Description

Technical Field

[0001] The utility model relates to the technical field of valve installation, in particular to a valve which is convenient to install. Background Technique

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters of the conveyed medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. A valve is a control component in a fluid conveying system and has functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, shunt or overflow pressure relief. Valves used in fluid control systems range from the simplest stop valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media.

[0003] When a valve is connected to a pipeline, most of them use the flange connection method. However, after long-term use, the flange connection method may leak water, which will cause the sealing performance between the valve and the pipeline to deteriorate, and then the leakage situation will become worse and worse. Therefore, a valve that is convenient to install is proposed to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a valve which is convenient to install, aiming to solve the problems put forward in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A valve which is convenient to install includes a valve body. An outer connecting pipe is arranged at one end of the valve body. A connecting component and a sealing component are arranged between the outer connecting pipe and the valve body. A sealing sleeve is sleeved at the connection between the outer connecting pipe and the valve body. A first clamping plate and a second clamping plate are respectively arranged above and below the sealing sleeve. Clamping grooves are respectively formed on the inner sides of the first clamping plate and the second clamping plate. The sealing sleeve is adapted to the two clamping grooves and is respectively clamped in the two clamping grooves. A connecting plate is fixedly installed on one side of the valve body. The connecting plate is L-shaped. A frame is fixedly installed on one side of the connecting plate. The frame is U-shaped. A spacing adjusting component is arranged inside the frame.

[0007] Preferably, the connecting component includes an internal thread formed on the inner wall of the valve body. A connecting pipe is fixedly installed on the side of the outer connecting pipe facing the valve body. An external thread is formed on the outer side of the connecting pipe. The external thread is in line with the internal thread. Both the outer connecting pipe and the connecting pipe are communicated with the valve body.

[0008] Preferably, a sealing groove is formed on one side of the valve body of the sealing assembly, and a sealing gasket is fixedly installed on one side of the outer connecting pipe facing the valve body. The sealing gasket is adapted to the sealing groove and is inserted into the sealing groove.

[0009] Preferably, the spacing adjustment assembly includes a circular hole formed on the top side of the frame. A bidirectional screw is arranged in the circular hole. The bottom end of the bidirectional screw is rotatably connected to the inner wall of the bottom side of the frame, and two sliders are slidably installed on the outer side of the bidirectional screw.

[0010] Preferably, a connecting rod is fixedly installed on one side of each of the two sliders. The two connecting rods are both L-shaped. One ends of the two connecting rods close to each other are fixedly connected to the top side of the first clamping plate and the bottom side of the second clamping plate respectively.

[0011] Preferably, a guiding groove is formed on the inner wall of one side of the frame. Two guiding blocks are slidably installed in the guiding groove. The other sides of the two guiding blocks are respectively fixedly connected to one side of the two sliders.

[0012] Preferably, a turntable is fixedly installed at the top end of the bidirectional screw. A plurality of rotating rods are fixedly installed on the outer side of the turntable. The plurality of rotating rods are distributed in a circumferential array. A threaded hole and a plurality of threaded grooves are respectively formed on the top sides of the turntable and the frame. A limiting column is threadedly installed in one threaded hole, and the other end of the limiting column is threadedly installed into the threaded groove aligned with one threaded hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. By rotating the turntable clockwise, the bidirectional screw rotates synchronously, so that the two sliders slidably installed on the outer side drive the two connecting rods to approach each other. When the two connecting rods approach each other, they will respectively drive the first clamping plate and the second clamping plate to move towards the top and bottom of the sealing sleeve, so as to squeeze the sealing sleeve. And because the first clamping plate and the second clamping plate are both provided with clamping grooves, and the sealing sleeve is fitted with the two clamping grooves, so during the squeezing process, the sealing sleeve will be clamped in the two clamping grooves, thus avoiding the situation that the sealing sleeve will deviate from the connection part. And by limiting the sealing sleeve through the first clamping plate and the second clamping plate, the third layer of sealing between the valve body and the outer connecting pipe is realized, so that the overall sealing performance is greatly improved.

