Three-way valve is mainly used to change the flow direction of the medium, so it in addition to the import of A, export B, and the reversing port C, the ordinary valve is not equipped with the function of changing the flow direction of the medium.In its working process, the valve opens the medium to enter the valve from A, and flows out of the valve through b. when the bypass needs medium to flow in, the actuator turns 90°, the valve core reverses, the medium A enters and C leaves. When the pipeline does not need medium to flow in, the actuator turns 90° again, and the valve closes and cuts off the medium.
Three-way valve body has three mouths, one in two out, (left into, right and under) and common valve is different at the bottom of an outlet, when the internal valve core in different positions, the export is different, such as the valve core in the lower part, left and right interlinked, such as the valve core in the upper part, the right outlet is blocked, left and under the mouth through.Because the left mouth and the right mouth are not in a horizontal line.When high - speed emergency disconnection occurs, the valve is closed and the water supply is bypassed.Three-way valve according to the fluid action mode is divided into confluence valve and shunt valve, confluence valve has two inlet, confluence from an outlet outflow.The shunting valve has one fluid inlet, which flows out from two fluid outlets after shunting.
1. When the three-way valve is used in the control system that requires fluid matching, it can reduce the installation cost and space because it can replace both an air-opening control valve and a air-closing control valve.
2. the three-way valve can also be used in the place of bypass control, such as one flow needs to pass through the heat exchanger heat exchange, another flow does not need to pass through the heat exchanger heat exchange, when the three-way valve is installed in front of the heat exchanger to use the shunt three-way valve, when the three-way valve is installed in the heat exchanger to use the confluence three-way valve.Because the three-way valve installed in front of the heat exchanger flows through the liquid has the same temperature, so the leakage is small, installed in the three-way valve after the heat exchanger flows through the liquid has different temperature, the expansion degree of the valve core and valve seat is different, so the leakage is large.Normally, the temperature difference between two liquids should not exceed 150 degrees.
3. three-way valve has two spool and seat structure similar to the two-seat valve, but in the three-way valve, a spool and seat between the flow area increases, the other spool and seat flow area decreases.And the flow area between two spool and valve seat in two-seat valve is increased or decreased at the same time.
4. three-way valve air open and close, can only be achieved by selecting the positive action and reaction of the actuator, and in the two-seat valve air open and close can be directly through the body or valve core and valve seat back to achieve.
