At present, this carbon dioxide cylinder is an important part used for carbon dioxide fire extinguishers, and it is a steel cylinder mainly used for carbon dioxide compressed gas.

Fire extinguishers have always played an important role in our lives, and today they have been developed for more than 100 years. With the continuous development of the times, people have begun to subdivide fire extinguishers more and more. According to the causes of fire, fire extinguishers have also developed more and more types. According to their moving methods, they can be divided into: portable and trolley; by drive The power source of fire extinguishing agents can be divided into: gas cylinder type, pressure storage type, chemical reaction type; according to the filled fire extinguishing agent, it can be divided into: foam, dry powder, haloalkane, carbon dioxide, clean water and so on.

Have you known about these kinds of fire extinguishers? Or have you ever touched it?

In fact, these different types of fire extinguishers are inseparable from these fire extinguishing methods:

The principle of the cooling fire extinguishing method is to spray the fire extinguishing agent directly on the burning object to reduce the temperature of the combustion below the ignition point and stop the combustion. Or spray the fire extinguishing agent on the material near the fire source so that it does not form a new fire point due to the heat radiation of the flame. The cooling fire extinguishing method is a main method for extinguishing fires. Water and carbon dioxide are commonly used as extinguishing agents to cool down and extinguish fires. The fire extinguishing agent does not participate in the chemical reaction during the combustion process during the fire extinguishing process. This method is a physical fire extinguishing method.

Isolation fire extinguishing method is to isolate or remove the burning material from the surrounding unburned combustible materials, interrupt the supply of combustible materials, and stop the combustion due to lack of combustible materials.

Asphyxiation is a fire extinguishing method that prevents air from flowing into the combustion zone or dilutes the air with a non-combustion zone or with non-combustible materials, so that the combustion cannot get enough oxygen to extinguish the fire. At present, this carbon dioxide fire extinguishing method adopts the suffocation fire extinguishing method. By spraying non-combustible gas or non-combustible liquid, carbon dioxide is sprayed into the area of combustion materials or on the combustion materials to extinguish the fire.

This fire extinguishing method well controlled the spread of the fire and played an important role in extinguishing the initial fire of valuable equipment, archives, instruments, electrical equipment below 600 volts and oil.
