三口电比例减压/溢流阀– PRDL 和 PRDM
标准的减压/溢流阀PRDL和反向作用的减压/溢流阀PRDM都拥有 负遮盖的阀芯,这将使得阀在减压功能向溢流功能转换的过程中 有油液泄露。这类阀较于PRDP和PRDN有相似的性能,除了以下 几点: 这种负遮盖的阀芯设计将会提高阀的动态响应。 阀芯这种带有油液导通的动作方式会产生更大的泄露 0.1gpm (0.4L/min)。(在无通流的压力保持回路中,此泄漏是个影

See the CONFIGURATION section.SFPB*PILOT-OPERATED ELECTRO-PROPORTIONAL THROTTLE VALVETECHNICAL FEATURESThe 2/2 proportional poppet valves are pilot operated. Theycomprise a hex body (3), solenoid with coil (2), poppet (5), dart (4), coil nut (1), ball (6), pin (7), and two springs (8 & 9) for the FPBG and FPBF, and one spring (8) for the FPBJ and FPBI .FPBG & FPBF (normally closed)Function: When de-energized, the dart (4) rests on the poppet (5) which in turn rests on the sleeve seat (3). In this condition, flow is blocked from 2 to 1 but will free flow from 1 to 2. When energized, the dart lifts from the poppet propor-tional to the coil current. The poppet then follows the dart and lifts from the seat, opening flow from 2 to 1.If the FPBF is open and flow is routed 1 to 2, the valve will auto close and only pilot flow will pass from 1 to 2. For the FPBG, the check valve (6 & 7) at the nose of the poppet will allow free flow 1 to 2 whether the valve is open or closed.FPBJ & FPBI (normally open)Function: When de-energized, the dart (4) and poppet (5) are held away from the sleeve seat by the spring (8), opening flow from 2 to 1. When energized, the dart pushes into the poppet seat proportional to the coil current. As the dart pushes against the spring, the poppet pushes into the sleeve seat, closing the valve. Flow is then blocked from 2 to 1 but can free flow from 1 to 2.If the FPBI is open and flow is routed from 1 to 2, the valve will auto close and only pilot flow will pass from 1 to 2. For the FPBJ, the check valve (6 & 7) at the nose of the poppet will allow free flow 1 to 2 whether the valve is open or closed.C M A /F l o d y n e /H y d r a d y n e ▪ M o t i o n C o n t r o l ▪ H y d r a u l i c ▪ P n e u m a t i c ▪ E l e c t r i c a l ▪ M e c h a n i c a l ▪ (800) 426-5480 ▪ w w w .c m a f h .c o m747High-power coilsDIN or Deutsch connector 12, 14, 24, or 28 VdcWith or without TVS diode 740X D N74*Hazardous location coils Explosion-proofCSA, ATEX, IECEx certified 12, 24 VdcSee individual coil data sheets for full coil configuration.Important Note :When performing model code searches on , do not include setting(s).

德国哈威PSL型比例多路阀工作原理
德国哈威(HAWE)PSL型比例多路阀基本工作原理该阀为负载感应工作阀片,含二通压力补偿定差减压阀,负载感应梭阀,安全溢流阀,电磁溢流阀,比例减压阀。
通常,工作阀片成组配置,进口阀块内置三通压力补偿旁通溢流阀(逻辑元件,当多路阀停止操作,且各阀均在中位时,该阀则以补偿压力(6-·12BAR)旁通主油路流量。
当某一阀工作时,该阀在负载压力作用下旁通口减少,根据负载压力提供所需的流量。
负载感应梭阀:负载感应梭阀将各工作阀片的负载压力传至进口阀块的压力补偿旁通溢流阀。
二通压力补偿定差减压阀:当多个工作片阀同时工作时,负载压力传至该阀的弹簧侧。
此时,通过阀心的负反馈作用,来自动调节节流阀口两端的压力差, 使其基本保持不变。
在其作用下各阀的流量均保持恒定,且不受负载变化的影响。
安全溢流阀:通常用于工作机构极限保护,例如变幅油缸。
电磁溢流阀:用于工作机构的超限保护,例如:起重机的力矩限制,三圈保护等。
比例减压阀:位于工作阀片手拉杆的相对一侧,为直动式比例减压阀,驱动滑阀实现比例换向,注意:直动式比例减压阀的比例换向相对于手动比例换向,微动性能不好,若用于流量控制精度较高的应用,应采用比例伺服驱动配置的工作阀片。
REXROTH, BUCHER, DELTA POWER, SAUER-DANFOSS 均有伺服驱动的比例多路阀。
该阀手动比例多路阀为全负载感应阀和非负载感应混合配置阀组该阀手动比例多路阀为全负载感应阀和非负载感应混合配置阀组,可以实现单支路和多支路同步工作。
左侧第一片阀为进口阀片,从下向上,(1) CP3三通式定差旁通式压力补偿流量阀,(2)RV安全溢流阀, 通常设定为系统最高压力35Mpa,(3)RPM减压阀为工作阀片的比例减压阀提供先导供油(1.5-2.5Mpa),可以看到减压阀下的一条虚线连线两条虚线,并连通每个工作阀片的一对比例减压阀。
工作片阀位于中位不工作时,CP3功能等同于流量旁通控制阀。

