Abstract
The utility model relates to a sealing gasket which is arranged between interface flanges of pipes for sealing. The utility model comprises a sealing ring formed by that metal flat belts and a graphitic layer are stacked together, wherein, the inner and the outer ring surfaces of the sealing ring are both provided with the metal flat belts, and the cross section of each metal flat belt in the sealing ring is in a W shape. The utility model has the advantages of favorable compression elastic structure, strong pressure resistance, simple structure, and convenient production.
Description
The utility model relates to a kind of gasket seal that seals usefulness between pipe interface flange.
Do not leak when docking, need use gasket seal for the flange that makes pipeline.General metal pipe sealing pad all is to overlap into seal ring by the metal bandlet with graphite layer, but the compression capability of this gasket seal is quite limited, need establish stiffening ring at the interior ring of seal ring, has increased manufacturing process difficulty and cost, compression capability is still not high, is easy to crushing.
The purpose of this utility model provides a kind of anti-pressure ability metal pipe sealing pad strong, simple in structure.
The utility model comprises the seal ring that is overlapped and formed by metal bandlet and graphite layer, and the inside and outside anchor ring of seal ring is the metal bandlet, and the cross section of each the metal bandlet in the seal ring is the W type.
Metal bandlet cross section in the seal ring of the present utility model is a W shape, and elastic structure is good during pressurized, and anti-pressure ability is strong, does not need stiffening ring, and is simple in structure, produces more convenient.
Further illustrate the utility model below in conjunction with drawings and Examples.
Fig. 1 is embodiment's a plan view;
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
As shown in the figure, seal ring 2 is overlapped by metal bandlet 1 and graphite layer 3 and forms, and the inside and outside anchor ring of seal ring 2 is metal bandlet 1, and the cross section of each the metal bandlet 1 in the seal ring 2 is W shape.One circle radial depressions is just arranged in the middle of the outer ring surface of seal ring 2 like this, and inner ring surface then should have a circle radial protrusion mutually.Adopt such structure, when seal ring 2 used pressurized, all flexible compression-resistant structure of each metal bandlet 1 made anti-pressure ability bigger.Outer ring surface at seal ring 2 also can be fixed with suspender belt 4, and making can be more convenient when installing.
Claims (2)
1, a kind of metal pipe sealing pad comprises the seal ring that is overlapped and formed by metal bandlet and graphite layer, and the inside and outside anchor ring of seal ring is the metal bandlet, it is characterized by: the cross section of each the metal bandlet (1) in the seal ring (2) is the W type.
2, metal pipe sealing pad according to claim 1 is characterized by: the outer ring surface of seal ring (2) is fixed with suspender belt (4).
