描述

對于小型自動(dòng)控制設(shè)備，氣管一般選用8~12mm的工業(yè)膠氣管。在電氣上來說，兩位三通電磁閥一般為單電控(即單線圈)，兩位五通電磁閥一般為雙電控(即雙線圈)。線圈電壓等級一般采用DC24V、AC220V等。兩位三通電磁閥分為常閉型和常開型兩種，常閉型指線圈沒通電時(shí)氣路是斷的，常開型指線圈沒通電時(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，這相當(dāng)于“點(diǎn)動(dòng)”。【電磁閥的分類_電磁閥的工作原理圖】常開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，線圈一旦斷電，氣路就會(huì)接通，這也是“點(diǎn)動(dòng)”
