防火閥的結(jié)構(gòu)和工作原理：防火閥是用來阻斷火災(zāi)區(qū)的煙氣及火焰通過，并在一定時(shí)間內(nèi)能滿足耐火穩(wěn)定性和耐火完整性要求的閥門。為了將火災(zāi)引起的損失減小到較低程度，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(fēng)、空調(diào)及排煙系統(tǒng)中的合適設(shè)置則起到了重要的作用。 </p> <p> 防火閥的結(jié)構(gòu)和工作原理：防火閥主要由閥體和執(zhí)行機(jī)構(gòu)組成。閥體由殼體、法蘭、葉片及葉片聯(lián)動(dòng)機(jī)構(gòu)等組成。執(zhí)行機(jī)構(gòu)由外殼、葉片調(diào)節(jié)機(jī)構(gòu)、離合器、溫度熔斷器等組成。防火閥的執(zhí)行機(jī)構(gòu)式通過金屬易熔片和離合器機(jī)構(gòu)來控制葉片的轉(zhuǎn)動(dòng)。
