Description

Technical Field

[0001] The utility model relates to the technical field of pipeline compensators, in particular to a pipeline compensator which is easy to assemble and disassemble. Background Art

[0002] A pipe compensator is a device installed in a piping system. When transporting media, pipes can deform and move due to temperature fluctuations in the medium, thermal expansion and contraction of the pipe itself, external forces, ground settlement, and other factors. If left untreated, the pipes can become damaged or even rupture, leading to safety incidents such as leaks. Pipe compensators absorb these displacements and deformations. For example, the common bellows compensator acts like a flexible "joint." As the pipe lengthens or shortens, the bellows of the compensator expands or compresses accordingly, effectively protecting the safe operation of the pipeline system and extending its service life.

[0003] Existing pipe compensators still have some shortcomings in practical applications. First of all, when installing existing pipe compensators on the market, flanges need to be fixedly installed on both ends of the compensator, and then fixedly connected to the pipeline through the flanges. The connection between the two sets of flanges is currently mostly fixed with screws and nuts. This connection method is time-consuming and labor-intensive, and disassembly and assembly are cumbersome, which affects installation efficiency. Utility Model Content

The pipe compensator which is easy to disassemble and assemble is convenient for quick disassembly and assembly by setting a hollow cylinder, a sliding rod, a threaded groove, a fixed disk, a round rod, a clamping rod, a torsion spring, a spring, and a short rod. The spring pushes the sliding rod to slide outward on the inner wall of the hollow cylinder and causes the short rod to expand outward and be clamped on the outer wall of the pipe. The fixed disk is rotated to limit the position of the hollow cylinder, thereby realizing quick installation of the compensator and avoiding the cumbersome disadvantages of traditional screw and nut connections.

[0013] 2. This easy-to-disassemble pipe compensator is equipped with a bevel block, a connecting rod, a sealing strip, a top spring, and an extrusion rod to seal the pipe interface. The extrusion rod squeezes the bevel block so that the bevel block slides on the inner wall of the pipe and pushes the sealing strip at the end of the connecting rod close to each other to seal the interface and prevent gas leakage.

[0019] like Figures 1-4 As shown, the utility model provides a technical solution: a pipeline compensator that is easy to disassemble and assemble, including a compensator 1, a pipeline 2 is provided on the outer wall of the compensator 1, a quick mechanism 3 is provided on the outer wall of the compensator 1, and a sealing mechanism 4 is provided on the inner wall of the pipeline 2.

[0020] The above-mentioned quick mechanism 3 includes: a hollow cylinder 301, a slide rod 302, a threaded groove 303, a fixed plate 304, a round rod 305, a clamping rod 306, a torsion spring 307, a spring 308, and a short rod 309. The hollow cylinder 301 is slidably mounted on the inner wall of the compensator 1, the slide rod 302 is slidably mounted on the inner wall of the hollow cylinder 301, the outer wall of the hollow cylinder 301 is provided with a threaded groove 303, the outer wall of the hollow cylinder 301 is rotatably mounted with a fixed plate 304, the fixed plate 304 is threadedly connected to the threaded groove 303, the slide rod 30 2 is fixedly mounted with a round rod 305 on the outer wall, a clamping rod 306 is rotatably mounted on the outer wall of the round rod 305, a torsion spring 307 is sleeved on the outer wall of the round rod 305, one end of the torsion spring 307 is fixedly mounted on the outer wall of the round rod 305, and the other end of the torsion spring 307 is fixedly mounted on the outer wall of the clamping rod 306, a spring 308 is fixedly mounted on the inner wall of the hollow cylinder 301, one end of the spring 308 is fixedly mounted on the inner wall of the hollow cylinder 301, and the other end of the spring 308 is fixedly mounted on the inner wall of the slide rod 302, the slide rod 302 The inner wall is hinged with a short rod 309, and the inner wall of the pipe 2 is provided with a circular opening. By pulling the card rod 306, the card rod 306 is reversed and the limit on the slide rod 302 is released. At this time, the hollow cylinder 301 is aligned with the circular opening on the pipe 2. At this time, the compensator 1 is pushed to insert the hollow cylinder 301 into the circular opening on the inner wall of the pipe 2. At this time, the short rod 309 is squeezed by the circular opening to push the slide rod 302 to slide inward on the inner wall of the hollow cylinder 301 and fold the short rod 309 inward. At this time, the compensator 1 is continued to be pushed. When it is pushed to a certain distance, the circular opening is aligned with the inner wall of the hollow cylinder 301. When the short rod 309 is squeezed, the spring 308 will push the slide bar 302 to slide outward on the inner wall of the hollow cylinder 301 and make the short rod 309 expand outward and get stuck on the outer wall of the pipe 2. At this time, the fixed disk 304 is rotated to limit the hollow cylinder 301. At the same time, the clamping rod 306 is loosened, and the torsion spring 307 will make the clamping rod 306 reverse and get stuck into the inner wall of the hollow cylinder 301 and limit the slide bar 302, preventing the staff from accidentally touching the slide bar 302 and causing the short rod 309 to release the limit on the pipe 2.

