上海供應德國REXROTH力士樂電磁閥 力士樂Rexroth電磁閥從原理上分為三大類 （ 即：直動式、分步童先導式 ） 而從閥瓣結構和材料上的不同與原理上的差別又分為六個分支小類 （ 直動膜片結構、分步重片結構、先導膜式結構、直動活塞結構、分步直動活塞結構、先導活塞結構 ）
力士樂直動式燃氣電磁閥：電磁線圈發(fā)生電磁力把封閉件從閥座上提起，燃氣電磁閥工作原理：通電時。閥門打開;斷電時，電磁力消散，彈簧把封閉件壓在閥座上，閥門封閉。但通徑一般不超過 25mm 力士樂Rexroth電磁閥電磁閥特點：真空、負壓、零壓時能正常工作。 力士樂直動式燃氣電磁閥：當進口與入口沒有壓差時，燃氣電磁閥工作原理：一種直動和先導式相聯(lián)合的原理。通電后，電磁力直接把先導小閥和主閥封閉件依次向上提起，閥門打開。當進口與出口達到啟動壓差時，通電后，電磁力先導小閥，主閥下腔壓力上升，上腔壓力降落，從而利用壓差把主閥向上推開;斷電時，先導閥利用彈簧力或介質壓力推動封閉件，向下移動，使閥門封閉。但功率較大，力士樂Rexroth電磁閥電磁閥特點：零壓差或真空、高壓時亦能可 * 動作。請求必需水平裝置。
電磁閥原理：
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，電磁力先導小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時，先導閥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： 在零壓差或真空、高壓時亦能可動作，但功率較大，要求必須水平安裝 德國REXROTH力士樂先導式電磁閥：
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向上移動，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 。 力士樂先導式燃氣電磁閥：燃氣電磁閥把先導孔打開，燃氣電磁閥工作原理：通電時。上腔室壓力敏捷降落，封閉件四周形成上低下高的壓差，流體壓力推動封閉件向上移動，閥門打開;斷電時，彈簧力把先導孔封閉，進口壓力通過旁通孔敏捷腔室在關閥件四周形成下低上高的壓差，流體壓力推動封閉件向下移動，封閉閥門。可任意安裝 （ 需定制 ） 但必需滿足流體壓差條件。 力士樂Rexroth電磁閥電磁閥特點：流體壓力范疇上限較高。 力士樂REXROTH電磁閥里有密閉的腔，在的不同位置開有通孔，每個孔都通向不同的油管，腔中間是閥，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來檔住或漏出不同的排油的孔，而進油孔是常開的，液壓油就會進入不同的排油管，然后通過油的壓力來推動油剛的活塞，活塞又帶動活塞桿，活塞竿帶動機械裝置動。這樣通過控制電磁鐵的電流就控制了機械運動。
