description	The utility model discloses a sealing ring for a deeper groove for maintenance. The sealing ring comprises a sealing shell and a U-shaped spring, wherein a U-shaped ring groove is formed in the top surface of the sealing shell; the sealing shell is made of tetrafluoroethylene and comprises a first lip and a second lip which are located on the outer side and the inner side of the sealing shell respectively, the wall thickness between the first lip and the outer side wall of the U-shaped ring groove is larger than the wall thickness between the second lip and the inner side wall of the U-shapedring groove, and a notch ring groove is formed in the periphery of the bottom end of the first lip; and the U-shaped spring is in interference fit in the U-shaped ring groove, and an opening of the U-shaped spring points to the outside of the U-shaped ring groove. The thickness of the wall between the first lip and the outer side wall of the U-shaped ring groove is increased, the notch ring grooveis formed in the peripher
