Description
Technical Field
The utility model relates to a fire-fighting equipment technical field, concretely relates to fire extinguishing agent storage bottle and use extinguishing device of this storage bottle.
Background
The existing non-pressure-storage fire extinguishing device uses dry powder as fire extinguishing agent. The working mode is as follows: the dry powder and the gas generating grain are simultaneously installed in the fire extinguishing device and are communicated with each other, when the fire extinguishing device works, the gas generating grain generates chemical reaction to generate a certain amount of gas with pressure, and the gas with pressure sprays the dry powder out of a preset fire extinguishing area outside the storage device to extinguish fire. The dry powder is used as the fire extinguishing agent in the non-pressure-storage fire extinguishing device because the dry powder is powdery solid and does not produce chemical reaction with the gas producing explosive column or reduce the working performance of the explosive column. Although the problem of no pressure in the non-working state of the fire extinguishing device is realized; but the application range of the dry powder extinguishing agent is limited. If the fire extinguishing agent in the non-pressure-storage fire extinguishing device is a liquid fire extinguishing agent, the fire extinguishing agent and the gas generating explosive column are arranged in a communicated storage device, the liquid fire extinguishing agent tends to soak the gas generating explosive column, then the gas generating explosive column cannot work normally, no gas with pressure for driving the fire extinguishing agent is generated, and the whole non-pressure-storage fire extinguishing device adopting the liquid fire extinguishing agent cannot perform the fire extinguishing function.
The non-pressure storage device of a liquid fire extinguishing agent is a piston type non-pressure storage fire extinguishing device, and the structure and the working mode of the non-pressure storage fire extinguishing device are as follows: a piston (double sealing ring structure) is arranged in a circular cylinder, a front sealing cover is arranged at the front end of the circular cylinder, and an opening (used for spraying fire extinguishing agent) is formed in the front end of the circular cylinder. The cavity formed between the front sealing cover and the piston is used for storing the liquid fire extinguishing agent, and the liquid fire extinguishing agent is prevented from entering the rear end of the support by the sealing performance of the double-sealing ring structure of the piston. The round cylinder body at the rear end of the piston is internally provided with the gas generating explosive column and the rear sealing cover, and a sealing device is formed through the structure. Although the structure solves the problem that the liquid fire extinguishing agent affects the gas generating grain, the piston with the double-sealing ring structure is used as a sealing and pushing element, so that the requirements of the cylinder body processing of the fire extinguishing device on the roundness and the smoothness of an inner hole are high, the requirements on the corrosion resistance of the inner wall of the cylinder body are high, the requirements on the processing precision and the dimensional tolerance of the piston are also high, and the cost of the manufactured device is inevitably high.
