Description

Technical Field

[0001] This utility model belongs to the field of regulating valve technology, and specifically relates to an anti-detachment regulating valve cover assembly. Background Technology

[0002] Control valves are core components in industrial automation control used to regulate parameters such as flow rate, pressure, and temperature of media. Control signals drive the actuator, which in turn moves the valve core, adjusting the valve opening and thus changing the flow resistance of the media to regulate parameters such as flow rate and pressure.

[0003] In existing technologies, the valve cover is usually fixed to the valve body by bolts or clamps. However, when used for a long time in high temperature, high pressure or vibration environments, the bolts are prone to loosening and the clamps are prone to fatigue fracture, which can easily cause the valve cover to fall off and thus cause leakage of the conveyed medium. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes an anti-detachment regulating valve cover assembly to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an anti-detachment type regulating valve cover assembly, including a valve body:

[0007] The valve body is respectively provided with a sealing component, a fixing component, a limiting component and a snap-fit ​​component;

[0008] The sealing assembly has its bottom end fitted against the top end of the valve body so that the sealing assembly seals the top end of the valve body;

[0009] The bottom end of the fixing component is abutted against the top end of the sealing component, so that the fixing component limits and fixes the sealing component.

[0010] The limiting component has its movable end fixedly connected to one side of the snap-fit ​​component, so that the limiting component restricts the position of the snap-fit ​​component;

[0011] The snap-fit ​​assembly has its top end fixedly connected to the bottom end of the sealing assembly, so that the snap-fit ​​assembly snaps and fixes the sealing assembly.

[0012] Furthermore, the sealing assembly includes a sealing groove, which is formed at the top of the valve body. A sealing cylinder is slidably disposed inside the sealing groove, and a valve cover is fixedly connected to the top of the sealing cylinder.

[0013] Furthermore, the fixing component includes a threaded hole, which is opened at the top of the valve body. A stud is threadedly connected inside the threaded hole, and a fixing nut is threadedly connected to the threaded surface of the stud. The bottom end of the fixing nut is in contact with the top end of the valve cover.

[0014] Furthermore, the limiting component includes a sliding groove, which is formed inside the valve body. A lead screw is threaded into the sliding groove, and a rotating handle is fixedly connected to one end of the lead screw.

[0015] Furthermore, the limiting component also includes a limiting cylinder, the limiting cylinder having a limiting groove inside, and a rotating seat being slidably disposed inside the limiting groove, the rotating seat being rotatably disposed with respect to the outer surface of the lead screw.

[0016] Furthermore, the snap-fit ​​assembly includes a spring, one end of which is fixedly connected to the inner wall of the sliding groove, and the other end of which is fixedly connected to a first wedge, one side of which is fixedly connected to one end of the limiting cylinder.

[0017] Furthermore, the snap-fit ​​assembly also includes a second wedge, the top end of which is fixedly connected to the bottom end of the valve cover, and a snap-fit ​​groove is provided on one side of the second wedge, the interior of which is snap-fitted to the outer surface of the first wedge.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model inserts the sealing component into the valve body, causing it to drive the snap-fit ​​component fixed at the bottom to be inserted into the limiting component. Then, the limiting component is rotated, causing it to drive the snap-fit ​​component fixed at one end to move, thereby enabling the snap-fit ​​component to complete the snap-fit ​​setting, thus restricting the sealing component and preventing the sealing component from falling off the valve body, thus avoiding leakage of the conveying medium.

