Description

Technical Field

[0001] The utility model relates to the technical field of flanges, and more particularly to a connecting flange group for connecting multiple pipelines. Background Art

[0002] Flanges are parts that connect shafts to each other. They are mainly used to connect pipe ends. They are also used on equipment inlets and outlets to achieve the connection between two devices, forming a detachable connection with a combined sealing structure.

[0003] The existing flange connection is to fix two pipes on a flange plate respectively, and then fix the two flange plates together. However, when multiple pipes are connected in parallel, this method often causes problems such as multiple pipes not being parallel and bolt holes being misaligned, which brings great inconvenience to the installation work.

[0004] Therefore, how to provide a connecting flange group for connecting multiple pipelines to ensure parallel connection of multiple pipelines is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In view of this, the utility model provides a connecting flange group for connecting multiple pipelines, which ensures that multiple pipelines are connected in parallel.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A connecting flange group for connecting multiple pipelines comprises: two flange plates, on which a plurality of pipeline mounting holes matching the outer diameters of the pipelines are opened, a plurality of connecting holes are evenly opened in the circumferential direction of the flange plates corresponding to the pipeline mounting holes, the two flange plates are arranged opposite to each other and the corresponding connecting holes of the two flange plates are connected by a connecting piece.

[0008] Through the above technical scheme, the utility model provides a connecting flange group for connecting multiple pipes. Through the setting of multiple pipe mounting holes and connecting holes, it can ensure that multiple pipes are connected in parallel, effectively avoiding project delays caused by problems such as non-parallel pipes and misaligned bolt holes, and making the process of connecting multiple pipes more convenient and quick, ensuring the convenience and accuracy of pipe connection; the two flanges are tightly connected through the connecting piece.

[0009] Furthermore, the connecting member may be a bolt.

[0010] Furthermore, a sealing gasket is clamped between the plate surfaces of the two flanges. The sealing gasket can ensure the sealing performance of the connection between the two flanges.

[0011] Preferably, the flange is surrounded by a plurality of annular plates, two adjacent annular plates are integrally connected by a connecting plate, the central hole of the annular plate is a pipe mounting hole, and a plurality of connecting holes are evenly opened on the plate surface of the annular plate. The design of surrounding the plurality of annular plates and the plurality of circular plates can make the load more evenly distributed on the flange, reduce stress concentration, and thus increase the service life of the flange; and can increase the overall structural strength of the flange, so that it has better stability and durability when subjected to pressure, torque or vibration.

[0012] It can be seen from the above technical scheme that compared with the prior art, the utility model discloses a connecting flange group for connecting multiple pipes. Compared with the prior art, the utility model can ensure the parallel connection of multiple pipes through the setting of multiple pipe mounting holes and connecting holes, effectively avoiding project delays caused by problems such as non-parallel pipes and misaligned bolt holes, and making the connection process of multiple pipes more convenient and quick, ensuring the convenience and accuracy of pipe connection; the design of multiple circular plates surrounded by multiple annular plates can make the load more evenly distributed on the flange, reduce stress concentration, and thus increase the service life of the flange; and can increase the overall structural strength of the flange, so that it has better stability and durability when subjected to pressure, torque or vibration.
