Description

Flange connection components

technical field

The invention relates to a flange connection assembly.

Background technique

Flange is also called flange flange or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. The flange connections in the prior art are all made by punching holes between two oppositely arranged flanges, and after passing through the two oppositely arranged flanges through bolts, nuts are used to fix the bolts, and then the two flanged together.

Such an arrangement is time-consuming and labor-intensive no matter when it is fixed or disassembled, and the bolted connection is easily vibrated and becomes loose, thereby reducing the connection strength and sealing performance of the flange.

Contents of the invention

In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a flange connection assembly with simple structure, firm connection and convenient assembly and disassembly.

In order to solve the above problems, the technical scheme adopted in the present invention is as follows:

A flange connection assembly, including an upper flange and a lower flange connected to each other, a plurality of positioning grooves are evenly distributed on the end surface of the upper flange, and a plurality of positioning grooves corresponding to the positioning grooves are arranged on the end surface of the lower flange. The positioning column; also includes an elastic ring sleeved on the outside of the upper flange and the lower flange, the elastic ring is provided with a gap, and the two ends of the gap are provided with connecting blocks, and the two connecting blocks are fastened The upper end of the elastic ring is provided with a cover plate, and the lower end is provided with a bottom plate directly below the cover plate. The cover plate, the elastic ring and the bottom plate are connected to form a space for accommodating the upper flange and the lower flange. Snap slot.

Further, a rubber sealing layer is provided in the clamping groove.

Further, the fastener includes a bolt and a nut sleeved on the bolt, and the two connecting blocks are provided with connecting holes for installing the bolt.

Further, an elastic pressing block sleeved on the bolt is arranged between the two connecting blocks, and one end of the elastic pressing block fits on the side surfaces of the upper flange and the lower flange.

Further, the thickness of the elastic pressing block is consistent with the width of the elastic ring.

Compared with the prior art, the beneficial effect of the present invention is that: when installing the flange, align the positioning column on the lower flange with the positioning groove on the upper flange and insert it to achieve preliminary positioning, and then insert the sleeve on the elastic ring On the outside of the upper flange and the lower flange, install the upper flange and the lower flange in the clamping groove, and then tighten the fasteners on the connecting block to make the gap smaller, so that the elastic ring will hold the upper flange It is firmly connected with the lower flange, the structure is simple, and the connection is firm. When disassembling, only the elastic ring is removed, and the upper flange and the lower flange are separated, which is convenient for disassembly and assembly.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2, a flange connection assembly includes an upper flange 1 and a lower flange 2 connected to each other, a plurality of positioning grooves 3 are evenly distributed on the end surface of the upper flange 1, and the lower flange 2 A plurality of positioning columns 4 corresponding to the positioning slots 3 are provided on the end face of the upper flange 1 and an elastic ring 5 sleeved on the outer side of the upper flange 1 and the lower flange 2, and the elastic ring 5 is provided with a gap 6 , and both ends of the gap are provided with connecting blocks 7, and the two connecting blocks 7 are connected by fasteners; the upper end of the elastic ring 5 is provided with a cover plate 8, and the lower end is provided with a bottom plate 9 directly below the cover plate 8 , the vertical distance between the bottom surface of the cover plate and the upper surface of the base plate is equal to the sum of the thicknesses of the upper flange and the lower flange, and the cover plate 8, the elastic ring 5 and the base plate 9 are connected to form an upper flange 1 And the clamping groove of the lower flange 2, the rubber sealing layer 10 is arranged in the clamping groove, the sealing performance of the upper flange and the lower flange can be improved through the rubber sealing layer 10, and at the same time, the elastic ring is more compactly connected to the upper flange. side of flange and lower flange.

In order to facilitate the operation of the fastener, the fastener includes a bolt 11 and a nut 12 sleeved on the bolt 11 , and the two connecting blocks 7 are provided with connecting holes for installing the bolt 11 .

In order to improve the tightness and connection firmness of the upper flange 1 and the lower flange 2, an elastic compression block 13 sleeved on the bolt 11 is arranged between the two connection blocks 7, and one end of the elastic compression block 13 is attached to the Closed on the sides of the upper flange 1 and the lower flange 2, the thickness of the elastic pressing block 13 is consistent with the width of the elastic ring 5.

Those skilled in the art can make various other corresponding changes and deformations according to the above-described technical solutions and concepts, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
