This solution guarantees a compact size and a more light system on the valve.- When the actuator is manual operated it can be locked in Open/Closed position.- Actuator versions for low temperature and high temperature applications allow to operate respectively until temperatures of -50°C and +150°C, thanks to proper kind of lubrication and material for the gaskets.The maintenance should be done by Actuatech trained personnel only.This instruction manual contains important information regarding the Actuatech manual override actuator operation, installation, maintenance and storage.Please read carefully before installation and keep it in a safe place for further reference.Modification reserved.

Pneumatic rotary actuatorDouble acting and spring return The 2051QT pneumatic rotary actuators are ofthe rack and pinion type where the linear kineticenergy is directly transformed into a “quarter turn” operation with a constant output torque over the full stroke.Both double acting and spring return actuators have twin pistons horizontally opposed and incorporate piston guides to ensure correct contact between the rack and pinion at all pressures.High quality materials are employed throughout the construction and the compact design is readily fitted to any type of ball valve, butterfly valve or other equipment requiring efficient pneumatic actuators.The actuator is suitable for mounting a full range of accessories, such as limit switches, solenoid valves, positioners and manual override gearbox.Extruded aluminium alloy, gold anodizedPressure die cast aluminium alloy, black epoxy coated Carbon steel, zinc platedType 6519NAMUR Solenoid valve Type 8792/93 Positioner SideControlType MV2650Ball valve Type 1062QTPosition feedbackType VV2670Butterfly valveFunctional principleDouble acting actuator (DA)Counter clockwise output operation is achieved by inserting pressure into Port ‘A’, to force piston apart thus rotating the actuator pinion counter clockwise. During the operation, air from the outer chambers is exhausted through Port ‘B’. Clockwise output operation is achieved by reverse of the above and inserting pressure into Port ‘B’.Single acting actuator (SR)Pressure applied to Port ‘A’ will cause the inner chambers to be pressurized, forcing the pistons outward to compress the springs. The pinion is rotated counter clockwise. Upon release of pressure through Port ‘A’ the springs will exert pressure to close the pistons and rotate the pinion clockwise rapidly. This action will often be used to close a 90oturn valve in shutdown mode.Pistons assembly variationsArrangement of springs for single acting actuatorActuator direction of rotation can be changed by switching both the pistons in accordance to the below diagramSprings can be added or removed according to torque requirement.

