摘要
通过简述一种由三偏心蝶阀结构演变而来的四偏心蝶阀结构,进而通过有限元分析软件,得出三偏心蝶阀密封圈与该四偏心蝶阀密封圈的应力分布云图,进行比对、浅析两种结构后,对该四偏心密封副结构的密封性能有了更好的了解。
This paper introduces a four-eccentric butterfly valve structure which is evolved from three-eccentric butterfly valve structure. Then, through the finite element analysis software, the stress distribution cloud of the three-eccentric butterfly valve ring and the four-eccentric butterfly valve ring is obtained. On the two structures, the four eccentric seal sub-structure of the sealing performance has a better understanding.
