The novel loose flange comprises a lower flange and an upper flange, wherein flanging flange plates are movably inserted into the hollow inner sides of the lower flange and the upper flange in a penetrating mode; the lower flange and the upper flange are connected with each other througha tightening mechanism; the plate surfaces of the two flanging flange plates are in contact with each other and are attached to each other; three corresponding annular embedding grooves are formed inthe attached surfaces of the two flanging flange plates; annular sealing rings are embedded into the two flanging flange plates through the annular embedding grooves; and hollow flow dividing plates are installed at the centers of the inner sides of the two flanging flange plates. According to the novel loose flange, the sealing performance of the flanging flange plates in use is effectively improved, on the premise that the structural matching sealing performance is not influenced, the friction force of the upper flange and the lower flange during movable rotation is effectively increased, the stability of matching installation between the structures is guaranteed, noise generated by flow dividing in the flanging flanges is effectively absorbed and reduced, and the noise of the flange connecting end is reduced.
