在分析喷头布置基本原则的基础上,探讨理想状况下自动喷水灭火系统喷头的布置情况,根据《自动喷水灭火系统设计规范》计算了喷头的间距范围和有效保护半径,认为喷头的布置间距不是仅由喷水强度决定,而是喷水强度、工作压力、流量系数等参数共同作用的结果;喷头的不同布置形式决定了喷头与端墙的距离,在实际工程中应根据实际情况灵活布置喷头。
在分析噴頭佈置基本原則的基礎上,探討理想狀況下自動噴水滅火繫統噴頭的佈置情況,根據《自動噴水滅火繫統設計規範》計算瞭噴頭的間距範圍和有效保護半徑,認為噴頭的佈置間距不是僅由噴水彊度決定,而是噴水彊度、工作壓力、流量繫數等參數共同作用的結果;噴頭的不同佈置形式決定瞭噴頭與耑牆的距離,在實際工程中應根據實際情況靈活佈置噴頭。

Based on the distribution principle of sprinkler heads,an ideal distribution of automatic sprinklers is discussed.The spacing range and effective protection radius of sprinkler head is calculated ac-cording to Automatic Sprinkler System Design Specification.It is concluded that the spacing of sprinkler heads is jointly decided by spray strength,working pressure,flow coefficient,and that the distance from sprinkler head to the end wall is determined by the layout of sprinklers.It is thus recommended that the sprin-kler heads should be flexibly arranged in the project according to the circumstances.
