Problems solved by technology

[0004] Although continuous water mist has a good fire extinguishing effect on high-power fire sources, it is often not effective in extinguishing "little sparks" that are covered, and often takes longer, and these "little sparks" can easily cause "resurrection". Phenomena, and the pulse fire extinguishing method can produce a large air disturbance to the combustion airflow, and has a better extinguishing effect on "little sparks".

Abstract

The pulse double-fluid water fog extinguishing gun is one fast and efficient fire extinguishing set belonging to the field of public safety emergency aid equipment. It includes a sprayer, a sprayer casing, a spraying pipe, an inner core, a gun body, a middle shaft, a sealing ring, a bearing, an air inlet pipe, an airflow switch, a rotary valve, a retaining block, a water inlet pipe, a water flow switch, a back seat, a connecting block, a fixing nut, a spring, a button switch, a retainer ring, an air inlet hole, a water inlet hole and a notch. The pulse double-fluid water fog extinguishing gun has great extinguishing impact force, high pulse effect, small water fog particle, low water flow loss, high fire controlling power and high extinguishing effect. It is suitable for extinguishing fire of solid, oil and electric equipment.

Description

technical field [0001] The invention relates to a pulse dual-fluid water mist fire extinguishing gun, which belongs to a kind of fast and efficient fire extinguishing equipment and belongs to the technical field of public safety emergency rescue equipment. Background technique [0002] Water is a clean and efficient fire extinguishing agent with convenient sources and no pollution. However, in common water sprinkler systems, the water particles are large in size, small in surface area, and slow in vaporization speed. They can easily fall to the ground under the action of gravity and become ineffective. The running water has a low water utilization rate, and a large amount of water loss may also cause secondary water pollution. According to statistics, about 90% of the direct current water used for fire extinguishing flows during fire extinguishing, and only a small part of it really works on fire extinguishing; Difficulty; in addition, DC water is not suitable for extinguis...
