Detailed Description

In order to better understand the technical solutions of the present invention for those skilled in the art, the following preferred embodiments of the present invention are described in conjunction with the specific examples, but it should be understood that these descriptions are only for the purpose of further explaining the features and advantages of the present invention, and are not intended to limit the patent requirements of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The invention will be further described with reference to the accompanying drawings and preferred embodiments.

Example 1

Referring to fig. 1 and 2, a compression-resistant sealing ring dedicated for a valve according to this embodiment includes a sealing ring main body in a closed ring shape, where the sealing ring main body includes an inner ring plate 1 and an outer ring plate 2 that are arranged at an interval, the inner ring plate 1 and the outer ring plate 2 are provided with an upper ring plate 3 and a lower ring plate 4 that connect the two, the inner ring plate 1, the outer ring plate 2, the upper ring plate 3 and the lower ring plate 4 surround to form an annular capsule cavity 5, the capsule cavity 5 is provided with a first expanding and squeezing protrusion 6 arranged on the inner ring plate 1 and a second expanding and squeezing protrusion 7 arranged on the outer ring plate 2, the capsule cavity 5 is further provided with a first insertion protrusion 8 and a second insertion protrusion 9 that are inserted between the first expanding and squeezing protrusion 6 and the second expanding and squeezing protrusion 7, the first insertion protrusion 8 is arranged on the upper ring plate 3, the second insertion protrusion 9 is arranged on the lower ring plate 4, a width of an end of the first insertion protrusion 8 close to the second insertion protrusion 9 is smaller than an end far from the second insertion protrusion 9, the width of the second insertion projection 9 at the end close to the first insertion projection 8 is smaller than that at the end far from the first insertion projection 8.

Further, the inner ring plate 1, the outer ring plate 2, the upper ring plate 3 and the lower ring plate 4 are integrally arranged.

Further, the first expanding and extruding protrusion 6 and the inner ring sheet 1 are integrally arranged; the second expanding and extruding bulge 7 and the outer ring plate 2 are arranged integrally.

Further, the first insertion protrusion 8 is integrally arranged with the upper ring plate 3; the second insertion projection 9 is integrally provided with the lower ring 4.

Preferably, the seal ring main body is made of rubber materials.

In this embodiment, when the upper and lower terminal surfaces of the seal ring main body receive a large deformation extrusion force, the upper ring plate 3 is drawn close towards the lower ring plate 4 direction, so that the first insertion protrusion 8 and the second insertion protrusion 9 are gradually inserted between the first expansion protrusion 6 and the second expansion protrusion 7, because the width of the end of the first insertion protrusion 8 close to the second insertion protrusion 9 is smaller than the end far away from the second insertion protrusion 9, and the width of the end of the second insertion protrusion 9 close to the first insertion protrusion 8 is smaller than the end far away from the first insertion protrusion 8, in the process of drawing close towards the lower ring plate 4 direction of the upper ring plate 3, the distance between the first expansion protrusion 6 and the second expansion protrusion 7 is increased, so that the outer wall surfaces of the inner ring plate 1 and the outer ring plate 2 form a deformation radian, the contact area with the workpiece is also gradually increased, and the radial sealing performance is indirectly improved. Wherein, when extrusion force was removed from top to bottom, this sealing washer main part can also realize that the deformation resets.

The utility model relates to a compression-resistant sealing ring special for a valve, which is used as a conventional annular sealing ring when the upper and lower end surfaces of a sealing ring main body are not subjected to larger deformation extrusion force; when the upper end face and the lower end face of the sealing ring main body are subjected to large deformation extrusion forces, the first inserting protrusion and the second inserting protrusion are respectively inserted between the first expanding and extruding protrusion and the second expanding and extruding protrusion, and the distance between the first expanding and extruding protrusion and the second expanding and extruding protrusion is enlarged along with the increase of the insertion force, so that the contact area between the inner ring piece and the outer ring piece and the mounting component is enlarged, and the sealing performance is improved.
