摘　　要：主给水流量闭环调节阀是快中子增殖堆二回路给水系统重要设备之一,该调节阀的作用将下游蒸汽发生器的压力和流量稳定在整定值,所以该调节阀的流量特性设计尤为重要,是保证核电站正常运行的前提。依据该调节阀的实际运行工况参数、使用要求和设计原则,设计了该调节阀的流量特性,并通过试验法对该流量特性进行了验证。The main feed water flow closed-loop regulating valve is one of the important equipment in the second loop feed water system of fast neutron breeder. The function of the regulating valve will stabilize the pressure and flow of downstream steam generator at the set value,so the design of the flow characteristics of the regulating valve is particularly important,which is the premise to ensure the normal operation of nuclear power plant. In this paper,the flow characteristics of the regulating valve are designed according to the actual operating parameters,operating requirements and design principles of the valve,and the flow characteristics are verified by the test method.
