通风管道工程安(an)装(zhuang)(zhuang)有(you)哪些要点?通(tong)风管(guan)(guan)(guan)(guan)道是用于工(gong)业生(sheng)产(chan)和(he)工(gong)业建筑中(zhong)(zhong)自然通(tong)风、通(tong)风工(gong)程的(de)(de)金属或复合(he)管(guan)(guan)(guan)(guan)道，是室内通(tong)风，可降(jiang)﷽低城市基(ji)础设(she)施中(zhong)(zhong)有(you)害(hai)物(wu)质的(de)(de)浓度(du)。关于通(tong)风管(guan)(guan)(guan)(guan)道工(gong)程安(an)装(zhuang)(zhuang)要点，下面就为大家简单介(jie)绍(shao)一下。在安(an)装(zhuang)(zhuang)通(tong)风管(guan)(guan)(guan)(guan)道前(qian)，需要对货物(wu)进行仔细(xi)检(jian)查，核(he)实是否(fou)有(you)合(he)格证和(he)产(chan)品说明书(shu)建立原始恒压(ya)(ya)条件，产(chan)品密封件是否(fou)完好，外观(guan)是否(fou)无(wu)效。当密封损(sun)坏(huai)，原固定压(ya)(ya)力与(yu)(yu)工(gong)程设(she)计压(ya)(ya)力不符时，应重复进行抗压(ya)(ya)强度(du)和(he)气密性试验。在整个安(an)装(zhuang)(zhuang)过(guo)(guo)程中(zhong)(zhong)使(shi)用安(an)全(quan)系数非常(chang)方(fang)便，避免了(le)安(an)装(zhuang)(zhuang)后不能使(shi)用。安(an)装(zhuang)(zhuang)安(an)全(quan)阀并与(yu)(yu)机械设(she)备和(he)管(guan)(guan)(guan)(guan)道钻孔(kong)焊(han)接(jie)连(lian)接(jie)时，通(tong)风管(guan)(guan)(guan)(guan)道图(tu)的(de)(de)孔(kong)径应与(yu)(yu)安(an)全(quan)阀外径相同。短法(fa)兰管(guan)(guan)(guan)(guan)焊(han)接(jie)采用环法(fa)兰安(an)全(quan)阀，钻孔(kong)后长度(du)不得超过(guo)(guo)120mm。
