The function and function of the two position two way solenoid valve

The two-position two-way solenoid valve is a step-action direct-operated solenoid valve.

According to the different open and closed states when the power is off, it can be divided into normally closed solenoid valve and normally open solenoid valve.

Normally closed solenoid valve, after the coil is energized, the armature is in the electromagnetic force.

When the pressure on the main valve cup is reduced to a certain value, the armature drives the main valve valve cup, and the main valve valve cup is opened by using the pressure difference, and the medium flows. When the coil is de-energized, the electromagnetic force disappears, and the armature resets due to its own weight. At the same time, depending on the pressure of the medium, the main and auxiliary valves can be closed tightly.

Normally open solenoid valve, after the coil is energized, due to the suction, the moving iron core moves down, the auxiliary valve plug is pressed, the auxiliary valve is closed, the pressure in the main valve cup rises, when the pressure rises to a certain value, the upper and lower pressure difference of the main valve valve cup is the same, due to the action of electromagnetic force, the moving iron core pushes the main valve valve cup down, presses the main valve seat, and the valve is closed.

When the coil is powered off, the electromagnetic suction force is zero, the auxiliary valve plug and the moving iron core are lifted upwards due to the action of the spring, the auxiliary valve is opened, and the fluid on the main valve valve cup flows away through the auxiliary valve, which reduces the pressure acting on the main valve valve cup, when the pressure on the main valve valve cup is reduced to a certain value, the main valve valve cup is pushed up by the pressure difference, the solenoid valve is opened, and the medium flows.

Hello! The function and function of the two-position two-way solenoid valve is: the power supply through the coil. Power. To achieve the on/off of the valve.

It is divided into normally open type and normally closed type.

Normally open type means: when no power is given. The two working holes of the valve body are connected.

Normally closed type means: when no power is supplied. The two working holes of the valve body are not connected.

Hope it works for you!

One input and two output: (ZC2 31) when the solenoid valve coil is energized, the first channel of the outlet medium end (2) is opened, and the second channel (3) is closed; When the solenoid valve coil is powered off, the first channel (2) at the outlet medium end is closed, and the second channel (3) is opened;

Two in and one out: (ZC2 32) when the solenoid valve coil is energized, the first channel (2) at the inlet medium end is opened, and the second channel (3) is closed; When the solenoid valve coil is powered off, the first channel (2) at the inlet medium end is closed, and the second channel (3) is opened; (Check valves must be added before the two inlets of this inner valve).

One in and one out: normally closed (ZC2 3) -- when the solenoid valve coil is energized, interface 2 leads to interface 1, and interface 3 is closed; When the solenoid valve coil is powered off, the interface 2 is closed, and the interface 1 leads to the interface 3; Normally open (ZC2 3K) When the solenoid valve coil is powered off, interface 3 leads to interface 1, and interface 2 is closed; When the solenoid valve coil is energized, interface 3 is closed, and interface 1 leads to interface 2;

The working principle of the solenoid valve: when the solenoid coil is energized, the static iron core produces electromagnetic attraction to the moving iron core to make the valve switch to change the direction of the air flow valve, which is called the magnetron directional valve, referred to as the solenoid valve, which is convenient for the realization of electric and pneumatic joint control, and can realize remote operation.

The two-position three-way solenoid valve is divided into two types: normally closed type and normally open type, normally closed type means that the gas path is broken when the coil is not energized, and normally open type means that the gas path is open when the coil is not energized.

The principle of action of the normally closed two-position three-way solenoid valve: the coil is energized, the gas path is connected, and once the coil is powered off, the gas path will be disconnected, which is equivalent to "joging".

The principle of action of the normally open two-position three-way single electronically controlled solenoid valve: the coil is energized, the gas path is disconnected, and once the coil is powered off, the gas path will be connected, which is also "joging".

The action principle of the two-position five-way double electronically controlled solenoid valve: if the positive action coil is energized, the positive action gas path is turned on (the positive action air outlet hole has gas), even if the positive action coil is powered off, the positive action gas path is still connected, and it will be maintained until the negative action coil is energized.

If the reaction coil is energized, the reaction gas path will be turned on (the reaction air outlet hole has gas), and even if the reaction coil is powered off, the reaction gas path will still be turned on, and it will be maintained until the positive action coil is powered. This is equivalent to "self-locking".

Three-way solenoid valve with two positionsIt can be widely used in life, it is relatively safe to use, and it is indispensable to understand its principle when using it, so that there can be a good way to use it in the later stage, so that the product pays more attention to safety during production, and can give every user rest assured. Let's introduce to you, what is the principle of two-position three-way solenoid valve?

What is the principle of one-two three-way solenoid valves?

1. The solenoid valve has a closed chamber and through holes in different positions, and each through hole is connected by a different oil pipe. In the center of the cavity is the valve. There are two electromagnets on both sides. Control the movement of the valve body on either side.

2. Block or leak another oil drain hole, when the oil inlet is opened normally, the hydraulic oil enters the other oil drain pipe, and the oil pressure pushes the oil cylinder. The piston moving mechanism that drives the piston rod. Mechanical properties are controlled by controlling the current in the electromagnet.

Dear, I am glad to answer for you Answer: The working principle of the two-position three-way solenoid valve: The principle of the two-position three-way solenoid valve:

The two-position three-way solenoid valve is controlled by a double coil, the power supply is turned off and the valve is opened after the coil is energized instantaneously, and the power supply is turned off and the valve is closed after the other coil is instantaneously energized. It can be left closed or open for a long time, which can make the coil last longer. It is best used in high-temperature pipes.

I hope mine can help you.
