带安全阀功能的减压阀动态特性仿真与分析

摘要

This paper introduces the internal structure and working principle of a new type of pressure regulator with relief valve’s function which is compact and can be installed in pipe .And simulation model in AMESim is built for performance analysis .Research results show that spring stiffness ,diameter of the inlet hole ,spring compression at zero displacement and feedback area have great influence on the dynamic characteristic of the regulator ,and all will be useful for understanding and designing the pressure regulator with relief valve’s function .%阐述了一款结构紧凑的管式带安全阀功能的减压阀内部结构和工作原理，并基于AMESim软件建立了直观的仿真模型进行仿真验证和性能分析。研究表明：带安全阀功能的减压阀的弹簧刚度、进油孔直径、弹簧预紧力和反馈作用面直径等对其的动态响应起着重要作用。这一结果对理解和合理设计带安全阀功能的减压阀具有一定的参考意义。