The reference variable w (setpoint val-ue, e.g. 5 V or 8 mA) initially acts on a comparator. The measuring equipment sends the controlled variable x value (actual value, e.g. 3 bar) to the com-parator as a feedback signal r. The closed-loop control element detects the system deviation e and actuates the final control element. The output of the final control element acts on the controlled system. The closed-loopcontrol element thus attempts to com-pensate for the difference between thereference variable w and the controlledvariable x by using the final controlelement.This process runs continuously sochanges in the reference variable arealways detected. However, a systemdeviation will also occur if the refer-ence variable is constant and the con-trolled variable changes. This happenswhen the flow through the valve chang-es in response to a switching opera-tion, a cylinder movement or a loadchange. The disturbance variable z willalso cause a system deviation. Anexample of this is when the pressuredrops in the air supply. The distur-bance variable z acts on the controlledvariable x in an unforeseen way. In allcases, the closed-loop controllerattempts to correct the controlledvariable x to the reference variable w.Multi-sensor control (cascade control) of the VPPMCascade controller Control precisionUnlike conventional direct-acting con-trols, in multi-sensor controls multiple control loops are nested inside one other. The overall controlled system is divided into smaller sub-sections that are easier to control for the specifictask.Control accuracy and dynamic re-sponse are greatly improved with themulti-sensor control principle in com-parison with a single-acting regulator.52023/08 – Subject to change d Internet: /catalogue/...Proportional-pressure regulators VPPMKey features – Control loop6d Internet: /catalogue/...Subject to change – 2023/0872023/08 – Subject to changed Internet: /catalogue/...Proportional-pressure regulators VPPMKey features – Flow rateFlow rate qn of 1 d 2 as a function of excess output pressure p2VPPM-6L/F-...-0L2H-...(2 bar)VPPM-6L/F-...-0L6H-...(6 bar)VPPM-6L-...-OL2H-...qn1-2[l/min]7515022530037545052560000.20.40.60.811.21.41.61.82VPPM-6L-...-OL6H-...qn1-2[l/min]p 2[b a r ]150300450600750900105012000.61.21.82.433.64.24.85.56VPPM-6L/F-...-0L10H-...(10 bar)VPPM-6L-...-OL10H-...qn1-2[l/min]2004006008001000120014001600012345678910Flow rate qn of 2 d 3 as a function of excess output pressure p2VPPM-6L/F-...-0L2H-...(2 bar)VPPM-6L/F-...-0L6H-...(6 bar)VPPM-6L-...-OL2H-...p2[bar]q n 2-3[l /m i n ]0.20.40.60.811.2 1.4 1.6 1.82050100150200250300350VPPM-6L-...-OL6H-...p2[bar]00.51 1.52 2.53 3.54 4.55 5.56100200300400500600700800VPPM-6L/F-...-0L10H-...(10 bar)VPPM-6L-...-OL10H-...p2[bar]q n 2-3[l /m i n ]0123456789100200400600800100012008d Internet: /catalogue/...Subject to change – 2023/08Proportional-pressure regulators VPPMKey features – Flow rateFlow rate qn of 1 d 2 as a function of excess output pressure p2VPPM-8L...-0L2H-...(2 bar)VPPM-8L-...-0L6H-...(6 bar)VPPM-8F-...-OL2H-...qn1-2[l/min]200400600800100000.20.40.60.811.21.41.61.82VPPM-8L-...-OL6H-...qn1-2[l/min]p 2[b a r ]5001000150020002500300000.61.21.82.433.64.24.85.46VPPM-8L-...-0L10H-...(10 bar)VPPM-8L-...-OL10H-...qn 1-2[l/min]500100015002000250030003500012345678910Flow rate qn of 2 d 3 as a function of excess output pressure p2VPPM-8L-...-0L2H-...(2 bar)VPPM-8L-...-0L6H-...(6 bar)VPPM-8L-...-OL2H-...p2+[bar]q n 2-3[l /m i n ]0.20.40.60.811.2 1.4 1.6 1.82100200300400500600700800VPPM-8L-...-OL6H-...p2+[bar]q n 2-3[l /m i n ]0.6 1.2 1.8 2.433.64.2 4.85.46200400600800100012001400160018002000VPPM-8L-...-0L10H-...(10 bar)VPPM-8L-...-OL10H-...p2+[bar]q n 2-3[l /m i n ]1234567891050010001500200025003000350092023/08 – Subject to changed Internet: /catalogue/...Proportional-pressure regulators VPPMKey features – Flow rateFlow rate qn of 1 d 2 as a function of excess output pressure p2VPPM-8F/8TA-...-0L2H-...(2 bar)VPPM-8F/8TA-...-0L6H-...(6 bar)VPPM-8L-...-OL2H-...qn 1-2[l/min]20040060080010001200140000.20.40.60.811.21.41.61.82VPPM-8F-...-OL6H-...qn 1-2[l/min]p 2[b a r ]2505007501000125015001750200000.61.21.82.433.64.24.85.46VPPM-8F/8TA-...-0L10H-...(10 bar)VPPM-8F-...-OL10H-...qn 1-2[l/min]5001000150020002500012345678910Flow rate qn of 2 d 3 as a function of excess output pressure p2VPPM-8F/8TA-...-0L2H-...(2 bar)VPPM-8F/8TA-...-0L6H-...(6 bar)VPPM-8L-...-OL2H-...p2+[bar]q n 2-3[l /m i n ]0.20.40.60.811.2 1.4 1.6 1.820100200300400500600VPPM-8L-...-OL6H-...p2+[bar]q n 2-3[l /m i n ]0.6 1.2 1.8 2.433.64.2 4.85.460200400600800100012001400VPPM-8F/8TA-...-0L10H-...(10 bar)VPPM-8L-...-OL10H-...p2+[bar]q n 2-3[l /m i n ]0123456789100500100015002000250010d Internet: /catalogue/...Subject to change – 2023/08Proportional-pressure regulators VPPMKey features – Flow rateFlow rate qn of 1 d 2 as a function of excess output pressure p2VPPM-12L-...-0L2H-...(4 bar)VPPM-12L-...-0L6H-...(8 bar)qn1-2[l/min]p 2[b a r ]1000200030004000500000.20.40.60.811.21.41.61.82qn1-2[l/min]1000200030004000500060007000800000.511.522.533.544.555.56VPPM-12L-...-0L10H-...(11 bar)qn1-2[l/min]p 2[b a r ]200040006000800010000012345678910Flow rate qn of 2 d 3 as a function of excess output pressure p2VPPM-12L...-0L2H-...(4 bar)VPPM-12L-...-0L6H-...(8 bar)p2[bar]q n 2-3[l /m i n ]0.20.40.60.811.2 1.4 1.6 1.822505007501000125015001750200022502500p2[bar]00.51 1.52 2.53 3.54 4.55 5.5650010001500200025003000350040004500500055006000VPPM-12L-...-0L10H-...(11 bar)p2[bar]q n 2-3[l /m i n ]1234567891010002000300040005000600070008000900010000Individual valve VPPM-6L ... , VPPM-8L ...8Individual valve VPPM-12L ...Valve manifold assembly with VPPM-6F ... , VPPM-8F ...System overviewVPPM-6TA ... , VPPM-8TA ...for valve terminal MPA-S15Type codes-M-Flow rate380 ... 7000 l/min -P- Voltage21.6 ... 26.4 V DC-L-Pressure regulation range0.002 ... 1 MPa0.02 ... 10 bar Variants• Setpoint input as analogue voltage signal 0 ... 10 V• Setpoint input as analogue current signal 4 ... 20 mA• LED version• With LCD display ( (1)•Switching output NPN (N) or PNP (P)H--NoteOutput pressure will be unregulated if the power supply cable is interrupted.1)Input pressure 1 should always be 1 bar greater than the maximum regulated output pressure.2)Corrosion resistance class CRC 2 to Festo standard FN 940070Moderate corrosion stress.

