摘　　要：应用从美国 Ｐ Ｔ Ｃ 公司引进的 Ｐｒｏ／ Ｅ 软件，在 Ｓ Ｇ Ｉ工作站上对防气泵阀座进行了三维有限元数值计算，确定了泵阀座的应力分布和变形规律。通过分析多种因素对防气泵阀座强度及密封性的影响，对其结构进行了优化改进，不仅降低了高应力区的当量应力值，而且使防气泵阀座与阀的密封更加可靠。The value of 3D finite element of valve seat on anti gas rod pump is calculated at SG1 work station by applying the Pro/E software imported from an American company,PTC.On the basis of the above,the stress distribution and deformation law on valve seat are determined.After analyzing the effect of various factors on strength and sealing property of valve seat,the structure of valve seat is optimized and improved.As a result,not only is the stress at high stress area reduced but also the seal property between valve seat and valve is more reliable.
