A solenoid valve is a device that controls the opening and closing of fluid through electromagnetic action. Among them, the 2-position 3-way solenoid valve is a solenoid valve with a small number of channels, with only two positions and three channels. So, what is its schematic diagram?

we look at the structure of the 2-position 3-way solenoid valve. It is mainly composed of valve body, valve core and electromagnet. There are three channels in the valve body, which are the inlet, the outlet and the funnel hole (also called the middle channel). When the electromagnet is energized, a magnetic field is generated, which makes the valve core move downward and break contact with the valve seat, so that the funnel hole and the outlet are connected, and the inlet and the funnel hole are disconnected. Conversely, when the electromagnet is powered off, the spool will return to the original position, making the funnel hole and the inlet connection, the outlet and the funnel hole disconnect. By means of this switch, the passage of the fluid is controlled.

Next, let's analyze the working principle of the 2-position 3-way solenoid valve. When the power supply is energized, the electromagnet begins to generate a magnetic field, causing the valve core to move downward and disconnect from the valve seat, so that the funnel hole and the outlet are connected, and the fluid can enter the valve body from the inlet, flow through the funnel hole, and then flow out of the outlet. On the other hand, when the power is cut off, the magnetic field disappears, and the valve core returns to its original position, making the funnel hole and the inlet connection, and the fluid enters the valve body from the inlet. After passing through the funnel hole, the direction of flow out becomes the outlet. In this way, the flow direction of fluids such as liquid and gas can be controlled to achieve the opening and closing functions.

So, what are the application scenarios of the 2-position 3-way solenoid valve? Normally, it can be used to control the flow of media such as gas and liquid between the two directions, such as controlling the feed and discharge of certain machines, or controlling the inlet and outlet of the heating system. In addition, in some simple industrial automation equipment, a 2-position 3-way solenoid valve can also be used to control the entry and exit of fluid.

2-position 3-way solenoid valve is a relatively simple solenoid valve, its schematic diagram is relatively simple. Through the above introduction, readers can better understand the working principle and application scenarios of the 2-position 3-way solenoid valve, to better select and use the solenoid valve.
