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 Pro / E software introduced from PTC Company of the United States was used to calculate the three-dimensional finite element of the anti-pump valve seat on the S G I workstation to determine the stress distribution and deformation of the valve seat. By analyzing the influence of many factors on the strength and sealing performance of the anti-air valve seat, the structure of the anti-air valve seat is optimized and improved to not only reduce the equivalent stress value in the high-stress area but also to make the sealing of the anti-air valve seat and the valve more reliable .
