Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leakage plugging, in particular to a leak plugger for metal pipelines. Background Art

[0002] The leak plugger is a kind of leak plugging equipment used in the process of pipeline emergency repair. It is mainly used to plug the pipeline when it is damaged due to air holes, sand holes, leakage, etc. due to long-term use, so as to achieve pipeline emergency repair. It is widely used in various liquids and gases.

[0003] However, in the prior art, when repairing a leak in a metal pipe, it is necessary to place the leak plugger on the damaged part of the pipe and then connect it. Due to the different pressures inside and outside the pipe, the impact force of the fluid is relatively large, which will impact the leak plugger, making it difficult for the leak plugger to fit the outer surface of the pipe, which is troublesome for subsequent fixation. The generated fluid will splash out from the gap between the leak plugger and the pipe, wetting clothes, and even when the pressure is relatively high, it will directly impact the human body and cause injuries. In addition, some metal pipes have dirt attached to their outer surfaces, making the outer surfaces uneven. Direct leak repair will cause a gap between the leak plugger and the pipe, and the fluid will flow out, resulting in a poor sealing effect. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical solution adopted by the utility model to solve the technical problems is: a leak stopper for a metal pipe, comprising an outer cover, the outer surface of the outer cover is rotatably connected to a connecting belt, the outer surface of the connecting belt is provided with a plurality of bayonet holes, the outer surface of the outer cover is fixedly connected to a fixing block, the outer surface of the outer cover is fixedly connected to a pressure relief device, the inner surface of the outer cover is provided with an adjustment device, the inner surface of the outer cover is slidably connected to a leak-proof pad, and the outer surface of the leak-proof pad is fixedly connected to a bracket.

[0005] Preferably, the adjusting device comprises a connecting block, the outer surface of the connecting block is rotatably connected to a screw rod, the outer surface of the screw rod is threadedly connected to a rotating ring, the inner surface of the connecting block is slidably connected to an upper slider, and the inner surface of the connecting block is slidably connected to a lower slider. The outer surface of the rotating ring is rotatably connected to the outer surface of the outer cover, the outer surface of the screw rod is slidably connected to the inner surface of the outer cover, and the outer surface of the screw rod is rotatably connected to the outer surface of the connecting block. The rotating ring is rotated, and the screw rod moves downward with the connecting block through the threaded connection with the screw rod, so that the plugging pad on the fixed connection bracket of the lower slider contacts the pipeline.

[0006] Preferably, the outer surfaces of the upper slider and the lower slider are provided with sliding grooves, the inner surface of the connecting block is fixedly connected with a plurality of limit columns, and the outer surface of the lower slider is fixedly connected with the outer surface of the bracket. When the outer surface of the pipeline is uneven, as the connecting block moves downward, the lower slider at one end moves upward, so that the lower slider pushes the upper slider to slide, and during the movement of the upper slider, the lower slider at the other end is pushed downward, and the other end of the plugging pad is pressed against the outer surface of the pipeline through the bracket.

[0007] Preferably, the pressure relief device comprises a flow pipe, the inner surface of the flow pipe is fixedly connected with a filter screen, the outer surface of the filter screen is fixedly connected with a slow flow pipe, the inner surface of the flow pipe is rotatably connected with an impeller, and the outer surface of the impeller is slidably connected with the outer surface of the filter screen. The filter screen is used to limit the flow, and then the fluid is diverted along the slow flow pipe to slow down the fluid speed, and the impeller is driven to rotate during the process of the water flow passing through, scraping the surface of the filter screen to prevent dirt on the pipeline from entering the flow pipe through the fluid and blocking the filter screen.

[0008] Preferably, the inner surface of the fixed block is slidably connected with a clamping block, the outer surface of the clamping block is fixedly connected with a spring, the end of the spring away from the clamping block is fixedly connected with the inner surface of the fixed block, and the outer surface of the clamping block is slidably connected with the inner surface of the bayonet. When the connecting belt is pulled, the clamping block slides in the bayonet on the connecting belt, and the spring pushes the clamping block into the bayonet so that the connecting belt can only be tightened but not loosened.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The utility model provides a pressure relief device, and by pressing the outer cover against the pipeline, the fluid leaking from the damaged metal pipeline flows out through the circulation pipe and is limited by the filter. Then the fluid is diverted along the slow-flow pipe to slow down the fluid speed. It can also prevent the fluid from directly impacting the bending part of the circulation pipe and causing deformation. In the process of water flowing through, the impeller is driven to rotate and scrape the surface of the filter to prevent dirt on the pipeline from entering the circulation pipe through the fluid and blocking the filter. The leaked fluid is drained to avoid splashing of the fluid and wetting of clothes when the pressure inside and outside the pipeline is different during the leak repair process.

[0011] 2. The utility model is provided with an adjusting device. When the outer surface of the pipe is uneven, as the connecting block moves downward, the leak-proof pad at one end of the protrusion of the pipe first contacts the pipe, and pushes the lower slider to move upward through the bracket, so that the lower slider pushes the upper slider to slide. During the movement of the upper slider, the lower slider at the other end is pushed to move downward, and the other end of the leak-proof pad is pressed against the outer surface of the pipe through the bracket. Therefore, when the outer surface of the pipe is uneven, the damaged part of the pipe can be repaired, and the utility model is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

When the outer surface of the pipeline is uneven, as the connecting block 501 moves downward, the lower slider 505 at one end moves upward on the inner surface of the connecting block 501, so that the lower slider 505 pushes the upper slider 504 to slide, and the upper slider 504 pushes the lower slider 505 at the other end to move downward during the movement, and the other end of the plugging pad 7 is pressed against the outer surface of the pipeline through the fixedly connected bracket 6.
