摘　　要：分析了先导式安全阀流道结构几何参数对其排放性能的影响,并采用CFD商业软件FLUENT对先导阀主阀流场进行数值模拟,得出了先导式安全阀排放性能与流道结构的关系及其不同流道结构下流场的分布和排量系数的仿真曲线,为先导式安全阀排放性能的研究提供一定的理论依据。The paper analyzes the effection of some main geometrical flow parameters of the pilot operated safety valve on capability of discharge, and then simulates the flowing of main valve by the CFD software-Fluent. Finally, gets the distribution of internal flow field and the simulated curve by numerical simulation, the connection between the capability of discharge and flow structure, which provides some theoretic direction for the future jobs of the pilot operated safety valve.
