Abstract
The utility model discloses a sealing gasket of an internal-combustion engine, which is composed of a metal plate and sealing rings. A valve lifter through hole, a cooling water through hole and an oil passing through hole are arranged on the metal plate, and the periphery of the valve lifter through hole, the cooling water through hole and the oil passing through hole of the metal plate is provided with one or more than one sealing ring being convex to two surfaces. The edge of the metal plate is provided with one or more than one sealing ring being convex to two surfaces. The cross section of each sealing ring is trapezoidal, or rectangular, or semicircular or triangular. The contact width of the sealing rings and the metal plate is 0.1-3mm, and the sealing rings are 0.05-3mm higher than the metal plate plane. The sealing gasket of the internal-combustion engine has the characteristics that the sealing effect is good and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of sealing gasket, relates in particular to a kind of internal-combustion engine sealing gasket.
Background technique
Internal-combustion engine (petrol engine and DENG) all relies on fuel burn to produce explosive force in cylinder combustion and promotes piston to-and-fro motion and doing work in cylinder.Sealing of cylinder head (comprising envelope gas, water shutoff, oil sealing) and serviceability are most important, always are the important steps that improves engine performance, and wherein gasket material between engine body and the cylinder head and moulding are the most important things.Early stage sealing gasket adopts horsestone velveteen plate in the double-layer alloy Copper Foil more, and sealing is better but working life is not high; In recent years, adopt the stacked conducting plate embossing again, sealing and working life improve, but working life is still not ideal enough.
Summary of the invention
The utility model provides a kind of good sealing effect, a kind of internal-combustion engine sealing gasket of long service life.
The technological scheme of the utility model technical solution problem is:
A kind of internal-combustion engine sealing gasket; Form by sheet metal and seal ring; On said sheet metal, be provided with valve tappet through hole, cooling water through hole and cross oil hole, at valve tappet through hole, the cooling water through hole of sheet metal with cross oriented biconvex 1 road of outer periphery or the seal ring more than 1 road of oil hole.
Be provided with more than 1 road or 1 to biconvex seal ring in said metal-sheet edges.
The cross section of said seal ring is trapezoidal, or rectangle, or semicircle, or triangle.
Said seal ring and sheet metal contact width are 0.1～3 millimeter, and seal ring exceeds 0.05～3 millimeter on sheet metal plane.
The technique effect of the utility model is: because the utility model adopts individual layer unitary solid sheet metal to process internal-combustion engine sealing gasket main body; At the valve tappet through hole of said sheet metal, cooling water through hole with cross the oriented outer lug seal ring of outer periphery of oil hole; Especially be provided with the above seal ring of twice or twice; Meeting forms multiple-sealed, and forms the sealing buffer strip between the adjacent seals circle, and sealing effect is better.Be provided with the seal ring that at least 1 road seals in said metal-sheet edges, can increase the sealing effect of whole sealing gasket.When the utility model adopts multiple-sealed circle, can get per pass seal ring size design less.Therefore, the good sealing effect of the utility model, can further improve working life, and manufacture cost reduces.
Description of drawings
Fig. 1 is the utility model IC engine cylinder head pad partial front elevation view.
Fig. 2 be among Fig. 1 A-A to amplification view.
Among the figure: 1. sheet metal, 2. seal ring, 3. valve tappet through hole, 4. the cooling water through hole is 5. crossed oil hole, 6. bolt hole, 7. cylinder-bore.
Embodiment
Specify below in conjunction with accompanying drawing and embodiment:
As depicted in figs. 1 and 2, a kind of internal combustion engine cylinder cover spacer comprises sheet metal 1 and seal ring 2; On the two sides of sheet metal 1, at valve tappet through hole 3, cooling water through hole 4, cross the seal ring 2 of the oriented outer lug of outer periphery of oil hole 5, seal ring is generally 2 roads or more than 2 roads; Sometimes also 1 road can be set, in the present embodiment, the valve tappet through hole 3 peripheral seal rings that are provided with are 3 roads; The periphery of cooling water through hole is provided with 2 road seal rings; The seal ring of crossing the periphery setting of oil hole 5 is 1 road, can select according to the quantity of different situations seal ring, can obtain the better seal effect.Be provided with the seal ring 2 to outer lug on said sheet metal 1 edge two sides, seal ring is generally 2 roads and more than 2 roads, 1 road seal ring can be set also, is 2 road seal rings in the present embodiment, can obtain good sealing effect.
The material of present embodiment sheet metal 1 is carbon steel 08F, and this material has very strong high temperature resistant, high voltage bearing performance, can stand the impact of HTHP for a long time.The material of present embodiment seal ring 2 adopts high temperature resistant, high voltage bearing fluorine rubber; Heat with specialized mould; Bonding or adopt compacting, injecting method peripheral through hot vulcanization process attached to through hole, to valve tappet through hole, the cooling water through hole of easy generation seepage with cross oil hole and have good sealing effect.
The cross section of said seal ring 2 can also can be rectangle, semicircle or triangle for trapezoidal.The cross section of present embodiment seal ring 2 is trapezoidal, and sealing effect is excellent good.
Said seal ring and sheet metal contact width are 0.1～3 millimeter, and seal ring exceeds 0.05～3 millimeter on sheet metal plane.In the present embodiment, the trapezoidal preferred size of seal ring cross section is: seal ring 2 is 1～2.5 millimeter with sheet metal 1 contact width, and seal ring 2 exceeds 0.1～2 millimeter on the plane of sheet metal 1, and the top width of seal ring 2 is 0.5～1.8 millimeter.
Receive the time spent of doing of cylinder bolt when seal ring 2; Seal ring 2 receives very big pressure because of lifting surface area is very little; Cause protruding seal ring 2 small slit between cylinder cap and body fully to be filled up; Fill to the two-side elastic distortion the most easily on the top of especially trapezoidal seal ring, and the sealings of valve tappet through hole 3, cooling water through hole 4 and mistake oil hole 5 peripheries are improved greatly.
Present embodiment is fit to all types of internal-combustion engines, comprises petrol engine and DENG, and be applicable to that other prevents to leak gas, leakage of oil, the sealing gasket that leaks.
