VICKERS電(dian)(dian)磁(ci)換(huan)向(xiang)閥(fa)(fa)在大家(jia)的(de)生產(chan)制(zhi)造(zao)中運(yun)用(yong)十分(fen)普(pu)遍,相信大家(jia)對電(dian)(dian)磁(ci)閥(fa)(fa)都有一(yi)個基本的(de)了解(jie),電(dian)(dian)磁(ci)閥(fa)(fa)是(shi)由磁(ci)鐵線圈(quan)和(he)磁(ci)心(xin)構成,是(shi)包括(kuo)一(yi)個或(huo)(huo)(huo)好多個孔的(de)閥(fa)(fa)體(ti)(ti)。當電(dian)(dian)磁(ci)線圈(quan)插電(dian)(dian)或(huo)(huo)(huo)關閉電(dian)(dian)源時,磁(ci)心(xin)的(de)運(yun)行將造(zao)成液體(ti)(ti)根據閥(fa)(fa)體(ti)(ti)或(huo)(huo)(huo)被斷開(kai),以做到更改液體(ti)(ti)方位的(de)目的(de)。
電(dian)磁(ci)閥(fa)(fa)內(nei)部有(you)一個密封性內(nei)腔,在不(bu)(bu)一樣部位開有(you)通(tong)孔(kong),每一個孔(kong)通(tong)往(wang)不(bu)(bu)一樣的輸油(you)(you)管,內(nei)腔正中間是閘閥(fa)(fa),兩邊有(you)兩個電(dian)磁(ci)閥(fa)(fa)。當磁(ci)鐵線圈插電(dian)時,閥(fa)(fa)會(hui)被(bei)吸到(dao)對(dui)應方(fang)向,根據(ju)操(cao)縱閥(fa)(fa)的運(yun)動來(lai)阻塞或(huo)泄露不(bu)(bu)一樣的排進油(you)(you)口,而進油(you)(you)口一直(zhi)開啟的,因(yin)此齒輪油(you)(you)會(hui)進到(dao)不(bu)(bu)一樣的排輸油(you)(you)管。油(you)(you)壓(ya)促(cu)進液(ye)(ye)(ye)壓(ya)缸(gang)(gang)活塞桿(gan),液(ye)(ye)(ye)壓(ya)缸(gang)(gang)活塞桿(gan)又推動液(ye)(ye)(ye)壓(ya)缸(gang)(gang),液(ye)(ye)(ye)壓(ya)缸(gang)(gang)推動機(ji)械(xie)設備(bei)。那樣,根據(ju)操(cao)縱電(dian)磁(ci)閥(fa)(fa)的電(dian)流(liu)量來(lai)操(cao)縱設備(bei)運(yun)行。
