1、煤氣灶點火方(fang)式
煤氣灶(zao)(zao)的(de)點(dian)(dian)火(huo)(huo)方(fang)式(shi)主(zhu)要(yao)有電(dian)(dian)(dian)子(zi)脈沖點(dian)(dian)火(huo)(huo)和壓電(dian)(dian)(dian)陶瓷(ci)點(dian)(dian)火(huo)(huo)兩種(zhong),嵌入式(shi)灶(zao)(zao)多采(cai)用電(dian)(dian)(dian)子(zi)脈沖點(dian)(dian)火(huo)(huo)方(fang)式(shi),到某個位置就點(dian)(dian)著火(huo)(huo)了,其點(dian)(dian)火(huo)(huo)命(ming)中率(lv)高,一般是100%,但這種(zhong)方(fang)式(shi)需(xu)要(yao)換電(dian)(dian)(dian)池。而臺式(shi)灶(zao)(zao)多采(cai)用壓電(dian)(dian)(dian)陶瓷(ci)點(dian)(dian)火(huo)(huo)方(fang)式(shi),其點(dian)(dian)火(huo)(huo)的(de)成功率(lv)受環境濕度影響較大,點(dian)(dian)火(huo)(huo)的(de)時(shi)候(hou)需(xu)要(yao)按住開(kai)關才能打著火(huo)(huo)。
2、熄火方式
煤氣灶的安全使(shi)用需對其安裝熄(xi)火保護裝置(zhi),目前常用的熄(xi)火保護方式(shi)主要有熱(re)(re)敏式(shi)、熱(re)(re)電式(shi)和光電式(shi)三種。
熱敏式(shi)又稱雙金(jin)屬(shu)(shu)片(pian)式(shi),它利用(yong)雙金(jin)屬(shu)(shu)片(pian)在(zai)溫(wen)度作(zuo)用(yong)下(xia)膨(peng)脹彎(wan)曲(qu)(qu)的特性將雙金(jin)屬(shu)(shu)片(pian)作(zuo)為安(an)全保護裝(zhuang)置的傳(chuan)感器(qi),在(zai)溫(wen)度的作(zuo)用(yong)下(xia),膨(peng)脹系數(shu)大的金(jin)屬(shu)(shu)一面會向膨(peng)脹系數(shu)小的金(jin)屬(shu)(shu)一面彎(wan)曲(qu)(qu),當(dang)失去(qu)溫(wen)度時(shi),原(yuan)已膨(peng)脹彎(wan)曲(qu)(qu)的金(jin)屬(shu)(shu)又會慢(man)慢(man)恢(hui)復(fu)到原(yuan)。
