The automatic fire extinguishing device for kitchen equipment, referred to as the kitchen self-extinguishing device for short, code name: cmjs, is an effective self-starting fire extinguishing device for accidental fire in the oil pan of the commercial kitchen stove, which can quickly extinguish the fire in the oil pan, open the water flow valve at the same time, and achieve the effect of cooling down and preventing re-ignition. It is a kind of equipment with many fire extinguishing options in commercial kitchens on the market at present.
Fire extinguishing device of kitchen equipment
Nitrogen driving device: driving agent spraying
Edible oil fire extinguishing agent storage device: environment-friendly fire extinguishing agent, 3-8 seconds fire extinguishing
Temperature sensing device: the temperature rises rapidly after fire, exceeding the normal temperature range, and the temperature sensing piece melts, triggering the fire extinguishing device
Pipeline spraying device: spraying fire extinguishing agent, and simultaneously triggering the water flow valve to cool down after fire extinguishing
. It will catch fire and burn at about 4 degrees Celsius, and the flame will rapidly increase the temperature in the upper smoke range. When the temperature of the temperature-sensitive plate placed above the pot range in the smoke hood reaches 183 degrees, the temperature-sensitive plate will fuse, and the high-pressure nitrogen device will be triggered to open through the transmission of steel wires, and the nitrogen bottle will release the pressure of 12Mpa, and the fire extinguishing agent will be driven to spray through the pressure reducing valve of the device, and the fire can be extinguished in 1-3 seconds. The medicine is sprayed quickly, and it takes only 1-2 seconds from the melting of the temperature sensor to spraying the special medicine.

iv. is the equipment qualified for fire protection?
product standards and technical requirements: GA498-212 boxes have unique fire protection numbers and two-dimensional codes to check.
fire certification mark
v. model differentiation
Common models of kitchen fire extinguishing devices are CMJS9-1-CD and CMJS18-2-CD. Many people don't know the meaning of the models, but they don't know that the models are scribbled casually, and they are based on standards. According to product standards and technical requirements: GA498-212, cm is the code name of kitchen equipment fire extinguishing devices. D is electric start, which is combined according to the type of equipment. S has the function of water cooling. If there is no water cooling, it will not be written. The first set of numbers is the number of nozzles, the second set is the number of fire extinguishing agent containers, and the last set of letters is reserved for enterprises to customize, generally abbreviated as the initials of enterprise brand names.
