SMC速度控制阀AS系列产品介绍
SMC速度控制阀AS系列产品介绍SMC速度控制阀AS系列作用SMC 速度控制阀AS系列是由单向阀和节流阀并联而成的流量控制阀，常用于控制气缸的运动速度，故称为速度控制阀。
下图为速度控制阀在回路中的两种连接方式，左边的回路为排气节流方式，换向阀通电后，气缸进气侧的单向阀开启，向气缸无杆腔快速充气，有杆腔的气体只能经排气侧的节流阀排气。
调节节流阀的开度，便可改变气缸的运动速度。
这种控制方式，活塞运行稳定，是最常用的回路。
而右侧的回路则为进气节流方式，进气侧单向阀关闭，排气侧单向阀开启。
进气流量小，进气腔压力上升缓慢，排气迅速，排气腔压力很低。
主要靠压缩空气的膨胀使活塞前进，故这种节流方式很难控制气缸的速度达到稳定。
一般只用于单作用气缸、夹紧缸和低摩擦力气缸的速度控制。
SMC AS系列速度控制阀结构原理下图分别是SMC AS系列排气节流、进气节流速度控制阀以及万向型和大流量直通型调速阀的结构原理图。
SMC AS系列速度控制阀系列和分类SMC 速度控制阀的种类繁多。
按安装方式，有直接安装型（接头体靠螺纹连接在气缸通口上，另一端为快换接头或配管）和面板安装型（将调速阀固定在面板上，气路连接为快换接头）。
按气体流动方向，有直通式（进出口在一条线上）、弯头式（进出口方向成90°）和万向型（出口方向可绕进口方向转动）。
按阀体材质分，有金属阀体和树脂阀体。
按功能分，有标准型，带残压释放阀的形式（AS□FE系列）不锈钢阀体形式（AS□FG系列，可用于耐腐蚀的环境中）、低俗控制用的形式（AS□FM系列、10~50mm/s)/洁净环境用的形式（AS□FPG、AS□FPQ系列，用于洁净室）、用选举调节的形式（AS□1F-□D系列）、用专用工具调节的形式（AS□1F-□T系列）。
此外还有双向型速度控制阀ASD系列。
带先导式单向阀的速度控制阀ASP系列。
SMC AS系列速度控制阀主要技术参数参见SMC样本。
SMC AS系列速度控制阀的选用根据速度控制的气缸缸径和对气缸速度变化范围的要求，计算控制流量的范围，然后从产品样本上查节流特性曲线，选择速度控制阀范围的规格。
AS-I总线教程
对于普通I/O设备来说，如果想接入AS-I系统，必须提供一个带有ASIC的AS-I模块，I/O设备与这些模块连接。
·供电电源
供电电源为30VDC，必须使用专用的AS-I电源，并且直接与数据线连接。AS-I从站正常工作的电压至少在26.5V以上。一个从站消耗的电流在100mA以上，一个分支上的所有从站消耗电流大约为2A，AS-I电缆能提供的最大容量为8A。当消耗的电流过大时，需要添加辅助电源。辅助电源为24VDC，用一个双芯黑色无屏蔽的电缆将辅助电源与从站连接起来。辅助电源线同样使用穿刺技术连接。
·具有坚固的网络拓扑，不需要屏蔽和终端电阻，即使在恶劣环境中也能保证通信的可靠性。
·网络中只有１个主站，最多31个从站，每个从站有４位I/O可以利用。
·最多124个I/O传感器和执行器。
·主从站间采用循环方式进行访问。
·循环时间最大5ms。
·网络连接电缆为双芯、非屏蔽、1.5mm²的黄色异型电缆或圆形电缆。最大长度为100m。使用中继器可扩展到300m。但最多只能使用两个中继器。
每个等级的网络都与上下相邻的网络连接，可以判定相互间通讯的需求。在最上层网络，存在众多复杂的计算机系统，能够不定期的对各种复杂数据进行响应，大量的通讯参与者和响应者在网络中相互协调。
在最底层，依然有很大的信息吞吐量，只是数据相对要少于上层结构。
在自动化系统网络中可以分为以下5层结构：
·计划编制层（Planning Level），对来自生产层的信息进行评价，组织编排并协助生产部门进行决策。在这一层中，不论是信息量还是传输速率和距离都是最大的。
AS-I主站采用轮询方式访问，即按照顺序一个一个的对从站进行访问。这个顺序就是在上电时，主站第一次访问时建立的地址列表。如果在访问时，从站在规定时间内没有对主站的请求作出响应，主站会立即重复访问一次。还没有响应的话，主站将访问下一地址。在后面的两个周期内，主站会继续尝试访问先前丢失的地址，如果依然没有回应，故障错误位会被置位，并将该信息发送给PLC。

ASI信息结构
主站请求和从站应答
在ASI主从结构中，主站所发出的报文在系统数据交换中占有重要的 地位。主站的请求报文共有9种：（1）数据交换 要求从站把测量数 据上传给主站，而主站又可以把控制指令下达给从站。（2）写参数 设置从站功能，如传感器的测量范围、激活定时器、在多传感器系统 中改变测量方法等。（3）地址分配 只有当从站地址为00H时才有效。 从站接到这个请求后，用06H回答，表示已收到了主站的正确请求， 从站从此就可以在这个新地址被呼叫了，同时把这个新地址存储在从 站的EEPROM中，这个过程大约需要15ms。这种方式使主站可以对 运行中损坏后重新置换的从站自动进行原有地址的设置。（4）复位 把被呼叫的从站地址恢复到初始状态，从站用06H回答，整个过程需 2ms。（5）删除操作地址 暂时把被呼叫的从站地址改为00H，这个 报文一般和“地址分配”报文一起使用。当新地址确定后，从站用 06H回答。如果使用指令“Reset-ASI-Slave”就可以恢复原地址。 （6）读I/O配置。（7）读ID编码 从站的I/O设置和ID编码在出厂时 已经确定，不能改变。（6）、（7）结合使用的目的是确定从站的身 份。（8）状态读取 读取从站状态缓冲器中的4个数据位，以获得在 寻址和复位过程中出现的错误信息。（9）读出状态和状态删除 读出 从站状态缓冲器的内容，然后删除。

as系列基础知识问答讲解
基础知识篇Q: 什么是执行器？A: 顾名思义，就是用来执行命令的一种执行装置。
工业生产过程自动调节系统一般由检测器、调节器、执行器和调节对象组成。
其中执行器总是不可缺少，执行器在自动控制系统中的作用相当于人的四肢，它接受调节器的控制信号，改变操纵变量，使生产过程按预定要求正常执行。
一般由执行机构和调节机构（一般称为调节阀）组成。
此外，根据需要还可配上阀门定位器和手轮机构等附件。
