Description
Technical field
The present invention relates to a kind of delay detonator, more particularly to a kind of extension duration can be reached 10 seconds and the overlength of the above is delayed
Detonator.
Background technology
Delay detonator is measured with the delay powder control delay second both at home and abroad at present, mostly within 10 seconds, is delayed more than 10 seconds
It yet there are no document announcement.Its reason mainly has two aspects:One the problem of be delay powder itself, and transmission speed is slow, and energy is small, combustion
Burning, which was delivered to after certain time, cannot continue to transmit and cutoff, and flame is just passed to go down, and what is generally said is exactly misfire, is not reached
The purpose of detonating capsule;Two be that delay precision is not high, difficult control time, does not reach predetermined requirement, influences engineering explosion effect.
The content of the invention
The invention aims to overcome defect present in prior art, there is provided a kind of extension time length, precision are high
Overlength delay detonator.
To realize object above, the present invention is adopted the following technical scheme that:A kind of overlength delay detonator, including primer casing,
High explosive powder charge, initiating unit are sequentially arranged with the primer casing from left to right, long delay element, igniter, bayonet socket plug, is drawn
Payment to a porter;The long delay element includes long extension body case, and the long extension body case is sequentially arranged with lead delay element, the from left to right
One tungsten series delay powder, the serial delay powder of the second tungsten, ignition charge;The high explosive powder charge is high explosive first successively from left to right
Secondary powder charge, second of powder charge of high explosive.
Further, the serial delay powder composition proportion of first tungsten is:Tungsten powder 30%;Barium chromate 56%;Potassium hyperchlorate 9%;
Diatomite 5%.
Further, the serial delay powder composition proportion of second tungsten is:Tungsten powder 26%;Barium chromate 60%;Potassium hyperchlorate 9%;
Diatomite 5%.
Further, the initiating unit is priming DDNP or detonation element.
Further, the igniter is detonator or electric igniter.
Further, particle hexogen is selected in second of powder charge of high explosive, and high explosive first time powder charge is from compacting
Hexogen.
Preferably, the composition of the ignition charge is brown lead oxide.
Preferably, the composition of the ignition charge is:Silica flour and lead orthoplumbate are with 8:2 proportionings.
Preferably, the composition of the ignition charge is:Silica flour and lead orthoplumbate are with 5:3 proportionings.
Preferably, the composition of the ignition charge is:Silica flour and lead orthoplumbate are with 6:2 proportionings.
The present invention first fills that burn rate is fast, the delay powder that flame intensity is big, energy is big using the charging means of clearance-type, then
Refill the delay powder that burn rate is slow, energy is small.Energy gradient and flame transmission gradient are alternately formed, when being allowed to increase extension
Between.After expected delay is reached, and high speed medicine is loaded on from low speed medicine, the detonation for making it there are enough energy to remove percussion detonator.
The present invention has following good effect compared with prior art:(1)The extension time is long, and reliability is high, will not produce blind
Fiery phenomenon;(2)Delay precision is high, can be precisely controlled the detonator delay time;(3)Manufacture craft is simple, easily installs;(4)Safety
Property high, not accident-proneness;(5)Production technology and equipments are identical with general delay detonator, are easy to implement industrialization.
The present invention has that extension is long, reliability is high, delay precision is high, technique is simple, it is safe the characteristics of.
