建筑排水系统经常会遇到排水不畅,噪音污染,甚至向室内溢流污水,逸出臭气等问题。排水立管内气压波动是影响排水能力主要因素,设计一种迅速稳定管道压力波动的排水立管系统成为提高排水能力亟待解决的问题。提出了一种改进型的双孔排水立管系统即AB型双孔排水立管系统,描述了该系统的管件构造,分析了水流在该系统中的运行工况,认为AB型单立管系统排水性能良好,便于施工且节省安装空间,符合当前节能减排的国策,具有较高的应用价值。
Building drainage systems often encounter poor drainage, noise pollution, and even indoor overflow sewage, escape odor and other issues. The pressure fluctuation in the drainage riser is the main factor that affects the drainage capacity. It is an urgent problem to design a drainage riser system that can quickly and stably fluctuate the pressure of the pipeline. An improved two-hole drainage riser system, namely, the AB-type double-hole drainage riser system is proposed. The pipe structure of the system is described and the operating conditions of the water flow in the system are analyzed. It is considered that the AB single- Drainage performance is good, easy to install and save installation space, in line with the current national policy of energy-saving emission reduction, with high application value.
