Abstract

The invention discloses an electromagnetic valve power supply circuit and an adjusting method thereof, and belongs to the technical field of power supply control. The method specifically comprises the steps of carrying out real-time adjustment of the output voltage of an electromagnetic valve constant-current drive circuit according to parameter information of the electromagnetic valve constant-current drive circuit, and carrying out the refining processing of the output current of the electromagnetic valve constant-current drive circuit. The electromagnetic valve power supply circuit and the adjusting method thereof have the advantages that: stable constant current can be rapidly and finely output, the current adjusting precision is high, the reverse voltage generated by an electromagnetic valve is small, and the service life of an electronic device is prolonged; and the system loss can be reduced to the greatest extent, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power supply control, in particular to a solenoid valve power supply circuit and an adjustment method thereof. Background technique [0002] As a basic component of automation, solenoid valves are widely used in various industrial scenarios. For example, in nuclear reactors, the operation of starting, stopping, power regulation, and accident reverse insertion of the reactor is realized by controlling the solenoid valve to adjust the position of the control rod. When the solenoid valve is energized, its coil generates electromagnetic force to lift the closing member from the valve seat to open the valve. When the valve is opened, the armature continues to absorb, the stroke distance is reduced to the minimum, and the electromagnetic force reaches the maximum. When the armature is in the state, the extra power passes through. Coil resistance is converted into heat energy, and the long-term accumulation of h...
