Abstract

The utility model relates to a novelty stab delay detonator and is characterized in that the detonator adopts a design of composite structure and axial compound decaying gasket; moreover, the utility model has the features that the stab sensitivity is high, the delay time precision is high and the output energy is primarily radial. In a fuse basic type mechanism revolving body and the detonator is in isolated state, the stab delay detonator will not detonate other explosive devices in the same mechanism revolving body and will not damage the axial component of revolving body; when the detonator is in operating mode, the stab delay detonator should implement stab ignition reliably and delay accurately, and the output effect should sympathetically detonate an instant detonator which plays detonation transmission below the radial direction of the same revolving body.

Description

A kind of novel stab delay detonator

The utility model is a kind of novel stab delay detonator, and its technical field relates to firework theory.

At present, the stab delay detonator that domestic and international fuse is used, generally be between prickling power and delay powder powder charge interface, to adorn a metal or nonmetallic isolated attenuation pad, be used for reducing the impact of prickling power to the delay powder burning, overcome the influence of energy position level gradient difference, reach the purpose that improves the acupuncture defer time, attenuation pad promptly will effectively be controlled the output energy of prickling power, reliable ignition delay powder again, the design technology difficulty is big, is easy to generate half quick-fried or induced detonation, and is also undesirable to improving the delay precision effect, the product assembling is difficulty also, difficult quality guarantee.Tie employing prickling power → delay powder → priming → high explosive in powder charge, this structure explosive payload is bigger, can't satisfy stab delay detonator miniaturization day by day, requirement that the powder charge volume is more and more littler, the product course of reaction can not normally be carried out, bring adverse influence through properties of product, the output action of stab delay detonator structure also is based on axial output action, easily causes the destruction of the detonation shock wave of main charge (high explosive) to axial members.

The purpose of this utility model is a kind of novel stab delay detonator of development.

Technology of the present utility model is situated between certainly, and scheme is: a kind of novel stab delay detonator, by capsule, compound attenuation pad, priming, acupuncture delays to manage formation, acupuncture delays to assemble the acupuncture delay powder in the pipe, delay powder, charge constitution adopts acupuncture delay powder → delay powder → priming, priming dextrin lead azide is a main charge, at compound attenuation pad of blaster cap outlet end bottom assembling by metal attenuation pad and the combination of nonmetal attenuation pad, the metal attenuation pad is made of aluminium, nonmetal attenuation pad is made of paper wood, the stab delay detonator assembling is the compound attenuation pad of packing in the blaster cap outlet end bottom in regular turn, the priming of packing into then, again stab delay detonator is pressed in the capsule, again capsule is closed up.

Advantage of the present utility model and good effect, has acupuncture delay precision height, technology is simple, constant product quality, main charge do not have high explosive, output action is reliable, suitable, axially output action is little, fuse fundamental mode movement revolving body is not destroyed, and radially output action is reliable, can ignite instantaneous cap in the same revolving body reliably.

Accompanying drawing: a kind of novel stab delay detonator structure principle chart.

Accompanying drawing is described a kind of novel stab delay detonator structural principle in detail, the compound attenuation pad 2 of successively packing into and making of aluminium and paper wood in capsule 1 output bottom, the priming 3 of packing in regular turn again, the dextrin lead azide, being pressed into acupuncture delays to manage 4, then capsule 1 is closed up, acupuncture delays to manage pack into successively in 4 acupuncture delay powder 6, delay powder 5.