[0021] The above-mentioned sealing mechanism 4 includes: a ramp block 401, a connecting rod 402, a sealing strip 403, a top spring 404, and an extrusion rod 405. The ramp block 401 is slidably installed on the inner wall of the pipe 2, and the inner wall of the ramp block 401 is fixedly installed with a connecting rod 402. The connecting rod 402 slides on the inner wall of the pipe 2, and the end of the connecting rod 402 is fixedly installed with a sealing strip 403. The outer wall of the connecting rod 402 is sleeved with a top spring 404, one end of the top spring 404 is fixedly installed on the inner wall of the ramp block 401, and the other end of the top spring 404 is fixedly installed on the inner wall of the pipe 2. The outer wall of the compensator 1 is fixedly installed with an extrusion rod 405. When pushing the compensator 1, the extrusion rod 405 will squeeze the ramp block 401 so that the ramp block 401 slides on the inner wall of the pipe 2 and moves the sealing strip 403 at the end of the connecting rod 402 close to each other and seal the interface to prevent gas leakage.

[0022] Working principle: Pull the card rod 306 to reverse the card rod 306 and release the limit on the slide rod 302. At this time, align the hollow cylinder 301 with the circular opening on the pipe 2. At this time, push the compensator 1 to insert the hollow cylinder 301 into the circular opening on the inner wall of the pipe 2. At this time, the short rod 309 is squeezed by the circular opening and pushes the slide rod 302 to slide inward on the inner wall of the hollow cylinder 301, causing the short rod 309 to fold inward. At this time, continue to push the compensator 1. When it is pushed to a certain distance, the circular opening squeezes the short rod 309. At this time, the spring 308 will push the slide bar 302 to slide outward on the inner wall of the hollow cylinder 301 and make the short rod 309 expand outward and clamp on the outer wall of the pipe 2. At this time, the fixed disk 304 is rotated to limit the hollow cylinder 301. At the same time, the clamping rod 306 is loosened, and the torsion spring 307 will make the clamping rod 306 reverse and clamp into the inner wall of the hollow cylinder 301 and limit the slide bar 302, preventing the staff from accidentally touching the slide bar 302 and causing the short rod 309 to release the limit on the pipe 2. At the same time, the extrusion rod 405 will squeeze the inclined surface block 401 so that the inclined surface block 401 slides on the inner wall of the pipe 2 and moves the sealing strip 403 at the end of the connecting rod 402 close to each other and seals the interface to prevent gas leakage. When disassembling, the fixing plate 304 is rotated to release the limit of the hollow cylinder 301. At this time, the clamping rod 306 is pulled to make the end of the clamping rod 306 withdraw from the inner wall of the hollow cylinder 301 to release the limit of the sliding rod 302. At this time, the sliding rod 302 is pushed to make the sliding rod 30 As the inner wall of the hollow cylinder 301 slides inward, the short rod 309 folds inward as pushed by the sliding rod 302. The hollow cylinder 301 is then pulled out of the circular opening on the inner wall of the pipe 2 and the limit is released. The compensator 1 can then be pulled out. As the compensator 1 is pulled out, the squeezing rod 405 releases the squeezing of the inclined surface block 401. The top spring 404 pushes the inclined surface block 401, causing it to pull the sealing strip 403 at the end of the connecting rod 402 away from each other and release the seal.

[0023] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
