style="text-indent:25px">不銹鋼油煙機止回閥的選用原則：高溫、高壓介質(zhì)的管路或裝置上宜選用不銹鋼油煙機止回閥。如火電廠、核電站，油化工體系的高溫、高壓管路上。管路上對流阻要求不嚴(yán)的管路上。即對壓力損失考慮不大的當(dāng)?shù)?。小型閥門可選用針閥、外表閥、取樣閥、壓力計閥等。有流量調(diào)理或壓力調(diào)理，但對調(diào)理精度要求不高，并且管路直徑又比較小，如公稱通經(jīng)≤50mm的管路上，宜選用。合成工業(yè)生產(chǎn)中的小化肥和大化肥宜選用公稱壓力PN160公稱壓力16MPa或PN320公稱壓力32MPa的高壓角式不銹鋼油煙機止回閥或高壓角式節(jié)流閥。奉化廚房抽油煙機止回閥生產(chǎn)廠家油煙機止回閥的有著很長的使用壽命。</p><div

style="text-indent:25px">主次式煙道。主次式煙道截面上由兩個并列矩形煙管構(gòu)成，垂直穿越各樓層。次煙道在住宅每層中設(shè)一連接排油煙機的進(jìn)風(fēng)口，次煙道與主煙道距進(jìn)風(fēng)口-定距離處相匯，主煙道底層有一補風(fēng)口。其原理是通過抽油煙機將煙氣推入次煙道中，用抽油煙機推動力和油煙溫度上浮力使油煙上升一段距離后再進(jìn)入主煙道排出屋面。這樣由于煙氣始終向上運動以及油煙機止回閥的作用，避免了煙氣產(chǎn)生的倒灌和串味現(xiàn)象。變壓式煙道。壓式煙道是將各層的煙道做成不同的截面形式，下層煙道通過主次煙道排氣氣，而靠近屋面的煙道如同單煙道的作用，直接將油煙排入煙道排出。</p><p style="text-indent:25px">防火油煙機止回閥的性能優(yōu)點：1、防火油煙機止回閥較好選擇全金屬結(jié)構(gòu)，不銹鋼更好，如果有塑件，鋁等熔點低的部件，則達(dá)不上防火規(guī)定。2、看選擇防火油煙機止回閥的密閉性，防火裝置不可以應(yīng)用彈簧直接拄抵閥頁：一個是在高溫條件下彈簧彈力無效失去了功效，二是彈簧有彈力壓不死閥頁。防火裝置應(yīng)合理有效鎖住閥頁(實際就是說反方向用手指推動閥頁，看能不能開啟，開啟即防火無效）。3、看選擇商品的自然通風(fēng)性，選擇的商品閥頁較好并不是斜置單片閥頁構(gòu)造，那樣會造成氣體下壓，干擾往上面自然通風(fēng)。4、選擇的商品應(yīng)設(shè)立向上導(dǎo)流裝置，能指引氣體往上面流動。假如閥頁是單片斜置構(gòu)造裝有向上導(dǎo)流構(gòu)造，則會造成出風(fēng)口縮小，出現(xiàn)渦流等問題，應(yīng)防止選擇。油煙機止回閥產(chǎn)品材料的控制，現(xiàn)代社會講究的是低碳和環(huán)保。</p><div
