The utility model for solving the problems of the technologies described above adopted technical scheme is: it comprises flange portion and fixing shell ring portion, the L shaped plate that the cross-sectional plane in flange portion and fixing shell ring portion is formed in one.
The long limit of described L shaped plate forms fixing shell ring portion, and the minor face of described L shaped plate forms flange portion.
The long limit of described L shaped plate forms flange portion, and the minor face of described L shaped plate forms fixing shell ring portion.
Be provided with ring seal platform at the upper surface of flange portion, the height of ring seal platform is higher than the upper surface of flange portion.
Described ring seal platform is positioned at inside the upper surface of flange portion.
Annular seal groove is provided with at the upper surface of ring seal platform.
The cross-sectional plane of described annular seal groove is V-arrangement.
Described L shaped plate is L shape aluminium alloy plate.
Flange portion is provided with bolt mounting holes.
Described L shaped plate is integrated extrusion forming.
The utility model adopts such scheme, has the following advantages:
1, the L shaped plate that is formed in one of the cross-sectional plane in flange portion of the present utility model and fixing shell ring portion, namely flange portion and fixing shell ring portion are welded after being rolled by integrated L shaped plate, weld after the flange portion that instead of splicing structure in prior art will roll respectively with fixing shell ring portion, and then by technique that flange portion is welded with fixing shell ring portion, not only reduce stitching portion and the weld seam quantity of sheet material, add structural strength, and simplify manufacturing procedure, ensure that working accuracy, improve production efficiency.
2, be provided with ring seal platform at the upper surface of flange portion, the height of ring seal platform is higher than the upper surface of flange portion; Annular seal groove is provided with at the upper surface of ring seal platform; The cross-sectional plane of annular seal groove is V-arrangement.Such a construction ensures the leak tightness that capping and flange portion cover.
3, L shaped plate is integrated extrusion forming.L shaped plate is by extrusion forming, not only reduces the impact of multiple welding on plate property, and ensure that the intensity of L shaped plate.
4, L shaped plate is L shape aluminium alloy plate.Aluminium alloy plate intensity is high, density is little, withstanding corrosion, easily process, long service life, and well achieves tank vehicle weight-saving object.

Detailed description of the invention
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Fig. 4 ~ Fig. 6, the utility model comprises flange portion 1 and fixing shell ring portion 2, the L shaped plate that the cross-sectional plane in flange portion 1 and fixing shell ring portion 2 is formed in one.L shaped plate is integrated the aluminium alloy plate of extrusion forming.The long limit of L shaped plate forms fixing shell ring portion 2, and the minor face of L shaped plate forms flange portion 1.Or the long limit of L shaped plate forms flange portion 1, the minor face of L shaped plate forms fixing shell ring portion 2.Be provided with ring seal platform 3 at the upper surface of flange portion 1, the height of ring seal platform 3 is higher than the upper surface of flange portion 1.Ring seal platform 3 is positioned at inside the upper surface of flange portion 1.Annular seal groove 4 is provided with at the upper surface of ring seal platform 3.The cross-sectional plane of annular seal groove 4 is V-arrangement.Flange portion 1 is provided with bolt mounting holes 5.
The L shaped plate that the cross-sectional plane in flange portion 1 of the present utility model and fixing shell ring portion 2 is formed in one, namely flange portion 1 and fixing shell ring portion 2 are welded after being rolled by integrated L shaped plate, weld seam 6 is provided with in the side in flange portion 1 and fixing shell ring portion 2, weld after the flange portion 1 that instead of splicing structure in prior art will roll respectively with fixing shell ring portion 2, and then by technique that flange portion 1 is welded with fixing shell ring portion 2, not only reduce stitching portion and the weld seam quantity of sheet material, add structural strength, and simplify manufacturing procedure, ensure that working accuracy, improve production efficiency.
