style="text-indent:25px">在氣動(dòng)回路中，電磁控制換向閥的作用是控制氣流通道的通、斷或改變壓縮空氣的流動(dòng)方向。主要工作原理是利用電磁線圈產(chǎn)生的電磁力的作用，推動(dòng)閥芯切換，實(shí)現(xiàn)氣流的換向。按電磁控制部分對(duì)換向閥推動(dòng)方式的不同，可以分為直動(dòng)式電磁閥和先導(dǎo)式電磁閥。直動(dòng)式電磁閥直接利用電磁力推動(dòng)閥芯換向，而先導(dǎo)式換向閥則利用電磁先導(dǎo)閥輸出的先導(dǎo)氣壓推動(dòng)閥芯換向。常閉直動(dòng)式電磁閥壓力0.6MPA,就是我們常說的6公斤壓力,0-0.6是零壓起動(dòng)的,先導(dǎo)式的電磁閥零壓才無法起動(dòng),電磁閥一般有三種型式,一種是直動(dòng)的,直接用電磁吸力帶動(dòng)動(dòng)鐵芯及密封件，這種適用在通徑較小的電磁閥，一種是分步直動(dòng)式，一種是先導(dǎo)式的。宣城直動(dòng)式電磁閥工藝電磁閥主要優(yōu)點(diǎn)是體積小，動(dòng)作可靠，維修方便，價(jià)格便宜。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="宣城直動(dòng)式電磁閥工藝,直動(dòng)式電磁閥" src="https://tyunfile.71360.com/UploadFile/shplfb/637368282813837891/923890.png"></div><p style="text-indent:25px">電磁閥直動(dòng)式和先導(dǎo)式區(qū)別：介質(zhì)潔凈度要求：先導(dǎo)式電磁閥對(duì)流通介質(zhì)的純凈度要求比較高，直動(dòng)式則沒有那么嚴(yán)格了。功率和損耗：直動(dòng)式電磁閥功率和損耗要比先導(dǎo)式更大。流通能力：先導(dǎo)式電磁閥的流通能力相比于直動(dòng)式要大一些，一般CV值可達(dá)3以上，而直動(dòng)電磁閥的一般CV值都是小于1。響應(yīng)時(shí)間：直動(dòng)式電磁閥的啟動(dòng)速度相比先導(dǎo)式來得快，多用于快速切斷的場(chǎng)所。因?yàn)橄葘?dǎo)式電磁閥是通5、電后小閥先開啟，主閥后開，直動(dòng)式電磁閥則是主閥直接打開。承受壓力：先導(dǎo)式電磁閥的承受液壓力，比直通式電磁閥承受壓力大。</p><p style="text-indent:25px">操縱電磁閥用的電磁鐵分為交、直流兩種：交流電磁鐵的電壓一般為220伏。其特點(diǎn)是啟動(dòng)力較大，換向時(shí)間短，價(jià)廉。但當(dāng)閥芯卡住或吸力不夠而使鐵芯吸不上時(shí)，電磁鐵容易因電流過大而燒壞，故工作可靠性較差，動(dòng)作時(shí)有沖擊，壽命較低。直流電磁鐵電壓一般為24伏。其優(yōu)點(diǎn)是工作可靠，不會(huì)因閥芯卡住而燒壞，壽命長(zhǎng)，體積小，但啟動(dòng)力較交流電磁鐵小，而且在無直流電源時(shí)，需整流設(shè)備。為了提高電磁換向閥的工作可靠性和壽命，近年來，國(guó)內(nèi)外正日益普遍地采用濕電磁鐵，這種電磁鐵與滑閥推桿間無須密封，消除了O形密封圈處的摩擦力，它的電磁線圈外面直接用工程塑料封固，不另作金屬外殼，這樣既保證了絕緣，又利于散熱，所以工作可靠，沖擊小，壽命長(zhǎng)。直動(dòng)式電磁閥普遍應(yīng)用于冶金、石化、航天、船舶重工、消防、工業(yè)窯爐、電力、干燥設(shè)備。</p><div

style="text-indent:25px">分步直動(dòng)式電磁閥一般是用于壓力不穩(wěn)定的場(chǎng)合，零壓可啟動(dòng)，壓力上限也較大，即0-0.6MPa也可0-1.6MPa，口徑范圍也比直動(dòng)式的更廣，特別適合口徑大，零壓可動(dòng)作，有壓力能使用的場(chǎng)所。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。外漏是指閥桿填料部位的泄露。宣城直動(dòng)式電磁閥工藝</p><p

style="text-indent:25px">直動(dòng)式電磁閥可以配合不同的電路來實(shí)現(xiàn)預(yù)期的控制，而控制的精度和靈活性都能夠保證。電磁閥是用電磁控制的工業(yè)設(shè)備，是用來控制流體的自動(dòng)化基礎(chǔ)元件，屬于執(zhí)行器，并不限于液壓、氣動(dòng)。用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。電磁閥可以配合不同的電路來實(shí)現(xiàn)預(yù)期的控制，而控制的精度和靈活性都能夠保證。電磁閥有很多種，不同的電磁閥在控制系統(tǒng)的不同位置發(fā)揮作用，較常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等。宣城直動(dòng)式電磁閥工藝</p></p><br
