防(fang)(fang)火(huo)(huo)(huo)(huo)(huo)閥(fa)是用來阻斷(duan)來自(zi)火(huo)(huo)(huo)(huo)(huo)災區(qu)的(de)煙氣及(ji)火(huo)(huo)(huo)(huo)(huo)焰通過，并在一定(ding)時間內能滿足耐火(huo)(huo)(huo)(huo)(huo)穩(wen)定(ding)性(xing)和(he)(he)耐火(huo)(huo)(huo)(huo)(huo)完整性(xing)要(yao)求(qiu)的(de)閥(fa)門。為了將火(huo)(huo)(huo)(huo)(huo)災引起的(de)損失減少到小程度，就必須采取有效(xiao)的(de)防(fang)(fang)火(huo)(huo)(huo)(huo)(huo)、防(fang)(fang)排煙措(cuo)施(shi)，以(yi)控制火(huo)(huo)(huo)(huo)(huo)勢蔓延，而防(fang)(fang)火(huo)(huo)(huo)(huo)(huo)閥(fa)在通風、空(kong)調及(ji)防(fang)(fang)排煙系統中的(de)合理設置，則起到了重要(yao)的(de)作用。防(fang)(fang)火(huo)(huo)(huo)(huo)(huo)閥(fa)的(de)結構(gou)和(he)(he)工作原理,防(fang)(fang)火(huo)(huo)(huo)(huo)(huo)閥(fa)主要(yao)由(you)閥(fa)體(ti)(ti)和(he)(he)執行(xing)機(ji)(ji)構(gou)組成。閥(fa)體(ti)(ti)由(you)殼體(ti)(ti)、法蘭、葉片及(ji)葉片聯動(dong)機(ji)(ji)構(gou)等(deng)組成。執行(xing)機(ji)(ji)構(gou)由(you)外殼、葉片調節機(ji)(ji)構(gou)、離合器(qi)、溫度熔(rong)斷(duan)器(qi)等(deng)組成。防(fang)(fang)火(huo)(huo)(huo)(huo)(huo)閥(fa)的(de)執行(xing)機(ji)(ji)構(gou)是通過金屬(shu)易(yi)熔(rong)片和(he)(he)離合器(qi)機(ji)(ji)構(gou)來控制葉片的(de)轉動(dong)。

1，通(tong)風(feng)(feng)風(feng)(feng)管(guan)安裝在(zai)支(zhi)架上(shang)，應(ying)(ying)(ying)設(she)托(tuo)座。2，通(tong)風(feng)(feng)風(feng)(feng)管(guan)如(ru)有穿出(chu)屋面(mian)(mian)外部分，應(ying)(ying)(ying)設(she)置防雨罩(zhao)。3，通(tong)風(feng)(feng)風(feng)(feng)管(guan)采用(yong)(yong)無法蘭連時，接(jie)口處應(ying)(ying)(ying)嚴密牢固。通(tong)風(feng)(feng)風(feng)(feng)管(guan)連接(jie)兩平面(mian)(mian)應(ying)(ying)(ying)平直，不(bu)得錯位及扭(niu)曲。4，輸送易產生冷(leng)凝水(shui)的(de)通(tong)風(feng)(feng)風(feng)(feng)管(guan)，安裝應(ying)(ying)(ying)設(she)計(ji)坡度。通(tong)風(feng)(feng)風(feng)(feng)管(guan)底部不(bu)能有縱向的(de)接(jie)縫(feng)， 如(ru)必須有接(jie)縫(feng)，則應(ying)(ying)(ying)采用(yong)(yong)密封(feng)方式(shi)。通(tong)風(feng)(feng)管(guan)道安裝完畢后，應(ying)(ying)(ying)進行嚴密性(xing)試驗，如(ru)發現異常情(qing)況，通(tong)風(feng)(feng)管(guan)道的(de)制作、安裝、檢驗和(he)試驗，是一個連貫的(de)工程，做到(dao)安全適用(yong)(yong)，經濟合理，方便施工，確保通(tong)風(feng)(feng)管(guan)道的(de)工程質量。

