3DREPE6C-20=25EG24N9K31/F1M=00比例减压阀 德国博世力士乐REXROTH比例阀 比例减压阀

结构原理

输入信号加大，供气用电磁阀先导阀1换向，而排气用电磁先导阀7处于复位状态，则供气压力从SUP口通过阀1进入先导室5，先导室压力上升，气压力作用在膜片2的上方，则和膜片2相连的供气阀芯4便开启，排气阀芯3关闭，产生输出压力。此输出压力通过压力传感器6反馈至控制回路8。在这里，与目标值进行快速比较修正，知道输出压力与输入信号成一定比例为止，从而得到输出压力与输入信号的变化成比例的变化。由于没有喷嘴挡板机构，故阀对杂质不敏感，可靠性高。

 

特点

1)可实现压力、速度的无较调节，避免了常通的开关式气阀换向时的冲击现象。

2)能实现远程控制和程序控制。

3)与断续控制相比，系统简化，元件大大减少。

4)与液压比例阀相比，体积小、重量轻、结构简单、成本较低，但响应速度比液压系统慢得多，对负载变化也比较敏感。

5)使用功率小、发热少、噪声低。

6)不会发生火灾，不污染环境。受温度变化的影响小。

比例阀三种形态

（1）电磁式 电磁式是指采用比例电磁铁作为电气一机械转换元件的比例阀，比例电磁铁将输入的电流信号转换成力、位移机械信号输出．进而控制压力、流量及方向等参数。

（2）电动式 电动式是指采用直流伺服电动机作为电气一机械转换元件的比例阀，直流伺服电动机将输入的电信号．转换成旋转运动转速，再经丝杆螺母、齿轮齿条或齿轮凸轮等减速装置和变换机构，输出力与位移，进一步控制液压参数。

（3）电液式 电液式是指采用力矩马达和喷嘴挡板的结构为先导控制级的比例阀。对力矩马达输入不同的电信号，并通过同它连接在一起的挡板（有时力矩马达的衔铁就是挡板）输出位移或角位移，改变挡板和喷嘴之间的距离，使喷嘴喷出的油液流阻产生变化，进而控制输小参数。

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。

力士乐REXROTH三通结构的比例减压阀，先导式3DRE(M)

电磁阀是用来控制流体的自动化基础元件，属于执行器；并不限于液压，气动。对于一台泵的转速，实际上是有限制的，这主要取决于工艺流体，如果传送的是油类，泵则能以很高的速度转动，但当流体是一种高粘度的聚合物熔体时，这种限制就会大幅度降低。
