摘　　要：在球阀设计中,特别是在固定球阀中,碟簧是极其重要的零件,可为球阀提供密封预紧力,同时影响球阀的密封性能,是决定球阀使用寿命因素之一。因此,在球阀的设计和制造阶段需要根据实际工况条件设计碟簧的各项参数,保证球阀在使用过程中的密封性能和使用寿命。本文对球阀中的碟簧进行研究,了解碟簧对球阀性能的重要性,深入分析不同工况下碟簧的材料选择和碟簧疲劳寿命的影响因素。In the design of the ball valve,especially in the fixed ball valve,the disc spring is an extreme-ly important part,which can provide the sealing preload for the ball valve and affect the sealing per-formance of the ball valve.It is one of the factors that determine the service life of the ball valve.Therefore,in the design and manufacturing stage of the ball valve,it is necessary to design the parame-ters of the disc spring according to the actual working conditions to ensure the sealing performance and service life of the ball valve during use.In this paper,the disc spring in the ball valve is studied to un-derstand the importance of the disc spring to the performance of the ball valve,and the material selec-tion of the disc spring and the influencing factors of the fatigue life of the disc spring under different working conditions are analyzed in depth.
