Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 to 5, the sealing ring with good sealing effect according to the present invention includes a sealing ring main body 1, an auxiliary sealing piece 11 is formed at an upper end of an outer wall of the sealing ring main body 1, a lower end of the auxiliary sealing piece 11 is integrally connected to the sealing ring main body 1, and a V-shaped groove 12 with an upper opening is formed between the auxiliary sealing piece 11 and the sealing ring main body 1; at least one annular sealing convex strip 13 is formed on the outer wall of the sealing ring main body 1 below the auxiliary sealing sheet 11.

Preferably, the utility model relates to a sealed effectual sealing washer and pipeline seal structure, can flow in inner tube 2 and the outer tube 3 and have liquid, supplementary gasket 11 with annular seal sand grip 13 plays the gap between shutoff inner tube 2 and the outer tube 3, guarantees the normal use of pipeline. Through setting up V-arrangement groove 12 and supplementary gasket 11, liquid pressure is big more, and the tension at V-arrangement groove 12 both ends is big more, the sealed effect between supplementary gasket 11 and the outer tube 3 inner wall is better.

Preferably, the upper end of the auxiliary seal piece 11 is higher than the upper end surface of the seal ring body 1. This increases the height of the auxiliary seal fin 11, and improves the sealing effect between the auxiliary seal fin 11 and the inner wall of the outer tube 3.
