Description

Technical Field

[0001] This utility model relates to the field of insulating sheet technology, and in particular to an insulating gasket with good sealing performance. Background Technology

[0002] In process equipment across various industrial sectors, gaskets play a crucial role. The quality of the seal directly impacts production continuity, property safety, energy conservation, environmental protection, and public health. Therefore, the development of gaskets is receiving increasing attention, with new requirements constantly being placed on gasket sealing. Various new materials and structures are emerging, each with significantly different sealing performance. This is especially true in pipeline connections within the petroleum and chemical industries, where insulating gaskets are often required. However, current insulating gaskets typically use resin materials, which have relatively low strength. When transporting high-pressure materials, such as natural gas, these materials are prone to bending, leading to leaks and further causing safety and economic losses. Utility Model Content

[0003] The main purpose of this utility model is to provide an insulating gasket with good sealing performance to solve the above-mentioned technical problems. It can ensure the tensile strength of the insulating gasket and has excellent chemical stability, corrosion resistance, sealing performance, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An insulating gasket with good sealing performance includes a sealing body, an elastomer, and a gasket body. The elastomer is mounted on the gasket body, and the sealing body abuts against the elastomer. The gasket body includes a rubber layer, a first protective layer, and a first metal layer. The first protective layer is coated on the outer surface of the first metal layer, and the rubber layer is hot-pressed onto the surface of the first protective layer. The sealing body is provided with a second protective layer, a second metal layer, and a sealing ring. The second protective layer is coated on the outer surface of the second metal layer, and a mounting groove is provided on the outer end face of the second metal layer. The sealing ring is installed in the mounting groove.

[0006] As a preferred technical solution, the first protective layer and the second protective layer are polytetrafluoroethylene layers.

[0007] As a preferred technical solution, the gasket body is provided with mounting holes for installation.

[0008] As a preferred technical solution, the end of the mounting hole is provided with a guide slope.

[0009] As a preferred technical solution, a fixing groove is provided on the side of the first metal layer, and the elastomer is installed in the fixing groove.

[0010] As a preferred technical solution, the elastomer is a C-shaped elastic tube.

[0011] As a preferred technical solution, the inner surface of the fixing groove is provided with a protruding ring, which is engaged with the opening of the elastic body.

[0012] As a preferred technical solution, a limiting protrusion is provided at the end of the fixing groove, and an anti-detachment protrusion is provided on the inner side of the sealing body, with the limiting protrusion abutting against the anti-detachment protrusion.

[0013] The beneficial effects of this utility model are as follows: the above-mentioned insulating gasket with good sealing performance is made of high-strength steel for the first and second metal layers, which can ensure the tensile strength of the insulating gasket. The first and second protective layers are made of polytetrafluoroethylene (PTFE). PTFE has excellent chemical stability, corrosion resistance, sealing performance, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance, thus meeting the sealing requirements of different pipelines. It is fixed to the pipeline by bolts passing through the mounting holes. Because the rubber material itself has good compression and rebound properties, it can provide good sealing performance and can also be used as a gasket. After the bolts are installed, it can have a high sealing performance. Attached Figure Description