[0015] 2. By aligning the external connecting pipe with the valve body and then rotating the valve body, the valve body can move towards the connecting pipe. Since the external threads provided on the outer side of the connecting pipe are in line with the internal threads provided on the inner wall of the valve body, the first - layer seal between the valve body and the external connecting pipe can be achieved. And because the sealing gasket is fixedly installed on one side of the external connecting pipe, when the external connecting pipe drives the connecting pipe to move towards the inside of the valve body, the sealing gasket will be synchronously inserted into the sealing groove provided in the valve body, thereby achieving the second - layer seal between the valve body and the external connecting pipe, and further strengthening the sealing performance between the valve body and the external connecting pipe.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figures 1-4, A valve that is easy to install, including a valve body 1. One end of the valve body 1 is provided with an outer connecting pipe 4. A connecting component and a sealing component are arranged between the outer connecting pipe 4 and the valve body 1. A sealing sleeve 8 is sleeved at the connection between the outer connecting pipe 4 and the valve body 1. A first clamping plate 16 and a second clamping plate 17 are respectively arranged above and below the sealing sleeve 8. Clamping grooves 18 are formed on the inner sides of the first clamping plate 16 and the second clamping plate 17. The sealing sleeve 8 is adapted to the two clamping grooves 18 and is clamped in the two clamping grooves 18. A connecting plate 9 is fixedly installed on one side of the valve body 1. The connecting plate 9 is L-shaped. A frame 10 is fixedly installed on one side of the connecting plate 9. The frame 10 is U-shaped. A spacing adjusting component is arranged inside the frame 10. By providing the first clamping plate 16 and the second clamping plate 17, when it is necessary to squeeze and fix the sealing sleeve 8, the first clamping plate 16 and the second clamping plate 17 can squeeze the outside of the sealing sleeve 8 through the provided spacing adjusting component. And because the first clamping plate 16 and the second clamping plate 17 are both provided with clamping grooves 18, and the sealing sleeve 8 coincides with the two clamping grooves 18, the sealing sleeve 8 will be clamped in the two clamping grooves 18 during the squeezing process, thus preventing the sealing sleeve 8 from shifting from the connection. And by limiting the sealing sleeve 8 through the first clamping plate 16 and the second clamping plate 17, the third layer of sealing between the valve body 1 and the outer connecting pipe 4 is realized, thereby greatly improving the overall sealing performance.

[0023] Specifically, the connecting component includes an internal thread 2 formed on the inner wall of the valve body 1. A connecting pipe 5 is fixedly installed on the side of the outer connecting pipe 4 facing the valve body 1. An external thread 6 is formed on the outer side of the connecting pipe 5. The external thread 6 coincides with the internal thread 2. The outer connecting pipe 4 and the connecting pipe 5 are both communicated with the valve body 1. The sealing component includes a sealing groove 3 formed on one side of the valve body 1. A sealing gasket 7 is fixedly installed on the side of the outer connecting pipe 4 facing the valve body 1. The sealing gasket 7 is adapted to the sealing groove 3 and is inserted into the sealing groove 3. By aligning the outer connecting pipe 4 with the valve body 1 and then rotating the valve body 1, it can move towards the connecting pipe 5. And because the external thread 6 formed on the outer side of the connecting pipe 5 coincides with the internal thread 2 formed on the inner wall of the valve body 1, the first layer of sealing between the valve body 1 and the outer connecting pipe 4 can be realized. And because the sealing gasket 7 is fixedly installed on one side of the outer connecting pipe 4, when the outer connecting pipe 4 drives the connecting pipe 5 to move towards the inside of the valve body 1, the sealing gasket 7 will be synchronously inserted into the sealing groove 3 formed on the valve body 1, thereby realizing the second layer of sealing between the valve body 1 and the outer connecting pipe 4, and further strengthening the sealing performance between the valve body 1 and the outer connecting pipe 4.

[0024] Specifically, the spacing adjustment component includes a circular hole opened on the top side of the frame 10. A bidirectional screw 12 is arranged in the circular hole. The bottom end of the bidirectional screw 12 is rotatably connected to the inner wall of the bottom side of the frame 10. Two sliders 13 are slidably mounted on the outer side of the bidirectional screw 12. One side of each of the two sliders 13 is fixedly equipped with a connecting rod 15. The two connecting rods 15 are both L-shaped. The ends of the two connecting rods 15 close to each other are fixedly connected to the top side of the first clamping plate 16 and the bottom side of the second clamping plate 17 respectively. When the sealing sleeve 8 is located at the connection between the valve body 1 and the outer connecting pipe 4, by clockwise rotating the turntable 19, the bidirectional screw 12 is driven to rotate synchronously, so that the two sliders 13 slidably mounted on the outer side of the bidirectional screw 12 approach each other, and then the two sliders 13 drive the two connecting rods 15 to approach each other synchronously. When the two connecting rods 15 approach each other, they will drive the first clamping plate 16 and the second clamping plate 17 to move towards the top and bottom of the sealing sleeve 8 respectively, so as to squeeze the sealing sleeve 8. And when it is necessary to replace a thicker sealing sleeve 8, only need to rotate the turntable 19 counterclockwise, then the two sliders 13 can drive the first clamping plate 16 and the second clamping plate 17 to move away from each other, and then the thicker sealing sleeve 8 can be replaced. And because the distance between the two sliders 13 is controlled by rotating the turntable 19, the sealing sleeve 8 with different thicknesses can be squeezed and fixed.

