Abstract
The utility model provides a combined-type sealing ring, which relates to a sealing ring and solves the problems as follows: the prior missile launch container adopts an O-shaped sealing ring for sealing; and when a missile is launched, the O-shaped sealing ring is hung on the missile and the missile can not be normally launched. The axial section of the utility model consists of a Y-shaped rubberelastic body (1) and an inverted T-shaped rubber elastic body (2), the Y-shaped rubber elastic body (1) is arranged above the inverted T-shaped rubber elastic body (2), and the Y-shaped rubber elastic body and the inverted T-shaped rubber elastic body are molded wholly. Since the axial section is formed by the combination of the Y-shaped rubber elastic body (1) and the inverted-T shaped rubber elastic body and shaped in a manner that the inverted T-shaped rubber elastic body is embedded in an inverted-T shaped groove matched with the inverted T-shaped rubber elastic body, so that the combined-type rubber sealing ring can possess the self-locking function; and when the missiles are lunched, the combined-type sealing ring is firmly fixed on a metal end frame and does not fall, so that the missiles can be launched smoothly.
Description
Technical field
The utility model relates to a kind of seal ring.
Background technique
Existing MISSILE LAUNCHING case sealing is to adopt O type rubber seal to seal, because the inside and outside pressure reduction of firing box is about 0.017Mpa, during MISSILE LAUNCHING, case lid is opened by explosive power earlier, in the moment of opening case lid, O type rubber seal just comes off automatically and hangs on the guided missile, has influenced the emission of guided missile, therefore, O type rubber seal can not satisfy the sealability of firing box.
The model utility content
The purpose of this utility model is to adopt O type rubber seal for solving existing MISSILE LAUNCHING case sealing, and during MISSILE LAUNCHING, O type rubber seal is easy to hang on guided missile, causes the problem that guided missile can not normal transmission, and a kind of combined type packing ring is provided.
Axial cross section of the present utility model is made up of Y shape rubber elastomer and inverted T-shaped rubber elastomer, and Y shape rubber elastomer is positioned at the top of inverted T-shaped rubber elastomer, and the two makes one.
The utility model has the advantages that: one, because the utility model is to be that Y shape rubber elastomer and inverted T-shaped rubber elastomer combine by axial cross section, axial cross section is embedded in the inverted T-slot that cooperates with it for the inverted T-shaped rubber elastomer, make the combined type rubber seal have auto-lock function, during MISSILE LAUNCHING, combined type packing ring firmly is fixed on the metal end frame, do not come off, make guided missile launch smoothly.Two, the utlity model has two way sealed performance and selfsealings performance, can satisfy the seal request of MISSILE LAUNCHING case, make the MISSILE LAUNCHING case of inside and outside pressure reduction in 0～0.017Mpa scope all can keep excellent sealing performance.Three, the utility model is suitable for having the sealing that planes are docked in two of gap.
Description of drawings
Fig. 1 is the main sectional view of the utility model combined type packing ring, and Fig. 2 is that combined type packing ring is installed in metal frame 3-1 on the MISSILE LAUNCHING case 3 and the user mode figure between the case lid 3-2 interface, and Fig. 3 is the I partial enlarged drawing of Fig. 2.
Embodiment
Embodiment one: in conjunction with Fig. 1 present embodiment is described, the axial cross section of present embodiment is made up of Y shape rubber elastomer 1 and inverted T-shaped rubber elastomer 2, and Y shape rubber elastomer 1 is positioned at the top of inverted T-shaped rubber elastomer 2, and the two makes one.Axial cross section is that Y shape rubber elastomer 1 and inverted T-shaped rubber elastomer 2 all have certain elastic compression amount.During use, metal frame 3-1 on the MISSILE LAUNCHING case 3 is provided with the T-slot 3-1-1 that cooperates with inverted T-shaped rubber elastomer 2 with case lid 3-2 interface, with axial cross section is that the T end of inverted T-shaped rubber elastomer 2 is embedded in the T-slot 3-1-1, when MISSILE LAUNCHING, inverted T-shaped rubber elastomer 2 is locked on the metal frame, prevented that seal ring from hanging on the guided missile, therefore, inverted T-shaped rubber elastomer 2 has played the effect of self-locking.
Embodiment two: in conjunction with Fig. 1 present embodiment is described, the axial cross section of present embodiment is that the elastic compression amount of Y shape rubber elastomer 1 is no more than 1.5mm.Because case lid 3-2 on the MISSILE LAUNCHING case 3 and the gap between the metal frame 3-1 interface are no more than 1.5mm, therefore, Y shape rubber elastomer 1 is arranged between case lid 3-2 and the metal frame 3-1 interface just can play seal action, sees Fig. 2 and Fig. 3.Other composition and annexation are identical with embodiment one.
Working principle of the present utility model: referring to Fig. 2 and Fig. 3, when case lid 3-2 on the MISSILE LAUNCHING case 3 and the compression of the interface between metal frame 3-1 combined type packing ring, axial cross section is on Y shape rubber elastomer 1 sealing surface that is attached to case lid 3-2 tightly, plays the effect of inner sealing; When the pressure in the MISSILE LAUNCHING case 3 during greater than the pressure outside the case, axial cross section is the sealing surface that the inboard of Y shape rubber elastomer 1 is adjacent to case lid 3-2, has guaranteed the sealing of MISSILE LAUNCHING case 3; When the pressure outside the MISSILE LAUNCHING case 3 during greater than the pressure in the case, axial cross section is the sealing surface that the outside of Y shape rubber elastomer 1 is adjacent to case lid 3-2, guaranteed the sealing of MISSILE LAUNCHING case 3, therefore, the combined type rubber seal has two way sealed performance and selfsealings performance.The utility model successful Application in MISSILE LAUNCHING experimentally, experimental result, the combined type rubber seal does not come off, guided missile is launched smoothly.
Claims (2)
1, a kind of combined type packing ring is characterized in that: the axial cross section of described seal ring is made up of Y shape rubber elastomer (1) and inverted T-shaped rubber elastomer (2), and Y shape rubber elastomer (1) is positioned at the top of inverted T-shaped rubber elastomer (2), and the two makes one.
2, combined type packing ring according to claim 1 is characterized in that: described axial cross section is that the elastic compression amount of Y shape rubber elastomer (1) is no more than 1.5mm.
