[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] This embodiment is a highly durable PTFE O-ring seal.
[0022] like Figures 1-4 As shown, it includes a sealing ring mechanism 1, which includes an O-ring layer 2, a first elastic layer 3, a second elastic layer 4, a wear-resistant coating 5, a storage cover 6, an oil hole 7, a folding cover 8, and a feed port 9. The first elastic layer 3 is located at the lower end of the O-ring layer 2, the second elastic layer 4 is located at the upper end of the O-ring layer 2, the wear-resistant coating 5 is located on the outer wall of the O-ring layer 2, and the storage cover 6 is located at the upper end of the second elastic layer 4.
[0023] The folding cover 8 is located on the lower outer surface of the storage cover 6, and the material inlet 9 is located on one side of the upper outer surface of the storage cover 6; multiple sets of oil holes 7 are respectively opened on the upper end of the outer wall of the storage cover 6, and the number of oil holes 7 is not less than ten sets; the first elastic layer 3 is fixedly connected to the O-ring layer 2, the second elastic layer 4 is fixedly connected to the O-ring layer 2, and the wear-resistant coating 5 is fixedly connected to the O-ring layer 2; the storage cover 6 is fixedly connected to the second elastic layer 4 through the folding cover 8.
[0024] It should be noted that this utility model is a highly durable PTFE O-ring seal. The first elastic layer 3, the second elastic layer 4, and the wear-resistant coating 5 set on the O-ring layer 2 have appropriate elasticity to adapt to the slight deformation of the sealing surface, reducing friction and wear. By injecting rubber lubricant into the storage cover 6 through the feed port 9, and compressing the storage cover 6 under the action of the folding cover 8, the internal rubber lubricant is discharged through the oil hole 7 to lubricate the first elastic layer 3, the second elastic layer 4, and the wear-resistant coating 5. The lubrication by the rubber lubricant increases the softness and anti-aging ability of the rubber, maintains its elasticity, and thus extends its service life.