Q: 执行机构和调节机构的作用是什么？A: 执行机构是指根据调节器控制信号产生推力或位移的装置，而调节机构是根据执行机构输出信号去改变能量或物料输送量的装置，而调节机构是根据执行机构输出信号只改变能量或物料输送量的装置，最常见的是调节阀。
Q: 现在主流的执行器分类有哪些？A: 执行器按其能源形式分为液动、气动和电动三大类，它们各有特点，适于不同的场合。
随着近几年来科学技术的不断发展各类执行机构正逐步走向智能化的道路，而其中专门和气动执行器配套使用的智能阀门定位器和全电子电动执行器的出现更加速了执行机构智能化的发展，为执行器的应用开辟了新天地。
Q: 液动执行器的特点是什么？A: 液动执行器推力最大，一般都是机电一体化的，但比较笨重，所以现在使用不多。
但也因为其推力大的特点，在一些大型场所因无法取代而被采用，如三峡的船阀用的就是液动执行器。
Q: 气动执行器的特点是什么？A: 气动执行器的执地机构和调节机构是统一的整体，其执行机构有薄膜式和活塞式两类。
活塞式行程长，适用于要求有较大推力的场合，不但可以直接带动阀轩，而且可以和蜗轮蜗杆等配合使用；而薄膜式行程较小，只能直接带动阀杆。
其执行器分为正作用和反作用两种形式，所谓正作用就是信号压力增大，推杆向下；反作用形式就是信号压力增大，推杆向上。
这种执行机构的输出位移与输入气压信号成正比例关系，信号压力越大，推杆的位移量也越大。
当压力与弹簧的反作用力平衡时，推杆稳定在某一位置，气动执行器又有角行程气动执行器和直行程气动执行器两种。

访问方式和报文
ASI总线系统为主从结构，采用请求-应答的访问方式。 主站先发出一个请求信号，信号中包括从站的地址。接 到请求的从站会在规定的时间内给予应答，在任何时间 只有1个主站和最多31个从站进行通信。一般访问方式 有两种：一种是带有令牌传递的多主机访问方式；另一 种是CSMA/CD方式，它带有优先级选择和帧传输过程。 而ASI的访问方式比较简单，为了降低从站的费用、提 高灵活性，一方面在不增加传输周期的条件下尽量包括 更多的参数和信息，另一方面传输周期的时间应能自动 调整，例如系统中只有6个从站时，传输周期为1ms， 而有31个从站时周期约为5ms。如果在网上有短暂的 干扰时，主站没有收到从站的应答信号或收到的是错误 无效的信号时，主站可以重发信息而无需重复整个传输 周期。
数据解耦电路
数据解耦电路由两个50μH的电感和两个 39Ω的电阻相互并联组成，通过电感可以将 传输信号的电流脉冲转变为电压脉冲，同时 它还有防止数据传输频率信号经过电源而造 成短路的作用，两个电阻代表了网络边界终 端。为使电路信号噪声最低，必须采用高对 称性的电路结构，两个电容CE和两个电感L 应完全相等，接地电要可靠接地，若采用屏 蔽电缆，屏蔽层也应接到地上。

AUMA执行器1
AUMA执行器1．AUMA执行器产品介绍AUMA执行器不论是其控制部分还是减速机构，最显著的特点就是它的模块化设计，使其具有高度的配置和使用的灵活性。
AUMA电动执行器包括多转式（multi-turn）、部分转角式（part-turn）和直行程（linear）三种。
其中多转式的力矩范围为10---32000NM，部分转角式力矩范围25---360000NM，直行程的推力为3.8---217KN。
AUMA多转式执行器SA系列主要应用于开关插板门以及球阀；部分转角式主要分为AS系列和SG系列，其转角0—90度行程时间为4---180秒，主要应用于蝶阀控制；直行程执行器实际上是由多转式执行器（SA）与线性减速机构（LE）组合而成，它主要是通过推拉实现对阀门的控制。
2．在用的AUMA执行器2．1 直行程：直行程执行器（亦称为直推直拉式）主要应用于automate globe vavle、butterfly vavle、modulating vavle的控制。
2．1．1 普通AUMA执行器：无论是何种型号的AUMA执行器，它的基本操作模式都有两种，即本机操作模式（LOCAL）和远程控制模式（RAMOTE）；其中远程控制模式还包括远程开关量控制和远程模拟量控制两种方式。
在本机控制模式下，执行器可以通过按钮进行操作，方便检修。
普通AUMA执行器的就地调整主要包括行程、力矩开关的调整和零满调整。
1）行程限位开关的调整：首先要用手轮将执行器操作到全关位置，也可用力矩关到底然后回调若干定为全关行程限位位置（此位置须由阀门厂家或或管阀班人员确认），然后压下调试轴A，并以箭头所示方向旋转，可以感觉和听到驱动轴齿轮啮合转动的咯哒声，同时指针B以90度的步进速度旋转，当指针B刚好指向红点C时，停止转动A，则限位定好。
（如果指针B调过红点C或是A轴旋转过头，不要反向调整，继续按箭头所示方向进行调整，重新进行限位）。

For category C5-M, an epoxy resin coating is recommended.Application, Characteristics, Technical DataDesign and function of the gas pressure regulator (GPR)The gas pressure regulators RSP 254/255 have the function of keeping the outlet pressure of a gas train downstream of a gas pressure regulator largely constant within specified limits, independently of changes in the gas tap or inlet pressure. The required auxiliary energy is obtained from the pressure gradient between the inlet pressure and outlet pressure of the gas pressure regulator. No external energy is required, and no gas whatsoever will flow out of the system into the surrounding atmosphere in standard operation. The