Problems solved by technology

[0003] However, as far as the existing municipal pipelines are concerned, when the pipeline needs to be blocked, it is usually necessary to close the valve to stop the liquid supply, and then disassemble the pipeline and add a plug. The whole process requires a lot of time and manual labor. It is also inconvenient, and the impurities carried by the liquid in the pipeline can easily block the pipeline. Since the pipeline is usually a closed structure, it is difficult to clean

Abstract

The invention provides a municipal pipeline provided with a plugging device and based on liquid nitrogen conveying, and relates to the field of pipeline plugging, the municipal pipeline comprises a left connecting pipe, the right end of the left connecting pipe is connected with a right connecting pipe, the outer side wall of the joint of the left connecting pipe and the right connecting pipe is slidably connected with a threaded fixing sleeve, a filter cartridge is welded in the left connecting pipe, and a backwashing cylinder is slidably connected in the filter cartridge; a connecting arm is connected to the right side wall of the backwashing cylinder, a control rod is rotationally connected to the middle of the interior of a right connecting pipe, a rotating rod drives the control rod to rotate through an L-shaped connecting rod, and the control rod drives a control seat to move leftwards through a first thread; a parallelogram structure composed of the pull rod, the side wall supporting plate and the supporting sleeve rod is driven by the main pull arm to become a rectangular structure, so that the left end of the side wall supporting plate drives the plugging face to be unfolded, the pipeline plugging operation is achieved, the plugging operation is better completed, the operation complexity is reduced, and the operation efficiency is improved. The problems that the pipeline is difficult to block and impurities are difficult to remove and filter are solved.

Description

technical field [0001] The invention relates to the technical field of pipeline plugging, in particular to a municipal pipeline equipped with a plugging device based on liquid nitrogen transportation. Background technique [0002] Municipal pipelines are an important part of urban infrastructure construction and the key to ensuring the normal operation of urban water supply and drainage systems. Pipes used for special purposes can also transport liquid nitrogen while taking into account water supply and drainage, thereby improving the diversity of pipeline use. . [0003] However, as far as the existing municipal pipelines are concerned, when the pipeline needs to be blocked, it is usually necessary to close the valve to stop the liquid supply, and then disassemble the pipeline and add plugs. The whole process requires a lot of time and manual labor. It is also inconvenient, and the impurities carried by the liquid in the pipeline are also very easy to block the pipeline. S...
