An object of the utility model is to provide a withstand voltage high temperature resistant flange to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a pressure-resistant high-temperature-resistant flange comprises a pair of forged pipe flanges with the same structure, wherein the close ends of the forged pipe flanges are hermetically connected, and the forged pipe flanges are respectively provided with a buffer structure;

buffer structure is including evenly installing the stay tube on forging the circular arc of pipe flange upper end, the draw-in groove has been seted up to the lateral wall face about in the stay tube, slidable mounting has the bracing piece about in the stay tube, bracing piece left and right sides lateral wall face lower extreme is seted up flutedly, all install first spring in the recess, the first spring other end all is equipped with the fixture block, every it has the baffle to forge common demountable installation on the bracing piece on the pipe flange, the second spring is installed to the bracing piece lower extreme.

Preferably, a connecting plate is mounted between the pair of baffles through a first bolt.

Preferably, the baffle is connected with the support rod through a second bolt.

Preferably, the baffle is of an arc structure.

Preferably, the support tube and the corresponding forged tube flange are of an integrally formed structure.

Compared with the prior art, the beneficial effects of the utility model are that: this withstand voltage high temperature resistant flange is rational in infrastructure, and the modern design is convenient for install, connects the pipe fitting through forging the pipe flange, cushions the shock attenuation through buffer structure to forging the pipe flange joint to the protection of buffering is carried out forging the pipe flange joint.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a pressure-resistant high-temperature-resistant flange comprises a pair of forged pipe flanges 1 with the same structure, wherein the close ends of the forged pipe flanges 1 are hermetically connected, and the forged pipe flanges 1 are respectively provided with a buffer structure 2;

buffer structure 2 has seted up draw-in groove 22 including evenly installing in the stay tube 21 on forging pipe flange 1 upper end circular arc about in the stay tube 21, slidable mounting has bracing piece 23 about in the stay tube 21, and recess 24 has been seted up to bracing piece 23 about both sides wall face lower extreme, all installs first spring 25 in the recess 24, and the first spring 25 other end all is equipped with fixture block 26, and common demountable installation has baffle 27 on every bracing piece 23 of forging pipe flange 1, and second spring 28 is installed to bracing piece 23 lower extreme.

Preferably, the connection plate 4 is mounted between the pair of baffle plates 27 by the first bolt 3.

Preferably, the baffle 27 is connected to the support rod 23 by a second bolt 5.

Preferably, the baffle 27 has an arc-shaped structure.

Preferably, the support tube 21 and the corresponding forged tube flange 1 are integrally formed.

Will forge pipe flange 1 one end and pipe fitting welding, will forge pipe flange 1 and be close to end sealing connection, can cushion the protection to forging pipe flange 1 junction through buffer structure 2, when forging pipe flange 1 junction receives the striking, on the baffle 27 is smashed to the foreign object, form cushioning effect to the interior that baffle 27 received under the effect of second spring 28, thereby cushion the protection to forging pipe flange 1 junction, connect a pair of baffle 27 through connecting plate 4, further protect forging pipe flange 1 junction.

When installing, press fixture block 26 in the recess 24, at this moment, first spring 25 receives the extrusion, insert bracing piece 23 in the stay tube 21, when fixture block 26 removed draw-in groove 22 position, under the effect of first spring 25, it is spacing to carry out bracing piece 23 in draw-in groove 22 with fixture block 26 bullet, on bracing piece 23 is adorned with baffle 27 lock afterwards, fix baffle 27 and bracing piece 23 through first bolt 3, fix connecting plate 4 and baffle 27 through second bolt 5.
