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, a flange can only be connected to the root pipe, which greatly reduces the engineering efficiency, wastes manpower and material resources, and slows down the construction progress

Embodiment 1

[0055] The multi-pipe connecting flange of the present embodiment, such as figure 1 and figure 2 As shown, it includes a first flange 2, a second flange 4, a sealing gasket 3, a fastening bolt 5 and a nut 1, and the sealing gasket 2 is arranged between the first flange 2 and the second flange 4. The first method Corresponding positions of the flange 2 and the second flange 4 are respectively provided with four tube receiving holes 6 , and the four tube receiving holes 6 are evenly distributed. The corresponding positions of the first flange 2 and the second flange 4 are respectively provided with fastening through holes, the fastening through holes are waist-shaped holes 7, and the fastening through holes of the first flange 2 and the second flange 4 are respectively There are four, and the four fastening through holes are arranged symmetrically in pairs. The fastening bolts 5 pass through the fastening through holes of the first flange 2 and the second flange 4 in turn and...

Embodiment 2

[0094] The multi-pipe connection flange of this embodiment is basically the same as the first embodiment, except that the mass percentages of the components in the first flange and the second flange are: C: 0.11%, Al: 1.25%, Zn: 0.77 %, Si: 0.18%, Mn: 0.72%, S: ≤0.030%, P: ≤0.030%, Cr: 0.17%, Ni: 0.35%, Cu: 0.34%, V: 0.04%, Mo: 0.19%, Ti : 0.56%, B: 0.07%, Pd: 0.19%, Pt: 0.09%, W: 0.31%, Ta: 0.02%, Nd: 0.09%, Ce: 0.07%, Eu: 0.03%, Lu: 0.43%, Au : 0.18%, Ag: 0.73%, Ga: 0.17%, Y: 0.04%, Sn: 0.68%, Zr: 0.13%, Re: 0.04%, Bi: 0.17%, calcium oxide: 0.72%, calcium carbonate: 0.45% , Talc: 0.59%, Magnesium Oxide: 0.27%, Copper Oxide: 0.38%, Iron Oxide: 0.84%, Manganese Dioxide: 0.16%, Potassium Hydroxide: 0.15%, Potassium Nitrate: 0.36%, Calcium Chloride: 0.15 %, Potassium chlorate: 0.19%, the balance being Fe.

Abstract

The invention relates to a multi-pipeline connecting flange which comprises a first flange body, a second flange body, a sealing gasket, fastening bolts and nuts. The sealing gasket is arranged between the first flange body and the second flange body. The corresponding positions of the first flange body and the second flange body are each provided with at least two pipe containing holes and are further each provided with at least two fastening through holes. The fastening bolts sequentially penetrate the fastening through holes of the first flange body and the fastening through holes of the second flange body to be in threaded connection with the nuts. According to the multi-pipeline connecting flange, due to the fact that the corresponding positions of the first flange body and the second flange body are each provided with the at least two pipe containing holes, multiple pipelines can be connected at the same time, the engineering efficiency is greatly improved, manpower and material resources are saved, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to a multi-pipeline connection flange, which 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...
