Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline leak repair auxiliary tools, in particular to a clamp used for leak repair by pressure welding. Background Art

[0002] Pipeline leakage during production is a common problem in fields such as chemical engineering, petroleum, and everyday production. These leaks are often the result of a combination of factors, including corrosion from the medium, environmental corrosion, and erosion. In some cases, the continuous nature of the production process and unique production conditions make it impossible to immediately stop the flow of the medium. In these circumstances, to ensure continuous and safe production, pressure plugging is a temporary solution. While this method doesn't completely resolve the problem, it is a necessary temporary measure in certain situations to prevent further losses and risks caused by the leak. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides a clamp for pressure welding and plugging leaks, which effectively solves the above technical problems.

[0004] In order to achieve the purpose of the utility model, the utility model adopts the following technical solutions: a clamp for pressure welding and plugging leaks, including a fastening block and a U-shaped clamp, the fastening block is sleeved with the U-shaped clamp; the upper end of the U-shaped clamp is fixedly connected to the upper end surface of the fastening block by two nuts; the upper end surface of the U-shaped clamp is provided with an external thread for use with the nut; the inner side of the arc of the lower end of the U-shaped clamp is provided with an anti-slip strip.

[0005] Furthermore, the inner side of the lower end of the fastening pressure block is arc-shaped and has the same diameter as the inner side of the lower end of the U-shaped clamp.

[0006] Furthermore, through holes are respectively provided at both ends of the fastening block; the U-shaped clamp passes through the through holes and is used in conjunction with the nut.

[0007] Furthermore, a groove is provided on the inner side of the arc at the lower end of the U-shaped clamp; the anti-slip strip is semicircular; a protrusion is provided at the lower end of the anti-slip strip; and the anti-slip strip is embedded in the groove through the protrusion.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This pressure-welded leak-proof fixture ensures structural stability and sealing through the sleeve design of the fastening block and the U-shaped clamp, and is suitable for rapid leak plugging under various pressure environments. Secondly, the fixed connection between the nut and the upper surface of the fastening block makes installation and disassembly more convenient, improving work efficiency. The anti-slip strip at the lower end of the U-shaped clamp increases the friction with the pipe surface, effectively preventing the fixture from slipping during use and ensuring the safety of leak plugging. Therefore, the fixture has a simple structure, is easy to operate, safe and reliable, and is suitable for emergency leak plugging needs in a variety of industrial situations.

[0014] The following is a clear and complete description of the technical solutions in the embodiments of the present invention with reference to the accompanying drawings:

[0015] like Figure 1-3 The U-shaped clamp 3 is a kind of clamp used for sealing leaks with pressure welding, comprising a fastening block 1 and a U-shaped clamp 3, wherein the fastening block 1 is sleeved with the U-shaped clamp 3; the inner side of the lower end of the fastening block 1 is arc-shaped and has the same diameter as the inner side of the lower end of the U-shaped clamp 3, so that the clamp fits the pipeline tightly to ensure timely sealing; the upper end of the U-shaped clamp 3 is fixedly connected to the upper end surface of the fastening block 1 by two nuts 2, so that the clamp is tightly connected to the pipeline; the upper end surface of the U-shaped clamp 3 is provided with an external thread that matches the nut 2 The U-shaped clamp 3 is threadedly connected to the nut 2 through the through hole 7; the inner arc side of the lower end of the U-shaped clamp 3 is provided with an anti-slip strip 4 to effectively prevent the clamp from accidentally slipping during use; the inner arc side of the lower end of the U-shaped clamp 3 is provided with a groove 6; the anti-slip strip 4 is semicircular; the lower end of the anti-slip strip 4 is provided with a protrusion 5; the anti-slip strip 4 is embedded in the groove 6 through the protrusion 5, and can be replaced at any time according to the degree of wear of the anti-slip strip 4.

[0016] During use, when a leak occurs in the pipeline, the operator can place a welding piece against the pipe wall according to the location of the leak. At this time, two clamps are used to fix the two ends of the welding piece to block the leaking part of the pipeline. The operator then tightens the nut 2 to make the anti-slip strip 4 of the U-shaped clamp 3 tightly fit with the pipeline and stop the leak. Then, the operator seals the welding piece to the pipeline through welding, completing the entire welding and leak-blocking process.

[0017] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention based on the technical solution and its improved conception, which should be covered by the protection scope of the present invention.
