摘要

This experiment used instantaneous flow generator drain away water on 34-layer tower.Investigate the different drainage pressure in each stack drainage system, explore the relationship between the pressure and flow rate, and confirm the corresponding drainage capacity.Analyze from multiple perspectives to provide reference for engineering application.The results show that: the drainage capacity (when the arranging diameter of the vent is the same) is main and secondary loop vent stack system ＞ self-circulating loop vent stack system ＞ self-circulating specific vent stack system, and DN110mm × DN110mm ＞DN125mm × DN110mm in each system; And the drainage capacity of the three drainage systems is significantly less than the maximum design fiow capacity value of building water supply and drainage design specifications (GB50015-2009).
