| Abstract: | The operating principles and elements of an exhaust valve were analyzed with the purpose of researching valve’s failure.A reliability test-bench was designed to carry out failure-induced test based on the operating characteristics of the valve.The test results indicate that the performance decline of the seal ring is the primary reason of valve’s failure.Improved measure was put forward and a new kind of seal ring was designed.The test results validate the creditability and feasibility of this measure. |
