Description

Fluid flow control valve{VALVE}

The present disclosure relates to a fluid flow control valve.

Typically, valves are installed on the pipeline to control the flow of fluid. The valves control the flow of fluid so that the fluid flowing in one direction along the pipeline is diverged into multiple branch pipes connected to the pipeline.

For example, in the case of a pipe having two branch pipes, a 3-way valve can be installed. The 3-way valve is a structure having three connection ports communicating with the pipe and each branch pipe, and switches the flow of fluid flowing into the pipe to each branch pipe or blocks the flow of the flow path.

These valves require a complex structure and a large number of parts to control the flow of fluid. Therefore, they take a lot of time to assemble and are difficult to miniaturize, which increases the overall size. In addition, the valves are difficult and inconvenient to operate, and it is not easy to check the valve status inside the pipe, which makes them inconvenient to use.

Therefore, providing an improvement over the problems of conventional valves can provide many advantages to users.

The objective of this project is to provide a fluid flow control valve that is simple in configuration and easy to assemble by minimizing the number of parts used.

The present invention aims to provide a fluid flow control valve that is easier to use.

The present task is to provide a fluid flow control valve capable of effectively checking the operating status of the valve.

The present invention relates to a fluid flow control valve capable of minimizing wear of an O-ring on the inner surface of a rough valve.

The valve of the present embodiment may be a fluid flow control valve installed in a pipe body having at least one branch pipe provided on the pipe body, and controlling the flow of fluid introduced along the pipe body for each branch pipe.

The above fluid flow control valve may include a rotating body that is rotatably installed and inserted into the inner surface of a pipe of the pipe body and has an inner end that is open to communicate with the pipe of the pipe body and has an outlet formed on the outer surface of the rotating body at a position corresponding to a branch pipe formed in the pipe body; a first O-ring that is installed along the outer surface of one side of the rotating body to maintain an airtight seal between the inner surface of the pipe and the rotating body; a second O-ring that is installed along the periphery of the outlet on the outer surface of the rotating body; an internal step formed inside the pipe body to limit the position of the inner end of the rotating body; a stopper ring that is detachably fitted into an inner groove formed along the inner surface of the pipe end to prevent the rotating body from detaching and to allow the outer end of the rotating body to be caught; a lever that is formed to extend outwardly along the axial direction at the center of the end of the rotating body; and a rotating knob that is coupled to the lever to rotate the rotating body.

The above rotary knob may have a groove formed on the inside into which the lever is fitted, the lever and the groove formed into a polygonal cross-section and interlocked with each other, and the tip of the rotary knob may have a structure in which a hook is formed and interlocked with a catch formed along the outer circumference of the tip of the pipe and fixed.

The invention may further include a regulating member installed between the above-described body and the above-described rotating body to regulate rotation of the above-described rotating body.

The above-mentioned regulatory member may include at least one or more ribs formed along the inner surface of the body, and an iron part formed on the outer surface of the rotating body at a position corresponding to the ribs and interlocked with the ribs.

The above rotary knob may have a structure in which a display portion is formed on the outer surface in accordance with the position of the discharge port formed on the above rotary body to indicate the position of the discharge port of the rotary knob to the outside.

The above fluid flow control valve may further include a fixed body fixedly installed to the pipe body and inserted between the pipe body and the rotating body.

The fluid flow control valve comprises: a fixed body inserted and fixedly installed into the inner surface of the pipe of the pipe body and having both ends open to communicate with the pipe of the pipe body and having an outlet formed on the outer surface at a position corresponding to a branch pipe formed in the pipe body; a rotating body inserted and rotatably installed into the inner surface of the fixed body and having an inner end open to communicate with the pipe of the pipe body and having an outlet formed on the outer surface at a position corresponding to the outlet of the fixed body; a first O-ring installed along the outer surface of one side of the rotating body to maintain airtightness between the rotating body and the fixed body; a second O-ring installed along the periphery of the discharge port on the outer surface of the rotating body; a third O-ring installed along the outer surface of one side of the fixed body to maintain airtightness between the fixed body and the pipe body; a fourth O-ring installed along the periphery of the outlet on the outer surface of the fixed body; an internal step formed inside the pipe body to limit the position of the inner end of the fixed body; a removably fitted inner groove formed along the inner surface of the pipe end to prevent the detachment of the rotating body; It may include a stopper ring that catches the outer end of the rotating body, a lever that extends outwardly along the axial direction at the center of the end of the rotating body, and a rotation knob that is coupled to the lever and rotates the rotating body.

