摘　　要：提出了一个通过管网水力计算在管网中实现自控阀合理布置的方法。将自控阀的局部水头损失引入管网水力计算当中,计算自控阀在每个管段不同开启度条件下对管网压力变化的影响程度,提出管网影响度的概念。并以实例管网进行验证,得出了自控阀在管网中合理布置的一般原则。研究证明,该方法具有实用、简便、易于操作等特点,非常有利于在供水企业中的应用。This paper presented a new approach to realize the optimal distribution of auto-control valves in water supply network by hydraulic calculation. Firstly, the local headloss of the auto-control valve was introduced to the pipe network's hydraulic calculation. Then, the valve was supposed to be set on each pipe with different opening degree, following which the influencing degree on network was calculated under each situation. Last, this approach was tried on an example water supply network, and a general principle for the optimal distribution of auto-control valve was obtained. Through application it could be found that this approach was practical, easy to operate and suitable for application to water corporations.
