摘　　要：针对某型插装式高压溢流阀在试验过程中频繁出现油液泄漏的问题,通过对阀的密封结构和和试验后配合零件间的接触情况分析,发现油液泄漏是因阀的密封结构设计不合理导致零件尺寸及形位公差难于保证且毛刺不易去除所致,对密封结构进行了改进设计,并完成试验验证,泄漏问题得到了解决。In view of the frequent oil leakage of a plug-in high-pressure overflow valve during the test,through the analysis of the sealing structure of the valve and the contact between the matching parts after the test,it is found that the oil leakage is caused by the unreasonable sealing structure design of the valve,which makes it difficult to ensure the size and geometric tolerance of the parts and difficult to remove the burrs.The sealing structure is improved,The test verification is completed,and the leakage problem is solved.