The inner diameter of the inner step has a polygonal cross-section, and the fixed body may have a structure in which a polygonal cross-section fitting part is formed on the inner end to fit into the inner step, and is fixed so as to limit rotation with respect to the pipe body.

Hereinafter, embodiments of the present invention will be described in detail. However, these are presented as examples, and the present invention is not limited thereby, and the present invention is defined only by the scope of the claims described below. The embodiments described below can be modified in various forms without departing from the concept and scope of the present invention. Where possible, identical or similar parts are indicated using the same reference numerals in the drawings.

The terminology used below is for the purpose of describing specific embodiments only and is not intended to limit the invention. The singular forms used herein include the plural forms as well, unless the context clearly dictates otherwise. The word "comprising," as used in the specification, specifies particular features, regions, integers, steps, operations, elements, and/or components, but does not exclude the presence or addition of other particular features, regions, integers, steps, operations, elements, components, and/or groups.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the following embodiments are only preferred embodiments of the present invention, and the present invention is not limited to the following embodiments.

Figure 1 shows a state in which a fluid flow control valve according to the present embodiment is assembled into a pipe body.

As illustrated in FIG. 1, the fluid flow control valve (10) (hereinafter referred to as valve) of the present embodiment is described as an example of a three-way valve structure installed in a pipe body (20) in which two branch pipes (22, 24) are arranged at a 90-degree angle on a pipe.

The term body (20) may refer to a body forming the outer shape of the valve (10). In the case of this structure, the valve (10) of the present embodiment is configured to include the body (20), and may be provided separately from the pipe and installed in connection with the pipe.

Unlike the above structure, the pipe body (20) may refer to a pipe in which a valve (10) is installed. In the case of this structure, the valve (10) may be installed directly inside the pipe body (20), which is a pipe.

For the convenience of the following explanation, the two branch pipes are referred to as the first branch pipe (22) and the second branch pipe (24), respectively, and the term “branch pipes (22, 24)” may refer to both the first branch pipe (22) and the second branch pipe (24). In addition, the x-axis direction in Fig. 1 is referred to as the axial direction.

The present invention is not limited thereto, and can be applied to all fluid flow control of a pipe body having one or three or more branch pipes and arranged at various angles.

As shown in Fig. 1, the valve (10) is installed at the tip of the pipe (20).

As mentioned, the body (20) may refer to a pipe, and may refer to a body that is a component of a valve (10).

A rotary knob (50) is placed on the outside of the pipe body (20), so that the operator can simply control the flow of fluid by distributing or blocking the fluid flowing into the pipe of the pipe body (20) to each branch pipe by rotating the rotary knob (50).

The rotary knob (50) may have an inwardly sunken marking portion (52) formed on the outer surface according to the number and formation angle of each branch pipe. This marking portion (52) indicates the position of the outlet of the valve (10) formed according to the position of the branch pipe. Accordingly, the worker can easily check the position of the outlet, which is located inside the pipe body (20) and cannot be seen from the outside, through the marking portion (52) formed on the rotary knob (50). This structure will be described in detail later.

Figures 2 and 3 illustrate a valve according to the first embodiment.

As illustrated, the valve (10) according to the present embodiment may include a rotating body (30) installed in a pipe (20) to control the fluid flow, a first O-ring and a second O-ring (34) for maintaining sealing, a stopper ring (40) for preventing the rotating body (30) from detaching, and a lever and a rotating knob (50) for driving the rotation of the rotating body (30).

The rotating body (30) is cylindrical and is installed rotatably by being inserted into the inner surface of the pipe of the tube (20). The outer end of the rotating body (30) is closed, and the inner end is open so as to communicate with the pipe of the tube (20). On the outer surface of the rotating body (30), discharge ports (31, 32) are formed at positions corresponding to each branch pipe formed in the tube (20). Drawing symbol (25) is a hole formed in the tube (20) so as to communicate with the branch pipe (22, 24). In the following description, the branch pipe (22, 24) means the hole (25), and opening and closing the branch pipe can be understood as opening and closing the hole.

Hereinafter, in a state where each branch pipe and outlet are aligned, the outlets corresponding to the first branch pipe (22) and the second branch pipe (24) are referred to as the first outlet (31) and the second outlet (32), respectively. The terms outlets (31, 32) may refer to both the first outlet (31) and the second outlet (32).

Accordingly, when the rotating body (30) rotates inside the pipe body (20), the position of each outlet and the position of each branch pipe of the pipe body (20) are opened or closed while matching or misaligning with each other, thereby controlling the flow of the flow path.

