style="text-indent:25px">如果通過電磁閥來調(diào)節(jié)管道的流量。首先我們要明確一點(diǎn)的是，單獨(dú)的一直電磁閥它的流道只具備兩個狀態(tài)，通和斷，因?yàn)殡姶砰y的響應(yīng)速度是極快的，都是毫秒級的，電磁閥啟動的瞬間吸力是較大的，行程一般是從幾毫米到厘米級，無論是從電磁效應(yīng)還是慣性定律上來講，閥芯是沒法懸停的，更不可能說像控制調(diào)節(jié)閥那樣給4~20mA信號那樣，可以任意位置較準(zhǔn)控制了。雙聯(lián)或者多聯(lián)組合電磁閥這是一種不同大小的電磁閥組合在一起。大閥開啟，使得在較短的時(shí)間內(nèi)接近完成；然后大閥關(guān)閉，由小閥補(bǔ)充，從而保證流量精度，此項(xiàng)技術(shù)國外已應(yīng)用多年。</p><p style="text-indent:25px">防爆電磁閥的安全性:腐蝕性介質(zhì)：對于強(qiáng)腐蝕的介質(zhì)必須選用隔離膜片式。中性介質(zhì)，也宜選用銅合金為閥殼材料的電磁閥，否則，閥殼中常有銹屑脫落，尤其是動作不頻繁的場合。氨用閥則不能采用銅材。性環(huán)境：必須選用相應(yīng)防爆等級產(chǎn)品，露天安裝或粉塵多場合應(yīng)選用防水，防塵品種。電磁閥公稱壓力應(yīng)超過管內(nèi)較高工作壓力。管道參數(shù),根據(jù)介質(zhì)流向要求及管道連接方式選擇閥門通口及型號。例如，用于一條管道向兩條管道切換的。控制兩條管道匯流的。根據(jù)流量和閥門KV值選定公稱通徑，也可選同管道內(nèi)徑。請注意有的廠家未標(biāo)有KV值，往往閥孔尺寸小于接口管徑，切不可貪圖價(jià)低而誤事。電磁閥應(yīng)保證在電源電壓為額定電壓的15%-10%波動范圍內(nèi)正常工作。</p><div
