Electric butterfly valve (English Name: electronic butterfly valve) is a kind of electric valve and electric control valve. The connection mode of electric butterfly valve mainly includes flange type and clamp type. According to the transmission mode, it can be divided into manual, gear transmission, pneumatic, hydraulic and electric. It is an important executive unit in the field of industrial automation control.
Structure and working principle of electric butterfly valve:
It is usually composed of angular stroke electric actuator (0 ~ 90 ° partial rotation) and butterfly valve through mechanical connection, and the clip type butterfly valve is jointly composed after installation and debugging.
According to the action mode, it can be classified into switch type and regulation type.
Switch mode is to directly connect the power supply (AC220V or other power level power supply) to complete the switch action through the switch forward and reverse guidance.
The regulating type uses AC220V power supply as the power supply to receive the preset parameter value of 4 ~ 20mA (0 ~ 5 and other weak current control) signal of industrial automation control system to complete the regulation action.
Main uses of electric butterfly valve:
Various industrial automation production pipeline flow, pressure, temperature control. For example: electric power, metallurgy, petrochemical, environmental protection, energy management, fire protection system, etc.
Features of electric butterfly valve:
1. Easy to open and close, labor saving, small fluid resistance, can be operated frequently;
2. Simple structure, small volume and light weight;
3. The slurry can be transported, and there is little liquid accumulated at the pipeline mouth;
4. Under low pressure, good sealing can be achieved.
5. The electric butterfly valve has good regulation performance.
电动蝶阀（英文名：electronic butterfly valve）是一种电动阀和电动调节阀。电动蝶阀的连接方式主要有法兰式和卡箍式。按传动方式可分为手动、齿轮传动、气动、液压和电动。它是工业自动化控制领域的一个重要执行单元。
电动蝶阀的结构和工作原理：
通常由角行程电动执行机构（0~90°偏转）和蝶阀通过机械连接组成，夹式蝶阀在安装调试后共同组成。
按动作方式可分为开关式和调节式。
切换方式是直接接通电源（AC220V或其他电源电平的电源），通过开关的正向和反向引导完成开关动作。
调节型采用AC220V电源作为电源，接收工业自动化控制系统4~20mA（0~5等弱电控制）信号的预置参数值，完成调节动作。
电动蝶阀的主要用途：
各种工业自动化生产流水线流量、压力、温度控制。例如：电力、冶金、石化、环保、能源管理、消防系统等。
电动蝶阀特点：
1启闭方便，省力，流体阻力小，可频繁操作；
2结构简单，体积小，重量轻；
三。浆液可以输送，管口处几乎没有液体积聚；
4在低压下，可以实现良好的密封。
5电动蝶阀具有良好的调节性能。
