Abstract
The utility model discloses a buffering formula graphite seal ring, including first graphite layer and second graphite layer, be equipped with the buffer layer between first graphite layer and the second graphite layer, one side that first graphite layer is close to the buffer layer evenly is equipped with two at least first archs, one side that second graphite layer is close to the buffer layer evenly is equipped with two at least second archs, the second is protruding to distribute with first arch is crisscross, one side that the buffer layer is close to first graphite layer is equipped with the first recess that corresponds with first arch, one side that the buffer layer is close to second graphite layer is equipped with the second recess that corresponds with the second arch. This graphite seal ring simple structure is reasonable, and it is convenient to make, and through addding being connected between buffer layer and rational design buffer layer and the graphite layer, the atress is more even, has effectively improved the holistic mechanical properties of sealing ring to improve the life of spare part and even whole platform equipment.
Description
Technical field
This utility model relates to a kind of sealing ring, is specifically related to a kind of buffer-type graphite-seal ring.
Background technology
It is strong that graphite seal has corrosion-resistant, non-oxidizability, and the characteristics such as resistance is low, are indispensable parts in modern efficient machinery. But the deadly defect of graphite material sealing member is, mechanical strength is very low, very fragile, the very easily embrittlement when discontinuity, pulverizing, considerably reduces parts or even the service life of whole equipment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and reasonable, easily manufactured, has the buffer-type graphite-seal ring of better mechanical performance.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of buffer-type graphite-seal ring, including the first graphite linings and the second graphite linings, it is provided with cushion between first graphite linings and the second graphite linings, it is protruding that first graphite linings is uniformly provided with at least two first near the side of cushion, it is protruding that second graphite linings is uniformly provided with at least two second near the side of cushion, second projection is interspersed with the first projection, cushion is provided with near the side of the first graphite linings and first protruding the first corresponding groove, and cushion is provided with near the side of the second graphite linings and second protruding the second corresponding groove.
The described first protruding Stripwise construction being two ends arc transition with the second projection.
The sectional area of described first groove is less than the sectional area of the first projection, and the sectional area of the second groove is less than the sectional area of the second projection.
The outer rim of described cushion is uniformly provided with the notch of at least two arc.
Described cushion is silicone rubber material.
Compared with prior art, the utility model has the advantages that: graphite-seal ring of the present utility model is simple and reasonable, easily manufactured, by setting up the connection between cushion and appropriate design cushion and graphite linings, stress is evenly, it is effectively increased the mechanical performance that sealing ring is overall, thus improving parts or even the service life of whole equipment.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the first graphite linings in this utility model;
Fig. 3 is the structural representation of the second graphite linings in this utility model;
Fig. 4 is the structural representation of cushion in this utility model.
Wherein, the 1, first graphite linings, 2, cushion, the 3, second graphite linings, 4, first is protruding, the 41, first groove, and 5, second is protruding, the 51, second groove, and 6, notch.
Detailed description of the invention:
As shown in Figures 1 to 4, a kind of buffer-type graphite-seal ring, including the first graphite linings 1 and the second graphite linings 3, the cushion 2 of silicone rubber material it is provided with between first graphite linings 1 and the second graphite linings 3, first 1 layer of graphite is uniformly provided with at least two the first projection 4 near the side of cushion 2, second graphite linings 3 is uniformly provided with at least two the second projection 5 near the side of cushion 2, second protruding 5 and first projection 4 is interspersed, and first protruding 4 and second projection 5 be the Stripwise construction of two ends arc transition, cushion 2 is provided with 4 corresponding first grooves 41 protruding with first near the side of the first graphite linings 1, cushion 2 is provided with 5 corresponding second grooves 51 protruding with second near the side of the second graphite linings 3. by cushion 2 alleviate two-layer graphite linings by force intensity, and stress is evenly, is effectively increased the service life of parts or even whole the equipment using this utility model graphite seal.
In this utility model, the sectional area of the first groove 41 is less than the sectional area of the first projection 4, and the sectional area of the second groove 51 is less than the sectional area of the second projection 5, so that the connectivity between each graphite linings and cushion 2 is better; The outer rim of cushion 2 is uniformly provided with the notch 6 of at least two arc, is conducive to overcoming the part elastic force of cushion 2 self, increases deformation, and pressure bearing scope is bigger.
Claims (5)
