一、用途
Ⅰ.Application
本系列蝶阀适用于冶金、矿山、建材、石化、造纸、纺织等行业的工业管道中。它对气体半流体等管道中的介质按不同的信号,改变其流量的大小,从而达到自动调整风量,实现自动控制。体阀采用优质钢板焊接结构,具有传动轻巧灵活,密封性能好,开闭时间短,切断速度快,能可靠的杜绝事故的发生。
This series butterfly valve is suitable to use in the industry pipe of metallurgical, ore building material. Paper textile and so on, Accord to the different signal in the pipes of the gas half fluid medium. Change the flow volume, and adjust the fan volume automatically. It can realize automatic control. The valve is used good welding structure. It is characterized by light, nimble good sealing, short open time, fast speed broken and dependable.
二、结构及工作原理
Ⅱ.The structure and Working principle
1、电动蝶阀由电动执行机构和蝶阀组成,有关电动执行机构作用原

1、The electric butterfly valve posed of electric execute structure and butter fly valve. The relative electric execute. Working
principle and main is refer to the operation manual of electric executor.
2、电动蝶阀按作业方式可分为电开式和电关式两种。电开式:无信号电流时,阀处于关闭位置,随着信号电流从0~10A或从4~20mA的增加,阀从关闭位置逐渐转向全开位置。电关式:无信号电流时,阀处于开位置,随着信号电流从0~10A或从4~20mA的增加,阀从全开位置逐渐转向关闭位置。在一般情况下,用户不提出要求,按电关式调整出厂。
2、The electric butterfly valve have open and close type according to the way. Electric and open type: When there is signal current, the valve is in close position. With the addition of signal current from 0~10A or 4~20A, the val
