Description

Technical Field

[0002] In recent years, projects such as the West-East Gas Pipeline, the utilization of offshore gas, and the import of liquefied natural gas have gradually changed the landscape of urban gas development in my country, putting it on the same development path as urban gas in other countries around the world, and laying a solid foundation for technological progress. The development, construction, and utilization of my country's gas resources will usher in a new era for urban gas development. With the increasing demand for gas in people's production and daily life, more and more gas pipelines are being laid in cities, leading to a rise in gas pipeline malfunctions. This necessitates the reconstruction, expansion, and emergency repair of existing gas pipelines, as well as the sealing and repair of damaged pipelines.

[0003] Existing pipeline sealing devices are simple in structure and have limited function. Their use requires first shutting off the main gas valve, then dismantling the gas pipeline, and finally installing the sealing device. This cumbersome process wastes time and reduces efficiency. Furthermore, partial gas leakage can occur during operation, posing a danger and causing further waste. Secondly, existing sealing devices only seal one side of the opening, resulting in an incomplete seal and the risk of gas leakage, leading to poor sealing effectiveness. Finally, after a brief sealing period, residual gas in the pipeline is released into the outside air, causing significant waste and posing a considerable hazard, thus impacting user experience.

[0004] The present invention aims to solve the technical problems existing in the prior art. To this end, a pipeline sealing device for urban gas engineering is proposed. Utility Model Content
