Description
Technical field
The utility model relates to a kind of fire extinguishing system unit, and especially a kind of standby pressure type Fire-extinguishing System of Septenary-Fluorine Propane unit, belongs to fire-fighting equipment field.
Background technology
Heptafluoro-propane (HFC-227ea) extinguishing chemical is a kind of colorless and odorless, nonconducting gas at standard conditions, and its density is approximately 6 times of air, and be in a liquid state storage under pressure.This extinguishing chemical is clean medicament, not containing particle or oily residue after release, and does not pollute the environment and protected precision equipment.It has lower toxicity than Halon1301, often can be used for when design concentration is less than 9% the guard plot that someone works.Heptafluoro-propane has good extinguishing property, except chemically fire extinguishing is that except master, having cooling effect concurrently, be applicable to alternative existing haloalkane extinguishing system, is the comparatively ideal substitute of halon extinguishing agent simultaneously.
Heptafluoro-propane extinguishing mechanism has following three kinds of effects to form, Chemical Inhibition: during fire extinguishing, and gas heptafluoro-propane is met fire and easily decomposed, the active example produced in decomposable process, can living radical in inerting flame, blocks chain reaction during burning, making fray-out of flame, is its Main Function; Cooling effect: heptafluoro-propane extinguishing chemical is ejected in guard plot in liquid form, after ejection, liquid extinguisher gasifies rapidly, need to absorb a large amount of latent heat, the speed that the speed that this thing removes heat produces heat than incipient flame is fast, cool the gas of guard plot and flame periphery widely, be conducive to fire extinguishing; Smothering action: after being ejected into the liquid extinguisher gasification in guard plot, volume is comparatively large, reduces the concentration of oxygen in guard plot, thus reduces the speed of flame combustion, be conducive to fire extinguishing.
Heptafluoro-propane extinguishing chemical is because transfer pipeline is longer in course of conveying, and protection zone area is comparatively large, and cause insufficient pressure, extinguishing chemical can not be sent to rapidly, and extinguishing chemical sprays dynamics deficiency, and extinguishing effect is poor.
Utility model content
The utility model, just for the deficiency that prior art exists, provides a kind of standby pressure type Fire-extinguishing System of Septenary-Fluorine Propane unit.
For solving the problem, technical solution adopted in the utility model is as follows:
A kind of standby pressure type Fire-extinguishing System of Septenary-Fluorine Propane unit, comprise extinguishing chemical bottle group, nitrogen drives bottle group, nitrogen transfer pipeline assembly, tube connector one, tube connector two and check valve, extinguishing chemical bottle group top is provided with unidirectional pressure relieving valve, and drive bottle group to be connected with nitrogen transfer pipeline assembly, tube connector one and nitrogen successively, extinguishing chemical bottle group top is also provided with foamite container valve, and be connected with tube connector two and check valve successively, check valve is connected on afflux pipeline.
Further, described standby pressure type Fire-extinguishing System of Septenary-Fluorine Propane unit at least two group units shared.
Further, described nitrogen drives the nitrogen storage gas cylinder mounted in pairs of bottle group to use, and is connected on nitrogen transfer pipeline assembly by two tube connectors one.
Further.Described nitrogen drives and to be provided with primer liner between bottle group and lowly to let out on high envelope valve, and primer liner is connected to low letting out between high envelope valve.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
One described in the utility model is for pressure type Fire-extinguishing System of Septenary-Fluorine Propane unit, extinguishing chemical bottle group and nitrogen drive bottle group to be connected, nitrogen drives bottle group to provide larger pressure for extinguishing chemical bottle group, make extinguishing chemical can be transported to guard plot fire main effectively fast, fire extinguishing is swift in response, simple and compact equipment structure, facilitates accumulating I&M, floor space is little, saves construction area.
Accompanying drawing explanation
Fig. 1 is that one described in the utility model is for pressure type Fire-extinguishing System of Septenary-Fluorine Propane cell schematics;
Fig. 2 is the top view of Fig. 1.
Wherein, 1-extinguishing chemical bottle group, 2-nitrogen driving bottle group, 3-nitrogen transfer pipeline assembly, 4-tube connector one, 5-tube connector two, 6-check valve, 7-unidirectional pressure relieving valve, 8-foamite container valve, 9-primer liner, 10-low height of letting out seal valve.
Detailed description of the invention
Below in conjunction with specific embodiments content of the present utility model is described.
As shown in Figure 1 and Figure 2, described standby pressure type Fire-extinguishing System of Septenary-Fluorine Propane unit, comprise extinguishing chemical bottle group 1, nitrogen drives bottle group 2, nitrogen transfer pipeline assembly 3, tube connector 1, tube connector 25 and check valve 6, extinguishing chemical bottle group 1 top is provided with unidirectional pressure relieving valve 7, and drive bottle group 2 to be connected with nitrogen transfer pipeline assembly 3, tube connector 1 and nitrogen successively, extinguishing chemical bottle group 1 top is also provided with foamite container valve 8, and be connected with tube connector 25 and check valve 6 successively, check valve 6 is connected on afflux pipeline.
Extinguishing chemical bottle group 1 and nitrogen drive bottle group 2 to be connected, nitrogen drives bottle group 2 to be that extinguishing chemical bottle group carries 1 for larger pressure, make extinguishing chemical can be transported to guard plot fire main effectively fast, fire extinguishing is swift in response, simple and compact equipment structure, facilitate accumulating I&M, floor space is little, saves construction area.
Described standby pressure type Fire-extinguishing System of Septenary-Fluorine Propane unit at least two group units shared, effectively ensure the abundance of extinguishing chemical reserves, ensure that extinguishing chemical discharge pressure intensity, fire extinguishing system unit process is reliable rapidly.
