Abstract

The invention discloses a mirror face ceramic sealing washer and a manufacturing method thereof, and relates to the technical field of sealing washers. The mirror face ceramic sealing washer comprisesa ceramic washer body, and the washer body is cylindrical and comprises a first end face, a second end face and a cylindrical cavity formed along the axis position; the first end face is a mirror face; and a first chamfer and a second chamfer are formed along the outer edges of the first end face and the second end face correspondingly, and a third chamfer and a fourth chamfer are formed along the inner edges of the first end face and the second end face correspondingly. The mirror face ceramic sealing washer is simple in structure, low in cost, resistant to the high temperature, high pressure and corrosion, and good in sealing effect, batch machining and production are easy, and the mirror face ceramic sealing washer is suitable for most of sealing devices on the market.

Description

technical field [0001] The invention relates to the technical field of sealing gaskets, in particular to a mirror ceramic sealing gasket and a manufacturing method thereof. Background technique [0002] The sealing gasket is a material placed between two planes to strengthen the seal, and it is a sealing element arranged between the static sealing surfaces to prevent fluid leakage. Due to the different chemical properties of the sealing materials, there are high requirements for the high temperature resistance, high pressure resistance and corrosion resistance of the sealing gasket. The traditional sealing gaskets are mostly made of rubber or metal materials. Although they are easy to process, they are not safe to use. They are easily deformed by high temperature and high pressure, or corroded, which will affect the service life, and even cause leakage of sealing materials, which brings safety. Hidden danger. [0003] In view of the above situation, a new technology is urg...
