ZDB6VP2-4X/315V力士乐溢流阀

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。

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。

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）。

顺序阀

顺序阀是一种利用压力控制阀口通断的压力阀。

按控制油来源不同分内控和外控，按弹簧腔泄漏油引出方式不同分内泄和外泄。

顺序阀的四种控制方式

通过改变上盖或底盖的装配位置可得到内控外泄、内控内泄、外控外泄、外控内泄四种类型。

内控外泄顺序阀

内控外泄顺序阀与溢流阀非常相象:阀口常闭，进口压力控制，但是该

阀出口油液要去工作，所以有单独的泄油口。

内控外泄顺序阀用于多个执行元件顺序动作。其进口压力先要达到阀的调定压力，而出口压力取决于负载。当负载压力高于阀的调定压力时，进口压力等于出口压力，阀口全开;当负载压力低于调定压力时，进口压力等于调定压力，阀的开口一定。
