A rotatable high-pressure closed-type fine water mist spray gun

Abstract

A rotary and high-pressure closed type water mist spraying gun comprises a gun body. The gun body comprises a gas-liquid mixing chamber, a high pressure gas pipe connected with the gas-liquid mixing chamber, a liquid conveying pipe and nozzles arranged at the tail end of the gas-liquid mixing chamber; a rotary connection device is arranged in the connection position of the nozzles and the tail end of the gas-liquid mixing chamber and comprises a barrel, a rotary ring rotationally connected to one end of the barrel and a rotary impeller arranged inside the barrel; the outer wall of the impeller and the inner wall of the barrel are fixedly connected; the other end of the barrel is sealed; at least one inclined connection hole is formed in the lateral wall, near the sealed end, of the barrel and connected with the nozzles in a sealed mode; at least one circle of arc groove is formed in the outer surface of the rotary ring; a groove matched with the outer diameter and the length of the rotary ring is formed in the inner wall of the gas-liquid mixing chamber; an arc groove corresponding to the arc groove in the outer surface of the rotary ring is formed in the inner wall of the groove; multiple balls are arranged inside the arc groove. The spraying efficiency is greatly improved, and the fire extinguishing effect is improved.

Description

technical field [0001] The invention relates to the field of production of fine water mist extinguishing equipment, in particular to a fine water mist fire extinguishing gun. Background technique [0002] Water mist fire extinguishing has been widely used due to its good fire extinguishing effect, but the fire extinguishing guns in the prior art cannot automatically rotate at multiple angles, resulting in a small spray area, and the effect needs to be further improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a rotary fine water mist fire extinguishing gun with a wide spraying area and effective all-round spraying by a plurality of nozzles. [0004] In order to achieve the purpose of the present invention, the following technical solutions are provided: a rotatable high-pressure closed-type fine water mist spray gun, including a gun body, the gun body includes a gas-liquid mixing chamber, a high-pressure gas pip...