The rotating body (30) has an O-ring installed on the outer surface to maintain sealing with the pipe (20). The rotating body (30) of the present embodiment may include a first O-ring (33) installed along the outer surface and a second O-ring (34) installed along the periphery of the discharge port. A groove may be formed on the outer surface of the rotating body (30) in which the O-ring is seated according to the installation positions of the first O-ring (33) and the second O-ring (34).

The first O-ring (33) seals between the inner surface of the rotor (30) and the pipe body (20) to prevent fluid from flowing out of the pipe body (20). The second O-ring (34) seals around the discharge port to prevent fluid passing through the discharge port from flowing out between the rotor (30) and the inner surface of the pipe body (20) at the discharge port.

The rotating body (30) is installed between the internal step (26) formed inside the tube body (20) and the stopper ring (40). The internal step (26) and the stopper ring (40) limit the axial movement of the rotating body (30). Accordingly, the rotating body (30) is limited in its axial movement inside the tube body (20) and can only perform a rotational motion.

The inner step (26) limits the position of the inner end of the rotating body (30). The inner step (26) is formed to protrude inwardly from the inside of the tube (20) so that the inner diameter is smaller than the outer diameter of the rotating body (30). Accordingly, the inner end of the rotating body (30) is caught by the inner step (26) and does not move in the axial direction.

A stopper (40) is installed at the tip of the tube (20) to prevent the rotation body (30) from being detached.

An inner groove (27) is formed at the tip of the pipe body (20) along the inner surface so that a stopper ring (40) can be fitted therein. The stopper ring (40) may be, for example, a snap ring structure having a round shape with one side cut off. The stopper ring (40) protrudes from the inner surface of the pipe body (20) and catches and fixes the tip of the rotating body (30). In addition, if necessary, the fixation of the rotating body (30) can be simply released and disassembled by removing the stopper ring (40) from the inner groove (27) of the pipe body (20).

In this way, by installing the stopper (40) in the body (20), the rotating body (30) can be easily assembled and disassembled inside the body (20).

A lever (35) is installed at the outer tip of the rotating body (30). The lever (35) can be formed integrally with the rotating body (30). The lever (35) is formed to extend outward along the axial direction at the center of the tip of the rotating body (30).

The rotary knob (50) is connected to the rotary body (30) by being combined with the lever (35). A groove (54) is formed in the center of the inner side of the rotary knob (50) to engage with the lever (35).

The lever (35) is connected to the groove (54) of the rotary knob (50) to transmit the rotational power of the rotary knob (50) to the rotary body (30). The lever (35) and the groove (54) may be formed in a polygonal cross-sectional structure so that the rotational power can be accurately transmitted. In the present embodiment, the lever (35) and the groove (54) may be formed in a square cross-sectional shape.

Accordingly, when the rotary knob (50) is rotated, the lever (35) fitted into the groove (54) rotates together with the rotary knob (50), and the rotating body (30) on which the lever (35) is formed rotates relative to the tube (20), thereby controlling the flow of fluid.

The rotary knob (50) can be connected to the tip of the tube (20) by covering the lever (35). The rotary knob (50) may have a hook (56) formed at the tip and may be structured to be fixed by engaging with a catch (29) formed along the outer circumference of the tip of the tube (20). The rotary knob (50) may be formed of, for example, a resin material having its own elasticity. Accordingly, the hook (56) of the rotary knob (50) may be elastically spread and fitted into the catch (29) to be installed. Since the catch (29) is formed continuously in the circumferential direction, the rotary knob (50) can be rotated even when the hook (56) is caught on the catch (29) and assembled to the tube (20).

In this way, by simply fitting the hook (56) of the rotary knob (50) into the catch (29) at the tip of the body (20), the rotary knob (50) can be firmly assembled with the rotary body (30), and the rotary knob (50) can be easily rotated.

The rotary knob (50) is connected to the tip of the pipe body (20), thereby covering the rotary body (30) or lever (35) exposed to the tip of the pipe body (20), thereby protecting the valve (10) from the outside. In addition, when necessary, the rotary knob (50) can be simply separated from the catch (29) to perform tasks such as dismantling the valve (10).

In addition, as mentioned, the rotary knob (50) of the present embodiment may have a display portion (52) formed on the outer surface in accordance with the position of the discharge port formed in the rotating body (30). The display portion (52) indicates the position of the discharge port of the rotary knob (50) to the outside.

Accordingly, when the rotary knob (50) is rotated, the position of the indicator (52) can be checked to accurately determine the direction in which the current discharge port position inside the valve (10) is facing, whether it matches the branch pipe of the pipe (20), etc. Accordingly, the worker can easily check which branch pipe is open or closed by checking the position of the indicator (52) formed on the rotary knob (50) for the branch pipe installed in the pipe (20).

