多级阀的工作原理
主阀芯的位置闭环控制是由集成电子装置来实现的。 一个电气指 令信号 （ 用来设定流量 ） 作用于集成电路位置控制器并由此来驱 动阀线圈。 位置传感器通过振荡器测出主阀芯的实际位移 （实际 值， 位移电压） 。 此信号被解调并反馈至控制器与指令信号相比较。控制器驱动先 导阀偏转从而使主阀芯产生位移，直至指令信号与反馈信号之间 的偏差为零。由此得到主滑阀的位移与指令电信号成正比。
阀的体积流量计算
阀的实际体积流量取决于阀芯位移和阀口两端节流边的压降。 在 100% 指令信号（即 +10 V DC = 100% 阀口全开）、额定压降 ∆pN = 每节流边 5 bar (75 psi) 时，阀的体积流量定义为额定流量 QN。对于非额定压降，在一个特定的指令信号下，阀的体积流量 则与阀的锐边节流口的压降的平方根成正比。 Q [l/min] = 计算出的流量 = 阀的实际压降 = 阀的额定压降

INTRODUCTIONThis manual provides instructions and procedures necessaryto install, operate and troubleshoot the Moog D661 Series Servo and Propor-tional Control Valves.2. OPERATIONGeneralThe Servovalves D661-G, S and H Series and the Proportional Flow Control Valves D661-P Series are throttle valves for 2-, 3- and 4-wayapplications. With proportional flow control valves, 5-way applications are also possible. These valves are suitable for electrohydraulic position, velocitiy,pressure or force control systems with high dynamic response requirements.D661-G, S and HThe spool of the main stage is driven by a nozzle flapper or ServoJet ®pilot stage, optional with or without additional mechanical feedback (nozzle flapper only).With versions D661-S and H in case of an electrical supply failurethe spool is moved into a preferred position by action of an additional mechanical feedback.E LE CTROHYDRAULIC VALVE CUT -AWAYFigure 1 Moog Series D661-G Series, without additional mechanical feedbackX T A P BT 2YConnectorSpoolBushingScrew Plug for Null AdjustSeries Models Series GServovalve with nozzle-flapper or ServoJet ® pilot stage, spool in bushing, without additional mechanical feedbackSeries S Servovalve configured like version G, but with additional mechanical feedbackSeries H Servovalve configured like version S, but with improved performance (high response)Series P ...A/B Proportional valve with ServoJet ® pilot stage, spool in body ,without additional mechanical feedbackSeries P ...F/GProportional valve configured like version P ...A/B, but with nozzle flapper pilot stage and additional mechanical feedbackJet pipe Annular areaNozzleReceiver2Operating Principle of the T wo-Stage ValveAn electric input signal (flow rate command) is applied to the integrated control amplifier which drives a current through the coils of the pilot stage torque motor. Thus the deflected nozzle-flapper system produces a pressure difference across the drive areas of the spool and effects its movement. The position transducer which is excited via an oscillator measures the position of the spool (actual value, position voltage).This signal is then rectified by a demodulator and is fed back to the control amplifier where it is compared with the command signal. The control amplifier drives the torque motor until command voltage and feedback voltage are equal.Thus, the position of the spool is proportional to the electric command signal.Proportional Flow Control Valve D661-...PThe nozzle flapper design of the pilot stage has been converted into an improved version with jet pipe amplifier (ServoJet ®).The ServoJet ® pilot stage consists mainly of torque motor, jet pipe and receiver.A current through the coil displaces the jet pipe from neutral. This displacement combined with the special shape of the nozzle directs a focussed fluid jet more into one receiver bore than into the other.The jet now produces a pressure difference in the control ports. This pressure difference results in a pilot flow, which in turn causes a spool displacement. The pilot stage drain is through the annular area around the nozzle to tank.Operating Principle of the T wo-Stage ValveAn electric input signal (flow rate command) is applied to the integrated control amplifier which drives a current through the coil of the pilot stage torque motor. The thus deflected jet pipe produces a pressure difference across the drive areas of the spool and effects its movement.The position transducer which is excited via an oscillator measures the position of the spool (actual value, position voltage). This signal is then demodulated and fed back to the controller where it is compared with the command signal. The controller drives the torque motor until the error between command signal and feedback signal is zero. Thus the position of the spool is proportional to the electric command signal.Failsafe Version D661-...PFor applications with proportional control valves where certain safety regulations are applicable, a defined metering spool position is needed in order to avoid potential damage. Therefore, failsafe versions are offered as an option for the MOOG proportional valves.After external triggering, this failsafe function causes a defined metering spool position.Mechanical Failsafe version (biased pilot stage with mechanical feedback)The safe position of the spool will be obtained after cut off of pilot pressure supply (external pilot connection) or operating pressure supply D661-P ...A/BWD661-P ...A/BU Proportional Valve D661-P ...A/BWand D661-P ...A/BU Series with electrically operated failsafe functionProportional Valve D661-P ...AP Serieswith electrically operated failsafe function2- stage Proportional Valve D661-...P ...A/B SeriesServovalve D661 - ...S and H Series with additional mechanical feedback3Electric characteristics of the 2/2-way solenoid valveFunctionelectro magnetic Nominal voltage 24 VDC Nominal power12 WDIN 43650-1Form A: 2+PE-PG9With failsafe versions R and L, a defined spool position is reached when the electric supply to the valve electronics is switched offwhile the pilot pressure is still applied. With version M, the resulting spool position is undefined.Electrically operated failsafe versionThe safe position of the spool will be obtained after switching off the integrated 2/2-way solenoid seat valve.With failsafe versions W , U and G, after cut-off of the solenoid, the spool moves to midposition. When the electric supply to the valveelectronics is switched off while the pilot pressure is still effective and the solenoid is still switched on, the spool will move to a defined end position with versions U and G.With failsafe version P , the integrated seat valve will shut off the external pilot pressure after switching off the solenoid.Cutting off the 24 VDC supply to the solenoid operated 2/2-way seat valveo protect relay contacts or semiconductors against damage, a Zener diode is required1)With version P at 210 bar pilot or operating pressure,with versions G ,S and H at 140 bar pilot or operating pressure,fluid viscosity of 32 mm˝/s and fluid temperature of 40°C.2)For long life wear protection of metering landsFor additional technical information such as dimensions, ordering information, etc., see the D660 series catalog.T echnical DataInternal/External Pilot Connection a.Conversion for operation with internal or external pilot connection.The pilot connection mode as shipped is indicated by the respective code letter of the type designation on the nameplate.With the 5-way version, where the T and T 2 ports are interchangedwith the P port, pilot supply port X and return portY must be connected externally.43.

The P- and T-connections are flushed through the flushing plate. The user A- and B-Attention: The directional valve can lead to unpermissablemovements in the load (i.e. with parallel drives), which may result in damage of the plant / machine. Instructions of the manufacturer have to be strictly observed.Minimum flushing time t can be calculated as follows:d.The flushing process can be considered completed when a system cleanliness of 15/12 according to ISO 4406 or 6 according to NAS1638 or better is achieved. A long life of the metering lands of the proportional valve can be expected for this cleanliness class.V = content of reservoir [gallons]Q = flow rate of the pump [gpm]t = V • 5Qe.Replace flushing elements in the pressure filters by suitable high pressure elements after flushing. Install Moog proportional valve instead of flushing plate or directional valve.Setting Up a.Set up machine/plant according to the operation instructions of the manufacturer after the valves have been installed. Vent hydraulic system!b.The safety instructions of the machine/plant manufacturer must be observed. Especially the safety requirements for machines like injection molding machines (EN 201), blow molding machines (EN 422) and die casting machines (EN 869), to name a few, are important.c.Observe oil temperature.d.Check hydraulic system for external leakage!6. MAINTENANCEBesides regular visual inspection for external leakage and filter replacement, maintenance work at the D661 Series valves is not required.Explosion proof valves D661K... must not be opened by the customer! Unauthorized opening will invalidate the explosion proof approval! Return failed valve to the factory.Moog valves can only be repaired at Moog Service Centers (for addresses see back page of this operation instructions).Filter ReplacementThe built-in filter disk protects orifices and nozzles against coarse contaminants. W ith severe contamination, the valve response will be reduced.Replace filter!Cleaning the filter is useless and may be dangerous!Before starting to work on the valve, clean the external surface around the filter cover!Attention: The filter disk (21) flows from inside to the outside.After removal of the cover (20) any contamination particles are on the insideof the disk (21) and therefore, cannot be seen from outside.a.Remove four internal hex bolts (38) using A llen wrench (3 mm). Removecover (20). Remove the filter disk (21) now accessible by using a scriber or a fine screwdriver as extraction tool.b.(53) for damage.Replace if necessary.c.Insert o-ring (53) first.

