Electric butterfly valve (Butterfly Valve Electronic), is a kind of electric valve and electric valve, electric butterfly valve connection mode is mainly: flange and clamp type, according to the transmission mode can be divided into manual, gear drive, pneumatic, hydraulic and electric, is an important area of industrial automation control unit.
Structure and working principle of electric butterfly valve:
Usually from the angle of the electric actuator (0~90) and butterfly valve as a whole through the mechanical connection, after installation and debugging.
According to the action pattern classification: switch type and regulation type.
Switching mode is to direct the power supply (AC220V or other power level of power) through the switch is the reverse direction to complete the switch operation.
The regulation is based on the AC220V power supply as the power to receive the industrial automation control system design parameters of 4~20mA (0~5 and other weak control) signal to complete the adjustment action.
Main purpose of electric butterfly valve:
Control of flow, pressure and temperature in various industrial automation production line. For example: electric power, metallurgy, petrochemical, environmental protection, energy management, fire control system, etc..
Electric butterfly valve product features:
1, opening and closing convenient fast, easy, fluid resistance is small, can often operate;
2, simple structure, small size, light weight;
3, to transport slurry, accumulation of fluid in the pipe outlet at least;
4, low pressure, can achieve a good seal.
5, electric butterfly valve adjustment performance is good.
