Description

Gas pipe structure convenient for quick sealing and butt joint Technical Field The utility model relates to the technical field of gas pipelines, in particular to a gas pipe structure convenient for rapid sealing and butt joint. Background In the current society, the fuel gas is used as an efficient and clean energy source and widely applied to industrial production and daily life of residents, and the fuel gas pipe is used as a key carrier for fuel gas transportation, and the performance of a connecting structure of the fuel gas pipe directly relates to the safety, stability and construction efficiency of fuel gas transportation. The traditional gas pipe connection mode is mainly flange connection, flange plates are required to be installed at two ends of the gas pipe and fastened through a plurality of bolts and nuts, but the process not only requires accurate alignment of a plurality of bolt holes on the flange plates, but also requires tightening of the nuts one by one, the operation steps are complicated, time and labor are wasted, the construction efficiency is low, the labor cost is increased, and secondly, the traditional gas pipe is filled with simple rubber rings or sealant, but the rubber rings are easily aged and deformed in the long-term use process due to the influence of factors such as gas components, temperature change and pipeline vibration, so that the sealing performance is reduced, the gas leakage phenomenon is caused, the energy waste is caused, and serious potential safety hazards exist.
