PNEUMATIC CYLINDER ACTUATORS, SERIES B

The Neles double acting and spring return B-Series piston type actuators are designed for use in both modulating control and on-off service. The series B1C and B1J are designed to ISO 5211/1 when Metso

linkages are utilized. These actuators offer an extremely long cycle life and are well suited to operate almost any type of rotary valve.

When "stay put" is the requirement, the double acting B1C series is the choice. This series is available in several sizes with torque outputs from 40 Nm to 100 000 Nm (29.5lbf ft to 73 756 lbf ft) for maximum supply pressure of 10 bar (145 psi).

If a failure mode is required, the spring return B1J series should be selected. This line offers a self-contained spring cartridge to provide failure in either the open or closed position. On butterfly valves, segmented valves and Q-ball valves, the actuator provides failure in the closed position, while a B1JA series is available when failure in the open position is required. The spring return actuators are available with a mid-range spring for 4 bar (58 psi) supply range, a lighter spring for lower supply pressure 3 bar (44 psi) range and a stronger spring for 5.5 bar (80psi) range. These actuators offer torque outputs from 50 Nm to 12 000 Nm (37lbf ft to 8851lbf ft)for maximum supply pressure 8.5 bar (124psi).

Adjustable travel stops

As with any Neles pneumatic/hydraulic actuator ,adjustable travel stops are standard for both the open and closed positions. End of stroke turning angle range is 85° to 95°. Optional travel stops 0° to 90° are also available.

Wear resistant bearings

Metal backed acetal bearings provide support on the upper and lower portions of the lever arm to reduce friction and expand the life of both the lever arm and the housing.

Corrosion resistance

The epoxy painted actuators have housings of rugged cast iron, with light-weight aluminium cylinders ano-dized for added corrosion resistance. Travel stops are stainless steel.

Self-contained spring cartridge

The springs in the B1J actuator are contained in a cartridge for added reliability and easy maintenance.

Spring to open or close capability

The standard spring return actuator on ball valve can provide spring-to-close or spring-to-open operation simply by changing the mounting position 90°. On a high performance butterfly valve, the standard unit offers spring-to-close operation. An optional B1JA model is available for spring-to-open requirements.

High-and-low temperature construction

The standard unit can be used in temperature upto 70°C (158°F). High temperature construction is availa-ble for temperatures up to 120 °C (248 °F). The standard unit can be used down to -20 °C (-4 °F). Low tempera-ture design is available down (37 lbf ft to 8851 lbf ft).

High cycle option

For applications where very fast and high sequency operation is required.

ATEX compatibility

Standard construction ATEX approved.

Oversized cylinder options

The oversized cylinders (B1C 60, 75, 602, 752) are used whenever the supply pressure is limeted, thus the actuators can achieve the required torques with lower supply pressure level.

Override options

Available override devices include a manual center-piece handle; a manual handwheel override; and a manual hydraulic override for high torque applications.

Emergency shut-down

Emergency Shut-Down (ESD) valves utilizing B1J actu-ators are offered to assure operation in the event of a fire or plant malfunction. The ESD device enables valve operational testing without cycling, see bulletin 6B21.

DOUBLE ACTING ACTUATOR, SERIES B1C

OPERATION

The linkage mechanism within the B-series actuator converts linear motion of the piston into a 90° (max. 98°) rotation of the actuator shaft. The line in the figure to the right shows torque characteristics vs. actuator shaft angle.

Max. torque is achieved at β = 0° which usually corre-sponds to the closed position of ball and butterfly valves and where max. seat torque normally appears.

Another peak is achieved at 60-80° which corresponds to the dynamic torque peak of butterfly valves. The torque’s in the table below show the minimum torque Mn at different supply pressures.

SELECTION

T o select the proper actuator for a particular valve and serv-ice, first determine the maximum operating torque that will be required for the valve from the applicable valve torque table,then refer to the appropriate mode of operation of the actua-tor in the torque output tables below and select the actuator that will, at the available air supply pressure, provide a torque output no less than the required operating torque for the valve. If in doubt, select the next larger actuator .

ACTUATOR TORQUE M n

Note:

The actuator can be used at higher supply pressures than shown in the table.

Maximum supply pressures are listed in the table on page 2.

Example 1.

Required torque: 130 Nm / 98 lbf ft.

6 B 20E N SINGLE ACTING ACTUATOR SERIES B1J

OPERATION

The linkage converts linear motion of the piston into a 90° (max. 98°) rotation of the actuator shaft. As a result of the link-age design, the relationship between output torque and piston force depends on the angle of the actuator shaft. The torque output values in the table below show the minimum spring torque (Ms)and the minimum torque (Mp) produced as a result of a specific supply pressure and spring.

