Abstract
The utility model relates to a multilayer metal air cylinder gasket with combined multiple seal ribs, which includes a gasket body, wherein air cylinder holes, bolt holes, oil holes, water holes, locating hole and tappet holes are arranged in the gasket body; the gasket body is formed by four or more layers of metal plates; the high pressure gas combustion sealing of the air cylinder is realized through an arc seal rib and an inclined seal rib that are identical in position and inverse in direction, or two arc seal ribs with different heights, as well as the thickness difference between upper and lower plates at the cylinder port, and further, the arc rib and the inclined rib are formed by two layers of metal plates through suppressing; in addition, seal coatings are applied between layers and on upper and lower surfaces of the gasket. The utility model has the benefits as follows: compared with existing relevant products, the laminated metal cylinder gasket is nicer in design and more reasonable in structure, uses pollution-free material, facilitates environment protection, has excellent sealing effect and high pressure resistance, remarkably improves the reliability and durability of the engine, and is suitable for being popularized and used in relevant technical fields.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of internal-combustion engine and uses the lamination type Metallilc gasket.
Background technique
Between engine body and the cylinder cap head gasket is housed, in order to sealed high pressure combustion gas, lubricant oil and cooling water.Mostly domestic head gasket is that Ashestos plate and spurt iron plate are composited at present, is main with Ashestos plate wherein, and harmful because of its befouling environment, abroad some developed countries have forbidden producing.The cylinder mouth of asbestos composite sheet pad, water hole guard ring adopt the metal bound edge to process more, and this structure withstand voltage properties is poor, and sealability is also poor, and motor is prone to towards cylinder, leaks.Recently, the producer that has adopts single circular arc sealed muscle sealing combustion gas, but performance is bad, and stability is poor.
The model utility content
The purpose of the utility model is in order to solve deficiency of the prior art, a kind of good seal performance, withstand voltage, environmentally friendly multiple layer Metallilc gasket with the many sealed muscles of combined type to be provided.
The utility model comprises pad and is mounted thereon the casing bore of portion, bolt hole, water hole, oilhole and tappet bore that wherein, pad is to be made up of the sheet metal more than four layers or four layers.
Circular hole arc sealed muscle that the sealing of the high-pressure gas of the utility model cylinder-bore is lean on that the compacting of double layer of metal plate forms in the opposite direction, the position is identical and inclination shape sealed muscle and realize sealing with the thickness difference of cylinder mouth place's upper plate and lower plate; Water hole, oilhole and tappet bore all are to be employed in relative, the reverse trapezoidal ripple formation sealing of compacting formation on the double layer of metal plate; The upper and lower faces that reaches pad between the layer of pad and the layer all is coated with gasket coating.
When the utility model oilhole is the high pressure oilhole, adopt backbone sealing ring to seal.
The effect that the utility model is useful is: the utility model is compared with existing Related product, and is more perfect in the design, more reasonable on the structure; Material therefor is pollution-free; Help environmental protection, good sealing effect, withstand voltage properties is strong; Improved reliability, the durability of motor significantly, be adapted at promoting the use of in the correlative technology field.

Embodiment
For the technological scheme and the characteristics that make the utility model are clearer,, the utility model is done further detailed description below in conjunction with embodiment and accompanying drawing.At this, following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Like Fig. 1-shown in Figure 6, the utility model comprises pad 1 and is mounted thereon the casing bore 2 of portion, bolt hole 3, water hole 4, oilhole 5 and tappet bore 6 that wherein, pad 1 is to be made up of the sheet metal more than four layers or four layers.
Circular hole arc sealed muscle that the sealing of the high-pressure gas of the utility model cylinder-bore 2 is lean on that the compacting of double layer of metal plate forms in the opposite direction, the position is identical and inclination shape sealed muscle and realize sealing with the thickness difference of cylinder mouth place's upper plate and lower plate; Water hole 4, oilhole 5 and tappet bore 6 all are to be employed in relative, the reverse trapezoidal ripple formation sealing of compacting formation on the double layer of metal plate; The upper and lower faces that reaches pad 1 between the layer of pad 1 and the layer all is coated with gasket coating.This structural design can reach better sealing effect.
In addition, when the utility model oilhole 5 is the high pressure oilhole, adopt backbone sealing ring to seal.This structural design can reach better sealing effect.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all mode of executions.Conspicuous variation that every technological scheme that belongs to the utility model is extended out or change still are in the row of the protection domain of the utility model.
Claims (2)
1. an internal-combustion engine is used the lamination type Metallilc gasket; Comprise cylinder-bore, bolt hole, water hole, oilhole and tappet bore are installed on pad, the pad; It is characterized in that pad is to be made up of the sheet metal more than four layers or four layers, circular hole arc sealed muscle that the sealing of the high-pressure gas of cylinder-bore is lean on that the compacting of double layer of metal plate forms in the opposite direction, the position is identical and inclination shape sealed muscle and seal with the thickness difference of cylinder mouth place's upper plate and lower plate; Water hole, oilhole and tappet bore all are to be employed in relative, the reverse trapezoidal ripple formation sealing of compacting formation on the double layer of metal plate; The upper and lower faces that reaches pad between the layer of pad and the layer all is coated with gasket coating.
