Cyclone fine mist spray head

Abstract

A cyclone nozzle able to highly atomize water for extinguishing fire is composed of main body with front blind hole, boosting airflow holes on its periphery, internal mixing cavity consisting of slender holes, internal flow guiding post, and holder of cyclone nozzle. Its advantages are long spray distance, high atomizing effect and long service life.

Description

1. Technical field [0001] The invention relates to a special-purpose high-pressure fine water mist spray nozzle, in particular to a cyclone type fine water mist spray nozzle for a fine water mist fire extinguishing device capable of extinguishing fires in a large area remotely. 2. Background technology [0002] At present, the structure of the known common high-pressure water mist nozzle is a conical hexahedron shape, and 5-9 nozzles in the form of nozzles are installed on the cone surface. The range of strong fog spraying can achieve the effect of fire extinguishing by spraying fine water mist. However, due to structural problems, the flow rate in use is small, the range is short, and the spray surface is small, which cannot meet the needs of fire extinguishing. Therefore, the innovation of nozzles is imperative. . 3. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned common high-pressure water mist nozzle installed in the mo...

Problems solved by technology

[0003] In order to overcome the disadvantages of the above-mentioned common high-pressure water mist nozzle installed in the mobile high-pressure water mist fire extinguishing device to extinguish high places, remote places and large-area fire sources, the purpose of the present invention is to provide a cyclone type fine water mist nozzle. The nozzle not only has the advantages of ordinary high-pressure water mist nozzles, but also can solve the problem of remote spray fire extinguishing. The technical solution is: drill a large blind hole on the nozzle body, and then drill 2-7 long and thin holes. A three-dimensional curved guide column is installed in the hole. At the place where the high-pressure water mist is sprayed, 1-6 airflow boosting holes are drilled on the outer wall of the nozzle. It enters the nozzle from the gun shaft, and passes through the three-dimensional curved diversion column on the nozzle body to rotate the high-pressure and high-speed water flow to enhance its turbulent flow intensity. After fully mixing in the mixing chamber of the nozzle body, it is sprayed out from the thin-walled hole to form Water mist, when a large amount of water mist is sprayed, the air in the groove of the nozzle is entrained to form a negative pressure area, and the air outside the nozzle enters the groove from the holes around the groove, and the air and water mist are mixed and sprayed forward. , the structure of the present invention is that there is a large blind hole at the end of the nozzle body, and an airflow booster hole communicating with the large blind hole is arranged on the periphery. The body and the cyclone nozzle seat are connected together, the mixing chamber communicates with the big blind hole through the nozzle hole, the inner opening of the airflow booster hole is placed in the groove, and the assembly hole with internal thread is provided at the end of the cyclone nozzle seat. The structure of the present invention is novel and unique. Easy to use, long range, good atomization effect, long service life, wide application, huge economic and social benefits
