Rexroth帶直流電機(jī)操作減壓閥
【產(chǎn)品簡(jiǎn)介】
【詳細(xì)說明】
力士樂DRG型壓力控制閥為先導(dǎo)式減壓閥。 它們用于降低系統(tǒng)壓力。Rexroth帶直流電機(jī)操作減壓閥DRG系列基本上由帶電動(dòng)機(jī)的先導(dǎo)閥(電動(dòng)機(jī)作為壓力 調(diào)節(jié)元件),帶主閥心的主閥和可選單向閥組成。 A 中減小的壓力通過帶減速齒輪(17)的直流電機(jī)(16)進(jìn)行調(diào)節(jié)。減速齒輪(17)的輸出軸旋轉(zhuǎn)凸輪(15),便會(huì)通過彈簧座(9)更改彈簧(5)的張力,從而導(dǎo)致壓力的變化。油口 A 中為減小的壓力,油口 B 中為入口壓力。主液體流從B 流向 A。 實(shí)際值電位計(jì)(18)可反饋凸輪(15)的位置??蛇x擇安裝電氣限位開關(guān)來代替實(shí)際值電位計(jì)(18),用于限制zui小和zui大壓力。 對(duì)于帶限位開關(guān)的型號(hào),壓力范圍從 pmin 到 pmax 的zui小調(diào)節(jié)時(shí)間為 18 秒。 18 秒調(diào)節(jié)時(shí)間可實(shí)現(xiàn)以點(diǎn)動(dòng)模式逐漸達(dá)到所需的壓力。對(duì)于帶實(shí)際值電位計(jì)的型號(hào),壓力范圍從pmin到pmax的zui小調(diào)節(jié)時(shí)間為1.3 秒。與相關(guān)放大器類型 VT-VRM1-1 配合使用,可實(shí)現(xiàn)程序控制。借助 2 個(gè)附加壓力開關(guān),可限制zui小和zui大壓力。 對(duì)于帶限位開關(guān)的型號(hào),出現(xiàn)電源故障(電纜斷連,保險(xiǎn) 絲故障,短路等)時(shí),將會(huì)保持閥的壓力設(shè)置。
力士樂DRG型先導(dǎo)式減壓閥規(guī)格8和10:A 中減小的壓力通過節(jié)流孔(2.1),先導(dǎo)管路(4), 節(jié)流孔(2.2)和節(jié)流孔(3),同時(shí)施加于主閥芯(1)的彈簧負(fù)載側(cè)。 主閥芯(1)彈簧負(fù)載側(cè)上的壓力是因壓縮彈簧(10.2)的壓差低于 A 中的壓力而產(chǎn)生的。壓縮彈簧(10.2)沿 開口方向作用于主閥芯(1)。根據(jù)節(jié)流孔(2.1;2.2)的開口剖面和壓縮彈簧(10.2)的壓差,先導(dǎo)油經(jīng)過節(jié)流孔 (2.1),先導(dǎo)管路(4),節(jié)流孔(2.2),閥心(6)流入彈簧腔(7),并通過帶底板安裝型號(hào)的 Y(12.2)或 帶螺紋連接型號(hào)的(12.1)進(jìn)一步流向油箱。 當(dāng) A 中的壓力上升到高于先導(dǎo)閥(11)上的設(shè)置值時(shí),主閥 芯(1)將減小從 B 到 A 的流動(dòng)剖面,直到油口 A 中再次達(dá)到先導(dǎo)閥(11)上設(shè)置的壓力。相反,當(dāng) A 中的壓力低于先 導(dǎo)閥(11)上的設(shè)置值時(shí),主閥芯(1)將增大從 B 到 A的流動(dòng)剖面。當(dāng) A 和執(zhí)行機(jī)構(gòu)之間有靜態(tài)油柱時(shí),只有先導(dǎo)油通過主閥芯 從 B 流向 A。 在這個(gè)位置,如果先導(dǎo)閥(11)上設(shè)置了較低的壓力,主閥 芯(1)將會(huì)中斷從 B 到 A 的先導(dǎo)供油,直到 A 和執(zhí)行機(jī)構(gòu) 之間隔離的油柱已通過節(jié)流孔(2.1),先導(dǎo)管路(4), 節(jié)流孔(2.2),閥心(6)和油口 Y 擴(kuò)展到先導(dǎo)閥(11) 上的較低壓力。 可選擇安裝單向閥(14)以允許從 A 到 B 的自由回流。
力士樂DRG型規(guī)格16至32 與 DRG 8 和 DRG 10 不同,對(duì)于這些閥,先導(dǎo)油從入口壓力 通道 B 獲得。流量調(diào)節(jié)器(13)使先導(dǎo)油流量保持恒定。 如果 A 和執(zhí)行機(jī)構(gòu)之間有靜態(tài)油柱,先導(dǎo)閥(11)上設(shè)置 了較低的壓力,那么油柱將會(huì)通過單向閥(10.1),先導(dǎo)管 路 (4),閥心(6)和油口 Y 卸載。