regulator consists of the regulating unit, optionally connected upstream to a micro filter and bypass valve.The control variable - the outlet pressure - is detected by a sensitive diaphragm in the regulating unit, which is part of a double-diaphragm system. The pneumatic amplifier working by the nozzle/baffle plate principle is actuated by the comparator formed by a double-diaphragm system. The bypass valve and possible changes in the setpoint spring can be used to affect the static amplification of the regulator and adjust it to the respective condition of a gas train.The outlet pressure is applied to the top side of the double-diaphragm system in the regulating unit via a measurement line, converted into a pressure force and compared with the set setpoint spring force as command variable. Any deviation from the control value is followed by a suitable proportional change in the spacing between nozzle and baffle plate, corresponding to a proportional change in the setting pressure. The valve opening required in each case for adjusting the outlet pressure actual value to the setpoint is effected by the setting pressure generated by the actuating drive of the actuator.In the operating state, the inlet pressure taken at the inlet flows as auxiliary energy through the nozzle/baffle plate system and the bypass valve into the outlet pressure chamber, generating, depending on the position of the nozzle/baffle plate system, the setting pressure for the valve opening position required in each case against the bypass valve. The auxiliary energy gas then flows back to the outlet pressure network via the bypass valve.In case of zero tap of the gas train, the amplifier valve in the double-diaphragm system of the regulating unit will close tight, causing the closing pressure to be established.Models with pneumatic follow-up setpoint inputs with 1:1 and 1:2 pressure conversions are available. Using, for example, IP converters allows you to continuously set directly the required outlet pressure setpoint via, for example, 4 to 20 mA signals.Moreover, by means of a setting spring, variable zero points can be suppressed.Design and function of the safety shut-off valve (SSV) direct-actingIn case of inadmissible overpressure or lack of gas in the gas train, the actuator of the safety shut-off valve arranged in the same housing on the inlet side will shut off the gas flow.To this end, the outlet pressure to be monitored is passed on to the SSV control device via a separate measurement line. As a function of the change in pressure, the SSV diaphragm in the control device is raised or lowered. When the outlet