The spring force moves the spool into the defined metering spoolposition.8D691 SeriesInstallation drawing Spare parts, Accessories2nd return port T 2 must be used.With 5-way version the P and T ports are interchanged, i.e. T changes to P , T 2 changes to P 2and P changes to T.than 1µm.7Command signal for pressure p Voltage command 0 to +10 V The controlled load pressure is proportional to (U 9 – U 3). 100 %rated pressure is achieved at +10V input signal.Current command 0 to +10 mA (4 to 20 mA resp.)The controlled load pressure is proportional to I 9. 100% rated pressure is achived at +10 mA (20 mA resp.) input signal.Actual value spool position (Q)Signal levels for actual flow output (U 6 – U 3 and I 6 resp.) are given in the wiring table below.Actual value pressure pSignal levels for actual pressure output (U 10 – U 3 and I 10 resp.) are given in the wiring table below.Note: When the p -potentiome-ter is readjusted with reference to a manometer this output will not change.Wiring for valves with 11+PE pole connectorto DIN 43 651 and mating connector (metal shell) with leading protective grounding connection ()D691 SeriesValve electronics with supply voltage ±15 VoltCommand signal for flow Q Voltage command 0 to ±10 V The spool stroke of the valve is proportional to (U 4 – U 3). 100 %valve opening P ç A und B ç T is achieved at +10 V input signal.At 0 V command the spool is in a centred position.Current command 0 to ±10 mA (4 to 20 mA resp.)The spool stroke of the valve is proportional to I 4 (I 4 – 12 mA resp.). 100 % valve opening P ç A and B ç T is achieved at +10 mA (20 mA resp.) input signal.

Only one load port (A) is used.The device operates like the 3-way PQ-Valve but with doubled flow rate into the load. A directional change of the load motion requires an external force.Without shuttle valve.The device operates from P ç A like a 3-way PQ-Valve. In the opposite direction P ç B it allows only flow modulation. By this means the direction of load motion can be reversed (open loop velocity control for load retract).Venting of pressure transducer Before first operation of the valve the internal lines of the pressure transducer must be carefully vented.When selecting the installation position of the valve care must be taken that the bleeding screw can become effective.If the load is located higher than the PQ-Valve the load also must be vented at its highest point.Caution: Vent only at reduced pressure! Danger of injury!With shuttle valve.The device operates as an electrically adjustable 4-way throttle valve, i. e. the load can be operated with pressure control in both directions of motion.Only one of the load ports is pressure controlled. The shuttle valve transmits the driving (higher) load pressure to the single pressure transducer. An electronic logic circuit provides for the coordination of motion direction and pressure control depending on the polarity of the flow rate command signal. The other port is more or less open to tank line which is provided by the special spool land location.The spring centered fail-safe version requires external pilot supply port X to be used.The device has parallel flow pathes and operates as elec-trically adjustable pressure relief valve from A ç T and B çT 2, res-pectively. At zero command signal the valve is fully open,i. e. the pressure in the load ports is zero apart from minor pres-sure build up due to line losses. A minimum pilot pressure (p X > 15 bar) has to be secured.This can be achieved by a check valve with 15 bar cracking pressure (as shown) or by a separate pilot supply pump.D691 SeriesTypical characteristic curvesFlow and pressure responseFlow step responseFrequency response (flow)Pressure step responseExamples for pressure step response showthe effect of valve flow setting and entrap-ped fluid volume on pressure controldynamics.

