针对矿井自动排水系统中存在的问题,提出了多级离心泵抽真空吸水系统用大流量控制阀的设计方案,对阀的组件(电动执行器、控制电路以及外壳)进行了设计,并通过试验验证了设计的抽真空控制阀能满足多级离心泵抽真空吸水系统的要求。
Aiming at the existing problems in mine automatic drainage system, the design scheme of large flow control valve for vacuum suction system of multistage centrifugal pump was proposed. The valve components (electric actuator, control circuit and enclosure) were designed and tested It is verified that the designed vacuum control valve can meet the requirements of multistage centrifugal pump vacuum suction system.