pressure in the gas train exceeds or falls below a certain response pressure, the switch socket connected to the SSV diaphragm will move to the corresponding disengaging position, the balls of the engaging mechanism will release the SSV screw spindle, and the closing spring will press the SSV valve plate against the valve seat. The SSV actuator shuts off the gas flow gas-tight. The SSV can only be opened by hand and engaged in the open position. To do so, the outlet pressure at the measuring point must be lowered below the upper response pressure or raised above the lower response pressure by at least the re-engaging differential amount (Δp). The SSV can, except where otherwise stipulated in national legislation, be used either in function class A (with diaphragm rupture protection) or B (without diaphragm rupture protection).There is also the option of using a remote display for the SSV position 'CLOSED' and a manual and remote release when power is applied or in case of power failure.Design and function of the safety shut-off valve (SSV) indirect-actingAt a safeguarding pressure of the gas train of greater than 4 bar, the SSV must be combined with a control device K70-10. In this case, the SSV switching device is designed as function class B and set to a switching pressure of approx. 500 mbar. The control device K70-10 connected upstream of the switching device is set to the upper safeguarding pressure. As soon as the pressure of the gas train reaches the upper safeguarding pressure, the control device will open and allow the gas pressure to flow to the measurement connection of the SSV switching device. Here a pressure of more than 500 mbar will build up, causing the switching device to release as described above. The excess pressure in the measurement line will be let down by flowing into the breather line via the bypass throttle and safely released into the atmosphere.Setting deviceSSVActuator housingSSV connection optionsBV breather valve Sectional viewActuator AS 255• Wdsoup to4 bar with controldevice MD or MD-R• Wdsofrom 4 bar with controldevice K 70-10 (indirect-acting)Option: Noise reductioncontrol deviceInlet pressureSetting pressureOutlet pressureAtmosphereNoise reductionFF micro filter for R70FF micro filterSectional viewRegulators R 70-10, R 70-20, R 70-100 and SSV control device K 70-10R 70-10R 70-20R 70-100Double-diaphragm systemDouble-diaphragm systemSetpoint spring 100 cm 2Measuring movementSetpoint springBypass setting deviceR 70-20with pneumatic 1:2 pressure converter for follow-up setpoint adjustment, for example, via I/P converterBypass setting device 20 cm 2Measuring