Description

A kind of two-way non-priming ring energy output detonator
Technical field
The invention belongs to explosive technical field, and in particular to a kind of double end non-priming ring energy exports detonator.
Background technology
Highway excavate, tunnelling, earthwork explosion, resource exploitation, Urban Blasting concerning the national matter of fundamental importance heavy construction all The use of explosive is be unable to do without, while also be unable to do without the dependence to explosive, it can thus be appreciated that China is to explosive demand pole Greatly, the usage amount of particularly detonator is very big, and these detonators are a considerable wealth, if it is possible to reduce the use of detonator Amount, can necessarily save the no small expense of next record.
In a practical situation, due to detonator be likely to occur it is half quick-fried or miss-fire, so industrially can in order to improve blasthole By property, even multiple detonator often is sent out in same parallel hole connection two, to reduce the probability of miso-fire, although can so improve system System reliability, but the usage amount of detonator is increased one times fully, herein for such case, devising one kind can be double Detonator is exported to the ring energy of input, one end that it changes traditional detonator inputs one end output and mainly utilizes axial energy The characteristics of output, with reference to Mohaupt effect, radially output energy is improved, can reach while be inputted from both ends, radially the spy of output Point.This novel double-end ring exports detonator, can detonate from both ends, while output of detonator energy is not reduced, carry simultaneously The high reliability of total system, the half usage amount of the detonator of reduction.
Currently, someone did double end flame detonator, and on the one hand it uses flame priming mode of excitation, and security is too poor, Easily there is accident, and it is only that the energy for leaning on high explosive is used as output energy, and its power will necessarily compared with conventional detonator Substantially reduce, and the double end detonator designed by the present invention is on the one hand reliable using non-priming film flying technical security, on the other hand Bigger with reference to the output of ring energy-gathering jetting principle energy, initiating ability is stronger.
The content of the invention
It is an object of the invention to：There is provided it is a kind of can industrially reliable initiation two directions' inputing ring energy output Detonator without burster, it can realize the reliability that single-shot detonator is improved from two directions' inputing excitation energy, while ingenious utilization Ring Mohaupt effect, ring (radial direction) output energy is improved, has capacity usage ratio high, taken and consume that small, security performance is superior, reliably The features such as property is high.
The present invention is realized by following technical scheme：
A kind of two-way non-priming ring energy output detonator, including the metal tube with ring troughs for collecting energy both ends open Shell, two energy input passages being seated in successively in Can, two excite part and two main body powder charge parts；Two Individual energy input passage can be detonator, rubber stopper either primacord or electric charge input payment to a porter；Overall structure is along pipe Middle full symmetric filling, energy are inputted from the signal input channel at both ends, when signal input channel is detonator, led quick-fried simultaneously Pipe is connected under external force extruding together by using hollow rubber plug and tube wall, both ends detonator input time break, right Claim to excite two symmetrical excitation apparatus immediately following detonator rear, excitation apparatus is that non-priming film flying excites interior cap device, is swashed Transmitting apparatus produces the main charge that symmetrically detonates immediately after again of High Speed Flyer, and main charge crushes cumulative ring shaped slot, produces cumulative and penetrates Ring is flowed, blast hole projectile filling is finally ignited, completes whole initiation process.
Wherein, energy input part, electricity input or non-electricity output can be made.It is defeated that non-electrical input can be divided into detonator again Enter or primacord input, can by closing-up machine extrude be fixed in Can, while can also determine as needed be It is no to use delay element, line delay element can be used to reach the purpose of design of delay detonator.Part is excited to use non-priming film flying Mode of excitation.By exciting medicine and metal inner cap to form, exciting medicine, it has a large amount of high temperature and high pressure gas of releasing that can burn rapidly Characteristic, here with KCLO3With RDX mixing (1:1) exemplified by, thin wall cylinder-shaped that interior cap is made of metal, bottom processes presplitting Indentation, film flying is formed along pre-scoring under gases at high pressure promotion.
Wherein, main body powder charge part can be divided into booster explosive and the two-part multiple charge structure of donor charge, present ether Exemplified by peace, booster explosive is that to be respectively that the first order is in bulk pacify very much two-stage charge constitution, and the second level is about 1.2g/cm for press fitting density3 Pacify very much, donor charge for compacting too peace (density takes 1.7g/cm3) or RDX.
Wherein, the centre position of the metal circular tube of both ends open nearby sets an appropriate number of annular for having and being parallel to each other Groove, the groove shape can make taper or semicircle, referred to as energy-gathering ring, and width of the groove on housing periphery is metal tube The 1/4-1/5 of shell diameter, the drift angle of tapered cross-section is 60 ° -120 °, and the spacing of the axis of adjacent two endless groove is well width 2~5 times.It is structurally characterized in that in order that explosive energy, which is concentrated, acts on ring, produces high pressure, high speed, high temperature and highdensity Jet, to improve the output of the energy of ring.
Wherein, its detonator can be simultaneously from both ends input energy, and utilizes energy-gathering jetting principle, strengthens the lateral of energy Output, while can decide whether to reach delayed effect using delay element as needed.
Operation principle of the present invention is：When energy simultaneously from the input of the energy input devices at shell both ends (as needed whether Need an extension body), then light in interior cap and excite medicine, excite medicine rapid COMBUSTION TO DETONATION TRANSITION in confined space, produce a large amount of Gases at high pressure, cap in shearing, it is set along bottom to be intended to crackle and produce booster explosive of the High Speed Flyer simultaneously into main charge to hit, so The Impact Initiation first order is in bulk afterwards pacifies very much, will have enough energy excitation second level press fitting booster explosives after too peace detonation in bulk, now Re-detonate the main charge being compacted, and can crush a lot of energy-gathering ring in the process, produces a plurality of high speed along radially (ring) High temp jet, blast hole projectile filling around Impact Initiation, reach the purpose of reliable initiation blasthole.
The present invention compared with prior art the advantages of be：The double end non-priming ring cumulative output detonator of the present invention, The equal reliability of two hairs old-fashioned detonator in parallel can be reached by using single-shot detonator, do not reducing the same of output of detonator energy When, the detonator usage amount of half is reduced, improves blasthole reliability, saves a large sum of expense, and ring cumulative principle is combined, increase Strong lateral fan-out capability, improve the reliability of blasting cap initiation.
