简要说明：上海啸力液压牌的先导溢流阀DBW10B-1-50B/315运行稳定/使用寿命长产品：估价：1，规格：完善，产品系列编号：齐全

DB型阀是先导控制式的溢流阀，DBW型阀是先导控制式的电磁溢流阀。DB型阀是用来控制液压系统的压力，DBW型阀也可以控制液压系统的压力，并且能在任意时刻使系统卸荷.本阀是由电磁阀，先导阀和主阀组成，导阀和主阀均为锥阀式结构，并采用了铸造内流道，流通能力强，流量大，启闭性能好。广泛应用于航天，轻工，冶金，矿山等各领域机床机械。

DB型溢流阀 油路A中的压力作用于主阀芯(3)上。同时，压力经带节流孔(4)和(5)的控制通路(6)和(7)作用在主阀芯(3)的弹簧加载侧及先导阀(2)的球(8)上。如果通路A中的压力超过弹簧(9)的设定值，球(8)克服弹簧(9)开启。对此该信号由控制线(10)和(6)从A通路内部供给。主阀芯(3)弹簧加载侧的油液经过控制通路(7)、节流(11)和球阀(8)流入弹簧腔(12)。从这里内部供给 —DB—5X 型，由控制通路(13)，或外部供给—DB..—5X..Y—型，由控制通路(14)引入油箱。节流孔(4)和(5)在主阀芯(3)产生压降，有A管至B连接口打开。油液由A管流向B管，而设定工作压力保持不变。溢流阀借助油口X(15)可对不同压力(第二个压力额定值)卸荷或切换。 DBW型溢流阀 原则上，该阀功能与DB型阀相同。借助于安装于其上的方向阀(16)的动作主阀芯(3)可实现卸荷。
