摘　　要：介绍了一种通过采用PLC对电磁阀或切断阀实行通断控制来实现对小流量系统进行流量调节的方法,从而实现对选矿厂药剂添加等小流量系统精确、简单和低成本调节控制的目的,并列举了两个具体的应用实例以供参考交流。The paper introduces a flow control method which is achieved through opening and closing of electromagnetic valve or disconnection valve controlled by PLC, thus achieving accurate, simple and low cost control for small flow system (such as addition of agent) in concentration plant. Two concrete examples are also enumerated in this paper for reference.
