Embodiment Construction

[0031] The portable water mist fire extinguisher includes a nozzle 1 , an on-off valve 2 , a pressure reducing valve 3 , a casing 4 and a suction pipe 5 . Such asfigure 1 shown. The nozzle 1 is installed on the pressure reducing valve 3 and connected by thread; the switch valve 2 is installed on the shell 4 and connected by thread; the pressure reducing valve 3 is installed on the outlet of the switch valve and connected by thread; the suction pipe 5 is installed on the lower end of the switch valve 2 , connected by threads.

[0032] Such as figure 2 As shown, the switching valve includes a valve core 201, a valve body 202, a spring 204, a pressure gauge 206, a lower handle 208, and an upper handle 2.9. Such as figure 2 shown.

[0033] The on-off valve 3 is connected to the housing 4 through threads, and an O-ring 203 is used to ensure a reliable seal. The spool 201 and the valve body 202 are cone-sealed. In order to ensure the sealing of the system and not leak outward...

Abstract

The invention discloses a portable water mist fire extinguisher, which comprises a nozzle (1), a switching valve (2), a pressure reducing valve (3), a shell (4) and a straw (5). The switching valve (2) is arranged at an opening on the upper part of the shell (4); the pressure reducing valve (3) is arranged on the switching valve (2); the nozzle (1) is connected with the pressure reducing valve (3); one end of the straw (5) is connected with the switching valve (2), and the other end of the straw (5) penetrates into the shell (4); and water in the shell (4) passes through the straw (5) and the switching valve (2) and enters the pressure reducing valve (3), and pressure water subjected to pressure reduction by the pressure reducing valve (3) flows out of the nozzle (1) to form water mist. The portable water mist fire extinguisher can effectively extinguish various types of fire, and has high environment compatibility, constant working pressure, high fire extinguishing efficiency, light weight and small volume.

Description

technical field [0001] The invention relates to a portable fire extinguisher, which uses tap water and inert gas as working media. The present invention can be used in fire-fighting systems to extinguish various types of fires, and is especially suitable for various places with high protection requirements, such as libraries, archives, computer rooms, museums, and airplanes. Background technique [0002] There are many types of portable fire extinguishers, mainly divided into the following categories: [0003] (1) Dry powder fire extinguisher: The dry powder fire extinguisher is filled with dry powder fire extinguishing agent. Dry powder fire extinguishing agent is a dry and easy-flowing fine powder used for fire extinguishing. It is composed of inorganic salt with fire extinguishing effect and a small amount of additives after drying, crushing and mixing to form a fine solid powder. The dry powder fire extinguishing agent mainly extinguishes the fire through the physical ...
