MOOG_DDV阀_资料(中文)
MOOGMOOG(穆格)DDV伺服阀MOOG(穆格)D633、D634系列伺服阀是MOOG公司最新研制成功的新型电液伺服阀，目前已由MOOG GmbH(德国)公司进行批量生产。
它是一种直接驱动式伺服阀，简称DDV(Direct Drive Servo Valve的缩写)，油口与安装尺寸D633按NG6(Cetop 3),D634按NG10(Cetop 5)，用集成电路实现阀芯位置的闭环控制，阀芯的驱动装置是永磁直线力马达。
对中弹簧使阀芯保持在中位，直线力马达克服弹簧的对中力使阀芯在两个方向都可偏离中位，平衡在一个新的位置，这样就解决了比例电磁线圈只能在一个方向产生力的不足之处。
阀芯位置闭环控制电子线路与脉宽调制（PWM）驱动电子线路固化为一块集成块，用特殊的连接技术固定在伺服阀内，因此D633、D634系列伺服阀无需配套电子装置就能对其进行控制。
D633、D634系列伺服阀是MOOG公司对其经久考验，盛名于世的双喷嘴力反馈两级伺服阀的发展与补充，和传统的MOOG30、31、32、34、35、E760等系列伺服阀相比，其最大的区别在于D633、D634系列伺服阀从结构上取消了喷嘴一挡板前置级、用大功率的直线力马达替代了小功率的力矩马达，用先进的集成块与微型位置传感器替代了工艺复杂的机械反馈装置—力反馈杆与弹簧管，从而简化了结构，提高了可靠性，大大地降低了制造成本，却保持了带喷挡前置级的两级伺服阀的基本性能与技术指标。
MOOG DDV伺服阀的特点1．在位置、速度、压力以及力电液伺服系统中可用二位二通、三位三通或三位四通的方式进行工作。
2．安装形式与尺寸符合DIN24340和cetop3与6。

