Abstract

The invention discloses an electromagnetic valve control circuit which comprises an electromagnetic valve, regulating devices and a main control circuit; the main control circuit and the regulating devices are connected through a change-over switch; the regulating devices control the electromagnetic valve through the main control circuit; and the main control circuit comprises an external closed loop control system circuit and an internal reference circuit. The electromagnetic valve control circuit has the beneficial effects that: a plurality of regulating devices are connected with the main control circuit, so that the different levels of operation of an operator are convenient, and the circuit has a simple design, low cost and reliable performance. The design of the reference circuit ismore convenient to calibrate and operate by the operator. Due to the design of the external closed loop control circuit, the control circuit has strong anti-interference capability, good stability and high reaction speed.

Description

technical field [0001] The invention relates to a control circuit, in particular to a Hall feedback control circuit for an electromagnetic valve. Background technique [0002] There are many kinds of solenoid valves on the market, and the control method is nothing more than manually adjusting the control voltage of the solenoid valve and adding a controllable constant current voltage. By manually controlling the working voltage of the solenoid valve, the rotation angle of the solenoid valve can be controlled, and then the air flow can be controlled. Manual control has poor precision, low efficiency, and is difficult to locate accurately. At the same time, the interference of the power supply is large, the airflow fluctuates greatly, and the maintenance cost is high. The mechanical handle is used to adjust the pressure division, and the control method is susceptible to interference and the adjustment handle is vulnerable. In the process of adjustment, the speed is slow, due ...
