style="text-indent:25px">電磁閥的外部泄漏會(huì)被阻止，內(nèi)部泄漏易于控制，使用安全：內(nèi)部泄露和外部泄漏是危害安全的因素。其他自動(dòng)控制閥通常會(huì)延伸閥桿，而電動(dòng)，氣動(dòng)和液壓執(zhí)行器會(huì)控制閥芯的旋轉(zhuǎn)或運(yùn)動(dòng)。有必要解決長期閥桿動(dòng)密封的泄漏問題；而電磁閥是通過電磁力作用在密封在磁套中的鐵芯上完成的，并且沒有動(dòng)態(tài)密封，因此泄漏很容易被堵住。電動(dòng)閥的扭矩控制不容易，容易產(chǎn)生內(nèi)部泄漏甚至使閥桿頭斷裂；電磁閥的結(jié)構(gòu)易于控制內(nèi)部泄漏，直到泄漏降至零為止。因此，電磁閥的使用非常安全，特別適用于腐蝕性，有毒或高溫和低溫介質(zhì)。電磁閥系統(tǒng)簡單，便接電腦，價(jià)格低謙。電磁閥本身結(jié)構(gòu)簡單，價(jià)格也低，比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。更卓著的是所組成的自控系統(tǒng)簡單得多，價(jià)格要低得多。上?；る姶砰y水控器流體的溫度必須小于選用電磁閥的標(biāo)定溫度。</p><div

style="text-indent:25px">電磁閥在流程生產(chǎn)中電磁閥很多時(shí)候是與氣動(dòng)調(diào)節(jié)閥和活塞執(zhí)行機(jī)構(gòu)配合使用，這時(shí)電磁閥只起輔助功能但作用十分重要。尤其是在工藝生產(chǎn)聯(lián)鎖中，電磁閥具有很重要的作用，如氣源有故障時(shí)工藝閥的開、關(guān)狀態(tài)；工藝生產(chǎn)安全對閥門動(dòng)作有要求時(shí)，大多需要通過電磁閥來控制。雙電控電磁閥通過兩側(cè)電磁線圈的通電、斷電來控制閥門的開關(guān)，當(dāng)一個(gè)線圈斷電，另一個(gè)未通電時(shí)可以保持閥門當(dāng)前位置不變，即使閥門具有了自鎖功能。為了生產(chǎn)安全，有的場合用一只電磁閥進(jìn)行控制不太安全，這時(shí)就有必要考慮電磁閥的冗余問題，當(dāng)一只電磁閥有故障時(shí)，另一只電磁閥仍能保持正常工作，這就保證了生產(chǎn)的安全性。</p><p style="text-indent:25px">管道聯(lián)系式電磁閥：電磁閥不但能夠應(yīng)用在氣動(dòng)系統(tǒng)中，在油壓的系統(tǒng)、水壓的系統(tǒng)中也能夠得到相同或者類似的應(yīng)用，比如低功率不供油小型電磁換向閥，密封件不需供油，排出的氣體不會(huì)污染環(huán)境，可用于食品、醫(yī)藥、電子等行業(yè)。隨著技術(shù)的不斷進(jìn)步，電磁閥技術(shù)與控制技術(shù)、計(jì)算機(jī)技術(shù)、電子技術(shù)相結(jié)合，已經(jīng)能夠進(jìn)行多種復(fù)雜的控制。比如可以把電磁閥應(yīng)用在智能控制領(lǐng)域，應(yīng)用在無線控制技術(shù)等方面。電磁閥正是因?yàn)槟軌蛴秒姶胚M(jìn)行控制，所以它能各種電子系統(tǒng)很好地接口，這也是它得到廣fan應(yīng)用的一個(gè)主要原因。電磁閥已經(jīng)廣fan地應(yīng)用在生產(chǎn)的各個(gè)領(lǐng)域中，隨著電磁控制技術(shù)和制造工藝的提高，電磁閥能夠?qū)崿F(xiàn)更加精巧的控制，為實(shí)現(xiàn)不同的氣動(dòng)系統(tǒng)、液壓系統(tǒng)發(fā)揮它的作用。電磁閥公稱壓力應(yīng)超過管內(nèi)較高的工作壓力。</p><div

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。電磁閥是用電磁控制的工業(yè)設(shè)備。上海化工電磁閥水控器</p><p
