Abstract
The utility model discloses a double-membrane decompressor which includes a U-shaped launcher; at least one inlet membrane is arranged at the inlet of the U-shaped launcher; and at least a water holding membrane is arranged at the bottom part of the U-shaped launcher. The utility model adopts the technical scheme, skillfully employs the double-membrane structure arranged on the U-shaped launcher, meets the sealing requirement when launching a guided missile at a water depth being 0-60 m, satisfies the demand of pressure-equalizing balance of the launcher and the seawater, ensures the water sealing requirement inside a cooler and the air sealing requirement of 0.7 MPa pressure inside the launcher, solves the key technical problem with large depth and variable depth guided missile launching, can be directly applied to various submarine-based guided missile launchers and testing systems thereof, and offers the advantageous conditions to develop the submarine-based guided missile launching technology.
Description
Technical field
The utility model relates to a kind of decompressor, and specifically a kind of being applied in the submarine launched missile Vertical Launch field can make the two film decompressors that all flatten weighing apparatus inside and outside the launching tube.
Background technology
The competition of current science and techniques of defence is growing more intense.In the prior art, PET bill of materials membrane structure only can pressure-bearing 0.4MPa pressure airtight, and bearing capacity double-deck, multi-layer film structure is not directly proportional with its number of plies, and can influence the fluid passage of launch power system, so submarine launched missile Vertical Launch dynamical system internal membrane intensity can only satisfy under water 30m with interior launch requirements, and can not adapt to the sealing and the requirement of strength of darker Underwater Launched Missile, great inhibition has been played in this development to the submarine-based missile lift-off technology.
Summary of the invention
The purpose of this utility model provides a kind of being applied in the submarine launched missile Vertical Launch field, can make the two film decompressors that all flatten weighing apparatus inside and outside the launching tube, isolate launch power system and cooler watertight.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises U type launching tube, is provided with at least one in the porch of U type launching tube and goes into diaphragma of mouth, is provided with at least one dash film in the bottom of U type launching tube.
Be provided with one in the porch of U type launching tube and go into diaphragma of mouth, be provided with a dash film in the bottom of U type launching tube.
Be provided with one in the porch of U type launching tube and go into diaphragma of mouth, be provided with two dash films in the bottom of U type launching tube.
Above-mentioned go into diaphragma of mouth and the dash film is the film body that adopts modification polyester materials PET.
Adopt the utility model of technique scheme, utilize the two membrane structures that are arranged on U type launching tube dexterously, solved the seal request when 0～60m depth of water is launched a guided missile, satisfied the requirement that launching tube and seawater all flatten weighing apparatus, guarantee the interior watertight requirement of airtight and cooler of 0.7MPa pressure in the launching tube, solved a big degree of depth degree of the deepening key technology of launching a guided missile, can directly be applied in various submarine-based missile emitters and the pilot system thereof, for the development of submarine-based missile lift-off technology provides advantage.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises U type launching tube 3: be provided with into diaphragma of mouth 1 in the porch of U type launching tube 3, bottom at U type launching tube 3 is provided with dash film 2, like this, go into diaphragma of mouth 1 and dash film 2 and just formed two film pressure reduction structures, and go into diaphragma of mouth 1 and dash film 2 and be the film body that adopts modification polyester materials PET.
PET bill of materials membrane structure only can pressure-bearing 0.4MPa pressure airtight, launch power system entry barrier film is by the dash film inner with it 2 ingenious pair film pressure reduction structures that are designed to, make its bearing capacity improve two times, reach 0.8MPa pressure, be equivalent to the 60m water depth pressure.The utility model is exactly design one space between two films, and this space is according to the design of the distortion of film and pressure-bearing, and launch power system entry barrier film 1 is to guarantee the airtight of 0.7MPa pressure in the launching tube by two film pressure reduction structures.When all pressing in the launching tube 3, go into diaphragma of mouth 1 moderate finite deformation takes place, 2 distortion of dash film are less, space internal pressure between two films is raise, the pressure that each diaphragm bears within its ability, plays the effect of decompression again, satisfies the equal pressure request of 0～60m depth of water, guarantee that cylinder pressure can not have influence on dash film 2 higher levels' launch power system, thereby realized the sealing and the requirement of strength of 0～60m depth of water MISSILE LAUNCHING.
It is to be noted in addition, the utility model can also be set to the multimembrane structure as required, can be provided with two, three even more go into diaphragma of mouth in the porch of U type launching tube 3, be provided with two, three even more dash film in the bottom of U type launching tube 3, only need guarantee that leaving certain space between per two barrier films gets final product, the multimembrane structure can realize decompression better.