movementDouble-diaphragm systemSetpoint spring Double-diaphragm system10 cm 2Measuring movementI/P converter Pressure converter20 cm²K 70-10SSV control deviceSetpoint setting deviceSetpoint setting deviceSetpoint setting deviceBypass setting deviceApplication, Characteristics, Technical DataK G * valueAccuracy class AC / Closing pressure group SG*) KG value for natural gas: d = 0.64 (ρn = 0.83 kg/m³), t ugas = 15 °C **)Optionally, the control device K70-10 can be used as SBV.(Δp u,max ± 2bar )Setting device is approved for a max. pressure differential of 0.5 barUpper response pressure group AG30 mbar to 100 mbar AG 10100 mbar to 500 mbar AG 5> 500mbar AG 2.5Lower response pressure AG5 mbar to 30 mbar AG 2030 mbar to 50 mbar AG 10> 50mbar AG 5Response pressure group AG (SSV direct-acting)Upper response pressure group AG800 mbar to 4,000 mbar AG 2.5> 4,000 mbar AG 2,5Response pressure group AG(SSV indirect-acting) control device K 70-10**Determining the upper response pressureOutput pressure P dUpper response pressure W dso *≤200 mbarP d +100 mbar >200 mbar to ≤800 mbar P d x 1.5>800 mbar to ≤1600 mbarP d x 1.3> 1600mbarP d +500 mbarP h Pneumatic follow-up setpoint from I/P converter (0-6 bar)P d100 Outlet pressure R70-100 P d20 Outlet pressure R70-20 P d 20s Outlet pressure R70-10 with follow-up setpoint 1:2P d10 Outlet pressure R70-10 P d 10s Outlet pressure R70-10 with follow-up setpoint 1:1P dOutlet pressure K70-10*) The upper response pressure is rounded up to full tens, for example 251 mbar-> 260 mbarRegulator setpoint spring tableDimensions, Connection and WeightAS 254: Connection of the functional line and breather lineNominal widthSetting deviceSSV control device direct-actingSetting pressure line / Return lineSSV measurement lineBreather lineDN 025Connection* for: Tube 12 x 1.5 (thread G 3/8)Connection* for: tube 12 x 1.5 (thread G 1/4)DN 050DN 080DN 100DN 150Connection* for: tube 12 x 1.5 (thread G 3/8)DN 200AS 255: Connection of the functional line and breather linesNominal widthSetting deviceSSV control device direct-actingSetting pressure line / Return lineSSV measurement lineBreather lineDN 050Connection* for: Tube 12 x 1.5 (thread G 3/8)Connection* for: tube 12 x 1.5 (thread G 1/4)DN 080DN 100Connection* for: tube 12 x 1.5 (thread G 3/8)*) Threaded pipe connections to DIN EN ISO 8434-1 (DIN 2353)Note: Observe the following documents in relation to installation, start-up and maintenance:DVGW - work sheets G 491 and G 600Operating and Maintenance Instructions RSP 254 / 255The gas pressure regulators RSP 254 / 255 shall be installed in the pipeline preferably in horizontal position.