The valve (10) of the present embodiment may further include a regulating member installed between the tube (20) and the rotating body (30) to regulate the rotation of the rotating body (30). The regulating member prevents the rotating body (30) from easily rotating, thereby restricting the rotational state of the rotating body (30) from changing.

Accordingly, the state in which the rotating body (30) rotates and controls the fluid flow of the valve (10) can be stably maintained.

The regulatory member may include at least one yoke (28) formed along the inner surface of the pipe body (20), and an iron member (36) protrudingly formed on the outer surface of the rotating body (30) at a position corresponding to the yoke (28) and engaging with the yoke (28). For example, the yoke (28) may be formed at a 90-degree angle along the inner surface of the pipe body (20) to match the arrangement angle of each branch pipe formed in the pipe body (20).

Accordingly, when the rotating body (30) is rotated to a desired position, the protruding iron part (36) is inserted into the lower part (28) and interlocked with each other, so that the rotation of the rotating body (30) can be limited. Accordingly, the rotating body (30) can be rotated to an accurate position and fixed.

Meanwhile, FIGS. 4 and 5 illustrate another embodiment of the valve.

The valve (10) of this embodiment has a structure in which a fixed body (60) is additionally provided between the tube body (20) and the rotating body (30), and except for this structure, the other components are the same as those of the embodiment described above. Accordingly, the same components are described using the same drawing reference numerals, and a detailed description thereof is omitted.

Hereinafter, a valve (10) according to the second embodiment will be described with reference to FIGS. 4 and 5.

The valve (10) of the present embodiment may further include a fixed body (60) that is fixedly installed on the pipe body (20) and inserted between the pipe body (20) and the rotating body (30).

The fixture (60) is inserted into the inner surface of the pipe of the tube body (20) in a cylindrical shape and fixedly installed on the inside of the pipe. The fixture (60) has a structure in which both ends are open, and the inner end is connected to the pipe of the tube body (20). The rotating body (30) can be inserted and installed on the inside of the fixture (60) through the open outer end of the fixture (60).

On the outer surface of the fixed body (60), an outlet (61) is formed at a position corresponding to each branch pipe (22, 24) formed in the pipe body (20).

The fixture (60) has an O-ring installed on the outer surface to maintain sealing with the pipe (20). The fixture (60) of the present embodiment may include a third O-ring (62) installed along the outer surface and a fourth O-ring (63) installed along the periphery of the outlet (61). A groove may be formed on the outer surface of the fixture (60) in which the O-ring is seated according to the installation positions of the third O-ring (62) and the fourth O-ring (63).

The third O-ring (62) seals between the fixed body (60) and the pipe of the pipe body (20) to prevent the fluid from flowing out of the pipe body (20). The fourth O-ring (63) seals around the outlet (61) to prevent the fluid passing through the outlet (61) from flowing out between the fixed body (60) and the inner surface of the pipe body (20) at the outlet (61).

In this embodiment, the fixture (60) can be fixed by being fitted into the internal step (26) formed inside the pipe body (20). The fixture (60) can have a fitting portion (64) formed on the inner end to be fitted into the internal step (26). In addition, the fitting portion (64) is formed in a polygonal cross-section shape, and the inner surface of the internal step (26) into which the fitting portion (64) is inserted can also be formed in a polygonal cross-section shape corresponding to the fitting portion (64). Accordingly, when the fixture (60) is inserted into the pipe body (20), the end of the fixture (60) is caught on the internal step (26) and movement in the axial direction is restricted, and the fitting portion (64) is fitted on the internal step (26) and rotation is restricted.

Accordingly, the outlet (61) formed in the fixture (60) can be aligned with the branch pipe (22, 24) position of the pipe (20) so that the fixture (60) can be fixedly installed within the pipe (20).

In this embodiment, the fixture (60) can be injection-formed. Accordingly, the inner surface of the fixture (60) can be formed to be relatively very smooth compared to the inner surface of the tube (20).

Accordingly, wear or damage that occurs when the O-ring of the rotating body (30) rotating inside the fixed body (60) comes into contact with the inner surface of the fixed body (60) can be further reduced.

As is known, the pipe body (20) is manufactured by cutting the inner surface of a material such as brass to a desired diameter through a drilling process, etc. Accordingly, the inner surface of the pipe body (20) is not smooth but very rough. Accordingly, if an O-ring comes into direct contact with the inner surface of the pipe body (20), it can easily be worn or damaged.

