摘　　要：为分析油罐自力式液位控制阀主阀关阀过程,对阀芯运动过程中的受力进行分析并建立微分方程,得出关阀过程中阀芯的速度及加速度公式,分析了关阀速度与阀门工作压力、节流孔大小、阀芯内腔平均直径的关系。借助Fluent软件对关阀过程中阀门的速度场和压力场进行研究,并进一步分析了阀芯受力。研究结果对于主阀结构的优化及锥阀阀芯结构的设计具有参考意义。In order to study the shutoff process of high level valve for oil tank, the formula of thevelocity and acceleration of the valve element, which is inferred from the analysis of forces executingon valve and differential equation, based on which the relationship between working pressure, orificesize, valve element lumen mean diameter and shutoff velocity of valve element were analyzed.Software Fluent was used to simulate the velocity and pressure field during the shutoff process. Fm-theranalysis of the force executing on valve element was done, which is of good value for the majorizationof valve structure and the design of valve element of cone valve.
