DBD 型溢流閥是一種直動(dòng)式座閥。這些閥用于限制系統(tǒng)壓力。

這些閥門主要由下列組件組成：套筒、彈簧、帶有衰減柱塞的閥心（壓力等級(jí) 25 bar … 400 bar）或滾珠（壓力等級(jí) 630 bar）及調(diào)整類型�？墒褂谜{(diào)整類型 對(duì)系統(tǒng)壓力進(jìn)行無(wú)級(jí)調(diào)節(jié)。彈簧將閥心或滾珠推到閥座上。通道P連接到系統(tǒng)。系統(tǒng)中存在的壓力將作用于閥心表面（或滾珠）。如果通道P中的壓力超過彈簧 上設(shè)定的值，則閥心或滾珠背向彈簧 打開。此時(shí)，液壓油從通道P流入通道T。閥心的行程受壓花的限制。

為了在整個(gè)壓力范圍內(nèi)實(shí)現(xiàn)良好的壓力調(diào)節(jié)，整個(gè)壓力范圍已被分成了 7 個(gè)壓力等級(jí)。一個(gè)壓力等級(jí)對(duì)應(yīng)于一個(gè)特定彈簧可設(shè)定的大工作壓力。

注意：

調(diào)整類型 經(jīng)過特別建構(gòu)，可防止其丟失。得益于萬(wàn)向架的設(shè)計(jì)，調(diào)整類型 中的調(diào)節(jié)元件在完全卸載后會(huì)保持松動(dòng)（可移動(dòng)）狀態(tài)。

壓力等級(jí)“25”：盡管調(diào)整類型處于完全卸載狀態(tài)，但若未確定小壓力，則調(diào)節(jié)元件仍會(huì)在較小的彈簧力和/或回復(fù)力作用下“回到”停止?fàn)顟B(tài)。

在經(jīng)過壓力調(diào)節(jié)/提升后，可將調(diào)節(jié)元件再次擰入。
