| 摘 要： | 对三偏心金属蝶阀密封面接触问题进行了非线性有限元分析,阐明了其理论依据。数值模拟过程中,充分考虑了轴向偏心、径向偏心、角偏心的设计参数对密封面密封比压的影响,以DN 300口径、PN 5 MPa工作压力的三偏心金属蝶阀为例,得到其密封时的应力分布,对满足一定压力下“双向零泄漏”三偏心蝶阀的结构优化有指导意义。

| Abstract: | The sealing contact analysis of tri-eccentric butterfly valve was discussed by nonlinearity finite element method,and the theory of the method was clarified.During the process of numerical simulated analysis,the effects of axi-eccentric,radial-eccentric and angle-eccentric were considered,and the contact pressure distribution on the sealing surface of a tri-eccentric butterfly valve was gotten.All these studies are useful to the optimum design on bi-directional drop-tight tri-eccentric butterfly valve. |
