Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a novel flange forging with high corrosion resistance. Background Art

[0002] Flange, also known as flange or flange, is a part that connects pipes to each other. It is connected to the pipe end. There are holes on the flange, and bolts connect the two flanges tightly. The flanges are sealed with gaskets. Flange is a disc-shaped part, which is most common in pipeline engineering. Flanges are used in pairs. In pipeline engineering, flanges are mainly used to connect pipes. A flange is installed at each end of the two pipes that need to be connected.

[0003] The outer surface of the existing flange has poor corrosion resistance, and the surface of the flange is easily corroded, which reduces the overall service life of the flange and reduces its practicality. At the same time, the flange with an anti-corrosion layer does not have the function of protecting the anti-corrosion layer. External collisions can easily cause damage to the anti-corrosion layer, causing flange corrosion and reducing the service life of the flange. Utility Model Content

[0004] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the utility model proposes a new type of flange forging with high corrosion resistance, including a first flange, a second flange is provided at the bottom of the first flange, the outer surfaces of the first flange and the second flange are both provided with an anti-corrosion layer, and the outer surface of the anti-corrosion layer is provided with a protective layer.

[0005] Preferably, a through hole is formed in the first flange, and a screw rod passing through the through hole is fixedly mounted on the end surface of the second flange close to the first flange, and a nut is threadedly mounted on the screw rod.

[0006] Preferably, a first annular groove is formed on the lower end surface of the first flange, a first rubber sealing ring is provided in the first annular groove, and an outer surface of one side of the first rubber sealing ring contacts the upper end surface of the second flange.

[0007] Preferably, a second annular groove is formed on the upper end surface of the second flange and located outside the first rubber sealing ring, a second rubber sealing ring is arranged in the second annular groove, and the outer surface of one side of the second rubber sealing ring contacts the lower end surface of the first flange.

[0008] Preferably, a rubber sealing gasket is provided on the upper end surface of the second flange, and the upper end surface of the rubber sealing gasket contacts the lower end surface of the first flange.

[0009] The beneficial technical effects of the utility model are as follows: under the action of the anti-corrosion layer, the outer surfaces of the first flange and the second flange can be protected from corrosion, thereby preventing external liquid from eroding the first flange and the second flange and causing damage thereto;

[0010] At the same time, under the action of the protective layer, the anti-corrosion layer can be protected to prevent the first flange and the second flange from being damaged by external collisions during use, so that the surface of the first flange or the second flange is exposed and the exposed surface is corroded, which brings convenience to people.

DETAILED DESCRIPTION

[0013] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0014] The utility model proposes a novel flange forging with high corrosion resistance, comprising a first flange 1, a second flange 2 being provided at the bottom of the first flange 1, an anti-corrosion layer 3 being provided on the outer surfaces of the first flange 1 and the second flange 2, and a protective layer 4 being provided on the outer surface of the anti-corrosion layer 3;

[0015] The end surfaces of the first flange 1 and the second flange 2 that are away from each other are fixedly connected with pipes. Under the action of the first flange 1 and the second flange 2, a pair of pipes can be connected. At the same time, the anti-corrosion layer 3 is phenolic varnish, which is sprayed on the outer surfaces of the first flange 1 and the second flange 2, and can prevent the first flange 1 and the second flange 2 from corrosion. The protective layer 4 is an alloy spraying material, which is sprayed on the outer surface of the anti-corrosion layer 3, and can protect the anti-corrosion layer 3 to prevent damage to the anti-corrosion layer 3 and cause corrosion of the first flange 1 or the second flange 2.

[0016] Specifically, a through hole 5 is formed in the first flange 1, and a screw 6 passing through the through hole 5 is fixedly installed on the end surface of the second flange 2 close to the first flange 1, and a nut 7 is threadedly installed on the screw 6;

[0017] Under the action of the through hole 5 , the screw rod 6 and the nut 7 , the first flange 1 and the second flange 2 can be fixed to each other.

[0018] Specifically, a first annular groove 8 is formed on the lower end surface of the first flange 1, and a first rubber sealing ring 9 is provided in the first annular groove 8. The outer surface of one side of the first rubber sealing ring 9 contacts the upper end surface of the second flange 2;

[0019] The first rubber sealing ring 9 can seal the gap between the first flange 1 and the second flange 2 to prevent leakage.

[0020] Specifically, a second annular groove 10 is formed on the upper end surface of the second flange 2 and located outside the first rubber sealing ring 9. A second rubber sealing ring 11 is disposed in the second annular groove 10. The outer surface of one side of the second rubber sealing ring 11 contacts the lower end surface of the first flange 1.

[0021] The second rubber sealing ring 11 can seal the gap between the first flange 1 and the second flange 2 again on the basis of the first rubber sealing ring 9, thereby improving the sealing effect and preventing leakage when the first rubber sealing ring 9 is damaged.

[0022] Specifically, a rubber sealing gasket 12 is provided on the upper end surface of the second flange 2, and the upper end surface of the rubber sealing gasket 12 contacts the lower end surface of the first flange 1;

[0023] The rubber sealing gasket 12 is bonded to the upper end surface of the second flange 2 to prevent external liquid from flowing between the first flange 1 and the second flange 2 and causing corrosion to the end surfaces of the first flange 1 and the second flange 2 that are close to each other.

[0024] Working principle: First, the staff inserts the screw 6 into the through hole 5 to bring the first flange 1 and the second flange 2 close to each other. At this time, the nut 7 is threadedly connected to one end of the screw 6 to fix the first flange 1 and the second flange 2 to each other. At this time, the outer surface of one side of the first rubber sealing ring 9 contacts one end face of the second flange 2, which can play a sealing role. At the same time, the outer surface of one side of the second rubber sealing ring 11 contacts one end face of the first flange 1, and the gap between the first flange 1 and the second flange 2 can be sealed again on the basis of the first rubber sealing ring 9, which can improve the sealing effect. At the same time, the rubber sealing gasket 12 can seal the gap between the first flange 1 and the second flange 2, which can prevent external liquid from flowing between the first flange 1 and the second flange 2, causing corrosion to the end faces of the first flange 1 and the second flange 2 that are close to each other, bringing convenience to people.
