【摘要】 控制往复压缩机气体进出气缸过程的气阀，作为往复压缩机系统的核心部件，其性能的高低会对压缩机的使用效率和寿命造成影响。为优化往复压缩机气阀结构，分析阀片的运动特性，分析了气阀结构中4层流道槽，在不同施压条件下的阀片等效应力及位移变化，并探讨了在不同进油压力及气阀不同弹簧刚度下的阀片运动规律，深入研究了气阀的运动特性。仿真结果表明，优化气阀结构，较大的油压以及适当的复位弹簧的刚度可以提高往复压缩机工作寿命及使用效率。更多还原

【Abstract】 As the core component of reciprocating compressor system, the air valve controls the process of reciprocating compressor gas entering and exiting the cylinder, and its performance will affect the efficiency and life of compressor.In order to optimize the valve structure of reciprocating compressor and analyze the motion characteristics of valve plate, this paper analyzed the equivalent stress and displacement changes of the valve plate under different pressure conditions in the four layers of flow channel grooves in the air valve structure, and discussed the movement law of the valve plate under different inlet pressures and different spring rates of the valve, and deeply studied the motion characteristics of air valve.The simulation results show that the optimized valve structure, large oil pressure and appropriate stiffness of the return spring can improve the working life and efficiency of reciprocating compressor.更多还原
