Abstract


The air valve is the core component of the cyclic operation of the compressor cylinder, and its structure and performance largely determine whether the reciprocating compressor can operate more efficiently and economically. On the basis of analyzing the basic structure and working principle of the air valve, this article mainly studies the motion characteristics of the suction valve plate. Based on fluid structure coupling mechanics and using ADINA software as a platform, numerical simulation analysis was conducted on the suction valve of a certain compressor model. Studying the stress of the valve plate and the variation of its upper and lower surface pressure with the opening and closing of the valve plate during the suction process of the compressor provides theoretical guidance for the rationality of the design of the air valve and related components, thereby improving the service life of the air valve and the working efficiency of the compressor.
