Abstract
Description
Technical Field
[0001] This utility model relates to the field of split joint technology, and more specifically, to a split joint with good sealing effect. Background Technology
[0002] A pipe sealer is a type of pipe leak repair device. Both pipe sealers and socket-type pipe sealers are emergency repair devices. A socket-type pipe sealer is used to repair leaks at the socket joint of two pipes, while a pipe sealer is used to repair leaks at the joint other than the socket.
[0003] The existing split joint consists of two split joint halves connected together by multiple bolts. Each half of the split joint is equipped with a sealing gasket to seal the pipeline and prevent leaks. However, because there is a cavity between the split joint halves and the pipeline, liquid inside the pipeline can flow into the cavity formed between the split joint and the pipeline through the leak. This makes it difficult to directly seal the leak in the pipeline, and its sealing effect on the pipeline is poor. Utility Model Content

[0008] The present invention is further provided that the rotating shaft is provided with a first annular groove, and a sealing ring is sleeved inside the first annular groove to ensure the sealing effect of the rotation between the rotating shaft and the round tube.
[0009] The present invention is further configured such that a fixing block is fixedly connected to the half of the split section at the position corresponding to the round tube, a sliding groove is provided on the fixing block, a sliding plate is slidably arranged inside the sliding groove, a positioning plate is fixedly connected to the side end of the sliding plate, a second annular groove is provided on the outside of the rotating shaft, and the positioning plate is inserted into the inside of the second annular groove to limit the rotation of the shaft.
[0010] The present invention is further configured such that a fixing screw that mates with the slide plate is threaded onto the fixing block, which facilitates fixing the slide plate.
[0011] The present invention is further provided that a handle is fixedly connected to the side end of the rotating shaft to facilitate the rotation of the rotating shaft.
[0012] The present invention is further configured such that each of the half-sections is provided with a groove, and a sealing strip is fixedly connected to the side end of the first sealing gasket.

[0014] The present invention is further configured such that the liquid collecting bottle is a transparent bottle, which facilitates observation of the inside of the liquid collecting bottle.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a half-joint with good sealing effect, which has the following beneficial effects:
[0017] 1. Two half-sections are fitted onto the outside of the leaking part of the pipeline, and the bolts are tightened to clamp the two half-sections onto the outside of the pipeline. The first sealing gasket provides a seal at the connection. By rotating the shaft and the screw, the screw rotates and moves the threaded pipe relative to the screw. The threaded pipe drives the compression seat and the second sealing gasket to move, pressing the second sealing gasket against the outside of the pipeline and sealing the leaking part. This facilitates direct sealing of the leaking part of the pipeline and provides a double-layer seal for the pipeline, which improves the sealing effect compared to existing technologies.
[0018] 2. The sliding plate slides inside the groove, and the sliding plate allows the positioning plate to be inserted into the second annular groove. Then, the fixing screws are tightened to fix the sliding plate and the positioning plate. The positioning plate is inserted into the second annular groove, which can ensure the normal rotation of the shaft and prevent the shaft from moving along the axial direction. This prevents the pressure of the liquid being transported inside the pipeline from pushing the second sealing gasket, the compression seat, the threaded pipe, the screw and the shaft to move, thus ensuring the sealing effect at the pipeline leak.
[0019] 3. By setting up drain pipes, valves, and collection bottles, open the valves and observe whether liquid flows out of the split joint to determine whether the second sealing gasket is damaged. If liquid flows out, collect the discharged liquid through the collection bottle. Prevent the liquid with a certain pressure inside the pipe from spraying out when the valve is opened, and prevent the liquid from spraying onto the staff. Attached Figure Description

