但需做好正規白鐵風管以下幾點: 法蘭連接:為保證法蘭白鐵風管廠家接(jie)(jie)口嚴(yan)密(mi)性,法(fa)蘭之間(jian)應有(you)墊(dian)料(liao)(liao)。在(zai)(zai)無(wu)特(te)殊要(yao)求的(de)情(qing)況下(xia),法(fa)蘭墊(dian)料(liao)(liao)按(an)下(xia)表選(xuan)用(yong)(yong)(yong)(yong)。風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)排(pai)列無(wu)法(fa)蘭連(lian)(lian)接(jie)(jie) 抱(bao)箍(gu)(gu)式連(lian)(lian)接(jie)(jie):主(zhu)要(yao)用(yong)(yong)(yong)(yong)于(yu)鋼板圓(yuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)和(he)螺旋風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)連(lian)(lian)接(jie)(jie),先(xian)把每(mei)一(yi)管(guan)(guan)(guan)(guan)(guan)段的(de)兩(liang)(liang)端(duan)(duan)軋出鼓筋,并使其一(yi)端(duan)(duan)縮為小口。安裝時按(an)氣流方向把小口插(cha)(cha)入(ru)大口,外面用(yong)(yong)(yong)(yong)鋼制(zhi)(zhi)抱(bao)箍(gu)(gu)將(jiang)兩(liang)(liang)端(duan)(duan)的(de)鼓箍(gu)(gu)抱(bao)緊(jin)連(lian)(lian)接(jie)(jie),后用(yong)(yong)(yong)(yong)螺栓穿(chuan)在(zai)(zai)耳環中間(jian)固(gu)定擰緊(jin)。 插(cha)(cha)接(jie)(jie)式連(lian)(lian)接(jie)(jie):主(zhu)要(yao)用(yong)(yong)(yong)(yong)于(yu)矩形或圓(yuan)形風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)連(lian)(lian)接(jie)(jie)。先(xian)制(zhi)(zhi)作連(lian)(lian)接(jie)(jie)管(guan)(guan)(guan)(guan)(guan),然后插(cha)(cha)入(ru)兩(liang)(liang)側風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan),再用(yong)(yong)(yong)(yong)拉(la)鉚釘將(jiang)其緊(jin)密(mi)固(gu)定。 插(cha)(cha)條式連(lian)(lian)接(jie)(jie):主(zhu)要(yao)用(yong)(yong)(yong)(yong)于(yu)重慶矩形風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)加工成品的(de)連(lian)(lian)接(jie)(jie)。將(jiang)不同形式的(de)插(cha)(cha)條插(cha)(cha)入(ru)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)兩(liang)(liang)端(duan)(duan),然后壓實。 軟(ruan)(ruan)管(guan)(guan)(guan)(guan)(guan)式連(lian)(lian)接(jie)(jie):主(zhu)要(yao)用(yong)(yong)(yong)(yong)于(yu)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)與部(bu)件(jian)(如散(san)熱器、靜壓箱側送風(feng)(feng)(feng)口等(deng))的(de)相(xiang)連(lian)(lian)。安裝時軟(ruan)(ruan)管(guan)(guan)(guan)(guan)(guan)兩(liang)(liang)端(duan)(duan)套在(zai)(zai)連(lian)(lian)接(jie)(jie)的(de)管(guan)(guan)(guan)(guan)(guan)外,然后用(yong)(yong)(yong)(yong)特(te)別軟(ruan)(ruan)的(de)卡箍(gu)(gu)把軟(ruan)(ruan)管(guan)(guan)(guan)(guan)(guan)箍(gu)(gu)緊(jin)。
凈化系統送回正規白鐵風管風管、中央空調通風管、工業送排風通風管、環保系統吸排風管、礦用抽放瓦斯管、礦用涂膠白鐵風管廠家布風筒(tong)等。通風管(guan)道為膠結料中堿玻璃(li)纖維為增強材(cai)(cai)料、加(jia)入(ru)填充材(cai)(cai)料和改性劑等所制成(cheng)的(de)一種管(guan)材(cai)(cai)。它(ta)具有(you)不燃燒、屬不燃材(cai)(cai)料A級,耐腐蝕、強度高和重量輕等特點。在建(jian)筑工(gong)程、地下工(gong)程及工(gong)業廠房(fang)的(de)通風中,它(ta)已經(jing)完(wan)全取代了(le)不耐燃的(de)有(you)機(ji)玻璃(li)鋼(gang)通風管(guan),并在逐(zhu)步取代防腐性能差的(de)鍍鋅鐵皮(pi)通風管(guan)。尤其是(shi)在濕度大的(de)地下工(gong)程和長江以南地區,它(ta)的(de)優越性更為顯著。
重要的鋅正規白鐵風管的化合物是氧化鋅,俗名叫“鋅白”,是著名的白色顏料,用來制造白色油漆等。在室溫下氧化白鐵風管廠家鋅是白(bai)色(se)(se)(se)的(de),受熱后卻會(hui)變(bian)成黃(huang)色(se)(se)(se),而再冷(leng)卻時,又重新變(bian)成白(bai)色(se)(se)(se)。現在,人們利用它的(de)這(zhe)個特(te)點,制成“變(bian)色(se)(se)(se)溫度(du)計(ji)”——用它顏色(se)(se)(se)的(de)變(bian)化來測(ce)量溫度(du)。
支吊架不得正規白鐵風管安裝在風口、閥門檢查孔處,以免妨礙操作。吊架不得直接吊在法蘭上。保溫風管不能直接與支白鐵風管廠家吊架(jia)(jia)接觸,應墊(dian)上堅固的(de)隔(ge)熱材(cai)料,其厚(hou)度與保溫風(feng)管(guan)厚(hou)度相同(tong),防止產生“冷橋(qiao)”。聚氯吞烯風(feng)管(guan)也與鋼(gang)板風(feng)管(guan)一(yi)(yi)樣(yang)采用(yong)支、吊托架(jia)(jia),但(dan)一(yi)(yi)般(ban)以吊架(jia)(jia)為主,支架(jia)(jia)間距按下表的(de)要(yao)求制作(zuo)安裝。
