CamozziKN000-303-KY3 電磁閥
原理:通電時,電磁閥線圈產(chǎn)生電磁力把關閉件從閥座上提起,閥門打開; 斷電時,電磁力消失,彈簧力把關閉件壓在閥座上,閥門關閉。特點:在真空、 負壓、零壓時能正常工作,但通徑一般不超過25mm。

原理:它是一種直動和先導式相結合的原理,當入口與出口沒有壓差時,通電后,電磁力直接把先導小閥和主閥關閉件依次向上提起,閥門打開。當入口與出口達到啟動壓差時,通電后,電磁力先打開先導小閥,主閥下壓力上升,上腔壓力下降,從而利用彈簧力或介質壓力推動關閉件,向下移動,使閥門關閉。特點:在零壓或真空、高壓時亦能可靠動作,但功率較大,要求必須水平安裝。原理:通電時,電磁力把先導孔打開,上腔室壓力迅速下降,在關閉件周圍形成上低下高的壓差,流體壓力推動關閉件移動,閥門打開;斷電時,彈簧力把先導孔關閉,入口壓力通過旁通孔迅速進入上腔室在關閥件周圍形成下低上高的壓差,流體壓力推動關閉件向下移動,關閉閥門。特點:流體壓力范圍上限較高,可任意安裝(需定制)但必須滿足流體壓差條件。電-氣轉化組件將電訊號轉化為氣動訊號,電氣訊號輸入控制了氣動輸出。常用的電-氣轉換組件是電磁閥(Solenoidactuatedvalves)。電磁閥既是電器控制部分和氣動執(zhí)行部分的接口,也是和氣源系統(tǒng)的接口。電磁閥接受命令 去釋放,停止或改變壓縮空氣的流向,在電-氣動控制中,電磁閥可以實現(xiàn)的功能有:氣動執(zhí)行組件動作的方向控制,ON/OFF開關量控制,OR/NOT/AND 邏輯控制。在電磁閥家族中,重要的是電磁控制換向閥
