Abstract
The utility model relates to a civilian solid rocket motor nozzle sealing device, which belongs to the technical field of missiles and rockets. The civilian solid rocket motor nozzle sealing device comprises a sealing cover, a gland and a sealing adjusting gasket. The gland is inserted in an annular locking groove on a mouth portion of the sealing cover through a positioning block of a cylindrical locking stand of the gland, the gland is rotated to be locked with the sealing cover axially, and one end of a plug of an electric connector is compacted in a cylindrical groove of the gland by the sealing adjusting gasket. By using the civilian solid rocket motor nozzle sealing device, the operation response time can be effectively shortened, the operation efficiency of hail suppression and rain enhancement is improved, the equipment consumption is reduced, and the economy of products is increased.
Description
Technical field
The utility model relates to a kind of civilian solid rocket motor nozzle sealing device, belongs to play the arrow technical field.
Background technology
The ignition loop of present civilian hail-proof rain-increasing rocket is essential twice electrical connector plug of completion continuously and socket connecting moves when emission; Ignition loop like domestic certain type hail-proof rain-increasing rocket; As shown in Figure 1; Electric connector socket 4 is fixed on the engine jet pipe sealing blanking cover 3 through fastening screw 1 and sealing ring 2, when rocket projectile launch, must use two respectively to have the plug-assembly of an electrical connector plug, and socket is connected on plug of first completion and the launcher; After accomplishing being connected of socket on other end plug and the rocket projectile motor jet pipe sealing blanking cover again, just can launch.Operant response time when this technical scheme has not only increased emission, reduced the hail-proof rain-increasing operating efficiency; And rocket projectile of every emission will consume electric connector socket and two electrical connector plugs on the plug-assembly on the rocket projectile, increase launching costs.In addition, electric connector socket 4 and the fixed structure that seals blanking cover 3 are unfavorable for the detection to internal structure, and required function is changed electric connector socket 4.
The utility model content
The purpose of the utility model is ignition loop essential twice electrical connector plug of completion continuously and socket connecting moves when emission that will solve traditional hail-proof rain-increasing rocket; Increase the operant response time; And, the problem that rocket projectile of every emission will consume an electric connector socket and two electrical connector plugs.And a kind of civilian solid rocket motor nozzle sealing device is provided
The purpose of the utility model realizes through technical scheme:
A kind of civilian solid rocket motor nozzle sealing device of the utility model comprises sealing blanking cover, gland and sealing adjusting pad.
Sealing blanking cover center is processed with a cylindrical shape plug positioning table; The inwall of plug positioning table inwardly is processed with plural stopper slot from oral area; The oral area of sealing blanking cover is processed with annular screens groove, and the annular screens groove of sealing blanking cover oral area is outward extended with plural gathering sill.The plug opposite end outer wall of electrical connector plug is processed with the locating piece that the stopper slot with the plug positioning table is complementary, and the plug opposite end of electrical connector plug inserts in the stopper slot of plug positioning table.Be processed with a cylinder shape groove and a cylindrical shape screens platform on the side plate face of gland, cylindrical shape screens platform is processed with and seals the locating piece that the annular screens groove of blanking cover oral area is complementary at outer wall.Gland inserts in the annular screens groove of sealing blanking cover oral area through the locating piece of its cylindrical shape screens platform, rotates gland and makes itself and the axial screens of sealing blanking cover, seals plug one end that adjusting pad compresses electrical connector plug through placing in the cylinder shape groove of gland.
Beneficial effect:
Adopt the engine jet pipe sealing device of the utility model; Fixed electric connector socket on the former technical scheme rocket projectile is transformed to has required function and electrical connector plug that can convenient taking-up when emission is used; And being connected with electric connector socket on its disposable completion and the big gun; Can effectively shorten the operant response time on the one hand, improve the hail-proof rain-increasing operating efficiency; Can also reduce equipment consumption on the other hand, increase the economy of product.
