(gas fire extinguishing system) 气体灭火系统 Principles of gas fire extinguishing system The gas fire extinguishing system is connected to the automatic alarm system. When the automatic alarm system receives the two level alarm (simultaneously receives the smoke detector and the temperature sensor, calls the two level alarm), will send asignal to the gas fire extinguishing system's control panel. After the gas disk receives the signal, it will command to start the solenoid valve at the top of the gas cylinder. The solenoid valve acts to open the valve at the top of the cylinder and release the gas in the cylinder. Simply put, that's it. In fact, the gas reserves are generally composed of several cylinders to protect (because the gas inside the cylinder, one cannot reach the concentration of the fire out), that is to say, when the gas barried commands to start acylinder, the cylinder in the gas discharge, the other cylinder valve open top. To start the other cylinders. This is used to protect the gas cylinders in this area all have blow out. This will extinguish the fire. It is through the inhibition of chemical reaction to the burning fire area release alarge number of alkyl halides or "SDE" or carbon dioxide extinguishing agent or reducing oxygen and temperature in the air containing flammable area, the fuel combustion termination or gradual suffocation. The system is mainly used to avoid water important places, such as substation, printing workshop, electronic computer room and important library and other occasions. Carbon dioxide is basically the same as "SDE" and halon extinguishing system. But the cost is low, is 1/30 of halogenated alkane. Compared with water fire extinguishing agent, carbon dioxide has the advantages of no pollution, no water stain, no electricity and so on. Therefore, it is widely used in the fixed fire extinguishing facilities for modern electric fire protection. At present, the amount of fire extinguishing system is only higher than that of water spray system, but higher than that of halon fire extinguishing system.
