| Abstract: | The effects of the factors such as valve spring and compression agent on the service life of valves were analyzed based on the damage forms of valve sheets of large-scale compressors. By observing the metallurgic organization of the bad sheets and spring fracture, the formation and development process of fatigue cracking was analyzed. The main approaches for improving the service life of valves were presented combined with the improvement practical examples. |
