      力士樂液壓閥簡介:
      力士樂液壓閥(簡稱液壓閥)在液壓系統中的功用是通過控制調節液壓系統中油液的流向、壓力和流量,使執行器及其驅動的工作機構獲得所需的運動方向、推力(轉矩)及運動速度(轉速)等。任何一個液壓系統,不論其如何簡單,都不能缺少液壓閥;同一工藝目的的液壓機械設備,通過液壓閥的不同組合使用,可以組成油路結構截然不同的多種液壓系統方案。因此,液壓閥是液壓技術中品種與規格多、應用泛、的部分(元件);一個新設計或正在運轉的液壓系統,能否按照既定要求正常可靠地運行,在很大程度上取決于其中所采用的各種液壓閥的性能優劣及參數匹配是否合理 [1]  。
      壓力控制閥
      按用途分為溢流閥、減壓閥和順序閥。①溢流閥:能


      力士樂液壓閥
      控制液壓系統在達到調定壓力時保持恒定狀態。用于過載保護的溢流閥稱為安全閥。當系統發生故障,壓力升高到可能造成破壞的限定值時,閥口會打開而溢流,以保證系統的安全。②減壓閥:能控制分支回路得到比主回路油壓低的穩定壓力。減壓閥按它所控制的壓力功能不同,又可分為定值減壓閥(輸出壓力為恒定值)、定差減壓閥(輸入與輸出壓力差為定值)和定比減壓閥(輸入與輸出壓力間保持一定的比例)。③順序閥:能使一個執行元件(如液壓缸、液壓馬達等)動作以后,再按順序使其他執行元件動作 [2]  。

       

      力士樂液壓閥安裝方法:
      出油閥是一個單向閥,在彈簧壓力作用下,閥上部圓錐面與閥座嚴密配合,其作用是在停供時,將高壓油管與柱塞上端空腔隔絕,防止高壓油管內的油倒流入噴油泵內。出油閥的下部呈十字斷面,既能導向,又能通過柴油。出油閥的錐面下有一個小的圓柱面,稱為減壓環帶,其作用是在供油終了時,使高壓油管內的油壓迅速下降,避免噴孔處產生滴油現象。當環帶落入閥座內時則使上方容積很快增大,壓力迅速減小,停噴迅速。力士樂液壓閥工作時,在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下,迫使柱塞作上、下往復運動,從而完成泵油任務,泵油過程可分為以下三個階段。進油過程當凸輪的凸起部分轉過去后,在彈簧力的作用下,柱塞向下運動,柱塞上部空間(稱為泵油室)產生真空度,當柱塞上端面把柱塞套上的進油孔打開后,充滿在油泵上體油道內的柴油經油孔進入泵油室,柱塞運動到下止點,進油結束。供油過程當凸輪軸轉到凸輪的凸起部分頂起滾[工業電器網-cnelc]輪體時,柱塞彈簧被壓縮,柱塞向上運動,燃油受壓,一部分燃油經油孔流回噴油泵上體油腔。當柱塞頂面遮住套筒上進油孔的上緣時,由于柱塞和套筒的配合間隙很小(0.0015-0.0025mm)使柱塞頂部的泵油室成為一個密封油腔,柱塞繼續上升,泵油室內的油壓迅速升高,泵油壓力出油閥彈簧力+高壓油管剩余壓力時,推開出油閥,高壓柴油經出油閥進入高壓油管,通過噴油器噴入燃燒室。REXROTH柱塞泵上供油,當上行到柱塞上的斜槽(停供邊)與套筒上的回油孔相通時,泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通,油壓驟然下降,出油閥在彈簧力的作用下迅速關閉,停止供油。
