Embodiment 1

[0020] Such as figure 1 As shown, the present invention provides a dual-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 pressurized gas input pipe 3, and a liquid input pipe 4 connected together. The fire gun body 1 of the fire gun is a steel body with a shape similar to a pistol and a thickness of 26mm; Figure 4 As shown, below the handle of the fire extinguishing gun body 1, a gas inlet 11 and a liquid inlet 12 with a depth of 20 mm and 8 internal threads are arranged side by side, and the pressure gas input pipe 3 and the liquid input pipe 4 are connected to the gas-liquid supply package. 2; The first gas transmission hole 13 and the first liquid transmission hole 14 with a depth of 40mm and a diameter of 3mm are opened straight ahead at the inner ends of the gas inlet 11 and the liquid inlet 12, such as Figure 5 As shown, the upper part of the gun body is provided...

Embodiment 2

[0026] This embodiment 2 is a portable pulse jet fire extinguishing gun with a larger size than the embodiment 1, and can be used to extinguish larger fires. The structure of the fire extinguishing gun is the same as that of the first embodiment.

[0027] The fire extinguishing agent supply source and the pressure gas supply source in this embodiment are provided by the fire extinguishing agent supply pressure package 2. The fire extinguishing agent supply pressure package 2 includes a fire extinguishing agent bottle with a 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 and liquid of the fire extinguishing gun 1 through a pressure transmission tube. The inlet 12 is connected. This larger dual-fluid jet fire extinguishing gun has a range of 4-6m, which is very effective for outdoor fire extinguishing. It can be used to extinguish large-area ...

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 extinguishing equipment, and specifically relates to a mechanical two-fluid jet water mist fire extinguishing device in a microgravity environment, in particular to a double fluid jet water mist fire extinguishing gun. Background technique [0002] Existing fire prevention technology in microgravity environment generally adopts CO injection 2 Waiting for the fire extinguishing agent to extinguish the fire in the spacecraft destroyed the air environment in the spacecraft and made 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. It is necessary to replace the air in the spacecraft, which is a very difficult task. [0003] Explore the application of water mist fire extinguishing technology to spacecraft for fire prevention in spacecraft. Bubble atomization is an effective method for generating ...
