消防给水系统中阀门和管网设置对系统安全可靠性的影响

Influence of Valve and Pipe Network Setting on Safety and Reliability of Fire Water Supply System

消防给水工程按规范设计、施工图审查等建设环节投入运行后,仍然常出现发生火灾时消防给水系统无法正常供水灭火的尴尬局面。该文通过分析消防给水系统不合理设置阀门和管网的几个典型问题对系统安全可靠性的影响,提出了在设计阶段应充分考虑超压泄压阀可靠性、管网设置维护便利性等对系统安全可靠性的影响,并针对典型问题给出了相应的处置措施,可供相关工程参考。

After the fire water supply project is put into operation according to the standard design and construction drawing review,the problem often occurs that the fire water supply system cannot supply water normally and extinguish fire.This paper analyzed the influence of several typical problems in unreasonable setting of the valve and pipe network in fire water supply system on the system’s safety and reliability,proposing that the influence of the reliability of over-pressure decompression valve and the convenience of pipe network setting and maintenance on system safety and reliability should be fully considered in the design stage,with corresponding disposal measures for typical problems given,which can be used as reference for related engineering.
