建筑排水专用通气管下迂回侧排系统的研究
|
摘要
为了配合建筑造型的要求,打破传统的建筑排水专用通气系统型式,将通气管往下迂回后从侧面排出至室外。通过水力计算得到卫生器具水封刚好被破坏时的高空风压所对应的风速值,这为日后设计类似建筑排水透气系统提供了依据;同时将该系统延伸列举出几种在工程实践中可以应用的系统型式,即通气管下迂回单侧排放系统、通气管下迂回对向侧排系统、卫生间环形通气管下迂回系统。
To cooperate with architectural requirement,the traditional style of building drainage special ventilation system was transcended—the vent pipe was bent down and then exited from the sidewall. When the water seal of appliance was broken,wind speed was theoretically derived from the corresponding upper air pressure,this provided the bases for the design of similar building drainage ventilation systems in the future. Several derivatives of the system were provided for application in engineering practices,including special ventilation pipe downward circuitous and side-discharge,special ventilation pipe downward circuitous and opposite side-discharge,and downward circuitous annular ventilation pipe in toilet.
