AI Technical Summary
Existing pipeline sealing airbags are prone to displacement or deformation under high pressure, resulting in poor sealing. This is especially true in irregular or severely corroded pipelines, where the sealing effect is poor, affecting reliability and safety.
A high-pressure sealing rubber airbag for pipelines was designed, which uses components such as a fixed plate, slider, threaded sleeve and support. The airbag is fastened to the inner wall of the pipeline through threaded transmission and linkage structure, and the stability is enhanced by flexible alloy plate and piston plate.
It improves the stability and sealing performance of the airbag in complex pipeline environments, reduces the risk of plugging failure, and is suitable for pipeline plugging operations under various working conditions.
