对干式消火栓系统设置要求的探讨

结合实际工作经验以及本人对干式消火栓系统条文的理解,探讨了干式消火栓系统的应用范围、系统配置和控制方式,并对部分规范条文提出了新的观点。建议在管道直径大于300mm的系统采用电动阀控制方式,其他情况采用电磁阀控制方式。在室内消火栓数量超过5只的干式消火栓系统中,系统管网应充有一定压力的气体,并设定低压压力报警装置,用于监测系统渗漏,同时建议增加预作用阀组控制方式。

REQUIREMENTS DISCUSSION FOR THE DRY FIRE HYDRANT SYSTEM

Combined with personal practical work experience and my understanding of the provisions of the dry fire hydrant system,the application scope,system configuration and control mode of the dry fire hydrant system are discussed,and put forward some new ideas on some normative provisions.Some suggestions are given,using electric valve in the system that the diameter of the pipeline is greater than 300mm,other places can use solenoid valve.In the fire hydrant system when the number of the fire hydrant more than 5,the system pipe network should be filled with a certain pressure gas,and set the low pressure alarm device,used to monitor the system leakage,and suggested to increase the pre-action valve group control.
