Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic-lined valve installation technology, specifically to a convenient plastic-lined valve installation tool. Background Technology
[0002] In many fields such as industrial production and municipal construction, plastic-lined valves, as key fluid control components that combine corrosion resistance, leak prevention, and good sealing performance, are widely used in the construction and maintenance of various pipeline systems. The quality of valve installation directly affects the operational stability and safety of the pipeline system. Therefore, efficient and accurate connection between valves and pipelines is an important part of pipeline construction.
[0003] In the actual installation of plastic-lined valves, the problem of distance deviation between two pipelines to be connected after the pipeline is laid out on site is often encountered. When the pipeline spacing is too large to be directly aligned with the valve flange, due to the lack of special tools to assist in connecting the pipeline and the valve, workers usually have to manually adjust the pipeline position with simple tools such as pry bars and hammers. This is not only difficult to operate and time-consuming, but also easy to cause knocking damage to the outer wall of the pipeline or the edge of the flange during the adjustment process, affecting the structural integrity of the pipeline and the flange. When manually prying the pipeline, uneven force can easily cause the pipeline to suddenly shift, which may cause collision injuries to the surrounding construction personnel, or damage the sealing surface at the pipeline interface, creating a safety hazard for later leakage, seriously affecting the safety and efficiency of the installation work. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a convenient tool for installing plastic-lined valves. It features adjustable pipe spacing, secure clamping of the pipe and valve body, convenient and labor-saving operation, and avoidance of pipe damage. This solves the problems of difficult connection, low work efficiency, easy damage, and safety hazards caused by pipe spacing deviation during the installation of plastic-lined valves.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a convenient plastic-lined valve installation tool, including a base, a first bidirectional screw, a threaded column, a rectangular tube, a rectangular rod, a fixing component, and a clamping component. The top of the base has two symmetrically arranged T-shaped grooves. The first bidirectional screw is rotatably installed inside the two T-shaped grooves. The threaded column is rotatably installed on the top of the base, near the center. The two rectangular tubes are symmetrically fixed on the top of the base. An adjustment hole is provided on one side of each rectangular tube. The rectangular rod is movably sleeved inside the rectangular tube. A bolt is threaded onto one side of the rectangular rod, passing through the adjustment hole. The fixing component is located on the top of the two rectangular rods. The two clamping components are symmetrically arranged on the top of the base, located on both sides of the rectangular tubes.
[0006] As a preferred technical solution of this utility model, the clamping assembly includes a T-shaped sliding plate, which is movably fitted inside a T-shaped groove. The first bidirectional screw passes through the T-shaped sliding plate, and a limiting hole is provided on one side of the T-shaped sliding plate.
[0007] As a preferred embodiment of this utility model, the clamping assembly further includes a mounting box, which is fixedly mounted on the top of the T-shaped slide plate. A rectangular hole is provided on one side of the mounting box, and two clamping rods are symmetrically and movably mounted inside the mounting box.
[0008] As a preferred embodiment of this utility model, the clamping assembly further includes two arc-shaped connecting rods, which are rotatably mounted on one side of the clamping rod via a round rod. The round rod passes through a rectangular hole, and a connecting block is rotatably mounted on the other end of the two arc-shaped connecting rods. A T-shaped slider is fixedly mounted on the bottom of the connecting block.
[0009] As a preferred embodiment of this utility model, the clamping assembly further includes a connecting rod, the two ends of which are respectively movably sleeved inside two limiting holes, the threaded column penetrates the connecting rod, and a T-shaped guide groove is provided at the top of the connecting rod, with the T-shaped slider movably sleeved inside the T-shaped guide groove.
[0010] As a preferred embodiment of this utility model, the fixing component includes a support plate, which is fixedly installed on the top of two rectangular rods. Two rectangular slots are formed on the top of the support plate, and a second bidirectional screw is rotatably installed on one side of the support plate, the second bidirectional screw passing through the two rectangular slots.
[0011] As a preferred embodiment of the present invention, the fixing component further includes two T-shaped plates, the bottom ends of which are movably fitted inside the rectangular groove, the second bidirectional screw passes through the T-shaped plates, and two movable holes are symmetrically opened on one side of the T-shaped plates.

