武穴黎翔專業(yè)代理德國(guó)力士樂(lè)全系列產(chǎn)品， 專注原裝全新力士樂(lè) ，假一罰萬(wàn)，力士樂(lè)好價(jià)格！！歡迎詢價(jià)?。?/span>方向控制按用途分為單向閥和換向閥。單向閥：只允許流體在管道中單向接通，反向即切斷。換向閥：改變不同管路間的通、斷關(guān)系。根據(jù)閥芯在閥體中的工作位置數(shù)分兩位、三位等；根據(jù)所控制的通道數(shù)分兩通、三通、四通、五通等；根據(jù)閥芯驅(qū)動(dòng)方式分手動(dòng)，機(jī)動(dòng)，電動(dòng)，液動(dòng)等。圖2為三位四通換向閥的工作原理。P 為供油口，O 為回油口，A 、B 是通向執(zhí)行元件的輸出口。當(dāng)閥芯處?kù)吨形粫r(shí)，全部油口切斷，執(zhí)行元件不動(dòng)；當(dāng)閥芯移到右位時(shí)，P 與A 通，B 與O 通；當(dāng)閥芯移到左位時(shí)，P 與B 通，A 與O 通。這樣，執(zhí)行元件就能作正、反向運(yùn)動(dòng)。
60年代后期，在上述幾種液壓控制閥的基礎(chǔ)上又研制出電液比例控制閥。它的輸出量（壓力、流量）能隨輸入的電信號(hào)連續(xù)變化。電液比例控制閥按作用不同，相應(yīng)地分為電液比例壓力控制閥﹑電液比例流量控制閥和電液比例方向控制閥等。
壓力控制按用途分為溢流閥﹑減壓閥和順序閥。⑴溢流閥：能控制液壓系統(tǒng)在達(dá)到調(diào)定壓力時(shí)保持恒定狀態(tài)。用於過(guò)載保護(hù)的溢流閥稱為安全閥。當(dāng)系統(tǒng)發(fā)生故障，壓力升高到可能造成破壞的限定值時(shí)，閥口會(huì)打開(kāi)而溢流，以保證系統(tǒng)的安全。⑵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）。⑶順序閥：能使一個(gè)執(zhí)行元件（如液壓缸﹑液壓馬達(dá)等）動(dòng)作以后，再按順序使其他執(zhí)行元件動(dòng)作。油泵產(chǎn)生的壓力先推動(dòng)液壓缸1運(yùn)動(dòng)，同時(shí)通過(guò)順序閥的進(jìn)油口作用在面積A 上，當(dāng)液壓缸1運(yùn)動(dòng)完全成后，壓力升高，作用在面積A 的向上推力大於彈簧的調(diào)定值后，閥芯上升使進(jìn)油口與出油口相通，使液壓缸2運(yùn)動(dòng)。

REXROTH力士樂(lè)插裝閥 插裝閥與我們所說(shuō)的普通液壓控制閥有所不同，它的通流量可達(dá)到1000L/min,通徑可達(dá)200～250mm。閥芯結(jié)構(gòu)簡(jiǎn)單，動(dòng)作靈敏，密封性好。它的功能比較單一，主要實(shí)現(xiàn)液路的通或斷，與普通液壓控制閥組合使用時(shí)，才能實(shí)現(xiàn)對(duì)系統(tǒng)油液方向、壓力和流量的控制。

組件由閥芯、閥套、彈簧和密封圈組成。根據(jù)用途不同分為方向閥組件、壓力閥組件和流量閥組件。同一通徑的三種組件安裝尺寸相同，但閥芯的結(jié)構(gòu)形式和閥套座直徑不同。三種組件均有兩個(gè)主油口A 和B、一個(gè)控制口x 。
插裝閥和其閥孔的設(shè)計(jì)通用性的重要性在于大批量生產(chǎn)。
