Pulse valve solenoid valve function, pulse valve solenoid valve working principle

What is pulse Valve solenoid?

By wire Change Solenoid valve The coil in the body inputs a pulse signal. The pulse valve is controlled by the output signal of the pulse injection controller and relies on the pressure of the two air chambers before and after the valve. The pressure changes cause the rubber diaphragm to flex and deform to open and close the pulse valve. The diameter of the rubber diaphragm determines the stroke size and opening and closing speed of the rubber diaphragm. The larger the diameter of the diaphragm, the larger the stroke and the better the blowing performance.

Pulse valve solenoid valve function

Generally installed in the main oil circuit or shock absorber back pressure oil circuit, at the moment when the transmission automatically upshifts and downshifts or when the lock-up clutch The oil pressure is reduced when the locking and unlocking actions begin to reduce the impact of shifting and locking and unlocking, making the vehicle run more balanced. Its function is to control the oil pressure in the oil circuit.

According to the angle of the valve inlet and outlet and the form of the air inlet, it can be divided into three types:

1. Right angle Type electromagnetic pulse valve: a diaphragm valve whose inlet and outlet are at right angles and directly controlled by electrical signals.

2. Straight-through electromagnetic pulse valve: valve body The inlet and outlet are 180 degrees apart and are directly controlled by electrical signals.

3. Submerged electromagnetic pulse valve: valve body The air inlet is submerged in the air bag and is a diaphragm valve directly controlled by an electrical signal.

Pulse valve solenoid valve working principle

Input a positive pulse signal to the coil in the solenoid valve through a wire. The working magnetic flux generated by the coil causes the moving core to attract and open the valve. When the forward pulse signal input is stopped, the moving core is released, and the moving core returns to the initial state under the action of the spring force. The valve is closed. There is also a self-maintaining type, which can be maintained even after the forward pulse input is stopped or the power is turned off. An input is required. A negative pulse signal can be reset;The working principle of the pulse solenoid valve is to use electrical pulses to convert into mechanical pulsations, making the pulsating gas powerful The energy turns into momentum and is released in a short period of time to generate huge impulse. The pulse interval controlled by PLC should be determined according to the rated gas pressure recovery time l.
