Problems solved by technology

Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand high pressure. In industrial pipelines, flange connection is widely used. However, during the installation or disassembly of ordinary flanges, bolts are required. It is time-consuming and laborious to install or disassemble one by one, and in real life, after the two pipes are connected, the circulating substances need to be filtered, which requires a separate installation of a filter, which wastes a lot of manpower and material resources and slows down Construction Schedule

Embodiment 1

[0054] The fast connection filter flange of this embodiment, such as figure 1 and 2 As shown, including the first flange 3, the second flange 7, the circular strainer 5, the fastening bolts 2 and the nuts 8, the corresponding positions of the first flange 3, the second flange 7 and the circular strainer 5 Four waist-shaped holes 9 are provided respectively, and the four waist-shaped holes 9 are symmetrically arranged in pairs. The fastening bolts 2 pass through the first flange 3, the circular filter screen 5 and the second flange 7 in turn, and are threaded with the nut 8. A sealing gasket 6 is arranged between the first flange 3 and the second flange 7, and there are two sealing gaskets 6, and the two sealing gaskets 6 are arranged on both sides of the circular filter screen 5 respectively, the first flange 3 and the second flange 7 The opposite sides of the two flanges 7 are respectively equipped with pipe joints 1 , and the joints of the first flange 3 and the second flan...

Embodiment 2

[0094] The fast connection filter flange of this embodiment is basically the same as that of Embodiment 1, except that the mass percentages of the components in the first flange 3 and the second flange 7 are: C: 0.31%, Al: 2.23% , Zn: 0.55%, Si: 0.29%, Mn: 0.93%, S: ≤0.030%, P: ≤0.030%, Cr: 0.08%, Ni: 0.19%, Cu: 0.24%, V: 0.03%, Mo: 0.03%, Ti: 0.36%, B: 0.04%, Pd: 0.09%, Pt: 0.13%, W: 0.19%, Ta: 0.05%, Nd: 0.18%, Ce: 0.03%, Eu: 0.05%, Lu: 0.26%, Au: 0.36%, Ag: 0.63%, Ga: 0.03%, Y: 0.14%, Sn: 0.49%, Zr: 0.23%, Re: 0.07%, Os: 0.06%, Hf: 0.21%, Bi: 0.33%, glass fiber: 0.31%, calcium oxide: 0.52%, light calcium carbonate: 0.36%, talcum powder: 0.32%, magnesium oxide: 0.27%, and the balance is Fe.

Abstract

The invention relates to a filter flange fast and convenient to connect. The filter flange comprises a first flange, a second flange, a round filter screen, fastening bolts and nuts. One or more kidney-shaped holes are formed in the corresponding positions of the first flange, the second flange and the round filter screen. Each fastening bolt sequentially penetrates the first flange, the round filter screen and the second flange and is in threaded connection with the corresponding nut. One or more sealing washers are arranged between the first flange and the second flange. When the filter flange fast and convenient to connect is mounted, the first flange, the second flange and the round filter screen can be fixed only by making the bolts sequentially penetrate the kidney-shaped holes, it is not needed to slowly align mounting holes in the first flange, the second flange and the round filter screen in sequence, and therefore mounting efficiency is greatly improved; the flange can be mounted efficiently, fast and conveniently; and the progress of a project can be effectively accelerated.

Description

technical field [0001] The invention relates to a filter flange with fast connection and belongs to the technical field of pipeline connection. Background technique [0002] Flanges are also called flanges or flanges, which are parts that connect pipes to pipes and are connected to pipe ends. There are holes on the flange, and bolts can be worn. It usually refers to opening several holes for fixing on the periphery of a disc-like metal body for connecting other things. The existing flange connection is to fix two pipelines, pipe fittings or equipment respectively on a flange plate first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand high pressure. In industrial pipelines, flange connection is widely used. However, during the installation or disassembly of ordinary flanges, bolts are ...
