Basic knowledge and technology content of electric butterfly valve electric butterfly valve is made open-close part and the circular disc with the valve rod rotation to open and close and regulating fluid channel of a Industrial Valves. Butterfly valve is not only simple in structure, small volume of search engine optimization (seo), light weight, low material consumption, installation size is small, and the drive torque is small, easy to operate, agile, and also has good flow regulating function at the same time and closing sealing characteristics, in the field of large and medium size, the use of low and medium pressure, butterfly valve is the dominant situation of the valve. Electric butterfly valve, English name: Electronic Butterfly ) , is one of the electric valves and electric control valve, electric butterfly valve connection style important: flange and clamp, according to the driving style can be divided into manual, gear transmission, pneumatic, hydraulic and electric several, was nervous in the field of industrial initiative control unit. The structure and working principle of electric butterfly valve, usually by the Angle of travel electric implementing agencies ( 0 ~ 90 ° rotation) And butterfly valve groups through mechanical connection hebei personnel test center network, after installation and debugging. According to the movement pattern classification are: switching type and external regulation. Switch type is directly connected to the power supply ( AC220V or other power levels of power) By the movements of the switch is, anti-missile has completed switch. External regulation is AC220V power as power, receiving industrial initiative in the system default parameter values of 4 ~ 20 ma ( 0 ~ 5 and other weak current control) A standard led to complete the regulating action. The basic knowledge of electric butterfly valves, electric butterfly valve technology knowledge important application: all kinds of industrial initiative in the production of pipe flow, pressure, temperature control. For example, electric power, metallurgy, petrochemical, environmental protection, energy management, fire fighting system, etc. Electric butterfly valve product characteristics: 1, convenient opening and closing agile, energy saving, fluid resistance small, can often operation; 2, simple structure, small volume, light weight; 3, can transport the mud, the apertures accumulated liquid at least; 4, low pressure, can achieve good sealing. 5, electric butterfly valve regulation performance excellence. I company 'valve' all history with many years of production experience butterfly valve is patented and has some products application, on the basis of persist to attract foreign capital technology and use obtained municipal and users. Pneumatic butterfly valve also achieved great success
