Abstract:  

Aiming at non standard octagonal gasket used in hydrotreating reactor. Ansys was used to calculate the contact stress on the sealing surface during the hydrostatic pressure test, and the causes of the different contact stress on each sealing surface were analyzed. The results showed that the contact stress down to the trough when the test pressure was the highest, the maximum stress on the inner side of gasket was away from the center of gasket, and the outer situation was in contrast to it. Variation of gasket sealing surface contact stress provides a reference to the analysis and evaluation of other non standard seal structure.

摘要: 针对加氢反应器顶部人孔法兰处所使用的非标八角垫, 利用 A n s y s有限元分析软件计算了其密封面
在反应器进行液压试验过程中的接触应力, 分析了各个密封面上的不同接触应力的产生原因。结果表明, 接触应力
在试验压力达到峰值的时刻降至低谷, 垫片内侧两面应力最大点出现在远离垫片中心一侧, 外侧情况则与之相反。
分析所得垫片密封面接触应力的变化规律为同种非标密封结构的分析评定提供了参考依据。
