摘　　要：在选煤厂浮选生产中,常采用阀门调节清水流量,除模拟人工手动控制阀门开度外,对清水阀门的控制可有双重控制策略,即基于入浮浓度稳定或入浮流量稳定的调节。文章对阀门的双重控制策略进行了简要分析,并介绍了其实现的具体方法。The valve control is usually used for modulating water flow to influence the feeding quality in coal flotation.Besides of imitating manual control of valve position,there are two types of control strategies,they are based on the feeding density modulating and feeding flow modulating.The two strategies are of respective availability.The strategies of valve are briefly analyzed and the practical implement ways is introduced in the paper.
