For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0032] Please refer to Figs. 1-6 The embodiment of the application provides a kind of external storage pressure heptafluoropropane fire extinguisher, including fire extinguishing agent bottle group 1, fire extinguishing pipeline 2, pressure gas bottle group 3, drive gas bottle group 4, wherein, fire extinguishing agent bottle group 1 includes multiple fire extinguishing agent bottles, fire extinguishing agent bottle is equipped with liquid fire extinguishing agent;Fire extinguishing pipeline 2 input end is connected with the outlet of fire extinguishing agent bottle, and fire extinguishing pipeline 2 another end is laid in fire protection area;Pressure gas bottle group 3 includes multiple pressure gas bottles and container valve 31 arranged on the inlet of pressure gas, and pressure gas bottle is filled with high-pressure gas, and the outlet of pressure gas bottle is connected with the inlet of fire extinguishing agent bottle;Drive gas bottle group 4 includes multiple drive gas bottles and gas bottle solenoid valve arranged on drive gas bottle, and drive gas bottle is equipped with high-pressure gas, and drive gas bottle outlet is connected and controls container valve 31 by drive pipeline;Gas bottle solenoid valve and fire alarm controller in fire protection area are electrically connected.

[0033] The principle of this application is that when the fire alarm controller detects a fire in the fire protection zone, it controls the opening of the solenoid valve of the gas cylinder, so that the high-pressure gas in the driving gas cylinder enters the container valve 31 through the driving pipe, and controls the opening of the container valve 31, which in turn opens the container valve 31 of the pressurized gas cylinder. The high-pressure gas in the pressurized gas cylinder enters the extinguishing agent cylinder and is discharged from the outlet of the extinguishing agent cylinder. Under the siphon effect, it is carried out from the extinguishing agent cylinder and enters the fire extinguishing pipe 2, and flows rapidly along the fire extinguishing pipe 2 to the fire protection zone, thereby extinguishing the fire in the fire protection zone.

[0034] Specifically, the extinguishing agent in extinguishing agent cylinder group 1 is heptafluoropropane; the high-pressure gas in the pressurized gas cylinder and the driving gas cylinder can be nitrogen.

[0035] like Figs. 1-2 As shown, in one embodiment, a liquid one-way valve 5 is also included, which is disposed at the outlet of the extinguishing agent cylinder (located between the extinguishing agent cylinder and the extinguishing pipeline 2). The liquid one-way valve 5 restricts the flow direction of the extinguishing agent, so that the extinguishing agent in the extinguishing agent cylinder can only flow to the extinguishing pipeline 2 and will not flow back into the extinguishing agent cylinder.

[0036] In one embodiment, a manifold 6 is also included, which is disposed between the extinguishing agent cylinder and the extinguishing pipeline 2 to connect the extinguishing agent cylinder and the extinguishing pipeline 2. The manifold 6 is used to transport the extinguishing agent output from the extinguishing agent cylinder to the extinguishing pipeline 2 for collection, thereby connecting the extinguishing pipeline 2.

[0037] In one embodiment, a gas check valve 7 is further included, which is disposed at the inlet of the extinguishing agent cylinder. The gas check valve 7 is made of materials such as copper alloy or stainless steel, and its surface is passivated. The gas check valve 7 is disposed at the inlet of the extinguishing agent cylinder and is used to control the flow direction of the pressurized gas output from the pressurized gas cylinder.

[0038] In one embodiment, a high-pressure hose 8 is also included, which is disposed between the container valve 31 and the gas check valve 7. The high-pressure hose 8 consists of a steel wire braided hose and a hose connector, and serves as a pressure buffer.

[0039] In one embodiment, the system further includes an atomizing nozzle 9, which is disposed at one end of the fire extinguishing pipe 2 near the fire protection zone. The atomizing nozzle 9 is used to atomize the extinguishing agent output from the fire extinguishing pipe 2, so that the extinguishing agent can be more evenly dispersed to the fire scene, thereby improving the extinguishing range and effectiveness.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
