Fig. 1 is the structural representation that a kind of permanent low pressure of the utility model spurts gas extinguishing system.
Fig. 2 is the structural representation that a kind of permanent low pressure of the utility model spurts another embodiment of gas extinguishing system.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment 1
Referring to Fig. 1, what is provided in figure is that a kind of permanent low pressure spurts gas extinguishing system 100, including at least one receiving is gone out
It is starter 130 that the extinguishing chemical bottle 110 of fiery agent, container value 120, the control container valve 120 of control extinguishing chemical release are opened, aobvious
Show the pressure gauge 140 of extinguishing agent pressure in extinguishing chemical bottle, container value 120 is arranged on the bottle mouth position of extinguishing chemical bottle 110, starter
130th, pressure gauge 140 is connected with container value 120；The pipeline 150 of pressure conveying extinguishing agent is connected with the side of container value 120, is managed
The end of road 150 is provided with least one nozzle 151 for being used to spurt extinguishing chemical；It is provided between container value 120 and nozzle 151
Pressure reducing orifice 152, when the water of flowing passes through pressure reducing orifice 152, due to the diminution in aperture, local drag losses, depressurizing
Pressure drop is produced at hole, so as to meet the needs of the outlet pressure of fire extinguishing system and flow.
Constant decompressor 153 is provided between pressure reducing orifice 152 and nozzle 151, constant decompressor 153 is one
Pressure-reducing valve；Constant 153 constant secondary pressure of decompressor, output relatively low pressure to nozzle 151.Constant decompressor 153 is set
Before nozzle 151, when not in use, do not connected with gases at high pressure, normality not pressure-bearing, therefore the functional fault wind caused by access times
Danger is zero, can online dismantle, overhauls and change.Constant decompressor 153 may be provided in guard plot, in furred ceiling,
Concealed installation, the visual effect after installation under furred ceiling is as the gas nozzle of routine.
Starter 130 is that solenoid electric valve or hand push button are controlled, and solenoid electric valve is connected with fire alarm system；
Safety pin is provided with starter, safety pin interlocks with fire alarm system.It is provided with and raises one's voice at the middle part of extinguishing chemical bottle 110
Device 160, the input of loudspeaker 160 are connected with fire alarm system.
Dismountable anti-poison respirator 170 is provided with the bottom of extinguishing chemical bottle 110, the bottom of extinguishing chemical bottle 110 is provided with concave arc
