Product Types
Automatic fire extinguishing systems with fire detector tubes can be divided into direct and indirect fire detector tube systems based on their system structure.
1. Direct Temperature-Sensitive Self-Activating Fire Extinguishing System
Components
The system primarily consists of a container containing fire extinguishing agent, a container valve, a pressurized fire detector tube that releases the agent and has fire detection capabilities, a pressure gauge, a check valve, a pressure switch, an alarm, and a dedicated connector for the fire detector tube.
The fire detector tube is a high-tech non-metallic composite product. It combines long-term leak resistance, flexibility, and effective temperature sensitivity. After pressurization, it ruptures within a certain temperature range to release the extinguishing agent or transmit a fire signal.
Working Principle
The fire detector tube is connected to the fire extinguishing agent container via a container valve and is positioned above the most likely fire source to detect it. When a fire occurs, the fire detector tube softens and ruptures at the highest point of heat exposure. The pressure drop in the tube activates the container valve, releasing the fire extinguishing agent through the rupture hole in the fire detector tube to extinguish the fire. At the same time, an alarm bell sounds, alerting the user that the system has been activated. The user must then verify the extinguishing process, repair the system, and refill the extinguishing agent.
2. Indirect Temperature-Sensing Self-Activating Fire Extinguishing Device
Components
This device primarily consists of a container containing the extinguishing agent, a container valve, a pressurized fire detection tube, a release tube, a nozzle, a pressure gauge, a check valve, a pressure switch, an alarm bell, and a dedicated connector for the fire detection tube.
Operating Principle
The fire detection tube is connected to the extinguishing agent container via the container valve and positioned above the most likely fire source to detect it. Upon encountering a fire, the fire detection tube softens and ruptures at the highest point of heat exposure. The pressure drop in the tube activates the container valve, releasing the extinguishing agent through the release tube to the nozzle, extinguishing the fire. At the same time, an alarm bell sounds, alerting the user that the system has been activated. The user must then verify the extinguishing process, repair the system, and refill the extinguishing agent.
System Application Scope
The temperature-sensing automatic fire extinguishing system solves the long-standing fire prevention problem in fire-prone spaces such as electrical equipment, control boxes, and distribution boards—a challenge that has long affected the fire protection industry. Currently, this system has been widely used in power plants, telecommunications, broadcasting, petrochemical, and railway systems in China, accumulating a wealth of successful experience.
1. Suitable Firefighting Locations
- Microwave rooms, decimeter wave rooms, meter wave rooms, substations, and uninterruptible power supply rooms within radio and television transmission towers
- Programmable switching rooms, control rooms, and signaling transfer point rooms within communication systems
- Control rooms, electronic equipment rooms, computer rooms, relay rooms, and substations in power plants
- Areas where cables cross, are densely packed, and where intermediate joints are located
- Substation cabinets, elevator control cabinets, and cable trays with trough boxes or bridges
- Other locations with relatively enclosed enclosures for special or critical equipment
2. Applicable Fire Types
Heptafluoropropane-filled automatic fire extinguishing devices with fire-detecting tubes can be used to extinguish the following fires:
- Fires involving combustible gases where the gas source can be shut off before extinguishing the fire
- Fires involving Class A, B, or C liquids or meltable solids such as paraffin and asphalt
- Fires involving solid surfaces and deep-seated fires involving some solid materials such as cotton, fabric, and paper
- Electrical fires
3. Prohibited Fire Types
Heptafluoropropane-filled automatic fire extinguishing devices with fire-detecting tubes must not be used to extinguish the following fires:
- Fires involving chemicals containing oxidants, such as nitrocellulose and gunpowder
- Fires involving reactive metals such as potassium, sodium, magnesium, titanium, and zirconium
- Fires involving metal hydrides such as potassium hydride and sodium hydride
