Abstract

The invention relates to a high-magnetic potential starting and low-magnetic potential maintaining type solenoid valve control module, comprising a power source, a rectifying and filtering circuit and a coil load. The high-magnetic potential starting and low-magnetic potential maintaining type solenoid valve control module is characterized by further comprising a starting circuit and a maintaining circuit. The power source is connected with the rectifying and filtering circuit; and an output of the rectifying and filtering circuit is connected with the coil load respectively through the starting circuit and the maintaining circuit. The high-magnetic potential starting and low-magnetic potential maintaining type solenoid valve control module provided by the invention is a control circuit with a self protection function, and is matched with a solenoid valve, so that alternating-and-direct current generality, wide voltage input, and energy conversation and soundless operation control canbe realized.

Description

technical field [0001] The invention relates to the field of intelligent control of instruments, in particular to a solenoid valve control module for starting high magnetic potential and maintaining low magnetic potential. Background technique [0002] As a typical low-voltage electrical product, the solenoid valve has special characteristics in its work. Take the FDF series solenoid valve widely used in the refrigeration system as an example. It has small size, compact structure, narrow working voltage range, many types of products, and difficult to control the working temperature rise. The electromagnetic system of the solenoid valve has an electromagnetic structure with variable air gap and distributed magnetic field. Therefore, during the working process, the parameters such as inductance, magnetic flux, flux linkage, voltage, current, and suction in the magnetic circuit are all changing. quantity. In the case of a large air gap, the required excitation magnetic potent...
