Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a pipeline repairer. Background Art

[0002] Pipelines are devices used to transport gases, liquids, or fluids containing solid particles, and are widely used in various fields. There are many types of pipelines, such as water pipes, gas pipes, and sewage pipes. They provide great convenience for industries such as shipping, municipal administration, oilfield production plants, power plants, petrochemicals, and locomotives. However, pipelines can be damaged by corrosion and aging, excessive water pressure, low temperatures, and improper construction.

[0003] In the prior art, the pipeline repairer disclosed in the invention patent "A New Pipe Repairer" with application number CN201822260669.0 (authorization announcement number CN209671869U) includes an upper semicircular chuck and a lower semicircular chuck. The lower surface of the upper semicircular chuck and the upper surface of the lower semicircular chuck are both provided with semicircular grooves matching the pipeline. Rubber sealing gaskets are provided in the semicircular grooves of the upper semicircular chuck and the lower semicircular chuck. A first connecting seat is provided on both sides of the upper semicircular chuck, and a second connecting seat is provided on both sides of the lower semicircular chuck. The first connecting seat is connected to the second connecting seat through a threaded assembly. Although this pipe repair device can quickly plug leaks without stopping water supply, its structure will cause some stagnant water or impurities to remain in the repair device area. Long-term use will inevitably pollute the water quality in the pipeline. If these impurities are to be removed, the repair device needs to be removed. When reinstalling the repair device, in order to ensure the sealing of the pipeline, it is necessary to wrap raw tape and hemp rope on the pipeline, which is very complicated.
