摘　　要：通过数值模拟计算方法,对波纹管四通金属密封球阀中波纹管的刚度和应力进行模拟计算。在20℃和500℃两种工况下,根据所施加的不同轴向力,计算波纹管的刚度以及应力,与行业标准的刚度和应力计算相比较,最终确定波纹管的设计要求。不同温度下的刚度位移,所计算的密封预紧力均满足球阀密封力要求,为波纹管球阀的在线使用提供了技术支持。The stiffness and stress of bellows in bellows four-way metal sealing ball valve are simulated by CFD.According to the different axial forces imposed,Calculate the stiffness and stress of the bellows at 20℃and 500℃.The calculated stiffness and stress of the bellows are compared with the stiffness and stress calculation of the industry standard,finally determine the design requirements of the bellows.Under different temperature stiffness displacement,the sealing preload calculated meet the ball valve sealing force requirements.It provides technical support for on-line use of bellows ball valve.