气动阀门执行器由于现在的控制方式和手段越来越多，在实际工业生常和工业控制中，用来控制气动执行机构的方法也很多，常用的有以下几种。

(一)利用PLC来控制的系统PLC在控制系统中的应用越来越广泛，由于本方案是在OMRON的PLC 上面作的开发，所以以OMRON的PLC来作介绍。

硬件组成：1台计算机，1套PLC(包括CPU，I/O模块，ID212，OC224，AD003模块)，2个继电器，2个电磁阀，1个气动阀门执行器。

其组成原理为：由PC机通过RS-232串口通讯连接OMRON的PLC，对PLC进行编程和监控。

PLC的I/O模块分别接入输入、输出信号，其中输入模块连接到阀门上的两个位置传感器，通过PLC的输入模块ID211的指示灯亮的先后顺序来显示阀门的开关状态。

输入模块接收两路阀门检测脉冲输入，即脉冲A与脉冲B。

在运行状态下，脉冲A输入时指示灯A亮，脉冲B输入时指示灯B亮。

输入顺序为AB，表示开阀。

输入顺序为BA表示关阀。

阀门检测脉冲A和B信号必须部分叠加，否则不能正常检测阀门开度。

通过PLC的输出模块OC225控制两个继电器，继电器具有两组常开常闭输出触点，1组为开阀输出触点，1组为关阀输出触点。

开阀时，当阀门开度大于或等于所设阀门限位值时开阀输出触点动作，阀门开度小于所设阀门限位值时开阀输出触点动作，发明开度小于所设阀门限位值时开阀输出触点复位。

关阀时，当阀门关到零位且21s内无脉冲输入时关阀输出触点动作；若21s内有脉冲输入，则延时21s关阀输出触点动作。

通过继电器的吸合来控制两个电磁阀的开关，电磁阀打开后，便可以控制气动阀门执行器使得阀门做相应的开阀或关阀动作。

同时接近传感器把阀门的开关情况再传送到PLC中，并同要求的阀门开度作比较，直到符合要求为止。

自动归零与自动调满：控制系统具有自动归零与自动调满功能，当阀门开度小于归零范围值或阀门开度距满量程小于满度调节范围值，且时间大于或等于所设值稳定时间值时，PLC自动控制阀门进行归零或自动调满。