哈威HAWE溢流阀的工作原理两个点来描述
哈威HAWE溢流阀的工作原理两个点来描述哈威HAWE溢流阀的工作原理两个点来描述,详情如下:很多用户不了解哈威HAWE溢流阀工作原理。
下面小编就来简单介绍不同的哈威HAWE溢流阀工作原理。
有需要的用户们来简单的了解一下吧!1、哈威HAWE先导式溢流阀是由先导阀和主阀组成。
先导阀用以控制主阀芯两端的压差,主阀芯用于控制主油口的溢流。
目前应用广泛的先导式溢流阀按阀芯结构形式,可分为三节同心式和二节同心式两种结构。
2、在定量泵节流调节系统中,定量泵提供的是恒定流量。
当系统压力增大时,会使流量需求减小。
此时溢流阀开启,使多余流量溢回油箱,保证哈威HAWE溢流阀进口压力,即泵出口压力恒定(阀口常随压力波动开启)。
安全保护作用:系统正常工作时,阀门关闭。
只有负载超过规定的极限(系统压力超过调定压力)时开启溢流,进行过载保护,使系统压力不再增加(通常使溢流阀的调定压力比系统高工作压力高10%~20%)。
下面再为介绍一下哈威HAWE溢流阀的产品内容:哈威HAWE溢流阀可对液压回路中的系统压务实现电比例调节.显然,在断电状况,系统将处于低压力.此压力值取决于流量(流阻压降)或通过调节螺钉设定的最小值(见第2节)PMV(P)S型的特点是,控制油为外控,与主油路分开(约200bar).哈威HAWE溢流阀它的应用主要包括;用于高压系统,以提高压力控制器件的寿命用于很低压力(0--5bar)场合,能籍助于控制压力保持阀的可调性。
用于高压系统主回路,可长时间保压而无控制油损失(译注;普通先导式比例压力阀工作时,始终存在先导油的损失,而本比例阀由于是用三通比例减压阀进行控制,在正常运行时,不存在这种先导油的损失(调节过程除外)。
控制回路大约需要1 L/min的控制流量,控制油将由例如;径向柱塞泵单独的压力出口提供,径向柱塞泵要符全D6010S的要求这类阀需要比例放大器进行控制哈威HAWE溢流阀的结构:PMV(P)和PMV(P)S型阀是直接作用式(译注;其两级三通减压阀作先导级,只是用来代替手轮对弹簧预紧力进行调节,从这个意义上讲是直接作用式)比例溢流阀,它包括主阀(球阀,弹簧,控制柱塞)和直接安装在主阀上的比例控制组件(比例减压阀,和初级减压阀)组成。

