The connection structure for pipeline port with the special structure employs a plurality of optimized structure designs, is convenient to the energy saving manufacture and convenient use of the structure, and employs an integral casting shaping technique, thereby effectively increasing the integral structure intensity of the flange plate; the flange plate has the advantages of novel appearance structure, effective production and manufacture as well as quick mounting and use.
Description
Technical field
The utility model relates to a kind of linkage structure of pipe end.
Background technique
In the pipeline fluid engineering, utilize bolt and flange usually, will need interconnective pipe fitting to carry out Butt sealing.At present general linkage structure mainly contains two kinds of situations, and a kind of is based on fastening flange, and is often not enough or settle service condition abominable because of flange bolt hole precision in actual use, and causes the Butt sealing difficulty; Another kind is connection characteristics of utilizing flat mouthful of class pipe fitting, and flange is made split two-piece type bascule, often descends because of join strength or does not have corresponding optimal design profile, and limited to its application development.
The model utility content
Technical problem to be solved in the utility model is the linkage structure that a kind of pipe end is provided at problems of the prior art, its objective is by optimizing the configuration design of flange, reach the sealing effect that when guaranteeing join strength, also can realize.
The technical solution of the utility model provides a kind of linkage structure of pipe end, this linkage structure comprises pipeline, the end of pipeline is provided with flat mouthful of end face, the outer surface of pipeline is provided with spacing catch near the flat mouth of end face, the rotary flange sheet is set on the pipeline, and between flat mouthful of end face and spacing catch.
Described rotary flange sheet is the mass activity shaping structure, and an end face of rotary flange sheet is provided with groove, and groove can be located mutually with the cylindrical of flat mouthful of end face and be compressed.
Described rotary flange sheet is provided with the bolt hole of rectangular grooved.
One end face of described rotary flange sheet is provided with at least one loss of weight groove.
Described loss of weight groove and groove are positioned at the same end face of rotary flange sheet.
Described loss of weight groove is that trapezoidal loss of weight is optimized groove.
Described spacing catch is a rectangular.
Linkage structure with a kind of pipe end of above-mentioned special construction has the following advantages:
1, this connection main flange sheet has adopted multinomial optimized Structure Design, is convenient to the energy-conservation manufacturing and the convenient use of this structure.
2, adopt the cast inblock formation technique, thereby increased the overall construction intensity of flange plate effectively.
3, this flange plate has the form structure novelty, manufactures efficiently, installs and uses efficiently.

In Fig. 1-5,1: pipeline; 2: flat mouthful of end face; 3: spacing catch; 4: the rotary flange sheet; 5: groove; 6: bolt hole; 7: the loss of weight groove; 8: rubber gasket; 9: connecting bolt.
Embodiment
Shown in Figure 1 is a kind of linkage structure of pipe end.This linkage structure comprises pipeline 1, the end of pipeline 1 is provided with flat mouthful 2 of end face, the outer surface of pipeline 1 is provided with rectangular spacing catch 3 for flat mouthful 2 near end face, rotary flange sheet 4 is big gap and is set on the pipeline 1, and between flat mouthful 2 of end face and spacing catch 3, can between flat mouthful 2 of end face and spacing catch 3, do radially rotation and axial displacement.
Fig. 2 and the structural representation that Figure 3 shows that rotary flange sheet 4, rotary flange sheet 4 is the mass activity shaping structure, one end face of rotary flange sheet 4 is provided with groove 5, and it is about 2/3 of integral (type) flange thickness, and groove 5 can be located mutually to cooperate and be compressed with the cylindrical of the flat mouth 2 of end face; For ease of the location that interconnects of flange, the bolt hole 6 on the rotary flange sheet 4 is rectangular grooved design; For ease of the energy-conservation manufacturing of rotary flange sheet 4 with install and use, rotary flange sheet 4 is provided with eight trapezoidal loss of weight grooves 7, loss of weight groove 7 runs through the flange circumferential end surfaces, loss of weight groove 7 wide 1/3 of the end face of flange that are about, and loss of weight groove 7 and groove 5 are positioned at the same end face of rotary flange sheet 4.
Fig. 4 is the axial sectional view of spacing catch 3 in the utility model, and spacing catch 3 and end face can guarantee that rotary flange sheet 4 is in radially rotation and axial displacement between flat mouthful 1 of end face and spacing catch 3 on the external diameter of pipeline 1 for flat mouthful 1.
Fig. 5 is a working state figure of the present utility model.Two pipe end linkage structures are carried out relative displacement, insert rubber gasket 8 flat mouthful 2 of two pipeline end faces simultaneously, adjust the mutual alignment of the bolt hole 6 of rotary flange sheet 4, penetrate connecting bolt 9, the nut that is rotatably connected, the displacement to axial of drive activity turned flange sheet 4, the cylindrical that groove 5 and end face are flat mouthful 2 is located mutually and is compressed, make that rubber gasket 8 compresses distortion between the pipeline end face, thereby finish the Butt sealing of pipe fitting.
