Abstract
The utility model relates to a graphite sealing structure which comprises a sealing static ring assembly, a graphite ring, a rubber ring and a wave spring. One side of the graphite ring is inserted in a graphite ring seat and the other side contacts with the sealing assembly. The graphite ring seat is installed inside the sealing static ring assembly. The wave spring is pressed between the sealing static ring assembly and the graphite ring seat. A groove for installing the rubber ring is designed at the sealing static ring assembly. The width of the groove is greater than the diameter of the rubber ring. The graphite sealing structure will not damage the graphite ring during usage due to no direct effect of the spring on the graphite ring and can effectively avoid the rubber ring to be blocked and damaged by properly broadening the size of the groove for installing the rubber ring in the sealing static ring assembly.
Description
Technical field
The utility model patent relates to a kind of sealing configuration, especially a kind of graphite grazing structure.
Background technique
Show the graphite grazing structure as shown in Figure 1, this graphite grazing is comprised of frame set, graphite annulus 2, cushion rubber 1, pressing plate 4, wavy spring 3.In the existing scheme, frame set passes to active force on the graphite annulus by wavy spring 3 and pressing plate 4, and mineralization pressure consists of end face seal between graphite annulus and the Sealing.Two coating surfaces and auxiliary seal are realized its sealing function in relative rotation for Sealing, graphite annulus during work.This kind face seals ability to work is high, good seal performance, and frictional power loss is little.
But in this kind end face seal structure, graphite annulus bears the fracture that axial force that wavy spring applies easily causes graphite annulus, assembles simultaneously that the too small cushion rubber that easily causes of size design blocks in groove between the stationary ring at cushion rubber place and clamp, damages cushion rubber.
Summary of the invention
The purpose of this utility model provides a kind of graphite grazing structure, when can realize effective sealing, guarantees that graphite annulus does not rupture, cushion rubber is difficult for blocking and causes damage.
The technical solution of the utility model is: the graphite grazing structure comprises stationary seal ring assembly, graphite annulus, cushion rubber, wavy spring, described graphite annulus one side is embedded in the graphite ring seat, opposite side contacts with Sealing, the graphite ring seat is installed in the stationary seal ring holder assembly, wavy spring is pressed between stationary seal ring assembly and the graphite ring seat, also be designed with the groove that cushion rubber is installed on the described stationary seal ring assembly, the width of described groove is greater than the diameter of cushion rubber.Also be designed with on described stationary seal ring assembly and the graphite ring seat and prevent from relatively rotating boss.The material of described graphite annulus is metal.
The utility model owing to the effect of wavy spring, pressurizes graphite annulus by the graphite ring seat, thereby has realized sealing effect in use to the Sealing direction.Because spring does not have direct effect to graphite annulus, therefore can not damage graphite annulus; Simultaneously, the graphite ring seat adopts metallic material, can further improve the rigidity of whole stationary seal ring; Cushion rubber is realized auxiliary seal in the stationary seal ring holder assembly, and the suitable broadening of its mounting groove place size improves cushion rubber effective rolling distance in groove, can effectively avoid cushion rubber to block and is damaged.
