DB20-1-5X/50YU先导式溢流阀

溢流阀

类型:直动式、先导式

作用:

(1)在不断溢流过程中保持系统压力恒定，起稳压和溢流作用(p,FP

系统’阀口常开) ;

(2)防止液压系统过载，起安全保护作用(p,=1.1~1.2p,max，阀口常闭)

(一)溢流阀的基本结构及其工作原理

1、直动式溢流阀

工作原理:

直接利用液压力与弹簧力相平衡以控制阀芯的启闭动作，从而保证进油口压力基本恒定。

特点:

①阀芯所受的液压力全靠弹簧力平衡，故当系统压力很高时，弹簧必须很硬，导致结构笨重，调压不轻便。一般用于压力小于2.5MPa的低压系统中，作安全阀或背压阀使用。

②由于惯性或负载的变化，导致q、变化，即开口度h的变化，由于k很大，所以p不稳定，稳压精度差;

③结构简单、便宜，但工作时易产生振动和噪音。

先导型溢流阀

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。

先导型溢流阀遥控口接法

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。

DB20-1-5X/50YU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）。

CRQ型阀是一种插装式先导压力控制阀，它可以安装在具有D-10C阀座孔的集成块式阀板上。型底座上。该阀通常用于控制液压阀的压力，在压力接近设定值时，仍然可以使泵在满流量下工作。该阀提供四种压力调整范围，大压力 350 bar。该阀由平衡型主阀和一个先导阀组成。主阀通常处于封闭状态，当回路压力超过由先导阀设定的值时，主阀打开，油液通过 T 口直接回油箱。可用调整螺钉改变设定压力，通常用内六角螺钉，同时装有锁紧螺母和大调节限位器。
