美國VICKERS電磁閥原理：
當(dang)各(ge)路換向(xiang)閥(fa)(fa)(fa)處于中立位置時(shi)(shi)，卸(xie)荷(he)(he)閥(fa)(fa)(fa)的控制(zhi)油道(dao)貫(guan)穿各(ge)路換向(xiang)閥(fa)(fa)(fa)并與(yu)油箱(xiang)連通(tong)．卸(xie)荷(he)(he)時(shi)(shi)，大(da)部分油液卸(xie)荷(he)(he)，通(tong)道(dao)短，壓(ya)(ya)力(li)(li)損失低．任一路閥(fa)(fa)(fa)換向(xiang)工(gong)作，便切斷(duan)控制(zhi)油道(dao)，油源來油就從換向(xiang)閥(fa)(fa)(fa)進入(ru)執行元(yuan)件工(gong)作，其工(gong)作壓(ya)(ya)力(li)(li)大(da)小由導(dao)閥(fa)(fa)(fa)控制(zhi)．此時(shi)(shi)系統壓(ya)(ya)力(li)(li)為導(dao)閥(fa)(fa)(fa)調整壓(ya)(ya)力(li)(li)．該(gai)種卸(xie)荷(he)(he)方式(shi)，即使換向(xiang)閥(fa)(fa)(fa)路數(shu)增加(jia)，只是控制(zhi)油道(dao)增加(jia)，卸(xie)荷(he)(he)壓(ya)(ya)力(li)(li)增加(jia)不大(da)，始終(zhong)保(bao)持較(jiao)低卸(xie)荷(he)(he)壓(ya)(ya)力(li)(li)，此種卸(xie)荷(he)(he)方式(shi)多用(yong)于手動(dong)換向(xiang)閥(fa)(fa)(fa)，卸(xie)荷(he)(he)可靠。
美國VICKERS電磁閥使用:
VICKERS電(dian)(dian)磁(ci)(ci)閥(fa)(fa)出(chu)來的(de)先(xian)導油控制主(zhu)換(huan)向閥(fa)(fa)閥(fa)(fa)芯(xin)的(de)移(yi)動(dong)(dong)，使工作泵的(de)來油進入動(dong)(dong)臂(bei)(bei)油缸(gang)實現動(dong)(dong)臂(bei)(bei)上升(sheng)。比例先(xian)導減壓閥(fa)(fa)的(de)輸(shu)出(chu)壓力越大，控制主(zhu)換(huan)向閥(fa)(fa)閥(fa)(fa)芯(xin)的(de)位(wei)(wei)移(yi)越大，主(zhu)換(huan)向閥(fa)(fa)通過的(de)流(liu)量越大，動(dong)(dong)臂(bei)(bei)上升(sheng)的(de)速度(du)越快(kuai)。當操(cao)作手(shou)柄拉*限(xian)位(wei)(wei)置(zhi)時(shi)，手(shou)柄中的(de)限(xian)位(wei)(wei)電(dian)(dian)磁(ci)(ci)鐵(tie)通電(dian)(dian)，手(shou)柄在(zai)極(ji)限(xian)位(wei)(wei)置(zhi)被吸合。動(dong)(dong)臂(bei)(bei)以大的(de)速度(du)上升(sheng)，當升(sheng)至動(dong)(dong)臂(bei)(bei)上位(wei)(wei)限(xian)位(wei)(wei)開關所限(xian)定的(de)位(wei)(wei)置(zhi)時(shi)，操(cao)作手(shou)柄限(xian)位(wei)(wei)電(dian)(dian)磁(ci)(ci)鐵(tie)斷電(dian)(dian)，手(shou)柄自動(dong)(dong)恢復到中位(wei)(wei)，動(dong)(dong)臂(bei)(bei)就可保持在(zai)所限(xian)定的(de)位(wei)(wei)置(zhi)。在(zai)動(dong)(dong)臂(bei)(bei)上升(sheng)的(de)過程(cheng)中，若需要動(dong)(dong)臂(bei)(bei)在(zai)某一位(wei)(wei)置(zhi)停留(liu)，則需將操(cao)作手(shou)柄退(tui)回中位(wei)(wei)。
VICKERS電(dian)磁(ci)閥(fa)主要(yao)用在(zai)電(dian)氣(qi)液(ye)(ye)壓伺(si)服(fu)(fu)(fu)系統中作為執行元件(見液(ye)(ye)壓伺(si)服(fu)(fu)(fu)系統)。在(zai)伺(si)服(fu)(fu)(fu)系統中，液(ye)(ye)壓執行機構同電(dian)氣(qi)及(ji)氣(qi)動(dong)執行機構相比，具有快(kuai)速性(xing)(xing)好、單位重量輸出功率大、傳動(dong)平穩、抗干(gan)擾(rao)能力強等特(te)點。另一方面，在(zai)伺(si)服(fu)(fu)(fu)系統中傳遞信號和校正(zheng)特(te)性(xing)(xing)時多用電(dian)氣(qi)元件。因此，現代高性(xing)(xing)能的(de)伺(si)服(fu)(fu)(fu)系統也都采用電(dian)液(ye)(ye)方式，伺(si)服(fu)(fu)(fu)閥(fa)就是這種系統的(de)必需元件。
