Abstract

The invention relates to a pulse air pressure type fire water gun, comprising an air storage tank, a liquid storage tank, and a multi-way combination valve arranged at the air inlet of the liquid storage tank for controlling the communication between the air storage tank and the liquid storage tank (3); wherein the air storage tank is an annular cylindrical structure arranged around the liquid storage tank and the multi-way combination valve (3). The injector has a smooth high-pressure gas injection channel, thereby improving the injection kinetic energy and impact force of the sprayed water mist, and can adjust the air pressure of the injected gas according to the needs of the operation.

Description

technical field

[0001] The invention relates to a pulse air pressure type fire-fighting water gun. Specifically, the invention proposes an improved structure for improving the efficiency of the fire-fighting water gun. Background technique

[0002] In the past fire-fighting tools, in order to avoid a large amount of discharge of fire-extinguishing agent and can not be effectively utilized, and to improve the efficiency of fire-extinguishing, the fire-extinguishing gun that adopts air pressure pulse spray mode has been invented. This fire extinguishing gun, as described in the Chinese patent document CN1260219A, includes a water storage tank, an air storage tank and a multi-way valve connected with the air storage tank and the water storage tank. The multi-way valve has a main valve and a pilot valve, and the The main valve is set between the air storage tank and the water storage tank. The pilot valve is provided with two positions respectively connected to the pressurized g...
