摘　　要：针对单作用气动阀,分别提出了绝热排气法和K_(v)法,对单作用执行机构的快速动作时间进行计算。介绍了两种计算方法的计算参数和计算过程,并对气动快速动作阀门的冲击应力进行了计算。采用Profiler控制阀诊断测试系统对样阀进行检测试验,与理论计算进行对比,试验结果表明本文的理论计算方法,可为单作用气动阀门的设计、选型提供可靠保证。For single acting pneumatic valve,adiabatic exhaust method and K_(v) method are proposed respectively,and the fast action time of single acting actuator is calculated.The calculation parameters and process of the two calculation methods are introduced,and the impact stress of pneumatic quick action valve is calculated.The Profiler control valve diagnostic test system is used to test the sample valve,and the comparison with the theoretical calculation shows that the theoretical calculation method in this paper can provide a reliable guarantee for the design and selection of single-acting pneumatic valve.
