摘　　要：为了获得低背压条件下非能动自动泄压阀内部流动特性。计算中使用计算流体动力学(CFD)方法建立了主阀的流道模型,得到了不同工况下各部位的单相以及两相流场分布,获得了主阀的阻力特性,为阀门的设计提供支持。The purpose of this paper is to obtain the ADS pressure relief valve and the main valve of the recirculation valve.The flow path model of the main valve is established by using the Computational Fluid Dynamics(CFD)method in the calculation,and the single-phase and two-phase flow field distributions of each part under different working conditions are obtained to get the resistance characteristics of the main valve.
