摘　　要：利用CFD数值仿真软件Fluent,对船用海水淡化装置膜片式负荷调节阀的流动特性进行了数值模拟,计算和分析了不同弹簧刚度条件下,调节阀开度及流量随进口压力变化的特性,为合理选择弹簧刚度,从而满足不同调节特性的要求提供了设计依据和指导.The flow characteristic of the diaphragm load regulating valve for marine fresh water generator is simulated by using the CFD code of Fluent software. The open degree and mass flow rate varying with the inlet pressure under different spring rigidity is calculated and analyzed. It offers the design considerations and guidance for selecting the stiffness of spring to satisfy different regulating properties.
