Description

Technical Field

[0001] This utility model relates to the field of valve seat disassembly technology, specifically to an auxiliary tool for valve seat disassembly. Background Technology

[0002] Ball valves are valves that use a ball as the opening and closing element. With the rapid advancement of processing technology, testing technology, and intelligent control technology, as well as the continuous emergence of various new sealing materials, ball valve products are being used more and more widely.

[0003] In the maintenance of ball valves, it is often necessary to disassemble the pipeline ball valves. Each disassembly process involves removing the valve seat, which is a very time-consuming and labor-intensive procedure.

[0004] Because the ball valve was severely corroded, the seals behind the valve seat could not be replaced, ultimately requiring the replacement of the entire valve. Over time, valve seats often develop varying degrees of corrosion, making disassembly extremely difficult and preventing the replacement of the seals behind the valve seat. In some cases, complete valve disassembly may even be necessary. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an auxiliary tool for valve seat disassembly to solve the problems mentioned in the background art.

[0044] A horizontal plate 8 is used to connect two sliding plates 7. The horizontal plate 8 is fixedly welded to the top of the two sliding plates 7.

[0045] Threaded rod 29 is used to adjust the downward movement of the structure. Threaded rod 29 is threaded inside the horizontal plate 8.

[0046] The collar 11 is movably sleeved on the outside of the threaded rod 9;

[0047] A handle 10 is used to limit the rotation of the collar 11, and the handle 10 is fixedly welded to the outside of the collar 11;

[0048] Multiple jaws 13 are used to press and fix the valve seat parts, and the multiple jaws 13 are rotatably connected to the inner side of the collar 11;

[0049] A conical block 12 is used to compress multiple grippers 13. The conical block 12 is fixedly welded to the bottom end of the threaded rod 9.

[0050] Specifically, when the device is needed, the valve seat is placed inside the fixing plate 1, and then the threaded rods 5 on both sides are used to drive the clamping plate 4 to move inward to achieve the effect of clamping and fixing the valve seat, which can prepare for the subsequent pulling work. The sliding plate 7 is inserted into the L-shaped plate 6, and then the limiting plate is rotated to prevent the sliding plate 7 from moving out of the sliding hole. At this time, the threaded rod 9 is rotated to drive the collar 11 and the jaw 13 to extend into the valve seat. When the jaw 13 contacts the seal, the handle 10 is held to restrict the rotation and movement of the collar 11. The threaded rod 9 is rotated in the opposite direction to drive the cone block 12 to move upward and drive the jaw 13 to move outward to achieve the effect of supporting and clamping the seal. After clamping, the threaded rod 9 is rotated to drive the collar 11 and the jaw 13 to move upward, which can drive the seal to move upward, so that the seal in the valve seat can be pulled out, achieving the effect of quickly pulling out the seal.

[0051] In the embodiment: the outer wall of the conical block 12 is movably fitted with the outer side of the plurality of grippers 13, and anti-slip pads are fixedly installed on the outer side of the plurality of grippers 13.

[0052] Specifically, the conical block 12 is movably fitted together with multiple grippers 13, which can achieve the effect of squeezing the grippers 13, and can also open the grippers 13 to support the valve seat sealing assembly.

[0053] In the embodiment: anti-slip grooves are provided on the side of the two clamping plates 4 that are close to each other, and the outer sides of the two clamping plates 4 are respectively rotatably connected to the outer walls of the two threaded rods 5.

[0054] Specifically, anti-slip grooves are provided on the side of the clamping plate 4 that are close to each other, which can achieve the anti-slip effect, better clamp the valve seat, and fix the valve seat, providing fixed support force for subsequent disassembly work. The clamping plate 4 is rotatably connected to the threaded rod 5, which can drive the clamping plate 4 to move inward, thereby achieving the effect of assisting in fixing the valve seat.

[0055] In the embodiment: both L-shaped plates 6 have sliding holes inside, and the outer walls of the two sliding plates 7 are movably connected to the inner sides of the two sliding holes respectively;

[0056] Specifically, the L-shaped plate 6 has a sliding hole inside. The sliding hole does not contact the sliding plate 7, which can drive the sliding plate 7 to move laterally. This can achieve the effect of adjusting the lateral position of the horizontal plate 8, and allow multiple grippers 13 to extend into the valve seat.

[0057] In the embodiment: two limiting plates are set below the two L-shaped plates 6, and the inside of the fixing plate 1 is provided with a guide hole, which is set below the threaded rod 9;

[0058] Specifically, two limiting plates are set below the two L-shaped plates 6. When the device is in use, it prevents the sliding plate 7 from moving out of the interior of the L-shaped plates 6. The interior of the fixing plate 1 is provided with guide holes to allow displacement space for the valve seat.

[0059] Working principle: The slide plate 7 extends into the L-shaped plate 6. The threaded rod 9 is rotated, which drives the collar 11 and the jaws 13 to extend into the valve seat. When the jaws 13 contact the seal, the handle 10 is gripped to restrict the rotation of the collar 11. The threaded rod 9 is rotated in the opposite direction, which drives the cone block 12 to move upward and the jaws 13 to move outward, thereby achieving the effect of supporting and clamping the seal. After clamping, the threaded rod 9 is rotated to drive the collar 11 and the jaws 13 to move upward, thereby achieving the effect of moving the seal upward, which can pull out the seal in the valve seat, achieving the effect of quickly pulling out the seal.
