CN203384362U - Magnetic sealing gasket - Google Patents

Abstract

The utility model relates to a magnetic sealing gasket which comprises a rubber sealing gasket body. A through hole is formed in the middle of the sealing gasket body, a magnetic layer is arranged on the lower bottom face of the sealing gasket body, a fiber layer is arranged in the middle of the sealing gasket body, and the fiber layer is made of graphite fibers with the purity higher than 95%. According to the magnetic sealing gasket, the magnetic layer is arranged, grooves or edges and corners are not required to be arranged any more, a rubber ring of the magnetic sealing gasket can be easily fixed and prevented from shifting, the sealing effect is improved, meanwhile, the fiber layer is arranged, the structural intensity of the magnetic sealing gasket is strengthened, and the service life of the magnetic sealing gasket is prolonged.

Description

A kind of magnetic gasket

Technical field

The utility model relates to the sealed product technical field, relates in particular to the magnetic gasket that between a kind of engine air cylinder cap and engine cylinder-body, joint is sealed.

Background technique

As everyone knows, the sealability of motor is the important parameter of engine operation.Therefore, in order to ensure motor, there is good sealability, at the respectively place of being tightly connected of motor, sealing gasket is set, by sealing gasket, the corresponding place of being tightly connected is sealed.In prior art, the sealing gasket arranged in the body joint of engine air cylinder cap and engine cylinder, this gasket structure intensity difference, in engine working process, because violent vibrations easily produce damage, reduce its working life, simultaneously when carrying out end face seal, fixedly groove or the corner angle of cushion rubber need to be set on the part part, otherwise cushion rubber is difficult for fixing.

The model utility content

The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of magnetic gasket is provided.

The utility model is to be achieved through the following technical solutions:

A kind of magnetic gasket, comprise rubber gasket, and the centre of described sealing gasket has through hole, and the bottom surface of described sealing gasket is provided with magnetic layer, and the centre of described sealing gasket is provided with layer of fibers.

Further, described layer of fibers adopts purity to be greater than 95% graphite fiber to make.

Further, described fibrolaminar thickness is 2.2-3.6mm.

Further, described magnetic layer and sealing gasket glue molding, described magnetospheric thickness is 0.7mm.

Compared with prior art, the beneficial effects of the utility model are: the utility model arranges magnetic layer, no longer needs to arrange groove or corner angle, makes the cushion rubber of sealing gasket be easy to fix, and prevents that cushion rubber is offset, and improves sealing effect; By layer of fibers is set, strengthen the structural strength of sealing gasket simultaneously, improve its working life.
