Overall Design of Electric Butterfly Valve
The Overall Design Structure Of The Electric Butterfly Valve System. The Frequency Conversion Governor Is Used To Directly Adjust The Speed Of The Motor, With High Speed Control Accuracy, And Multi-Level Speed Control Can Be Implemented To Adapt To Various Working Conditions Of The Butterfly Valve, And The Energy Saving Effect Is More Significant.
At Present, The Driving Force Of Most Electric Devices Is A Three-Phase Asynchronous Motor, Which Is Characterized By High Output Shaft Speed, While The Speed Required By The Output Shaft Of The Electric Device Is Relatively Low, So It Must Be Decelerated By The Main Transmission Mechanism. Most Of The Main Transmission Mechanism Adopts Two-Stage Reduction Of Worm, Worm And Spur Gear, And The Stroke Switch Of The Valve Is Controlled By A Mechanical Counter. The Composition Of The Mechanical Torque Limiting Mechanism And This Type Of Driving Device Are Complicated In Structure, Large In Size And Mass, Expensive, And The Worm Gear Transmission Efficiency Is Very Low.
The Main Transmission Mechanism Of This Design Adopts Harmonic Gear Transmission, Which Has The Characteristics Of Large Transmission Ratio, Smooth Transmission And High Efficiency, Which Makes The Transmission Mechanism Small In Size And More Compact In Structure. The Stroke Control Mechanism Adopts The Cam Type Stroke Control Mechanism, Which Can Not Only Achieve Control Accuracy, But Also Has A Simple Structure For Easy Adjustment. The Control Of The Entire Electric Valve Is Controlled By A Programmable Controller, Which Is Widely Used In Various Industries With Its Complete Functions, Flexible Application, Convenient Operation, Easy Maintenance, Stability And Reliability.