If required please contactMOOG for assistance.43Flow rate and pressure dropThe actual flow is dependent upon electrical command signal and valve pressure drop. The flow for a given valve pressure drop can be calculated using the square root function for sharp edged orifices as follows:Flow rate mode An electrical command signal (flow rate set point) is applied to the integrated position controller which drives the valve coil. The position transducer (LVDT) which is excited via an oscillator measures the position of the spool (actual value, position voltage).This signal is then demodulated and fed back to the controller where it is compared with the command signal. The controller drives the pilot valve until the error between command signal and feedback signal is zero. Thus the position of the spool is pro-portional to the electrical com-mand signal.Q [l/min]=calculated flow Q N [l/min]=rated flowD p [bar]=actual valve pressuredropD p N [bar]=rated valve pressuredropQ Q p p NN=∆∆Pressure control mode The afore mentioned flow rate control is superimposed with a pressure limiting control. Both command signals (external flow command signal and limiting pressure command signal) must always be present.The difference between external flow command signal and output signal of the pressure limiting controller results in a spool position command signal. This output signal is zero as long as the actual pressure is smaller than the limiting pressure command value.If the actual pressure value exceeds the limiting pressure command value, the pressure limiting controller reduces the spool position command signal until the actual pressure value equals the limiting pressure command value.If instead of pressure limiting a pressure control has to be installed, the external flow command signal must be selected that high, so that the limiting function actually occurs.This is necessary because the pressure limiting controller can only reduce the spool position command. The external flow command signal should be larger than 30 % of rated signal (see diagrams on page 4).External pilot pressure If large flow rates with high valve pressure drop are required an appropriate higher pilot pressure has to be chosen to overcome the flow forces. An approximate value can be calculated as follows:Q [l/min]=max. flowD p [bar]=valve pressure dropwith Q A K [cm 2]=spool drive area p X [bar]=pilot pressure The pilot pressure p X has to be at least 15 bar above the return pressure of the pilot stage.p QA p X K≥⋅⋅⋅−17102,∆2D691 SeriesProportional Control PQ-ValvesTwo stage withThis catalogue is for users with technical knowledge.

The high pressure recovery of the ServoJet stage (more than 80 % D p at 100 % command signal) provides higher spool driving forces and ensures enhanced spool position The proportional control PQ-Valves D691 Series are dual function valves for 2x2-, 3-, 4- and 5-way applications.The PQ-Valves modulate a fluid flow and control in closed loop a pressure (upper or lower pressure limit). The valves are suitable for pressure control and pressure limiting applications.The control electronics for the spool position and pressure loopsand a pressure transducer are integrated in the valve.For over 15 years MOOG has built PQ-Valves with integrated electronics. During this time more than 30 000 PQ-Valves have been delivered and successfully applied to injection molding, heavy industry, presses and paper processing. The val-ves have proved to be reliable especially when high dynamic performance is required.The valves have been continually developed. With MOOG ’s new ServoJet pilot stage a further step has been taken in the direction of energy saving and robustness.This pilot stage uses the jet pipe principle which for over 8 years has been operating reliably in different MOOG valves.The integrated valve electronics require either 24 Volt DC or a ± 15 Volt DC power supply.The valve series described in this catalogue have suc-cessfully passed EMC tests required by EC Directive.

