Device and method for leak plugging of heating pipe network

Abstract

A leak plugging device and method for a heating pipe network, wherein the annular body includes a first half-ring and a second half-ring, the first end of the first half-ring is pivotally connected to the first end of the second half-ring; The unit includes a push rod, and the push rod can slide in one direction along the radial direction of the ring body to the middle of the ring body; the sealing unit includes a pillar, and the front end of the pillar is provided with a sealing part that can be sealingly connected with the outer surface of the heating pipeline. The pillar can slide in one direction along the radial direction of the ring body to the middle of the ring body; when the first half-ring and the second half-ring are closed, the front end of the locking trigger part presses against the first end of the trigger lever, and the second end of the trigger lever The two ends pull the first reed and the second reed to slide circumferentially to the preset position, the front end of the pillar passes through the first through hole and the sealing part at the front end of the pillar is in sealing connection with the outer surface of the heating pipeline; the front end of the push rod Through the second through hole and against the outer surface of the heating pipeline. The invention can shorten the construction time and reduce the risk of construction personnel being scalded.

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
