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.

当发生气体燃烧、爆炸时，紫外传感器接收火焰信号，传送至控制器，控制器产生触发电压，使抑爆器的产气剂释放出大量气体，驱动快速喷撒出干粉灭火剂，形成足够浓度的灭火剂粉雾体，有效扑灭爆炸火焰，具有动作速度快、抗干扰能力强、可靠性高、安装使用方便等优点，在天然气模拟爆炸试验中能有效抑制天然气爆炸，可用于CNG加气站或其他燃烧爆炸性气体场所，提高其整体防灾抗灾能力。

Unlike silver salt, platinum compounds are not affected by light; the process depends on the fact that the composition of certain iron salts is altered by the action of ultraviolet light in proportion to the length and intensity of exposure.
