Embodiment Construction

[0041] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0042] figure 1 It is a longitudinal sectional view of a sealing device for pipeline leakage provided by an embodiment of the present disclosure, as shown in figure 1 As shown, the blocking device includes a sealing sleeve compression assembly 1 and a pressure-bearing cover body 2 .

[0043] The sealing sleeve compression assembly 1 includes a sealing sleeve 11 and a compression barrel 12. The sealing sleeve 11 is used to seal and fit the outer wall of the pipeline 200. The compression barrel 12 includes an open end 121 and a sealing end 122. The open end 121 is sealed and crimped on the On the sealing sleeve 11, a through hole 1221 communicating with the opening end 121 is arranged on the sealing end 122, and a quick connector 12...

Abstract

The invention provides a plugging device and method for pipeline leakage, and belongs to the field of pipeline plugging. The plugging device comprises a sealing sleeve pressing assembly and a pressure-bearing cover body, the sealing sleeve pressing assembly comprises a sealing sleeve and a pressing barrel, the pressing barrel comprises an opening end and a sealing end, the opening end is connected to the sealing sleeve in a sealed and pressed mode, a through hole communicating with the opening end is formed in the sealing end, a quick connector is inserted into the through hole, the pressing barrel is bound to a pipeline through a first rope, and a first protruding block is arranged on the peripheral wall of the pressing barrel; and the pressure-bearing cover body comprises a barrel body and a cover cap, the barrel body comprises a first cylinder, a second cylinder and a flange ring, the end, back to the flange ring, of the second cylinder is used for being welded to the outer wall of the pipeline, and the cover cap is detachably installed at the end, back to the flange ring, of the first cylinder in a sealed mode. By means of the plugging device, and the plugging efficiency of the damaged pipeline can be improved.

Description

technical field [0001] The disclosure belongs to the field of pipeline sealing, and in particular relates to a sealing device and a sealing method for pipeline leakage. Background technique [0002] Oil and gas pipelines are the main production facilities for oil and gas development, production and export. Due to factors such as medium corrosion and improper construction operations, accidents caused by damage to oil and gas pipelines are increasing year by year. [0003] In order to avoid accidents, it is necessary to block the oil and gas pipeline in time after the oil and gas pipeline is damaged. In the related technology, the two ends of the damaged oil and gas pipeline are usually blocked by a plugging device, and then the medium in the damaged oil and gas pipeline is emptied, and then the pipe is broken, and finally a new oil and gas pipeline is replaced by welding , and remove the blockage of the blocking device, and restore the normal transportation of the pipeline....
