Description
Technical field
The utility model is related to engine fittings technical field, and in particular to one kind is used to carry out sealed gas to engine
Cylinder pad.
Background technology
Head gasket is installed between engine cylinder cover and cylinder body, ensures the sealing of head gasket by cylinder bolt, prevents combustion
Gas, cooling water and lubricating oil blowby.Head gasket must be produced by tight seal cylinder high temperature and high pressure gas and through cylinder pad
The cooling water and machine oil with certain pressure flow velocity, and be able to take water, gas and oil corrosion.Traditional head gasket manufacturing process
In often through in head gasket cylinder holes, oilhole and water hole surrounding edge, all-metal sealing circle or colloid seal circle are set, to improve
The sealing property of head gasket.However, these metal o-rings or colloid seal circle processing technology are cumbersome, manufacturing cost is high, corrosion resistant
Corrosion is not strong, so as to influence the performance and used life of head gasket and engine.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of structure design more rationally, manufacturing process is simpler, knot
Structure intensity is high, the more preferable modified form head gasket of sealing property.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：A kind of modified form head gasket, includes
Some cylinder holes are offered on cylinder pad body, body, the periphery of cylinder holes is laid with oilhole, water hole, bolt hole and dowel hole, its
It is characterised by：The body includes the upper epidermis being sequentially overlapped, intermediate layer and layer, and the layer is surrounded by week
Side flange, and layer is located at around cylinder holes provided with cylinder holes flange, the peripheral bead and cylinder holes flange prolong by layer
Stretch bending to form, the upper epidermis, intermediate layer and layer are cladded into one by the peripheral bead and the cylinder holes flange
It is monolithically fabricated the body of head gasket；The circumferential edges in the oilhole and water hole are provided with sealed muscle, and sealed muscle is located at upper epidermis with
Between top layer.
Further, the cylinder holes aperture ratio positioned at intermediate layer is located at upper epidermis and the cylinder holes aperture of layer is big, upper epidermis,
The space that centre position has more behind intermediate layer and layer superposition ring filling, the upper and lower surface difference of reinforcing ring are strengthened using metal
Against upper epidermis and layer, there is provided cushion space during elastic deformation.
Further, the upper epidermis and layer use thickness for 0.30 ± 0.02mm soft state stainless steel；It is described
Intermediate layer uses thickness for 0.35 ± 0.02mm elastic stainless steel.
Further, upper epidermis described in the cylinder holes aperture ratio in the intermediate layer and layer cylinder holes aperture it is big by 3.5 ±
0.03mm；The thickness of the reinforcing ring is 0.20 ± 0.02mm, and width is 1.5 ± 0.02mm.
Further, the height of the sealed muscle is 0.3 ± 0.02mm, and width is 2 ± 0.03mm.
Further, the cylinder holes flange width around the cylinder holes of the layer is 2.8 ± 0.03mm.
The utility model constitutes cylinder pad body using three-ply metal, and passes through layer and its flange（Peripheral bead
With cylinder holes flange）Three ply board is even integral by cladding；And all oilholes, the sealing at water hole position are protected by the sealed muscle in intermediate layer
Barrier, metal or colloid seal circle is not separately provided, all sealed muscles are processed and formed at one time, with simple in construction, easy to process, system
Cause the advantages of low, production efficiency is high.In addition, the sealing at head gasket cylinder holes position is cladded and added by the cylinder holes flange of layer
Strong environmental protection barrier, is amenable to the gas impact of HTHP, is difficult ablation；The sealed muscle on intermediate layer is arranged at, because of material itself
For elastic stainless steel, so under the interaction of power, one of tight band is formed on all oilholes, water hole periphery,
Remain to keep high intensity and elasticity under chronic stress effect, and be difficult by oil, aqueous corrosion, therefore, the head gasket is but also with good
Sealing function.
