德国bach巴赫进口加长杆蝶阀概述： overview of germany bach bach imported lengthened rod butterfly valve:
蝶阀的启闭件是一个圆盘形的蝶板,在阀体内绕其自身的轴线旋转,从而达到启闭或调节的目的。蝶阀的优点有结构简单、体积小、重量轻、安装尺寸小、开关迅速。
电动蝶阀是由高精度电动执行器与对夹式蝶阀组成，执行器采用一体化结构，开关型有输入ac220v（常压）电压, 输出无源触点信号(或开关到位灯信号)，调节型有输入(dc4-20ma或dc1-5v)的控制信号及单相电源即可控制运转，精小型电动蝶阀具有功能强，体积小，轻便宜人，性能可靠，配套简单，流通能力大，特别适合于介质是粘稠，含颗粒，纤维性质的场合。电动对夹蝶阀可广泛应用于食品、环保、轻工、石油、化工、教学设备、造纸、电力等行业的工业过程自动控制系统中。
butterfly valve opening and closing parts is a disc shaped butterfly plate, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulating. butterfly valve has the advantages of simple structure, small size, light weight, small installation size, fast switching.
electric butterfly valve is composed of high precision electric actuator and wafer type butterfly valve, actuator with integrated structure, switch input voltage output ac220v (atmospheric), passive contact signal (or switch signal lamp in place), adjustable input (dc4-20ma or dc1-5v) of the control signal and the single-phase power can control the operation precision. small electric butterfly valve has strong function, small volume, light and pleasant, reliable performance, simple matching, large flow capacity, particularly suitable for medium thick, containing particles, fiber nature of the occasion. electric clip butterfly valve can be widely used in food, environmental protection, light industry, petroleum, chemical industry, teaching equipment, paper making, power industry and other industrial process automatic control system.
