全启式安全阀

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。

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 .
