摘要
根据ASMEⅧ中提出的壳体上由接管外载荷引起的局部应力按WRC107和WRC297公报进行计算的要求,对球形阀体阀颈的局部应力进行了分析与计算以及应力分类与叠加,并按第三强度理论进行强度校核。
In accordance with the requirements of ASME VIII that the local stress caused by outer pipe load on the shell should calculate according to the requirement of the WRC107 and WRC297 communi- que, the paper gives the local stress analysis and calculation for the neck of ball valve and stress classi- fication and superposition, and makes intensity check according to the third strength theory.
