摘　　要：分析了卸荷阀的结构和工作原理,先导阀作为卸荷阀卸荷的关键控制部件,先导阀流场数值特性直接影响到卸荷阀整体的工作性能。运用流体仿真软件Fluent对先导阀进行运动流场数值仿真,对比了不同压差情况下,先导阀内部压力分布云图、速度矢量分布图及流体流线图。研究结果对矿用卸荷阀先导阀在流道结构的优化上有一定的理论指导意义。This paper Analyzes unloading pilot valve structure and working principle. The pilot valve is critical control components of unloading valve, numerical simulation of pilot valve is a direct impact on whole of unloading valve performance. I use the Fluent as fluid simulation software to get the Simulation of pilot valve. To make contrasts of pressure, velocity distribution and flow chart in differential pressure. The research results has some theoretical significance for optimizing flow structure of unloading pilot valve.