电动执行器又称阀门电动装置,它是在不同行业领域的称谓,在工业管道阀门行业称之为阀门电动装置,在仪表行业称之为电动执行器,但现在业内已没有很明确的区分,本文所涉及到的关于称谓问题将统一称之为电动执行器.阀门在工业管路控制中是经常使用的重要设备,电动阀门随着工业自动化的发展,因其动力源容易取得,且一般情况下无需维护的优点,比起气动、液动等不同驱动方式的设备使用更为普遍.在工业场合电动阀门必需具有更高的可靠性和安全性,当阀门能保证性能和寿命的情况下,电动阀门的安全性与可靠性取决于电动执行器,因此电动执行器的性能、控制水平是电动阀门整机技术水平的综合表现.所以在电动执行器选型时除必需考虑的一些基本要素外,对其提出合理的技术要求才能使电动阀门价值实现最大化.电动执行器的类型很多,不同类型和功能的电动执行器与阀门配套后都可称之为电动阀门,但往往在设计、选型的过程中只重视阀门的参数忽略或没有明确电动执行器的相关要求,这样不仅使电动阀门发挥不出最佳的性能,而且在安装、调试、使用过程中也会带来不必要的麻烦,甚至给生产造成严重的后果.本文将针对电动执行器选型考虑的要点进行说明,并对目前智能电动执行器的相关功能做简单介绍,它将是当今乃至将来工业自动化控制发展所需的主流产品.本帖交易内容一电动执行器选型考虑要点一、根据阀门类型选择电动执行器阀门的种类相当多,工作原理也不太一样,一般以转动阀板角度、升降阀板等方式来实现启闭控制,当与电动执行器配套时首先应根据阀门的类型选择电动执行器.1．角行程电动执行器转角<360度电动执行器输出轴的转动小于一周,即小于360度,通常为90度就实现阀门的启闭过程控制.此类电动执行器根据安装接口方式的不同又分为直连式、底座曲柄式两种.a直连式：是指电动执行器输出轴与阀杆直连安装的形式.b底座曲柄式：是指输出轴通过曲柄与阀杆连接的形式.此类电动执行器适用于蝶阀、球阀、旋塞阀等.2．多回转电动执行器转角>360度电动执行器输出轴的转动大于一周,即大于360度,一般需多圈才能实现阀门的启闭过程控制.此类电动执行器适用于闸阀、截止阀等.3．直行程直线运动电动执行器输出轴的运动为直线运动式,不是转动形式.此类电动执行器适用于单座调节阀、双座调节阀等.二、根据生产工艺控制要求确定电动执行器的控制模式电动执行器的控制模式一般分为开关型开环控制和调节型闭环控制两大类.1．开关型开环控制开关型电动执行器一般实现对阀门的开或关控制,阀门要么处于全开位置,要么处于全关位置,此类阀门不需对介质流量进行精确控制.特别值得一提的是开关型电动执行器因结构形式的不同还可分为分体结构和一体化结构.选型时必需对此做出说明,不然经常会发生在现场安装时与控制系统冲突等不匹配现像.a分体结构通常称为普通型：控制单元与电动执行器分离,电动执行器不能单独实现对阀门的控制,必需外加控制单元才能实现控制,一般外部采用控制器或控制柜形式进行配套.此结构的缺点是不便于系统整体安装,增加接线及安装费用,且容易出现故障,当故障发生时不便于诊断和维修,性价比不理想.b一体化结构通常称为整体型：控制单元与电动执行器封装成一体,无需外配控制单元即可现实就地操作,远程只需输出相关控制信息就可对其进行操作.此结构的优点是方便系统整体安装,减少接线及安装费用,容易诊断并排除故障.但传统的一体化结构产品也有很多不完善的地方,所以产生了智能电动执行器,关于智能电动执行器后面将再做说明.2．调节型闭环控制调节型电动执行器不仅具有开关型一体化结构的功能,它还能对阀门进行精确控制,从而精确调节介质流量.因篇幅有限其工作原理在此不作详细说明.下面就调节型电动执行器选型时需注明的参数做简要说明.a控制信号类型电流、电压调节型电动执行器控制信号一般有电流信号4～20mA、0～10mA或电压信号0～5V、1～5V,选型时需明确其控制信号类型及参数.b工作形式电开型、电关型调节型电动执行器工作方式一般为电开型以4～20mA的控制为例,电开型是指4mA信号对应的是阀关,20mA对应的是阀开,另一种为电关型以4-20mA的控制为例,电开型是指4mA信号对应的是阀开,20mA对应的是阀关.一般情况下选型需明确工作形式,很多产品在出厂后并不能进行修改, 奥美阀控生产的智能型电动执行器可以通过现场设定随时修改.c失信号保护失信号保护是指因线路等故障造成控制信号丢失时,电动执行器将控制阀门启闭到设定的保护值,常见的保护值为全开、全关、保持原位三种情况,且出厂后不易修改.奥美阀控生产的智能电动执行器可以通过现场设定进行灵活修改,并可设定任意位置0~100%为保护值.三、根据阀门所需的扭力确定电动执行器的输出扭力阀门启闭所需的扭力决定着电动执行器选择多大的输出扭力,一般由使用者提出或阀门厂家自行选配,做为执行器厂家只对执行器的输出扭力负责,阀门正常启闭所需的扭力由阀门口径大小、工作压力等因素决定,但因阀门厂家加工精度、装配工艺有所区别,所以不同厂家生产的同规格阀门所需扭力也有所区别,即使是同个阀门厂家生产的同规格阀门扭力也有所差别,当选型时执行器的扭力选择太小就会造成无法正常启闭阀门,因此电动执行器必需选择一个合理的扭力范围.四、根据所选电动执行器确定电气参数因不同执行器厂家的电气参数有所差别,所以设计选型时一般都需确定其电气参数,主要有电机功率、额定电流、二次控制回路电压等,往往在这方面的疏忽,结果控制系统与电动执行器参数不匹配造成工作时空开跳闸、保险丝熔断、热过载继电器保护起跳等故障现像.五、根据使用场合选择外壳防护等级、防爆等级1．外壳防护等级外壳防护等级是指电动执行器的壳体防外物、防水等级,以字母IP后加两位数表示,第一位由1～6表示防外物等级见表一,第二位由1～8表示防水等级见表二.表一、第一位数字代表的防外物等级数字防护等级简要说明型号含义0 无防护省略不标该防护特征时,无专门的防护.1 防护直径＞50mm的固体能防止直径超过50mm的固体异物进入壳体内,人体某一大面积部分如手但对有意识的接触并无防护.2 防护直径＞的固体能防止手指或类似物,直径超过12mm长度不超过80mm的固体异物进入壳体内.3 防护直径＞的固体能防止直径大于的工具、电线等异物进入壳体内.4 防护直径＞的固体能防止直径大于1mm的固体异物进入壳体内.5 防尘不能完全防止尘埃进入壳体内,但进入量不足达到妨碍设备正常运行.6 尘密无尘埃进入表二、第二位数字代表的防水等级数字防护等级简要说明定义0 无防护省略不标该防护特征时,无专门的防护.1 防滴垂直滴水无有害影响.2 15°防滴设备与垂直线成15°角以内时,垂直滴水无有害影响.3 防淋水与垂直线成60°以内的淋水无有害影响.4 防溅水任何方向溅水无有害影响.5 防喷水任何方向冲水无有害影响.6 防海浪猛烈海浪或强烈喷水时进入外壳水量不至于达到有害影响.7 防浸水浸入在规定压力的水中经规定的时间后,进入外壳水量不至于达到有害影响.8 防潜水能按制造厂规定的条件长期潜水,其技术条件由制造厂规定. 2．防爆等级在可能出现爆炸性气体、蒸汽、液体、可燃性粉尘等而引起火灾或爆炸危险的场所时,必需对电动执行器提出防爆要求,根据不同的应用区域选择防爆形式和类别.防爆等级可通过防爆标志EX及防爆内容来表示参考爆炸性环境用防爆电气设备GB3836－2000.防爆标志内容包括：防爆型式+设备类别+气体组别+温度组别防爆型式：根据所采取的防爆措施,可分为本质安全型、隔爆型、增安型、正压型、浇封型、充砂型等.它们的标识如下表三.表三、防爆形式及标志防爆型式防爆型式标志防爆型式防爆型式标志本质安全型

