Embodiment：A kind of fire-fighting spraying alarm system, as shown in Figure 1, including detection device 1, spray pipe network 2, fire extinguishing dress
3, water transfer pipe network 4, warning device 5, fire alarm control unit 6 and feed cistern 7 are set, detection device 1 is set as end water testing device
Or testing valve of water, it is connected to the end of spray pipe network 2, for being monitored and detecting to whole system, prevents wherein a certain ring
Damaging and causing to occur normally put out a fire when fire occur in section；Extinguishing device 3 includes the first letter being connected on spray pipe network 2
Number valve 31, water flow indicator 32 and multiple closed nozzles 33, the distance between adjacent two closed nozzle 33 are 2.5-3.5 meters, this
The setting of sample can effectively control the region that fire occurs.
One end of water transfer pipe network 4 is connected to spray pipe network 2, and the other end is connected to feed cistern 7, will according to the needs of construction
Warning device 5 is connected in position of the water transfer pipe network 4 at 215-20 meters of spray pipe network, and fire is reached so as to shorten fire water supply
The time at scene, it can put out a fire as early as possible, eliminate initial fire disaster as early as possible, substantially increase security performance.
As shown in Figure 1, fire alarm control unit 6 is connected to by electric wire between extinguishing device 3 and warning device 5, work as hair
When feelings of lighting a fire, the first signal valve 31 and water flow indicator 32 transmit a signal to fire alarm control unit 6, fire alarm control unit
6 control warning devices 5 start, and so that it is supplied water to water transfer pipe network 4 and spray pipe network 2, to put out a fire by extinguishing device 3.
Warning device 5 is set as wet alarm valve, second signal valve 51 is connected with below wet alarm valve, for receiving
The signal sent out from fire alarm control unit 6, draws water to start fire pump.The side of wet alarm valve is connected with one
To pressure gauge 52, for detecting the pressure balance inside wet alarm valve.The other side of wet alarm valve is connected with drain valve 53
With pet valve 54, the setting of drain valve 53 is endangered for the water in automatic discharge conduit to avoid caused by icing；Experiment
The setting of valve 54, for detecting wet alarm valve whether being capable of normal operation.
As shown in Figure 1, the position on wet alarm valve with 54 homonymy of drain valve 53 and pet valve is also associated with from the bottom to top
Flow controller 55, delayer 56, pressure switch 57 and warning water system 58, when closed nozzle 33 start water spray when, wet alarm valve by
In hydraulic pressure variation and moment opens, flow initially enters in delayer, and the water entered in delayer at this time is seldom, and water can be from
Flow controller 55 below is discharged, and will not enter in warning water system 58 or pressure switch 57, avoid false alarm.
When a fire, the heat-sensitive element on closed nozzle 33 experiences the variation of temperature, at this time heat-sensitive element
