Description

A kind of rubber sheet gasket with excellent sealing performance

Technical field

The utility model belongs to rubber seal technical field, more particularly to a kind of rubber with excellent sealing performance Gasket.

Background technology

Gasket paper, rubber tissue or copper sheet are made, and are placed on to reinforce the material of sealing between two planes, to prevent fluid Leak the sealing element being arranged between static seal face.

Gasket is the mechanical seal between two objects, usually to prevent from being under pressure between two objects, burn into and Pipeline expands with heat and contract with cold leakage naturally.Since machining surface can not possibly be perfect, scrambling can be filled up using gasket.Pad Piece is usually made of flaky material, such as packing paper, rubber, silicon rubber, cork, felt, neoprene, nitrile rubber, glass fibre Or plastic polymer.

Invention content

The purpose of this utility model is to provide a kind of rubber sheet gaskets with excellent sealing performance, in the madial wall of gasket It is equipped with sealing ring with upper and lower two surface, strengthens the sealing performance of gasket.

In order to solve the above technical problems, the utility model is achieved through the following technical solutions：

The utility model is a kind of rubber sheet gasket with excellent sealing performance, including shim body, the shim body Circumferential lateral surface be laid with several first blind holes；The internal face of the shim body is between shim body central axial direction etc. Away from equipped with several first sealing rings；One surface of the shim body is equidistantly equipped with several second along shim body center of circle direction Sealing ring is also laid with several second blind holes on one surface of the shim body；Two surface textures of the shim body It is identical.

Further, the quantity of first blind hole is 3-48, the pad that the hole depth of first blind hole is 0.1-0.5 times Piece body thickness, the shim body height that aperture is 0.1-0.3 times.

Further, the quantity of first sealing ring is 3-10, and the internal diameter of first sealing ring is 0.9-0.95 The internal diameter of times shim body, the height of first sealing ring are the height of 0.01-0.05 times of shim body.

Further, the height of second sealing ring is the height of 0.01-0.05 times of shim body, second sealing The quantity of circle is 2-5.

Further, the quantity of second blind hole is 3-48；The pad that the hole depth of second blind hole is 0.1-0.3 times Piece body height, the shim body thickness that aperture is 0.1-0.5 times.

The utility model has the advantages that：

The utility model is equipped with sealing ring in the madial wall of gasket and upper and lower two surface, strengthens the sealing performance of gasket； The utility model opens up several blind holes on the ontology of gasket, and the deformation quantity of shim body stress is improved using blind hole so that Gasket, which has, preferably fills up the scrambling on mechanical organ surface, while by the blind hole that two surfaces are equipped with above and below gasket, Air is discharged when blind hole stress, utilizes external air pressure so that gasket is preferably contacted with mechanical organ surface, to carry Mechanical sealing performance between high two objects of gasket pair.

Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.
