Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance, in particular to an inflatable pipe plug used for pipeline maintenance. Background Art

[0002] Pipeline maintenance is the main measure to maintain and restore the normal operation of transportation pipelines and their equipment. It includes regular and temporary pipeline maintenance and repairs, and the maintenance of pipeline-related communication, monitoring, power and other equipment. It is not an operation specific to pipeline maintenance. Generally speaking, pipeline maintenance refers to pipe cleaning, line maintenance and pipeline emergency repair, etc. There is an existing patent for a municipal road pipeline maintenance and plugging device, with patent publication number CN211649474U, which includes a pipeline, a plugging airbag, a top support column and a support block. After the plugging airbag is inflated, the front end is an umbrella-shaped structure, and the rear end is a column structure. The plugging airbag is provided with a first plugging through hole, a central plugging through hole and a second plugging through hole for plugging and fixing. The first plugging through hole is matched with a first plugging column, and the second plugging through hole is matched with a second plugging column. The top support column is cylindrical, and the rear end of the plugging airbag is connected to the support block. A fixed through hole is provided in the center of the support block, and an internal thread is provided in the fixed through hole. The outer periphery of the top support column matches the fixed through hole and is provided with an external thread. The support block can be threadedly fixed to the top support column, and a boss is provided on the circumference of the outer edge of the top support column toward one end of the plugging airbag. This design effectively prevents the plugging airbag from being pushed out by water pressure and strengthens the fixation of the plugging airbag.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, due to pipeline rupture during pipeline maintenance, it is necessary to seal it.

Therefore, we propose an inflatable pipe plug for pipeline maintenance to solve the above-mentioned problems. Utility Model Content
