FESTO電磁閥隔磁套管內的鐵芯完成,不存在動密封,所以外漏易堵絕。電動閥力矩控制不易,容易產生內漏,甚至拉斷閥桿頭部;電磁閥的結構型式容易控制內泄漏,直至降為零。所以,電磁閥使用特別安全,尤其適用于腐蝕性、有毒或高低溫的介質。
FESTO電磁閥的用途電磁閥用于液體和氣體管路的開關控制,是兩位DO控制。一般用于小型管道的控制。電動閥用于液體、氣體和風系統管道介質流量的模擬量調節,是AI控制。在大型閥門和風系統的控制中也可以用電動閥做兩位開關控制。電磁閥只能用作開關量,是DO控制,只能用于小管道控制,常見于DN50及以下管道,往上就很少了。電動閥可以有AI反饋信號,可以由DO或AO控制,比較見于大管道和風閥等。1.開關形式電磁閥通過線圈驅動,只能開或關,開關時動作時間短。電動閥的驅動一般是用電機,開或關動作完成需要一定的時間模擬量的,可以做調節。2.工作性質電磁閥一般流通系數很小,而且工作壓力差很小。比如一般25口徑的電磁閥流通系數比15口徑的電動球閥小很多
)FESTO型號多樣,用途廣泛。電磁閥雖有先天不足,優點仍十分突出,所以就設
計成多種多樣的產品,滿足各種不同的需求,用途極為廣泛。電磁閥技術的進步也都是圍繞著如何克服先天不足,如何更好地發揮固有優勢而展開。FESTO電磁閥是用來控制流體方向的自動化基礎元件,屬于執行器;通常用于機械控制和工業閥門上面,對介質方向進行控制,從而達到對閥門開關的控制。工作原理電磁閥里有密閉的腔,在不同位置開有通孔,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擋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缸的活塞,活塞又帶動活塞桿,活塞桿帶動機械裝置動。這樣通過控制電磁鐵的電流通斷就控制了機械運動。FESTO費斯托電磁閥從原理上分為三大類:1)直動式電磁閥:原理:通電時,電磁線圈產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。2)分步直動式電磁閥: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。3)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。2.電磁閥從閥結構和材料上的不同與原理上的區別,分為六個分支小類:直動膜片結構、分步直動膜片結構、先導膜片結構、直動活塞結構、分步直動活塞結構、先導活塞結構。
