Heat supply pipe network leaking stoppage device and method

Abstract

The invention discloses a heat supply pipe network leaking stoppage device and method. An annular body comprises a first half ring and a second half ring, and the first end of the first half ring is pivotally connected with the first end of the second half ring; a jacking unit comprises a jacking rod, and the jacking rod can slide in one way towards the middle of the annular body in the radial direction of the annular body; the sealing unit comprises a supporting column, the front end of the supporting column is provided with a sealing part capable of being in sealing connection with the outersurface of a heating pipeline, and the supporting column can slide in one way towards the middle of the annular body in the radial direction of the annular body; when the first half ring and the second half ring are closed, the front end of a locking trigger part abuts against the first end of a trigger lever, the second end of the trigger lever pulls a first reed and a second reed to slide circumferentially to the preset position, the front end of the supporting column penetrates through a first through hole, and the sealing part at the front end of the supporting column is in sealing connection with the outer surface of the heat supply pipeline; and the front end of the jacking rod penetrates through a second through hole to abut against the outer surface of the heat supply pipeline. According to the heat supply pipe network leaking stoppage device and method, the construction time can be shortened, and the risk that the construction personnel can be scalded is reduced.

Description

technical field [0001] The invention relates to the technical field of leak plugging equipment for a heating pipe network, in particular to a leak plugging device and method for a heating pipe network. Background technique [0002] In the heating pipe network, after a long period of use, metal pipes are corroded by circulating water, and puncture holes often appear on the pipes, resulting in leakage. If the hot water circulation is turned off for maintenance, on the one hand, it will cause a heating stop and affect the normal life of users; on the other hand, it is often necessary to pump out all the hot water in the pipe network before construction, wasting a lot of water resources. [0003] The rapid plugging technology under pressure refers to the plugging operation performed without shutting down and reducing the operating pressure and temperature after the medium leakage in the production system is found. In the prior art, there are roughly three types of under pressur...

Problems solved by technology

[0006] However, the construction time of the above plugging devices or technologies is relatively long, and the circulating water in the heating pipe network has a relatively high temperature. The longer the construction time of the operator, the greater the risk of being scalded
