Problems solved by technology
[0003] The magnitude of the current can be realized by adjusting the voltage. To achieve dual-voltage control, the following methods are generally used: 1. Change the total resistance of the circuit through an adjustable resistor to change the current, but this method increases the power damage of the variable resistor, which is not energy-saving, and is not recommended. Use; 2. Change the size of the power supply voltage to change the size of the circuit current. This method is difficult to operate and has low reliability. It is not recommended to use

The invention discloses a control system for operation of an electromagnetic valve. The control system comprises a key module, a minimum system module, an electromagnetic valve driving module and an electromagnetic valve module, the key module and the electromagnetic valve driving module are connected with the minimum system module, and the electromagnetic valve driving module is further connected with the electromagnetic valve module; the minimum system module is used for outputting a PWM signal with a corresponding duty ratio to the electromagnetic valve driving module according to a switch of a key in the key module so as to control the electromagnetic valve driving module to open or close the electromagnetic valve in the electromagnetic valve module; the electromagnetic valve driving module comprises a first divider resistance connected with the electromagnetic valve in series, and the first divider resistance is connected with the minimum system module; and the minimum system module is also used for adjusting the duty ratio of the PWM signal output to the electromagnetic valve driving module according to the voltage values at the two ends of the first divider resistance so as to maintain the current when the electromagnetic valve works. The control system adjusts the duty ratio of the PWM signal according to the voltage of the first divider resistance, and forms closed-loop control of the current when the electromagnetic valve works.
Description
technical field [0001] The invention belongs to the technical field of electromechanical and control, and in particular relates to a control system for the operation of a solenoid valve. Background technique [0002] The solenoid valve works through the electromagnet to generate a magnetic field to attract the armature. The electromagnetic force of the electromagnet is proportional to the square of the coil current. When the solenoid valve is opened, the electromagnet needs to generate enough electromagnetic force to attract the armature and give a certain Acceleration requires a large current, and the acceleration of the armature is zero after it is fully attracted, and maintaining the original current will waste power. Moreover, the coil will generate heat after being energized, and the resistance of the coil will increase at this time, and the current will decrease, which will affect the working performance of the solenoid valve. Therefore, it is necessary to adjust the ...