First, the valve body is placed on the support plate of the fixing component, and the fixing plate provides a stable limit for the valve body. At the same time, the clamping rod of the clamping component clamps the pipeline, and the flange on the pipeline side abuts against the clamping rod, thereby completing the initial alignment of the pipeline and the valve body flange and preventing the valve body or pipeline from shifting before docking.
[0014] After initial alignment, rotating the first bidirectional screw drives the T-shaped sliding plates on both sides to move the clamped pipes toward the valve body in a synchronized manner. This allows for flexible adjustment of the distance between the two pipes, facilitating valve docking and installation. It also reduces damage to pipes and flanges caused by traditional hammering operations, making the operation convenient and labor-saving. Attached Figure Description

The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0018] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 7 The present invention will be further described below.
[0019] A convenient plastic-lined valve installation tool includes a base 1, a first bidirectional screw 3, a threaded post 4, a rectangular tube 5, a rectangular rod 7, a fixing component, and a clamping component. Two T-shaped grooves 2 are symmetrically formed on the top of the base 1. The first bidirectional screw 3 is rotatably installed inside the two T-shaped grooves 2. The threaded post 4 is rotatably installed on the top of the base 1, near the center. Two rectangular tubes 5 are symmetrically fixed on the top of the base 1. An adjustment hole 6 is formed on one side of each rectangular tube 5. The rectangular rod 7 is movably fitted inside the rectangular tube 5. A bolt is threaded onto one side of the rectangular rod 7, passing through the adjustment hole 6. The fixing component is located on the top of the two rectangular rods 7. Two clamping components are symmetrically arranged on the top of the base 1, located on both sides of the rectangular tubes 5.
[0020] In this embodiment, the base 1 serves as the fundamental support component for the entire portable plastic-lined valve installation tool, ensuring structural stability after assembly and preventing overall displacement or shaking during valve installation. T-shaped grooves 2 are symmetrically positioned on the top of the base 1, providing sliding guidance and installation space for the T-shaped slide plates 8 in the clamping assembly, restricting their movement direction, and ensuring smooth linear movement under the drive of the first bidirectional screw 3. The first bidirectional screw 3 is rotatably mounted inside the two T-shaped grooves 2 and subsequently penetrates the T-shaped slide plates 8 in the clamping assembly. Its rotation drives the two T-shaped slide plates 8 to move synchronously towards each other along the T-shaped grooves 2, thereby bringing the pipes clamped by the clamping assembly closer to the valve body on the fixed assembly, adjusting the distance between the two pipes. Connectors are fixedly mounted at both ends of the first bidirectional screw 3, allowing for the use of an electric wrench to rotate the first bidirectional screw 3. Furthermore, the T-shaped slide plates 8 can be removed from the T-shaped grooves 2 for easy transport and carrying. The threaded post 4 is rotatably mounted... Near the center of the top of the base 1, a handwheel is fixedly installed at its top for easy rotation. A connecting rod 16 from the clamping assembly can then pass through it. Rotation drives the connecting rod 16 to move axially along the threaded post 4. The rectangular tube 5 provides movable installation space for the rectangular rod 7. An adjustment hole 6 on one side engages with the bolts of the rectangular rod 7, limiting its movement trajectory and ensuring stability during height adjustment. The rectangular rod 7 is movably fitted inside the rectangular tube 5, with its top supporting the fixing assembly. A bolt threaded on one side passes through the adjustment hole 6 of the rectangular tube 5, allowing for height adjustment along the rectangular tube 5 and locking with bolts. This adjusts the height of the fixing assembly, ensuring the valve body on the fixing assembly and the pipe flange on the clamping assembly are at the same docking height, guaranteeing docking accuracy. The fixing assembly is used to place and fix the valve body, providing stable positioning for valve bodies of different sizes and preventing displacement during docking. The clamping assembly is used to clamp the pipe to be docked, simultaneously causing the pipe flange to abut against the clamping rod 12, thus moving the pipe.
