摘要
文中指出一般内流式锥阀流体力分析中选用一个控制体积的不足，选取了阀腔上、下流两个控制体积，运用两次动量变化的概念，得到新的内流式锥阀液动力理论方程，为了实用方便，文中给出了一种近似计算公式。
The defect about flow force analysis of a converged flow poppet valve in the traditionaltheory is pointed out.By selecting the two control volumes of the upstream flow and down-stream flow,and using the concept of the twice vary of the monentum,a new theoretical for-mula for calculating the flow force of a converged flow poppet valve is obtained. For the con-venience of using in practice,an approximate formula is given in the paper.
