Abstract
The invention discloses a graphite ring used for producing powder. The graphite ring is characterized in that the graphite ring comprises a graphite belt and a metal belt; the graphite belt and the metal belt are arranged in parallel; the graphite belt is wound to be in a disc shape; and annular protrusions are arranged on the outer surface of the graphite belt. The graphite ring has the beneficial effects that the sealing strength problem of the graphite ring is solved; the metal belt in the graphite ring is beneficial to enhancement of the strength of the graphite ring; and the annular protrusions are beneficial to enhancement of the friction between the graphite ring and other parts.
Description
Technical field
The present invention relates to field of machining, particularly relate to a kind of graphite annulus for producing powder body.
Background technology
Existing graphite annulus is typically to be worked out filler by flexible graphite belt or soft graphite, is made through molding, application
When high-pressure high-temperature environments such as valves, owing to graphite annulus pressure experienced is relatively big, after sealing a period of time,
Service life is short, and graphite annulus can deform, thus causes plant equipment that the gas leakage phenomenon of leakage, the gas of whole mechanism occur
Close property reduces, and affects work efficiency and the service life of plant equipment, even damages the person.
Summary of the invention
The present invention is a kind of graphite for producing powder body provided for solving the sealing intensity problem of graphite annulus
Ring.
The present invention is by the following technological means above-mentioned technical problem of solution: a kind of graphite annulus for producing powder body,
It is characterized in that, including graphite tape and metal tape, described graphite tape be arranged in parallel with described metal tape, described graphite tape be wound around in
Discoid, described graphite tape outer surface is provided with annular projection.This graphite annulus be for internal two parts of graphite heat exchanger it
Between, metal tape is conducive to strengthening the intensity of graphite annulus, and the structure making graphite annulus is more stable, enhances the sealing of graphite annulus
Can, extending the service life of graphite annulus, annular projection is conducive to strengthening the friction between graphite annulus and miscellaneous part, increases close
Feng Xing.
As a further improvement on the present invention, the width of described metal tape be described graphite tape width 1/7～to 1/
4。
Beneficial effects of the present invention: (1) present invention solves the sealing intensity problem of graphite annulus；(2) metal in the present invention
Band is conducive to strengthening the intensity of graphite annulus；(3) annular projection of the present invention is conducive to strengthening between graphite annulus and miscellaneous part
Friction.
