*SMC電磁閥VX2120-02-1T：SMC流體閥的工作介質(zhì)
氣動(dòng)元件的工作介質(zhì)通常是壓縮空氣。SMC流體閥是指通過(guò)閥的工作介質(zhì)除空氣（包括真空狀態(tài)）及氬氣,、氮?dú)?、氦氣等惰性氣體外，還可以是水,、油,、蒸汽等多種液體和氣體,。

SMC流體閥幾種典型結(jié)構(gòu)

下圖是VCW系列的結(jié)構(gòu)原理圖。對(duì)于N.C.型,，電磁線圈3不通電時(shí),，閥芯關(guān)閉IN口與OUT口。當(dāng)電磁線圈通電時(shí),，動(dòng)鐵心組件4a克服復(fù)位彈簧6的彈簧力,，被靜鐵心2所被吸引，IN口與OUT開(kāi)啟,。N.C.型的圖形符號(hào)表示,，在不通電時(shí)，IN口至OUT口是封閉的,，但若OUT口與IN口對(duì)換,，則不能封閉。

VCA,、VCB、VCL,、VCS,、VCW及VDW系列的工作介質(zhì)比較單一，故閥的結(jié)構(gòu)簡(jiǎn)單,，體積和重量都比對(duì)應(yīng)口徑的VX系列要小而輕,，價(jià)格也低些。

VXR2系列是SMC防水錘型二位二通先導(dǎo)式電磁閥,，在IN側(cè)沒(méi)有壓力或很低壓力下,，由于提升彈簧的反力使主閥芯開(kāi)啟，故稱為零差壓動(dòng)作型,，即zui低動(dòng)作壓力差為零,。
