended, in particular, for additional sealing of the connection and in other embodiments of the reinforcement, it may be absent or their number may be more than one.

As noted above, the throttle washer (10) may have at least one pressure reducing hole (12), the center of which is offset from the center of the throttle washer (10) and placed on the periphery. Moreover, in one embodiment, the throttle washer may have several (from two or more) pressure reducing holes (12), the longitudinal axes of which are equidistant from the longitudinal axis of the throttle washer (10). In addition, the longitudinal axis of the pressure reducing holes (12) can be both parallel to the longitudinal axis of the throttle washer (10), and can be located at an angle to it. The number of pressure reducing holes (12) is selected as necessary, in particular to limit the maximum flow of the working medium passing through the valve when the movable shutter element is fully open. There are also no restrictions on the shapes of the holes: they can have a constant passage area, or the mentioned area can vary. It is also obvious that throttle washers (10) can be more than one - a block (a set of throttle washers). In FIG. 4, 5, 6, 7, 8, 9, embodiments of the throttle washer are presented. In FIG. 4A shows a throttle washer (10) containing one hole (12), and FIG. 4B is a sectional view of the throttle washer (10) shown in FIG. 4A. In FIG. 5A shows a throttle washer (10) containing two holes (12), and FIG. 5B is a cross-sectional view of the throttle washer (10) shown in FIG. 5A. In FIG. 6A shows a throttle washer (10) containing three holes (12), and FIG. 6B is a cross-sectional view of the throttle washer (10) shown in FIG. 6A. In FIG. 7A shows a throttle washer (10) containing four holes (12), and FIG. 7B is a sectional view of the throttle washer (10) shown in FIG. 7A. In FIG. 8A shows a throttle washer (10) containing five holes (12), and FIG. 8B is a sectional view of the throttle washer (10) shown in FIG. 8A. In FIG. 9A shows a throttle washer (10) containing six holes (12), and FIG. 9B is a cross-sectional view of the throttle washer (10) shown in FIG. 9A.

In the example described above, the throttle washer (10) contained a means of simplifying its installation inside the nozzle, which is a groove (13). Obviously, in other embodiments, the aforementioned simplification means may constructively be a protrusion or recess. Said protrusion and recess may further include at least one slot and / or at least one specially formed groove known in the art. If necessary, said simplification means may not be available. In addition, in an exemplary embodiment of the proposed utility model, a means of simplifying the installation of the throttle washer (10) was installed from the side opposite to the direction of flow of the working medium (the base of the glass from its inner side). Obviously, in other implementations, said means of simplifying the installation of the throttle washer can be installed on any convenient side of the throttle washer (10), for example.

In the previously described example, the throttle washer (10) was installed inside the housing (1), namely in the outlet pipe (3), by a threaded connection. In other implementations, the throttle washer (10) can be installed inside the housing (1), namely in the inlet pipe (2), or both in the inlet pipe (2) and in the outlet pipe (3) at the same time. Thus, at least one pipe (2) and / or (3) must be configured to install at least one throttle washer (10).

In an exemplary embodiment of the proposed utility model, the protrusion (16) was rounded. Obviously, the aforementioned shape of the protrusion (16) is an example, but not a limitation. Other forms of protrusion (16) are obvious to a person skilled in the art. It is also obvious that in other embodiments of the proposed utility model, the protrusion (20) may be absent.

In the above example, a valve known from the prior art was used as a valve. It is obvious that various types, types and varieties of valves known from the prior art can be used as valves, for example, valves, cranes, and butterfly valves can be used. As an example, but not limited to the quality of valves, ball valves, various valves, thermostatic valves, regulators, etc. can be used. For example, in FIG. 10 shows a longitudinal section of a ball valve. Said ball valve comprises a housing (1), an inlet pipe (2) and an outlet pipe (3), on the inner surfaces of which threads (4) and (5) are made, respectively. The movable shutter element is made in the form of a ball plug (23) and two saddles (7), made in the form of o-rings. A spindle (9) is used as a kinematic element, which can be connected to a drive made in the form of a cap (8) using a fastener (not shown in Fig. 10) known from the prior art, for example, a screw. The cap (8) is connected to the housing (1) by an internal thread connected to a thread made on the outer surface of the housing (1). With the inlet pipe (2) and / or the output pipe (3), the washer (10) described above and the connecting element (14) can be connected via the above-described actions and material and technical means.

