直动式纯水溢流阀设计与仿真分析

Design and Simulation of Direct-acting Water Hydraulc Relief Valve

通过给定的性能要求和试验要求,对纯水溢流阀进行了结构设计,几何尺寸计算和动态特性研究,在AMESim环境下建立了仿真模型,并用实验台输出曲线验证了该模型的正确性,通过FLUENT软件对直动式纯水溢流阀内部流场进行了仿真,进一步肯定了该结构参数的可行性,其结构参数对后续研究工作具有一定的参考意义。

In the paper,depending on the property and experimental requirements,it designs the struction,size-setting and the research of dynamic characteristics of water hydraulic relief valve.A simulation model established in the AMESim environment is compared with the testbed model to verify that it is correct.the internal flow of a direct-acting pure water relief valve is carried out by applying fluent.And the feasibility of the method is further confirmed through a series of simulation of this model.
