DBDS10P1A/315直动式溢流阀

溢流阀一般有两种结构：1、直动型溢流阀 。2、先导式溢流阀。

对溢流阀的主要要求：调压范围大，调压偏差小，压力振摆小，动作灵敏，过载能力大，噪声小。

先导型溢流阀的导阀部分结构尺寸较小，调压弹簧不必很强，因此压力调整比较轻便。但因先导型溢流阀要在先导阀和主阀都动作后才能起控制作用，因此反应不如直动型溢流阀灵敏。

与三节同心结构相比，二节同心结构的特点是：①主阀芯仅与阀套和主阀座有同心度要求，免去了与阀盖的配合，故结构简单，加工和装配方便。②过流面积大，在相同流量的情况下，主阀开启高度小；或者在相同开启高度的情况下，其通流能力大，因此，可做得体积小、重量轻。③主阀芯与阀套可以通用化，便于批量生产。

溢流阀是一种液压压力控制阀，在液压设备中主要起定压溢流，稳压，系统卸荷和安全保护作用。溢流阀在装配或使用中，由于O形密封圈、组合密封圈的损坏，或者安装螺钉、管接头的松动，都可能造成不应有的外泄漏。如果锥阀或主阀芯磨损过大，或者密封面接触不良，还将造成内泄漏过大，甚至影响正常工作。

定压溢流作用：在定量泵节流调节系统中，定量泵提供的是恒定流量。当系统压力加大时，会使流量需求减小。此时溢流阀开启，使多余流量溢回油箱，保证溢流阀进口压力，即泵出口压力恒定（阀口常随压力波动开启）。

稳压作用：溢流阀串联在回油路上，溢流阀产生背压，运动部件平稳性增加。

系统卸荷作用：在溢流阀的遥控口串接溢小流量的电磁阀，当电磁铁通电时，溢流阀的遥控口通油箱，此时液压泵卸荷。溢流阀此时作为卸荷阀使用。

安全保护作用：系统正常工作时，阀门关闭。只有负载超过规定的极限（系统压力超过调定压力）时开启溢流，进行过载保护，使系统压力不再增加（通常使溢流阀的调定压力比系统较高工作压力高10%～20%）。

DBDS10P1A/315直动式溢流阀

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）。

减压阀是通过调节，将进口压力减至某一需要的出口压力，并依靠介质本身的能量，使出口压力自动保持稳定的阀门。从流体力学的观点看，减压阀是一个局部阻力可以变化的节流元件，即通过改变节流面积，使流速及流体的动能改变，造成不同的压力损失，从而达到减压的目的。然后依靠控制与调节系统的调节，使阀后压力的波动与弹簧力相平衡，使阀后压力在一定的误差范围内保持恒定。
