预作用自动喷水灭火系统控制原理解析

Analysis of Control Principle of Preaction Sprinkler System

《自动喷水灭火系统设计规范》(GB 50084—2017)和《火灾自动报警系统设计规范》(GB 50116—2013)对预作用自动喷水灭火系统的系统控制均有相应的要求,但由于规范编制的时间以及不同专业间术语含义不同,容易造成误解。依据两本规范并结合工程实际,对预作用系统的消防水泵和预作用装置控制原理进行了解析。同时为便于系统地理解预作用系统的控制,以"有增压稳压设施的临时高压预作用系统"为例,编制了"预作用系统控制要求"表格,供设计同仁参考,该表既可作为设计要点和校审重点,也可作为专业间互提资料清单。

Both Code for Design of Sprinkler Systems( GB 50084-2017) and Code for Design of Automatic Fire Alarm System( GB 50116-2013) had corresponding requirements for controlling principles of preaction sprinkler system. However,it was easy to cause misunderstanding due to the time for the preparation of the code and the different meanings of different professional terms. Based on the two codes and design practice,this paper analyzed the control principle of fire pump and preaction device in the system. At the same time,in order to understand the control of preaction sprinkler system,taking"temporary high pressure preaction sprinkler system with pressure-increasing and stabilizing facilities"as an example,the table of"control requirements for preaction sprinkler system"was compiled for reference of the design colleagues. The table could be used both as design point and review point and as the list of inter-professional information.