The proposed device can be made in the form of a thermostatic valve known from the prior art. In FIG. 11 is a longitudinal section of a thermostatic valve. Said thermostatic valve comprises a housing (1), an inlet pipe (2) and an outlet pipe (3), on the inner surfaces of which threads (4) and (5) are made, respectively. The kinematic element of the shutter is made in the form of a rod (24), and its movable element is in the form of a spool (25). The cap (8) is connected to the housing (1) by an internal thread connected to a thread made on the outer surface of the housing (1). With the inlet pipe (2) and / or the output pipe (3), the washer (10) described above and the connecting element (14) can be connected via the above-described actions and material and technical means.

It will be apparent to those skilled in the art that the movable shutter member may be provided with a locking member and / or control member known in the art.

In the presented examples of fittings, a cap (8) was used as a device designed to move the movable shutter element. It will be apparent to those skilled in the art that, as a device for moving a movable shutter member (locking and / or adjusting member), any actuator, actuator, or sensing member, or various combinations thereof, can be used.

In the above example, the third portion of the connecting element (14) contained a thread for connection with external objects, in particular, with pipes. Obviously, the third section of the connecting element (14) is designed to connect with the elements of the system and can be made with the possibility of connecting with them by methods known from the prior art. It is also obvious that said thread may be located on the inner surface of the connecting element. The connecting element (14) contains at least one known from the prior art means of connection with external objects (in particular, with parts, devices, elements, etc. of the system) with which establish a detachable and / or one-piece connection with the elements and / or parts of a system, in particular with an external pipe, flange, fitting intended for connection to pipelines, and / or fittings known from the prior art. As such means of connection with external objects can be threads, flanges, sockets for welding, etc.

Obviously, there can be more than one connecting element (14). Thus, at least one pipe (2) and / or (3) can be made with the possibility of connection with a tightening nut (15) of the connecting element (14).

The internal threads (4) and / or (5) of the nozzles (2) and / or (3) can be designed to be connected to at least one throttle washer (10). It is also obvious that the internal threads (4) and / or (5) can be made with the possibility of connection with external elements, for example, elements of the system into which the valve is installed. It is obvious that for connection with the system only on the outer surface of the pipe (2) and / or (3) can be made thread for connection with the elements of the system. Thus, the nozzles (2) and (3) contain means for connecting to the system elements, made in the form of external and / or internal threads, which, if necessary, can be used to connect with at least one throttle washer (10) and / or at least at least one tightening nut (15) used to connect the connecting element (14) and the valve body (1).

Obviously, a valve, an actuator, an actuator or a sensing element, or various combinations thereof, can be used to control valves. It is also obvious that, if necessary, the spindle (9) can be made non-extendable or extendable.

The proposed utility model is a reinforcement that can be used both in a single-pipe system and / or in a two-pipe system and other systems. In other words, the proposed device is a universal device containing a universal connection.

The proposed device can be completely or part of its elements made of stainless steel or other material.

Under the "system" refers to the pipeline system or various containers, in / on which can be installed fittings.

By “working medium” is meant, for example, liquid, gaseous, gas-liquid, powder, etc. medium or suspension.

Thus, in the proposed utility model, the design and use of pipe fittings and connections with external objects known from the prior art have been eliminated, in particular, mounting the valves to the system and dismantling from it has been simplified while maintaining the tightness and integrity of the connected valves. In addition, the proposed new design of the connecting element does not limit its use in any one type (type, etc.) of pipe fittings - the universality of the connecting element - and its reliability is increased. Using the proposed utility model in industry allows balancing the heating system, cold and hot water supply, as well as restricting the flow of the working medium through the valve to achieve other goals.
