Abstract
Primacord excitor of the present invention, comprises fixing part and subchassis, and one end of described fixing part is provided with internal thread, and the other end of fixing part is provided with fixed orifices, by a cavity connects between described fixed orifices and described internal thread; Described subchassis is the right cylinder that there is through hole in an axle center, and subchassis arranged outside has the outside screw corresponding with described internal thread, the through hole of described subchassis and described cavity connects.Primacord excitor of the present invention utilizes shockwave principle, is placed on by electric igniting assembly in a closed cavity, by igniting electric igniting assembly, produces high temperature impact ripple in the cavities, thus ignites primacord, band crash of thunder pipe.The present invention is easy to realize, and can reuse, thus can reduce blasting cost.
Description
Technical field
The invention belongs to explosion field, be specifically related to a kind of primacord excitor.
Background technology
Primacord, also known as nonel tube.For inwall scribbles the plastic hose of pyrotechnic composition powder (explosive and powder mixture).Be made up of the high-pressure polyethylene material of internal diameter 1.5 millimeters, external diameter 3 millimeter, pyrotechnic composition proportioning is hexogen 91%, and aluminium powder and other compositions 9%(common discolor nonel primer proportioning are RDX75%:Al25%), coating dose 14 ~ 16 milligrams/meter.Can by various detonator, primacord fuse, percussion rifle, specially excite the initiation such as rifle and fire element.Form a kind of special detonation in pipe after causing, its detonation wave is propagated with constant speed.It can only detonating primer and can not fired charge, and propagation performance is good, meets fire burning and is not excited, strong shock resistance, and water resistant and resistance to voltage are all good, and tool some strength, cost is low, generally uses.
At present, primacord is excited and mainly adopts electric arc or shockwave two kinds of modes.Arc excitation method, under high pressure positive and negative electrode sparks, and often can cause two most advanced and sophisticated oxidations, the metallic residue that the chemical reaction occurred in exciting produces sticks to electrode surface, causes the difficulty in reusing; Adopt shock-wave excitation, existing Multifunctional electric detonator or the rear shockwave produced of primacord fuse blast, excite primacord, causes cost in explosion to increase.
Summary of the invention
The object of this invention is to provide one to be easy to realize, can reuse, and the primacord excitor that blasting cost is cheap.
Primacord excitor of the present invention, comprises fixing part and subchassis, and one end of described fixing part is provided with internal thread, and the other end of fixing part is provided with fixed orifices, by a cavity connects between described fixed orifices and described internal thread; Described subchassis is the right cylinder that there is through hole in an axle center, and subchassis arranged outside has the outside screw corresponding with described internal thread, the through hole of described subchassis and described cavity connects.
As optimization, described fixed orifices is a tapered hole, and outside it, aperture is less than medial aperture.Outside it, aperture is less than the diameter of fire element slightly, fire element can be fixed on fixed orifices by its molded portion by fire element.
Described subchassis is provided with cyclic lug in the through hole of one end of described cavity.Guarantee that primacord can not pass subchassis, can prevent primacord from being inserted by the medicine head of fire element broken.
Near the internal thread of described fixing part and described cavity junction, stop bosses is set.When can guarantee that subchassis is screwed into fixing part, the medicine head of fire element can not be touched.Primacord excitor can adopt steel material to make.
During use, primacord is inserted in the through hole of subchassis, be fixed on by fire element on fixing part, be screwed in the internal thread of fixing part by subchassis by its outside screw, subchassis keeps certain distance between the medicine head of one end of fixing part with fire element.Excited the medicine head of fire element by detonating power supply, the burning of medicine head produces high temperature impact ripple, primacord can be excited.
Primacord excitor of the present invention utilizes shockwave principle, is placed on by electric igniting assembly in a closed cavity, by igniting electric igniting assembly, produces high temperature impact ripple in the cavities, thus ignites primacord, band crash of thunder pipe.The present invention is easy to realize, and can reuse, thus can reduce blasting cost.
Accompanying drawing explanation
Fig. 1 is primacord excitor structural representation of the present invention.
Fig. 2 is the use schematic diagram of primacord excitor of the present invention.
Embodiment
Primacord excitor, as shown in Figure 1 and Figure 2, comprise fixing part 2 and subchassis 1, one end of fixing part 2 is provided with internal thread 4, and the other end of fixing part 2 is provided with fixed orifices 5, is communicated with between fixed orifices 5 and internal thread 4 by a cavity 6; Subchassis 1 is the right cylinder that there is through hole in an axle center, and subchassis 1 arranged outside has the outside screw 3 corresponding with described internal thread 4, and the through hole of subchassis 1 is communicated with cavity 6.
Fixed orifices 5 is a tapered hole, and outside it, aperture is less than medial aperture.Outside it, aperture is less than the diameter of fire element 8 slightly, fire element 8 can be fixed on fixed orifices 5 by its molded portion by fire element 8.
Subchassis 1 is provided with cyclic lug 9 in the through hole of one end of cavity 6.Guarantee that primacord 7 can not pass subchassis 1, can prevent primacord 7 from being inserted by the medicine head of fire element 8 broken.
Near the internal thread 4 of fixing part 2 and cavity 6 junction, stop bosses 10 is set.When can guarantee that subchassis 1 is screwed into fixing part 2, the medicine head of fire element 8 can not be touched.
During use, primacord 7 is inserted in the through hole of subchassis 1, fire element 8 is fixed on fixing part 2, be screwed in the internal thread 4 of fixing part 2 by subchassis 1 by its outside screw 3, subchassis 1 keeps certain distance between the medicine head of one end of fixing part 2 with fire element 8.Excited the medicine head of fire element 8 by detonating power supply, the burning of medicine head produces high temperature impact ripple, primacord 7 can be excited.Primacord excitor can adopt steel material to make.
Primacord excitor of the present invention utilizes shockwave principle, is placed on by electric igniting assembly in a closed cavity, by igniting electric igniting assembly, produces high temperature impact ripple in cavity, thus ignites primacord, and band is thundering and manages.The present invention is easy to realize, and can reuse, thus can reduce blasting cost.
