摘　　要：在低温阀门设计中经常用到皮碗密封结构进行动密封,结构设计不合理容易造成泄漏,通过有限元分析对结构设计进行改进,提高密封可靠性。结果表明,改进后的密封结构效果良好,达到预期目的。The sealing structure of the leather bowl is often used in low temperature valve design,unreasonable structure design can cause leakage easily,the structural design is improved through finite element analysis,improve seal reliability.the results show that the improved sealing structure has good effect,achieve the desired goal.

关 键 词：阀门 密封 有限元
