全焊接管线球阀锥形阀体的分析与设计

Analysis and Design of Conical Valve Body of All-welded Pipeline Ball Valve

介绍了全焊接管线球阀锥形阀体的薄膜应力与壁厚计算过程,阐述了其边界效应,分别对有折边与无折边的锥形阀体设计规则加以说明,最后通过计算案例加以验证,为锥形阀体的设计提供了参考。

Introduced the calculation process of membrane stress and wall thickness of conical valve body of all-welded pipeline ball valve,expounds its boundary effect,explains the design rules of the conical valve body with flanged and without flanged respectively,and verifies them through calculation cases,which provides a reference for the design of conical valve body.
