摘要
利用ANSYS有限元程序,对阀门制造厂设计的核安全二级气动球阀进行力学分析。分析中考虑的载荷有自重、内压、接管极限载荷、地震,分析后按照ASME规范和AP1000堆型核级球阀采购技术规格书的要求进行评定。结果表明,该气动球阀的结构设计满足ASME规范和相关技术规格书的要求。
This paper analyzed the mechanics of a nuclear safety class Ⅱ pneumatic ball valve designed by a valve manufacturer,with ANSYS finite element program.The loads considered in the analysis included gravity,internal pressure,nozzle limit load and earthquake.After the analysis,the paper evaluated the valve according to the standard of ASM and technical specifications of AP1000 nuclear class valve.The calculations showed the design of the pneumatic ball valve can meet the requirement of ASME regulations and related technical specifications.
