Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leakage blocking, in particular to a pipeline perforation leakage blocking device. Background Art

[0002] After an oil pipeline has been in use for a long time, the pipe wall will be affected by various complex factors, which will cause pipeline perforation and oil leakage. The leaked oil will cause certain pollution to the surrounding soil and cause a certain waste of resources. At the same time, it will also require a lot of manpower and material resources to repair the pipeline.

[0003] The patent document with announcement number: CN220303106U discloses "a pressure-sealed leak-plugging device for oil pipelines". The positioning mechanism is fixed to the oil pipeline through a locking mechanism. The staff adjusts the leak-plugging mechanism according to the position of the perforation in the oil pipeline, and uses the leak-plugging mechanism to plug the position of the perforation in the oil pipeline, which is convenient for the staff to operate and no longer needs to adjust the entire device according to the position of the perforation.

[0004] However, when the above-mentioned device is used to seal the pipeline, because the pipeline is in a pressurized state, after the sealing mechanism is clamped on the outside of the pipeline, the oil inside the pipeline will splash out due to the pressure, which not only affects the sealing operation but also causes waste of oil. Therefore, it is necessary to provide a pipeline perforation and plugging device to solve the above-mentioned technical problems. Utility Model Content
