阿托斯ATOS換(huan)向(xiang)(xiang)(xiang)閥(fa)(fa)是(shi)具有兩(liang)種(zhong)以上(shang)流動(dong)(dong)(dong)形(xing)式(shi)(shi)和(he)兩(liang)個以上(shang)油口的(de)(de)方(fang)(fang)向(xiang)(xiang)(xiang)控制(zhi)(zhi)(zhi)閥(fa)(fa)。是(shi)實現液(ye)(ye)壓油流的(de)(de)溝通、切斷和(he)換(huan)向(xiang)(xiang)(xiang)，以及壓力卸載(zai)和(he)順序(xu)動(dong)(dong)(dong)作(zuo)控制(zhi)(zhi)(zhi)的(de)(de)閥(fa)(fa)門。靠閥(fa)(fa)芯與(yu)(yu)閥(fa)(fa)體的(de)(de)相(xiang)對運動(dong)(dong)(dong)的(de)(de)方(fang)(fang)向(xiang)(xiang)(xiang)控制(zhi)(zhi)(zhi)閥(fa)(fa)。有轉 閥(fa)(fa)式(shi)(shi)和(he)滑(hua)閥(fa)(fa)式(shi)(shi)兩(liang)種(zhong)。按閥(fa)(fa)芯在閥(fa)(fa)體內停留的(de)(de)工作(zuo)位(wei) 置數分為(wei)二位(wei)、三(san)位(wei)等(deng);按與(yu)(yu)閥(fa)(fa)體相(xiang)連的(de)(de)油路(lu)數分為(wei) 二通、三(san)通、四(si)通和(he)六(liu)通等(deng);操作(zuo)閥(fa)(fa)芯運動(dong)(dong)(dong)的(de)(de)方(fang)(fang)式(shi)(shi)有 手動(dong)(dong)(dong)、機(ji)動(dong)(dong)(dong)、電動(dong)(dong)(dong)、液(ye)(ye)動(dong)(dong)(dong)、電液(ye)(ye)等(deng)型式(shi)(shi)。

阿托斯ATOS換向閥(fa)(fa)按(an)閥(fa)(fa)芯(xin)相對(dui)于閥(fa)(fa)體的(de)運(yun)動方式：

      滑閥(fa)(fa)和(he)轉閥(fa)(fa)按(an)(an)操作(zuo)方式：手(shou)動(dong)(dong)、機動(dong)(dong)、電磁動(dong)(dong)、液(ye)動(dong)(dong)和(he)電液(ye)動(dong)(dong)等按(an)(an)閥(fa)(fa)芯(xin)工作(zuo)時在(zai)閥(fa)(fa)體中(zhong)所處的位置：二(er)位和(he)三位等按(an)(an)換向閥(fa)(fa)所控制的通(tong)路數不同：二(er)通(tong)、三通(tong)、四通(tong)和(he)五通(tong)等。

       1、工作(zuo)原(yuan)理(li)滑閥(fa)(fa)式換(huan)向(xiang)(xiang)(xiang)(xiang)閥(fa)(fa)的(de)工作(zuo)原(yuan)理(li)圖，當閥(fa)(fa)芯向(xiang)(xiang)(xiang)(xiang)右(you)移(yi)動一定(ding)的(de)距離時(shi)，由液壓泵輸(shu)出的(de)壓力油(you)從閥(fa)(fa)的(de)p口經a口輸(shu)向(xiang)(xiang)(xiang)(xiang)液壓缸左腔，液壓缸右(you)腔的(de)油(you)經b口流(liu)(liu)回油(you)箱，液壓缸活塞向(xiang)(xiang)(xiang)(xiang)右(you)運動；反(fan)之，若閥(fa)(fa)芯向(xiang)(xiang)(xiang)(xiang)左移(yi)動某一距離時(shi)，液流(liu)(liu)反(fan)向(xiang)(xiang)(xiang)(xiang)，活塞向(xiang)(xiang)(xiang)(xiang)左運動。

       2、 換向閥(fa)的結構(gou)

       1） 手動(dong)換向閥利用手動(dong)杠桿來改變閥芯位置(zhi)實現換向。分彈(dan)簧(huang)自動(dong)復位（a）和彈(dan)簧(huang)鋼珠（b）定位兩(liang)種。

       2） 機(ji)動(dong)換(huan)向閥(fa)主要用(yong)來控制機(ji)械運(yun)動(dong)部件(jian)的行程(cheng)，借(jie)助(zhu)于安(an)裝在工作臺上(shang)的檔鐵或凸輪(lun)迫(po)使閥(fa)芯(xin)運(yun)動(dong)，從而(er)控制液流方向。

       3） 電(dian)(dian)磁換向閥(fa)利用電(dian)(dian)磁鐵的通(tong)(tong)電(dian)(dian)吸合(he)與斷(duan)(duan)電(dian)(dian)釋(shi)放(fang)而直(zhi)接推動閥(fa)芯(xin)(xin)來控制(zhi)液(ye)流方向。它是電(dian)(dian)氣系(xi)統和液(ye)壓系(xi)統之間的信號轉換元(yuan)件(jian)。 二位三通(tong)(tong)交流電(dian)(dian)磁閥(fa)結構。油(you)口(kou) p和a相通(tong)(tong)，油(you)口(kou)b斷(duan)(duan)開；當(dang)電(dian)(dian)磁鐵通(tong)(tong)電(dian)(dian)吸合(he)時，推桿1將閥(fa)芯(xin)(xin)2推向右瑞，這時油(you)口(kou)p和a斷(duan)(duan)開，而與b相通(tong)(tong)。當(dang)電(dian)(dian)磁鐵斷(duan)(duan)電(dian)(dian)釋(shi)放(fang)時，彈簧3推動閥(fa)芯(xin)(xin)復位。

