The function of explosion-proof coils is to easily change the current applied to the electromagnetic coil during startup and maintenance when controlling the action of the solenoid valve, achieving the goal of reducing power consumption and operating costs.
The explosion-proof solenoid valve coil is composed of a winding made of enameled wire, characterized in that some of the enameled wires that make up the winding are connected in parallel with variable resistance devices. According to this structure of the winding, as a part of the winding is connected in parallel with a variable resistance device, the resistance value can be changed. During start-up and holding, while maintaining the coil performance, the current value and corresponding coil turns can be well changed. Therefore, it can ensure reliable starting power for the explosion-proof electromagnetic valve and reduce power consumption.
From the perspective of this explosion-proof solenoid valve control method, the current supplied to the valve coil is controlled by a variable resistor device. During the start-up stage of the solenoid valve, a high current value is applied to the explosion-proof coil. After a certain period of time, when the core iron is attracted to the fixed iron core and enters the holding stage, the current applied to the coil is in a low current value state, which is a good work control measure to reduce power consumption. Furthermore, the explosion-proof electromagnetic coil is powered by a power source to the winding. By providing an input voltage to the coil, the current supplied to the valve coil can be controlled, achieving reliable operation and maintenance of the explosion-proof electromagnetic valve. This can reduce power consum
