Fire Tube

Fire Detection Tube

The fire detection tube temperature sensing automatic fire extinguishing device is a simple, reliable, and timely independent fire detection and fire extinguishing device developed in China in recent years. This type of fire extinguishing device adopts a flexible and bendable fire detection tube as a fire detection and alarm component, and the fire detection tube can also be used as a pipeline for the delivery and discharge of fire extinguishing agents. The fire detection tube can be conveniently arranged near every potential fire source. Once a fire occurs, the fire detection tube is heated and ruptured, and the extinguishing agent is immediately released to extinguish the fire. It can make up for the deficiencies of the existing fixed gas automatic fire extinguishing devices, and is used for fire protection in places where pipe networks, nozzles or fire alarm systems cannot be installed, especially in small spaces and special environments.

Composition and principle: 1. Direct fire detection tube fire extinguishing device Mainly consists of fire extinguishing agent storage container, container valve, fire detection pipe, pressure gauge, one-way valve, pressure switch, alarm bell (Optional accessories) and special joints for fire detection pipes. The direct type is the fire detection tube in the fire extinguishing system. It is used as a fire detection component and at the same time The delivery part of the extinguishing agent, that is, once the fire detection tube detects a fire, it will directly release the extinguishing agent to extinguish the fire. Direct fire detection tube fire extinguishing device is mainly used for equipment with a certain enclosure, such as communication cabinets, transformer and distribution boxes, Fire fighting in the computer room.

2. Indirect fire detection tube fire extinguishing device It is mainly composed of fire extinguishing agent storage containers, container valves, fire detection tubes, release tubes, nozzles, pressure gauges, one-way valves, Composed of pressure switch, alarm bell (optional accessory) and special joint for fire detection pipe. The indirect type is the fire detection tube in the fire extinguishing system, which is only used as a fire detection component. When the fire detection tube detects a fire After that, it will activate the container valve on the fire extinguishing agent storage container, and the fire extinguishing agent is delivered by a special fire extinguishing agent release pipe Extinguishing. The indirect fire detection tube fire extinguishing device is mainly used for localized fire extinguishing of equipment without a certain enclosure. It can also be used to extinguish fires by flooding the entire room.

As a simple, low-cost and reliable independent automatic fire extinguishing system,
it does not require any power supply,
No need for special smoke and temperature fire detectors, no complicated electronic equipment and pipelines, and use of its own pressure storage, Relying on a charged fire detection tube and a set of fire detection bottle sets can detect and extinguish quickly, accurately and effectively The fire source integrates alarm and fire extinguishing to extinguish the fire in the initial stage. Can significantly reduce fire extinguishing equipment It can reduce the cost of fire extinguishing agent, reduce the cost of each fire extinguishing, and reduce the damage to personnel. With this device, the original protection of larger enclosed spaces can be changed to directly protect various smaller enclosed spaces.
Protect valuable equipment. Achieve close-range, point-to-point (fire extinguishing agent spray point and ignition point) fast fire extinguishing.

Applicable places:
Electromagnetic wave  room, microwave machine room, transformer room and
uninterruptible power supply room in the radio and television transmission tower.

2. Program control exchange room, control room and signaling transfer point room of communication system.
3. Power plant control room, electronic equipment room, computer room, relay room, transformer and distribution room; cable crossing,
Dense and intermediate joints and other parts.
