Abstract

The invention discloses a sealing gasket which comprises a steel ring and a rubber inner ring, wherein a plurality of embedding grooves are formed in the inner periphery of the steel ring; the section of the rubber inner ring is of a rhombus shape; a plurality of embedding bulges corresponding to the embedding grooves of the steel ring are arranged at the periphery of the rubber inner ring; the rubber inner ring is embedded into the inner periphery of the steel ring through cooperation of the embedding bulges and the embedding grooves. By the adoption of the rhombus-shaped section for the inner ring of the sealing gasket and the adoption of a multi-point fixing structure, the volume of rubber is reduced, so that the filling rate and the compression rate are reduced; the sealing gasket is high in sealing property, not liable to bruise, high in applicability and applicable to various diesel engines.

Description

Gasket seal

Technical field

The present invention relates to engine assembly field, more particularly to a kind of gasket seal.

Background technology

Gasket seal is widely used on a diesel engine, and each system is required for using gasket seal.The effect of gasket seal Primarily to the oil of sealing diesel engine, gas and water, make these media normally circulate in diesel engine, it is ensured that Oil, Water, Gas etc. Can play and work, so as to ensure the normal operation of diesel engine.

It is that filling rate and compression ratio are too big due to due to the existing gasket seal conquassation, causes gasket seal often to occur squeezing Dabbing side, conquassation, and then cause sealing position the phenomenons such as permeability, infiltration occur, affect sealing effectiveness.

The information for being disclosed in the background section is merely intended to increase the understanding of the general background to the present invention, and should not Recognize or imply in any form prior art of the information structure well known to persons skilled in the art when being considered.

Content of the invention

It is an object of the invention to provide a kind of simple and reasonable gasket seal, the inner ring of the gasket seal adopts Pedicellus et Pericarpium Trapae The structure that tee section and multiple spot are fixed reduces rubber volume, so as to reduce filling rate and compression ratio, good airproof performance, and it is difficult pressure Burst, and strong applicability, multiple diesel engines can be applied to.

For achieving the above object, the invention provides a kind of gasket seal, the gasket seal includes：Steel ring, its inner circumferential tool There are multiple interior caulking grooves；And rubber inner ring, it is multiple with the steel ring that its section is that rhombus, the periphery of the rubber inner ring is laid with The corresponding embedded projection of interior caulking groove, the rubber inner ring embedded raised is coordinated so as to be embedded in the steel ring with interior caulking groove by described Inner circumferential.

Preferably, in technique scheme, multiple interior caulking grooves are uniform along the circumference of steel ring inner circumferential, the plurality of embedded projection Circumference along the periphery of rubber inner ring is uniform.

Preferably, in technique scheme, multiple interior caulking grooves are rectangular channel, the plurality of embedded raised convex for rectangle Rise.

Preferably, in technique scheme, interior caulking groove be uniform four along the inner circumferential of steel ring, the embedded projection be along rubber Uniform four in the periphery of glue inner ring.

Compared with prior art, the present invention has the advantages that：The inner ring of the gasket seal adopt diamond-shaped cross-section with And the structure that multiple spot is fixed reduces rubber volume, so as to reduce filling rate and compression ratio, good airproof performance, conquassation is difficult, and Strong applicability, can be applied to multiple diesel engines.

Description of the drawings

Fig. 1 is the structural representation of the gasket seal of the present invention.

Fig. 2 is the cross section structure diagram of the gasket seal of the present invention.

Specific embodiment

Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention Shield scope is not limited by specific embodiment.

Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change Change such as "comprising" or " including " etc. and stated element or ingredient is will be understood to comprise, and do not exclude other units Part or other ingredients.

As depicted in figs. 1 and 2, included according to the concrete structure of the gasket seal of the specific embodiment of the invention：1 He of steel ring The rubber inner ring 2 of 1 inner circumferential of steel ring is laid in, and wherein, the section of rubber inner ring 2 is rhombus, steel ring 1 is embedded in using multiple spot In, rubber volume is reduced, with suitable filling rate and compression ratio, good airproof performance, is difficult conquassation, and strong applicability, energy Enough it is applied to multiple diesel engines.

Specifically, steel ring 1 is laid in the periphery of the gasket seal as the skeleton of gasket seal.The inner circumferential of the steel ring 1 With multiple interior caulking grooves, for embedding rubber inner ring.Preferably, multiple interior caulking grooves are uniform along the circumference of 1 inner circumferential of steel ring.Multiple interior Caulking groove is rectangular channel.

The section of rubber inner ring 2 is rhombus, and its periphery is laid with multiple corresponding with the interior caulking groove of steel ring 1 embedded raised 3, The interior caulking groove with steel ring 1 embedded raised by this of rubber inner ring 2 coordinates the inner circumferential so as to be embedded in steel ring 1, the cutting of rubber inner ring 2 Face is rhombus, reduces rubber volume, with suitable filling rate and compression ratio, good airproof performance, is difficult conquassation, and the suitability By force, multiple diesel engines can be applied to.Preferably, multiple embedded raised circumferences along the periphery of rubber inner ring 2 are uniform.Multiple interior Embedding raised for rectangular preiection.

Preferably, interior caulking groove be uniform four along the inner circumferential of steel ring 1, accordingly, embedded projection be along the outer of rubber inner ring 2 Four of Zhou Junbu.Rubber inner ring 2 is fixed by 4 points of structures with steel ring 1, improves the setting-in jail of rubber inner ring 2 and steel ring 1 Solidity.

To sum up, the structure that the inner ring of the gasket seal is fixed using diamond-shaped cross-section and multiple spot reduces rubber volume, from And reduce filling rate and compression ratio, good airproof performance, conquassation, and strong applicability is difficult, multiple diesel engines can be applied to.

The description of the aforementioned specific illustrative embodiment to the present invention illustrate that and illustration purpose.These descriptions It is not wishing to disclosed precise forms are limited the invention to, and it will be apparent that according to above-mentioned teaching, much can be changed And change.The purpose of selecting and describing the exemplary embodiment is that explaining that the certain principles of the present invention and its reality should With so that those skilled in the art can realize and a variety of exemplary using the present invention and A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
