Description

Technical Field

[0001] The utility model relates to the technical field of sealing hoops for pipelines, in particular to a sealing hoops for gas pipelines. Background Art

[0002] The gas pipe is a special pipeline for transporting combustible gas. It is a metal gas pipe hose that replaces the traditional clip-on rubber hose. The gas pipe has the characteristics of easy installation, reliable connection, no gas blockage, good flexibility, long service life, and can be bent arbitrarily without deformation or gas blockage. However, the existing gas sealing structure of the gas pipeline, the pipeline connection, and the connection between the pipeline and the gas meter are generally fixed with a single-layer sealing gasket and a sealing hoop. This method may lead to poor fixation after long-term use, and it is easy to cause the pipeline to loosen or fall off, resulting in the risk of gas leakage. Therefore, the gas company's inspection personnel are required to regularly check whether the user has a gas leakage problem during use. Therefore, in order to further improve the reliability and safety of the entire pipeline use, we propose a sealing hoop for gas pipelines to solve the above problems. Utility Model Content

A plurality of spring sheets are fixedly connected to the inside of the inner hoop ring one, so that the inner hoop ring one has better elasticity when being squeezed for a long time and is not easy to lose elasticity, ensuring that when the pipeline is impacted or vibrated, the spring sheets can play a buffering role and reduce the impact force on the connection. When displacement occurs due to temperature changes or pressure fluctuations, the spring sheets can automatically adjust to maintain good sealing, which can significantly improve the reliability and safety of the entire pipeline system.