ELECTRICAL INFORMATION AND INTRINSICALLY SAFE CIRCUIT SAFETY PARAMETERSa. A wide choice of coils is available for a variety of rated currentrequirements. The torque motor coil leads are attached to the connector so external connections can provide series, parallel or single coiloperation. The valves are equipped either with an MS type connector or with pigtail leads for electrical wiring. Refer to installation drawings of the specific model for details. Servovalve coils should be driven with current to provide consistency throughout the temperature range.b. The (G)72K valves are approved for intrinsically safe protection per EN60079-11. The approved safety parameters are listed in the following table for all the coils used by (G)72K series. Coil number is marked on thevalve nameplate.Coil Configuration Marking U i (MAX) I i (MAX) G4220-031 (single, series, parallel) Ex ia IIB T4 12 V 120 mAG4220-051/098 (single, series, parallel) Ex ia IIB T4 12 V 240 mAG4221-001 G4220-042 (single) Ex ia IIC T4 16 V 160 mA G4221-001 G4220-042 (single) Ex ia IIC T4 24.4 V 85 mAG4220-031 (single, parallel) Ex ia IIC T4 30 V 26 mAG4220-031 (series) Ex ia IIC T4 30 V 18 mAG4220-051/098 (single, parallel) Ex ia IIC T4 30 V 19 mA G4220-051/098 (series) Ex ia IIC T4 30 V 12.7 mAG4220-042 (single) Ex ia IIC T4 30 V 37 mAG4220-042 (parallel) Ex ia IIC T4 30 V 20 mAG4220-042 (series) Ex ia IIC T4 30 V 10 mAG4221-001 (single) Ex ia IIC T4 30 V 28 mAc. The (G)72K valves are approved for non-incendive operation for supplycurrent not to exceed 50 mA dc.d. When making electric connections to the valve, appropriate measures mustbe taken to ensure that locally different earth potential do not result inexcessive ground currents. When barriers are required for the hazardous location, hazardous area (field) wiring must meet the requirements ofthe barrier manufacturer. All barriers must be mounted and installed incompliance with the barrier manufacturer’s requirements. Twisted pairs of 18-20 gage wire are recommended. If shielded wire is used, connect shield wire to earth ground only at the barrier strip.4. SPECIAL CONDITIONS FOR SAFE USEBecause the enclosure of the apparatus is made of aluminum, if it is mounted in an area where the use of category 1 G apparatus is required, it must be installed such that even in the event of rare incidents, ignition sources due to impact and friction sparks are excluded.When the electrohydraulic servovalve is used in an application for type of explosion protection intrinsic safety “i”, the appropriate box on the data label must be scored. When the electrohydraulic servovalve is used in an application for type of explosion protection “n”, the appropriate box on the data label must be scored.After use in an application for type of explosion protection “n”, the servovalve cannot abe safely used in a intrinsically safe application.The screwed cable connector may only be disconnected when the circuit is de-energized or when the location is known to be non-hazardous.When used at an ambient temperature ≥70°C, heat resistant cable must be used with a continuous operating temperature in accordance with the application.5. HYDRAULIC SYSTEM PREPARATIONTo prolong servovalve operational life and to reduce hydraulic system maintenance, it is recommended that the hydraulic fluid be kept at a cleanliness level of ISO DIS 4406 Code 16/13 maximum, 14/11 recommended. The most effective filtration scheme incorporates the use of a kidney loop or “off-line” filtration as one of the major filtration components. The filter for the “off-line” filtration scheme should be a ß3≥75 filter for maximum effectiveness.Upon system startup and prior to mounting the servovalve, the entire hydraulic system should be purged of built-in contaminating particles by an adequate flushing. The servovalve should be replaced by a flushing manifold and the hydraulic circuit powered up under conditions of fluid temperature and fluid velocity reasonably simulating normal operating conditions. New system filters are installed during the flushing process whenever the pressure drop across the filter element becomes excessive. The flushing processes should turn over the fluid in the reservoir between fifty to one hundred times.To maintain a clean hydraulic system, the filters must be replaced ona periodic basis. It is best to monitor the pressure drop across the filter assembly and replace the filter element when the pressure drop becomes excessive. In addition to other filters that are installed in the hydraulic circuit, it is recommended that a large capacity, low pressure ß3≥75 filter be installedin the return line. This filter will increase the interval between filter element replacements and greatly reduce the system contamination level.6. INSTALLATIONThe Moog (G)72K series industrial servovalve may be mounted in any position, provided the servovalve pressure, control, and tank ports match respective manifold ports. The mounting pattern and port location of the servovalve is shown on Figure 4. The servovalve should be mounted with 3/8-16 x 2.00 inch long, socket head cap screws. Apply a light film of oil to the screw threads and torque to 175 inch-pounds. Wire mating connector for desired coil configuration and polarity. Thread connector to valve.7. MECHANICAL NULL ADJUSTMENTIt is often desirable to adjust the flow null of a servovalve independent of other system parameters. The “mechanical null adjustment” on the Moog (G)72K Series servovalve allows at least ±20% adjustment of flow null. The “mechanical null adjustor” is an eccentric bushing retainer pin, located above the tank port designation on the valve body (see Figure 2) which, when rotated, provides control of the bushing position. Mechanical feedback elements position the spool relative to the valve body for a given input signal. Therefore, a movement of the bushing relative to the body changes the flow null. Mechanical Adjustment ProcedureUsing a 3/8 inch offset box wrench, loosen the self-locking fitting until thenull adjustor pin can be rotated. (This should usually be less than 1/2 turn). DO NOT remove self-locking fitting. Insert a 3/32 inch Allen wrench in null adjustor pin. Use the 3/32 Allen wrench to rotate the mechanical null adjustor pin to obtain desired flow null. Torque self-locking fitting to 57 inch lbs. Note:Clockwise rotation of null adjustor pin produces flow from port P to port B.Tools and Equipmenta. Blade screwdriverb.

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.

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.
