Description

Technical Field

[0001] The utility model relates to the technical field of loose flanges, in particular to a quick-detachable loose flange. Background Art

[0002] Flanges are parts that connect pipes to each other and are used to connect the ends of pipes. That is, two pipes, pipe fittings or equipment are first fixed on a flange plate respectively, and the two flange plates are fastened together by bolts to complete the connection between the pipes.

[0003] Loose flanges are also used for pipeline connections. The flange is integrated with the pipeline, that is, the end of the pipeline is flanging, and the flange is pre-inserted into the pipeline before flanging. The flanging is the sealing surface, and the loose flange is used to tighten the flanging. The loose flange does not contact the medium, and the loose flange is not connected to the pipeline, and can be put on the pipeline and move freely.

[0004] Most existing loose flanges are integral, and the pipe and flange are combined together and cannot be separated. That is, during production, the loose flange is first put on the pipe, and then the two ends of the pipe are flanged. After flanged, the flange cannot be removed from the pipe. This integral structure has the following disadvantages: first, the production efficiency is low; second, it takes up a lot of space during transportation and loading; third, during construction, if the pipe is replaced, the attached flange needs to be discarded as a whole, and the replacement cost is high. Utility Model Content

[0005] The utility model aims to solve the above problem and provides a quick-detachable loose flange.

[0006] The utility model is realized through the following technical scheme: a quick detachable loose flange, characterized in that it comprises two semicircular ring bodies with the same structure, each semicircular ring body is provided with no less than two bolt holes, an inlay block is provided at the middle of one end of the semicircular ring body, square grooves are provided on both sides of the inlay block, an inlay groove adapted to the inlay block is provided at the middle of the other end, square blocks are provided on both sides of the inlay groove, the inlay block is composed of a square handle and a disc, and the disc is arranged at the lower end of the square handle.

[0007] Furthermore, each of the semicircular rings is designed to be integrally formed.

[0008] Furthermore, the two semicircular ring bodies are connected by embedding the embedding protrusion into the embedding groove and the square protrusion into the square groove to form a loose flange.

[0009] Compared with the traditional integral loose flange, the utility model has the following beneficial effects:

[0010] 1. During production, there is no need to consider the need to pre-install the flange on the pipe, which improves production efficiency;

[0011] 2. When transported by truck, the pipelines are arranged compactly, the transportation efficiency is high, and they can be assembled at any time when used;

[0012] 3. The construction is convenient and flexible. When replacing the pipeline, the utility model can be removed at any time to reduce the replacement cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with embodiments.

[0020] like Figures 1 to 5 As shown, a quick-detachable loose flange comprises two semicircular ring bodies 1 of the same structure, each semicircular ring body 1 is provided with no less than two bolt holes 2, that is, two to several bolt holes 2, an inlay convex block 3 is provided in the middle of one end of the semicircular ring body 1, and square grooves 4 are provided on both sides of the inlay convex block 3, and an inlay groove 5 adapted to the inlay convex block 3 is provided in the middle of the other end, and square convex blocks 6 are provided on both sides of the inlay groove 5, as shown in FIG. Figure 4 As shown, the inlaid protrusion 3 is composed of a square handle 31 and a round piece 32. The round piece 32 is arranged at the lower end of the square handle 31. Each of the semicircular ring bodies 1 is designed to be integrally formed.

[0021] The two semicircular ring bodies 1 are connected by embedding the embedding protrusion 3 into the embedding groove 5 and the square protrusion 6 into the square groove 4 to form a loose flange.

[0022] The splicing method of the loose flange is as follows: the inlaying protrusion 3 at the left end of a semicircular ring body 1 is inserted into the inlaying groove 5 of the other semicircular ring body 1 corresponding thereto, and the square protrusions 6 on both sides of the inlaying groove 5 are inserted into the corresponding square grooves 4; similarly, the inlaying groove 5 at the right end of the semicircular ring body 1 is connected with the inlaying protrusion 3 of the other semicircular ring body 1, and the square protrusion 6 is correspondingly connected with the square groove 4, and finally spliced ​​into an integral circular loose flange.

[0023] like Figure 5 As shown, the connection method of the loose flange 8 is as follows: the two pipes 7 to be connected are butted together, that is, the flanges 9 are butted against the flanges 9 and a sealing ring 10 is padded at the butt joint of the flanges, and then a loose flange 8 is assembled on each pipe, and the two loose flanges 8 are connected by bolts 11 passing through the bolt holes 2 to tightly connect the two pipes 7 together.

[0024] Except for the technical features described in the specification, the other technical features are known technologies to those skilled in the art.