[0029] Please see Figures 1-5 A type of split joint with good sealing effect includes two split joint halves 1, which are connected by multiple bolts 2. Each of the two split joint halves 1 is provided with a first sealing gasket 3 and a groove 20. A sealing strip 21 is fixedly connected to the side end of the first sealing gasket 3, and the sealing strip 21 is clamped inside the groove 20 to prevent the first sealing gasket 3 from falling off the split joint halves 1. A round tube 4 is fixedly connected to the split joint halves 1. A rotating shaft 5 is rotatably connected inside the round tube 4, and a first annular groove 11 is provided on the rotating shaft 5. A sealing ring 12 is fitted inside the groove 11 to ensure the sealing effect of the rotation between the rotating shaft 5 and the round tube 4. A handle 19 is fixedly connected to the side end of the rotating shaft 5 to facilitate the rotation of the rotating shaft 5. A screw 6 is fixedly connected to one end of the rotating shaft 5 that extends into the interior of the half-body 1. A threaded tube 7 is threadedly connected to the outside of the screw 6. A pressing seat 8 is fixedly connected to the side end of the threaded tube 7. A second sealing gasket 9 is fixedly connected to the side end of the pressing seat 8. Multiple telescopic rods 10 are fixedly connected to the side end of the pressing seat 8. The other end of the multiple telescopic rods 10 is fixedly connected to the inner wall of the half-body 1.
[0030] Specifically, two half-sections 1 are fitted onto the outside of the leaking part of the pipeline, and bolts 2 are tightened to clamp the two half-sections 1 onto the outside of the pipeline. The first sealing gasket 3 provides a seal for the connection. By rotating the shaft 5 and the screw 6, the screw 6 rotates and moves the threaded pipe 7 relative to the screw 6. The threaded pipe 7 drives the compression seat 8 and the second sealing gasket 9 to move, so that the second sealing gasket 9 is pressed against the outside of the pipeline and seals the leaking part. This facilitates direct sealing of the leaking part of the pipeline and provides a double seal for the pipeline, which improves the sealing effect compared to the existing technology.
[0031] Please see Figure 1 , Figure 4 and Figure 5 A fixing block 13 is fixedly connected to the half body 1 at the position corresponding to the round tube 4. A sliding groove 14 is provided on the fixing block 13. A sliding plate 15 is slidably arranged inside the sliding groove 14. A positioning plate 16 is fixedly connected to the side end of the sliding plate 15. A second annular groove 17 is provided on the outside of the rotating shaft 5. The positioning plate 16 is inserted into the inside of the second annular groove 17. A fixing screw 18 that mates with the sliding plate 15 is threaded on the fixing block 13 to facilitate fixing the sliding plate 15.
[0032] Specifically, the sliding plate 15 slides inside the groove 14, and the sliding plate 15 is used to insert the positioning plate into the second annular groove 17. Then, the fixing screw 18 is tightened to fix the sliding plate 15 and the positioning plate 16. The positioning plate 16 is inserted into the second annular groove 17, which can ensure the normal rotation of the rotating shaft 5 and prevent the rotating shaft 5 from moving along the axial direction. This prevents the pressure of the liquid transported inside the pipeline from pushing the second sealing gasket 9, the compression seat 8, the threaded pipe 7, the screw 6 and the rotating shaft 5 to move, thus ensuring the sealing effect at the pipeline leak.
[0033] Please see Figure 1 A drain pipe 22 is connected to the half-body 1. A valve 23 is installed on the drain pipe 22. A collection bottle 24 is threaded onto the drain pipe 22. The collection bottle 24 is a transparent bottle, which makes it easy to observe the inside of the collection bottle 24.
[0034] Specifically, by setting up a drain pipe 22, a valve 23, and a collection bottle 24, the valve 23 is opened, and it is observed whether liquid flows out of the half joint to determine whether the second sealing gasket 9 is damaged. If liquid flows out, the discharged liquid is collected through the collection bottle 24. At the moment the valve 23 is opened, liquid with a certain pressure inside the pipe is prevented from spraying out, so as to prevent liquid from spraying onto the staff.
[0035] In summary, when using the overall equipment:
[0036] Two half-sections 1 are fitted onto the outside of the leak in the pipe, and the compression seat 8 and the second sealing gasket 9 are aligned with the position of the leak on the pipe. Then, the bolts 2 are tightened to clamp the two half-sections 1 onto the outside of the pipe. The first sealing gasket 3 provides a seal for the connection. By rotating the shaft 5 and the screw 6, the screw 6 rotates and moves the threaded pipe 7 relative to the screw 6. The threaded pipe 7 drives the compression seat 8 and the second sealing gasket 9 to move, so that the second sealing gasket 9 is pressed against the outside of the pipe and directly seals the leak.
