Description

Technical Field

[0001] The utility model belongs to the technical field of gas pipelines, and in particular relates to a gas pipeline anti-leakage structure. Background Art

[0002] Gas pipeline refers to a special pipeline system used to transport gas media such as natural gas and liquefied petroleum gas, and is an important part of the urban gas supply infrastructure. The gas transported in the gas pipeline is dangerous, so the gas pipeline needs to ensure that there is no leakage of gas during transportation to avoid safety hazards. However, most common gas pipelines only install simple sealing rings on the docking contact surface when docking, and then use sealants to seal after the docking is completed. This structure has a certain sealing effect in the initial stage and can ensure that the gas will not leak. However, as the use time increases, the pipeline will be offset due to external forces during use, causing gaps in the joint due to shaking, so that the sealant cannot maintain the sealing effect, and the sealing ring may fall off, causing gas leakage, posing certain safety hazards.

[0003] Secondly, as a kind of energy source, gas leakage will cause energy waste, which is not in line with the current concept of sustainable development. Moreover, gas leakage may cause physical discomfort to people around.

[0004] In summary, there are some problems in the use of gas pipelines without anti-leakage structures, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
