摘　　要：通过对煤化工领域用快开阀门的使用工况,分析波纹管疲劳失效形式,针对此类阀门中快速动作的波纹管利用变刚度锥形波纹管设计方法,快速的对原始阀门中的金属波纹管结构方案进行调整,实现大幅增加金属波纹管使用寿命的目的,并通过理论分析和试验验证了变刚度波纹管设计方法对提高快开阀门波纹管使用寿命的有效性。By analyzing the fatigue failure form of bellows for the quick-opening valves in the coal chemical industry,the design method of variable stiffness conical bellows is used for the fast-acting bellows in such valves,and the metal bellows structure scheme in the original valve is quickly adjusted,so as to greatly increase the service fatigue life of metal bellows,and the effectiveness of the design method of variable stiffness bellows in improving the service fatigue life of the bellows of the quick-opening valve is verified through theoretical analysis and experimental testing.
