With the continuous development of modern science and technology, solenoid valve as one of the most important components in automatic control system, widely used in various fields, especially in machinery and equipment, safety systems, transportation equipment and food processing industries.

and in the solenoid valve, two three way solenoid valve is a common type. Its structure and working principle are simple, but it can play an important role in practical applications. Below we will through the detailed analysis of the two three way solenoid valve schematic diagram, together to explore its technical characteristics.

1. solenoid valve structure principle

two-way solenoid valve, that is, there is an inlet and two outlets of the solenoid valve. Inside it, it is composed of iron core, control module and coil. Among them, the iron core is the most important part of the solenoid valve, with strong magnetism, which can attract the tripping on the iron core to open or close the valve. The

control module is another important part of the solenoid valve. It can control the switching of the coil to change the magnetic state of the iron core. When the coil is turned on, the iron core will enter the magnetic attraction mode and the valve will be opened; when the coil is powered off, the iron core will be separated from the magnetic attraction and the valve will be closed.

2. Solenoid Valve Working Principle

In actual work, solenoid valves are usually divided into normally open and normally closed. This difference is mainly reflected in the initial position of the valve. When the two-position three-way solenoid valve is normally open, its valve is initially closed and will open only when the circuit is on and off; when the two-position three-way solenoid valve is normally closed, the opposite is true, and the valve is initially open.

When current passes through the coil, the magnetic field generated can attract the iron core to move and push the valve open. At this time, the medium entering through the inlet port will be guided by the valve into one of the outlets. When the current is interrupted, the iron core loses its magnetism and returns to the position where the valve is closed. At this time, the medium is guided to another outlet by the valve.

3. solenoid valve application field

two-position three-way solenoid valve has a wide range of applications. They are mainly used in the following fields:

1. Air compressor: In the air compressor, the two-position three-way solenoid valve It is used to control the cooling water flow of the evaporator.

2. Water treatment facilities: In water treatment facilities, the two-position three-way solenoid valve is used to control the water flow during food processing.

3. Automotive industry: In the automotive industry, two-position three-way solenoid valves are used to control the flow of coolant.

two-position three-way solenoid valve as an important automatic control components, has become an indispensable technology in various fields. Through the in-depth analysis of its structure and working principle, I believe we have a more comprehensive understanding of the two-position three-way solenoid valve, I hope this article can be helpful to our future work and study.
