控制阀阀芯型线方程对阀前后压差有着重要的影响.基于有限元分析软件ANSYS,建立了控制阀的仿真模型,并对不同阀芯型线的模型进行了仿真分析,得出了不同阀芯型线对阀前后压降的影响.同时,在考虑流固耦合作用下对控制阀阀体进行了应力分析.通过耦合场分析,可以避免应力集中,提高阀体的使用寿命,优化设计阀体结构.
Control valve spool line equation before and after the valve has an important impact on pressure. Based on the finite element analysis software ANSYS, the establishment of a control valve simulation model, and the different valve spool model of a simulation analysis, come to different The influence of the spool-type line on the pressure drop before and after the valve, the stress analysis of the control valve body under the consideration of the fluid-structure interaction, the stress field concentration and the service life of the valve body can be avoided through the coupling field analysis, and the optimal design Body structure.
