| 摘 要： | 对水压锥闽流场进行了CFD解析，解析结果以可视的速度场和压力场分布给出。针对锥阀过流特性的分析结果对闽芯结构进行改进，将阀芯锥面与柱面直接相接改为圆弧过渡，改进后的结构明显减小了压力损失和阀内最小负压值，同时降低了阀芯所受轴向液动力。

| Abstract: | CFD simulation is applied to the flow field inside water hydraulics poppet valve, the results are given by visualizing pictures of the velocity and pressure field. The structure of the poppet surface is optimized to be arc-linked after field character analysis for poppet valve.The optimum structure obviously reduces the pressure drop,minimum negative pressure and axis fluid force on poppet. |
