摘　　要：用流体仿真软件Fluent对卸荷主阀进行运动流场数值仿真,得到了不同开口度与不同压差情况下阀腔内流体的压力分布云图和速度分布云图,对仿真结果进行深入分析研究后,改进了卸荷主阀结构。对比分析改进前、后的压力分布图及速度分布图,说明改进后阀腔内流体的流场特性较改进前有了很大的改善。研究结果对矿用乳化液泵站卸荷主阀流道结构的优化有一定的理论意义。The numerical simulation of flow field in the main unloading valve for mining emulsion pump is carried out by the fluid simulation software Fluent, and creates the pressure and velocity distribution clouds of flow field under different openings and differential pressures. Through in-depth analysis and research, the structure of the valve is improved. The comparison of simulation results of original and improved valves show that the improved valve has better properties. The study has some theoretical significance for optimizing the channeling structure of main unloading valve.
