本文概要地介绍自动喷水灭火系统的喷头布置要求,以及系统的主要组件的动作基本原理。一、喷头布置的要求如下:1.合理确定喷头间距。火灾实例和试验证明,合理布置喷头间距,对迅速有效地扑灭火灾有很大的关系。因此,在设计中应根据建筑物、构筑物划分的危险等级,合理确定喷头的间距,并应符合40页表1的要求。2.喷头(吊顶型喷头除外)溅水盘与吊顶、楼板、屋面板的距离,不宜小于7.5厘米,也不宜大于15厘
This article provides an overview of sprinkler arrangements for sprinkler systems and the basic principles of operation of the major components of the system. First, the nozzle layout requirements are as follows: 1. Reasonably determine the nozzle spacing. Fire examples and tests have shown that a reasonable arrangement of nozzle spacing, the rapid and effective fire extinguishing have a great relationship. Therefore, the design should be based on the classification of buildings, structures, hazard levels, a reasonable determination of nozzle spacing, and should meet the requirements of Table 1 on page 40. 2. Sprinklers (other than ceiling-type sprinkler) Splashers and suspended ceiling, floor, roof distance, not less than 7.5 cm, not more than 15%
