Description

Technical Field

[0001] The utility model belongs to the field of engine accessories and relates to a cylinder gasket, in particular to a high temperature resistant, tight and leakproof cylinder gasket. Background Art

[0002] The cylinder gasket is located between the cylinder head and the cylinder block and is also called the cylinder bed. Its function is to fill the microscopic gap between the cylinder block and the cylinder head to ensure good sealing at the joint surface, thereby ensuring the sealing of the combustion chamber to prevent cylinder air leakage and water jacket leakage.

[0003] The existing cylinder gasket with an integrated structural design has a graphite or other non-asbestos sheet material on the outside, a thin steel sheet edge on the inner ring, and steel wire embedded inside the steel sheet. It is an integral sealing structure, which has the following defects: the thickness of the cylinder gasket is limited by space and compression deformation, and is generally made thinner. When subjected to the impact of the cylinder working pressure and high-temperature gas, the connection between two adjacent cylinder holes is often easily burned or punctured, causing damage to the cylinder gasket, a short service life and a high replacement cost. Summary of the invention

[0004] The utility model aims to solve the above problems in the prior art by providing a high temperature resistant, tight and leakproof cylinder gasket.

[0005] The purpose of the utility model can be achieved through the following technical solutions: A high temperature resistant, tight and leakproof cylinder gasket, comprising a cylinder gasket body, the cylinder gasket body having a plurality of cylinder holes, characterized in that an inner ring assembly for improving the sealing strength is arranged in contact with the inner peripheral wall of the cylinder hole, the inner ring assembly and the corresponding cylinder hole are arranged in a split structure, and are connected by a concave-convex inlay matching structure;

[0006] The inner ring assembly comprises an inner connecting ring connected to the inner peripheral wall of the cylinder hole in a concave-convex manner and used to improve the connection strength, a connecting frame located between the connecting ring and the inner peripheral wall of the cylinder hole, and a reinforcing steel ring embedded on the outer side wall of the inner connecting ring;

[0007] The inner peripheral wall of the inner connecting ring is provided with a guide ring groove for guiding the impact of high-temperature gas;

[0008] The cross section of the guide ring groove is arranged in a V-shaped structure;

[0009] The outer side wall of the inner connecting ring is provided with an installation ring groove for the reinforcing steel ring to be embedded and installed therein, and the reinforcing steel ring is located between the inner connecting ring and the connecting frame.

[0010] In the above-mentioned high-temperature resistant, tight and leak-proof cylinder gasket, the cross-section of the connecting frame is arranged in an "I"-shaped structure. The connecting frame is located between the connection ring and the cylinder hole connection and is used to improve the connection strength of the connection.

[0011] In the above-mentioned high-temperature resistant, tight and leak-proof cylinder gasket, the reinforcing steel ring is arranged in a hollow structure, the reinforcing steel ring corresponds to the guide ring groove, and the reinforcing steel ring is made of aluminum-copper-lithium heat-resistant alloy.

[0012] In the above-mentioned high-temperature resistant, tight and leak-proof cylinder gasket, the inner connecting ring is made of high-temperature resistant graphite as a material, and a stainless steel wire braided mesh is used as a connecting skeleton.

[0013] Compared with the prior art, the high-temperature resistant, tight and leak-proof cylinder gasket has a simple structural design. It utilizes the cooperation of an inner connecting ring, a connecting frame and a reinforcing steel ring structure to effectively improve the heat resistance and impact resistance of the connection between two adjacent cylinder holes in the cylinder gasket body, and effectively prevents the relatively weak connection from being easily burned or punctured.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, the high temperature resistant tight leakproof cylinder gasket comprises a cylinder gasket body 1, the cylinder gasket body 1 has a plurality of cylinder holes 2, an inner ring assembly for improving the sealing strength is arranged in contact with the inner circumference of the cylinder hole 2, the inner ring assembly and the corresponding cylinder hole 2 are arranged in a split structure, and are connected by a concave-convex inlay matching structure, the inner ring assembly comprises an inner connecting ring 3 which is connected to the inner circumference of the cylinder hole 2 in a concave-convex matching manner and is used to improve the connection strength, a connecting skeleton 4 between the connecting ring and the inner circumference of the cylinder hole 2, and a reinforcing steel ring 5 inlaid on the outer side wall of the inner connecting ring 3, and the inner circumference of the inner connecting ring 3 is provided. A guide ring groove 6 is arranged on the wall for guiding the impact of high-temperature gas. The cross-section of the guide ring groove 6 is V-shaped. An installation ring groove 7 for the reinforcing steel ring 5 to be embedded and installed is opened on the outer wall of the inner connecting ring 3. The reinforcing steel ring 5 is located between the inner connecting ring 3 and the connecting skeleton 4. The structure is simple in design. The cooperation of the inner connecting ring 3, the connecting skeleton 4 and the reinforcing steel ring 5 can effectively improve the heat resistance and impact resistance of the connection between two adjacent cylinder holes 2 in the cylinder gasket body 1, and effectively prevent the problem of easy ablation or breakdown of the relatively weak connection.

[0020] To further elaborate, in order to improve the impact resistance and heat resistance of the cylinder hole 2, the cross-section of the connecting skeleton 4 is set in an "I"-shaped structure. The connecting skeleton 4 is located between the connection between the inner connecting ring 3 and the cylinder hole 2, and is used to improve the connection strength of the connection.

[0021] To further elaborate, in order to improve the impact resistance of the inner connecting ring 3, the reinforcing steel ring 5 is arranged in a hollow structure, the reinforcing steel ring 5 corresponds to the guide ring groove 6, and the reinforcing steel ring 5 is made of aluminum-copper-lithium heat-resistant alloy. The aluminum-copper-lithium heat-resistant alloy is an aluminum-lithium alloy developed on the basis of high-strength aluminum alloy with lithium replacing magnesium. It has the characteristics of low density, large elastic modulus, high strength and good heat resistance, which effectively improves the heat resistance and strength of the cylinder gasket body 1. At the same time, the reinforcing steel ring 5 corresponds to the guide ring groove 6, which can effectively absorb the stress of the larger impact force under the diversion effect and alleviate the impact strength.

[0022] To be more specific, the inner connecting ring 3 is made of high temperature resistant graphite and the stainless steel wire mesh is used as the connecting skeleton 4 .

[0023] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0024] Although the terms such as cylinder gasket body 1, cylinder hole 2, inner connecting ring 3, connecting frame 4, reinforcing steel ring 5, guide ring groove 6, and mounting ring groove 7 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
