燃氣熱(re)水器點火(huo)原理

家用(yong)燃氣(qi)熱(re)(re)水(shui)(shui)器(qi)使用(yong)方便(bian),現在(zai)已經(jing)進入千家萬戶。燃氣(qi)熱(re)(re)水(shui)(shui)氣(qi)的基本原理是利用(yong)水(shui)(shui)流(liu)流(liu)過細小的管道，在(zai)管道下面有噴火(huo)嘴，用(yong)來加熱(re)(re)自來水(shui)(shui)，由于(yu)加熱(re)(re)的面積大，細小，所以水(shui)(shui)很快被煮成(cheng)高溫的水(shui)(shui)。

燃氣(qi)熱水(shui)(shui)器點(dian)(dian)火(huo)(huo)機(ji)構由點(dian)(dian)火(huo)(huo)器、點(dian)(dian)火(huo)(huo)檢測(ce)、電(dian)(dian)磁閥(fa)、水(shui)(shui)壓(ya)開(kai)(kai)(kai)關(guan)(guan)等組成，當打開(kai)(kai)(kai)水(shui)(shui)龍(long)頭(tou)時，水(shui)(shui)流流過管(guan)道，在水(shui)(shui)閥(fa)的壓(ya)力下，水(shui)(shui)壓(ya)開(kai)(kai)(kai)關(guan)(guan)被頂開(kai)(kai)(kai)，電(dian)(dian)池經電(dian)(dian)源開(kai)(kai)(kai)關(guan)(guan)、水(shui)(shui)壓(ya)開(kai)(kai)(kai)關(guan)(guan)加(jia)到點(dian)(dian)火(huo)(huo)器，點(dian)(dian)火(huo)(huo)器開(kai)(kai)(kai)始點(dian)(dian)火(huo)(huo)，同時煤氣(qi)電(dian)(dian)磁閥(fa)打開(kai)(kai)(kai)，煤氣(qi)從(cong)噴火(huo)(huo)嘴液出，遇到點(dian)(dian)火(huo)(huo)器的高壓(ya)電(dian)(dian)火(huo)(huo)花(hua)開(kai)(kai)(kai)始燃燒，點(dian)(dian)火(huo)(huo)檢測(ce)電(dian)(dian)路檢測(ce)到火(huo)(huo)苗后，才停(ting)止(zhi)點(dian)(dian)火(huo)(huo)。

以上是水氣聯動(dong)裝(zhuang)置(zhi)熱水器的(de)點火(huo)原理(li)，另一(yi)種(zhong)是采(cai)用(yong)霍爾傳(chuan)(chuan)感(gan)器感(gan)知水流,由微控制器根據傳(chuan)(chuan)感(gan)的(de)信號給出點火(huo)信號,以此系統(tong)替代傳(chuan)(chuan)統(tong)的(de)水氣聯動(dong)閥(fa)。
