烟气管道防爆电动蝶阀

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、烟气管道防爆电动蝶阀结构及工作原理 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理,使用维护等参阅电动执行机构说明书。 1、The electric butterfly valve is composed 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 valve is from close position to open position. Electric and close type: When there is no signal current, the valve is in open position. With the addition of signal current from 0~10A or 4~20A, the valve is from open position to close position. Generally the valve leave the factory in electric and close type. 作用原理:从操作器来的信号电流,进入电动执行机构,使其输出一个相应的角位移,带动连杆,使阀板有一个相应的角位移。由于阀板在阀体内转动,改变流通截面,达到对介质流量的调节。电动蝶阀在设计上采用阀板在关闭状态时有一始角10°,因此,在关闭时,其泄漏面积较小,故其具有较低的泄漏量。当信号电流因故中断时,可将电动执行机构的电动机“旋钮”拨在手动位置,然后将手轮连轴向外拉出,用手转动手轮。由手动转入自动运行时,必须将“旋钮”拨到“自动”位置,并将手轮推入。 Working principle: The signal current from the operator enter in to electric execute structure. Make it output a suitable rotated angle movement. With the pole, the valve plate have a suitable rotated angle movement. Because the valve plate is rotated in valve body, change the flow section. Adjust the medium flow volume. When the electric butterfly valve is used valve plate, there is a start angle (10 degree)in design. So the leakage area is smaller, the leakage volume is lower. When signal current is broken, put the button of electric execute structure in hand position. Then the hand wheel is drawn out. Drive the hand wheel in hand. When the hand position change into automatic position, put the button on automatic position. 三、烟气管道防爆电动蝶阀安装使用与维护 Ⅲ、Installation and maintenance 1、电动蝶阀最好安装在水平管道上,如需安装要垂直管道上,用户在订货时应注明。 The electric butterfly valve had better install the horizontal pipe. If the client request to install the vertical pipe. 2、烟气管道防爆电动蝶阀使用在振动的情况下,安将时应加支承和加固。 When the big mouth butterfly valve is used in vibrated condition, it should be support and strength. 3、电动执行机构的调整、使用与维护见电动执行器说明书。 The adjustment of electric executor structure, operation and maintenance see the operation manual of elector. 四、主要外型及连接尺寸 Ⅳ.The main outline and connection size
 
烟气管道防爆电动蝶阀由温度传感器、温度控制板、电动执行机构、防爆蝶阀构成。
适用传热系统软件出水温度操纵;根据自动调节热力设备一次侧蒸气或水介质的总流量来确保二次侧的出水温度维持在设置温度。当温度传感器的精确测量温度超过预设值时,温度控制板输出操纵数据信号使电动蝶阀调小或关掉一次侧的介质总流量;当温度传感器的精确测量温度低于预设值时,温度控制板输出操纵数据信号使电动蝶阀放大,扩大一次侧的介质总流量,进而使二次侧出水温度做到设定目标温度。
 
烟气管道电动防爆蝶阀构成
1、控制板:控制板具备PI、PID调整作用,操纵多控制回路操纵,作用多种多样,可完成液体总流量、工作压力、压力差、温度、环境湿度、露点温度和空气指数的操纵。
2、电动执行机构:电动式脚踏式和电动式油压式,含有手动式和自动调节作用,调整灵巧,关闭力大,总流量特点可调式(线形等百分数)。电动式油压式电动执行机构带关闭电源全自动校准维护作用,可接受0-10V或4-20MA的数据信号并含有阀位意见反馈作用。
3、防爆电动蝶阀为单座反方向阀,螺栓连接或活套法兰,油路板材料为黄铜、紫铜、灰铁、灰铸铁、铸钢件等,规格DN10.。.DN150,介质温度-25.。.350℃。适用循环系统管道冷藏水,底压开水、日常生活开水、髙压开水、海面、滚油、和蒸汽的调整、线形好、可调式比大、密封性严实、耐热、防气蚀。总而言之,可依据客户的不一样应用工作状况,挑选高性价比的、适合的、平稳靠谱的闸阀系列产品。
4、温度传感器:精确测量介质温度,类型齐备。按安装部位可分成:浸入式温度传感器、整合式温度传感器、风列管式温度传感器、房间内温度传感器、户外温度传感器等各种类型。
