Its working principle is introduced here: when a gas or powder starts a flame or explosion, the ultraviolet sensor will acquire the signal and sent it to the controller to produce the trigger voltage, and then the explosive suppressor will release a great number of gas promptly spraying dry powder extinguishing agents, which thereby form extinguishing agent smoke and effectively extinguish explosion flame. It is rapid and of strong antiinterference ability, high reliability and can be fixed easily. It is capable of effectively suppressing natural gas explosion in the simulative gas explosion test. It can be applied in CNG stations or other site where has explosive and combustible gas whereby to enhance the overall accident control ability.
