Detailed Description
Examples
China frequently generates casualty events caused by fire every year, and huge economic loss is also brought. In the festival, the fire caused by setting off fireworks is increased, the fire in small places such as construction sites, agricultural and sideline production and rental houses, three-in-one workshops and small shops is more, and the fire caused by using electric fire still accounts for a larger proportion. For this reason, fire extinguishers are widely used. The fire extinguisher is used as a portable fire extinguishing tool, chemical substances are placed in the fire extinguisher, the components filled in different kinds of fire extinguishers are different, and the fire extinguisher is usually stored in public places or places where fire disasters can happen and is specially designed for different fire disasters to extinguish the fire. The fire extinguishers are of various types and can be divided into the following modes according to the moving mode: hand-held and cart-based; the power sources for driving the fire extinguishing agent can be divided into: gas storage bottle type, pressure storage type and chemical reaction type; the fire extinguishing agent filled in the fire extinguishing agent can be divided into: foam extinguishers, dry powder extinguishers, carbon dioxide extinguishers, water-based extinguishers, and the like.
The foam fire extinguisher is internally provided with two containers which are respectively used for containing two liquids, namely aluminum sulfate solution and sodium bicarbonate solution, the two solutions are not contacted with each other and do not have any chemical reaction. When the foam fire extinguisher is needed, the fire extinguisher is inverted, and the two solutions are mixed together, so that a large amount of carbon dioxide gas can be generated. In addition to the two reactants, some blowing agent is added to the extinguisher. When the switch is turned on, the foam is sprayed out of the fire extinguisher to cover the burning objects, so that the burning objects are isolated from the air, the temperature is reduced, and the fire extinguishing purpose is achieved.
The dry powder fire extinguisher is filled with a dry powder fire extinguishing agent. The dry powder extinguishing agent is dry and easy-to-flow fine powder for extinguishing fire, is composed of inorganic salt with fire extinguishing effect and a small amount of additive, and is formed into fine solid powder by drying, crushing and mixing, wherein the dry powder (mainly containing sodium bicarbonate) is blown out by mainly utilizing compressed carbon dioxide to extinguish the fire.
Liquid carbon dioxide is stored in the bottle body of the carbon dioxide fire extinguisher, during operation, when the pressure handle of the bottle valve is pressed down, the carbon dioxide fire extinguishing agent inside is sprayed out from the siphon pipe to the spray tube through the bottle valve, so that the oxygen concentration in a combustion area is rapidly reduced, when the carbon dioxide reaches enough concentration, flame can be choked and extinguished, meanwhile, because the liquid carbon dioxide can be rapidly gasified, a large amount of heat can be absorbed in a short time, therefore, the carbon dioxide fire extinguisher plays a certain cooling role for the combustion objects, and is also helpful for fire extinguishment.
The fire extinguishing agent in the water-based fire extinguisher is mainly clear water, the water has lower viscosity, higher thermal stability, higher density and higher surface tension at normal temperature, and the fire extinguishing agent mainly extinguishes fire by cooling and suffocation. Since each kilogram of water is heated from normal temperature to boiling point and completely vaporized, 2593.4KJ of heat can be absorbed. Therefore, the capacity of self-absorbing sensible heat and latent heat is utilized to play a role in cooling and extinguishing fire, which is incomparable with other fire extinguishing agents. In addition, the water vapor formed by the vaporization of water is an inert gas and will expand by about 1700 times in volume. When fire is extinguished, the water vapor generated by water vaporization occupies the space of a combustion area, dilutes the oxygen content around a combustion object, prevents fresh air from entering the combustion area, greatly reduces the oxygen concentration in the combustion area, and achieves the aim of suffocation fire extinguishment. When the water is in the form of spray mist, the specific surface area of formed water drops and mist drops is greatly increased, and the heat exchange effect between the water and fire is enhanced, so that the cooling and suffocation effects of the water and fire are enhanced. In addition, the liquid can also dilute some flammable and combustible liquids which are easily dissolved in water; the water mist generated by the strong jet flow can enable combustible and flammable liquid to generate emulsification, so that the liquid surface is rapidly cooled, and the generation speed of combustible steam is reduced, thereby achieving the purpose of fire extinguishing.
The water-based fire extinguisher widely used in the market has the following defects: when the fire extinguisher inclines or inverts, the fire extinguishing agent flows backwards easily and corrodes the rust phenomenon with the internal thread contact of fire extinguisher barrel, leads to fire extinguisher barrel and valve body to be difficult to dismantle, and the fire extinguisher can't load the fire extinguishing agent again and carry out reuse.
Based on the problems, as shown in fig. 1 and fig. 2, the embodiment provides a cylinder body structure of a fire extinguisher, which comprises a main body, wherein the valve interface position of the main body is provided with external threads, the external threads are provided with a screw gland, and a valve body of the water-based fire extinguisher can extend into the valve interface of the main body and is fixed on the main body through the screw gland. The valve extends into the valve port and is connected with the valve port in a sealing mode, the threaded gland is provided with internal threads matched with the external threads, and the valve body is tightly pressed and fixed on the main body through the threaded gland. The utility model discloses set up the external screw thread in the valve interface position of main part, the fire extinguisher fire extinguishing agent can not contact with the external screw thread when slope or inversion, and the effectual external screw thread of having avoided the main part is corroded rust phenomenon by the fire extinguishing agent, has solved the problem that fire extinguisher tube structure and valve body are difficult to dismantle and the fire extinguisher can't load fire extinguishing agent reuse again.
It should be noted that the fire extinguisher cylinder structure is not only suitable for water-based fire extinguishers, but also can be used in other fire extinguishers, and can avoid the problem that the fire extinguisher cylinder and the valve body are difficult to disassemble due to corrosion of the fire extinguisher cylinder.
Specifically, the main body comprises a middle connecting cylinder 1, an upper end enclosure 2 and a lower end enclosure 3 are respectively arranged at two ends of the middle connecting cylinder 1, the upper end enclosure 2 is connected with a cylinder joint 4, the cylinder joint 4 is provided with a valve port, and the surface of the cylinder joint 4 is provided with the external threads; the lower end enclosure 3 is connected with a cylinder seat 5.

Wherein, the both ends of intermediate junction section of thick bamboo 1 pass through welded fastening with upper cover 2 and low head 3 respectively. The bottom of the lower end enclosure 3 is arc-shaped, the inner wall of the cylinder seat 5 is provided with a circle of protruding parts 6, and the protruding parts 6 are in contact with the outer wall of the lower end enclosure 3 so as to support the lower end enclosure 3 and improve the stability of the cylinder structure.
