Y type sealing washer of making by graphite powder and rubber mix

The utility model provides a Y type sealing washer of making by graphite powder and rubber mix, including the sealing washer body, the sealing washer body is installed on the fast axis, epipharynx on the sealing washer body is parallel with the axis of fast axis with the side of fast axis laminating, through the transition face transition between epipharynx and the outer lip, still through the circular arc transition between the top of epipharynx and the transition face. Lubricating oil still through the circular arc transition between the top of epipharynx and the transition face, and is scribbled on the transition face between epipharynx and outer lip to the unreinforced seal circle that utility model was made by graphite powder and rubber mix, avoids the wearing and tearing of sealing washer self, add wearability and the lubrication action that the graphite powder can improve the sealing washer in rubber, reduce the wearing and tearing of sealing washer and rotatory axle head as far as possible, this sealing washer can bear higher operating pressure, can realize better sealed effect when operating pressure is less than 25MPa, reduces hidden danger safe in utilization.
