style="font-size:20px;">兩位三通電磁閥分為常閉型和常開(kāi)型兩種，常閉型指線圈沒(méi)通電時(shí)氣路是斷的，常開(kāi)型指線圈沒(méi)通電時(shí)氣路是通的。 常閉型兩位三通電磁閥動(dòng)作原理：給線圈通電，氣路接通，線圈一旦斷電，氣路就會(huì)斷開(kāi)，這相當(dāng)于“點(diǎn)動(dòng)”。 常開(kāi)型兩位三通單電控電磁閥動(dòng)作原理：給線圈通電，氣路斷開(kāi)，線圈一旦斷電，氣路就會(huì)接通，這也是“點(diǎn)動(dòng)”。 兩位五通雙電控電磁閥動(dòng)作原理：給正動(dòng)作線圈通電，則正動(dòng)作氣路接通(正動(dòng)作出氣孔有氣)，即使給正動(dòng)作線圈斷電后正動(dòng)作氣路仍然是接通的，將會(huì)一直維持到給反動(dòng)作線圈通電為止。 給反動(dòng)作線圈通電，則反動(dòng)作氣路接通(反動(dòng)作出氣孔有氣)，即使給反動(dòng)作線圈斷電后反動(dòng)作氣路仍然是接通的，將會(huì)一直維持到給正動(dòng)作線圈通電為止。這相當(dāng)于“自鎖”。兩位三通電磁閥一般都是一進(jìn)兩出系列的。也有常開(kāi)常閉的說(shuō)法。</span></p> <div id="3iycgcs"
