先导控制阀类型DPGKE-6-3C40-D24 (第1级) 先导控制阀是直动式比例阀。设计并优化控制边几何形状,将其用作比例方向阀类型 DPGKE 的先导控制阀。
比例线圈是带可拆卸线圈的耐压密闭油浸式直流线圈。它们可将电流按比例转换为机械力。电流强度的增加会使线圈力适当提高。设置的线圈力在整个控制行程内保持不变。
先导控制阀基本由阀体(1),比例线圈(2和3),阀芯(4)和弹簧(5和6)组成。在断电情况下,两个执行机构油口都连接到油箱。如果两个线圈中的一个(2或3)断电, 则线圈力将阀芯(4)向弹簧(5或6)移动。一旦越过遮盖区域,则会堵塞两个执行机构油口之一与油箱的连接,并建立连接压力腔。流体从 P 流向主级的控制腔。
阀门特点
类型DPGKE阀是2级比例方向控制阀。它们控制流体的尺寸和方向。
主级由闭环位置控制,以便阀芯位置也独立于较大流量的液动力。这种阀基本由先导控制阀(1),阀体(8),主阀芯(7),盖 (5和6),对中弹簧(4),感应式位置感测器(9) 和减压阀(3)组成。

如果没有施加输入信号,则主阀芯 (7)就会被对中弹簧(4)保持在位置。盖 (5和6)中的两个控制腔通过阀芯 (2)连接到油箱上。
主阀芯(7)通过感应式位置传感器(9)连接到合适的控制电子元件上。主阀芯(7)的位置改变以及放大器求和点控制值的改变,都能生成差动电压。
借助控制值/实际值比较,通过电子元件识别可能的控制偏差,且电流施加于先导阀(1)的比例线圈。
流动力转而起动控制阀芯。通过阀芯控制节流面提供的流量会移动主阀芯。
连接感应式位置感测器(9)铁芯的主阀芯(7)会一直移动,直到实际值与控制值相等。在闭环控制情况下,主阀芯 (7)被强制平衡,且保持在此闭环控制位置。
阀芯行程和控制开口与控制值成比例改变。
控制电子元件集成到阀中。通过匹配阀和电子元件,产品系列种类的数量一直很少。
防止油箱管路排空;在适当的安装条件下,应安装一个背压阀(背压约为2 bar)。
