Abstract:
     The present invention relates to an igniter of priming system, in particular, it relates to an igniter for lighting condensed fire explosive powder under the high-pressure environment. Said invention includes an igniter made of metal material, said igniter has a hollow cavity, an igniter sealed metal cone which is placed in the igniter hollow cavity and is connected with said igniter and an igniting device component connected with said igniter. In said invention said igniting device seat can be separated into two portions which are not communicated mutually by means of igniting primer, so that the interior of igniter communicated with interior of igniting primer is atmospheric environment pressure, therefore it is convenient for lighting ignition powder. Said invention adopts the metal tube with good heat conductivity as igniting primer, so that it not only raises the ignition temperature, but also ensures enough ignition area.
