Abstract
The invention relates to a drive method for a solenoid valve, belonging to the drive of a direct current solenoid valve, comprising a voltage source, a main drive loop, an afterflow loop, a solenoid valve, a control signal, a control signal generator and a switch element of the main drive loop. A controllable afterflow switch element (3) is connected in series in the circuit belonging to the afterflow loop (4) to control on-off of the afterflow loop. Control method of the afterflow loop is characterized in that during the getting electricity period of the solenoid valve (5), the control signal (8) of the controllable afterflow switch element is regulated to make the controllable afterflow switch element (3) to be short circuited and the afterflow loop (4) is communicated, so change rate of the current is smaller when the solenoid valve is at a low power consumption maintaining stage, and intensity of the electromagnetic disturbance produced during the drive process at the low power consumption maintaining stage is reduced. During the lossing electricity period of the solenoid valve, the control signal (8) of the controllable afterflow switch element is regulated to make the controllable afterflow switch element (3) to be open circuited and the afterflow loop (4) is tripped off, so the current of the solenoid valve (5) is reduced fast and response speed of loss electricity of the solenoid valve is improved. The invention has an advantage of being suitable for drive of the solenoid valve.
