Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, a metal tooth-shaped gasket includes a metal sheet 1, a metal convex ring 10 is fixedly mounted at the top end of the metal sheet 1, a cavity 4 is formed at the top end of the metal convex ring 10, a graphite plate 5 is fixedly mounted at the bottom end inside the cavity 4, the graphite plate 5 is made of a soft material, and therefore can slightly deform when being pressed, a convex strip 3 is fixedly mounted at the top end of the graphite plate 5, a through hole 6 which completely penetrates through the top end of the metal sheet 1 is formed in the top end of the metal sheet, and a stop block 9 is arranged in the through hole 6.

Furthermore, the shape of the metal convex ring 10 is circular ring shape, the number of the metal convex rings 10 is six, the metal convex rings 10 are concentrically and divergently arranged at the top end of the metal sheet 1, and the circle centers of the metal convex rings 10 are the same and are distributed in concentric circle shape, so that the metal convex rings can bear pressure uniformly.

Furthermore, the tooth-shaped grooves 2 are arranged between the metal convex rings 10, the number of the cavities 4 is eight, the cavities are arranged at the top ends of the innermost metal convex ring 10 and the outermost metal convex ring 10 at equal angles, and the cavities 4 are respectively arranged at the upper, lower, left and right positions of the two sides to enable the convex strips 3 to bear the pressure from the flange connecting surface uniformly.

Furthermore, the number of the graphite plates 5 in the cavity 4 is two and the graphite plates are respectively installed at the upper end and the lower end of the cavity 4, the shape of the convex strip 3 is the same as that of the cavity 4, and the height of the convex strip 3 is higher than that of the metal convex ring 10, so that the convex strip 3 is ensured to be firstly contacted with the flange joint surface but not the metal convex ring 10, and the metal convex ring 10 is prevented from being crushed.

Further, the number of the through holes 6 is eight and the through holes 6 are opened at the top ends of the innermost side and the outermost side of the metal sheet 1 at equal angles, and since the through holes 6 are through holes and have a height lower than that of the metal sheet 1, the liquid inevitably flows to the through holes 6, so that the liquid can be guided to the positions of the outermost side and the innermost side to prevent the liquid from contacting the metal gasket.

Further, the inside fixed mounting of dog 9 has pivot 8, and the equal movable mounting in both ends about pivot 8 has installation piece 7, and one side that dog 9 was kept away from to installation piece 7 and the inside wall fixed connection of through-hole 6 to can relatively rotate when installation piece 7 receives the effort under the effect of pivot 8.

The working principle is as follows: this metal profile of tooth gasket is when using, place this gasket in two flange joint departments, because with flange joint face the first contact be sand grip 3 and not metal bulge loop 10, the top of sand grip 3 is the fillet design simultaneously, when the gasket receives pressure, the graphite cake 5 of 3 bottoms of sand grip produce deformation, sand grip 3 middle part itself can produce deformation simultaneously and bear the pressure that comes from the flange joint face, when the corrosive liquids that flange joint face produced drips the metal gasket, liquid can flow to through-hole 6 department, dog 9 receives the effort, pivot 8 drives dog 9 and rotates certain angle, with liquid discharge metal gasket.
