Three technologies for preventing ex- plosion risk of smart gas meters are described, inclu- ding gas meter sealing technology and safety cut-off technology, current control technology, motor circuit and gas isolation technology. Gas meter sealing tech- nology is a technology to prevent and impede gas meter leakage causing explosion accident, including the gas meter overall sealing technology, the output shaft seal- ing technology, the insulation and sealing technology of built-in cut-off valve control line and the built-in cut- off valve sealing technology. The safety cut-off technol- ogy is a technology to prevent and impede user abnor- mal use or sudden disaster causing leakage explosion accident, including the abnormal flow safety cut-off technology, the abnormal pressure safety cut-off tech- nology, the earthquake perception safety cut-off tech- nology, the gas leakage safety cut-off and fire safety cut-off technology. The current control technology is a technology to prevent and impede the gas meter own circuit spark ignition of gas accumulated in its sur- rounding environment, including the low-power valve control technology, the low-power communication tech- nology and the low-power controller technology. The motor circuit and gas isolation technology are the tech- nology to prevent and impede the control valve motor circuit spark ignition of gas-air mixture formed within gas meter,namely the insulation protection technology. The suggestion of legalizing the information security of smart meter is put forward.
