CamozziKN000-303-KY3 電磁閥

原理：通電時，電磁閥線圈產(chǎn)生電磁力把關(guān)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(guān)閉件壓在閥座上，閥門關(guān)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。

CamozziKN000-303-KY3 電磁閥

原理：它是一種直動和先導式相結(jié)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(guān)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(zhì)壓力推動關(guān)閉件，向下移動，使閥門關(guān)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(guān)閉件周圍形成上低下高的壓差，流體壓力推動關(guān)閉件移動，閥門打開；斷電時，彈簧力把先導孔關(guān)閉，入口壓力通過旁通孔迅速進入上腔室在關(guān)閥件周圍形成下低上高的壓差，流體壓力推動關(guān)閉件向下移動，關(guān)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(zhuǎn)化組件將電訊號轉(zhuǎn)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(zhuǎn)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(guān)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