内部电路检测接入交流电源的相序,通过逻辑运算实现自动纠错,不管怎么接都能按正确的转向工作.四、电源缺相保护三相电机一但缺相将会使电机损坏,传统电动执行器一般不具备缺相保护.智能电动执行器对三相电源进行检测,能在缺相的时候及时进行保护.需要注意的一个事实是,绝大多数的电机缺相是在电机运行时发生的,而一般的缺相检测只能检测电机静态下的缺相.奥美阀控生产的智能电动执行器能在动、静态下实时检测缺相是否存在,一但缺相发生将及时进行保护,通过屏幕显示,发出报警信号.五、超强自诊断功能电动执行器不管运行与否,一但被接通电源时就必需能自行诊断检测,当诊断出故障时操作将被禁止,并通过液晶显示屏显示各故障报警信息,并将信号输出给控制系统,这样对设备的安全、可靠不只增加了一层保险,也缩短排除故障的时间,使故障诊断实现智能化,这是传统产品所不具备的功能.六、可修改的参数设定传统电动执行器一般出厂后参数是不可改的,智能型电动执行器彻底改变了这种局限性,它通过内部程序实现设定,可随时进行参数的修改,不管是初装还是使用过程中都可进行修改,使得设备发挥其强大的灵活性.七、非侵入隔离密封传统电动执行器现场操作按钮或旋钮一般采用惯通轴,所以密封性能较差,智能型电动执行器一般采用非侵入式设计,操作按键与内部电路完全隔离,使得密封问题得到彻底的解决.实现了免开盖设定、操作、查询.八、现场总线控制当一个工厂使用更多的电动阀门时,如何更好的实现集中控制并与自动化控制系统相适应,总线技术解决了这个问题,当电动执行器与上位机现实总线控制时,可以不必再采用传统的多电缆控制方式.智能电动执行器采用标准接口RS485、RS232进行通讯,并将信号与处理器电路光电隔离,确保了电动执行器的安全运行.电动执行器实现总线控制方便用户利用计算机、组态软件和I/O模块来构建经济高效的控制系统.关于智能电动执行器的功能还很多,因篇幅有限这里只简单介绍以上几点.电动执行器因其采用电力驱动的优点,并能现实其他驱动装置所不能实现的控制功能,广泛应用于石油、化工、水电、船舶、钢铁、冶金、能源、轻纺、食品、医药、城市给排水等工业领域.。
