Step by step direct acting solenoid valve

Principle: it is a kind of principle combining direct action and pilot type, when there is no pressure difference between the inlet and outlet, after power on, the electromagnetic force directly lift the pilot small valve and the main valve closure piece upward in turn, the valve opens.

Principle: it is a kind of principle combining direct action and pilot type, when there is no pressure difference between the inlet and outlet, after power on, the electromagnetic force directly lift the pilot small valve and the main valve closure piece upward in turn, the valve opens. When the starting pressure difference is reached at the inlet and outlet, after electrification, the electromagnetic force pilot small valve, the pressure in the lower chamber of the main valve rises, and the pressure in the upper chamber falls, so as to use the pressure difference to push the main valve upward; When power off, the pilot valve using spring force or medium pressure to promote the closure, moving down, so that the valve closed.Features: it can operate in zero pressure difference or under vacuum and high pressure, but with large power, it must be installed horizontally.

In the bistable solenoid valves, the valve core located in the middle position is an iron body, and a permanent magnet is placed outside the valve core, as shown above. When working, the valve core produces a stable magnetic field and moves with the change of the external electromagnetic field. The driving circuit of the bistable solenoid valve is shown in the figure below. The sinusoidal wave is screened by the zero detection circuit to send the positive and negative pulses to the CPU, and the CPU is counted and allocated. For a period of time, the CPU only sends the negative pulse of sinusoidal wave positive and half cycle to the optocoupler, which triggers the post-stage SCR through the optocoupler, thus obtaining several positive polarity pulsating direct current in the electromagnetic valve coil, making the electromagnetic valve spool move in one direction. Similarly, during another period of time, the CPU only sends the positive polarity pulse of sinusoidal wave for negative half cycle, after the inverting phase is negative polarity pulse, and then triggers the post-stage thyristor, thus obtaining the negative polarity pulsating dc current in the coil, making the electromagnetic valve core move in another direction, thus realizing the bistable solenoid valves conversion.

The operation of bistable solenoid valve
2018-10-22
Bistable solenoid valves power supply pulsating 120V direct current, can be positive or negative. When the pulsating dc voltage of different polarity is applied to the solenoid coil, the spool will move in different directions. When power is stopped, the spool will stop at the end of the movement. There is only body and coil inside the bistable sol... Bistable solenoid valves power supply pulsating 120V direct current, can be positive or negative. When the pulsating dc voltage of different polarity is applied to the solenoid coil, the spool will move in different directions. When power is stopped, the spool will stop at the end of the movement. There is only body and coil inside the bistable solenoid valve, so the volume is smaller than that of unistable solenoid valve. In addition, when the spool is in any state, no power is required, so the power consumption is very small. View Details
