High-pressure nozzle structure capable of increasing foaming times

Abstract

The invention provides a high-pressure spray head structure capable of increasing foaming times, a mixing chamber (3) is axially arranged in a spray head body (1), a foam suction pipe (4) of the spray head body (1) is communicated with a foam bottle assembly, the foam suction pipe (4) extends into the spray head body (1) to be communicated with the mixing chamber (3), and the spray head body (1) is connected with a water flow spraying holding pipe (7) through a quick connector (6). The spray nozzle body (1) is provided with a spray holding pipe (7), the spray holding pipe (7) is communicated with the mixing chamber (3), the spray nozzle body (1) is detachably connected with the extended foaming pipe (2), the other end of the extended foaming pipe (2) is a foam outlet (8), the mixing chamber (3) is communicated with a foam generating chamber (10) in the extended foaming pipe (2) through a nozzle (11) and a conveying channel I (12), and a foaming net (13) is arranged between the nozzle (11) and the conveying channel (12). The foam covering effect is good, the range is long, and therefore the fire extinguishing effect is improved.

Description

technical field [0001] The invention relates to a structure of a high-pressure spray head which increases the expansion ratio. Background technique [0002] The current nozzle only has a mixing chamber, and the foam and water are only mixed in the mixing chamber. The foam quality of the foam produced in this way is relatively poor, and the fire extinguishing effect when applied to the fire extinguishing equipment is not good, and the range is relatively short, so it cannot be used. For long-distance jet fire extinguishing, the scope of application is relatively narrow. Contents of the invention [0003] The invention provides a high-pressure nozzle structure with increased foaming ratio, which not only can produce foam with good foaming quality and uniform foaming, but also has a good covering effect of the foam and has a long shooting range, thereby improving the fire extinguishing effect. [0004] The present invention adopts the following technical solutions: a structu...
