Description
Technical field
The utility model relates to a kind of extinguishing device, and especially a kind of foam-water spray coupling extinguishing device belongs to the fire fighting device technical field.
Background technology
At present, adopt foam solution as the extinguishing device extinguishing chemical that puts out the category-B combustible liquid fire both at home and abroad usually.Understand according to the applicant, the fixed froth installation of implementing foam fire-fighting mainly contains two classes, and the one, fixed fixed froth installation, the 2nd, the small-sized fire-fighting equipment such as hand fire extinguisher.In use, the problem that the former exists is the corollary equipment complex structure, and bulky, the layman can't use; The shortcoming that the latter exists is that volume is little, and extinguishing chemical is few, can only use the of short duration several seconds, therefore is difficult to obtain desirable actual fire extinguishing effect.
Along with promulgation, the enforcement of China's " fire service law ", the fire-fighting of social all trades and professions consciousness improves constantly; Sustainable development of social economy makes needs the place of fire-fighting protection constantly to increase; As a result, people constantly increase and improve the demand and the requirement of fire product.For example A, the category-B that might take place to be caused by gasoline-like fuel such as subterranean tunnel, underground garage mixes the special place of fire, very need automatically foam to be mixed with water and effective attack time than the fire-fighting equipment of length.
Summary of the invention
The purpose of this utility model is: at the problem that existing fixed froth installation exists, proposes a kind of can automatically foam be mixed with water and effective attack time than length foam-water spray and use automatic fire extinguisher.
In order to reach above purpose, foam of the present utility model-water spray coupling automatic fire extinguisher comprises the sealed sprinkler head (9) of being with temperature sensor, connect the feed pipe (26) and the foam liquid tank (4) of sealed sprinkler head (9) by pipeline, be serially connected with wet alarm valve (20) and foam proportioner (19) in the described feed pipe (26), one outlet of described wet alarm valve (20) is by the pressure switch (41) in delayer (42) pressure relief pipe taking alarm (21), the Pressure Relief Valve (36) that is connected by this pressure switch (41) is connected in the control piper (37), the controlled termination control piper of foam solution control valve (14) (37) in foam liquid tank (4) exit, the outlet of foam solution control valve (14) connects foam proportioner (19).
Environment temperature in the utility model foam-water spray coupling automatic fire extinguisher protection zone is because the fire rising; reach the sealed sprinkler head operating temperature and shower nozzle is opened when spraying water; current are opened wet alarm valve; press water enters the warning pressure relief pipe; the pressure switch action; start fire pump, supply water to the system pipe network pressurization.Simultaneously, press water is opened Pressure Relief Valve, makes the press water pressure release in the control piper, and the foam solution control valve is opened automatically.Foam liquid tank is owing to pushed by the press water of foam tank supply channel, and capsule inner foam liquid is mixed through the foam solution control valve with from the water that main line enters foam proportioner, forms foam mixing liquid, via the sprinkler tip ejection of opening, puts out a fire.
This shows that the utility model science has solved the automatic mixed problem of foam and water dexterously, and, therefore need only the water source and fully can keep long effective attack time because the volume of foam liquid tank can design as required.Be applicable in the building and structures that the flammable liquid existence is arranged that water spray protection system can be installed, as: dangerous goods store, garage, hangar, parking lot, chemical plant, boiler room, petroleum chemical enterprise, smelter etc.In addition, to the category-A fire of common material, and the fire of material such as rubber, plastics, synthetic fibers also has and well puts out effect.
