Abstract
The utility model discloses an igniter for an explosive driving shock wave tunnel, comprising an explosive segment tube body, an initiating wire and an initiating segment tube body. The initiating segment tube body is provided with a first end and a second end opposite to the first end, the first end of the initiating segment tube body is communicated with the explosive segment tube body, and the initiating wire is arranged at the second end of the initiating segment tube body. The igniter for the explosive driving shock wave tunnel of the utility model is adopted to detonate, the ignition energy generated by the igniter for the explosive driving shock wave tunnel is big enough, the ignition is safe, and the igniter for the explosive driving shock wave tunnel does not cause gas pollution.
Description
Technical field
The present invention relates to the wind-tunnel field, more particularly, relate to the apparatus to cause bursting that in the detonation driven shock tunnel, uses.
Background technology
Than general wind-tunnel, the detonation driven shock tunnel utilizes the high-temperature high-pressure fuel gas that produces after the inflammable gas detonation source of the gas as wind-tunnel.One of gordian technique in the detonation driven shock tunnel is that igniting formation is detonated immediately in burning mixture, and this requires the energy of igniting enough big.Existing apparatus to cause bursting is seen Fig. 1, comprises detonation section body 1, ignition silk 2, plug 3 and binding post 4, by apply high-tension current on binding post 4, by igniting 2 inflammable gas of directly igniting in this ignition detonation section body 1.Apparatus to cause bursting ignition energy shown in Figure 1 is limited, and the effect of detonating is bad.If big with the solid explosive ignition energy, but danger is high and cause air pollution, so generally will not adopt.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes igniting energy shortage in the existing blasting technology, provide a kind of can be safely, the apparatus to cause bursting of efficient ignition.
To achieve these goals, the apparatus to cause bursting that is used for the detonation driven shock tunnel that the utility model provides, comprise detonation section body, ignite silk and an ignition section body, this ignition section body have first end and with the first end second opposed end, described first end of igniting the section body is connected with detonation section body, and the described silk of igniting is installed in second end of igniting the section body.
Described second end of igniting the section body is equipped with plug, and plug is provided with and ignites the binding post that silk is connected.Described plug is tightly connected with second end of igniting the section body.Described first end of igniting the section body has the neck of a contraction, and this neck is connected with detonation section body.Described neck and detonation section body are tightly connected.
When adopting apparatus to cause bursting of the present utility model to ignite, the ignition energy of its generation is enough big, and the safety of detonating, and can not cause gas pollution.
Description of drawings
Fig. 1 is an apparatus to cause bursting structural representation of the prior art.
Fig. 2 is the structural representation of apparatus to cause bursting of the present utility model.
The drawing explanation:
Detonation section body 1 is ignited silk 2 plugs 3 binding posts 4

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 2 is an embodiment of apparatus to cause bursting of the present utility model, comprises detonation section body 1 and powder squib body 5.First end 6 of igniting section body 5 is connected with detonation section body 1, and first end 6 of igniting section body 5 has the neck 8 of a contraction, and this neck 8 is connected with detonation section body 1 thread seal, and is provided with a sealing ring (not shown) in its junction.Plug 3 is connected with powder squib body second end 7 thread seals, and is provided with a sealing ring (not shown) in its junction.Ignite silk 2 and be arranged in the ignition section body 5, and the binding post 4 outside passing through plug 3 and igniting section body 5 is connected.
In one embodiment, the internal diameter of detonation section body 1 is 150mm, and then the internal diameter of neck 8 can be chosen between 15mm-30mm, is preferably 20mm.Ignite the length of section body 5 and choose between 200mm-300mm, its internal diameter is chosen between 30mm-50mm, is preferably 45mm.
When adopting apparatus to cause bursting shown in Figure 2 to implement to ignite, in the process of inflation in detonation section body 1, inflammable gas charges into powder squib body 5 simultaneously.After inflation finished, plus high-pressure power supply on binding post 4 made ignition silk 2 heat the inflammable gas of lighting in the powder squib body 5.Inflammable gas after the ignition imports detonation section body 1 by the neck 8 of powder squib body 5 into the macro-energy input form, and the inflammable gas in the detonation section body 1 is ignited.Because inflammable gas formed superquick action near intake can make detonation section wall greatly.
Claims (5)
