1, Overview  

Electric regulating louver valve is mainly composed of valve body, louver plate, valve shaft, connecting rod mechanism, driving device and other main components, tilt louver valve and electric actuator matching use, accept adjustment or transfer of unit signal, automatic control valve opening and complete the adjustment task.  Widely used in building materials, metallurgy, mining, electric power and other industrial departments to automatically adjust or control the medium flow in the pipeline.  The electric shutter valve is matched with the electric actuator, which has the advantages of small opening and closing torque, sensitive action, reliable performance, large diameter and light weight.  Electric shutter valve is widely used in metallurgy, building materials, electric power, petrochemical, light industry and other industrial departments of fan, air conditioner, electric dust and a variety of large pipelines, can be on the dust, gas, electric or manual adjustment and cut off.  

2, The characteristics of  

Electric tilt louver valve louver, multi-shaft structure, shaft seat assembly structure, easy maintenance.  The sealing packing is made of flexible graphite, the sealing pressure is adjustable, the valve plate streamline structure, the flow resistance is small, the flow is uniform, the opening and closing moment is small, the action is sensitive, the performance is reliable.  

3, The working principle  

Electric actuator through the crank, connecting rod to drive the valve leaf shaft synchronous rotation to control the valve opening, regulating pipeline flow.
