Abstract

The present invention relates to the field of mechanical equipment and, more particularly, to a drainage control system for water-air separator. The drainage control system for water-air separator provided by the invention comprises a control unit, an air-water sensor and an electromagnetic valve. One end of the air-water sensor is connected with the bottom of the water-air separator and the other end is connected with the electromagnetic valve. The air-water sensor comprises two shells with openings at both ends. Two independent electrodes are arranged on the end face of the shells; each electrode is connected with a conductive wire, and the conductive wire is connected to the control unit. During operation, as the liquid level increases, the two electrodes are turned on, generating an electric signal to the control unit; the control unit electrifies and turns on the electromagnetic valve to discharge the liquid. When the level drops below the electrodes, the electric signal disappears; the control unit cuts off and closes the electromagnetic valve circuit to achieve automatic drainage. With a simple structure, high degree of automation, high sensitivity, and high reliability, the system also achieves high drainage efficiency.
