I. System Introduction
QME series high-pressure carbon dioxide automatic fire extinguishing system was independently developed by Jiangxi Tsinghua Industrial Co., Ltd. The product performance complies with the "General Technical Conditions for Carbon Dioxide Fire Extinguishing Systems and Components" (GB16669-2010) and ISO similar product standards. And the refractory component quality supervision and inspection center passed the type inspection, the product passed the ISO9001 international quality system certification, and China Ping An Insurance Co., Ltd. assumes insurance.
System fire extinguishing agent Carbon dioxide is a clean fire extinguishing agent. It is a colorless, odorless and dry inert gas. It completely vaporizes after fire extinguishing. There is no residue, no cleaning, and no water damage. Contains corrosive, non-conductive and non-polluting food, so it can be safely used in places such as precision equipment and valuables.
The system is mainly composed of automatic fire alarm control system, fire extinguishing agent storage container, container valve, starter bottle, starter valve, selection valve, check valve, pressure signal device, weighing device, frame, sprinkler, pipe system, etc. The system has the functions of automatic fire detection, automatic alarm and control of linkage equipment, and automatic fire extinguishing. In emergency situations, electrical manual and mechanical emergency manual methods can be used to start fire extinguishing.
According to the requirements of the system, the system can be composed of a unit independent fire extinguishing system and a combined distribution fire extinguishing system. At the same time, it can be suitable for full flood protection and local protection fire suppression. This series of products have the characteristics of complete functions, accurate and reliable work, convenient operation and maintenance. Can be widely used in flammable liquid storage areas, important parts of machinery and equipment that are prone to fire, computer and electronic equipment rooms, libraries, archives, treasures, transformer rooms, aircraft garages, kitchens, and smoke exhaust pipelines and other protective areas .
Carbon dioxide automatic fire extinguishing system consists of: gas fire alarm control system, fire detection system, fire extinguishing drive panel, sound and light alarm device, vent valve light, emergency start, stop button, fire extinguishing agent storage bottle, container valve, high pressure hose, selection valve, It consists of one-way valve, pneumatic control valve, pressure switch, nozzle, starting cylinder, pipeline and other major equipment. Can be composed of unit independent system or combined distribution system and other forms. Implement fire protection for single or multiple zones.
Widely used in power plants, power stations, rolling mills, printing presses, immersion oil tanks, paint making, pharmaceuticals and other important parts that are prone to fire, as well as computer rooms, libraries, archives, treasures, telecommunications centers and other places.
According to the characteristics of the carbon dioxide fire extinguishing agent and the fire extinguishing method, the carbon dioxide fire extinguishing system can be used to extinguish:
① Gas fire that can cut off the gas source before extinguishing the fire;
② Liquid fire or meltable solid fire such as paraffin and asphalt;
③ Solid surface fires and deep solid fires such as cotton wool, fabrics, and paper;
④ Electrical fires, such as transformers, oil switches, and electronic equipment.
The carbon dioxide fire extinguishing system must not extinguish the following fires:
① Fire of chemical products containing oxidants such as nitrocellulose and gunpowder.
② Potassium, sodium, magnesium, titanium, zirconium and other lively metal fires.
③ Fires of metal hydrides such as potassium hydride and sodium hydride.
