Furthermore, ANASYS stress and deformation analysis of the ball with complicated structure is made, and the requirements of sealing and fire-proof and switching of the valve are considered in the structural design.

• 对其中结构复杂的球体进行了ANSYS应力和变形分析计算,在结构设计中,充分考虑了球阀的密封、防火、启闭传动及制造工艺的要求。 该产品最终按照APISpec6D(20版)《管线阀门规范》进行试验验收,其各项指标均达到设计要求。
