Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to a novel cylinder head gasket. Background Technology

[0002] A cylinder head gasket, or simply cylinder head gasket, is a flexible sealing element placed between the cylinder block and the cylinder head. Since the cylinder block and cylinder head cannot be perfectly flat, a cylinder head gasket is needed to prevent high-pressure gases, lubricating oil, and coolant from leaking between them. When using a cylinder head gasket, the flame seal ring must be installed on top of it. Because the flame seal ring and cylinder head gasket are separate, and the gasket is thin, it is easily bent during transportation, causing the flame seal ring to warp. This can lead to assembly defects such as chipped edges, posing a risk of oil and gas leaks, and ultimately affecting engine performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of cylinder head gasket that addresses the above-mentioned shortcomings of the prior art, reduces assembly failures, avoids affecting engine performance, and has the characteristics of wide applicability and strong practicality.

[0004] The technical solution adopted by this utility model is: a novel cylinder head gasket, including a gasket body, a cylinder hole on the gasket body, a water hole, an oil hole, an air hole and a connecting hole on the outer side of the cylinder hole, a flame seal ring on the cylinder hole, a plurality of connecting pieces on the outer circumference of the flame seal ring, and a connecting groove adapted to the connecting pieces on the gasket body, with the plurality of connecting pieces respectively fixed in the connecting groove.

[0005] As a further improvement, the number of connecting pieces is four, and the four connecting pieces are evenly distributed on the fire sealing ring.

[0006] Furthermore, the gasket body is a single-layer plate structure, and the fire sealing ring is a multi-layer plate structure.

[0007] Furthermore, the thickness of each layer of the fire-sealing ring is 0.25–0.3 mm.

[0008] Furthermore, each layer of the fire-sealing ring is made of stainless steel.

[0009] Furthermore, the connecting piece is fixed in the connecting groove by welding.

[0010] Furthermore, the uppermost steel plate of the fire sealing ring and the connecting piece are an integral structure.

[0011] Furthermore, the fire-sealing ring has an upwardly protruding rib at the center, and the rib is arranged around the fire-sealing ring.

[0012] Beneficial effects

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This utility model discloses a novel cylinder head gasket. A sealing ring is installed on the cylinder bore of the gasket to seal the high-temperature, high-pressure gas inside the cylinder. A connecting piece is installed on the sealing ring and mounted in a connecting groove, then fixed by welding. This secures the sealing ring to the gasket body, effectively preventing it from bending or warping during transportation, thus ensuring its flatness, improving sealing performance, reducing assembly failures, and avoiding impact on engine performance. Furthermore, the sealing ring has raised ribs; when compressed, it provides a strong seal, similar to the sealing effect of a compressed rubber ring, thereby enhancing the gasket's sealing capability and reducing the risk of oil and gas leaks. It is convenient to use and has a wide range of applications. Attached Figure Description

[0017] Among them: 1-gasket body, 2-cylinder bore, 3-fire seal ring, 4-water hole, 5-connecting hole, 6-air hole, 7-oil hole, 8-connecting piece, 9-connecting groove, 10-protruding rib, 11-welding point. Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0019] See Figure 1-2As shown, this utility model discloses a novel cylinder head gasket, comprising a gasket body 1, a cylinder bore 2 on the gasket body 1, a water hole 4, an oil hole 7, an air hole 6, and a connecting hole 5 on the outer side of the cylinder bore 2, a sealing ring 3 on the cylinder bore 2, and multiple connecting pieces 8 on the outer circumference of the sealing ring 3. A connecting groove 9 adapted to the connecting pieces 8 is provided on the gasket body 1, and the multiple connecting pieces 8 are fixed one-to-one in the connecting groove 9. By setting the sealing ring 3 on the cylinder bore 2 of the gasket body 1, it seals the high-temperature and high-pressure gas inside the cylinder. Simultaneously, by setting the connecting pieces 5 on the sealing ring 3 and installing them in the connecting groove 9, they are fixed by welding. The weld points 11 are arranged between the connecting pieces 5 and the connecting groove 9, thus fixing the sealing ring 3 to the gasket body 1. This effectively prevents the sealing ring 3 from being bent or warped during transportation, ensuring the flatness of the sealing ring 3, improving the sealing effect, reducing assembly failures, and avoiding affecting engine performance. Meanwhile, the sealing ring 3 is provided with raised ribs 10, which can achieve a good sealing effect after being pressed, similar to the sealing effect produced by the compression of a rubber ring, thereby strengthening the sealing ability of the gasket and reducing the risk of oil and air leakage.

[0020] Specifically, there are four connecting pieces 8, which are evenly distributed on the fire sealing ring 3. The evenly distributed connecting pieces 8 are fixed on the gasket body 1, resulting in more even force distribution.

[0021] Preferably, the gasket body 1 is a single-layer plate structure, and the fire sealing ring 3 is a multi-layer plate structure. The thickness of each layer of the fire sealing ring 3 is 0.25-0.3mm. Through the combination of elastic ridges and heat-resistant sealant, reliable sealing under high temperature and high pressure conditions can be achieved.

[0022] Furthermore, each layer of the fire seal ring 3 is made of stainless steel. Stainless steel has excellent high temperature resistance and can withstand the continuous high temperature generated when the engine is running, thus avoiding seal failure due to thermal expansion.

[0023] Furthermore, the connecting piece 8 is fixed in the connecting groove 9 by welding, and the welding point 11 is arranged between the connecting piece 5 and the connecting groove 9, which effectively fixes the sealing ring 3 on the gasket body 1 and prevents the sealing ring 3 from being bent or warped during transportation.

[0024] Furthermore, the uppermost steel plate of the fire sealing ring 3 and the connecting piece 8 are an integral structure, which facilitates manufacturing and avoids unevenness in later connection.

[0025] Furthermore, the flame seal ring 3 has an upwardly protruding rib 10 in the middle. The rib 10 is arranged around the flame seal ring 3 to enhance the sealing performance and compensate for the unevenness of the mating surface. Under high pressure working conditions, the rib 10 can fill the micro-pores between the cylinder block and the cylinder head to ensure the sealing of the combustion chamber and avoid problems such as power reduction and increased fuel consumption.

[0026] In this embodiment, a novel cylinder head gasket is used by setting a sealing ring 3 on the cylinder bore 2 of the gasket body 1 to seal the high-temperature, high-pressure gas inside the cylinder. A connecting piece 5 is also provided on the sealing ring 3, and the connecting piece 5 is installed in a connecting groove 9 and fixed by welding. The weld point 11 is arranged between the connecting piece 5 and the connecting groove 9, thus fixing the sealing ring 3 to the gasket body 1. This effectively prevents the sealing ring 3 from being bent or warped during transportation, ensuring the flatness of the sealing ring 3, improving the sealing effect, reducing assembly failures, and avoiding impact on engine performance. Furthermore, the sealing ring 3 has raised ribs 10, which, when compressed, provide a good sealing effect, similar to the sealing effect of a compressed rubber ring, thereby strengthening the gasket's sealing capability and reducing the risk of oil and gas leaks. This novel cylinder head gasket reduces assembly failures, avoids impact on engine performance, and has the characteristics of wide applicability and strong practicality.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