Parker Hannifin 电压调节阀DPR083B系列技术说明说明书
General DescriptionThe DPR083B Series Valve is a normally-closed valve used for reducing inlet pressure to 20.7 Bar (300 PSI) (depending on model and coil wattage). A common application of this valve is as a transmission-shifter valve where a fixed regulated pressure is required regardless of inlet pressure.OperationWith the solenoid coil de-energized, the spool is held in a closed position by spring force. In this mode, the regulated pressure port is open to tank and the pressure inlet port is blocked. As a voltage signal is applied to the solenoid coil, the spool will begin to travel to a position where the pressure inlet port is connected to the regulated pressure port. At this point, reduced pressure becomes a function of the voltage signal. As long as the voltage signal is constant, thereduced pressure at the regulated pressure port will remain fixed regardless of any changes in inlet flow or inlet pressure. As the voltage signal increases or decreases, the reduced pressure at the regulated pressure port will change with respect to the change in the voltage signal. Once a full voltage signal is given, the reduced pressure of the regulated pressure port will be at the maximum reduced pressure for that valve (i.e. 20.7 Bar (300 PSI).Features•Direct acting design•Adaptable to regulated analog or PWM •Contamination tolerant•Numerous coil terminals and voltages•One-piece encapsulated coil•Standard valve bodies and common cavities •Manual override standard.

溢流阀解析ppt课件
第三节 压力控制阀
压力控制阀简称压力阀,是利用作用在阀芯上的 液压力和弹簧力相平衡的原理工作的。
压力阀包括: (1)用来控制液压系统压力的阀类。 (2)利用压力变化作为信号来控制其它元件动 作的阀类。
按其功能和用途不同可分为溢流阀、减压阀、 顺序阀和压力继电器等。
溢流阀
溢流阀的主要用途有以下两点: 1)调压和稳压。如用在由定量泵构成的液压源中,用以调 节泵的出口压力,保持该压力恒定。 2)限压。如用作安全阀,当系统正常工作时,溢流阀处于 关闭状态,仅在系统压力大于其调定压力时才开启溢流,对 系统起过载保护作用。

阀芯处于中位时, P,A,B,T 四个油口均被封闭,其特点是:
①缸的两腔被封闭,活塞在任一位置均可停住, 且能承受 一定的正向负载和反向负载。
② 因P口封闭,泵不能卸荷 ,泵排出的压力油只能从溢 流阀排回油箱。
③可用于多个换向阀并联的系统。当一个分支中的换 向阀处于中位时, 仍可保持系统压力,不致影响其它分 支的正常工作。

2.机动换向阀 此类控制方式的“信号源”是缸的运动件。例如将挡块
固定在运动的活塞杆上,当挡块触压阀推杆2的滚滚轮1时 , 推杆2即推动阀芯3换向。挡块和推杆2端部的滚轮脱离接触 后,阀芯即可靠弹簧复位。此种阀的控制方式因和缸的行程 有关,也有管此类阀叫“行程阀”。
