3. Structure and composition of fire extinguisher
The fire extinguisher is mainly composed of a cylinder assembly, a head assembly, a nozzle assembly, etc. The fire extinguishing agent is a water-forming foam premixed liquid, the driving gas is nitrogen, and its working pressure is 1.2MPa at room temperature.
Fourth, main performance characteristics
1. This series of fire extinguishers has the characteristics of high fire extinguishing efficiency and rapid fire extinguishing. The fire extinguishing agent contained in the interior has the advantages of stable performance, non-toxicity, pollution-free and easy storage.
2. The driving gas used is non-toxic and odorless, and it will not harm the human body after being sprayed.
3. The fire extinguisher bottle head valve is equipped with a pressure gauge, which has the effect of displaying its internal pressure, which is convenient for inspection and maintenance.
V. Scope of use
1. Suitable for extinguishing initial fires of flammable solids or liquids, but not fires with live equipment. They are widely used in oil fields, oil depots, ships, factories, shops and other places. They are fire-fighting equipment to prevent fires and protect people's lives and property.
2. The temperature range of use is: +5℃~+55℃.