      4） 液動換向(xiang)閥利用控制油(you)(you)路(lu)的壓力油(you)(you)來改變(bian)閥芯位置的換向(xiang)閥。閥芯是由(you)其兩端密封腔中油(you)(you)液的壓差來移動的

     電(dian)磁換(huan)向閥(fa)(fa)的(de)(de)(de)結構主體(ti)分為(wei)閥(fa)(fa)體(ti)以及(ji)位(wei)于閥(fa)(fa)體(ti)內(nei)的(de)(de)(de)圓柱形(xing)閥(fa)(fa)芯(xin)(xin)。閥(fa)(fa)芯(xin)(xin)可在閥(fa)(fa)體(ti)孔內(nei)做軸向運(yun)動。閥(fa)(fa)體(ti)孔內(nei)的(de)(de)(de)環形(xing)沉(chen)割(ge)槽(cao)與閥(fa)(fa)體(ti)底面上(shang)所開(kai)(kai)的(de)(de)(de)相應的(de)(de)(de)主油(you)(you)孔（P,A,B,T）相通。閥(fa)(fa)芯(xin)(xin)的(de)(de)(de)臺肩將沉(chen)割(ge)槽(cao)遮(zhe)(zhe)蓋即(ji)封堵時候，此(ci)(ci)槽(cao)所通油(you)(you)路即(ji)被切(qie)斷(duan)，閥(fa)(fa)芯(xin)(xin)臺肩不僅遮(zhe)(zhe)蓋沉(chen)割(ge)槽(cao)，還將沉(chen)割(ge)槽(cao)旁側的(de)(de)(de)閥(fa)(fa)體(ti)內(nei)孔遮(zhe)(zhe)蓋一(yi)段(duan)長度。當(dang)閥(fa)(fa)芯(xin)(xin)運(yun)動，不遮(zhe)(zhe)蓋沉(chen)割(ge)槽(cao)時候，此(ci)(ci)時閥(fa)(fa)芯(xin)(xin)打開(kai)(kai)，油(you)(you)路就與其他油(you)(you)路相通。由此(ci)(ci)，借(jie)助(zhu)閥(fa)(fa)芯(xin)(xin)位(wei)于閥(fa)(fa)體(ti)內(nei)的(de)(de)(de)不同(tong)位(wei)置，電(dian)磁換(huan)向閥(fa)(fa)得以改變油(you)(you)路方向，控制不同(tong)油(you)(you)孔的(de)(de)(de)通斷(duan)。利用閥(fa)(fa)芯(xin)(xin)對閥(fa)(fa)體(ti)的(de)(de)(de)相對運(yun)動，使油(you)(you)路接通、關斷(duan)或變換(huan)油(you)(you)流的(de)(de)(de)方向，從(cong)而實現液壓執行元件及(ji)其驅動機構的(de)(de)(de)啟動、停止(zhi)或變換(huan)運(yun)動方向。

  阿托斯(si)ATOS電磁(ci)換(huan)(huan)向(xiang)(xiang)閥擁有不(bu)(bu)(bu)同(tong)(tong)的功(gong)能，他(ta)們對(dui)油路的控(kong)制(zhi)情況也(ye)有所區別。電磁(ci)換(huan)(huan)向(xiang)(xiang)閥的工作(zuo)不(bu)(bu)(bu)同(tong)(tong)主要借助于更換(huan)(huan)不(bu)(bu)(bu)同(tong)(tong)形(xing)式(shi)的閥芯，不(bu)(bu)(bu)同(tong)(tong)的閥芯對(dui)閥體沉割槽的遮蓋(gai)情況不(bu)(bu)(bu)同(tong)(tong)，進(jin)而形(xing)成不(bu)(bu)(bu)同(tong)(tong)的控(kong)制(zhi)功(gong)能

    阿托斯ATOS電(dian)(dian)(dian)磁(ci)(ci)(ci)換向(xiang)(xiang)閥(fa)(fa)的(de)操作(zuo)依靠(kao)電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)控(kong)制，無需人員操作(zuo)，容易實現自動(dong)化，以及(ji)(ji)遠程控(kong)制。電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵(tie)組件(jian)分為線圈以及(ji)(ji)電(dian)(dian)(dian)磁(ci)(ci)(ci)管(guan)兩大部分。電(dian)(dian)(dian)磁(ci)(ci)(ci)管(guan)內含有銜鐵(tie)以及(ji)(ji)推(tui)(tui)桿。結構(gou)上，電(dian)(dian)(dian)磁(ci)(ci)(ci)換向(xiang)(xiang)閥(fa)(fa)線圈內套裝電(dian)(dian)(dian)磁(ci)(ci)(ci)管(guan)，通電(dian)(dian)(dian)后在電(dian)(dian)(dian)磁(ci)(ci)(ci)力的(de)帶動(dong)下，銜鐵(tie)向(xiang)(xiang)方向(xiang)(xiang)移動(dong)，帶動(dong)推(tui)(tui)桿向(xiang)(xiang)前，推(tui)(tui)桿進(jin)而推(tui)(tui)動(dong)阿托斯ATOS電(dian)(dian)(dian)磁(ci)(ci)(ci)換向(xiang)(xiang)閥(fa)(fa)閥(fa)(fa)芯(xin)進(jin)行動(dong)作(zuo)。電(dian)(dian)(dian)磁(ci)(ci)(ci)換向(xiang)(xiang)閥(fa)(fa)發(fa)展至今，其結構(gou)已(yi)經基本固定，具有較高的(de)可靠(kao)性及(ji)(ji)通用