[0025] Specifically, a guiding groove 11 is opened on the inner wall of one side of the frame 10. Two guiding blocks 14 are slidably mounted in the guiding groove 11. The other sides of the two guiding blocks 14 are respectively fixedly connected to one side of the two sliders 13. By arranging the two guiding blocks 14, when the two sliders 13 approach each other, they will drive the two guiding blocks 14 to move in the guiding groove 11 opened on the frame 10, so as to guide and limit the movement of the two sliders 13.

[0026] Specifically, the top end of the bidirectional screw 12 is fixedly equipped with a turntable 19. A plurality of rotating rods 20 are fixedly mounted on the outer side of the turntable 19. The plurality of rotating rods 20 are distributed in a circular array. A threaded hole and a plurality of threaded grooves are respectively opened on the top sides of the turntable 19 and the frame 10. A limiting post 21 is threadedly mounted in one threaded hole. The other end of the limiting post 21 is threadedly mounted into the threaded groove aligned with the one threaded hole. By arranging the limiting post 21, after the fixing of the sealing sleeve 8 is completed, by threadedly mounting the limiting post 21 into the threaded hole opened on the turntable 19, and then continuing to rotate the limiting post 21, the other end of the limiting post 21 can be threadedly mounted into the threaded groove aligned with the threaded hole, so as to realize the fixed connection between the turntable 19 and the frame 10, and avoid the bidirectional screw 12 from rotating automatically due to the frame 10 being knocked, resulting in the first clamping plate 16 and the second clamping plate 17 stopping squeezing the sealing sleeve 8.

[0027] During use: By aligning the external connecting pipe 4 with the valve body 1, and then rotating the valve body 1, it can move towards the connecting pipe 5. Since the external thread 6 provided on the outer side of the connecting pipe 5 matches the internal thread 2 provided on the inner wall of the valve body 1, the first layer of sealing between the valve body 1 and the external connecting pipe 4 can be achieved. And because the sealing gasket 7 is fixedly installed on one side of the external connecting pipe 4, when the external connecting pipe 4 drives the connecting pipe 5 to move towards the inside of the valve body 1, the sealing gasket 7 will be synchronously inserted into the sealing groove 3 provided on the valve body 1, thereby achieving the second layer of sealing between the valve body 1 and the external connecting pipe 4, and further strengthening the sealing performance between the valve body 1 and the external connecting pipe 4. After the external connecting pipe 4 is installed, by moving the sealing sleeve 8 to the connection between the external connecting pipe 4 and the valve body 1, and then rotating the turntable 19 clockwise to drive the bidirectional screw 12 to rotate synchronously, the two sliders 13 slidably installed on the outer side of the bidirectional screw 12 will approach each other, and then the two sliders 13 will synchronously drive the two connecting rods 15 to approach each other. When the two connecting rods 15 approach each other, they will respectively drive the first clamping plate 16 and the second clamping plate 17 to move towards the top and bottom of the sealing sleeve 8, thereby squeezing the sealing sleeve 8. And because the first clamping plate 16 and the second clamping plate 17 are both provided with clamping grooves 18, and the sealing sleeve 8 matches the two clamping grooves 18, the sealing sleeve 8 will be clamped in the two clamping grooves 18 during the squeezing process, thus preventing the sealing sleeve 8 from shifting from the connection. After the fixing of the sealing sleeve 8 is completed, by threadedly installing the limiting post 21 into the threaded hole provided on the turntable 19, and then continuing to rotate the limiting post 21, the other end of the limiting post 21 can be threadedly installed into the threaded groove aligned with the threaded hole, thereby achieving the fixed connection between the turntable 19 and the frame 10, preventing the bidirectional screw 12 from rotating automatically due to the frame 10 being knocked, which may cause the first clamping plate 16 and the second clamping plate 17 to stop squeezing the sealing sleeve 8. By limiting the sealing sleeve 8 with the first clamping plate 16 and the second clamping plate 17, the third layer of sealing between the valve body 1 and the external connecting pipe 4 is achieved, thereby greatly improving the overall sealing performance.
