Abstract
The invention relates to a cabin segment abut-joint sealing structure, and belongs to the field of aviation sealing structures. A cabin connecting frame and a rear cabin connecting frame are connected in a flange manner, a copper wire embedding groove is designed in the end face of a flange of the front cabin connecting frame, a copper wire is embedded in the copper wire embedding groove, and the position between flange connecting end faces of the front cabin connecting frame and the rear cabin connecting frame is coated with a high-temperature sealant. Through combined and matched use of the high-temperature sealant and the copper wire, the sealing function at the high pressure, the low temperature and the high temperature can be achieved.
Description
Technical field
The present invention relates to a kind of cabin section Butt sealing structure, belong to aerospace seal construction applications.
Background technology
Guided missile, for adapting to complex environment, meets the ability of round-the-clock operation, it is ensured that electronic equipment can normal operation, it is desirable to cabin section interface has watertightness and air-tightness.Traditional flange docking structure adopts embedding aviation rubber rope to carry out interface sealing, and aviation rubber rope uses temperature less than 120 DEG C, is not suitable for the hot environment more than more than 400 DEG C.
Summary of the invention
The present invention is in order to overcome drawbacks described above, it is therefore intended that provide a kind of cabin section Butt sealing structure, thus ensureing the sealing at high pressure, low temperature and hot conditions lower flange interface.
The present invention to achieve these goals, adopts the following technical scheme that
A kind of cabin section Butt sealing structure, front deck connects frame and rear deck connects frame and adopts form of flanges to connect；
Design copper wire embedded groove on the end face of flange that front deck connects frame, embeds copper wire in copper wire embedded groove, connects at front deck and is coated with high-temperature seal adhesive between the Flange joint end face of frame and rear deck connection frame.
The junction connecting frame and rear deck connection frame at front deck is attached fixing by bolt assembly.
Flange bolt is extended by axial tension, causes that connecting end surface gap increases, and during low temperature, fluid sealant increases with end clearance and occurs elastic deformation to achieve a butt joint face seal；During high temperature, bolt elastic modelling quantity reduces, seal failure is caused for preventing end clearance from increasing to fluid sealant unsticking, select to be embedded in copper wire at facing groove, the use temperature of copper is less than 900 DEG C, the diameter of copper wire raises with temperature and becomes big, is compensated the increment in both ends of the surface gap by the increment of brass wire diameter, it is achieved sealing function.
Advantages of the present invention: the present invention is used by the combination accessory of high-temperature seal adhesive and copper wire, it is achieved the sealing function under high pressure, low temperature and high temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing 1:
A kind of cabin section Butt sealing structure, front deck connects frame 1 and rear deck connects frame 5 and adopts form of flanges to connect；
Design copper wire embedded groove on the end face of flange that front deck connects frame 1, embeds copper wire 2 in copper wire embedded groove, connects at front deck and is coated with high-temperature seal adhesive 4 between the Flange joint end face of frame 1 and rear deck connection frame 5.
The junction connecting frame 1 and rear deck connection frame 5 at front deck is attached fixing by bolt assembly 3.
Front deck connects frame 1 and rear deck connects frame 5 and adopts form of flanges to connect, and selects bolt assembly 3 according to connecting load, calculates bolt axial maximal tensility during low temperature, design high-temperature seal adhesive 4 thickness, it is ensured that it is the unsticking because end clearance increases not, it is achieved cabin section seals；Calculate bolt shaft axial maximal tensility during high temperature, design copper wire 2 radial dimension, and connect design copper wire embedded groove on frame at front deck, temperature increases makes the diameter of bolt increase, the gap that both ends of the surface produce is compensated because of bolt elongate, it is achieved cabin section seals by the increment of brass wire diameter.Combination by high-temperature seal adhesive and copper wire, it is achieved the sealing function under cabin section interface low temperature and high temperature.
High-temperature seal adhesive is: HM310 sealant.
