How does the three-way ball valve work?

Jan 21, 2019

The three-way ball valve is a relatively new type of ball valve. It has some unique features unique to its structure. For example, the switch has no friction, the seal is not easy to wear, and the opening and closing torque is small.

The working principle of the three-way ball valve determines that the valve body has three ports, one in two or two in one out; unlike the ordinary valve, when the inner valve core is in different positions, different outlets are turned on, such as when the valve core is in the lower part, The left and right are connected, and the lower outlet is closed; if the spool is at the upper part, the lower left is connected, and the right outlet is closed.
The working principle of the three-way ball valve is as follows:
Open: 2 ports of intake, 4 ports of exhaust, push the two pistons to move to both sides, while compressing the spring, the output shaft rotates counterclockwise;
Close: When the air is lost or loses power, the spring pushes the two pistons together to move toward the center, and the output shaft rotates clockwise.
