Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, in particular to a leak-stopping device for a gas pipeline joint. Background Art

[0002] A gas pipeline refers to a pipeline that transports gas (including associated gas produced in oil fields) from the mining site or processing plant to the urban gas distribution center or industrial enterprise users. It is also called a gas transmission pipeline. Using a gas pipeline to transport gas is a way to transport gas in large quantities on land. Gas pipelines account for about half of the total length of pipelines in the world. After a certain service life is reached during long-term use, the pipeline will often be perforated. The leaked gas causes great pollution to the environment and will also cause certain economic losses to gas transportation. Therefore, manual inspection, repair or replacement of leaks is required.

[0003] For example, a Chinese patent (publication number: CN209399032U) discloses a leak-proof device for insulating joints of gas pipelines, including a cylinder, a pressure ring and a sealing ring. The cylinder is composed of two semicircular cylinders that are matched together and surround the insulating joint. The two semicircular cylinders are connected by fasteners; both ends of the cylinder are provided with annular end face baffles extending inward, which are the first baffle and the second baffle respectively. The device can achieve online leak-proofing without affecting the normal transportation of the pipeline and the normal use of the user.

[0004] The above technical solution also has the following defects. Although the leak-plugging device for the insulating joint of the gas pipeline can realize online leak plugging and does not affect the normal transportation of the pipeline and the normal use of the user, in actual use, the installation process involves multiple steps, each step requires precise operation and inspection, and may require multiple adjustments and repeated work. Traditional fastening and positioning methods may require more physical labor and precision, which to some extent increases the complexity and time consumption of the installation process. Based on this, a leak-plugging device for a gas pipeline joint is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] It should be noted that the pipeline body 4 can be blocked by operating the anti-blocking mechanism 3, and the operator does not need to make multiple adjustments and repeat work, which saves time and effort, effectively avoids gas leakage, and further improves work efficiency.

[0026] See also Figure 1-4 304 is fixed to the inner wall of the worm wheel 303. The driving assembly further comprises two fixing seats 305 fixed to the left and right sides of the inner bottom wall of the connecting plate 1. The opposite sides of the two fixing seats 305 are rotatably connected to the left and right ends of the bidirectional screw 304 through bearings, so that the bidirectional screw 304 can rotate stably when subjected to force. The worm 301 is driven to rotate by rotating the handle 302, and the worm wheel 303 can rotate to drive the bidirectional screw 304 to rotate, thereby providing a power source for the movement of the adjusting assembly.

[0027] Among them, the adjustment component includes an adjustment slider 306 threadedly connected to the left and right sides of the outer surface of the bidirectional screw 304, and a moving hole is opened on the fixed seat 305. The moving hole and the adjustment slider 306 are slidably connected. The cross-section of the adjustment slider 306 is L-shaped, so that when the adjustment slider 306 is moved by force, it will not rotate. The adjustment component also includes a telescopic rod 307 fixed to the left and right sides of the inner cavity of the connecting plate 1. The telescopic rod 307 includes a sleeve with one end fixed to the inner wall of the connecting plate 1, and the inner wall of the sleeve is slidably connected to a moving rod with one end fixed to one end of a moving block 309. The outer surface of the telescopic rod 307 is sleeved with a spring 308, and moving blocks 309 are fixed on the opposite sides of the two telescopic rods 307. The movement of the adjusting slider 306 drives the moving block 309 to move, and then the second limiting block 314 can be driven to move.

[0028] At the same time, the anti-blocking component includes adjustment holes 310 opened on the left and right sides of the upper surface of the first blocking plate 2, the inner walls of the two adjustment holes 310 are slidably connected with connecting blocks 311, the tops of the two connecting blocks 311 are fixed with second blocking plates 312 that fit the pipeline body 4, the bottoms of the connecting blocks 311 are fixed with first limiting blocks 313, and the two first limiting blocks 313 are provided with limiting grooves 315 on the opposite sides. The anti-blocking component also includes a second limiting block 314 fixed on the top of the moving block 309, the second limiting block 314 and the limiting groove 315 are slidably connected, and the cross-sections of the connecting blocks 311 and the adjustment holes 310 are both convex A guide slider 316 is provided on the inner bottom wall of the connecting plate 1, and the inner wall of the guide slider 316 is slidably connected to two guide grooves 317, and the top of the guide groove 317 is fixed to the moving block 309. Two connecting holes are provided on the upper surface of the connecting plate 1, and the connecting holes are slidably connected to the first limiting block 313. The moving block 309 and the second limiting block 314 are moved by adjusting the movement of the slider 306, so that the second limiting block 314 is completely fitted with the inner wall of the limiting groove 315. At this time, the positions of the second blocking plate 312 and the first blocking plate 2 can be stably fixed, thereby achieving the blocking of the pipeline body 4.

[0029] It should be noted that the operator can quickly and easily seal the pipeline body 4 by operating the anti-blocking mechanism 3, which saves time and effort, effectively avoids gas leakage and improves their own work efficiency.

[0030] The working principle of the above embodiment is:

[0031] First, move the pipe body 4 between the second blocking plate 312 and the pipe body 4, at this time, the pipe body 4 is in contact with the first blocking plate 2, and then the handle 302 is turned to drive the worm 301 to rotate, so that the worm wheel 303 can rotate to drive the bidirectional screw 304 to rotate, so that the adjusting slider 306 can move along the moving hole, and then the moving block 309 can be driven to move and drive the second limiting block 314 to move. At this time, the guide slot 317 follows the movement of the moving block 309 and moves along the guide slot 317, so that the moving block 309 can move more stably and then drive the second limiting block 314 to move more stably to the appropriate position. At the same time, the telescopic rod 307 will be extended and retracted, and the spring 308 has a certain elastic force. At this time, due to the gravity of the second blocking plate 312 and the connecting block 311 themselves, they will move downward. The two blocking plates 312 will fit with the pipeline body 4, and then the handle 302 is rotated to drive the two adjusting sliders 306 to move relative to each other through the meshing force, and then the two second limiting blocks 314 are moved, so that the second limiting blocks 314 are completely fitted with the inner wall of the limiting groove 315. At this time, the positions of the second blocking plate 312 and the first blocking plate 2 can be stably fixed, and then the pipeline body 4 can be blocked, and gas leakage in the pipeline body 4 can be avoided. Operation through the pipeline body 4 does not require the operator to make multiple adjustments and repeat work, which effectively reduces the labor intensity of the staff. At the same time, compared with the traditional fastening and positioning method, it can be more convenient and stable to operate, and it is also more convenient to quickly and stably block the pipeline body 4, further improving work efficiency.
