1、排煙管宜采用鋼管或鑄鐵管。當(dāng)采用焊接鋼管時(shí)，其壁厚應(yīng)大于3mm；管道連接宜采用焊接。當(dāng)采用法蘭連接時(shí)，法蘭面應(yīng)平整，并應(yīng)有密封槽；法蘭之間應(yīng)襯墊耐熱膠墊。 </p> <p> 2、埋設(shè)于混凝土內(nèi)的鑄鐵排煙管，宜采用法蘭連接。 </p> <p> 3、排煙管應(yīng)沿軸線方向設(shè)置熱脹補(bǔ)償器。單向套管伸縮節(jié)應(yīng)與前后排煙管同心，文成通風(fēng)管道。柴油機(jī)排煙管與排煙總管的連接段應(yīng)有緩沖設(shè)施。 </p> <p> 4、排煙管的安裝，應(yīng)符合下列規(guī)定： </p> <p> （1）坡度應(yīng)大子0.5％，文成通風(fēng)管道，放水閥應(yīng)設(shè)在比較低處； </p> <p> （2）清掃孔堵板應(yīng)有耐熱墊層，并固定嚴(yán)密； </p> <p> （3）當(dāng)排煙管穿越隔墻時(shí)，其周圍空隙應(yīng)采用石棉繩填充密實(shí)； </p> <p> （4）排煙管與排煙道連接處，文成通風(fēng)管道，應(yīng)預(yù)埋帶有法蘭及密閉翼環(huán)的密閉穿墻短管。 </p> <p> （5）排煙管的地面出口端應(yīng)設(shè)防雨帽；在伸出地面150～200mm處，應(yīng)采取防止排煙管堵塞的措施。 </p> <p> <br /> 通風(fēng)管道都有哪幾種？文成通風(fēng)管道</p><div

</p> <p> 通風(fēng)管道內(nèi)風(fēng)速及風(fēng)量的測(cè)定，是通過(guò)測(cè)量壓力換算得到。測(cè)得管道中氣體的真實(shí)壓力值，除了正確使用測(cè)壓儀器外，合理選擇測(cè)量斷面、減少氣流擾動(dòng)對(duì)測(cè)量結(jié)果的影響很大。測(cè)量斷面應(yīng)盡量選擇在氣流平穩(wěn)的直管段上。測(cè)量斷面設(shè)在彎頭、三通等異形部件前面(相對(duì)氣流流動(dòng)方向)時(shí)，距這些部件的距離應(yīng)大于2倍管道直徑。當(dāng)測(cè)量斷面設(shè)在上述部件后面時(shí)，距這些部件的距離應(yīng)大于4～5倍管道直徑。當(dāng)測(cè)試現(xiàn)場(chǎng)難于滿足要求時(shí)，為減少誤差可適當(dāng)增加測(cè)點(diǎn)。但是，測(cè)量斷面位置距異形部件的**小距離至少是管道直徑的1.5倍。 </p> <p> <p> (二)測(cè)試孔和測(cè)定點(diǎn) </p> <p> 由于速度分布的不均勻性，壓力分布也是不均勻的。因此，必須在同一斷面上多點(diǎn)測(cè)量，然后求出該斷面的平均值。 </p> <p> 1圓形風(fēng)道 </p> <p> 在同一斷面設(shè)置兩個(gè)彼此垂直的測(cè)孔，并將管道斷面分成一定數(shù)量的等面積同心環(huán)，對(duì)于圓形風(fēng)道，測(cè)點(diǎn)越多，測(cè)量精度越高。 </p> <p> <br /> </p> 三門通風(fēng)管道工程地下室通風(fēng)管道有什么作用？</p><div style="width:100%;text-align:
