渝北推薦通風管配件廠家

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。渝北通風管配件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，則通風管配件起到(dao)了(le)重(zhong)要的(de)(de)作用(yong)。防(fang)(fang)火(huo)閥的(de)(de)結構(gou)(gou)和(he)工作原理,防(fang)(fang)火(huo)閥主要由閥體和(he)執行機構(gou)(gou)組(zu)(zu)成。閥體由殼體、法蘭、葉片(pian)及(ji)葉片(pian)聯動(dong)(dong)機構(gou)(gou)等組(zu)(zu)成。執行機構(gou)(gou)由外殼、葉片(pian)調節機構(gou)(gou)、離(li)合(he)器(qi)(qi)、溫度熔斷器(qi)(qi)等組(zu)(zu)成。防(fang)(fang)火(huo)閥的(de)(de)執行機構(gou)(gou)是通過(guo)金屬易熔片(pian)和(he)離(li)合(he)器(qi)(qi)機構(gou)(gou)來控制葉片(pian)的(de)(de)轉動(dong)(dong)。