目前液压系统形成了 ３ 个温度 级别：Ⅰ级 为 － ５ ４～７１ ℃，Ⅱ级为 － ５４～１３５℃，Ⅲ级为 －５４～１９８℃，而 军用飞机液压系统的最高热点温度达 到了 ３１５℃，目前 ６０９所的液压系统电 液伺服阀设计准则都是以Ⅱ级温度范 围为准。随着压力和功率的提高，液压 系统的温度也不断提高。而有些液压 系统如发动机燃油系统温度则是按 － ５５～２１５℃作为设计准则。密封结构和 密封元件是整个液压系统中最薄弱的 环节，因此，解决耐高压、耐高温环境 的密封结构、材料是发展电液伺服阀 的关键技术之一。

伺服阀使用说明书
伺服阀使用说明书伺服阀是DEH控制系统中电液转换的关键元件，它可将电调装置发出的控制指令，转变成相应的液压信号，并通过改变进入油动机油缸液流的方向、压力和流量，来达到驱动阀门、控制机组的目的。
1 结构特点伺服阀是一个由力矩马达、两级液压放大及机械反馈所组成的系统。
第一级液压放大是双喷嘴挡板系统；第二级放大是滑阀系统。
其基本结构如图1所示。
图11.1 力矩马达：一种电气—机械转换器，可产生与电指令信号成比例的旋转运动，用在伺服阀的输入级。
力矩马达包括电气线圈、极靴和衔铁等组件。
衔铁装在一个薄壁弹簧管上，弹簧管在力矩马达和阀的液压段之间起流体密封作用。
衔铁、挡板和反馈杆刚性固接，并由薄壁弹簧管支撑。
1.2 先导级：挡板从弹簧管中间伸出，置于两个喷嘴端面之间，形成左、右两个可变节流孔。
衔铁的偏转带动挡板，从而可改变两侧喷嘴的开启，使其产生压差，并作用于与该喷嘴相通的滑阀阀芯端部。
1.3 功率放大级：由一滑阀系统控制输出流量。
阀芯在阀套中滑动，阀套上开有环行槽，分别与供油腔P和回油腔T相通。
当滑阀处于“零位”时，阀芯被置于阀套的中位；阀芯上的凸肩恰好将进油口和回油口遮盖住。
当阀芯受力偏离“零位”向任一侧运动时，导致油液从供油腔P流入一控制腔（A或B），从另一控制腔（B或A）流入回油腔T。
阀芯推动反馈杆端部的小球，产生反馈力矩作用在衔铁挡板组件上。
当反馈力矩逐渐等于电磁力矩时，衔铁挡板组件被移回到对中的位置。
于是，阀芯停留在某一位置。
在该位置上，反馈力矩等于输入控制电流产生的电磁力矩，因此，阀芯位置与输入控制电流的大小成正比。
1.4 特点：●衔铁及挡板均工作在中立位置附近,线性好●喷嘴挡板级输出驱动力大●阀芯基本处于浮动状态,不易卡住●阀的性能不受伺服阀中间参数的影响,阀的性能稳定,抗干扰能力强,零点漂移小2 工作原理：当力矩马达没有电信号输入时，衔铁位于极靴气隙中间，平衡永久磁铁的磁性力。
当有欲使调节阀动作的电气信号由伺服放大器输入时，力矩马达的线圈中有电流通过，产生一磁场，在磁场作用下，产生偏转力矩，使衔铁旋转，同时带动与之相连的挡板转动，此挡板伸到两个喷嘴中间。

伺服阀的动态特性
在伺服阀中，阀芯由闭环反馈来定位。 喷嘴挡板式伺服阀的反馈信号是由作用于挡板和 弹簧组件上的阀芯位移用机械方法提供的，挡板起 着将来自衔铁的输入信号与来自阀芯位移的反馈信 号进行比较的作用。 伺服阀本身就是一个闭环位置控制系统，可以用 它对阶跃输入的响应或对正弦变化输入的响应（频 率响应）以及传递函数来评定阀的动态特性。

伺服阀的特性及性能参数(精)
第三节伺服阀的特性(tèxìng)及性能参数一．伺服阀规格(guīgé)的标称电波(diàn bō)伺服阀的规格用额定电流I n额定(é dìng)压力和额定(é dìng)流量来标称。
额定电流系产生额定流量所需的任一极性的输入电流，它与压力或力矩马达两个线圈的连接形式（单接、串联、并联或差动连接）有关。
额定压力系产生额定流量的供油压力。
额定流量有两种定义方法：1)以额定空载流量作为额定流量，即以额定电流、额定压力下，负载压力为零时的空载流量来标称额定流量式中-----以为输入、为输出的伺服阀增益，m/A。
