The improved FMECA method analysis the safety valve by combining the method of the fault tree and the stochastic petri nets, that provides a whole new way of thinking for the quantitative assessment to the safety valve, and it has a prominent practical significance.

1、

Considering the result of improved FMECA and the conversion relationship between the fault tree and stochastic petri nets, the paper takes a reliability analysis to the spring full-open safety valve and gets some reliability date in the last.

根据改进FMECA分析结果以及故障树与随机Petri网之间的转换关系，将弹簧全启式安全阀的故障树转换成相应的随机Petri网，通过结合相关的失效数据进行定量的可靠性分析。
