As shown in figure 1, in order to solve the danger brought by using explosives, the electromagnetic control automatic fire extinguishing device comprises a body 1, wherein the body 1 is provided with a containing cavity 2, and the containing cavity 2 is filled with liquid carbon dioxide.
Carbon dioxide is a fire extinguishing agent with a history of more than a hundred years, has low price and easy acquisition and preparation, and extinguishes fire mainly by means of a suffocation effect and a partial cooling effect.
Carbon dioxide has a relatively high density, about 1.5 times that of air. At atmospheric pressure, the liquid carbon dioxide is immediately vaporized, and typically 1kg of liquid carbon dioxide can produce about 0.5 cubic meter of gas.
Therefore, when fire is extinguished, the carbon dioxide gas can be exhausted to surround the surface of a burning object or be distributed in a relatively closed space, the oxygen concentration around the combustible or in a protective space is reduced, and the fire is extinguished by a suffocation effect.
In addition, when the carbon dioxide is sprayed out of the storage container, the liquid is quickly vaporized into gas, and partial heat is absorbed from the periphery to play a cooling role.
That is, liquid carbon dioxide is a fire extinguishing medium, is easy to transport, convenient to manufacture, and very low in cost, and has great advantages compared with explosives.
The liquid has low temperature and high pressure, and when the liquid carbon dioxide flows out from the accommodating cavity 2, the liquid carbon dioxide is usually in a spraying state, and meanwhile, the liquid carbon dioxide is changed into gas from liquid.
Carbon dioxide becomes gaseous by liquid, and on the one hand, the absorption heat that carbon dioxide can be rapid reduces ambient temperature, does benefit to put out a fire, and on the other hand, the volume of carbon dioxide expands fast, forms the jet stream, and the jet stream can drive the powder of putting out a fire and spray to, make fire extinguishing medium such as carbon dioxide and the powder of putting out a fire cover the fire source, put out a fire fast.
The accommodating cavity 2 is provided with an inlet 5, the inlet 5 is used for injecting carbon dioxide into the accommodating cavity 2, and the inlet 5 can be provided with a valve core 6, so that the carbon dioxide can be prevented from overflowing from the inlet 5, and the carbon dioxide can be injected into the accommodating cavity 2 very conveniently.
This embodiment is through setting up the chamber 2 that holds that packs with liquid carbon dioxide, thereby, when liquid carbon dioxide flows out from holding chamber 2, on the one hand, carbon dioxide becomes gas by liquid, carbon dioxide can be rapid absorption heat, reduce ambient temperature, do benefit to the fire extinguishing, on the other hand, carbon dioxide becomes gas by liquid, the volume of carbon dioxide expands fast, form the jet stream, the jet stream can drive the powder of putting out a fire and spray, thereby, make fire extinguishing medium such as carbon dioxide and the powder of putting out a fire cover the burning things which may cause a fire disaster, put out a fire fast, therefore, avoid using the explosive, the security that extinguishing device used has been ensured.
In addition, still be used for sealing the solenoid valve 4 who holds the chamber export through the setting, make solenoid valve 4 be connected with control circuit 10 and temperature-sensing ware 11, and then, when the temperature is unusual, temperature-sensing ware 11 senses the temperature difference, then with signal transmission to control circuit 10, control circuit 10 control solenoid valve 4 is timely moved, and solenoid valve 4 relieves the closure to holding the chamber for carbon dioxide is automatic to be spouted and is put out a fire, avoids the flame to stretch into the conflagration, reduces the loss.
Moreover, after putting out a fire, extinguishing device can reuse, reduces use cost.
The application range of the fire extinguishing device is not limited to occasions such as automobiles, houses, warehouses and the like, and can be set and changed according to actual needs.
In order to expand the application range, the body 1 may be provided with an installation portion for connecting a protected area that needs to be protected against combustion, and the fixing manner may be screw connection, snap connection, fastening, or may be welding.
In order to improve the fire extinguishing effect, can make the export 3 direction of export 3 be provided with first cavity 7, first cavity 7 through export 3 intercommunication holds chamber 2, is provided with the powder of putting out a fire in first cavity 7 to, put out a fire with the form that the powder of putting out a fire covers the fire source.
In order to rapidly spray the fire extinguishing powder toward the fire source, the first chamber 7 may be provided with a spray port for discharging the fire extinguishing powder to the outside, and there may be more than one spray port.
In order to increase the spraying range of the fire extinguishing powder, the body 1 can be provided with a shell 8 forming a first chamber 7, the shell 8 is trumpet-shaped, the outlet 3 is arranged at the small end of the spraying opening, and the spraying opening is arranged at the large end of the shell 8.
In order to allow the fire suppressant to remain in the first chamber 7 in a normal state, the ejection opening may be provided with a cover 9, the cover 9 being used to close the ejection opening.
The cap 9 may be a thin-walled frangible plastic film to facilitate release of the closure of the ejection opening.
In order to reduce pollution, the cover 9 may be a metal plate, and the cover 9 is elastically fastened to the body 1, so that the injection opening can be conveniently unsealed, and the cover 9 can be prevented from scattering and breaking.
The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments may be combined with each other into a new embodiment. The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