風(feng)(feng)機(ji)(ji)(ji)(ji)分(fen)類可以(yi)(yi)按氣(qi)體流(liu)動(dong)的方向(xiang)(xiang)，分(fen)為(wei)離(li)(li)(li)心(xin)式、軸流(liu)式、斜流(liu)式和(he)(he)橫流(liu)式等類型。這種風(feng)(feng)機(ji)(ji)(ji)(ji)分(fen)類的機(ji)(ji)(ji)(ji)器有：離(li)(li)(li)心(xin)風(feng)(feng)機(ji)(ji)(ji)(ji)工作時，動(dong)力機(ji)(ji)(ji)(ji)(主(zhu)要是電(dian)動(dong)機(ji)(ji)(ji)(ji))驅動(dong)葉輪在(zai)蝸形機(ji)(ji)(ji)(ji)殼內旋轉(zhuan)，空氣(qi)經(jing)吸(xi)(xi)氣(qi)口(kou)從葉輪中心(xin)處吸(xi)(xi)入(ru)。由于葉片對氣(qi)體的動(dong)力作用(yong)(yong)，氣(qi)體壓力和(he)(he)速(su)度得(de)以(yi)(yi)提(ti)高，并在(zai)離(li)(li)(li)心(xin)力作用(yong)(yong)下沿著葉道甩向(xiang)(xiang)機(ji)(ji)(ji)(ji)殼，從排(pai)氣(qi)口(kou)排(pai)出。因(yin)氣(qi)體在(zai)葉輪內的流(liu)動(dong)主(zhu)要是在(zai)徑向(xiang)(xiang)平面內，故又稱(cheng)徑流(liu)風(feng)(feng)機(ji)(ji)(ji)(ji)。離(li)(li)(li)心(xin)風(feng)(feng)機(ji)(ji)(ji)(ji)主(zhu)要由葉輪和(he)(he)機(ji)(ji)(ji)(ji)殼組成，小型風(feng)(feng)機(ji)(ji)(ji)(ji)的葉輪直接(jie)裝在(zai)電(dian)動(dong)機(ji)(ji)(ji)(ji)上中、大型風(feng)(feng)機(ji)(ji)(ji)(ji)通過聯軸器或(huo)皮帶(dai)輪與(yu)電(dian)動(dong)機(ji)(ji)(ji)(ji)聯接(jie)。離(li)(li)(li)心(xin)風(feng)(feng)機(ji)(ji)(ji)(ji)一般(ban)為(wei)單側進氣(qi)，用(yong)(yong)單級葉輪；流(liu)量大的可雙(shuang)側進氣(qi)，用(yong)(yong)兩(liang)個背靠背的葉輪，又稱(cheng)為(wei)雙(shuang)吸(xi)(xi)式離(li)(li)(li)心(xin)風(feng)(feng)機(ji)(ji)(ji)(ji)。

在葉輪運轉初期及所有定期檢查的時候，只要一有機會，都必須檢查葉輪是否出現裂紋、磨損、積塵等缺陷。只要有可能，都必須使葉輪保持清潔狀態，并定期用鋼絲刷刷去上面的積塵和銹皮等，因為不銹鋼通風管道隨著運行時間的加長，這些灰塵由于不可能均勻地附著在葉輪上，而造成葉輪平衡破壞，以至引起轉子振動。葉輪只要進行了修理，就需要對其再作動平衡。如有條件，可以使用便攜試動平衡儀在現場進行平衡。在作動平衡之前，不銹鋼通風管道價格必(bi)須檢查(cha)所有緊(jin)定螺栓是否上(shang)緊(jin)。因為葉輪已(yi)(yi)經在不平(ping)衡狀(zhuang)態(tai)下運行了一段時間(jian)，這些螺栓可能已(yi)(yi)經松(song)動。
