The utility model provides a fluid compensation type combined seal, and relates to the technical field of combined seals. The fluid compensation type combined seal comprises an elastic compensation ring capable of being filled with fluid. A valve is arranged on the elastic compensation ring; when the elastic compensation ring is arranged between the first to-be-sealed body and the second to-be-sealed body in a sleeving mode, the valve can be communicated with the outside, and when the elastic compensation ring is filled with fluid through the valve, the elastic compensation ring can seal the first to-be-sealed body and the second to-be-sealed body. The technical effect that combined sealing is convenient to install is achieved. 本实用新型提供了一种流体补偿式组合密封，涉及组合密封技术领域。流体补偿式组合密封包括可充入流体的弹性补偿环；弹性补偿环上设置有阀门；在弹性补偿环套设在第一待密封体和第二待密封体之间时，阀门能够与外界连通，且在通过阀门向弹性补偿环内充入流体时，弹性补偿环能够密封第一待密封体和第二待密封体。达到了组合密封方便安装的技术效果。
