Explosion-proof solenoid valve national standard:

“ExdⅠ/ⅡBT3”It is a common symbol for explosion-proof solenoid valveslet’s split it up:“Ex”means explosive,is a common symbol.“d” indicates that the secondary explosion-proof type is “flameproof type d”.“Ⅰ” or “Ⅱ”The two identities areClassification of electrical equipment,inⅠ Electrical equipment for coal mines,Ⅱ is equipment for explosive gas atmospheres other than coal mines. Among them, Class II flameproof “d” and intrinsically safe “i” electrical equipment are further divided into Class IIA, II B and II C.“T3”expresstemperature group.
China’s explosion-proof grade standard is “GB3836.1-2000 Electrical Equipment for Explosive Gas Atmospheres”, which will be supplemented or modified by the following special standards for explosion-proof types.
GB3836.2 Electrical apparatus for explosive gas atmospheres Part 2: Flameproof type “d”
GB3836.3 Electrical apparatus for explosive gas atmospheres Part 3: Increased safety type “e”
GB3836.4 Electrical apparatus for explosive gas atmospheres – Part 4: Intrinsically safe type “i”
GB3836.5 Electrical apparatus for explosive gas atmospheres – Part 5: Positive pressure type “p”
GB3836.6 Electrical apparatus for explosive gas atmospheres – Part 6: Oil-filled type “O”
GB3836.7 Electrical equipment for explosive gas atmospheres – Part 7: Sand-filled type “q”
GB3836.9 Electrical apparatus for explosive gas atmospheres – Part 9: Encapsulation type “m”

GB7957 Mining helmet lamp
The above national standards for explosion-proof solenoid valves areDetonator, detonator testerAnd medical electrical equipment, ignition circuit testmiddlenot applicable.
