Description

Technical Field

[0001] This utility model relates to the field of sealing technology, specifically a T-shaped sealing ring with a rubber and plastic composite structure. Background Technology

[0002] Rubber O-rings are widely used in machinery, pipeline connections, and the automotive industry to prevent liquid or gas leaks. Traditional O-rings, however, offer less than ideal sealing performance under certain conditions, such as high pressure, high temperature, or significant axial and radial displacement. T-rings, due to their unique structural design, are better suited to complex conditions and provide more reliable sealing performance. However, existing T-rings suffer from issues such as easy deformation and poor wear resistance during installation and use, affecting their service life and sealing effectiveness. Utility Model Content

[0005] Furthermore, the inner and outer diameters of the horizontal portion are D1 and D2, respectively, and the height of the vertical portion is H, satisfying D2 / D1 = 1.5-2.0 and H / D1 = 0.5-0.8.

[0006] Furthermore, the thickness of the sealing lip is T, which satisfies T / D1 = 0.05-0.1.

[0007] Furthermore, the depth of the spiral groove in the vertical part is d, which satisfies d / H = 0.1-0.2.

[0008] Furthermore, the groove is embedded with a wear-resistant layer.

[0009] Compared with existing technologies, the advantages of this invention are: by setting a raised sealing lip and a groove, this invention enhances the sealing effect and wear resistance, effectively preventing liquid or gas leakage. At the same time, the reasonable structural dimension design ensures the structural strength and elasticity of the sealing ring, extending its service life.

[0010] This invention is applicable to complex working conditions such as high pressure and high temperature, and has broad application prospects. Attached Figure Description
