Abstract
The utility model discloses a kind of piping flange, comprise convex flange body (1) and female flange body (4), convex flange body (1) comprises Moving plate (1-1) and quiet dish (1-2), and Moving plate (1-1) and quiet dish (1-2) are assembled by seam (1-3); Described convex flange body (1) and female flange body (4) are provided with attachment hole (2) and receiving hole (3), described convex flange body (1) there is annular bead (5), described female flange body (4) is provided with the circular groove (6) coordinated with it, and circular groove (6) end face is provided with seal groove (7).The utility model can be applied to vibration, impact, high pressure operating mode, and the tightness that long-term maintenance is good, and structure simple optimizing.Moving plate (1-1) adjustment flexibly, the problem that when avoiding installation, attachment hole (2) misaligns.Joint stress between flange body and birdsmouth (3) is less, can save the vertebra neck of general welding neckflange, simplified structure.
Description
Technical field
The utility model belongs to flange technical field, relates to a kind of non-Newtonian fluid conveyance conduit adpting flange.
Background technique
At present, in colliery, near coal-mine, power plant, in the projects such as the gasification of coal slime Cemented filling, combustion system, Coal Chemical Industry thin grey Cemented filling, combustion system, sludge pipe transporting system, the method of extensive this advanced person of employing Cemented filling non-Newtonian fluid, piping flange connects with its easy-disassembling-assembling advantage, is widely used in the connection of the pressure piping of above-mentioned project.Flange is in high pressure operating mode for a long time, and pipeline operationally shock and vibration is large, easily there is leakage failure in flange connections, airtight quality is difficult to ensure.Under the effect of shock and vibration, all can there is creep in various degree in flange, bolt, pad, pad discontinuity, thus cause leakage failure.
Model utility content
For above-mentioned technical problem, it is blue that the purpose of this utility model is to be provided in a kind of conveying non-Newtonian fluid tube method.This piping flange can be applied to vibration, impact, high pressure operating mode, and the tightness that long-term maintenance is good.
To achieve these goals, the utility model adopts following technological scheme.
A kind of piping flange, comprise convex flange body and female flange body, convex flange body comprises Moving plate and quiet dish, and Moving plate and quiet dish are assembled by seam; Described convex flange body and female flange body are provided with attachment hole and receiving hole, and described convex flange body has annular bead, and described concave panel flange body is provided with the circular groove coordinated with it, and circular groove end face is provided with seal groove.This piping flange can be applied to vibration, impact, high pressure operating mode, and the tightness that long-term maintenance is good.
Described seal groove passes through seal with O ring.
The beneficial effects of the utility model are: piping flange of the present utility model can be applied to vibration, impact, high pressure operating mode, and the tightness that long-term maintenance is good, and structure simple optimizing.Moving plate can adjust flexibly, the problem that when avoiding installation, attachment hole misaligns.It is secondary that annular bead on flange body and circular groove form fitted seal, and the gasket seal causing the change of Axial stress in bolt to reduce because vibrating, impacting and cause under avoiding condition of high voltage lost efficacy.Joint stress between flange body and birdsmouth is less, can save the vertebra neck of general welding neckflange, simplified structure.
Certainly, implement arbitrary product of the present utility model might not need to reach above-described all advantages simultaneously.

In figure: 1, convex flange body; 1-1, Moving plate; 1-2, quiet dish; 1-3, seam; 2, attachment hole; 3, receiving hole; 4, female flange body; 5, annular bead; 6, circular groove; 7 seal grooves; 8, O shape circle.
Embodiment
In order to better understand the utility model, below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As shown in Figure 1, a kind of piping flange, it comprises convex flange body 1 and female flange body 4, and convex flange body 1 is made up of Moving plate 1-1 and quiet dish 1-2, and Moving plate 1-1 and quiet dish 1-2 is assembled by seam 1-3.
Described convex flange body 1 and female flange body 4 are all provided with attachment hole 2 and birdsmouth 3, and birdsmouth 3 is for being connected with pipeline.
Described convex flange body 1 is provided with annular bead 5, and described female flange body 4 is provided with the circular groove 6 mated with annular bead 5.Circular groove 6 end face is provided with seal groove 7.When being interconnected, annular bead 5 and circular groove 6 are formed and coordinate, and annular bead 5 and seal groove 7 are installed O shape circle 8 and formed sealing surface.
The sealing principle of described sealing surface is, annular bead 5 and circular groove 6 form matching pair, reduce because of vibration, impact and cause bolt, the weakening of pad power.
Adopt O shape circle 8 sealing, after O shape circle 8 distortion and annular bead 5 coordinate, the effect of sealing can be played.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
Claims (2)
1. a piping flange, comprises convex flange body (1) and female flange body (4), it is characterized in that, convex flange body (1) comprises Moving plate (1-1) and quiet dish (1-2), and Moving plate (1-1) and quiet dish (1-2) are assembled by seam (1-3); Described convex flange body (1) and female flange body (4) are provided with attachment hole (2) and receiving hole (3), described convex flange body (1) there is annular bead (5), described female flange body (4) is provided with the circular groove (6) coordinated with it, and circular groove (6) end face is provided with seal groove (7).
