摘要
耐海水腐蚀冲刷蝶阀是核电循环水冷却系统的重要装备。为满足恶劣的工况条件及核电行业对安全生产的严格要求,开发一种新型核电海水蝶阀,并根据海水的腐蚀与冲刷特性进行合理选材。采用ANSYS Workbench有限元分析软件,建立核电海水蝶阀的有限元模型,分析1.5倍设计压力载荷下蝶板的形变及应力分布情况。仿真结果表明,经优化设计的海水蝶阀结构合理,蝶板的形变与应力均满足设计要求。
Butterfly valve of high resistance to seawater corrosion is an important equipment of circulating cooling water system of nuclear power plant. To satisfy the work conditions and the stringent criterion, a kind of new nuclear butterfly valve is developed. The valve material is chosen according to the seawater corrosion. ANSYS workbench is applied to build the finite element model of nuclear butterfly valve for deformation and stress analysis of the butterfly plate under 1.5 times pressure of design load. The simulation results show that the optimization design of butterfly valve is reasonable, and the deformation and stress satisfy the criterion.
