style="text-indent:25px">如何挑選適合家用的油煙機(jī)止回閥？防火密閉性上必須要求：油煙機(jī)止回閥的防火裝置不能使用彈簧直接拄抵閥頁：一是在高溫條件下彈簧彈力失效失去作用，二是彈簧有彈力壓不死閥頁。防火裝置應(yīng)有效鎖死閥頁(具體就是反向用手指力推閥頁，看能否打開，打開即防火無效）。煙道防火止回閥的溫控件盡量采用標(biāo)準(zhǔn)熔點(diǎn)的熔斷件，反應(yīng)靈敏，溫控更準(zhǔn)確。在200Pa背壓下，閥門漏風(fēng)量小于2m3/h；油煙機(jī)止回閥閥門的開啟動(dòng)壓力不大于10Pa，開啟角度不小于45。油煙機(jī)止回閥工作原理與升降式油煙機(jī)止回閥相似。</p><div
