style="text-indent:25px">電磁閥原理是用浮筒杠桿等控制氣缸內(nèi)氣動(dòng)膜片動(dòng)作，從而使閥體上大排氣口啟閉。這類排氣閥結(jié)構(gòu)上的主要特點(diǎn)是，大小排氣口或*大排氣口的有效排氣口徑不小于排氣閥公稱直徑的70%～80%。一般設(shè)計(jì)者在選擇排氣閥時(shí)是以排氣閥的公稱口徑計(jì)算排氣量的。氣缸式排氣閥則能滿足設(shè)計(jì)要求，真正起到防止管道氣爆的作用。電磁閥缺點(diǎn)是排氣口徑及排氣量小，對(duì)于管徑較小的輸配水管，經(jīng)計(jì)算分析后，可以采用，但管道充水速度應(yīng)嚴(yán)格控制(尤其是在平時(shí)突然停泵后)，否則也可能出現(xiàn)憋氣甚爆管事故。氣缸式排氣閥因排氣口徑大，排氣速度高，且在任何情況下均可高速排氣，理論和大量實(shí)踐證明，這種排氣閥可大限度地滿足設(shè)計(jì)要求，對(duì)輸水管道尤其是大型輸水管道排氣順暢，防止爆管和運(yùn)行穩(wěn)定的作用是非常明顯的。無(wú)錫耐腐蝕電磁閥價(jià)格表電磁閥的用途較為普遍，由于使用的行業(yè)不同，其圖型略有差別。</p><div

style="text-indent:25px">先導(dǎo)式電磁閥工作原理：常閉型電磁閥：當(dāng)電磁線圈通電時(shí)，動(dòng)鐵芯吸合，打開(kāi)卸壓孔，使作用在主閥芯上部的壓力降低，從而依靠壓差將主閥芯推向上方，閥門打開(kāi)；當(dāng)電磁線圈斷電后，動(dòng)鐵芯因自重及動(dòng)鐵芯彈簧作用下落，關(guān)閉卸壓孔，使主閥芯上表面形成壓力，加上主閥芯壓簧及自重，主閥芯下落至閥口，閥門關(guān)閉。常開(kāi)電磁閥：當(dāng)電磁線圈通電后，泄壓孔與常閉相反形成關(guān)閉狀態(tài)，閥門關(guān)閉。當(dāng)電磁線圈斷電后，泄壓孔與常閉相反形成打開(kāi)狀態(tài)，閥門打開(kāi)。先導(dǎo)式電磁閥采用不銹鋼活塞，使閥的承壓能力提高，活塞環(huán)伸展自如，金屬活塞與閥腔不產(chǎn)生直接摩擦，克服了易卡死的弊端，介質(zhì)截止處采用相對(duì)應(yīng)的材料密封，提高了閥的密封性能，延長(zhǎng)了電磁閥的使用壽命。</p><p style="text-indent:25px">檢查電冰箱電磁閥時(shí)，不管是單穩(wěn)態(tài)還是雙穩(wěn)態(tài)電磁閥均有發(fā)生泄露的可能，因此對(duì)電磁閥檢漏也是不可缺少的一步。在對(duì)電冰箱高低壓分別進(jìn)行保壓檢漏時(shí)，電磁閥部分是連接于高壓側(cè)的，因電磁閥體較大又安裝于壓縮機(jī)旁的狹窄空間里，較好能將閥體拆開(kāi)。拆開(kāi)后，如果發(fā)現(xiàn)閥體的焊接部位有油跡，說(shuō)明此處有明顯的漏點(diǎn)，需要加固焊接。若無(wú)明顯油跡，則應(yīng)用肥皂沫涂于電磁閥焊縫四周，如有氣泡溢出，說(shuō)明有微小漏。檢測(cè)時(shí)切不可將電磁閥浸于水中，否則易造成驅(qū)動(dòng)板，線圈受潮短路。先導(dǎo)式電磁閥是工業(yè)過(guò)程自動(dòng)化控制系統(tǒng)的執(zhí)行元件。</p><div
