摘要
本文通过定量分析,从理论上证明了高层民用建筑室内消火栓口处应保持0.25～0.30MPa的剩余水压是操作者力所能及和灭火要求的必要条件,该水压取值范围也是孔板选型得以简化的基础数据。只要按需求直接选用本文的四组数据中一组,再进行典型竖管的阻力计算,查阅表3就可直接进行孔板选型,同时兼顾到减少孔板型号的要求。
There has been demonstrated theoretically through quantitative analysis that for the indoor fire-hydrants installed in high rise civil building a free water head of 0. 25 to 0. 30 MPa will be necessary for the operation. This range of water pressures are also the basic data to simplify the orifice selection. The selection of orifices will be welldone direct according to one of the four sets of data offered in this paper and the typical hydraulic calculation of vertical pipes.
