ATOS2010年總(zong)營業額6千(qian)多萬，主(zhu)要生(sheng)產泵, 閥和系(xi)統，如油(you)缸(gang)伺服(fu)，油(you)缸(gang)，疊(die)加(jia)(jia)閥，閥板。是(shi)常規閥體(ti)企業Y流(liu)的(de)(de)(de)現代化(hua)設備(bei)的(de)(de)(de)工(gong)廠(chang)和先(xian)進的(de)(de)(de)加(jia)(jia)工(gong)技(ji)(ji)(ji)術(shu)手段，Atos是(shi)電(dian)(dian)液技(ji)(ji)(ji)術(shu)方面的(de)(de)(de)專(zhuan)(zhuan)家，全(quan)新產品(pin)設計(ji)和不斷(duan)更新，ATOS所有產品(pin)均(jun)通(tong)(tong)過質量(liang)檢測，擁有專(zhuan)(zhuan)業技(ji)(ji)(ji)術(shu)人員加(jia)(jia)質量(liang)保(bao)證。atos是(shi)的(de)(de)(de)電(dian)(dian)液元(yuan)件(jian)制造商，具(ju)有先(xian)進的(de)(de)(de)技(ji)(ji)(ji)術(shu)，能通(tong)(tong)過帶電(dian)(dian)子器件(jian)的(de)(de)(de)集(ji)成式(shi)液壓元(yuan)件(jian)提高現代化(hua)機器的(de)(de)(de)性能，

電(dian)磁閥(fa)（Electromagnetic valve）是(shi)用(yong)(yong)(yong)電(dian)磁控(kong)制(zhi)的工業設備，是(shi)用(yong)(yong)(yong)來控(kong)制(zhi)流(liu)體的自動(dong)化基(ji)礎(chu)元件，屬(shu)于執行(xing)器，并(bing)不限于液(ye)壓、氣動(dong)。用(yong)(yong)(yong)在工業控(kong)制(zhi)系(xi)統中調(diao)(diao)整(zheng)介(jie)質的方向、流(liu)量、速度和其他的參數。電(dian)磁閥(fa)可(ke)以配合(he)不同(tong)的電(dian)路(lu)來實現預期(qi)的控(kong)制(zhi)，而(er)控(kong)制(zhi)的精(jing)度和靈活性都能夠保證。電(dian)磁閥(fa)有很多種，不同(tong)的電(dian)磁閥(fa)在控(kong)制(zhi)系(xi)統的不同(tong)位置(zhi)發揮作用(yong)(yong)(yong)，醉常用(yong)(yong)(yong)的是(shi)單向閥(fa)、安全(quan)閥(fa)、方向控(kong)制(zhi)閥(fa)、速度調(diao)(diao)節(jie)閥(fa)等。

電(dian)(dian)磁閥里有密(mi)閉的(de)腔，在不(bu)(bu)(bu)同(tong)(tong)(tong)位置(zhi)開有通(tong)孔(kong)，每(mei)個孔(kong)連接不(bu)(bu)(bu)同(tong)(tong)(tong)的(de)油(you)(you)管，腔中間是(shi)活塞(sai)(sai)(sai)(sai)，兩面(mian)(mian)是(shi)兩塊電(dian)(dian)磁鐵(tie)，哪(na)面(mian)(mian)的(de)磁鐵(tie)線圈通(tong)電(dian)(dian)閥體(ti)(ti)就(jiu)(jiu)會(hui)被吸引(yin)到哪(na)邊，通(tong)過控制閥體(ti)(ti)的(de)移動(dong)(dong)來開啟或關閉不(bu)(bu)(bu)同(tong)(tong)(tong)的(de)排油(you)(you)孔(kong)，而進油(you)(you)孔(kong)是(shi)常開的(de)，液壓油(you)(you)就(jiu)(jiu)會(hui)進入不(bu)(bu)(bu)同(tong)(tong)(tong)的(de)排油(you)(you)管，然(ran)后(hou)通(tong)過油(you)(you)的(de)壓力來推動(dong)(dong)油(you)(you)缸的(de)活塞(sai)(sai)(sai)(sai)，活塞(sai)(sai)(sai)(sai)又帶動(dong)(dong)活塞(sai)(sai)(sai)(sai)桿，活塞(sai)(sai)(sai)(sai)桿帶動(dong)(dong)機械裝置(zhi)。這樣通(tong)過控制電(dian)(dian)磁鐵(tie)的(de)電(dian)(dian)流通(tong)斷就(jiu)(jiu)控制了(le)機械運動(dong)(dong)。