[0020] 2. In this utility model, when the valve cover drives the second wedge to insert into the sliding groove, its bottom wedge surface fits against the top wedge surface of the first wedge. Thus, with the continuous movement of the second wedge, the first wedge can be pushed to move. When the second wedge moves to the bottom of the sliding groove, it can drive the snap-fit ​​groove opened on one side to move to the side of the first wedge, thereby releasing the spring force and pushing the first wedge into the snap-fit ​​groove. Then, the screw is rotated to drive the rotating seat rotatably set on its outer surface to move to the other end of the limiting groove, so as to restrict the limiting cylinder. Thus, it works with the first wedge to restrict the second wedge, so as to prevent the valve cover fixed at its top from falling off.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0033] Please see Figures 1-6 As shown, this utility model is an anti-detachment type regulating valve cover assembly, including valve body 1:

[0034] The valve body 1 is respectively provided with a sealing component 2, a fixing component 3, a limiting component 4, and a snap-fit ​​component 5;

[0035] The sealing assembly 2 has its bottom end fitted against the top end of the valve body 1 so that the sealing assembly 2 seals the top end of the valve body 1.

[0036] The bottom end of the fixing component 3 is attached to the top end of the sealing component 2 so that the fixing component 3 limits and fixes the sealing component 2.

[0037] The moving end of the limiting component 4 is fixedly connected to one side of the snap-fit ​​component 5 so that the limiting component 4 restricts the position of the snap-fit ​​component 5.

[0038] The top end of the snap-fit ​​component 5 is fixedly connected to the bottom end of the sealing component 2 so that the snap-fit ​​component 5 snaps and fixes the sealing component 2.

[0039] In use, the sealing component 2 is inserted into the valve body 1, and then the sealing component 3 is used to seal the sealing component 2 and the valve body 1. When the sealing component 2 is inserted into the valve body 1, it can drive the snap-fit ​​component 5 fixed at its bottom end to be inserted into the limit component 4. Then, the limit component 4 is rotated, which drives the snap-fit ​​component 5 fixed at one end to move, and at the same time, the snap-fit ​​component 5 completes the snap-fit ​​setting, thereby restricting the sealing component 2.

[0040] This invention inserts the sealing component 2 into the valve body 1, causing it to drive the snap-fit ​​component 5 fixed at the bottom to be inserted into the limiting component 4. Then, the limiting component 4 is rotated, causing it to drive the snap-fit ​​component 5 fixed at one end to move, thereby enabling the snap-fit ​​component 5 to complete the snap-fit ​​setting, thus restricting the sealing component 2 and preventing the sealing component 2 from falling off the valve body 1, thus avoiding leakage of the conveying medium.

[0041] In one embodiment, the sealing assembly 2 includes a sealing groove 201, which is formed at the top of the valve body 1. A sealing cylinder 202 is slidably disposed inside the sealing groove 201, and a valve cover 203 is fixedly connected to the top of the sealing cylinder 202.

[0042] The valve cover 203 is used to move the sealing cylinder 202, which is fixed at the bottom, into the sealing groove 201 so that the bottom of the valve cover 203 fits against the top of the valve body 1.

[0043] In one embodiment, the fixing component 3 includes a threaded hole 301, which is located at the top of the valve body 1. A stud 302 is threadedly connected to the inside of the threaded hole 301, and a fixing nut 303 is threadedly connected to the threaded surface of the stud 302. The bottom end of the fixing nut 303 is in contact with the top end of the valve cover 203.

[0044] By screwing the stud 302 into the threaded hole 301, and then having the bottom end of the valve cover 203 fit against the top end of the valve body 1, the stud 302 penetrates the interior of the valve cover 203. Then, the internal thread of the fixing nut 303 engages with the stud 302, causing the fixing nut 303 to move downward along the direction of the stud 302, so that its bottom end fits against the top end of the valve cover 203, thereby sealing the valve cover 203 and the valve body 1.

[0045] In one embodiment, the limiting component 4 includes a sliding groove 401, which is formed inside the valve body 1. A lead screw 402 is threadedly connected inside the sliding groove 401, and a handle 403 is fixedly connected to one end of the lead screw 402.

[0046] The limiting component 4 also includes a limiting cylinder 404, the limiting cylinder 404 has a limiting groove 405 inside, and a rotating seat 406 is slidably disposed inside the limiting groove 405. The interior of the rotating seat 406 is rotatably disposed with respect to the outer surface of the lead screw 402.

