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): with reference to the flange structure shown in fig. 1, it comprises an assembly chamber 20 into which the air duct is inserted: as can be seen from fig. 2, reference numeral 1 in fig. 2 is a flange, and the main body is a ring-shaped structure and is directly fastened to the air duct.
The assembly cavity 20 is formed by enclosing an inner buckle plate 11, an outer buckle plate 11 and a sealing plate 14 which is fixedly connected to one end of the two buckle plates 11;
the extension board 13: the expansion plate 13 is used for installing external equipment communicated with the air pipe, and the extending direction of the expansion plate is the circumferential direction of the air pipe; as described with reference to fig. the external device may be a valve or a sensor; during installation, the end of the external device is fixed to one side of the expansion plate 13, and then the external device is in butt joint with the air pipe.
A section of transition plate 12 extends from the buckle plate 11 at the inner side towards the direction of the expansion plate 13, and a transition air cavity (a position A in fig. 2) communicated with the air pipe is defined by the buckle plate 11 at the inner side and the transition plate 12 together.
It should be noted that, referring to fig. 1, the inner buckle plate 11 extends out of the transition plate 12 in a straight line, and this section is almost equal to the inner diameter of the air duct (the thicknesses of the buckle plate 11 and the transition plate 12 are omitted), and the inner diameter of the air duct is actually the air duct of the inner cavity of the air duct. Therefore, the formed transition air cavity can be directly communicated with the air duct of the air pipe, and large resistance cannot be caused.
In addition, the flow field formed by the transition air cavity and the air duct of the air duct is just positioned at the inner side of the expansion plate 13, and can be better butted with the air duct after an external device is installed (taking a valve as an example).
And the transition plate 12 is connected with the expansion plate 13 to form a flanging structure, and the flanging structure forms an installation groove B in the figure 2 with an external opening at the outer side of the flange. And a bolt/nut mounting position is provided, so that the installation is convenient.
In order to facilitate the installation of the flange and the air pipe, in another preferred embodiment, the flange is arranged into a split structure and is divided into a first component and a second component, and the components are clamped with each other in multiple sections to form a complete annular flange.
In addition, to accommodate rectangular ductwork, the second assembly is provided as a right angle section and the first assembly is provided as a straight line section.
The clamping structure of the first component sealing plate and the second component sealing plate comprises a connecting strip (which can be made of rubber and plastic materials) extending outwards from the first component sealing plate 14 and a connecting groove 110 positioned on the inner side of the second component sealing plate 14, and when the clamping structure is used, the connecting strip is embedded into the connecting groove 110 to be extruded, tensioned and fixed;
in order to improve the stability, bolts may be provided, which penetrate the sealing plate 14 of the second assembly and the connecting bar, and fix the connecting bar to the sealing plate 14 of the second assembly by means of a screw thread.
In specific implementation, a valve is installed as an example, and fig. 2 is referred to. Inserting a flange 1 on an air pipe 2; the valve 3 is butted against the expansion plate 13, and it is worth mentioning here that the valve 3 is provided with an outward-turned lip (if not, one outward-turned lip can be welded), and in essence, the expansion plate can also be regarded as an outward-turned structure of the flange upper edge (referring to the figure, the outward-turned lip forms the mounting groove B), and the two are combined with each other and fixed by bolts and nuts, because the mounting groove B is scattered, the operation of workers can be facilitated.
When two air pipes are required to be butted, the other section of flange is arranged on the other side of the valve 3 in a mode as shown in figure 2 and then inserted into the air pipe.
