Indirect fire suppression system

1. The Flame Detection and Automatic Fire Extinguishing Device with a Flexible Non-metal Probe Tube is a more scientifically and reasonably designed fire extinguishing system. It utilizes a flexible non-metal probe tube for fire detection and extinguishing agent discharge, operates without any power source, and combines fire detection with extinguishing capabilities. It is a product encouraged by the National Development and Reform Commission for the industrial upgrade during the 13th Five-Year Plan period.

2. The flame tube-type automatic fire extinguishing device does not require any power or traditional electrical control for fire extinguishing controllers, fire detectors, and relies entirely on the material of the flame tube itself for accurate physical detection of fires to implement extinguishing. Therefore, it avoids false alarms and malfunctions caused by electromagnetic interference, smoke and dust, oil stains, humidity, and human errors, making it more convenient, stable, and reliable.

3. The flame-detecting and automatic fire extinguishing device with a flexible non-metallic probe tube can be installed close to the flammable parts inside the equipment (where traditional fire protection systems' detection and extinguishing agent nozzles are typically mounted at the top of the building, far from the actual fire source), enabling timely fire detection and precise, rapid point-to-point extinguishing, making it a true early fire suppression system.

4. The fire-tube type temperature-sensing automatic fire extinguishing system transforms the traditional gas fire extinguishing system from a full flooding method for the entire building interior to a localized flooding method for only the fire-prone equipment within the building. This results in a reduction of fire extinguishing agent usage by over 80%, and eliminates the need for complex piping networks, cylinder storage rooms, and electronic control equipment. It also significantly reduces the weight and space occupied by the fire extinguishing system, as well as the environmental and health hazards posed by the extinguishing agent.

5. Fire-tube type automatic fire extinguishing devices, classified according to the functions of the fire-tube, can be divided into two types: "Direct Fire Extinguishing Devices" and "Indirect Fire Extinguishing Devices." Devices that combine both fire detection and extinguishing agent discharge functions are referred to as "Direct Fire Extinguishing Devices"; those with only fire detection functions, with the extinguishing agent discharge completed by a separate release tube, are categorized as "Indirect Fire Extinguishing Devices."

6. The direct extinguishing device in the flame-detecting pipe-type automatic fire extinguishing system is composed of flexible flame-detecting pipes installed inside the protected equipment. In the event of a fire, the flame-detecting pipe closest to the fire source heats up, softens, and bursts, causing a loss of pressure inside the pipe. This pressure drop opens the valve of the container, releasing the fire extinguishing agent from the container bottle through the burst pipe opening, directly spraying towards the fire source and extinguishing it quickly at the initial stage. Mainly used to protect equipment with a shell volume of 6m³ or less.

7. Indirect fire extinguishing device in a flame detection pipe-type automatic fire extinguishing system. The flexible flame detection pipe is arranged in the fire detection area. Once a fire occurs, the flame detection pipe closest to the fire source heats up, softens, and bursts, causing a loss of pressure inside the pipe. This pressure drop opens the container, which is closed by pressure balance, and the fire extinguishing agent inside the container is released through a separate release pipe and sprayed into the protected space through nozzles to extinguish the fire. Mainly used for protecting spaces below 60m³ and equipment without an enclosure.

8. The flame tube type automatic fire extinguishing device with temperature sensing is suitable for microwave rooms, decimeter wave rooms, transformer rooms, and uninterruptible power supply rooms within broadcast and television transmission towers.

9. The programmed exchange rooms, control rooms, and signaling transfer points of the fire tube type automatic fire extinguishing device communication system, railway control rooms, and signal stations.

10. The fire tube type temperature-sensing automatic fire extinguishing device is suitable for power generation equipment such as thermal, hydropower, and wind power plants, various control rooms, electronic equipment rooms, computer rooms, relay rooms, transformer substations (cabinets), transformers, cable intersections, elevator control cabinets, and槽盒-lined wire and cable channels or bridge structures.

11. Fire tube type automatic fire extinguishing devices with temperature sensors are suitable for CNC machine rooms, precision equipment, vehicles such as cars, trains, subways, and ships.

12. The flame tube type automatic fire extinguishing device with temperature sensing is suitable for commercial kitchens, library facilities, flammable goods storage, and other types of warehouses, as well as for special or critical equipment cabinets in various locations.

13. The flame detection and automatic fire extinguishing system consists of a pressure container filled with extinguishing agent, container valves, and fire detection tubes or release pipes capable of releasing the extinguishing agent.

14. Install the flame tube type temperature-sensing automatic fire extinguishing device above or near the potential fire source. Simultaneously, rely on the multiple detection points (linear) along the flame tube for detection. Upon ignition, the flame tube softens at the heated temperature and releases the extinguishing medium either through the flame tube itself (direct system) or through nozzles (indirect system) into the protected area.

15. The Fire Detection Tube-type Automatic Fire Extinguishing Device is a new variety developed in the high-tech field, a high-tech non-metallic synthetic product. It combines long-term leakage resistance, flexibility, and effective temperature sensitivity into one, and within a certain temperature range, it can discharge fire extinguishing medium or transmit fire signals.

16. The fire probe-style automatic gas fire extinguishing system, commonly known as "fire probe," is a small, fixed automatic gas fire extinguishing device; it is an automatic gas fire extinguishing system that accurately detects the fire source, extinguishes the fire at its inception, and combines detection and extinguishing into one.

17. The Flame Detection Tube Style Automatic Fire Extinguishing System is an automated gas fire suppression device that offers targeted, point-to-point, and close-protection to areas prone to fires or critical facilities.

18. The probe pipe type automatic fire extinguishing device is a simple-to-install, versatile, battery-free, and highly reliable automatic gas fire extinguishing system.

19. The fire probe of the automatic fire extinguishing system is a flexible material, unaffected by any position, and can be inserted into various narrow and complex flammable spaces or equipment, which is something that other fire extinguishing facilities cannot achieve.

20. The flame detection and automatic fire extinguishing system with a probe pipe is equivalent to a linear detector, where any point can detect a fire source. It bursts and releases the fire extinguishing medium near the fire source, close to the protected object. Combining detection and extinguishing, the system responds quickly, capable of extinguishing fires at their nascent stage, effectively reducing economic losses caused by fires, and facilitating rapid production recovery.

21. The flame tube type automatic fire extinguishing device operates without power, is not affected by electromagnetic interference, vibration, or impact, and is not weakened by smoke, dust, humidity, or other environmental factors, preventing false operations. It is easy to install and maintain with low operating costs. Not a total flooding system for building spaces, it won't harm personnel during release, making it suitable for unmanned surveillance and key equipment or areas requiring protection.
