Working principle of pulse solenoid valve
A positive pulse signal is input to the coil in the solenoid valve body through the wire, and the working magnetic flux generated by the coil causes the moving core to pull in and open the valve. When the input of the forward pulse signal is stopped, the moving core is released, and the moving core returns to the initial state under the action of the spring force. Input negative pulse signal to reset;
The working principle of the pulse solenoid valve is to use the pulse of the electrical appliance to convert into mechanical pulsation so that the powerful energy of the pulsating gas becomes momentum to release a huge impulse in a short time. determine.
Uses: generally installed in the main oil circuit or the back pressure oil circuit of the shock absorber, the oil pressure is reduced at the moment of automatic transmission upshift and downshift, or at the beginning of the locking clutch unlocking and unlocking action to reduce the change The impact of gear and lock unlocking makes the operation of the vehicle more balanced.
The role of the pulse solenoid valve is to control the size of the oil pressure in the oil circuit.
Characteristics of pulse solenoid valve:
Because the pulse solenoid valve has the characteristics of low power consumption and low voltage, it can be used with a smart card water meter. It is an indispensable actuator for the automatic control of water in the intelligent water meter system.
Pulse solenoid valve structure:
The valve is composed of an excitation coil and a magnetic steel pilot valve. The main valve adopts a special rubber diaphragm structure. Due to its unique design, the valve has the advantages of low power consumption, short instantaneous energization time, wide operating pressure range, etc. It is an ideal actuator for automatic control of tap water.
Working principle of pulse solenoid valve:
When the coil is energized instantaneously, the electromagnetic force moves the armature. When the coil is de-energized, the armature is self-retained by permanent magnetism. At this time, the medium pressure in the upper part of the diaphragm in the main valve cavity passes through the pressure relief hole to make the diaphragm up and down. Poor, under the effect of inlet medium pressure, lift the diaphragm, the main valve opens. When an instantaneous reverse current is given to the coil, the armature moves in the opposite direction, cutting off the pressure relief hole, and the medium bursts into the upper part of the diaphragm through the main valve balancing hole, sealing the main valve port.
