防腐蚀设计

DBD 型溢流阀是一种直动式座阀。这些阀用于限制系统压力。

这些阀门主要由下列组件组成：套筒 (1)、弹簧 (2)、带有衰减柱塞的阀心 (3)（压力等级 25 bar … 400 bar）或滚珠 (4)（压力等级 630 bar）及调整类型 (5)。

可使用调整类型 (5) 对系统压力进行无级调节。弹簧 (2) 将阀心 (3) 或滚珠 (4) 推到阀座上。通道 P 连接到系统。系统中存在的压力将作用于阀心表面（或滚珠）。

如果通道 P 中的压力超过弹簧 (2) 上设定的值，则阀心 (3) 或滚珠 (4) 背向弹簧 (2) 打开。此时，液压油从通道 P 流入通道 T。阀心 (3) 的行程受压花 (6) 的限制。

为了在整个压力范围内实现良好的压力调节，整个压力范围已被分成了 7 个压力等级。一个压力等级对应于一个特定弹簧可设定的最大工作压力。

注意：

调整类型 (5) 经过特别建构，可防止其丢失。得益于万向架的设计，调整类型 (5) 中的调节元件在完全卸载后会保持松动（可移动）状态。

压力等级“25”：尽管调整类型处于完全卸载状态，但若未确定最小压力，则调节元件仍会在较小的弹簧力和/或回复力作用下“回到”停止状态。

在经过压力调节/提升后，可将调节元件再次拧入。