ACTUATOR SELECTION

T o select the proper actuator for a par-ticular valve and service, first determine the maximum operating torque that will be required for the valve from the appli-cable valve torque table, then refer to the appropriate mode of operation of the actuator in the torque output tables below and select the actuator that will, at the available air supply pressure, pro-vide a torque output no less than the required operating torque for the valve. If in doubt, select the next larger actuator .

ACTUATOR TORQUE, M n

B1J attachment according to the ISO 5211.

Note: Maximum allowed supply pressure is 120 psi (8.5 bar).B1JK_ has a lighter spring for lower supply pressures.B1J_ for medium supply pressures

B1JV_ has a stronger spring for higher supply pressures.Torque outputs for B1J are identical to those shown for BJ.

GENERAL SELECTIONS GROUNDS

The first selection ground for actuator sizing must always be the torque given by the spring.

Secondly , it must be checked that the available pressure is sufficient to give at least the same torque as the spring, but in the opposite direction.

Note: Max. supply pressure 8.5 bar / 120 psi.Mn =Nominal running torque

M spring =Torque developed by the spring force. Mp =T orque developed by the difference of pressure

force and spring force (eg. M 5 = torque devel-opped with 5 bar). When α = 0° the valve is closed.Example 1.

Required torque:130 Nm / 98 lbf ft.Required action:Spring-to-close.

Nominal spring torque, Ms B1J10 = 150 Nm / 110 lbf ft.Select B1J10.Note:Min. air supply pressure ps = 4.1 bar /

60psi.

Example 2.

Required torque:500 Nm / 370 lbf ft.Required action:Spring-to-open.Step 1.

At the turning angle ? = 90° (valve is fully open), the nominal spring torque B1JA16is 600 Nm / 440 lbf ft.

Step 2.

When air closes the valve (? = 0°) the actu-ator torque (B1JA16) is 650Nm / 480 lbf ft at 4.1 bar / 60 psi supply pressure.Select B1JA16.Note:

At air supply pressures ps < 4.1bar /60psi, contact factory .

气动阀门执行器

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在控制系统中的使用越来越广泛,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和脉冲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。

气动执行机构.doc

阀门气动执行机构的原理及应用(参考学习资料) 二期中工艺系统中采用了大量的气动执行机构阀门,借去苏阀学习的机会向专家们请教了一些关于阀门气动操作机构的知识,在此简单介绍一下。 一.气动执行机构的结构 气动执行机构主要分成两大类:薄膜式与活塞式。 薄膜式与活塞式执行机构均可分成有弹簧和无弹簧的两种。有弹簧的执行结构较之无弹簧的执行机构输出推力小,价格低。而活塞式较之薄膜式输出力大,但价格较高。当前国产的气动执行机构有气动薄膜式(有弹簧)、气动活塞式(无弹簧)及气动长行程活塞式。1.气动薄膜式(有弹簧)执行机构 气动薄膜式(有弹簧)执行机构分为正作用和反作用两种。当气动执行器的输入信号压力(来自调节器或阀门定位器)增大时,推杆向下动作的叫正作用执行机构,如图1所示,我国的型号为ZMA型;反之叫反作用执行机构,如图2所示,我国型号为ZMB型。 这两种类型结构基本相同,均由上膜盖、波纹膜片、下膜盖、推杆、支架、压缩弹簧、弹簧座、调节件、标尺等组成。正作用机构的信号压力时通过输入波纹膜片上方的薄膜气室。而反作用机构则通过波纹膜片下方的薄膜气室,由于输出推杆也从下方引出,因此还多了一个装有“O”型密封环5及填块6。两者之间通过更换个别零件,便能相互改装。 气动薄膜(有弹簧)执行机构的输出信号是直线位移,输出特性是比例式,即输出位移与输入信号成比例关系。动作原理如下:信号压力,通常为0.2-1.0bar或0.4-2bar,通入薄膜气室时,在薄膜上产生一个推力,使推杆部件移动。与此同时,弹簧被压缩,直到弹簧的反作用力与信号压力在薄膜上产生的力平衡。信号压力越大,在薄膜上产生的推力也越大,则与之平衡的弹簧反力也越大,于是弹簧压缩量也越大即推杆的位移量越大,它与输入薄膜气室信号压力成比例。推杆的位移,即为气动薄膜执行机构的直线输入位移,其输出位移的范围为执行机构的行程。 气动薄膜执行机构主要零件结构及作用如下: 1.膜盖:由灰铁铸成(有些小执行机构也有用压制玻璃管代替),与波纹膜片构成薄膜气 室。薄膜气室的容积大小决定执行机构的滞后程度,因此薄膜造型浅些可以减少薄膜气室的容积,加快推杆位移的反应速度。 2.波纹膜片:采用具有较好的耐油及耐高低温性能的丁腈橡胶中间夹以棉纶的支丝织物制 成。其有效面积规格计有200、280、400、630、1000、1600cm2等。波纹膜片有效面积的大小决定执行机构输出推力的大小。在使用各种规格的波纹膜片实际有效面积是随着位移而变化的,且在相同的位移下,有效面积越小,其相对变化越大。如200cm2有效面积变化为9.5%,其余波纹膜片的有效面积变化均不超过6%。 3.压缩弹簧:由65Mn(或60Si2Mn)弹簧钢绕制,并经过热处理。 4.支架:由灰铁铸成(或玻璃钢)。支架正面有两个螺栓孔,用来安装气动阀门定位器。 反面有四个螺栓孔,用来安装操作手轮。 5.调节件:用以调整压缩弹簧的预紧量。 6.标尺:指示执行机构推杆的位移,即反映了调节机构的开度。气动薄膜(有弹簧)执行 机构的行程规格有10、16、25、40、60、100mm等。

