Background Knowledge：
Design principles of O-ring grooves:
1) Determine groove depth and tolerance according to the calculated compression rate to ensure unchanged working compression rate.
2) Determine the groove width according to the cross-sectional area and groove depth of the sealing ring, and ensure that the cross-sectional area of the groove is larger than the cross-sectional area of the sealing ring.
3) Size of filleted corner of the groove bottom and the groove notch needs to be determined after calculation.Size of filleted corner at the bottom of the groove is mainly related to the cross-sectional area of the groove. It is necessary to ensure that the cross-sectional area of the groove is still larger than the cross-sectional area of the seal ring with the existence of filleted corners. Size of filleted corner of the groove notch affects the extrusion and sealing performance of the sealing ring. According to the relevant literature: when the medium pressure is low, the filleted corner radius of the groove notch should be selected as small as possible on the premise that the sealing ring will not be scratched; when the medium pressure is high, it is recommended to be 0.2 mm ~ 0.24 mm.
