[Chemical Knowledge]:Working principle diagram of electric three-way valve

The electric three-way valve is an electric control valve with complex structure and diverse functions. Electric three-way valve is usually composed of valve body, actuator, controller, sensor and other parts. When working, the actuator controls the opening and closing of the valve through the controller, so that the fluid medium is divided, combined and adjusted in the valve body.
the working principle of the
electric three-way valve is similar to that of the traditional valve, it has a higher degree of automation and intelligence. Under normal circumstances, the electric three-way valve is closed. When the valve needs to be opened, the actuator will receive the control signal and start to work, and the fluid medium in the valve will begin to flow.

Specifically, the electric three-way valve has a variety of working modes to choose from, including positive opening, positive closing, negative opening, and negative closing modes. In the positive open mode, the opening direction of the valve is the same as the flow direction of the fluid medium, that is, from the port to enter, from the B and C ports to go out; in the reverse open mode, the opening direction of the valve is opposite to the flow direction of the fluid medium, that is, from the B and C ports to enter, from the port to go out. In the positive and negative closing modes, the valve openings are all closed, and the fluid medium cannot pass through the valve.

In practical applications, the most commonly used electric three-way valve is the flow regulation mode. By adjusting the stroke of the actuator by the controller, the flow rate of the fluid medium can be adjusted. At this time, the actuator will accurately control the opening of the valve according to the electrical signal sent by the controller, so that the flow rate of the fluid medium is kept within the set range.

In order to better help readers understand the working principle of the electric three-way valve, this article provides a detailed operation flow chart, including the source of the control signal, the working diagram of the actuator, the direction of the fluid medium flow and so on. The reader can understand the actual operation process of the electric three-way valve through the diagram, so as to better understand the characteristics and application scenarios of the valve type.

electric three-way valve has important application value in fluid pipeline. It can realize the diversion, confluence and adjustment of fluid medium, so as to ensure the normal operation of the pipeline. At the same time, due to the characteristics of automation and intelligence, the electric three-way valve can also greatly improve the degree of automation and efficiency of the pipeline. I hope this article is helpful for readers to understand the working principle of the electric three-way valve.
