Abstract
The invention discloses a separable ignition device which comprises ignition composition (6) and also comprises an fire transferring tube (2), an ignition tube (3), an ignition composition box (4) and an insensitive ignition head (1), wherein one end of the fire transferring tube (2) is arranged on the insensitive ignition head (1) in coaxial threaded connection; the axis of the fire transferring tube (2) is vertical to the axis of the ignition tube (3); the other end of the fire transferring tube (2) is in coaxial threaded connection with the side wall of the ignition tube (3); and the ignition composition (6) is arranged at the inner part of the ignition tube (3). When the ignition device works, the insensitive ignition head (1) is detonated and ignited by utilizing ignition current; the generated fire is transferred into the ignition tube (3) through the fire transferring tube (2) to ignite the ignition composition (6) in the ignition tube (3); the ignition composition (6) rapidly burns beginning from the outside surface; the ignition composition box (4) is burned out by the fire; and main charge (5) is ignited. The separable ignition device has the advantages that the safety and the stability of the system are enhanced, and the sufficiency of main charge ignition is realized.
Description
Technical field
The present invention relates to a kind of igniter, particularly a kind of detachable igniter.
Background technology
The igniter that the guided missile rocket uses mainly contains three types of igniter head, electric initiator and igniters.Present widely used igniter is made up of ignition charge, igniter case, ignition lead, and principle is through initial firing current ignition charge to be lighted, and the flame that igniter produces ignites the main charge of guided missile rocket again.There are unstability factors such as mis-ignition in igniter, and main charge lights insufficiently, and initial combustion face is little, combustion speed is low, burning is not thorough.
Summary of the invention
The object of the present invention is to provide a kind of detachable igniter, solve that there is the unstability factor of mis-ignition in present igniter and the initial combustion face of main charge is little, low, the halfway problem of burning of combustion speed.
A kind of detachable igniter comprises: ignition charge also comprises: igniting primer, ignitron, igniter cartridge, insensitiveness igniter head.Insensitiveness igniter head is a column, and igniting primer is a pipe, and igniting primer one end places on insensitiveness igniter head, and the coaxial threaded connection, the axis of igniting primer and the axis normal of ignitron, and the other end end of igniting primer is connected with the sidewall thread of ignitron.Ignition charge places ignitron inner, and the direction perpendicular to axis on the ignitron outer surface has a plurality of flash holes.Main charge places in the igniter cartridge, and ignitron places the hole of igniter cartridge and closely contact.
During igniter work, initial firing current detonates the black powder in insensitiveness igniter head and ignites, and the flame of generation passes in the ignitron through igniting primer; Ignition charge in the ignitron is lighted; Ignition charge begins rapid burning from outer surface, and the flame that produces in the combustion process is emerged through the flash hole on the ignitron, and the igniter cartridge that flame will be enclosed within on the ignitron burns broken; The main charge that ignites is then accomplished lighting fully of main charge.
The present invention's igniting that realized detonating separates with main charge is lighted a fire; System's safety of ignition and stability have been strengthened through adopting insensitiveness igniter head; Use ignitron to realize the adequacy of main charge igniting simultaneously; Realize the combustion requirements of main charge, reduced the specification requirements such as mechanical property, combustion speed and combustion face of main charge, expanded application.

The specific embodiment
A kind of detachable igniter comprises: ignition charge 6 also comprises: igniting primer 2, ignitron 3, igniter cartridge 4, insensitiveness igniter head 1.Insensitiveness igniter head 1 is a column, and igniting primer 2 is a pipe, and igniting primer 2 one ends place on insensitiveness igniter head 1, and the coaxial threaded connection, the axis normal of the axis of igniting primer 2 and ignitron 3, and the other end of igniting primer 2 is connected with the sidewall thread of ignitron 3.Ignition charge 6 places ignitron 3 inside, and the direction perpendicular to axis on ignitron 3 outer surfaces has a plurality of flash holes 7.Main charge 5 places in the igniter cartridge 4, and ignitron 3 places the hole of igniter cartridge 4 and closely contact.
During igniter work, initial firing current detonates the black powder in insensitiveness igniter head 1 and ignites, and the flame of generation passes in the ignitron 3 through igniting primer 2; Ignition charge 6 in the ignitron 3 is lighted; Ignition charge 6 begins rapid burning from outer surface, and the flame that produces in the combustion process is emerged through the flash hole on the ignitron 37, and the igniter cartridge 4 that flame will be enclosed within on the ignitron 3 burns broken; The main charge 5 that ignites is then accomplished lighting fully of main charge 5.
