Introduction to the performance characteristics of the three-way valve
Three-way valve summary: The three-way valve has 3 inlets and outlets connected to the pipeline, which is equivalent to two single-seat valves combined into one. According to the mode of action, it is divided into two types: converging valve and diverging valve.
The three-way valve has the following characteristics:
(1) The three-way is modified from single-seat and double-seat valves, and uses the valve core itself to guide. When replacing the air opening and closing, the actuator must be replaced.
(2) When the three-way valve is working, one path is fully closed and the other path is fully open. The force when closed is similar to that of a single-seat valve.
(3) Due to the small unbalanced force of the small diameter, when Dg≤80, the converging valve can be used in the diverging situation.
(4) The spool of the three-way valve is the same as the sleeve of the sleeve valve. Its throttling area has two types: large window and small hole (jet type). The latter has (a) X type structure (b) Q type The structure reduces noise and reduces resonance.
