摘要

This experiment uses instantaneous flow generator drain away water on 34-floor tower.Investigate the different drainage pressure in each specific vent stack system, explore the relationship between the pressure and flow rate, and confirm the corresponding drainage capacity.The results show that: when using instantaneous flow, the maximum positive and negative pressure occurs in the intermediate floor of specific vent stack system.Compared with the maximum standard capacity value of building water supply and drainage design specifications (GB50015-2009), it is found that when the joining pipe setting with the same mode, the drainage capacity of instantaneous flow testing (joining pipe is connected in each floor) is DN110mm × DN110mm＞ DN125mm × DN110mm＞ DN110mm × DN75mm, when joining pipe is connected in each two floors, the drainage capacity of instantaneous flow testing is DN110mm ×DN110mm＞ DN110mm × DN75mm＞ DN125mm × DN110mm.
