力士樂(le)M-3SEW電(dian)磁閥(fa)(fa)(fa)概(gai)述(shu)：     力士樂(le)M-SEW型(xing)方向閥(fa)(fa)(fa)是(shi)電(dian)磁截止(zhi)式方向閥(fa)(fa)(fa)，用(yong)於控制油液的流動、停止(zhi)和方向。力士樂(le)M-SEW 型(xing)方向閥(fa)(fa)(fa)其組成主(zhu)要包括閥(fa)(fa)(fa)體 (1)、電(dian)磁鐵 (2)，經過硬化處理的閥(fa)(fa)(fa)系統(tong) (3)，以(yi)及(ji)作為關(guan)閉件的球 (4)。

力(li)士(shi)樂(le)M-SEW 型(xing)方(fang)向(xiang)閥(fa)基本原理：     在(zai)初始位置，閥(fa)芯(xin) (4) 被彈簧 (9) 推向(xiang)閥(fa)座，在(zai)切換位置，電(dian)磁(ci)(ci)鐵(tie) (2) 將(jiang)其推向(xiang)閥(fa)座。電(dian)磁(ci)(ci)鐵(tie) (2) 的(de)力(li)經過角狀杠桿(gan) (6) 和(he)球 (7) 作用於兩(liang)面密封的(de)操(cao)作推桿(gan) (8)。 在(zai)兩(liang)個密封元件之間的(de)閥(fa)腔與P口連(lian)通。這樣，閥(fa)系(xi)統 (3) 的(de)壓(ya)力(li)相對於操(cao)作力(li) (電(dian)磁(ci)(ci)鐵(tie)或彈簧)，處於平衡狀態 (即推桿(gan)、閥(fa)芯(xin)軸系(xi)處於軸向(xiang)液(ye)壓(ya)力(li)平衡狀態)。這種(zhong)閥(fa)因此可在(zai)壓(ya)力(li)高達 630bar 條件下使用。

力(li)士(shi)樂(le)(le)M-SEW型方(fang)向閥(fa)選型需(xu)要(yao)哪些參數呢(ni)？    德國力(li)士(shi)樂(le)(le)M-3SEW電(dian)磁閥(fa)資料     力(li)士(shi)樂(le)(le)M-3SEW電(dian)磁閥(fa)在2位3通(tong)方(fang)向提升閥(fa)的(de)下方(fang)連接一個迭加(jia)板，即附加(jia)-1板，力(li)士(shi)樂(le)(le)M-3SEW電(dian)磁閥(fa)可用作2位4通(tong)截止式方(fang)向閥(fa)。在使用過程(cheng)中力(li)士(shi)樂(le)(le)M-3SEW電(dian)磁閥(fa)的(de)運行過程(cheng)是怎(zen)么樣的(de)呢(ni)？

力士樂M-3SEW電磁閥初始位置(zhi)：     主(zhu)閥沒(mei)有(you)運作。彈簧 (9) 使閥芯 (4.1) 保持在閥座(zuo)  (11)上。油(you)(you)(you)口P關(guan)閉，油(you)(you)(you)口A與(yu)油(you)(you)(you)口T相連(lian)通(tong)。此外(wai)，從A到控(kong)制(zhi)活(huo)塞(12) 的大(da)面積上有(you)一條控(kong)制(zhi)管路，可向油(you)(you)(you)箱卸荷。經(jing)過(guo)油(you)(you)(you)口P產生的壓力這時(shi)將球 (13) 推(tui)向閥座(zuo) (14)。所以(yi)油(you)(you)(you)口P與(yu)油(you)(you)(you)口B 連(lian)通(tong)，A 和(he) T 連(lian)通(tong)。

力(li)士樂M-3SEW電磁(ci)閥過(guo)渡(du)位置：     當主閥工(gong)作(zuo)時，球 (4.2) 被推動而(er)克服彈(dan)簧(huang)力(li) (9)，然(ran)後壓在閥座 (15) 上。
