Various improved procedures are improving the 5th security of diesel-driven generator factory building.
As shown in figure 1, being foam tank water-filled pipe adapter schematic diagram in foam-water deluge system in the prior art.Wherein 1
It is foam tank, 2 is deluge valves unit (normally closed), and 3 is Signal butterfly bamper (normally closed), and 4 is foam proportioning unit, and 5 is signal ball valve,
6 is hydraulic control valve, and 7 is check-valves.In the foam-water deluge system deluge valves unit is arranged on to the pipeline of foam tank water-filling
Afterwards, i.e., it is not with pressure in pipeline not water-filling, foam tank after deluge valves unit under non-fire condition；When fire occurs, deluge valves unit is beaten
Open in rear pipeline water-filling and to water-filling exruded foams liquid in foam tank.But combustible combustion speed is fast, coverage is wide, above-mentioned
The existing fire-fighting system arrangement reaction time is more long, foam-water deluge system is sprayed foam in time in fire
Liquid, so that reaction speed is slower, it is impossible to reduce the extent of injury that fire causes as far as possible.
Utility model content
The purpose of this utility model is directed to the 5th diesel-driven generator factory building foam-water deluge system, there is provided one kind contracting
Foam solution sprays the improved procedure of time in short foam-water deluge system, foam tank is in band pressure condition, and fire can when occurring
The step of reducing deluge valves unit opening backward foam tank water-filling, shortens SRT, in time the exruded foams from foam tank
Liquid, reduces the extent of injury that fire causes.
The utility model provides a kind of foam tank extinguishing device, and described device includes foam tank, deluge valves unit, signal butterfly
Valve, foam proportioning unit, signal ball valve, hydraulic control valve, check-valves, the water inlet of the foam tank are connected by pipeline
One one end of signal ball valve, the other end of the signal ball valve is directly connected to outside fire chief road by pipeline.
Further, foam tank extinguishing device as described above, the Signal butterfly bamper has two, and one of signal butterfly
Together with valve, the deluge valves unit and another Signal butterfly bamper are sequentially connected in series by pipeline, one of Signal butterfly bamper is straight
The deluge valves unit front end is connect in succession, and the fire water that described another Signal butterfly bamper connects the foam proportioning unit enters
Mouthful.
Further, foam tank extinguishing device as described above, between the foam tank and the foam proportioning unit
It is sequentially connected in series another signal ball valve and the hydraulic control valve, check-valves.
Further, foam tank extinguishing device as described above, the outside spray of outlet connection of the foam proportioning unit
Drench point.
Further, between foam tank extinguishing device as described above, the foam tank and deluge valves unit are arranged in fire-fighting equipment
It is interior.
Effect of the present utility model is：Foam tank is in band pressure condition, fire can reduce deluge valves unit opening when occurring after
The step of to foam tank water-filling, shorten SRT, in time the exruded foams liquid from foam tank, reduce the danger that fire causes
Evil degree.
Brief description of the drawings
Accompanying drawing 1 is original foam tank water-filled pipe adapter figure in foam-water deluge system；
Accompanying drawing 2 is foam tank water-filled pipe adapter figure of the present utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Fig. 21 is foam tank, 2 is deluge valves unit (normally closed), and 3 is Signal butterfly bamper (normally closed), and 4 is mixed for froth ratio
Attach together and put, 5 is signal ball valve, and 6 is hydraulic control valve, and 7 is check-valves.The water inlet of the foam tank connects one by pipeline
One end of signal ball valve, the other end of the signal ball valve is directly connected to outside fire chief road by pipeline.
The Signal butterfly bamper has two, and one of Signal butterfly bamper, the deluge valves unit and another Signal butterfly bamper
It is sequentially connected in series together by pipeline, one of Signal butterfly bamper is directly connected to the deluge valves unit front end, described another
Individual Signal butterfly bamper connects the fire-fighting water inlet of the foam proportioning unit.
Another signal ball valve and the waterpower are sequentially connected in series between the foam tank and the foam proportioning unit
Control valve, check-valves.The outside spray point of outlet connection of the foam proportioning unit.
Before the foam tank inlet pipeline drawn from fire chief road is moved to deluge valves unit by the utility model, make foam tank
In band pressure condition.Fire can reduce deluge valves unit opening backward foam tank water-filling when occurring the step of, when shortening system response
Between, the exruded foams liquid from foam tank, reduces the extent of injury that fire causes in time.
The utility model uses foam-water deluge system for the region that diesel oil, lubricating oil are covered, and foam tank, drench with rain valve
It is interior that the fire-fighting equipments such as group are arranged in fire-fighting equipment.
Obviously, those skilled in the art can carry out various changes and modification without deviating from this practicality to the utility model
New spirit and scope.So, if belonging to the utility model claim to these modifications of the present utility model and modification
And its within the scope of equivalent technology, then the utility model is also intended to comprising these changes and modification.
