Brief introduction of the rotary valve
Directional control valve is to have two or more flow form and two or more oil control valve in the direction of the mouth to realize the communication of the hydraulic oil flow, cut off and the reversing, and pressure unloading and sequential control valve. It can be divided into the manual reversing valve, electromagnetic reversing valve, electro-hydraulic directional control valve, etc.
A, It is also called the Chris valve, the valve has the multidirectional tunable channel, which can timely change the flow direction.
Work with outside the valve drive transmission mechanism rotating drive shaft, take turn to shake arm, start the valve plate, the working fluid and sometimes from left entrance leads to the bottom of the valve outlet, and sometimes from right entrance to transform towards the lower export, realized the purpose of flow cycle transformation.
The switch valve is widely used in petroleum, chemical production, the most commonly used in the synthetic ammonia gasification system. In addition, the reversing valve can also be made the structure of disc type more occasions for small flow rate. Only when the job rotation handwheel transform of the working fluid flow through the disc.
Categories of the rotary valve
(1) motor reversing valve, motor reversing valve is also called the trip valve.
(2) the electromagnetic directional valve, electromagnetic directional valve is to use the electromagnetic attractive control valve core displacement direction control valves.
(3) electro-hydraulic directional control valve: the electro-hydraulic directional control valve is a complex valve.which is made up of electromagnetic directional valve and liquid reversing valve.¡¡¡¡
(4) manual reversing valve:the manual reversing valve is pushed by hand lever operated valve core displacement direction control valves.
