摘要

阐述了目前自喷系统最不利喷头处压力取值缺乏科学性的现状。针对这一问题,举例探索了自喷系统作用面积内所有喷头的流量分配关系,再按作用面积内所有喷头平均喷水强度等于规范所规定的最低值计算得出最不利喷头压力。提出的根据作用面积内所有喷头流量配比关系计算得出最不利喷头处压力的方法既满足规范要求又实现了经济节能。
        Current situation which the value of the most unfavorable sprinkler pressure in automatic sprinkler system lack of scientificity was stated.In order to solve this problem,the flow distribution relationship of all sprinklers in area of sprinkler operation was illustrated and explored.And then,the most unfavorable sprinkler pressure was calculated according to the average water spraying intensity of all sprinklers in area of sprinkler operation equaling the minimum value the code stipulated.The method that calculating the most unfavorable sprinkler pressure on basis of the flow distribution relationship of all sprinklers in area of sprinkler operation met the requirements of the code and achieved the economy and energy saving,which had very strong practicability and popularization.
