Ⅰ. Role of flame arrestor
A flame arrestor is a safety device used to prevent accidents such as fires and explosions. It prevents the flame from spreading or the burning area from expanding by isolating the flame and heat at the potential explosion hazard.
Ⅱ. the classification of flame arrestor
Flame arresters can be divided into various types according to their construction and use, including:
1. Mechanical flame arrestor: It realizes the role of firestopping through mechanical devices, and will automatically shut down or disconnect the equipment when fire occurs to prevent the fire from expanding.
2. Chemical flame arrestor: to stop the spread of fire through chemical action, by spraying the chemical reaction agent to the burning area to achieve the purpose of extinguishing the fire source or reducing the temperature.
3. Gas type flame arrester: reduce the oxygen content in the burning area by spraying inert gas to achieve the purpose of extinguishing the fire.
4. Water Mist Fire Arrestor: By spraying fine water mist and air mixture, the fire is controlled by cooling and absorbing heat.
Ⅲ. does the flame arrestor belong to the valve category?
Flame arrestor is generally not categorized as a valve, because it does not control the flow and pressure of fluid medium by opening or closing, but by isolating, cooling, eliminating combustible gases or chemical reactions, etc. to achieve the role of firestopping. In some cases, however, a flame arrestor can also be considered a valve-like device. For example, at the inlet and outlet of a storage tank, a flame arrestor is used to prevent flammable gases from entering or spewing out, in which case the flame arrestor can be regarded as a valve.
