Abstract

The invention provides a leak plugging device under pressure for a heating pipeline, which includes a drain pipe, a leak plugging mechanism and a fixing mechanism; the outer wall of one end of the drain pipe is provided with an external thread for installing a valve, and the other end of the drain pipe is also provided with a plugging mechanism , the fixing mechanism is fixedly connected on the outer wall of the drain pipe, and the fixing mechanism is arranged above the leak plugging mechanism; the fixing mechanism installs the drain pipe on the heating pipeline to be plugged by a tensioner. According to the leak plugging device under pressure of the heating pipeline described in the present invention, compared with the emergency repair method of the traditional half festival, this application adopts the emergency repair method of the drain pipe and the tensioner to carry out emergency repair work on the heating pipeline, which can greatly reduce the The preparation time before emergency repair is long, and the timeliness of emergency repair is improved.

Description

technical field [0001] The invention belongs to the field of leak plugging of pipelines, in particular to a leak plugging device under pressure for heating pipelines. Background technique [0002] At present, for the emergency repair work after the heating pipeline rupture in winter in the northern region, the Huff joint in the prior art is mostly used for plugging and emergency repair. The Huff joint is composed of two castings, a set of rubber parts and bolts. The damaged part of the pipe is wrapped in the inner compartment of the half joint, and the half joint is tightened and fixed by bolts to seal the leakage. [0003] This kind of traditional Huff Festival has certain problems in actual use, especially when repairing the heating branch pipelines distributed in the city, because the underground heating pipelines in the city have small diameters and low temperature inside the pipes, the belt When pressing emergency repair operations, the traditional half festival will l...
