Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leakage plugging, and in particular to a leakage plugging device for hazardous chemical process pipelines. Background Art

[0002] When leaks occur on hazardous chemical process pipelines due to cracks or other conditions, it is often necessary to install a sealing structure consisting of two semicircular sleeves on the outside of the pipeline. In order to facilitate the fixation of the two semicircular sleeves on the pipeline, one of the semicircular sleeves is often squeezed by thread extrusion so that the two semicircular sleeves fit tightly to the pipeline surface.

[0003] For example, the Chinese patent with publication number CN216383089U proposes a leak plugging device for hazardous chemical process pipelines, which includes a lower semicircular sleeve for sleeve on the pipeline and an upper semicircular sleeve matched with the lower semicircular sleeve, the upper semicircular sleeve is arranged in a U-shaped frame, the upper surface of the U-shaped frame is threadedly connected with a stud for pressing the upper semicircular sleeve, one end of the stud extending into the U-shaped frame is rotatably connected to the upper semicircular sleeve, a U-shaped frame for limiting the position of the stud is provided on the upper side of the stud, connecting plates are welded at both ends of the U-shaped frame, and the connecting plate is fixedly connected to the end away from the U-shaped frame A limiting block, two limiting grooves matching the limiting block are symmetrically provided on the top of the U-shaped frame, and an insertion opening is provided on the top of the limiting groove, and the connecting plate passes through the insertion opening. Compared with the prior art, the studs are limited to prevent the studs from loosening due to vibration, and the reliability of pipeline plugging is improved.
