摘　　要：　给水管网漏损与管网压力有着直接关系。以管网漏损量最小为目标函数,建立了自控阀优化控制的模型,实例考核结果表明,采用自控阀控制管网漏损在理论上是可行的,但要经济上也可行则需满足一定的条件,即当管网中有高位水池或水塔而无调节水泵时,用自控阀控制管网漏损才收效显著。Leakage loss in water supply network is directly related to the system pressure. By taking the minimum leakage loss as objective function, the model was set up for optimization control of auto-control valve. The case study indicated that it is theoretically feasible for the auto-control valve to control leakage, but some requirements must be satisfied to achieve economical feasibility, that is, only when there is elevated water tank and no adjustable pump in the network, can the auto-control valve work well in control of leakage.
