【摘要】：在34层高度的试验塔上,首次采用定流量和瞬间流合流排水方式,瞬间流发生器定为3个,考察定流量排水选择的不同流量及其在不同排水系统中所产生的压力,探究压力与流量之间的关系,得出合流制排水方式下系统相应的排水能力,并进行多角度分析比较,由于管道系统内流量在大部分时间内都是一个定值,所以采用的判定标准为定流量标准。结果表明:DN110×DN110专用通气(结合管每层接)系统的排水能力明显优于DN110伸顶通气系统,且整个管道系统内的压力波动也明显小于DN110伸顶通气系统;DN110伸顶通气系统的排水能力略大于我国《建筑给水排水设计规范》(GB 50015—2009)中相应最大设计排水能力值,而DN110×DN110专用通气(结合管每层接)系统排水能力则略小于其相应的最大设计排水能力值。
[Abstract]:In the test tower of 34-story height, the combined flow drainage mode of constant flow and instantaneous flow is adopted for the first time, and the instantaneous flow generator is set as three. The different flow rate and the pressure produced in different drainage system are investigated.By exploring the relationship between pressure and flow rate, the corresponding drainage capacity of the system under the combined drainage mode is obtained, and the multi-angle analysis and comparison are carried out. Because the flow rate in the pipeline system is a fixed value for most of the time,Therefore, the decision standard is a constant flow standard.The results show that the drainage capacity of the special ventilation system of 1: DN110 脳 DN110 is obviously better than that of the DN110 extended roof ventilation system.And the pressure fluctuation in the whole pipeline system is obviously smaller than the corresponding maximum design drainage capacity value of the DN110 extended ceiling ventilation system (DN110), which is slightly larger than the corresponding maximum design capacity in the Building Water supply and drainage Design Code of China (GB50015-2009).However, the drainage capacity of DN110 脳 DN110 special ventilation system is slightly less than the corresponding maximum design drainage capacity.
