style="text-indent:25px">不銹鋼油煙機(jī)止回閥工作原理：不銹鋼油煙機(jī)止回閥由主閥、單向閥、針型閥、球閥、微形過(guò)濾器和壓力表組成水力控制接管系統(tǒng)。利用水力自動(dòng)操作，可使主閥得到極好的開(kāi)啟或關(guān)閉速度。防止水鍾水擊的產(chǎn)生，以達(dá)到緩閉消聲的效果。當(dāng)不銹鋼油煙機(jī)止回閥從進(jìn)口端給水時(shí)，水通過(guò)微型過(guò)濾器、針型閥、單向閥進(jìn)入主閥控制室，再經(jīng)過(guò)球閥排水至下游。因?yàn)獒樞烷y開(kāi)度小于球閥開(kāi)度，即主閥控制室的排水速度大于進(jìn)水速度，因此控制室壓力降低，作用于主閥盤(pán)下端的進(jìn)口壓力打開(kāi)主閥向下游供水。當(dāng)煙道停止供水時(shí)，若下游水開(kāi)始回流，一部分回流水經(jīng)球閥進(jìn)入主控制室，由于單向閥作用，回流水不能從主控制室流出，引起主控制室逐漸升壓，緩緩關(guān)閉主閥。余姚抽煙機(jī)止回閥油煙機(jī)止回閥一般適用于中等口徑的場(chǎng)合。</p><div

style="text-indent:25px">國(guó)家建設(shè)部將油煙機(jī)止回閥列為必須安裝的物件主要原因在于防火油煙機(jī)止回閥可以防止火災(zāi)通過(guò)公共煙道快速蔓延，火災(zāi)的發(fā)生大部分原因是做飯的時(shí)候用火不慎，油鍋無(wú)人看管，加之對(duì)廚房油煙管道清洗不及時(shí)，油污堆積嚴(yán)重，遇明火或高溫?zé)煔夂?，油垢被引燃所致。煙道著火了，油煙機(jī)中的塑料止回閥不一會(huì)就會(huì)被燒壞、出現(xiàn)了火勢(shì)通過(guò)煙道快速蔓延的結(jié)果。而油煙機(jī)止回閥采用的是耐高溫的不銹鋼材料，所以在火災(zāi)發(fā)生的時(shí)候，具有很強(qiáng)的保護(hù)性能，不*可以防止火勢(shì)通過(guò)煙道蔓延，也能防止煙氣通過(guò)煙道蔓延，為室內(nèi)人員贏得了更長(zhǎng)的待救時(shí)間。油煙機(jī)止回閥的具有非常可靠的切斷動(dòng)作。余姚抽煙機(jī)止回閥</p><p
