燃氣熱(re)水器(qi)點火原理

家用燃氣熱(re)水(shui)器(qi)使用方(fang)便(bian),現在(zai)已經進入千家萬戶。燃氣熱(re)水(shui)氣的(de)基本原理(li)是利用水(shui)流流過細小的(de)管道，在(zai)管道下面(mian)有噴火嘴，用來加熱(re)自(zi)來水(shui)，由于(yu)加熱(re)的(de)面(mian)積大，細小，所(suo)以水(shui)很快被煮成高溫的(de)水(shui)。

燃氣熱水器(qi)(qi)點(dian)(dian)火(huo)(huo)(huo)機構由(you)點(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)、點(dian)(dian)火(huo)(huo)(huo)檢測、電(dian)(dian)(dian)(dian)磁閥、水壓(ya)開(kai)(kai)關等組成，當打(da)開(kai)(kai)水龍頭時，水流流過管道，在水閥的壓(ya)力(li)下，水壓(ya)開(kai)(kai)關被頂(ding)開(kai)(kai)，電(dian)(dian)(dian)(dian)池經電(dian)(dian)(dian)(dian)源開(kai)(kai)關、水壓(ya)開(kai)(kai)關加(jia)到(dao)點(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)，點(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)開(kai)(kai)始(shi)(shi)點(dian)(dian)火(huo)(huo)(huo)，同(tong)時煤氣電(dian)(dian)(dian)(dian)磁閥打(da)開(kai)(kai)，煤氣從噴火(huo)(huo)(huo)嘴液(ye)出，遇到(dao)點(dian)(dian)火(huo)(huo)(huo)器(qi)(qi)的高(gao)壓(ya)電(dian)(dian)(dian)(dian)火(huo)(huo)(huo)花開(kai)(kai)始(shi)(shi)燃燒(shao)，點(dian)(dian)火(huo)(huo)(huo)檢測電(dian)(dian)(dian)(dian)路檢測到(dao)火(huo)(huo)(huo)苗后，才停止點(dian)(dian)火(huo)(huo)(huo)。
