Wear-resistant Y-shaped rubber sealing ring

Abstract

The utility model relates to the field of sealing rings, and discloses a wear-resistant Y-shaped rubber sealing ring which comprises a shell, a groove is formed in the surface of the shell, a sealing layer is fixedly connected to the inner wall of the groove of the shell, a reinforcing frame is fixedly connected to the bottom end of the inner wall of the groove of the shell, an outer lip edge is fixedly connected to the outer cambered surface of the shell, and the outer lip edge is fixedly connected to the outer cambered surface of the shell. The inner side arc face of the shell is fixedly connected with an inner lip edge, the shell comprises a base layer outer wall, the top end of the base layer outer wall is fixedly connected with a hard wear-resistant high-temperature-resistant coating, and the top end of the base layer outer wall is fixedly connected with an elastic wear-resistant coating. According to the sealing ring, due to the design of the arch-shaped sealing layer and the X-shaped reinforcing frame, the connection strength of the lip part and the base part is greatly improved, the situation that the lip part and the base part are separated due to stress in the long-term use process is effectively prevented, and the stable structure can better disperse pressure, reduce local abrasion and maintain the shape and the sealing performance of the sealing ring; therefore, the service life of the sealing ring is prolonged.
