Background
Automatic sprinkler systems were the first line of life for fire safety in existing buildings. The working principle of the existing automatic water spraying fire extinguishing system is that when a fire disaster occurs and the temperature rise meets the condition that a closed nozzle is opened, the closed nozzle starts spraying water. After water flows in the pipeline, the wet alarm valve is opened, the water is led to a channel of the hydraulic alarm bell after passing through the delayer, the water flow impacts the hydraulic alarm bell to generate an audible alarm signal, meanwhile, a pressure switch signal in front of the hydraulic alarm bell is transmitted to the fire pump control box, the fire pump is started to supply water to the pipe network in a pressurized mode, and the purpose of continuously and automatically spraying water to extinguish fire is achieved.
However, the existing automatic water spraying fire extinguishing system supplies water in a branch shape, and has the problem of low water supply reliability. For example, for a fire acceptance project, the following may occur: the tail end water testing device of the water spraying fire extinguishing system detects pressure water, and accords with acceptance indexes, but a certain position of the spraying pipe is blocked, the water supply of a pipeline at the rear end of the spraying pipe is insufficient in pressure, even the spraying pipe is seriously blocked, and the pipeline at the rear end is free of water.
When a fire disaster occurs in the project, the water spraying pressure of all the spray heads in the pipeline at the rear end of the blocked position is insufficient or no water is sprayed, so that the situation that the fire cannot be effectively extinguished is caused, and the serious consequence of fire spreading is caused. And under the condition that the water pressure of the nozzle is insufficient, the delayed start of the wet alarm valve can also occur, and the timely start of the fire pump is seriously influenced.
