Abstract

The invention provides a strongly magnetic positioning airbag outer plugging device which is high in mounting speed, low in mounting resistance, highly adaptive to a leakage surface and applicable to plugging of a large-sized pipeline. According to the adopted technical scheme, the strongly magnetic positioning airbag outer plugging device comprises strongly magnetic mechanisms, a shell and an airbag, wherein the strongly magnetic mechanisms are arranged at of two ends of the shell; the airbag is embedded into the shell, extends outwards through a hole formed in the shell and is connected with a compressor guide pipe; each strongly magnetic mechanism owns an independent magnetic switch and is connected with the shell through a hinge. The strongly magnetic positioning airbag outer plugging device can be widely applied to the technical fields of leakage plugging processing of a dangerous source, safe pipeline conveying and strongly magnetic positioning.

Description

technical field [0001] The invention relates to a strong magnetic positioning airbag outer occluder, which belongs to the technical fields of dangerous source leakage sealing treatment, pipeline safety transportation, and strong magnetic positioning. Background technique [0002] With the development and expansion of chemical production scale, the operating pressure of pipeline network and equipment is constantly increasing, and leakage accidents of pipelines or equipment occur from time to time, resulting in casualties, environmental pollution and energy waste caused by leakage of chemical materials. Therefore, the sealing of pipeline and equipment leakage Work has become a very important link in the process of modern petrochemical production, storage and transportation, and there is an urgent need for fast, effective and safe plugging equipment to implement the plugging operation of the accident pipeline, so as to effectively control the source of danger and minimize its da...
