Hand-held high-pressure water mist spray nozzle and operating method thereof

Abstract

The invention discloses a hand-held high-pressure water mist spray nozzle and an operating method thereof. The spray nozzle comprises a spray gun joint, a rotary gear shift, a gear shift seat, a jet pipe seat, a remote jet steel tube, a remote water mist spray nozzle, a foam jet spray nozzle, a short-range water mist spray nozzle, a short-range water mist scattering spray nozzle and a short-range jet steel tube, wherein the rotary gear shift is arranged between the gear shift seat and the spray gun joint; and the right end of the jet pipe seat is respectively connected with the remote jet steel tube, the foam jet spray nozzle and the short-range jet steel tube by threads. In the operating method, according to demands of a fire-fighting object, the rotary gear shift is rotated to set the fire-fighting ways to be a foam fire-fighting way, a short-range water mist scattering extinguishment way or a remote jet water mist extinguishment. The invention has the advantages of having a water fire extinguisher and a foam fire extinguisher; two fire-fighting ways of a combined multi-nozzle short-range scattering and a remote single nozzle jet are used in the water mist fire-fighting way, thus greatly improving the fire-fighting effect and broadening the fire-fighting scope.

Description

Technical field [0001] The invention relates to a high-pressure water mist fire extinguishing device, in particular to a high-pressure water mist nozzle and a working method thereof. Background technique [0002] The hand-held fire sprinkler is the front spray device of the hand-held fire gun. The traditional hand-held fire sprinkler has a single function, and only has a single water mist spray function or a foam spray function. Foam fire extinguishing has the advantages of high foaming ratio and can quickly fill the fire space in a short time. It is mainly suitable for fighting various solid combustible fires such as oil, wood, fiber, rubber, etc., but it is suitable for underground engineering, ships, and valuable equipment. The fire extinguishing effect of the objects and the objects is poor. High-pressure water mist can extinguish fires quickly. It has the characteristics of no pollution, small on-site damage, good extinguishing effect, low water consumption, good electrica...

AI Technical Summary

Problems solved by technology

The traditional hand-held fire sprinkler has a single function, only a single fine water mist spray function or foam spray function

Foam fire extinguishing has the advantages of high foaming ratio and can quickly fill the fire space in a short time. It is mainly suitable for extinguishing various oil, wood, fiber, rubber and other solid combustible fires. and items are less effective in extinguishing fire

High-pressure water mist can extinguish the fire quickly, has the characteristics of no pollution, small damage on site, good fire extinguishing effect, small water consumption, good electrical insulation, suitable for extinguishing three types of fires A, B, and C, and easy to use. However, because the high-pressure water fine mist system has strict requirements on the particle size of water particles, the spray distance is small, and the hand-held operation space is small.
