Leaking stoppage device of pipe hole leakage points

Abstract

The invention relates to a leaking stoppage device of pipe hole leakage points. The leaking stoppage device comprises a fixing support assembly and a leaking stoppage body assembly and is characterized in that the fixing support assembly is composed of an arc support with two supporting points, a dismountable tensioning chain capable of fixing the arc support on a plugged pipe and a lead screw which is screwed in the center of the arc support and provided with an axis vertical to a center of the plugged pipe. The leaking stoppage body assembly comprises a leaking stoppage body connected with a pipe needing plugging, a pressing component which is fixedly connected with the leaking stoppage body and provided with a central hole, a sealing assembly which is fixedly pressed by the pressing component and a cover plug used for sealing the leaking stoppage body. The bottom of the sealing assembly in the leaking stoppage body assembly is flexible sealing gasket, and the upper portion is a metal compact support. The leaking stoppage device firstly plugs a leaked combustible medium, then uses fire to weld, and is specially used for leaking stoppage emergency of a steel pipe. The leaking stoppage device is an indispensable and necessary urgent repairing tool for repairing flammable and combustible pipes for oil and gas.

Description

【Technical field】 [0001] The invention relates to the sealing construction technology of petroleum, chemical industry, natural gas and other transmission pipelines, in particular to a special appliance for plugging and emergency rescue of high-pressure and high-temperature pipelines, in particular to a leakage plugging device for pipeline hole leakage. 【Background technique】 [0002] In the prior art, the non-stop leak plugging construction for the inflammable and explosive pipelines such as petroleum, chemical industry, natural gas, etc. that occurs when transporting media is usually only a manual operation. For example, using soft metal, riveting and manual extrusion of steel tiles filled with rubber sheets, and then welding the steel tiles for plugging. For example: wooden wedges, copper, aluminum, and lead sheets are manually riveted to temporarily plug leaks. When the hole is large, the wooden wedge enters a part of the pipeline, which affects the future passage of the ...

AI Technical Summary

Problems solved by technology

For example: wooden wedges, copper, aluminum, and lead sheets are manually riveted to temporarily plug leaks. When the hole is large, the wooden wedge enters a part of the pipeline, which affects the future passage of the pipeline. When the hole is small, it is difficult for the wooden wedge to fill the leak. Operation method In case of high-pressure pipelines, there is no local forced plugging tool, and the method of manual riveting with wooden wedges, copper, aluminum, and lead sheets cannot effectively block the leak point; or directly use steel tiles to press rubber sheets for manual plugging , and then weld the steel tiles on the pipeline

[0003] The above plugging method is a common basic method, but there is no special plugging tool for this method at present. Because there is only a method without special tools, there are problems such as leak plugging that cannot be welded strictly and steel tiles that can be welded, and heat conduction will damage the sealing material.
