摘要
分析了在作用面积内自动喷水系统的5种喷头的不同布置间距条件下系统的设计流量,设计流量为强度面积法计算的1.66～3.0倍,其比例参数可用于设计。此外,分析了高区为标准层、低区为带裙楼的公共设施层的商务写字楼和宾馆高层建筑自动喷水灭火系统的设计流量特点和常规选择消防主泵存在的问题,提出以低区工况选泵,按高区工况校核的选泵方法,并给出该法适用范围,同时介绍了水力报警阀、喷头作用水头和泄水装置设置的有关问题。
Design fluxes for the fire sprinkler system were counted with five kinds of arragement of the sprinkler in affective area, the design fluxes are 1.66～3.0 times more than that of theory and corresponging parameters may be applied to the practice. In addition, the characteristics of design fluxes for the fire sprinkler system in high rise building was analyzed and problem in ordinary selection of main fire pump comparing with these design fluxes was discussed.The problem raises due to selecting the fire pump on the basis of working condition in the down section of building. Then the suitable range to use this method was given.At the same time design of hydraulic alarm valve、the sprinkler acting pressure and the sluice pipe was introcluced.
