摘要
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.
The plug molded line equation plays an important part in the pressure drop of the control valve.Based on the finite element analysis software ANSYS,a control valve simulation model was established,the plugs with different molded lines were analyzed,and the effects of different molded lines on the pressure drop were presented.At the same time,the stress analysis of the control valve body was shown by considering the fluid-structure interaction.This study provides theoretical guidance for shortening the optimization design cycle of the control valve.
