Description

Technical Field

[0001] The utility model relates to a pipeline leak plugging device, in particular to a pipeline leak plugging device for repairing a gas pipeline, and belongs to the technical field of gas pipeline repair. Background Art

[0002] Gas pipeline maintenance is a very important job, which involves people's life safety and comfort. In modern society, gas is widely used in homes and commercial places, providing people with important energy sources such as cooking and heating. The repair and maintenance of gas pipelines is of great significance. Gas pipeline maintenance requires a series of professional tools and equipment to ensure the accuracy and safety of the maintenance work. Gas pipelines may leak, clog, age, etc. Each problem requires a different maintenance method. For gas leakage problems, maintenance personnel usually need to use sealants, leak-proof tapes and other materials to repair the leaking points. For blockage problems, a dredge or high-pressure water gun can be used to remove blockages in the pipeline. Gas pipeline maintenance also requires compliance with safety operating procedures.

[0003] Chinese patent announcement number CN218719696U provides a gas pressure pipeline plugging device, which relates to the technical field of pipeline plugging. The utility model includes a pipeline, a first pressing block and a second pressing block, the upper surface of the second pressing block is provided with a plug-in groove, the lower surface of the first pressing block is fixedly connected with a plug-in column, the upper surface of the first pressing block is provided with a circular hole, and the inside of the circular hole is provided with a second additional slot. The utility model is provided with a second pressing block with a plugging cavity and a first pressing block with a second additional slot. When in use, the plugging cavity on the second pressing block covers the rupture of the pipeline, and then the plug-in column is aligned with the plug-in groove to fit the first pressing block and the second pressing block to the pipeline, and then the second fixing screw is used to fix it, and the leak-proof welding glue is injected through the circular hole, and the leak-proof welding glue reaches the leak-proof cavity through the first additional slot and the second additional slot to complete the plugging, which has a good protective effect and extends the service life.

[0004] However, in the above case, although the leak-sealing welding glue reaches the leak-sealing cavity through the first additional slot hole and the second additional slot hole to complete the leak-sealing, the protective effect is good and the service life is extended, but the leak-sealing glue will enter the inside of the gas pipeline, resulting in poor ventilation of the gas pipeline after the leak-sealing. At the same time, there is only one layer of repair glue, which may lead to relatively poor leak-sealing effect on the pipeline.

[0005] In view of this, the present utility model is proposed. Utility Model Content
