Description

Technical Field

[0001] The utility model relates to the technical field of connecting flanges, in particular to a bending-resistant pipeline connecting flange. Background Art

[0002] Flange, also called 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 make the two flanges tightly connected. Gaskets are used to seal between flanges. 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 for pipeline connection. At the ends of two pipes that need to be connected, a flange is installed on each. Threaded flanges can be used for low-pressure pipelines.

[0003] In the prior art, for some oil pipelines buried underground, when these pipelines are connected by flanges, the corresponding supporting force at their joints is relatively weak, and the weight of the covering above the pipelines applies a large bending moment to the pipelines, making the joints of the pipelines easy to bend or break under the action of the bending moment, thereby causing pipeline leakage, posing a great hidden danger in use, and therefore a bending-resistant pipeline connection flange is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a bending-resistant pipeline connecting flange, which solves the problems in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, positioning blocks are fixedly mounted on the surface of the first connecting pipe, and the number of the positioning blocks is two groups.

[0008] Preferably, positioning grooves are provided inside the second connecting pipe, and the number of the positioning grooves is two groups, and the positioning grooves and the positioning blocks are arranged correspondingly.

[0010] Preferably, first fixing bolts are connected between the first flange and the second flange, and the number of the first fixing bolts is multiple groups.

[0011] Preferably, an insertion rod is fixedly mounted on the surface of the first fixing hoop and the second fixing hoop, and the first insertion hole and the second insertion hole are arranged corresponding to the insertion rod.

[0012] Preferably, the internal threads of the second fixing hoop are provided with second fixing bolts, and the number of the second fixing bolts is two groups.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the bending-resistant pipe connecting flange, by inserting the mounting block into the mounting groove and squeezing the sealing ring, makes the connection more sealed, so that the insertion rod is inserted into the first socket and the second socket, and the second fixing bolt is rotated to fix the first fixing hoop and the second fixing hoop. The first fixing bolt is provided to fix the first flange and the second flange. The positioning block and the positioning groove and the first socket, the second socket and the insertion rod can share the pressure on the connection between the first flange and the second flange, thereby better playing an anti-bending role, avoiding breakage or bending at the connection, and achieving a better connection effect.
