FESTO電磁閥隔磁套管內(nèi)的鐵芯完成,不存在動(dòng)密封,所以外漏易堵絕。電動(dòng)閥力矩控制不易,容易產(chǎn)生內(nèi)漏,甚至拉斷閥桿頭部;電磁閥的結(jié)構(gòu)型式容易控制內(nèi)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(zhì)。
FESTO電磁閥的用途電磁閥用于液體和氣體管路的開關(guān)控制,是兩位DO控制。一般用于小型管道的控制。電動(dòng)閥用于液體、氣體和風(fēng)系統(tǒng)管道介質(zhì)流量的模擬量調(diào)節(jié),是AI控制。在大型閥門和風(fēng)系統(tǒng)的控制中也可以用電動(dòng)閥做兩位開關(guān)控制。電磁閥只能用作開關(guān)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(dòng)閥可以有AI反饋信號(hào),可以由DO或AO控制,比較見于大管道和風(fēng)閥等。1.開關(guān)形式電磁閥通過線圈驅(qū)動(dòng),只能開或關(guān),開關(guān)時(shí)動(dòng)作時(shí)間短。電動(dòng)閥的驅(qū)動(dòng)一般是用電機(jī),開或關(guān)動(dòng)作完成需要一定的時(shí)間模擬量的,可以做調(diào)節(jié)。2.工作性質(zhì)電磁閥一般流通系數(shù)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(shù)比15口徑的電動(dòng)球閥小很多
)FESTO型號(hào)多樣,用途廣泛。電磁閥雖有先天不足,優(yōu)點(diǎn)仍十分突出,所以就設(shè)
計(jì)成多種多樣的產(chǎn)品,滿足各種不同的需求,用途極為廣泛。電磁閥技術(shù)的進(jìn)步也都是圍繞著如何克服先天不足,如何更好地發(fā)揮固有優(yōu)勢(shì)而展開。FESTO電磁閥是用來控制流體方向的自動(dòng)化基礎(chǔ)元件,屬于執(zhí)行器;通常用于機(jī)械控制和工業(yè)閥門上面,對(duì)介質(zhì)方向進(jìn)行控制,從而達(dá)到對(duì)閥門開關(guān)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(gè)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(huì)被吸引到哪邊,通過控制閥體的移動(dòng)來擋住或漏出不同的排油的孔,而進(jìn)油孔是常開的,液壓油就會(huì)進(jìn)入不同的排油管,然后通過油的壓力來推動(dòng)油缸的活塞,活塞又帶動(dòng)活塞桿,活塞桿帶動(dòng)機(jī)械裝置動(dòng)。這樣通過控制電磁鐵的電流通斷就控制了機(jī)械運(yùn)動(dòng)。FESTO費(fèi)斯托電磁閥從原理上分為三大類:1)直動(dòng)式電磁閥:原理:通電時(shí),電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起,閥門打開;斷電時(shí),電磁力消失,彈簧把關(guān)閉件壓在閥座上,閥門關(guān)閉。特點(diǎn):在真空、負(fù)壓、零壓時(shí)能正常工作,但通徑一般不超過25mm。2)分步直動(dòng)式電磁閥:原理:它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理,當(dāng)入口與出口沒有壓差時(shí),通電后,電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起,閥門打開。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí),通電后,電磁力先導(dǎo)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(shí),先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件,向下移動(dòng),使閥門關(guān)閉。特點(diǎn):在零壓差或真空、高壓時(shí)亦能可*動(dòng)作,但功率較大,要求必須水平安裝。3)先導(dǎo)式電磁閥:原理:通電時(shí),電磁力把先導(dǎo)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(dòng)關(guān)閉件向上移動(dòng),閥門打開;斷電時(shí),彈簧力把先導(dǎo)孔關(guān)閉,入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差,流體壓力推動(dòng)關(guān)閉件向下移動(dòng),關(guān)閉閥門。特點(diǎn):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(jié)構(gòu)和材料上的不同與原理上的區(qū)別,分為六個(gè)分支小類:直動(dòng)膜片結(jié)構(gòu)、分步直動(dòng)膜片結(jié)構(gòu)、先導(dǎo)膜片結(jié)構(gòu)、直動(dòng)活塞結(jié)構(gòu)、分步直動(dòng)活塞結(jié)構(gòu)、先導(dǎo)活塞結(jié)構(gòu)。
