The utility model discloses a split type elastic sealing device, and belongs to the technical field of elastic sealing devices. The split type elastic sealing device is used for elastic sealing between a front steam seal and a front steam cylinder of a turbonator. According to the technical scheme, the split type elastic sealing device is a split type elastic sealing ring, the split type elastic sealing ring is formed by two elastic sealing semi-rings, the sections of the two sealing semi-rings are in a U shape, annular steam cylinder side connecting plates and annular steam seal side connecting plates are arranged on the outer sides and the inner sides of the upper ends of the U-shaped rings respectively, and the opposite end faces of the two sealing semi-rings are connected. The split type elastic sealing device is convenient to dismount, mount and maintain, and the problem caused by mounting and maintenance of the whole elastic sealing ring is avoided. An end sealing device is adopted, radial line sealing is converted into face contact sealing, the sealing area is large, and the effect is good. Expansion resistance is small, the deformation range is large, and the influence of the expansion difference caused by different heat expansion between the front steam seal and the front steam cylinder to the sealing effect is avoided. The steam cylinder interface with the largest expansion deformation is avoided, and the sealing effect is guaranteed.
