摘　　要：对3.5MPa边界阀法兰密封———柔性石墨金属波齿复合垫片密封的泄漏进行了密封失效分析,并提出了改进方案,解决了垫片密封短期失效问题。Under given pressure （3.5MPa） conditions, metal skeleton of flexible graphite corrugated metal gaskets occurred the seal leakage in the boundary valve. The failure analysis and improvement was proposed, which solves the problem of short - term failure of the gasket sealing.
