防火閥是用來阻斷來自火災區的煙氣及火焰通過，并在一定時間內能滿足耐火穩定性和耐火完整性要求的閥門。沙坪壩電動防火閥為了將火災引起的損失減少到小程度，就必須采取有效的防火、防排煙措施，以控制火勢蔓延，而防火閥在通風、空調及防排煙系統中的合理設置，則電動防火閥起(qi)到了重(zhong)要的(de)(de)作用。防火閥(fa)的(de)(de)結構(gou)和(he)(he)工作原理,防火閥(fa)主要由(you)閥(fa)體(ti)(ti)和(he)(he)執(zhi)行(xing)(xing)機構(gou)組成。閥(fa)體(ti)(ti)由(you)殼(ke)體(ti)(ti)、法蘭、葉片(pian)及葉片(pian)聯動機構(gou)等組成。執(zhi)行(xing)(xing)機構(gou)由(you)外(wai)殼(ke)、葉片(pian)調節機構(gou)、離(li)合器(qi)、溫度(du)熔(rong)斷器(qi)等組成。防火閥(fa)的(de)(de)執(zhi)行(xing)(xing)機構(gou)是通過金屬易熔(rong)片(pian)和(he)(he)離(li)合器(qi)機構(gou)來(lai)控制葉片(pian)的(de)(de)轉動。
