摘　　要：介绍了给水泵系统最小流量阀的技术特性以及控制原则,分析了常用最小流量阀控制方法存在的问题,提出一种改进的最小流量阀控制方案。试验结果表明:采用改进的方法控制给水泵最小流量阀,能消除流量小幅波动对阀门开度的影响,提高机组的安全经济运行水平。The technical characteristics and the control principle of minimum flow valve of the water supply pump system are intro- duced, the existing problems are analyzed, an improvement control scheme is proposed. The test results show that the minimum flow valve of water supply pump is controlled by the improvement way which can eliminate influence of small fluctuation on the valve opening and improve safe and economic operation of unit.
