Energy storage type high-pressure spray extinguisher

Abstract

An energy storage type high-pressure spray extinguisher comprises a steel cylinder. A control valve assembly is mounted at one end of the steel cylinder. A safety valve 1, a pressure regulating valve, an output connector, a water injection connector and a pressure detecting connector are mounted on the control valve assembly; an inflation connector is mounted at the other end of the steel cylinder, coercible gas is injected into an inner cavity of the steel cylinder through the inflation connector to realize first-time storage of compression energy, high pressure water is injected through the water injection connector, and the injected coercible gas is compressed to reduce the volume thereof so as to realize second-time storage of the compression energy; the compression energy stored in the steel cylinder is released through the injected coercible gas, the coercible gas is quickly expanded in volume to extrude the high pressure water stored in the inner cavity of the steel cylinder, and the high pressure water is conveyed to an atomizer through the pressure regulating valve, the output connector and a pipeline to be sprayed out. According to the energy storage type high-pressure spray extinguisher, the compression energy stored in the extinguisher is released to compress the high pressure water stored in the closed cavity to be sprayed out continuously from the output connector, the working pressure required by the high-pressure spray extinguisher is reached, and high-pressure spray extinguishment is realized by means of connection to the atomizer.

Description

technical field [0001] The invention relates to the technical field of high-pressure water mist fire extinguishing, in particular to an energy storage type high-pressure water mist fire extinguisher. technical background [0002] Chinese patent CN101574564A discloses a portable water mist fire extinguisher, which uses high pressure to dissolve carbon dioxide in water and reach a supersaturated state; at the same time, uses undissolved carbon dioxide high-pressure gas as the driving pressure for spraying fine water mist to achieve a single bottle of fine water mist Extinguishing. Although the fire extinguisher is designed with a single-bottle structure, it is portable, medium-pressure, and single-tube delivery method to realize bubble atomization and fine water mist. It has the characteristics of simple structure and convenient use. The atomization effect of water saturated with carbon dioxide is greatly limited, so that the fire extinguishing effect is greatly reduced. Con...

Problems solved by technology

Although the fire extinguisher is designed with a single-bottle structure, it is portable, medium-pressure, and single-tube delivery method to realize bubble atomization and fine water mist. It has the characteristics of simple structure and convenient use. The atomization effect of water saturated with carbon dioxide is greatly limited, so that the fire extinguishing effect is greatly reduced

Conventional two-fluid atomization technology generally requires two pressure storage cylinders to store water and high-pressure gas respectively; two delivery pipelines to deliver water and auxiliary atomized gas respectively; Good, but the system is complex, difficult to carry, and inconvenient to use
