威格士VICKERS電磁閥/VICKERS中國(guó)
VICKERS電磁閥出來(lái)的先導(dǎo)油控制主換向閥閥芯的移動(dòng),使工作泵的來(lái)油進(jìn)入動(dòng)臂油缸實(shí)現(xiàn)動(dòng)臂上升。比例先導(dǎo)減壓閥的輸出壓力越大,控制主換向閥閥芯的位移越大,主換向閥通過的流量越大,動(dòng)臂上升的速度越快。當(dāng)操作手柄拉*限位置時(shí),手柄中的限位電磁鐵通電,手柄在極限位置被吸合。動(dòng)臂以zui大的速度上升,當(dāng)升至動(dòng)臂上位限位開關(guān)所限定的位置時(shí),操作手柄限位電磁鐵斷電,手柄自動(dòng)恢復(fù)到中位,動(dòng)臂就可保持在所限定的位置。在動(dòng)臂上升的過程中,若需要?jiǎng)颖墼谀骋晃恢猛A?,則需將操作手柄退回中位。

VICKERS電磁閥和安全閥為一體,組成先導(dǎo)式壓力閥,該閥即是卸荷閥又是安全閥,有時(shí)又是溢流閥.卸荷時(shí)其控制油道貫穿各路換向閥,同前述卸荷油道.當(dāng)各路換向閥處于中立位置時(shí),卸荷閥的控制油道(見圖1b和圖2)貫穿各路換向閥并與油箱連通.卸荷時(shí),大部分油液卸荷,通道短,壓力損失低.任一路閥換向工作,便切斷控制油道,油源來(lái)油就從換向閥進(jìn)入執(zhí)行元件工作,其工作壓力大小由導(dǎo)閥控制.此時(shí)系統(tǒng)壓力為導(dǎo)閥調(diào)整壓力.該種卸荷方式,即使換向閥路數(shù)增加,只是控制油道增加,卸荷壓力增加不大,始終保持較低卸荷壓力,此種卸荷方式多用于手動(dòng)換向閥,卸荷可靠.
