High-pressure sprayer

Abstract

The invention discloses a high-pressure sprayer. The high-pressure sprayer comprises a shell, an empty cavity, a spray nozzle, a fire-extinguishing gas spray pipe, a filtering chamber, a liquid pressurizing chamber and a regulating support, wherein the empty cavity is internally provided with a metal coil pipe which is of a hollow structure; one end of the metal coil pipe is connected with the fire-extinguishing gas spray pipe, and the other end of the metal coil pipe is connected with the gas pressurizing chamber; the filtering chamber is connected to one side, which is opposite to the connection of the empty cavity and the spray nozzle, of the empty cavity; the other end of the filtering chamber is connected with a water pipe; a seal ring is arranged at the connection part of the filtering chamber and the water pipe so as to prevent water leakage between the filtering chamber and the water pipe. The high-pressure sprayer is high in fire extinguishing efficiency, meanwhile can be used for saving water resources and is adjustable in shooting range and simple in structure.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a high-pressure nozzle for fire protection. Background technique [0002] When a fire breaks out, the fire-fighting water is sprayed through the nozzle to control the fire in a certain area. The existing nozzles are generally drooping nozzles, one end of which is installed on the water supply pipe. The sprayed water is in the form of a parabola, with a total water volume of 80% to 100% is sprayed to the ground, a large amount of water resources are wasted in fire control, the cost of firefighting is improved, and it is inconvenient to use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-pressure nozzle with high fire extinguishing efficiency, which can spray high-pressure liquid and high-pressure gas at the same time, and adopts a double-hole form. [0004] A high-pressure sprinkler head includes a sh...
