What fire extinguishers should be equipped with a computer room?
The electric fire extinguisher can be equipped with electric appliances in the building. The fire extinguisher works best.
Carbon dioxide fire extinguisher principle: carbon dioxide has a higher density, about 1.5 times the air. At normal pressure, liquid carbon dioxide vaporizes immediately, and liquid carbon dioxide, typically 1kg, produces about 0.5 cubic meters of gas. Therefore, when the fire, carbon dioxide gas can eliminate the air and surround the surface of the object or the distribution of combustion in a relatively closed space, reducing the fuel around or in the protection room oxygen concentration, produce suffocation and fire. In addition, when carbon dioxide is ejected from the storage vessel, it is rapidly vaporized into a gas by the liquid, which absorbs some of the heat from the surrounding and acts as a cooling agent.
Structure: carbon dioxide fire extinguisher cylinder is made of high quality alloy steel. It is processed by special process, and the weight is 40% lower than that of carbon steel. The utility model has the advantages of convenient operation, safety, reliability, easy preservation, portability, beauty and the like. Principle of fire extinguishing: storage of liquid carbon dioxide in bottle body of fire extinguisher, when working, press down the handle of bottle valve. The carbon dioxide fire extinguishing agent from the rainbow after Straw bottle valve to spray spray, the concentration of oxygen in the combustion zone decreased rapidly when CO2 concentration will reach enough flame extinguished due to suffocation, liquid carbon dioxide will vaporize rapidly, absorb large amount of heat in a very short period of time, so some cooling effect the combustion products, also contribute to the fire. The utility model relates to a cart type carbon dioxide fire extinguisher, mainly composed of a bottle body, a head assembly, a nozzle assembly, a frame assembly, etc., and the extinguishing agent inside is a liquid carbon dioxide fire extinguishing agent. At the beginning of the fire for inflammable liquid and gas, also can save electric equipment fire; often used in laboratories, computer rooms, substation, and the place of sophisticated electronic equipment, expensive equipment or items requiring high maintenance.
