Abstract
The utility model relates to a novel multi-layer metal cylinder gasket of a high-power diesel engine, which mainly comprises a gasket body, wherein the gasket body consists of three metal plates of an upper plate, a middle plate and a lower plate which are sequentially stacked from the top to the bottom, the gasket body is provided with a cylinder hole, a bolt hole, a water hole, an oil hole, a push rod hole and a positioning hole. The invention has the advantages that compared with the prior art, the cylinder gasket has stronger sealing performance; and particularly the sealing of cooling liquid and lubrication oil is outstanding, the installation is quick, and the positioning precise is high. Because rubber rings take the same middle plate as the common skeleton, the service life of the engine is obviously prolonged in assembly, and the reliability and the durability are enhanced. The applied material has no pollution, and is beneficial to emission and environmental protection standard reaching.
Description
Technical field
The utility model relates generally to the metal cylinder mat field, mainly is a kind of novel high-power diesel engine multiple layer metal head gasket.
Background technique
Motor sealing outburst combustion gas, cooling liquid and lubricant oil, what use in the past is the compound head gasket that asbestos seal sheet material is made, cylinder mouth guard ring, water hole guard ring be with metal sheet (band) manufacturing, easily towards cylinder, leak, weak strength, the life-span is low, poor stability.And asbestos are harmful, banned use of in the world.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of function admirable is provided, the novel high-power diesel engine multiple layer metal head gasket that environmental protection is stable.
The utility model solves the technological scheme that its technical problem adopts: this novel high-power diesel engine multiple layer metal head gasket, mainly comprise pad, described pad is made up of upper plate, middle plate and lower plate three-ply metal, upper plate, middle plate and lower plate stack gradually from top to bottom, and pad is provided with cylinder-bore, bolt hole, water hole, oilhole, push-rod hole and positioning hole.
Described upper plate wraps middle plate in the edge of cylinder-bore, forms the upper plate flange.
Plate is being suppressed with the arc sealed muscle near upper plate flange place in described.
Described upper plate is suppressed with the sealed muscle that shape is identical, arcuate directions is opposite with lower plate in the edge near pad.
The surface of contact of the surface of contact of the outer surface of described upper plate and lower plate, upper plate and middle plate, lower plate and middle plate all scribbles gasket coating.
In described plate in the water hole, edge's pressure injection of oilhole and push-rod hole is fixed with rubber ring.
Plate is being suppressed with the arc sealed muscle near the place, water hole in described.
The effect that the utility model is useful is: the utility model compared with the prior art, sealability is stronger.Especially, the sealing of cooling liquid and lubricant oil is more outstanding, and the positional accuracy height is installed rapidly.Because rubber ring is to make common skeleton with plate in same, has improved the working life of motor during assembling significantly, has strengthened reliability, durability.Material therefor is pollution-free, favourable discharging and environment protection standard.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, this novel high-power diesel engine multiple layer metal head gasket, mainly comprise pad 1, described pad 1 is made up of upper plate 8, middle plate 9 and lower plate 10 three-ply metals, upper plate 8, middle plate 9 and lower plate 10 stack gradually from top to bottom, be fixed by welding in together between each sheet metal of pad 1, on pad 1, form solder joint 17.Pad 1 is provided with cylinder-bore 2, bolt hole 3, water hole 4, oilhole 5, push-rod hole 6 and positioning hole 7, and upper plate 8 is plate 9 in the edge of cylinder-bore 2 wraps, and forms upper plate flange 11, and the outer surface of upper plate flange 11 scribbles temperature resistant encapsulation coating 15.Middle plate 9 is being suppressed with arc sealed muscle 13 near upper plate flange 11 places, has formed the sealing strip of outburst combustion gas, and to improve sealability, upper plate 8 is suppressed with the sealed muscle 12 that shape is identical, arcuate directions is opposite with lower plate 10 in the edge near pad 1.The outer surface of upper plate 6 and lower plate 10, upper plate 8 all scribble gasket coating 16 with surface of contact, the lower plate 10 of middle plate 9 with the surface of contact of middle plate 9.In plate 9 in the water hole 4, edge's pressure injection of oilhole 5 and push-rod hole 6 is fixed with rubber ring 14, the positional accuracy height, good reliability, after the assembling, rubber ring does not have displacement and changing of the relative positions phenomenon, good stability.Middle plate 9 is being suppressed with arc sealed muscle 13 near 4 places, water hole.
The head gasket rigidity of the utility model structure is strong, and good airproof performance can significantly improve working life of motor, increases reliability, and durability is increased work efficiency, the favorable environment protection.The utility model is mainly used in high-power diesel engine, but the also adopting by reference of middle low power motor.Required manufacturing tooling device and technology are simple, invest little.
In addition to the implementation, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