[0021] Specifically, the clamping assembly includes a T-shaped slide plate 8, which is movably fitted inside the T-shaped slide groove 2. A first bidirectional screw 3 passes through the T-shaped slide plate 8, and a limiting hole 9 is provided on one side of the T-shaped slide plate 8. The clamping assembly also includes a mounting box 10, which is fixedly mounted on the top of the T-shaped slide plate 8. A rectangular hole 11 is provided on one side of the mounting box 10, and two clamping rods 12 are symmetrically and movably mounted inside the mounting box 10. The clamping assembly also includes two arc-shaped connecting rods 13, which are rotatably mounted on one side of the clamping rod 12 via a round rod. The round rod passes through the rectangular hole 11. A connecting block 14 is rotatably mounted on the other end of the two arc-shaped connecting rods 13, and a T-shaped slider 15 is fixedly mounted on the bottom of the connecting block 14. The clamping assembly also includes a connecting rod 16, with both ends of the connecting rod 16 movably sleeved inside the two limiting holes 9. A threaded post 4 passes through the connecting rod 16, and a T-shaped guide groove 17 is provided on the top of the connecting rod 16. A T-shaped slider 15 is movably sleeved inside the T-shaped guide groove 17.
[0022] In this embodiment, the T-shaped sliding plate 8 is movably fitted inside the T-shaped sliding groove 2, through which the first bidirectional screw 3 passes. It can smoothly slide along the T-shaped sliding groove 2 when the first bidirectional screw 3 rotates. The top is fixed with a mounting box 10, which can drive the mounting box 10 and the clamping rod 12 inside the box to move synchronously. A limiting hole 9 is opened on one side of the T-shaped sliding plate 8, allowing the two ends of the connecting rod 16 to be movably fitted. When the T-shaped sliding plate 8 moves, the connecting rod 16 will not affect the movement of the T-shaped sliding plate 8. The mounting box 10 provides a movable mounting cavity for the clamping rod 12. A rectangular hole 11 on one side allows a round rod to pass through, providing a channel for the round rod to move. The rectangular hole 11 also allows the round rod connecting the clamping rod 12 and the arc-shaped connecting rod 13 to pass through, providing space for the round rod to open and close with the clamping rod 12, while limiting the direction of movement of the round rod. The clamping rod 12 can... Driven by the arc-shaped connecting rod 13, the pipe can be operated in opposite directions or in opposite directions. During relative movement, the pipe can be clamped. At the same time, one side of the clamping rod 12 abuts against one side of the flange on the pipe. Subsequently, as the T-shaped sliding plate 8 moves, the pipe moves closer to the valve body. The arc-shaped connecting rod 13 can convert the axial movement of the connecting block 14 into the opening and closing action of the clamping rod 12. The bottom of the connecting block 14 is fixedly installed with a T-shaped slider 15, and the top is rotatably connected to the two arc-shaped connecting rods 13. It can move axially under the drive of the T-shaped slider 15. The T-shaped slider 15 is movably sleeved inside the T-shaped guide groove 17. When the two T-shaped sliding plates 8 move, they can slide along the T-shaped guide groove 17. When the connecting rod 16 moves axially along the threaded column 4, it can drive the T-shaped slider 15 and the connecting block 14 to move downward, and drive the arc-shaped connecting rod 13 to retract.
[0023] Specifically, the fixing component includes a support plate 18, which is fixedly installed on the top of two rectangular rods 7. Two rectangular slots are opened on the top of the support plate 18, and a second bidirectional screw 19 is rotatably installed on one side of the support plate 18, which passes through the two rectangular slots. The fixing assembly also includes two T-shaped plates 20, the bottom end of which is movably fitted inside the rectangular groove, the second bidirectional screw 19 passes through the T-shaped plate 20, and two movable holes are symmetrically opened on one side of the T-shaped plate 20. The fixing assembly also includes two push rods 21, which are movably sleeved inside the movable hole. A limit plate is fixedly installed at one end of the push rod 21, and a spring 22 is fixedly installed on one side of the limit plate. The other end of the spring 22 is fixedly installed on one side of the T-shaped plate 20. A fixing clamp 23 is rotatably installed at the other end of the push rod 21, and a rubber pad is fixedly installed on the other side of the fixing clamp 23.
