fire detection tube automatic fire extinguishing system

Description：

      The fire detection device is a simple, low-cost and highly reliable independent automatic fire extinguishing system. It does not require any power supply, special smoke and temperature detectors, or complicated equipment and pipelines. It uses its own stored pressure. When the fire detection tube ruptures due to heat, the fire extinguishing agent is immediately released to extinguish the fire.

Working principle: 

       The fire detection tube fire extinguishing system is composed of a pressure vessel filled with fire extinguishing agent, a container valve, and a fire detection tube and/or a release tube that can release the fire extinguishing agent. The fire detection tube is placed near or above the most likely place where the fire source occurs, and at the same time, detection is carried out by relying on many detection points (linear) along the fire detection tube. Once a fire occurs, the fire detection tube is softened and exploded at the highest temperature, and the fire extinguishing medium is released to the protected area through the fire detection tube itself (direct system) or the nozzle (indirect system). Among them, the fire detection tube is a new variety developed in the high-tech field and is a high-tech non-metallic synthetic product. It combines long-term leakage resistance, flexibility and effective temperature sensitivity, and explodes within a certain temperature range to spray fire extinguishing media or transmit fire signals.

Fire detection tube fire extinguishing system features:

1. When a fire occurs, the fire detector will detect the fire and the fire detection tube automatic fire extinguishing system will automatically work, which can extinguish the fire in the shortest time and minimize the loss for customers.

2. The fire detection tube automatic fire extinguishing system can also work normally during a power outage. The fire detection tube automatic fire extinguishing system has a built-in emergency power supply. When there is a power outage or the power is cut off due to a main power failure, the fire detection tube automatic fire extinguishing system automatically switches to the emergency power supply and works normally. In an emergency state, the fire detection tube automatic fire extinguishing system can also automatically respond to fire.

4. Low cost and safe to use. The traditional large-space full flooding fire extinguishing method is changed to a local full flooding or local fire extinguishing method targeting the potential fire point. It is closest to the protected object and has high fire extinguishing efficiency.
The amount of fire extinguishing agent is reduced by more than 80% compared with the traditional method. It is more environmentally friendly and safer for personnel. The design and installation are simple, do not occupy the user's limited space, and no additional gas cylinder room is required.

Classification of fire detection tube automatic fire extinguishing system:

1. Direct fire detection tube automatic fire extinguishing system
The direct fire detection tube automatic fire extinguishing system is connected to the fire extinguishing agent container through the container valve to detect the fire source. When encountering a fire, the fire detection tube explodes. The pressure drop in the fire detection tube is used to start the container valve, and the fire extinguishing agent is transported to the original fire detection tube explosion hole for spraying through the conversion joint installed at the outlet of the container valve.
The direct fire detection tube automatic fire extinguishing system can be divided into: CO2 direct fire detection tube fire extinguishing device, FM200 direct fire detection tube fire extinguishing device, NOVEC1230 direct fire detection tube fire extinguishing device and other clean gases according to the type of stored fire extinguishing agent.

2. Indirect fire detection tube automatic fire extinguishing system: Unlike the direct type, the indirect device detects fire through smoke, temperature sensors, etc. When a fire signal is detected, it will trigger the control system to start the indirect fire detection tube automatic fire extinguishing system. This method does not directly detect the fire source through the fire detection tube.
The indirect fire detection tube fire extinguishing device detects fire signals through the fire detection tube. When a fire occurs, the heat radiation of the flame will cause the trigger in the fire detection tube to react chemically, thereby causing a change in the pressure in the fire detection tube. When the pressure reaches a certain value, the signal line in the fire detection tube will be triggered and send a fire signal to the controller.
The controller receives the fire signal and issues a command
The controller is the core part of the system. When receiving a fire signal, the controller will first process the signal to determine whether it is a real fire signal. If so, it will issue a command to start the fire extinguishing system. In addition, the controller can also perform manual confirmation, automatic alarm and other functions.
Fire extinguishing control valve starts the fire extinguishing device
The fire extinguishing control valve is a key part of the fire extinguishing system. It can control the supply and injection of the fire extinguishing agent to achieve the effect of fire extinguishing. When the controller issues a command, the fire extinguishing control valve will be activated to transport the fire extinguishing agent to the sprinkler and spray it to the fire scene.
