The classification of explosive gas environmentally hazardous areas is a continuous or long-term environment in which explosive gas mixtures occur.
Zone 1 : An environment in which explosive gas mixtures may occur during normal operation.
Zone 2 : An environment in which an explosive gas mixture is unlikely to occur during normal operation or in an environment where only a short-lived explosive gas mixture is present. Control Valve, Flow Control Valve, Hydraulic Control Valve, Proportional Directional Control Valve
Zone 0 : Generally only exists in the internal gas space of closed containers, storage tanks, etc. In the actual design process, Zone 1 is also rare, and most of them belong to Zone 2 .
 explosion-proof electrical equipment is divided into two categories:
Class I Electrical equipment for underground coal mines
Class II electrical equipment used in places other than mines
1.3 , Class II electrical equipment, according to its application to the explosive gas mixture Zui large test safety clearance or zui small ignition current ratio, divided into IIA , IIB , IIC three categories; according to its high surface temperature is divided into six groups of T1-T6 . (IIC is the flameproof type of Zui advanced, can cover the application range of IIA , IIB
1.4 . Explosive gas mixtures are grouped according to ignition temperature, see Table 1 .
1.5 . Explosive gas mixture, according to its large test safety clearance (MESG) or zui small ignition current ratio (MICR) , see Table 2 .
