Rexroth力士樂DA 10-1-5X/50-10壓力截止閥

型號(hào) DA…FS…（可自由調(diào)節(jié)的切換壓差）
DA 型壓力閥是一種先導(dǎo)式壓力截止閥。例如，它用于蓄能器充液油路。此時(shí)，蓄能器中將充入液壓油直至達(dá)到蓄能器充液壓力為止。達(dá)到蓄能器壓力后，閥門會(huì)將流量切換到卸壓油路直至液壓系統(tǒng)中的壓降達(dá)到切換壓差為止。然后，再次開始充液過程。
壓力截止閥通常由主殼體 (1)、先導(dǎo)控制閥（2 和 3）、主閥心 (4) 和單向閥 (7) 組成。
將泵流量從 P 至 B 切換為 P 至 T。 ?
泵通過單向閥 (7) 向液壓系統(tǒng)（P 至 A）供油。施加在通道 A 中的壓力通過控制油路 (8) 作用于先導(dǎo)控制閥 (3) 中的控制閥芯。同時(shí)，通道 P 中的壓力通過噴嘴 (5) 施加于主閥芯 (4) 的彈簧負(fù)載側(cè)，并通過控制油路 (9) 作用在擰入式插裝閥 (3) 的入口 (11) 處。當(dāng)在擰入式插裝閥 (3) 中通過調(diào)節(jié)主軸 (12) 設(shè)置的截止壓力到達(dá)液壓系統(tǒng)時(shí)，擰入式插裝閥將打開從主閥芯 (4) 的彈簧負(fù)載側(cè)到回油管路 (10) 再從內(nèi)部進(jìn)入 T（型號(hào) DA ...）的連接或通過油口 Y 從外部進(jìn)入油箱（型號(hào) DA ...Y）的連接。
由于存在噴嘴 (5)，在主閥芯 (4) 處產(chǎn)生了壓降。主閥芯將升離閥座，打開 P 至 T 的連接。單向閥 (7) 將關(guān)閉 P 至 A 的連接。執(zhí)行機(jī)構(gòu)壓力 A 將使擰入式插裝閥 (3) 保持在打開位置。
將泵流量從 P 至 T 切換為 P 至 A。 ?
如果執(zhí)行機(jī)構(gòu)壓力 A 下降至在調(diào)節(jié)主軸 (14) 處設(shè)定的壓力值，則擰入式插裝閥 (3) 將切換到初始位置，并關(guān)閉從主閥芯 (4) 的彈簧負(fù)載側(cè)到回油管路 (10) 的連接。這樣，主閥芯 (4) 彈簧負(fù)載側(cè)的壓力將會(huì)增加，而從 P 到 T 的連接將被壓縮彈簧 (6) 關(guān)閉。泵再次通過單向閥 (7) 向液壓系統(tǒng)，即從 P 到 A 供油。
型號(hào)“FSB07"
此閥的噴嘴位于控制油路 (11) 中，以用于潛在的換向沖擊衰減。這樣，油路壓力（P 至 T）將增加。請(qǐng)參閱特性曲線。