[0047] The rotating handle 403 drives the screw 402, which is fixed on one side, to rotate, so that it moves in conjunction with the internal thread of the sliding groove 401. This causes the rotating seat 406, which is rotatably mounted on its outer surface, to move. The rotating seat 406 moves along the direction of the limiting groove 405 inside the limiting cylinder 404. Since the length of the limiting cylinder 404 is fixed and the limiting groove 405 inside it can limit the moving distance of the rotating seat 406, when the rotating seat 406 moves to one end of the limiting groove 405, it can drive the limiting cylinder 404 to move. When the rotating seat 406 moves to the other end of the limiting groove 405, it can drive the limiting cylinder 404 to move in the opposite direction.

[0048] In one embodiment, the snap-fit ​​assembly 5 includes a spring 501, one end of which is fixedly connected to the inner wall of the sliding groove 401, and the other end of which is fixedly connected to a first wedge 502, one side of which is fixedly connected to one end of the limiting cylinder 404.

[0049] The snap-fit ​​assembly 5 also includes a second wedge 503, the top end of which is fixedly connected to the bottom end of the valve cover 203, and a snap-fit ​​groove 504 is provided on one side of the second wedge 503, the interior of which is snap-fitted to the outer surface of the first wedge 502.

[0050] When the rotating seat 406 is at one end of the limiting groove 405, as the valve cover 203 drives the second wedge 503 to insert into the sliding groove 401, its bottom wedge surface comes into contact with the top wedge surface of the first wedge 502. Thus, with the continuous movement of the second wedge 503, the first wedge 502 can be pushed to move, compressing the spring 501 fixed on one side. Simultaneously, it can drive the limiting cylinder 404 fixed on one side to move, thereby causing the limiting cylinder 404 to move along the direction of the rotating seat 406 in conjunction with the limiting groove 405. When the wedge 503 moves to the bottom of the sliding groove 401, it can drive the snap-fit ​​groove 504 opened on one side to move to the side of the first wedge 502. Then the elastic force of the spring 501 is released, which pushes the first wedge 502 into the interior of the snap-fit ​​groove 504. Then the screw 402 is rotated to drive the rotating seat 406 rotatably set on its outer surface to move to the other end of the limiting groove 405, so that it restricts the limiting cylinder 404, thereby cooperating with the first wedge 502 to restrict the second wedge 503, so as to prevent the valve cover 203 fixed at its top from falling off.

[0051] Through the above technical solution, 1. By inserting the sealing component 2 into the interior of the valve body 1, it drives the snap-fit ​​component 5 fixed at the bottom to be inserted into the interior of the limiting component 4. Then, by rotating the limiting component 4, it drives the snap-fit ​​component 5 fixed at one end to move, and at the same time, the snap-fit ​​component 5 completes the snap-fit ​​setting, thereby restricting the sealing component 2, thereby preventing the sealing component 2 from falling off the valve body 1 and avoiding leakage of the conveying medium.

[0052] 2. When the valve cover 203 drives the second wedge 503 to insert into the sliding groove 401, its bottom wedge surface is in contact with the top wedge surface of the first wedge 502. Thus, with the continuous movement of the second wedge 503, the first wedge 502 can be pushed to move. When the second wedge 503 moves to the bottom of the sliding groove 401, it can drive the snap-fit ​​groove 504 opened on one side to move to the side of the first wedge 502. Then, the elastic force of the spring 501 is released, which pushes the first wedge 502 into the interior of the snap-fit ​​groove 504. Then, the screw 402 is rotated to drive the rotating seat 406 rotatably set on its outer surface to move to the other end of the limiting groove 405, so as to restrict the limiting cylinder 404. Thus, it cooperates with the first wedge 502 to restrict the second wedge 503, so as to prevent the valve cover 203 fixed at its top from falling off.
