Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Such as Figure 1-2 As shown, the present invention provides a technical solution: a new loose flange, including a lower flange 1 and an upper flange 2, the hollow inner sides of the lower flange 1 and the upper flange 2 are movably interspersed with flanging flanges Plate 3, the lower flange 1 and the upper flange 2 are provided with four positioning holes in the upper annular array, the lower flange 1 and the upper flange 2 are connected to each other...

Abstract

The invention relates to the technical field related to flange connection, and discloses a novel loose flange. 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.

Description

technical field [0001] The invention relates to the related technical field of flange connection, in particular to a novel loose flange. Background technique [0002] Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Pipe fittings and equipment have their own flanges, which also belong to flange connection. Flange connection is an important connection method in pipeline construction, while loose flange is to use flanging, steel ring, etc. to put the flange on the pipe end. The flange can move on the pipe end, the steel ring or flange is the sealing surface, and the function of the flange is to compress them. It can be seen that the loose flange is not in contact with the medium because it is blocked by the steel ring or flange. [0003] The flanging flanges in the loose flange are close to each other for sealing...
