摘　　要：本文论证了如何根据最不利点处一只喷头动作时所测得的压力,来判定作用面积内所有喷头均动作时,自动喷水灭火系统的平均喷水强度、总流量和最不利点处喷头压力等主要水力性能是否可满足规范的要求.这种方法可用于中危险级自动喷水灭火系统的验收及防火检查.A method is proposed which is based on the waterhead measured at a weakest nozzle in operating to evaluate if the main hydraulic factors such as average sprinkling intensity of all the nozzles, overall discharge and waterhead at the pressure lowest point can meet the requirements of anti-fire codes while all the nozzles are acting over the active area of this automatic sprinkling system. This method can be used for acceptance and inspection of the anti-fire system of middle risk level.
