内压自封式阀门泄漏原因探讨和设计参数的选择

Discussion on leakage cause and design parameter selection for internal pressure self-sealing valve

通过对旋启式止回阀中法兰内压自封式密封副结构发生泄漏及采取修复措施失败的原因分析,阐述了为专用试验台架特定设计的阀门,应谨慎引入标准规定的有关参数。

Through the cause analysis on the leakage occurred in the internal pressure self-sealing aim structure of the cover flange for swing check, and the cause analysis on failure of repairing activities, expounds that relevant parameters regulated in the standards should be prudently cited for the specified valves designed for special test-bed.