气动执行器分类和作用是哪些

气动执行器分类和作用是哪些 常见执行系统主要的分类主要有三种,分别是气动、电动以及液动,在这三种执行器中它们都具备着不同的特点,同时在运用上也不相同,在运用场合上也不相同。气动执行器属于三大执行器中的一种,而在气动执行器中它还有着分类,下面对它的主要的分类做一个简单的介绍: 气动执行器在分类上主要有两种,一种为双作用执行机构,一种为单作用的执行机构,这两种执行机构存在着什么区别,在什么情况下才能选用呢? 双作用的气动执行机构 双作用的气动执行机构主要就是在它的组成上一齿轮条式执行机构来输出力矩的,它的主要来源就是活塞装置上产生的压力呈现出节圆半径所得的,在工作中它的摩擦的阻力比较小,但是它的效率是非常高的。在双作用执行机构进行工作时,不管是它的顺时针还是逆时针的输出力矩都是线性的。在一般的正常的操作下,双作用的执行机构的推荐安全系数为百分之二十五到百分之五十。 单作用的执行机构的选用 单作用的执行机构的选用主要就是在弹簧复位的应用中,它的力矩的输出主要就是在两个不同的操作中所得到的,根据它工作的行程的位置,在每一次的操作中都会产生两个不相同的力矩值。在弹簧复位机构的输出力矩上,主要是由空气的压力以及弹簧的作用力从而产生第一种情况,输出的力矩主要是由空气中的压力在进入了中腔压缩弹簧之后得到的,这样也迫使了活塞的位置发生一定的变化。 在弹簧的压缩中产生的反作用力,它的力矩从起点开始形成的最大值逐渐的递减这是第二种情况的出现。它输出的力矩主要就是当中腔在失气时弹簧的恢复力作用在活塞上所得的,由于弹簧在不断的伸长,输出力矩也会发生一定的变化。 气动执行器的双作用以及单作用执行机构的选用还要根据实际的工作情况来做决定,而选择了真正适用于工作环境的执行机构这样对工作来说就起着重要的有利作用,相反,则会影响了工作。 文章来源:气动蝶阀: https://www.doczj.com/doc/f47825773.html,/

气动执行器结构及原理

气动执行器结构及原理 The final edition was revised on December 14th, 2020.

气缸结构与原理学习 气动执行机构 气动执行机构俗称又称气动执行器(英文:Pneumatic actuator ) 按其能源形式分为气动,电动和液动三大类,它们各有特点,适用于不同的场合。气动执行器是执行器中的一种类别。 气动执行器还可以分为单作用和双作用两种类型:执行器的开关动作都通过气源来驱动执行,叫做DOUBLE ACTING (双作用)。SPRING RETURN (单作用)的开关动作只有开动作是气源驱动,而关动作是弹簧复位。 气动执行机构简介 气动执行器的执行机构和调节机构是统一的整体,其执行机构有薄膜式、活塞式、拨叉式和齿轮齿条式。活塞式行程长,适用于要求有较大推力的场合;而薄膜式行程较小,只能直接带动阀杆。拨叉式气动执行器具有扭矩大、空间小、扭矩曲线更符合阀门的扭矩曲线等特点,但是不很美观;常用在大扭矩的阀门上。齿轮齿条式气动执行机构有结构简单,动作平稳可靠,并且安全防爆等优点,在发电厂、化工,炼油等对安全要求较高的生产过程中有广泛的应用。 齿轮齿条式:

