Self-adaptive inclination-adjustable gas backflow prevention pipeline structure

Abstract

The invention discloses a self-adaptive inclination-adjustable gas backflow prevention pipeline structure. The self-adaptive inclination-adjustable gas backflow prevention pipeline structure comprisesa pipe body, an air bag and a flange plate, a blocking piece is arranged on the inner wall of the middle of the pipe body in a bonded mode, a mounting ring and the air bag are fixedly arranged on theinner wall of the side end of the pipe body, a telescopic groove is formed in the inner side of the mounting ring, a telescopic piece is connected into the telescopic groove through a spring, the flange plate is installed at the edge end of the pipe body, a fixing plate is fixedly arranged on the bottom of the pipe body through bolts, a supporting column is connected to the bottom of the fixing plate through a shaft, an adjusting rod is connected to the outer side of the supporting column through a universal ball connecting piece, one end of the adjusting rod is located in an adjusting groove, and the adjusting groove is formed in the bottom of the supporting rod. The self-adaptive inclination-adjustable gas backflow prevention pipeline structure can be automatically suitable for being inbutt joint with different gas outlet pipes, meanwhile, gas backflow is effectively prevented, and the inclination angle of the pipe body can be adjusted according to the on-site installation position.

Description

technical field [0001] The invention relates to the technical field of gas equipment, in particular to an adaptive anti-gas backflow pipeline structure with adjustable inclination. Background technique [0002] Gas is a combustible gas, which is divided into liquefied petroleum gas, natural gas and coal gas. Transmission provides channels, but the existing pipeline structure has the following problems in use: [0003] The pipe structure is aimed at the use of gas, including the pipe body and the support installation part. It is necessary to connect the pipe body and the outlet pipe. In order to improve the scope of use of the pipe body, it is necessary to carry out adaptive docking installation with different outlet pipes. At the same time, for different installation environments, the pipeline structure needs to be able to adjust its inclination angle. [0004] In view of the above problems, it is urgent to carry out innovative design on the basis of the original pipeline ...
