The most equivalent pressure of sealing X-ringchange section is bigger than that of sealing X-ring in the same condition.
在同等条件下，此类X形变截面密封圈比X形密封圈最大等效压力值都大。

The results show that the stress concentration is in the pointed Angle of composed face of rubber sealing X-ringchange section, mainly in inner pointed Angle that it is easy to break.
结果显示：X形变截面密封圈的应力集中部位主要集中在组合面尖角处，特别是内尖角处更易损坏。
