Electric butterfly valve flange is usually made of angle stroke electric actuator (0~90 ° part of the rotary valve) and whole through a mechanical connection, through a common component after installation. And has the advantages of simple structure, small volume, light weight, only by a few parts. But only can be rotated 90 ° rapid opening and closing, simple operation, the valve has a good flow control characteristics.

Introduction
电动法兰蝶阀通常由角行程电动执行机构（0~90°部分回转）和蝶阀整体通过机械连接，经过安装调试后共同组成。
Electric butterfly valve flange is usually made of angle stroke electric actuator (0~90 ° part of the rotary valve) and whole through a mechanical connection, through a common component after installation.
蝶阀的蝶板安装于管道的直径方向。在蝶阀阀体圆柱形通道内，圆盘形蝶板绕着轴线旋转，旋转角度为0°~90°之间，旋转到90°时，阀门则牌全开状态。
The direction of the diameter of the butterfly valve butterfly plate installed in pipeline. Cylindrical channel in the butterfly valve, the disc-shaped butterfly plate around the axis of rotation, rotation angle of 0 ° ~90 °, the 90 ° rotation, the valve is full state license.
蝶阀结构简单、体积小、重量轻，只由少数几个零件组成。而且只需旋转90°即可快速启闭，操作简单，同时该阀门具有良好的流体控制特性。

电动法兰蝶阀结构简单、体积小、重量轻，只由少数几个零件组成。而且只需旋转90°即可快速启闭，操作简单，同时该阀门具有良好的流体控制特性。法兰蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体时唯一的阻力，因此通过该阀门所产生的压力降很小，故具有较好的流量控制特性。蝶阀有弹密封和金属的密封两种密封型式。弹性密封阀门，密封圈可以镶嵌在阀体上或附在蝶板周边。
Electric butterfly valve flange has the advantages of simple structure, small volume, light weight, only by a few parts. But only can be rotated 90 ° rapid opening and closing, simple operation, the valve has a good flow control characteristics. Flange butterfly valve in the fully open position, the disc thickness is only when the medium flows through the body resistance, thus generated by the valve pressure drop is small, it has a good flow control characteristics. Butterfly valve with elastic metal seal and the seal two kinds of sealed type. Elastic sealing valves, seals can be mounted on the body or attached to the disc periphery.
采用金属密封的阀门一般比弹性密封的阀门寿命长，但很难做到完全密封。金属密封能适应较高的工作温度，弹性密封则具有受温度限制的缺陷。
Metal sealed valves are generally higher than the flexibility of the valve seal and long life, but it is very difficult to completely seal. Metal seal can adapt to high temperature, flexible seal is restricted by temperature defects.
如果要求蝶阀作为流量控制使用，主要的是正确选择 阀门的尺寸和类型。蝶阀的结构原理尤其适合制作大口径阀门。蝶阀不仅在石油、煤气、化工、水处理等一般工业上得到广泛应用，而且还应用于热电站的冷却水系统。
If asked to use as a flow control valve, the main choice is the right size and type of valve. Butterfly valve structure principle is particularly suitable for production of large diameter valves. Butterfly not only widely used in oil, gas, chemical, general industrial water treatment, but also used in thermal power plant cooling water system.
常用的蝶阀有对夹式蝶阀和法兰式蝶阀两种。对夹式蝶阀是用双头螺栓将阀门连接在两管道法兰之间，法兰式蝶阀是阀门上带有法兰，用螺栓将阀门上两端法兰连接在管道法兰上。
Common butterfly valve wafer type butterfly valve and flange type butterfly valve two. Wafer type butterfly valve is the valve connection between two pipe flanges with bolts, flange type butterfly valve is a valve with a flange, on both ends of the valve in the pipe flange connection flange bolt.
