Abstract: For improving valve system reliability and failure disposal time, carry out its reliability research. By sorting out the fault data of valve system in high speed wind tunnel from different information platform, a cost function is established with the product of failure frequency and average disposal time. Different kinds of valve faults are sorted according to the cost function. Measures such as redundancy design, procurement of spare parts, technical improvement and arrangement design can be made based on the analysis results. The results show that the research could be qualified to increase the MTBF of the valve system, shortened the average time for handling the system failure, and effectively enhance the reliability.
