摘要
为了充分发挥消火栓的充实水柱有效长度,从计算公式入手,结合消火栓栓口的动压值,根据水力计算得出水枪充实水柱的长度,形成水枪的射流量和压力值的对照表。其次,从消火栓的保护半径公式着手,结合实际情况,在满足消防安全的情况下,给出2种计算依据和公式。
In order to give full play to the full length of the fire hydrant water column, this paper starts from the formula, combined withthe dynamic pressure of hydrant mouth, according to the hydraulic calculation of water gun full water column length, in contrast to thegun firing table flow and pressure value. Secondly, starting from the formula of radius of protection of the fire hydrant, combined with theactual situation, in order to meet the fire safety, gives 2 kinds of calculation basis and formula.
