    　　高压压缩机高压缸阀座底部截面过度处裂纹，通过有限元应力分析，发现压缩机高压气缸阀腔底径厚度不够，阀腔底径偏小，由此对阀腔底径厚度和阀腔底径进行了设计改进，改进后的气缸未再开裂。

    Abstrast: High-pressure cylinder occurred Cracks ,the Cracks start at the bottom of valve chambers transition section .From fi-nite element stress calculation, the bottom thickness of valve chamber in the high -pressure broken cylinder is not enough , and the passage section of valve chamber is also not enough , so the design of valve chamber is improved ,after improvement,Cracks to high-pressure cylinder have not occurred anymore .
