Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-3, the high-strength sealing gasket of the present embodiment includes a gasket 1, a sealing ring 2 is disposed on a top of the gasket 1, an inner ring 3 is fixedly disposed on an inner wall of the sealing ring 2, a coil spring 5 is embedded inside the inner ring 3, a slope 4 is disposed on a top end of the inner ring 3, an inner diameter of the gasket 1 is the same as an inner diameter of the inner ring 3, the slope 4 is utilized to ensure a supporting effect of the inner ring 3 on the sealing ring 2, extrusion of a connecting component on the inner ring 3 is reduced, and strength of the sealing ring 2.

Wherein, the last fixed surface of packing ring 1 is connected with annular card strip 6, and draw-in groove 7 relative with annular card strip 6 position is seted up to the bottom of sealing washer 2, and annular card strip 6 inlays the inside of locating draw-in groove 7, the dismouting of packing ring 1 of being convenient for, convenient to use.

Wherein, the inner wall of packing ring 1 inlays and is equipped with backup ring 8, and the height of backup ring 8 is less than the height of packing ring 1, utilizes backup ring 8 to increase the intensity of packing ring 1, prevents that packing ring 1 from taking place the invagination phenomenon.

Wherein, a plurality of opening grooves 9 that are trapezoidal shape are seted up to the lower surface of packing ring 1, and when packing ring 1 received the extrusion, the air pressure in 1 bottom opening groove 9 of packing ring reduced, and 1 bottom of packing ring produces the appeal when passing through opening groove 9 and mechanical platform contact, prevents that packing ring 1 from taking place the aversion phenomenon, guarantees the stability when packing ring 1 uses, and the leakproofness is good.

The side of the gasket 1 is an inclined plane, so that the contact area between the gasket 1 and a mechanical platform is increased, the stability of the gasket 1 during operation is ensured, and the stability of the sealing ring 2 is ensured.
