Description

Technical Field

[0001] The utility model relates to the technical field of pipeline plugging, in particular to an oil and gas storage and transportation pipeline plugger. Background Art

[0002] A pipe plugger refers to a device made of reinforced natural rubber, which is inserted into a pipe and then uses the compressive deformation of the rubber ring to complete the pipe plugging. When storing and transporting oil and gas, the pipeline needs to be replaced or repaired regularly. During this process, the pipeline needs to be dismantled in sections. In order to avoid environmental pollution caused by residual oil-water mixture in the pipeline, a pipe plugger is used. However, the existing pipe pluggers for oil and gas storage and transportation still have some shortcomings. For example, most of the plugging methods are to drive the connecting structure on the inner side of the cover plate by rotating the rotating handle on the outside of the cover plate, thereby squeezing the rubber ring. This method is not only time-consuming and labor-intensive, but also because the structure of the connecting rotating handle is set at the center of the cover plate, it will also affect the sealing effect during sealing. Moreover, if the rubber ring is damaged, it cannot be disassembled and replaced in time. For this reason, we propose an oil and gas storage and transportation pipeline plugger. Utility Model Content
