DBD型溢流阀是直动式溢流阀。它们用于xian制系统压力。该阀组成主要包括阀套（1）、弹簧（2）、带缓冲滑阀的锥阀芯（3）。（压力等级25至400bar）或球阀芯（4）（压力等级630bar）和压力调节元件（5），借助于该调节元件（5）可设定系统压力。弹簧（2）将锥阀芯（3）压在其阀座上，管路P和系统连接，系统压力作用在提升阀锥（或球）阀芯面积上。
如果管路中P的压力超过弹簧（2）的设定值，则提升阀锥阀芯（3）或者球阀芯（4）客服弹簧力（2）而开启。压力油从P管路流向T管路，提升阀阀芯（3）的行程受销轴（6）的xian制。为在整个压力范围内获得准确的设力设定值，压力范围划分为7种压力等级，每种压力等级对应一个可设定响应zui高压力的弹簧。
