Abstract
The utility model provides an automatic extinguisher for fire extinguishing, which comprises a storage steel bottle of fire extinguishing agents, a fire detector, a bottle head valve, a signal feedback device and a nozzle, wherein, the top part of the steel bottle is provided with the bottle head valve; a straight through lancet is arranged in the upper valve of the bottle head valve; the lancet is provided with an upper piston and a lower piston; the piston can drive the lancet to move in the upper valve body. The nozzle is connected with the outlet end of the bottle head valve through a pipeline. The pipeline is provided with the signal feedback device. The signal feedback device is provided with an end cover, a spring sheet and a spring seat. A water spraying nozzle is selected as the nozzle. The fire detector transports control signal to the bottle head valve when fire happens. Then the automatic fire extinguisher can automatically spray fire extinguishing agents for extinguishing fire.
Description
The utility model relates to a kind of fire-fighting equipment, the Automatic Fire Extinguisher that particularly a kind of fire-fighting is used.
At present, the Automatic Fire Extinguisher and the fixed automatic fire extinguisher device of widespread usage are storage of higher pressures both at home and abroad.Be characterized in: the bottle valve fluid resistance loss is big, and the signal feedback device volume is big, and is fragile.Shower nozzle sprays inhomogeneous, reliability is low, just there are these shortcomings in automatic fire extinguisher as productions such as Japanese Nohmi Bosai Ltd. and Xi'an 524 factories of nuclear industry parent company, its fault of construction is: when extinguishing chemical sprays by bottle valve, all need in valve, to change 1-2 the curved valve drag losses that so just increased, make the extinguishing chemical pressure store increase, signal feedback device is piston and touches the micro limit switch structure, be characterized in that volume is big, fragile, shower nozzle is the direct spray-type of several apertures, and this structure extinguishing chemical sprays inhomogeneous, and atomization speed is slow.
The utility model is exactly the above-mentioned shortcoming that exists at prior art, mainly to bottle valve, feedback device, nozzle are improved and a kind of fire extinguisher of designing, and it is low that this Automatic Fire Extinguisher has an extinguishing chemical pressure store, the bottle valve fluid resistance loss is little, starting current is little, and the signal feedback device volume is little, and cost is low, extinguishing chemical sprays evenly, high reliability features.
The utility model is by the extinguishing chemical storage cylinder fitted, fire detecting arrangement, and bottle valve, signal feedback device, nozzle, lead and pipeline are formed.Bottle valve is made up of upper and lower valve, dispose in the valve body of last valve and stab out pin, stab out and dispose upper and lower two pistons on the pin, in the cavity of two piston centres electric starter is housed, the valve body upper end disposes an adapter, is provided with slip pipe moving up and down in the adapter, handle is installed on the slip pipe, adapter is fixed on the valve body by pressure cap, in the following valve body metallic film is housed, and supporting pad is housed between the valve up and down.Signal feedback device is made up of joint, piston, spring, spring base, housing, spring leaf and end cap, and a piston is arranged in the joint, and the other end of piston is equipped with spring base, and a back-moving spring is set on the spring base, and spring base is made by conductive material.Housing is housed on the joint, and the other end of housing is installed an end cap, and two spring leafs have been adorned in the end cap inboard, and end cap is made by non-conducting material, and nozzle is selected the water spray shower nozzle for use, is made up of nozzle body and orifice plate.
The basic principle of Automatic Fire Extinguisher is: when the condition of a fire, fire detecting arrangement carries the signal of telecommunication to give a bottle mouth, and bottle valve is opened, and to nozzle, put out a fire by ejection by bottle valve for the extinguishing chemical in the extinguishing chemical storage cylinder fitted.When extinguishing chemical flow to the feedback device place, extinguishing chemical self pressure made the feedback device action, and gave fire detecting arrangement with the signal feedback that Automatic Fire Extinguisher has been started working.
Fig. 1 is an Automatic Fire Extinguisher operation principle schematic diagram.
Fig. 2 is the signal feedback device structural representation.
Fig. 3 is the nozzle arrangements schematic diagram.
Fig. 4 is the bottle valve structural representation.
Wherein: (1) among Fig. 1 is signal feedback device, (2) be nozzle, (3) be fire detecting arrangement, (4) be pipeline, (5) be bottle valve, (6) be lead, (7) be the extinguishing chemical storage cylinder fitted, (8) among Fig. 2 are leads, (9) be end cap, (10) be spring leaf, (11) be spring, (12) be housing, (13) be spring base, (14) be joint, (15) be piston, (16) among Fig. 3 are nozzles, (17) be orifice plate, (18) among Fig. 4 are slip pipes, (19) be handle, (20) be to take over, (21) be pressure cap, (22) be upper piston, (23) be electric starter, (24) be lead, (25) be lower piston, (26) be to stab out pin, (27) be upper valve body, (28) be following valve body, (29) be supporting pad, (30) be metallic film.
The utility model is described in further detail below in conjunction with accompanying drawing:
When the condition of a fire, fire detecting arrangement (3) carries the signal of telecommunication to give the action of the electric starter (23) in bottle valve (5), the bottle valve (5) by lead (6) and (24), promotion lower piston (25), lower piston (25) drive stab out pin (26) and move down, stab out metallic film (30), extinguishing chemical in the extinguishing chemical storage cylinder fitted (7) promptly flow to nozzle (2), extinguishing chemical and flow through orifice plate (17) formation bumpy flow in nozzle (2), and bumpy flow is put out a fire with vaporific ejection under centrifugal action through nozzle body (16).When extinguishing chemical flows through feedback device (1) when locating, extinguishing chemical self pressure promotes piston (15) and moves, even two bullets are built sheet (10) and are all built seat (13) with bullet and contact, so just form electric loop, given fire detecting arrangement (3) with the signal feedback that Automatic Fire Extinguisher is started working, after automatic startup is malfunctioning, staff can press down handle (19), drive slip pipe (18) promotes to stab out pin (26) and moves down, can start Automatic Fire Extinguisher, use several Automatic Fire Extinguishers at the same time, as long as a startup is arranged, extinguishing chemical in the fire extinguisher that has started can flow to upper piston (22) epicoele by the perforate that stabs out pin (26) upper end, along the adapter on the pressure cap (21) by the road (4) flow in upper piston (22) epicoele of several Automatic Fire Extinguishers in addition, promotion upper piston (22) drive stabs out pin (26) and moves down, and other is started by an Automatic Fire Extinguisher.In the time of in extinguishing chemical flow to upper piston (22) epicoele, upper piston (22) drive that also can promote this valve stabs out pin (26) and moves down, accelerate self starting of this Automatic Fire Extinguisher, this effect just can make starting current diminish, because the straight-through of bottle valve (5) just makes fluid resistance loss reduce, and then can reduce the pressure store of fire extinguisher.