[0024] In this embodiment, a support plate 18 is used to support the valve body to be installed, ensuring that the valve body remains horizontal after placement. A rectangular groove is formed on the top of the support plate 18, allowing the bottom end of the T-shaped plate 20 to be movably fitted, restricting the movement trajectory of the T-shaped plate 20 and ensuring that the T-shaped plate 20 moves linearly along the rectangular groove under the drive of the second bidirectional screw 19. The second bidirectional screw 19 is rotatably mounted on one side of the support plate 18 and passes through both rectangular grooves and the T-shaped plate 20. A handwheel is fixedly installed at one end of the second bidirectional screw 19, which can be manually rotated to drive the second bidirectional screw 19. Rotating rod 19 drives two T-shaped plates 20 to move synchronously in opposite directions along the rectangular groove, adjusting the distance between the two T-shaped plates 20 to fit valve bodies of different sizes. This ensures that the fixing clamp 23 can precisely fit the two sides of the valve body. The bottom end of the T-shaped plate 20 is movably fitted inside the rectangular groove, allowing the second bidirectional screw 19 to pass through. It can move with the second bidirectional screw 19 to adjust the distance from the valve body. Two movable holes are symmetrically opened on one side to provide movable installation space for the push rod 21, driving the push rod 21 and the fixing clamp 23 to move synchronously in opposite directions. As the push rod 21 moves closer to or further away from the valve body, one end is fixed to the limiting plate, and the other end is rotatably mounted to the fixing plate 23. This transmits the elastic force of the spring 22 to the fixing plate 23, ensuring that the fixing plate 23 always fits against the valve body. When the spring 22 is in its natural state, it applies an elastic force towards the valve body to the push rod 21, ensuring that the fixing plate 23 fits tightly against the valve body. When there are slight deviations in the valve body dimensions or when force is applied during clamping, the spring 22 can extend and retract to buffer the impact, preventing damage to the valve body from rigid clamping and enhancing the adaptability of the fixing plate 23 to the valve body. The fixed clamping plate 23 is rotatably mounted on the other end of the top rod 21, and a rubber pad is fixed on the other side. With the cooperation of the top rod 21 and the spring 22, it clamps the valve body. The angle of the fixed clamping plate 23 can be adjusted by rotation to adapt to the shape of the valve body and ensure full contact with the surface of the valve body. The rubber pad is fixedly mounted on the other side of the fixed clamping plate 23 and directly contacts the surface of the valve body, increasing the friction between the fixed clamping plate 23 and the valve body and preventing the valve body from sliding during clamping. At the same time, the rubber material is elastic and can buffer the clamping force of the fixed clamping plate 23 on the valve body.
[0025] In summary: When using this utility model, first place the base 1 on a stable surface, manually loosen the bolts on one side of the rectangular rod 7, and adjust the height of the rectangular rod 7 up and down along the rectangular tube 5. After the support plate 18 of the fixing component is in the appropriate position, manually tighten the bolts to fix the rectangular rod 7 at the corresponding position of the adjustment hole 6. Then, place the valve body on the support plate 18, manually turn the handwheel at one end of the second bidirectional screw 19 to drive the two T-shaped plates 20 to move towards each other along the rectangular groove of the support plate 18, causing the top rod 21 and the fixing clamp 23 to move closer to the valve body. The fixing clamp 23 fits against the valve body under the elastic force of the spring 22, achieving a stable limit position of the valve body. Then, place the pipe between the two clamp rods 12, manually turn the handwheel at the top of the threaded column 4 to drive the connecting rod 16 to move downward along the threaded column 4, and at the same time drive the T-shaped slider 15 and the connecting block 14 to move downward, so that the arc... The connecting rod 13 retracts and drives the clamping rod 12 to move relative to each other within the mounting box 10 via the round rod. The clamping rod 12 clamps the pipe and abuts against the pipe flange side, completing the pipe fixation. Finally, the connecting heads at both ends of the first bidirectional screw 3 can be manually or with an electric wrench to drive its rotation, causing the two T-shaped sliding plates 8 on both sides to move towards each other along the T-shaped slide groove 2. When the T-shaped sliding plates 8 move, the two ends of the connecting rod 16 move within the limiting holes 9, and the T-shaped slider 15 slides along the T-shaped guide groove 17. The T-shaped sliding plates 8 then drive the mounting box 10, clamping rod 12, and pipe closer to the valve body until the pipe flange is aligned with the valve body flange, at which point the subsequent fixing operation can be performed. Finally, the clamping assembly can be removed from the T-shaped slide groove 2 by rotating the first bidirectional screw 3, and the rectangular rod 7 and the top fixing assembly can be removed from the rectangular tube 5 by unscrewing the bolts, facilitating the transportation and carrying of the tools.
[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
