valve

The valve ,which is also named separating material machinel, is widely builing material ,metallurgy ,mining ,light industry and food industries etc.It is the ideal equipment to change flow direction of solid crystal and powder material in tiansportation system .
Structure characteristic :
The valve is weeded in fine steel and equipped with different actuators according to the different demands . It has the features of lighweight , antifiction , definite indicating direction ,handy switching and flexible operation etc.
Type I is side three-way liuzi ,type II is face three-eay liuzi ,type III is four-way liuzi .The driving types are five :
S denotes manual , D denotes eletric,Z denotes automatic ,Q denotes pneumatic and Y denotes electric hydraulic.
working pressure : 0.01mpa
suitable temperature : <300oC
suitable material specific gravity : <2.5t/m3
suitable medium : crystal, grain and powder etc

working principle
The valve is mainly made up of body ,separating plate ,transmission shaft ,bearing support ,sealing ,rocker and transmission device etc. Push the heavy hammer of manual valve and switch the flow direction according to the requirement.Command control unit of electric valve power the DT electric draw stem stem and push the rocker to rotate valve axle in order to switch medium flow direction . The automatic valve is equipped with DKJ electric actuator, which
receives and adjusts the control sign of DCS,PLC eqistasy meter or manual control sign of operating and outputs angle displacement to drive transmission shaft, then drive separating plate rotating with rocker and valve axle.The open angle of electric actuator and separating plate feeds back 0-10mA or 4-20mA DC signal. Users can control the open angle of according to the current signal to sdjust the valve.Pneumatic valve is equipped with type 10A-5 pneumatic element and pneumatic draw stem driven by double-control two-bit five-way electric control reversal valve, pushing rocker to drive the axle and plate and swith the flow direction of medium .Electric hydraulic valve is equipped with type DYT electric hydraulic draw stem; it pushes the rocker to drive axle and plate and swithch flow direction of medium and meets the requirement of working conditions.
