AI Technical Summary

Technical Problem

Existing sealing ring assemblies are prone to deformation when subjected to external pressure, especially permanent deformation under radial force, which affects sealing safety and installation stability.

Method used

It adopts a design of support ring, pressure ring and sealing ring. The support ring and pressure ring are provided with V-shaped grooves. The support part is inserted into the groove and fits against the groove wall. The support ring is inserted into the placement cavity and fixed. The support ring is made of hard material and stores lubricating oil through gaps and grooves. Heat dissipation holes are provided for heat dissipation.

Benefits of technology

Abstract

The utility model discloses a V-shaped sealing ring group with high safety performance, which relates to the technical field of V-shaped sealing rings, and comprises a support ring, a compression ring, a sealing ring and a support ring, V-shaped grooves are fixedly arranged on the upper end surfaces of the compression ring and the sealing ring, support parts matched with the V-shaped grooves are arranged below the support ring and the sealing ring, the support ring is arranged along the circumference of the support parts, and the support ring is connected with the support ring. The sides, away from the sealing ring, of the supporting ring and the pressing ring are planes, a fixing groove is formed in the end, close to the axis, of the V-shaped groove in the circumferential direction, an O-shaped ring is installed in the fixing groove in the circumferential direction, a square groove is formed in the end, away from the axis, of the V-shaped groove in the circumferential direction, and a star-shaped ring is installed in the square groove in the circumferential direction. A plurality of heat dissipation holes are evenly formed in the inner wall of the V-shaped groove in the circumferential direction. The mounting structure has the effect of improving the mounting stability of the sealing ring group.
