摘　　要：用ANSYS软件对水压锥阀的流场进行分析,将解析结果以可视化的速度场和压力场给出,从而针对锥阀过流特性的分析结果,对阀座和阀芯的结构进行改进———将阀座与阀芯由直角相接都改为圆弧过渡;改进结构后,明显减小了压力损失和阀内的最小负压值。研究结果对设计低消耗、低噪声水压锥阀有一定的指导作用。The flow field inside the water hydraulic poppet valve was analyzed by using the software of ANSYS, then the visualizing pictures of the velocity and pressure field were given. The structure of the poppet valve＇ s core and the poppet valve＇ s seat was optimized to be arc-linked at their direct connection according to analyzing result of the flow characteristic. The result shows that the optimum structure obviously reduces the pressure drop and the minimum negative pressure greatly. The research can give a guide for designing low consumption, low noise water hvdraulic poppet valves.
