摘　　要：研究钢厂废煤气流场作用下大型压力控制阀的稳压问题,分析了影响压力稳定的结构因素,利用Pro/E建立了控制阀的几何模型,采用CFX进行流场计算,ANSYS进行结构计算,并利用两者间的数据交互平台传递流场压力载荷和结构位移数据,实现了流固耦合数值仿真计算。计算结果表明,阀芯结构及开度是影响压降的重要因素,且外接管与控制阀通径之比越大时阀前阀后压降越小。研究结果为控制阀结构的优化设计和测试分析提供了重要依据。Pressure stability of large-scale control valve was investigated under flow field formed by coal gas. In order to analyze effect factors of pressure, geometry model of control valve was provided. Fluid-solid coupling simulation was accomplished by using CFX and ANSYS workbench in flow field and numerical calculation of structure, with a coupling bench which can transfer fluid pressure and structure displacement. The results show that valve structure and opening are important factors which influence the pressure stability, the bigger the path ratio of connection to valve is and the smaller the pressure drop is, which could provide reference for the optimal desian and testing.
