力士樂液壓閥簡介：
力士樂液壓閥（簡稱液壓閥）在液壓系統(tǒng)中的功用是通過控制調(diào)節(jié)液壓系統(tǒng)中油液的流向、壓力和流量，使執(zhí)行器及其驅(qū)動的工作機構(gòu)獲得所需的運動方向、推力（轉(zhuǎn)矩）及運動速度（轉(zhuǎn)速）等。任何一個液壓系統(tǒng)，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(jié)構(gòu)截然不同的多種液壓系統(tǒng)方案。因此，液壓閥是液壓技術(shù)中品種與規(guī)格多、應用泛、的部分（元件）；一個新設計或正在運轉(zhuǎn)的液壓系統(tǒng)，能否按照既定要求正?？煽康剡\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(yōu)劣及參數(shù)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(tǒng)在達到調(diào)定壓力時保持恒定狀態(tài)。用于過載保護的溢流閥稱為安全閥。當系統(tǒng)發(fā)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(tǒng)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(wěn)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(zhí)行元件（如液壓缸、液壓馬達等）動作以后,再按順序使其他執(zhí)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(nèi)的油倒流入噴油泵內(nèi)。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(huán)帶，其作用是在供油終了時，使高壓油管內(nèi)的油壓迅速下降，避免噴孔處產(chǎn)生滴油現(xiàn)象。當環(huán)帶落入閥座內(nèi)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(zhuǎn)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(chǎn)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(nèi)的柴油經(jīng)油孔進入泵油室，柱塞運動到下止點，進油結(jié)束。供油過程當凸輪軸轉(zhuǎn)到凸輪的凸起部分頂起滾[工業(yè)電器網(wǎng)-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(jīng)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?。?.0015-0.0025mm）使柱塞頂部的泵油室成為一個密封油腔，柱塞繼續(xù)上升，泵油室內(nèi)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(jīng)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。
