The principle of the vacuum solenoid valve to manipulate the flow coil

There are many kinds of stainless steel solenoid valves. Different vacuum solenoid valves function as automatic control systems in different parts. The most common ones are direct-moving vacuum solenoid valves. Leading vacuum solenoid valves. This product. Valves. Direction Pressure regulating valve. Variable speed pressure regulating valve.

Then first talk about the principle of vacuum solenoid valve:

The vacuum solenoid valve has already closed the cavity and opened a hole in a different part. Each hole is connected to a different oil pipe. The piston rod is in the middle of the cavity, and there are two flow coils on both sides. It encounters the magnet electromagnetic coil electric body. Which party is going to be impressed? The charging and discharging oil inlets are different according to the fitness exercise that the gate valve is opened or closed. The oil inlet is always open, and the gear oil will enter a different oil discharge pipe. The working pressure promotes the piston rod of the hydraulic cylinder, the piston rod pushes the hydraulic cylinder, and the hydraulic cylinder pushes the organization. It manipulates the thermal motion of molecules according to the amount of current in the regulating flow coil.

From the basic principle of vacuum solenoid valve can be divided into three categories

1. Move the vacuum solenoid valve immediately

Basic principle: During the normally closed test plug-in, the magnet coil creates magnetic field force, which lifts the open component from the high-pressure gate valve to open the gate valve; when the power is off, the magnetic field force subsides, and the torsion spring presses the open component on the high-pressure gate valve. Open the gate valve. (The reverse of on and off)

Features: It can work normally under vacuum pump, negative pressure and zero pressure, but the diameter generally does not exceed 21mm.

2. Gradually move the vacuum solenoid valve

Basic principle: It is a basic principle of close combination of immediate fitness exercise and dominant type. When there is no pressure difference between the entrance and exit, plug in and the magnetic field force will immediately turn off the hydraulic control valve and the main pump. The components are mentioned above. The gate valve opens. When the inlet and outlet have operating pressure difference, the electromagnetic induction will lead the return valve after plugging in, the working pressure in the lower cavity of the main pump will increase, and the working pressure in the thoracic and abdominal cavity will decrease, and then the pressure difference will be used to push the main valve up; when the power is turned off, The hydraulic control valve uses the force of the torsion spring or the working pressure of the material to promote the closing of the component, and moves downward to close the gate valve.

Features: In the case of zero pressure difference or vacuum pump, high pressure can also work, but the output power is relatively large, so it must be installed in a level.

3. Leading vacuum solenoid valve

Basic principle: When the power is plugged in, the magnetic field force opens the guide hole, and the working pressure of the chest and abdomen is rapidly reduced, and a high pressure difference is generated around the guide hole. The liquid working pressure promotes the opening of the component to move up, and the gate valve opens. When the switching power supply is disconnected, the force of the torsion spring will open the main hole, and the working pressure of the channel will quickly close the gate valve around the inner cavity according to the buried hole to produce a low voltage and high pressure difference. The working pressure of the liquid pushes the opening member down. , Open the gate valve.

Features: Small size, low functional loss, high liquid working pressure range limit, can be installed at will (need to be customized), but must meet the liquid pressure difference standard.
