Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to an externally pressurized fire extinguishing device. Background Technology

[0002] Gas extinguishing systems are an important type of fire suppression system. They primarily suppress fires by releasing specific extinguishing gases, making them particularly suitable for locations where water-based fire suppression is unsuitable, such as electronic equipment rooms, computer rooms, libraries, and museums. Gas extinguishing systems typically use a combination of extinguishing agents and high-pressure gases to extinguish fires. After a fire occurs, a temperature-sensitive triggering mechanism activates the valve of the high-pressure gas container, releasing the high-pressure gas, which is then mixed with the extinguishing agent, at high speed to extinguish the fire. Existing temperature-sensitive triggering mechanisms typically employ either electromagnetic or mechanical activation. Electromagnetic activation is fast but cannot be activated when power is off, while mechanical activation is stable but slower. Utility Model Content

The fire extinguishing device is installed outside the protected area to achieve long-distance fire extinguishing without occupying space within the protected area. One end of the nozzle 205 that is connected to the agent channel 202 is provided with a working diaphragm 207. The working diaphragm 207 isolates the nozzle 205 from the outlet of the agent channel 202. When the pressure of the agent bottle 2 reaches the working pressure, the extinguishing agent and high-pressure gas pass through the working diaphragm 207.

[0029] In this embodiment, a signal feedback device 206 is provided above the gas pipeline 203. The signal feedback device 206 has a valve chamber that communicates with the gas pipeline 203.

The upper end of the compression spring 311 is sleeved on the protrusion 309 and abuts against the bottom of the movable block 308. When working, the glass ball 307 breaks, the movable block 308 loses support, and the compression spring 311 pushes the movable block 308 to move.

[0033] The external pressure fire extinguishing device of this embodiment uses mechanical drive and electromagnetic drive to start the gas cylinder container valve 101. It can work stably under power-on or power-off conditions. When powered on, the external temperature sensor sends an electrical signal or the solenoid valve 106 is activated manually, which can quickly start the gas cylinder container valve 101 to extinguish the fire. In the event of power failure or if the controller does not send a signal in time, when the temperature of the temperature sensing component 3 reaches a certain value, it can push the valve core 1062 of the solenoid valve 106, thereby activating the gas cylinder container valve 101 to extinguish the fire. The two starting methods do not affect each other, which improves the working stability of the fire extinguishing device.
