浅论自动喷洒系统喷头的工作压力及喷头的水平布置间距

ON THE WORKING PRESSURE AND HORIZONTAL INTERVAL OF NOZZLES OF AN AUTOMATIC SPRINGLER SYSTEM

本文通过工程设计实践,提出:喷头的工作压力及喷头间的水平布置间距不应局限于"规范"的要求,应结合建筑结构的具体形式,选择适当的末端喷头工作压力,并充分利用喷淋系统管网各点的不同压力,合理地布置喷头水平间距。对一具体工程,除"规范"要求的喷水强度是一定值外,其它设计参数均是变量,均可根据实际工程的具体设置条件灵活运用。

With the experiences of engineering practice the author proposed that the workingpressure and horizontal interval of nozzles in a automatic sprinkler system could be selectedbeyond the restriction of current design standard. The watex head of the nozzle located at the en terminal of pipe have to be determined according to the practical form of building structure and the horizontal interval of nozzles be arranged on the basis of full use the pressure distribution through the sprinkler network. For a particular case of design,except that the spring intensity must be meet the requirements of design standard, all the other parameters would be determined in accordance with the concrete coditions of the project.
