高层建筑消火栓前减压孔板计算探讨

Calculation of Pressure Reducing Orifice before the Hydrant in High Rise Building

本文结合实例对消火栓给水系统栓前减压孔板进行了计算与分析，认为减压计算应以水泵供水工况计算减压值和孔板型号，再以水箱供水工况进行校核，从而确定减压孔板型号，进而达到消火栓给水系统减压的目的。

Abstract The calculation of pressure reducing orifices placed before the hydrant is discussed and is pointed out that the results of pressure reducing calculation have to be checked by the working status of the water pump to determine the type of the orifice for the faire pressure balancing of the hydrant water system.
