ATOS阿托斯溢流閥的工作原理及分類：

定壓溢流作用：在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當系統(tǒng)壓力增大時，會使流量需求減小。此時溢流閥開啟，使多余流量溢回油箱，保證溢流閥進口壓力，即泵出口壓力恒定（閥口常隨壓力波動開啟）。

安全保護作用：系統(tǒng)正常工作時，閥門關(guān)閉。只有負載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時開啟溢流，進行過載保護，使系統(tǒng)壓力不再增加（通常使溢流閥的調(diào)定壓力比系統(tǒng)zui高工作壓力高10％～20％）。

作卸荷閥用

作遠程調(diào)壓閥

作高低壓多級控制閥

作順序閥

用于產(chǎn)生背壓（串在回油路上）。

錐閥式直動型溢流閥：錐閥2的左端設(shè)有偏流盤1托住彈壓彈簧5，錐閥右端有一阻尼活塞3（阻尼活塞一方面在錐閥開啟或閉合時起阻尼作用，用來提高錐閥工作的穩(wěn)定性；另一方面用來保證錐閥開啟后不會傾斜）。進口的壓力油（壓力為P）可以由此活塞的徑向間隙進入活塞底部，形成一個向左的液壓力F=P·A（A為活塞底部面積）。當作用在底部的液壓力F大于彈簧力時，錐閥閥口打開，油液由錐閥口經(jīng)回流口溢回油箱。只要閥口打開，有油液流經(jīng)溢流閥，溢流閥入口的壓力就基本保持恒定。通過調(diào)節(jié)桿4來改變調(diào)壓彈簧5的預緊力Ft，即可調(diào)整溢流壓力。