2)以规定负载压下的负载流量作为额定流量，即以额定电流、额定压力和规定阀上压降下的负载流量来标称额定流量式中…………阀上总压降，Pa。
为了得到最低的输出功率，常取。
由于高压伺服阀多为Mpa，中压伺服阀为MPa（或6.3 MPa）,于是或2 MPa。
p为7或2MPa时的负载流量来标称额定流量。
所以许多伺服阀常以v对于四通阀来说，单个阀口的压降为阀上压降的一半，因此也有一些中压伺服阀以规定阀口压降p∆＝1MPa时的负载流量来标称额定流量。
可见，不能笼统地谈额定流量，一定要明确是哪种定义及条件下的额定流量。
选用或代用伺服阀时尤其要注意这一点。
〔实例(shílì)〕某引进设备的钢带自动跑偏控制系统，实际油源压力4.5MPa，采用阀口引进pQ＝20L/min的伺服阀。
∆＝1MPa时负载(fùzài)流量L现要改用额定(é dìng)压力 MPa的国产(guóchǎn)伺服阀，问代用阀的额定控制流量应多大？注意，系统实际油源压力为4.5 MPa，因为伺服阀的实际使用(shǐyòng)压力可以等于，也可以低于其额定压力。
由题意知，原系统阀上总压降MPa，不管代用什么阀，新阀的负载流量应等于原阀的负载流量，所以，如果新阀的额定压力为4.5 MPa，则由式（4-15）比式（4-16）得新阀的空载流量应为现在所选代用阀额定压力为6.3 MPa，为了降压到4.5 MPa下使用时仍具有所需的流量，显然应选用额定空载流量更大一些的代用阀，即应取L/min二．伺服阀的静态及动态特性（一）伺服阀的静态特性伺服阀的功率均为滑阀，而力（矩）马达及前置级为比例控制元件，因此伺服阀的一台特性基本上同滑阀的静态特性。
国产伺服阀资料
概述：电液伺服阀是电气－液压伺服控制系统的关键部件，用于位置、速度、加速度和力等的控制。
七O四研究所创建于1956年，隶属于中国船舶重工集团公司，主要从事舰船特辅机电设备的应用研究和设计开发工作，本所技术力量雄厚，拥有中高级科研技术人员500余人，专业技术人员300余人。
早在五十年代已开始研究、开发电气－液压产品。
七十年代开始研制和应用电液伺服阀，并在1981年研制诞生了我国第一台船用射流管电液伺服阀。
经过几代人的不懈努力，本所生产的CSDY型射流管电液伺服阀已成为系列产品。
我们的产品具有结构紧凑、体积小、寿命长、抗污染能力强、动态响应快、分辨率优，适用工作压力范围广等优点，已广泛用于航空、航海、冶金、化工、轻纺、塑料加工、石油冶炼、试验机械、电站设备和机器人等领域。
工作原理：CSDY系列射流管电液伺服阀是力反馈两级流量控制阀（见结构原理图），结构原理图力矩马达采用永磁结构，弹簧管支承着衔铁射流管组件，并使马达与液压部分隔离，所以力矩马达是干式的。
前置级为射流放大器，它由射流管与接受器组成。
当马达线圈输入控制电流，在衔铁上生成的控制磁通与永磁磁通相互作用，于是衔铁上产生一个力矩，促使衔铁、弹簧管、喷嘴组件偏转一个正比于力矩的小角度。
经过喷嘴的高速射流的偏转，使得接受器一腔压力升高，另一腔压力降低，连接这两腔的阀芯两端形成压差，阀芯运动直到反馈组件产生的力矩与马达力矩相平衡，使喷嘴又回到两接受器的中间位置为止。
这样阀芯的位移与控制电流的大小成正比，阀的输出流量就比例于控制电流了。
射流放大器因为没有像双喷嘴－挡板阀放大器的压力负反馈，所以流量和压力增益较高，因此该型阀分辨率极好，低压工作性能亦很好。
射流管电液伺服阀的特点：1、该阀的力矩马达采用整体焊接工艺，结构牢固，能在恶劣环境条件下正常工作。
2、独特的射流管放大器结构可以通过200μm的污染颗粒，而不发生故障。
3、单输入型的前置级如被堵时，伺服阀能自动复零，不会产生错误的“满舵”现象。
