Technical Field

[0001] The utility model belongs to the technical field of gas pipelines, and specifically relates to an emergency and rapid gas pipeline leakage blocking device. Background Art

[0002] Gas pipelines are widely used in various production links of metallurgical enterprises. Due to corrosion, stress release and other reasons, pipelines often have sand holes, cracks and other problems, causing gas leakage. The only way to deal with pipeline leakage is generally to take pressure welding as a temporary measure, followed by partial or complete suspension of production.

[0003] Patent No. 202020759994.6, published on December 8, 2020, discloses a gas pipeline leak plugging structure for rapid and safe repair of leaks. The structure includes a gas pipeline with a gas leak point and a gas leak plugging structure with a valve structure. The gas leak plugging structure is sealed to the outer wall of the gas pipeline to form a sealed chamber. The gas leak point is located within the sealed chamber. This utility model is particularly suitable for repairing leaks in gas pipelines under pressure.

[0004] In the existing technology, when a gas pipeline leaks, temporary pressure welding measures are often accompanied by the risk of fire, explosion, ignition, and poisoning; before completely shutting down production for treatment, a long preparation time is required, during which there is the possibility of accidents caused by untimely treatment.

[0011] One end of the covering belt away from the outer frame is inserted into the covering belt.

[0012] The pressure plate is provided with pressure teeth matched with the fixed shaft, and the fixed shaft is provided with gear teeth.

[0013] The technical effect of the utility model is that when there are sand holes or cracks in the gas pipeline, the pipeline is covered with the device, and the covering belt is shrunk and tightened by adjusting the stop structure, and the sealant and sealing rubber inside the covering belt are pressed against the leakage point to achieve the effect of plugging the leak.
