性能

(1)调压范围：它是指减压阀输出压力P2的可调范围，在此范围内要求达到规定的精度。调压范围主要与调压弹簧的刚度有关。

(2)压力特性：它是指流量g为定值时，因输入压力波动而引起输出压力波动的特性。输出压力波动越小，减压阀的特性越好。输出压力必须低于输入压力—定值才基本上不随输入压力变化而变化。

(3)流量特性：它是指输入压力—定时，输出压力随输出流量g的变化而变化的持性。当流量g发生变化时，输出压力的变化越小越好。一般输出压力越低，它随输出流量的变化波动就越小

减压阀是通过调节，将进口压力减至某一需要的出口压力，并依靠介质本身的能量，使出口压力自动保持稳定的阀门。从流体力学的观点看，减压阀是一个局部阻力可以变化的节流元件，即通过改变节流面积，使流速及流体的动能改变，造成不同的压力损失，从而达到减压的目的。然后依靠控制与调节系统的调节，使阀后压力的波动与弹簧力相平衡，使阀后压力在一定的误差范围内保持恒定。

比例阀与放大器配套使用放大器采用电流负反馈,设置斜坡信号发生器阶跃函数发生器、PD调节器反向器等,控制升压降压时间或运动加速度及减速度。断电时, 能使阀芯处于安全位置。

比例电磁铁和液压阀组成电液比例阀。由于比例电磁铁可以在不同的电流下得到不同的力(或行程),因此可以无级改变压力、流量。故比例电磁铁是比例阀的关键元件。

产品说明

DRE(M)E 型阀门属于先导式减压阀。这些阀可用于降低工作压力。

这些阀门的基本构成是带比例电磁铁 (2) 的先导控制阀 (1)、带主阀心 (4) 的主阀 (3)，以及可选单向阀 (5)。在比例电磁铁上，还配备带控制电子元件的壳体 (23)。将电源电压和控制值电压施加于连接器 (24)。在出厂时已按照非常低的制造公差对控制值压力特性曲线进行了调节。

型号 DREE...

可通过比例电磁铁 (2) 根据控制值设置通道 A 中的压力。

在静止位置时 – 即通道 B 中没有压力时 – 弹簧 (17) 将主阀芯 (4) 保持在其初始位置。从通道 B 到通道 A 的连接关闭。因此可避免启动跃变。

施加在通道 A 中的压力通过孔 (6) 作用于主阀芯的面 (7)。先导油从通道 B 穿过孔 (8) 流到恒定电流控制 (9) 处，恒定电流控制保持先导流量恒定，与通道 A 和 B 之间的压降无关。先导流量从

恒定电流控制 (9) 处流入弹簧腔 (10)，穿过孔 (11) 和 (12)，通过阀座 (13) 流进通道 Y（14、15、16）并由此回流。通过相关放大器对通道 A 中所需压力进行预设。比例电磁铁将阀架 (20) 向阀座 (13) 方向移动，并将弹簧腔 (10) 中的压力限制为设定值。如果通道 A 处压力低于预设控制值，则弹簧腔 (10) 内的较高压力将会令主阀芯右移。从 B 到 A 的连接打开。如果已达到 A 处的调定压力，此时主阀芯处的力达到平衡 - 主阀芯处于控制位置。

通道 A 的阀芯端面 (7) 处压力 = 弹簧腔 (10) 阀芯端面处压力 – 弹簧力 (17)

如果在立式液压油柱（例如，切断位置的液压缸活塞）中，要降低 A 处压力（例如），则可以通过控制电子元件预设较低的控制值，这样即可预选出较低的压力值，该压力值将立刻出现在弹簧腔 (10) 内。作用于主阀芯表面 (7) 的 A 处的较高压力值将主阀芯推向保护塞 (18) 的方向，到达切断位置。A 到 B 的连接堵塞，A 到 Y 的连接打开。弹簧 (17) 处的力当前反向作用于主阀芯表面 (7) 的液压力。在此主阀芯位置处，液压油可从通道 A 经控制边 (19) 流向 Y，进入回流。

当 A 处压力降至弹簧腔 (10) 中的压力和弹簧 (17) 的 ?p 之和时，主阀芯将关闭控制边 A 到 Y 处插口中的大控制孔。

相对于 A 处新控制值的剩余压差约为 10 bar，当前压力只可通过***控制孔 (21) 卸载。如此即可在无压力下冲情况下实现良好瞬态响应。为实现由通道 A 到通道 B 的自由回流，可选择安装单向阀 (5)。通道 A 处部分充液流量同时可通过打开的主阀芯 A 到 Y 的控制边 (19) 流入回流。

型号 DREME...

为了提供液压保护，防止比例电磁铁上出现不允许的高电气控制电流，导致油口 A 产生超额压力，可以选择安装一个弹簧负载溢流阀 (22)，用于限制压力。此压力限制为基于相关压力等级所设预设值（请参阅表格）。

溢流阀是压力控制阀。其作用主要是控制系统压力，以保护油泵和油路系统的安全及保持油路系统的压力恒定。通经为8毫米的溢流阀是一个小型的直接动作的溢流阀，可以和主溢流阀的遥控口连接，对主溢流阀实现远程压力调节。溢流阀的遥控口经换向阀和油箱连接时，可使油路卸荷。此时溢流阀起卸荷作用。溢流阀的遥控口串联换向阀和通经为8毫米的溢流阀时，可实现压力的多级控制。
