Abstract

The present invention provides a seal ring structure, which comprises a seal ring member. The seal ring member includes a first ring opening on one side and a second ring opening on the other. A periphery of the first ring opening includes a plurality of leak grooves. When the seal ring member and the valve ball squeeze each other, the plurality of leak grooves can reduce the torque required to rotate the valve ball. A leak-groove length of the plurality of leak grooves is smaller than a seal-ring-member length of the seal ring member. The plurality of leak grooves do not penetrate the seal ring member for avoiding leakage of fluid.
