力士乐安全阀块 Rexroth先导式溢流阀
力士乐安全阀块 Rexroth先导式溢流阀 力士乐DBA/DBAW型泵安全块是集成到油路块中的先导式溢流阀, 可直接安装在泵的 SAE 压力油口上。 它们用于限制工作压力(DBA),或限制并以磁力卸载工作压 (DBAW)。 Rexroth泵安全块(DBA)主要由阀组,主阀心和带调整类型的, 用于压力调节的先导控制阀组成。
力士乐安全阀块 Rexroth先导式溢流阀详细介绍

力士乐泵安全阀块,Rexroth先导式溢流阀,力士乐DBA/DBAW型安全阀块(溢流阀)的特点: 泵的0压启动和油路;直接安装在泵的SAE压力油口上;快速压力增大;用于调节压力的4种调节类型,可选:旋钮、六角螺钉和保护帽、带刻度可锁定旋钮、带刻度旋钮;5 个压力等级,可选; 通过附带方向阀的电磁线圈操作卸载;集成的单向阀,可选;换向冲击衰减,可选(仅型号 DBAW)

力士乐DBA/DBAW型泵安全块是集成到油路块中的先导式溢流阀,  可直接安装在泵的 SAE 压力油口上。  它们用于限制工作压力(DBA),或限制并以磁力卸载工作压 (DBAW)。  泵安全块(DBA)主要由阀组(1),主阀心(3)和带调整类型的,  用于压力调节的先导控制阀(2)组成。阀体具有油口 P(用于液压油  的输入)和油口 P1(用于输出)。这两个油口之间的通孔的支路中有  主阀心。该主阀心打开时,出现到油口 T 的连接 (油箱管路)。力士乐安全阀块 Rexroth先导式溢流阀  

Rexroth泵安全块型号 DBA  施加于通孔中的压力作用于主阀芯(3)。同时,该压力通过带有  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,同时施加于先导控制阀(2)中的滚珠(8)。   如果通孔中的压力超过弹簧(9)上设定的值,则滚珠(8)背向  弹簧(9)打开。  通过控制油路(10)和(6)从通孔内部地提供此过程的信号。   此时主阀芯(3)的弹簧负载侧上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 DBA),或通过  控制油路(14)从外部流入油箱(对于型号 DBA … Y)。   喷嘴 (4)和(5)可导致主阀芯(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,   从而维持设定的工作压力保持不变。  油口(15)可用于遥控。如果要在此处连接压力负载单元或压力  表隔离阀,则必须订购型号 SO616(没有喷嘴(4))。这样可  防止在操作压力表隔离阀时出现建压延迟或短时压降。  

力士乐安全阀块 Rexroth先导式溢流阀 力士乐泵安全块型号 DBAR(带单向阀)  集成单向阀可在泵断开连接的情况下维持系统压力,并防止液压  油流回泵中。  选择此阀即可满足对于单向阀的需求,无需其它的单向阀。

此外,可通过控制附带方向阀(16)将其从压力限制功能切换至 0 压油路。因此,泵可以进行 0 压启动。带换向冲击衰减(叠加阀板)有泵安全块,  型号 DBAW…S6E...R12 和型号 DBAW…S6SM...B12  通过换向冲击衰减阀(17)可延迟打开从 B2 到 B1 或从 P2 到   P1 的连接,从而避免了回油管路中的压力峰值和减压冲击噪音。该阀安装在先导控制阀(2)和方向阀(16)之间。  衰减程度(降压冲击)取决于喷嘴(18)的规格。默认情况下,  安装喷嘴 Ø1.2 mm(订货代码 ..R12.. 或 ..B12..)。
