力士樂DBA/DBAW型安全閥塊（溢流閥）的特點： 泵的0壓啟動和油路；直接安裝在泵的SAE壓力油口上；快速壓力增大；用于調(diào)節(jié)壓力的4種調(diào)節(jié)類型，可選：旋鈕、六角螺釘和保護帽、帶刻度可鎖定旋鈕、帶刻度旋鈕；5 個壓力等級，可選； 通過附帶方向閥的電磁線圈操作卸載；集成的單向閥，可選；換向沖擊衰減，可選（僅型號 DBAW）
力士樂DBA/DBAW型泵安全塊是集成到油路塊中的先導(dǎo)式溢流閥， 可直接安裝在泵的 SAE 壓力油口上。 它們用于限制工作壓力（DBA），或限制并以磁力卸載工作壓 （DBAW）。 泵安全塊（DBA）主要由閥組（1），主閥心（3）和帶調(diào)整類型的， 用于壓力調(diào)節(jié)的先導(dǎo)控制閥（2）組成。閥體具有油口 P（用于液壓油 的輸入）和油口 P1（用于輸出）。這兩個油口之間的通孔的支路中有 主閥心。該主閥心打開時，出現(xiàn)到油口 T 的連接 （油箱管路）。
Rexroth泵安全塊型號DBA 施加于通孔中的壓力作用于主閥芯（3）。同時，該壓力通過帶有 噴嘴（4）和（5）的控制油路（6）和（7）施加于主閥芯（3） 的彈簧負載側(cè)，同時施加于先導(dǎo)控制閥（2）中的滾珠（8）。 如果通孔中的壓力超過彈簧（9）上設(shè)定的值，則滾珠（8）背向 彈簧（9）打開。 通過控制油路（10）和（6）從通孔內(nèi)部地提供此過程的信號。 此時主閥芯（3）的彈簧負載側(cè)上的液壓油通過控制油路（7）， 噴嘴孔（11）和滾珠（8）流入彈簧腔（12）。從此處，液壓油 通過控制油路（13）從內(nèi)部流入油箱（對于型號 DBA），或通過 控制油路（14）從外部流入油箱（對于型號 DBA … Y）。 噴嘴 （4）和（5）可導(dǎo)致主閥芯（3）出現(xiàn)壓降，從而使通道 P 到通道 T 的連接打開?，F(xiàn)在，液壓油從通道 P 流到通道 T， 從而維持設(shè)定的工作壓力保持不變。 油口（15）可用于遙控。如果要在此處連接壓力負載單元或壓力 表隔離閥，則必須訂購型號 SO616（沒有噴嘴（4））。這樣可 防止在操作壓力表隔離閥時出現(xiàn)建壓延遲或短時壓降。
力士樂泵安全塊型號DBAR（帶單向閥） 集成單向閥可在泵斷開連接的情況下維持系統(tǒng)壓力，并防止液壓 油流回泵中。 選擇此閥即可滿足對于單向閥的需求，無需其它的單向閥。
力士樂泵安全塊型號 DBAW...
此外，可通過控制附帶方向閥（16）將其從壓力限制功能切換至 0 壓油路。因此，泵可以進行 0 壓啟動。帶換向沖擊衰減（疊加閥板）有泵安全塊， 型號 DBAW…S6E...R12 和型號 DBAW…S6SM...B12 通過換向沖擊衰減閥（17）可延遲打開從 B2 到 B1 或從 P2 到 P1 的連接，從而避免了回油管路中的壓力峰值和減壓沖擊噪音。該閥安裝在先導(dǎo)控制閥（2）和方向閥（16）之間。 衰減程度（降壓沖擊）取決于噴嘴（18）的規(guī)格。默認情況下， 安裝噴嘴 Ø1.2 mm（訂貨代碼 ..R12.. 或 ..B12..）。
