介绍了FAD160/40型安全阀的结构和工作原理,利用AMESim的元件设计库建立了安全阀的模型,并进行仿真,得到了安全阀工作时的特性曲线。通过分析仿真结果可知合理选取阀口搭合量和弹簧刚度可优化安全阀的动态特性。
The structure and working principle of safety valve FAD160 / 40 are introduced. The safety valve model is established by using AMESim ’s component design library, and the characteristic curve of safety valve is obtained. By analyzing the simulation results, we can know the dynamic characteristics of the safety valve can be optimized by properly choosing the amount of valve port and the spring rate.
