The metal C-shaped sealing ring is an annular sealing ring with a C-shaped cross section. The metal C-shaped sealing ring is a one-way sealing structure, and the two side surfaces of the outer surface of the metal C-shaped sealing ring are in contact with the wall surface of the annular groove of the part to form line contact to seal a fluid medium. The C-shaped sealing ring has two structures for axial sealing and radial sealing. For the metal C-shaped sealing ring for axial opening type radial sealing, when the metal C-shaped sealing ring is placed in a corresponding annular groove formed by a shaft and a shell, the inner surface and the outer surface of the metal C-shaped sealing ring are respectively contacted with the wall surface of the annular groove formed by the shaft and the shell by virtue of the pre-tightening elastic force of the metal C-shaped sealing ring to form an initial necessary sealing ratio, after a fluid medium enters, the pressure generated by the medium in the inner cavity of the metal C-shaped sealing ring makes the medium elastically deform and expand outwards, so that the outer surface of the metal C-shaped sealing ring is in closer contact with a rigid body, and the sealing ratio is further improved to seal the fluid medium.

The size precision, surface roughness and shape error of the outer surface of the metal C-shaped sealing ring are one of the determinants of the sealing performance of the metal C-shaped sealing ring. The metal C-shaped sealing ring is formed by stretching, rolling and welding thin-wall plates, and because the plates are too thin, the metal C-shaped sealing ring cannot be clamped after being formed, and therefore the metal C-shaped sealing ring cannot be machined by a conventional method.
