Problems solved by technology
[0003] like figure 1 and figure 2 As shown, the overall frame of the existing cylinder head gasket 10 is designed with a multi-layer sealing structure. The cylinder mouth part 101 and the cylinder head bolt passing nail hole part 102 of the existing cylinder head gasket 10 belong to the same structure as the frame body. Number of seal layers (see figure 2 ), and the metal frame adopts multi-layer metal plates as a whole. This design can meet the sealing effect of the cylinder block, but there are many consumables and high cost
[0004] Therefore, the metal frame of the cylinder head gasket in the prior art adopts multi-layer metal plates as a whole, which has many consumables and high cost, and cannot save materials

Embodiment Construction
[0017] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0018] The cylinder head gasket of the present invention has different sealing requirements in different parts of the frame body. By designing a single-layer frame body with a multi-layer sealing structure except for the cylinder mouth part, it can save energy while ensuring the sealing function of the cylinder head gasket. consumables.
[0019] Such as image 3 and Figure 4 As shown, the cylinder head gasket provided in this embodiment includes a frame body 1 and a pressure bearing plate 2. The frame body 1 has a cylinder mouth portion 11 and a cylinder head bolt hole portion 12. The frame body 1 is made of a metal plate as a whole. However, the cylinder mouth part 11 adopts multi-layer metal plates, generally desi...

The invention discloses an air cylinder cover gasket which comprises a frame body and bearing plates, wherein the frame body is provided with a cylinder mouth part and cylinder cover bolt tack hole parts; the frame body is a single-layer plate except the cylinder mouth part; the cylinder mouth part is a multi-layer plate; and the bearing plates are separately arranged at the cylinder cover bolt tack hole parts and used for adjusting the whole surface pressure of the air cylinder cover gasket. According to the air cylinder cover gasket, the cylinder mouth part and the cylinder cover bolt tack hole parts of the air cylinder cover gasket are separately designed, so that sealing of an air cylinder is ensured, a material is saved, and the air cylinder cover gasket is environment-friendly.
Description
technical field [0001] The invention relates to the field of engine cylinder blocks, in particular to a cylinder head gasket. Background technique [0002] Cylinder head gasket, referred to as cylinder gasket, is an elastic sealing element placed between the cylinder block and the cylinder head. Since it is impossible to be absolutely flat between the cylinder block and the cylinder head, a cylinder head gasket is required to prevent high-pressure gas, lubricating oil and cooling water from escaping from between them. With the development of engine technology, most engines currently use multi-layer (2 or more layers) metal cylinder head gaskets. This solution can achieve effective sealing of high-pressure gas in the cylinder, and because the metal frame as a whole uses Therefore, the surface pressure of the cylinder head gasket is more uniform, and the reliability of the cylinder head gasket is better. [0003] Such as figure 1 and figure 2 As shown, the overall frame o...
