Description

Split flange

Technical Field

The utility model relates to a pipe fitting, in particular to a split flange.

Background

The flange is a part of the connection between shafts, and is used for the connection between pipe ends, and also is useful for the connection between two devices, such as a speed reducer flange, on an inlet and an outlet of the device. The flange connection or the flange joint refers to detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange refers to a flange for a piping in a pipeline device, and is used on equipment to refer to an inlet and outlet flange of the equipment. The flanges are provided with holes, and the bolts are matched with nuts to enable the two flanges to be fastened and connected.

Because the fastened parts are closely contacted for a long time, under the action of environmental factors such as thermal expansion and cold contraction deformation of materials, aging corrosion of surfaces and influence of severe environments, the phenomenon of clamping and even dead between the two flanges is extremely easy to cause. In addition, the existing flange does not consider the later disassembly operation in the design process, and does not have a corresponding disassembly structure, so that the later disassembly of the flange is extremely difficult.

Disclosure of Invention

The utility model aims to provide a split flange which is simple in structure and convenient to disassemble, so that the later maintenance cost is reduced.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides a split type flange, includes two butt joint, sets up respectively in the left portion flange and the right part flange of two butt joint and connect the multiunit locking subassembly of left portion flange and right part flange, the left portion flange comprises two piece at least flange lamellar bodies and two piece at least flange lamellar bodies combination forms a ring shape, every all fixedly on the flange lamellar body be provided with the atress post that extends towards the right part flange, the extending direction of atress post is parallel with the axis of butt joint, after left portion flange and right part flange fastening, the atress post protrusion is in right part flange dorsad left portion flange side.

By adopting the technical scheme, after the left flange and the right flange are fastened under the action of the locking assembly, the stress column protrudes out of one side surface of the right flange, which is opposite to the left flange. When the left flange and the right flange are to be disassembled for maintenance, the locking assembly is disassembled firstly, then the force applied to one side of the left flange back to the right flange is applied by knocking the force-bearing column, and the convenient separation of the left flange and the right flange can be realized, so that the structure is simple, and the disassembly is convenient. And the interference phenomenon between the components caused by the lateral stress of the left flange in the process of knocking the stress column is avoided by arranging the left flange into a plurality of flange sheets, so that the simplicity and smoothness of the disassembling process are ensured.

Further provided is that: each stress column is arranged on one side surface of the flange sheet body, which faces to the right flange, and through holes for the stress columns to pass through are formed in the positions of the right flange, which correspond to the stress columns.

Through adopting above-mentioned technical scheme, the holistic small and exquisite, the compactness of flange is guaranteed to atress post cooperation through-hole, and when beating the atress post, acts on the atress direction on the atress post and the separation direction of flange lamellar body parallels to this structural strength who guarantees this design can realize the separation operation of flange lamellar body with minimum effort.

Further provided is that: the diameter of each stress column is gradually expanded along the direction from the right flange to the left flange, and an adjusting gap is formed between the stress column and the through hole after the left flange and the right flange are fastened.

Through adopting above-mentioned technical scheme, this kind of setting promotes the structural strength of atress post and with the area of contact of flange lamellar body, guarantees the structure steadiness to supply left portion flange and right portion flange both to have the space that can adjust the locking through the regulation clearance that forms, avoid causing structural interference.

Further provided is that: the stress column and the flange sheet body are integrally arranged, and a reinforcing block is integrally arranged on one side surface of each flange sheet body, facing away from the stress column, and is opposite to the stress column.

Through adopting above-mentioned technical scheme, the structural strength of flange lamellar body is further strengthened in the setting of boss, avoids appearing deformation.

Further provided is that: each group of locking components comprises a left hole body formed on the flange sheet body, a right hole body formed on the right flange, bolts penetrating through the left hole body and the right hole body and nuts in threaded connection with the bolts, and a limit groove for embedding the head of each bolt and communicating with the right hole body is formed in the position, opposite to one side surface of the left flange, of each right hole body.

Through adopting above-mentioned technical scheme, the setting of spacing groove further prescribes a limit to the mounted position of bolt, promotes assembly precision.

Further provided is that: the limiting groove is in rotary fit with the head of the bolt.

Through adopting above-mentioned technical scheme, this kind of setting accessible rotation bolt realizes locking operation, and the operation is more convenient.

In summary, the utility model has the following beneficial effects: the utility model has simple structure, convenient disassembly and low maintenance cost.