AS全智能化电动阀门执行器技术特点
1、电气要求
1)电动阀门执行器的电源为额定电压220V或380V、单相或三相交流电、额定频率
50Hz。
2)执行器工作的环境温度为-30︒C~+70︒C，并能耐受强电磁干扰。
3)电动阀门执行器或其减速装置的最大输出扭矩不低于对应阀门需要的最大开启和关
闭力矩，并至少有20%的富裕量。
4)执行器具有自动识别三相电源相序的功能，即无论三相电源接线顺序如何，如果接
收到“开”命令，执行器总是按“开方向”运行，如果接收到“关”命令，执行器总是按“关方向”运行，用户接线就非常方便，不会造成接线错误导致损坏执行器和阀门。
5)电动阀门执行器具备“电动/手动”切换机构，当切换到手动操作时，放开切换杆，
切换杆应能自动弹回原始位置，这时，如果执行器电动机转动，执行器能够自动置于电动操作状态。
6)用于开关型的执行器的最大启动频率不小于60次/小时，用于调节型的执行器的最
大启动频率不小于900次/小时。
2、控制功能
1)对阀门的阀位和扭矩的检测和控制是采用电子方式，不同于普通电动执行器采用的
行程开关等纯机械式检测和控制方式。
这样，有效保证了对阀门的阀位和扭矩参数进行稳定、精确的测量，有效的保证了用户使用的可靠性。
电动执行器对阀门阀位的检测精度< 0.2%，对阀门扭矩的检测精度< 5% 。
2)执行器带有全中文菜单的运行和设置液晶显示界面，用户可通过红外线设定器对执
行器的参数在现场根据需要进行设置，操作非常简单和便捷。
3)电动阀门执行器能够将当前的输出扭矩和阀位通过自带的液晶显示屏实时显示出
来，操作人员在现场就可方便监控。
当阀位到达预定位置或输出扭矩超过预先设定的值，执行器能够自动停转，并进入待命状态。
4)阀门的全开和全关位置，以及最大保护扭矩，能够在现场通过红外线设定器由用户
自行设置，执行器能够存储这些设置，并按这些设置来运行。
5)执行器具有故障保护功能，包括电源缺相保护、电机过热保护、阀门卡塞保护、瞬
时逆转保护、电机过流保护等，出现这些故障后，执行器能够自动发出报警，并能自动停转。
6)执行器支持总线控制方式，支持Modbus RTU或Profibus DP等通用协议，也支持多
线控制方式。
(由用户要求配置，标准配置中不含总线控制功能板卡)
7)执行器的输出扭矩值和阀位值能够通过4-20mA信号输出，以便中央控制系统采集
和处理。
用于调节型的执行器能够接收4-20mA控制信号，按该信号实时控制阀位。
(由用户要求配置，标准配置中不含模拟量控制功能板卡)
8)电动执行机构在失去动力电源时，应能保持在失电前的原位保持不动，在失去控制
信号时，可根据用户设定选择开、关、停在原位不同的应急措施。
3、密封和防护
1)执行器的防护等级应达到IP68。
能适应于各种潮湿、多尘现场恶劣环境。
2)执行器的现场接线端子采用双密封结构，在打开端子室盖接线时，周围的潮湿型气
体、粉尘、爆炸型气体不会侵入到执行器内部，有效保障执行器的可靠运行。
3)执行器现场操作旋钮或按钮的轴采用非贯穿执行器外壳方式，以免影响防水。
4)执行器应采用液态油润滑，无论何种安装方位，均不出现润滑油渗漏的现象。
4、质量保证
执行器的保质期为1年，在保质期内由于非人为因素造成的故障，均由厂家免费维护。
