| description | The utility model relates to a polyurethane hydraulic sealing assembly which comprises a split type sealing ring with the internal diameter and external diameter bidirectional seal of a piston, and two supporting baffle rings, wherein the internal diameter and the external diameter of the sealing ring are provided with the same sealing strips, and the sealing ring is provided with a split surface in circumferential direction; each of the baffle rings is composed of a longer cylindrical ring and a round table ring with a conical surface in an integral mode, and the end surface of the round table ring contacts the sealing ring. The polyurethane hydraulic sealing assembly comprises a split type sealing ring with the unidirectional seal of a piston rod, and a check ring, wherein the cross section of the sealing ring is in drum shape and rectangle integrally; the interior and the exterior of the drum-shaped portion are provided with the same sealing strips, and only the interior of the rectangular portion is provided with an inner sealing strip; the check ring is composed of a shorter cylindrical ring and a round table ring with a conical surface in an integral mode, and the end surface of the round table ring contacts the rectangular end of the sealing ring. The utility model has the advantages of simple structure, high safety and reliability, simple maintenance and convenient replacement. |
