Abstract
The utility model belongs to expansion pipe separation device, in particular discloses a continuous separation device for transversely separating expansion pipe, which comprises a flat pipe with gap; the flat pipe is mounted in an annular hollow cavity formed by an upper shell body, a lower shell body, an outer separation plate and an inner separation plate; filling material is arranged in the flat pipe; an explosive cord is arranged in the center of the filling material; wherein, the gap of the flat pipe is connected with a butt joint flat pipe in sealing mode; a gap is formed on the inner side of the butt joint flat pipe; two detonators are arranged on the gap; each detonator is connected with one end of the explosive cord. The continuous separation device for transversely separating expansion pipe has simple structure, not only can satisfy the sealing requirement of aviation vehicle, but also can realize continuous bearing.
Description
Technical field
The utility model belongs to a kind of Expansion Tube Separating Device, is specifically related to a kind of lateral separation bulged tube continuous separation device that is used for space launch vehicle.
Background technology
Expansion Tube Separating Device as shown in Figure 1 is used for the lateral separation of space launch vehicle, has the low free of contamination characteristics of impacting.Its principle of work is: linear-shaped charge 2 is detonated instantaneous pressure that the back produces and impact and flat tube 1 is expanded to both sides outer separating plate 4 and interior separating plate 8 are expanded along indentation, there break, thereby the upper shell 6 of the space launch vehicle that links together and lower house 7 are separated, realize the lateral separation function of space launch vehicle.In original Expansion Tube Separating Device, have breach 10 as described in Figure 2 on the flat tube 1, be provided with firing device 9 fired charge ropes 2 in this breach, thereby provide energy for the lateral separation of space launch vehicle.This breach causes the carrying of Expansion Tube Separating Device discontinuous, also can't satisfy the requirement of space launch vehicle leak free simultaneously.Space launch vehicle is to prevent entering of air-flow and other object in flight course, must increase sealing arrangement in addition, discontinuous by flat tube 1 formed Expansion Tube Separating Device carrying simultaneously, both sides at the breach of flat tube 1 also need to increase auxiliary carrying measure, the complexity of taking to have increased the space launch vehicle system architecture of above measure.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, can either satisfy the requirement of space launch vehicle leak free, can carry continuous lateral separation bulged tube continuous separation device again.
Realize the technical scheme of the utility model purpose: a kind of lateral separation bulged tube continuous separation device, it comprises the flat tube that has breach that is installed in the toroidal cavity that is formed by upper shell, lower house, outer separating plate and interior separating plate, be provided with weighting material in the flat tube, the weighting material center is provided with linear-shaped charge, wherein, the indentation, there of described flat tube is sealedly connected with the butt joint flat tube, butt joint flat tube inboard has breach, this indentation, there is provided with two firing devices, and each firing device is connected with an end of linear-shaped charge.
Useful technique effect of the present utility model is: the utility model adopts the butt joint flat tube that the two ends of former flat tube are connected into an integral body, can either satisfy the requirement of space launch vehicle leak free, can carry again continuously, thus reduce space launch vehicle system architecture complexity be used for lateral separation bulged tube continuous separation device.

The specific embodiment
Below in conjunction with drawings and Examples a kind of lateral separation bulged tube continuous separation device provided by the utility model is described in further detail.
A kind of lateral separation bulged tube continuous separation device, it comprises the flat tube that has breach 1 that is installed in the toroidal cavity that is formed by upper shell 6, lower house 7, outer separating plate 4 and interior separating plate 8, be provided with weighting material 3 in the flat tube 1, weighting material 3 centers are provided with linear-shaped charge 2, wherein, the indentation, there of flat tube 1 is sealedly connected with butt joint flat tube 5, and butt joint flat tube 5 inboards have breach, this indentation, there is provided with two firing devices 9, and each firing device 9 is connected with an end of linear-shaped charge 2.
The upper shell 6 of space launch vehicle, lower house 7 are by outer separating plate 4 and interior separating plate 8 captive joints.Outer separating plate 4 is enclosed within upper shell 6 and lower house 7 outsides, and interior separating plate 8 is enclosed within upper shell 6 and lower house 7 inside, is bolted to connection between outer separating plate 4, upper shell 6 and the interior separating plate 8.Be bolted to connection between outer separating plate 4, lower house 7 and the interior separating plate 8.Upper shell 6, lower house 7, outer separating plate 4 and interior separating plate 8 form toroidal cavity.
When needs with upper shell 6, lower house 7 separately the time, by firing device 9 explosive blasting ropes 2, linear-shaped charge 2 is detonated instantaneous pressure that the back produces and impact and flat tube 1 is expanded to both sides outer separating plate 4 and interior separating plate 8 are expanded along indentation, there break, thereby the upper shell 6 of the space launch vehicle that links together and lower house 7 are separated, realize the lateral separation function of space launch vehicle.
