Background technique
Fire-fighting fire extinguishing is the very important sign of a progress of modern society, the progress of fire prevention and equipment is the progressive degree of a society of reflection, China's fire prevention and production development are rapid in recent years, but fire takes place really to increase severely with day, this is because social progress, the application of at present a large amount of plastic materialss, the continuous increase in the market of various simple and easy installations and furniture store and free market etc., there is the fire gear technology to relatively lag behind again, nearly all modern fire prevention all is external invention, lacks the original technology that tallies with the national condition in China and causes.
China is extensive use of automatic sprinkling system and adopts two kinds of methods substantially at present, a kind of is wet pipe system, a kind of is dry system, shower nozzle adopts glass bulb or easy molten metal substantially in wet pipe system, during work since glass bulb in medium be subjected to Temperature Influence, expansion causes the broken water ejection of glass bulb fire extinguishing, and combustible metal is because high temperature makes combustible metal dissolve, open shower nozzle and make water ejection fire extinguishing, this kind method is damage type, in case stopping the back system, system works water ejection fire can not stop automatically, cause the loss of water enchroachment (invasion) very big, need shutdown system manually, the current anhydrous fire extinguishing of back secondary resume combustion to the greatest extent sometimes, no matter glass bulb formula or combustible metal formula are damage type, in case the nozzle system that need more renew after the system works just can continue to use.Dry system is because shower nozzle adopts deluge system, therefore there is not firing-fighting medium in the system, need adopt methods such as temperature detecting temperature sensing when temperature variation, open drench valve water is passed to shower nozzle, dry system can't be worked under the support that does not have power supply as can be seen at this point.
Above dual mode is the best fire-fighting mode of generally acknowledging at present, but all huger because of system, price is also high, therefore, only be applicable to the hotel, restaurant and some large enterprises, be difficult to use for smaller fire prevention area and scope, and it is just more impracticable to need the frpf area to use to some, for example school, the kindergarten, geracomium, hospital, area, warehouse or the like does not all have the measure of automatic fire control, these become the dead angle of causing fire to bring out, and modern fire gear can't be implemented.
Summary of the invention
The purpose of this utility model provides a kind of installing and using simply, and can open valve voluntarily and make the shower nozzle sprinkling fire not by external force when abnormal high temperature takes place.And temperature descends after fire stops, and valve stops to supply water automatically, the anhydrous ejection of shower nozzle, and no matter opening or closing valve can work repeatedly.
For reaching the purpose of this utility model, the design has utilized marmem as temp-sensing element, utilize its thrust that when different temperatures, produces that magnet ring is moved up, the magnetic core that influences in the valve together moves up, pressure reduction changes about causing the piston in the valve, piston is moved up, and hydraulic pressure outwards sprays by valve body.During same normal temperature, marmem is contraction-like, bias spring is to lower compression magnet ring cover in the outer cover, magnet ring in the magnet ring cover moves down, under the effect of the magnetic line of force, the core assembly in the piston sleeve together moves down, and the interior hydraulic pressure of middle relief hole piston sleeve that stops up piston assembly rises piston assembly is promoted downwards, piston assembly stops up the anhydrous discharge of valve with the osculum of valve body.
Owing to adopted marmem, the variation of different deformation drive magnet ring moves up and down under different temperatures, influence by the magnetic line of force makes the core assembly in the piston sleeve together move up and down, valve is in the opening type closing state, thereby accomplished need not the external force power supply, valve just can be in water spray exactly or stop water spray ground state by variation of temperature, thereby reaches the purpose of this utility model.
