| Abstract: | Through the cause analysis on the leakage occurred in the internal pressure self-sealing trim 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. |
