Description

Technical Field

[0001] The present invention relates to the technical field of gaskets, in particular to a heat source gasket. Background Art

[0002] Gas turbines, as highly efficient energy conversion devices, are widely used in the power, chemical, and other fields. Heat source gaskets, critical sealing components in gas turbines, have a direct impact on the overall efficiency and operational safety of the equipment. Traditional heat source gaskets are susceptible to deformation and aging in high-temperature and high-pressure environments, resulting in reduced sealing performance and affecting the stable operation of the gas turbine.

[0003] Therefore, developing a new type of heat source gasket to improve its high temperature and high pressure resistance has become an urgent problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-efficiency heat source gasket for a gas turbine, which realizes efficient heat conduction, and at the same time enhances the high temperature and high pressure resistance of the gasket, thereby improving the operating efficiency and stability of the gas turbine.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: a heat source gasket, including an annular gasket, wherein the upper surface of the annular gasket is provided with a plurality of metal concentric rings, and the metal concentric rings are distributed in a wave shape from the inside to the outside; the corresponding positions of the upper surface and the lower surface of the annular gasket are provided with a high-temperature coating, and the lower surface is also provided with a peek material coating.

[0006] Furthermore, the high-temperature coating is arranged on the inner side of the metal concentric ring and the two are not in contact.

[0007] Furthermore, the peek material coating layer corresponds to the metal concentric ring in upper and lower positions, and the width of the peek material coating layer is smaller than the width of the metal concentric ring.

[0008] Furthermore, the width of the high-temperature coating on the upper surface is greater than the width of the high-temperature coating on the lower surface.

[0009] Furthermore, an inner ring edge of the annular gasket is provided with a mounting reinforcement ring, and an upper surface of the mounting reinforcement ring is covered with a high-temperature coating.

[0010] Furthermore, the high-temperature coating is made of talcum powder.

[0011] Furthermore, the area between the high-temperature coating on the upper surface of the annular gasket and the metal concentric ring is the upper specification identification area; the area between the high-temperature coating on the lower surface of the annular gasket and the peek material coating is the lower specification identification area.

[0012] The advantages of this invention over existing technologies include: Its heat source gasket significantly improves heat conduction efficiency and high-temperature resistance through its unique wavy metal concentric ring design, double-layer high-temperature coating, and peek material coating. Furthermore, the addition of a mounting reinforcement ring enhances the gasket's structural strength and installation stability. The inclusion of a specification identification area facilitates quick identification and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", "vertical", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] In the description of the present invention, references to "first feature" and "second feature" may include one or more of these features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features being described. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of these features.

[0018] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0019] The heat source gasket of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Combined with attachment Figure 1-2The specific implementation process of the heat source gasket of the present invention is as follows:

[0021] A heat source gasket includes an annular gasket 1, which serves as a base and has a plurality of metal concentric rings 2 on its upper surface. These concentric rings are distributed in a wave shape from inside to outside to increase the heat conduction area, optimize heat distribution, and improve heat conduction efficiency.

[0022] High-temperature coatings 3 are applied to corresponding locations on the upper and lower surfaces of annular gasket 1. Made of a high-temperature-resistant material, these coatings are designed to resist thermal damage in high-temperature environments. Specifically, high-temperature coating 3 is positioned inside concentric metal ring 2, without direct contact between the two, to prevent damage to the coating caused by concentrated thermal stress.

[0023] The lower surface of the annular gasket 1 is also provided with a peek material coating 4, which has excellent high temperature resistance and corrosion resistance, and corresponds to the metal concentric ring 2 in position above and below, but the width of the peek coating is smaller than the width of the metal concentric ring 2, so as to optimize the heat conduction path, reduce material usage and reduce costs.

[0024] The width of the high-temperature coating 3 on the upper surface is greater than that of the high-temperature coating 3 on the lower surface. This design helps to form a more effective heat conduction path and improve heat conduction efficiency.

[0025] The inner edge of the annular gasket 1 is provided with a mounting reinforcement ring 5 to enhance the structural strength of the gasket and improve the installation stability. The upper surface of the reinforcement ring is also covered with a high-temperature coating 3 to further enhance its high-temperature resistance.

[0026] The high-temperature coating 3 is preferably made of talcum powder because it has excellent high-temperature resistance, thermal conductivity and good adhesion to metal surfaces.

[0027] The area between the high-temperature coating 3 on the upper surface of the annular gasket 1 and the metal concentric ring 2 is set as the upper specification identification area 6, and the area between the high-temperature coating 3 and the peek coating on the lower surface is set as the lower specification identification area 7, which makes it easy for users to quickly identify the gasket specifications.

[0028] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