齿轮齿条: 活塞式: 气动执行机构的缺点 控制精度较低,双作用的气动执行器,断气源后不能回到预设位置。单作用的气动执行器,断气源后可以依靠弹簧回到预设位置 工作原理说明班 当压缩空气从A管咀进入时,气体推动双活塞向两端(缸盖端)直线运动,活塞上的齿条带动旋转轴上的齿轮逆时针方向转动90度,阀门即被打开。此时气动执行阀两端的气体随B管咀排出。反之,当压缩空气从B官咀进入气动执行器的两端时,气体推动双塞向中间直线运动,活塞上的齿条带动旋转轴上的齿轮顺时针方向转动90度,阀门即被关闭。此时气动执行器中间的气体随A管咀排出。以上为标准型的传动原理。根据用户需求,气动执行器可装置成与标准型相反的传动原理,即选准轴顺时针方向转动为开启阀门,逆时针方向转动为关闭阀门。单作用(弹簧复位型)气动执行器A管咀为进气口,B管咀为排气孔(B管咀应安装消声器)。A管咀进气为开启阀门,断气时靠弹簧力关闭阀门。

气动阀门执行器的控制方式及工作原理

气动阀门执行器的控制方式及工作原理 气动执行器结构 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)基于单片机开发的智能显示仪控制 智能显示仪是用来监测阀门工作状态,并控制阀门执行期工作的仪器,它通过两路位置传感器监视阀门的工作状态,判断阀门是处于开阀还是关阀状态,通过编程记录阀门开关的数字,并且有两路与阀门开度对应的4~20mA输出及两足常开常闭输出触点。通过这些输出信号,控制阀门的开关动作。根据系统的要求,可将智能阀门显示仪从硬件上分为3部分来设计:模拟部分、数字部分、按键/显示部分。 1、模拟电路部分主要包括电源、模拟量输入电路、模拟量输出电路三部分。 电源部分供给整个电路能量,包括模拟电路、数字电路和显示的能源供应。为了实现阀门开读的远程控制,需要将阀门的开度信息传送给其他的控制仪表,同时控制仪表能从远方制定阀门为某一开度,系统需要1路4~20mA的模拟量输入信号和1~2路4~20mA的模拟量输出信号。模拟量输入信号通过A/D转换变成与阀门开度相对应的数字信号后送给数字部分的单片机,在单片机中对它进行滤波处理后就可以输出了。阀门的开度信息通过D/A转换后变成模拟信号输出,用来接显示仪显示阀门开度或连接其他的控制设备。在本设计系统中,所有的数字量数据均采用串行的输入输出方式,为了节省芯片资源和空间,输入的4~20mA 的模拟量在转化为数字量时,采用已有的4路DA芯片与单片机的系统资源相结合作8位的AD使用。

2、数字电路部分主要包括:单片机、掉电保护、两路监测脉冲输入信号、两路常开常闭转换触点输出。 在设计方案中选用目前普遍使用的51系列单片机AT89C4051。AT89C4051是一款低电压、高性能的CMOS8位微控制器,它具有4K字节的可擦除、可重复编程的只读闪存。通过在单芯片内复合一个多功能的8位CPU闪存,在性能、指令设定和引脚上与80C51和80C52完全兼容。 考虑到在系统掉电或重新启动时,需要保持先前在仪表中设置的一些阀门参数,而单片机中的数据存储器不具备掉电存储功能,所以在片外扩展了一个具有掉电保存功能的芯片X5045。X5045是一种集看门狗、电源监控和串行EEPROM3种功能于一身的可编程电路,这种组合设计可以减少电路对电路板空间的需求,X5045中的看门狗为系统提供了保护,当系统发送故障而超过设定时间时,电路中的看门狗将通过RESET信号向CPU作反应。X5045提供了三个时间值供用户选择使用。它所具有的电压监控功能还可以保护系统免受低电压的影响,当电源电压降到允许范围以下时,系统将复位,直到电源电压返回到稳定值为止。X5045的存储器与CPU可通过串行通信方式接口。共4069位,可以按512×8个字节来放置数据。 X5045的管脚排列,它共有8个引脚,各个引脚的功能如下: CS:电路选择端,低电平有效; SO:串行数据输出端; SI:串行数据输入端; SCK:串行时钟输出端; WP:写保护输入端,低电平有效; RESET:复位输出端; Vcc:电源端; Vss:接地端。 INA为输入信号,是由光电传感器采集到的阀门脉冲信号(<10mA)。该信号经旁路电容滤波后送入光耦,转换成了输出的OUT电压信号送入单片机。输出的电压可直接进入单片机的I/O口。在控制中,要求A、B两路脉冲都接收到的时候,才认为是由信号输入,AB为正转,BA为反转。只有一路信号输入时不计数。 两路常开、常闭转换触点输出。用来连接电磁阀,通过控制电磁阀的吸合来控制气动执行机构作相应的开阀或关阀动作。 3、显示部分主要包括:单片机、4位LED显示、3只状态指示灯(自动、正转、反转)、3
