Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a heating pipeline repair device. Background Technology

[0002] Heating pipelines refer to the pipelines that carry the heat energy generated by heating centers such as thermal power plants from the heat source to the heating inlet of buildings. If a pipeline leaks, it is necessary to quickly seal and repair the damaged part of the pipeline. When repairing the pipeline...

[0003] For example, patent CN202020775445.8, entitled "A Quick Pipe Repair Device," discloses a device comprising a first repair sleeve and a second repair sleeve. The inner surfaces of both sleeves have a repair layer. The first sleeve has upper sealing flanges at both ends, and the second sleeve has lower sealing flanges at both ends. When the first and second sleeves are assembled, the upper and lower sealing flanges interlock. The assembled sleeves cover the leak in the pipe and are secured with straps, ensuring a tight fit between the repair layer and the leak. While this patent uses straps for securing the repair layer, the straps are prone to slippage during tightening, and the method can be unstable, reducing the effectiveness of the pipe repair. Furthermore, the need for bolts or straps for fixing makes installation inconvenient and operation difficult. Utility Model Content