In the present embodiment, a fixed body (60) that is injection-molded and has a smooth inner surface is provided within the tube (20), and as the rotating body (30) rotates while contacting the fixed body (60) rather than the tube (20), the O-ring of the rotating body (30) can be prevented from being easily worn or damaged. Accordingly, the life of the O-ring can be increased.

The rotating body (30) is formed with an outer diameter that can be installed inside the fixed body (60). The rotating body (30) is inserted into the inner surface of the fixed body (60) and installed so as to be rotatable. An outlet (31, 32) is formed on the outer surface of the rotating body (30) at a position corresponding to the outlet (61) of the fixed body (60).

The first O-ring (33) installed on the outer surface of the rotating body (30) seals between the rotating body (30) and the fixed body (60) to prevent fluid from flowing out to the outside of the pipe (20). The second O-ring (34) seals around the discharge port (31, 32) between the fixed body (60) and the rotating body (30), thereby preventing fluid passing through the discharge port from flowing out between the fixed body (60) and the inner surface of the pipe (20) at the discharge port.

The inner end of the rotating body (30) is fixed by being caught on the inner end of the fixed body (60), and the outer end is fixed by a stopper ring (40) so that movement in the axial direction is restricted.

A regulating member may be provided between the fixed body (60) and the rotating body (30) to regulate the rotation of the rotating body (30).

The regulatory member of the present embodiment may be formed between the contact surfaces of the fixed body (60) and the rotating body (30) that face each other along the axial direction. To this end, the regulatory member may include at least one yoke (65) formed along the outer edge of the fixed body (60), and an iron part (38) formed along the rotating body (30) at a position corresponding to the yoke (65) and interlocked with the yoke (65).

A flange (37) may be formed on the outer end of the rotating body (30) so as to be in contact with the end of the fixed body (60). In addition, a steel part (38) is formed to protrude from the flange (37) so as to face the yoke (65). For example, the yoke (28) may be formed to be arranged at a 90-degree angle along the end of the fixed body (60) in accordance with the arrangement angle of each branch pipe formed in the pipe body (20).

Accordingly, when the rotating body (30) rotates, the iron part (38) formed on the flange (37) moves and is inserted into and engaged with the yoke (65) formed on the tip of the fixed body (60), thereby restraining the rotation of the rotating body (30).

Below, the operation of this embodiment will be described with reference to Fig. 6.

The following description of the operation is given using a valve (10) having a fixed body (60) inside according to the second embodiment as an example.

As shown in Fig. 6, when the rotary knob (50) is turned, the rotary body (30) connected via the lever (35) rotates relative to the fixed body (60). As the rotary body (30) rotates, the first discharge port (31) and the second discharge port (32) formed in the rotary body (30) are connected to or blocked from the first branch pipe (22) and the second branch pipe (24) formed in the pipe (20).

As mentioned, the position of the outlet of the rotary body (30) matches the position of the indicator (52) formed on the rotary knob (50), so the position of the outlet can be accurately confirmed from the outside of the pipe (20) through the position of the indicator (52), thereby controlling the valve (10) to the desired flow.

As shown in Fig. 6, when the rotor (30) rotates so that the first discharge port (31) and the second discharge port (32) come to the positions of the first branch pipe (22) and the second branch pipe (24) formed in the pipe (20), both the first branch pipe (22) and the second branch pipe (24) are opened.

In this state, when the rotor (30) is rotated 90 degrees counterclockwise, the first branch pipe (22) is blocked by the rotor (30), and the first discharge port (31) of the rotor (30) moves to the position of the second branch pipe (24), so that only the second branch pipe (24) is opened.

Conversely, when the rotor (30) rotates 90 degrees clockwise, the second branch pipe (24) is blocked by the rotor (30) and the second discharge port (32) of the rotor (30) moves to the position of the first branch pipe (22), so that only the first branch pipe (22) is opened.

In addition, when the rotor (30) rotates 180 degrees, both the first discharge port (31) and the second discharge port (32) move out of the positions of the first branch pipe (22) and the second branch pipe (24), so that both the first branch pipe (22) and the second branch pipe (24) are blocked by the rotor (30), thereby blocking the fluid flow.

In this way, the valve (10) can be simply controlled by driving the rotary body (30) by rotating the rotary knob (50) in any direction with a simple structure.

While exemplary embodiments of the present invention have been illustrated and described above, it will be apparent to those skilled in the art that various modifications and other embodiments may be made thereto. It is intended that all such modifications and other embodiments be considered and encompassed by the appended claims and do not depart from the true spirit and scope of the present invention.
