DB10-1-50/100先导式溢流阀

先导式溢流阀

结构:先导调压部分:控制主阀的溢流压力；主阀部分:溢流

工作原理:

利用主阀芯上下两端液体压力差与弹簧力相平衡的原理来进行压力控制。

特点:

①因为锥阀作用面积很小，即使压力很高，弹簧刚度仍不大，调压轻便;

②因为主阀弹簧很软，因此溢流量变化时，压力波动小。静态特性好;

③能适应各种不同的调压范围的要求;

④主阀芯采用锥面阀座式结构密封，没有搭合量，动作灵敏。

先导阀和主阀阀芯分别处于受力平衡，其阀口都满足压力流量方程。阀的进口压力由两次比较得到，压力值主要由先导阀调压弹簧的预压缩量确定，主阀弹簀起复位作用。

通过先导阀的流量很小，是主阀额定流量的1%因此其尺寸很小，即使是高压阀，其弹簧刚度也不大。这样一来阀的调节性能有很大改善。

主阀芯开启是利用液流流经阻力孔形成的压力差。阻力孔一般为细长孔，孔径很小0=0.8~1.2mm,孔长I = 8~12mm,因此工作时易堵塞，一旦堵塞则导致主阀口常开无法调压。

溢流阀遥控口接法

先导阀前腔有一遥控口，在该控制口接远程调压阀可实现远控，接电磁阀通回油箱可实现卸载。

远程调压阀实际上是一个单独的压力先导阀，旁接在先导型溢流阀遥控口起远程调压作用，其调定压力必须低于先导阀的调定压力。无论哪个起作用，泵的溢流量始终经主阀阀口回油箱。

DB10-1-50/100先导式溢流阀

DB 型压力阀是一种先导式溢流阀。用于限制工作压力。

这些溢流阀 (DB) 主要由带主阀心 (3) 的主阀 (1) 以及带压力调节元件的先导控制阀 (2) 组成。

施加在通道 P 中的压力作用于主阀芯 (3)。同时，该压力通过配有喷嘴 (4) 和 (5) 的控制油路 (6) 和 (7) 施加于主阀芯 (3) 的弹簧负载侧和先导控制阀 (2) 中的滚珠 (8)。如果通道 P 中的压力超过弹簧 (9) 上设定的值，则滚珠 (8) 将背向弹簧 (9) 打开。相应的信号通过控制油路 (10) 和 (6) 从通道 P 由内部传出。此时主阀芯 (3) 弹簧负载侧的液压油通过控制油路 (7)、喷嘴孔 (11) 和滚珠 (8) 流入弹簧腔 (12)。从此处，液压油通过控制油路 (13) 从内部流入油箱（对于型号 DB …），或通过控制油路 (14) 从外部流入油箱（对于型号 DB …Y）。喷嘴 (4) 和 (5) 会导致主阀芯 (3) 出现压降，从而使通道 P 到通道 T 的连接打开。现在，液压油从通道 P 流到通道 T，同时维持设定的工作压力。

溢流阀可通过油口“X”(15) 卸载或切换为另一压力（第二个压力等级）。

减压阀

减压阀是利用液流流过缝隙产生压力损失，使其出口压力低于进口压力的压力控制阀。

按调节要求不同，有定值减压阀，定差减压阀，定比减压阀。

定值减压阀的结构原理

减压阀起减压作用且保证出口压力为定值的条件是:当出口压力大于减压阀的调定压力，使其先导阀开启。

直动式减压阀

减压阀的功用与特点：

减压阀用在液压系统中获得压力低于系统压力的二次油路上

与溢流阀比较:

减压阀是出口压力控制，保证出口压力为定值;溢流阀是进口压力控制，保证进口压力为定值。
