Embodiment 1

[0020] Such as figure 1 As shown, the present invention provides a two-fluid jet water mist fire extinguishing gun, which is characterized in that it is composed of a fire extinguishing gun body 1, a gas-liquid supply package 2, a pressure gas input pipe 3 and a liquid input pipe 4 connected. The fire extinguishing gun body 1 of fire extinguishing gun is a similar pistol shape, the steel body of thick 26mm; image 3 As shown, a gas inlet 11 and a liquid inlet 12 with a depth of 20 mm and two 8 internal threads are arranged side by side under the gun handle of the fire extinguishing gun body 1, and are connected to the gas-liquid supply package with the pressure gas input pipe 3 and the liquid input pipe 4. 2; at the inner end of the gas inlet 11 and the liquid inlet 12, open 40mm deep and have a diameter of 3mm for the first gas transmission hole 13 and the first liquid transmission hole 14, such as Figure 4As shown, the upper part of the gun body is provided with a second g...

Embodiment 2

[0026] Present embodiment 2 is that a kind of portable pulse jet fire extinguishing gun has larger size than embodiment 1, and can be used for putting out larger fires. The structure of fire extinguishing gun is identical with the structure of the fire extinguishing gun of embodiment 1.

[0027] In this embodiment, the fire extinguishing agent supply source and the pressure gas supply source are provided by the fire extinguishing agent supply pressure bag 2 . The fire extinguishing agent pressure supply package 2 includes a fire extinguishing agent bottle with relatively large pressure and volume. The outlet end of the pressure gas cylinder is connected with a pressure regulating valve and a pressure gauge, and is connected to the gas inlet 11 of the fire extinguisher 1 and the liquid through a pressure-resistant transmission pipe. The inlets 12 are connected. This relatively large dual-fluid jet fire extinguishing gun has a range of up to 4-6m and is very effective for outdo...

Abstract

The invention provides a double-fluid jet water mist fire gun belonging to the technical field of firefighting extinguishing apparatus. The fire gun is formed by a fire gun body (1), a gas-liquid supply bag (2), a pressure gas delivering tube (3) and a liquid delivery tube (4), wherein the fire gun body (1) is a steel body in gun shape; a gas incoming opening (11) and a liquid incoming opening (12) are formed side by side in the left and the right below the gun grip, and the gas delivery tube (3) and the liquid delivery tube (4) are connected to the gas-liquid supply bag (2); according to the invention, incipient fire in a spacecraft can be inhibited and extinguished by water mist ejected by the fire gun in the low-gravity environment, so that resource of extinguishing agent can be saved, and the fire gun is convenient to use and is flexible.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a mechanical double-fluid spray fine water mist fire extinguishing device in a microgravity environment, in particular to a double-fluid spray fine water mist fire extinguishing gun. Background technique [0002] Existing fire prevention technology in microgravity environment generally adopts spraying CO 2 Waiting for the fire extinguishing agent to extinguish the fire in the spacecraft destroys the air environment in the spacecraft and makes the astronauts unable to survive normally. CO 2 After the fire extinguishing agent is released, it will cause serious pollution to the environment in the spacecraft, and the air in the spacecraft needs to be replaced, which is a very difficult task. [0003] Explore the application of water mist fire extinguishing technology to spacecraft for fire prevention and control in spacecraft. Bubble atomization is an e...
