Referring to fig. 1 to 3, the working principle of the present embodiment is as follows: sealing pad 3 sets up between last flange 1 and lower flange 2, presses the back in upper and lower flange 2, and the annular that will seal up 3 is protruding inwards to extrude and be the plane and seal up the clearance between flange 1 and the lower flange 2 completely, consequently can strengthen the leakproofness greatly, prevents the fluid seepage, and still be equipped with sealed piece 20 and seal up and peg graft and realize the sealed effect of multilayer in slot 10, increase and strengthen sealing performance.

Referring to fig. 1 to 3, the flange sealing structure includes an upper flange 1, a lower flange 2 and a sealing gasket 3, the sealing gasket 3 is embedded between the upper flange 1 and the lower flange 2, the upper flange 1 and the lower flange 2 are fixed by bolts, the sealing gasket 3 is made of rubber, a plurality of annular protrusions 30 are arranged at the upper end and the lower end of the left side and the right side of the sealing gasket 3, the annular protrusions 30 at the upper end and the lower end of the sealing gasket 3 are respectively abutted against and pressed by the upper flange 1 and the lower flange 2 to form a plane, and sealing components are arranged at the two sides of the upper flange 1 and the lower flange 2.

Referring to fig. 1 to 2, as a modified embodiment, the annular protrusion 30 is a triangular or circular or rectangular or polygonal ring-shaped body.

Made of rubber, the annular bulge 30 can extend outwards after being extruded, the sealing surface is increased, and the sealing performance is enhanced.
