Cylinder head gasket assembly with good sealing effect

Abstract

The invention relates to the technical field of engine matching assemblies, in particular to a cylinder head gasket assembly with a good sealing effect. The invention aims to solve the problems that in the prior art, when equipment runs, material breakage is extremely likely to occur at a turnup where a gasket is wrapped by a gasket blocking layer, so an assembly structure between the gasket and the gasket blocking layer loses efficacy, even dislocation and loss of the blocking cushion layer and the gasket are caused, the whole air cylinder sealing structure fails consequently, and the stable operation of an engine system is severely influenced. The cylinder head gasket assembly with the good sealing effect comprises a gasket, wherein the gasket comprises an adjusting layer, and the top and the bottom of the adjusting layer are in clearance fit and are provided with an upper functional layer and a lower functional layer in parallel. According to the invention, the sealing effect of the cylinder head gasket assembly on a cylinder is greatly improved, it is guaranteed that the overall operation of an engine is more stable and reliable, the overall assembly structural stability of the cylinder head gasket assembly is better, and structural strength is further improved.

Description

technical field [0001] The invention relates to the technical field of engine supporting components, in particular to a cylinder gasket component with good sealing effect. Background technique [0002] In the existing structure of the engine cylinder head gasket assembly, a heat-resistant layer and corrugations corresponding to pressurization are usually provided near the cylinder mouth to enhance the sealing effect of the cylinder head gasket on the gas. In practical applications, due to the long-term operation of the engine In the end, there will be deformation of the cylinder head, and at the same time, the increase in performance will lead to insufficient compression of the cylinder head, resulting in leakage. In order to further control the leakage, it is usually located at the periphery of the cylinder in the main structure of the cylinder head gasket assembly. Add gaskets and corrugations to fill the structural gaps after the deformation of the cylinder head and impro...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a cylinder head gasket assembly with good sealing effect, which solves the problems caused by the explosion pressure in the cylinder when it is used in some engine equipment with relatively high working condition pressure in the prior art, especially in some large-displacement engines. If it is too large, it is very easy to cause material breakage at the flange where the gasket is covered by the gasket when the equipment is running, resulting in the failure of the assembly structure between the gasket and the gasket, and even causing dislocation and loss of the gasket and the gasket. , which leads to the failure of the entire cylinder sealing structure, which seriously affects the stable operation of the engine system
