Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example (b): referring to fig. 1 and 2, the application scenario of this embodiment is that, in actual construction, a right-angle pipe (a square air pipe) is mainly used for tapping an original pipe (e.g., a pipe 3 in fig. 3) and externally connecting a pipe (e.g., a pipe 4 in fig. 3 or 4) perpendicular to the original pipe. At the moment, construction is carried out, namely a flange, namely a first flange 1 in the drawing, is mounted on two cut end surfaces of the original pipeline;

the specific structure of the first flange 1 is as follows: the structure comprises a first buckle plate 11, wherein the end part of the first buckle plate 11 is vertically turned over towards one side and extends to form a flange end plate 12, and one end, far away from the first buckle plate 11, of the flange end plate 12 is vertically turned over towards one side and extends to form a second buckle plate 13;

and an assembly cavity A for inserting an air supply pipe is defined by the second buckling plate 13 and the first buckling plate 11. On the whole, the flange can be obtained by integral casting, the structure is simple, and during installation, steel plates on two sides of the air pipe only need to be inserted into the assembly cavity A.

In addition, in order to reduce heat transfer, a heat insulation cavity 14 structure is arranged on the outer side of the flange;

it is worth mentioning that the flange is made of aluminum alloy, so that the flange has high heat conductivity coefficient, condensation and dew formation at the flange are easy to generate, and the heat insulation and cold insulation effects of the air pipe connected are poor; the function of the insulating chamber 14 is to reduce the heat transfer between the two connecting flanges.

It is then necessary that the insulating chamber 14 is located at the junction of the two flanges, and in this case, as shown in fig. 1 and 2, the first gusset 11 is located on the outside of the flange, which is just for connection with the outside, so the insulating chamber 14 needs to be located between the outside face of the flange and the junction face with the outside.

Formation of the specific insulating cavity 14: at least one transition plate is required to be led out from the flange towards the outer side direction of the flange, the outer side end of the plate forms a connecting part 17, and the transition plate extends out, namely the space between the connecting part 17 and the flange is a heat insulation cavity 14;

for the optimization of the structure, referring to fig. 2, a section of transition plate is led out from the flange end face plate 12, and then a section of extension plate is led out from the first pinch plate 11, a connecting part 17 is fixedly connected to the end parts of the two plates together, the connecting part 17 is used for being connected with another flange, and a sawtooth structure 15 is arranged on the end face of the connecting part 17 for increasing friction.

At one end of the connecting portion 17, the engagement end 16 is extended and folded back.

Referring again to fig. 4, reference numerals 31 and 32 show two cross-sections of the original pipe 3, which are cut off and exposed. After the flanges are installed on the two sections, four installation positions, namely an upper installation position, a lower installation position, a left installation position and a right installation position, are formed, and the upper end of the installation position is externally connected with a pipeline 4 in the embodiment as an example;

another flange, namely the second flange 2, is required to be inserted at the end part of the external pipeline 4;

as shown in the figure, the second flange 2 is provided with a mounting cavity B, and the mounting cavity B is perpendicular to the mounting cavity a; in addition, the bottom surface (for reference in the figure) of the assembly cavity B is provided with a connecting surface 22, a heat insulation cavity (also marked in the figure) similar to the first flange 1 can be also arranged here, and one side of the connecting surface is connected with a clamping end 21;

during installation, the two flanges are butted according to the figure 1, the two clamping ends are fixed by adopting a C-shaped part 5, after the clamping ends are fixed, the connecting surface 22 is attached to the connecting part 17, and the pipeline 4 is communicated with the pipeline 3.
