船用阀门常见故障类型及可靠性试验方法研究

Research on Common Failure Types and Reliability Test Method of Marine Valves

船用阀门在实际使用当中存在各种各样的故障类型,本文对船用阀门的故障模式及故障原因进行了汇总,并结合实际使用情况给出了阀门主要故障类型。然后通过故障原因分析确认导致故障的主要应力来源,由此设计了一套用于考核船用阀门可靠性水平的试验方法,为该类产品进行可靠性考核提供参考。

Marine valves have various types of faults in actual use.In this paper,the failure modes and causes of marine valves are summarized,and the main failure types of valves are given according to the actual application.Then identify the main source of stress causing the failure by analyzing the cause of the failure.Therefore,a set of test methods for evaluating reliability level of marine valves is designed,which can provide reference for reliability evaluation of this kind of products.
