Abstract

The utility model discloses a kind of modified model ultra high molecular polyethylene tubing centering flange, for connecting the multiple steel pipes being provided with liner tubing, described centering flange comprises the recessed flange and boss flange that cooperatively interact, described recessed flange is provided with groove, described boss flange is provided with the boss with fit depressions, liner tubing flange on adjacent two steel pipes extends between the fitting surface of the groove of recessed flange and the boss of boss flange, and on the flange of any one liner tubing, be provided with annular recess, in described annular recess, be provided with annular seal.Annular seal, after use annular seal, only need compress, not only ensure that the sealing of recessed flange and boss flange joint, also ensure that the quality of liner tubing simultaneously, make the longer service life of steel pipe by the utility model.After adopting annular seal simultaneously, there is the sealing barrier effect of annular seal, more can guarantee the sealability of pipeline.

Description

Modified model ultra high molecular polyethylene tubing centering flange
Technical field
The utility model relates to a kind of centering flange, more particularly, and particularly a kind of modified model ultra high molecular polyethylene tubing centering flange.
Background technique
In long distance ore pulp delivery duct, two kinds of Placements below general employing: time one, with bolts, each joint is a hidden leakage defect, capital is likely to environment, existing design connected system sealing forms sealing mainly through excess compression flange place frosting, and this just requires to require that the smooth thickness of the smooth surface of liner is even to the torque value of bolt is very high simultaneously; Under the pressure of high strength, bushing pipe flange root can produce distortion, can produce fracture when more serious, substantially can not use by secondary.Two, adopt the mode that is welded to connect to guarantee sealing, when fed sheet of a media has soda acid, or during the characteristic such as corrosion, even if weld ensure that the sealing of pipeline, but because of the acid and alkali corrosion for a long time to weld, also can produce leakage.Therefore, be necessary to design a kind of modified model ultra high molecular polyethylene tubing centering flange.
Model utility content
The purpose of this utility model is to provide a kind of and avoids bushing pipe flange root deformation and can ensure the modified model ultra high molecular polyethylene tubing centering flange of sealability.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of modified model ultra high molecular polyethylene tubing centering flange, for connecting the multiple steel pipes being provided with liner tubing, described centering flange comprises the recessed flange and boss flange that cooperatively interact, described recessed flange is provided with groove, described boss flange is provided with the boss with fit depressions, liner tubing flange on adjacent two steel pipes extends between the fitting surface of the groove of recessed flange and the boss of boss flange, and on the flange of any one liner tubing, be provided with annular recess, in described annular recess, be provided with annular seal.
Preferably, the groove of described recessed flange is provided with concave surface sawtooth, and the boss of described boss flange is provided with convex surface sawtooth, and the concave surface sawtooth of described recessed flange is corresponding with the convex surface sawtooth of boss flange.
Preferably, described recessed flange is connected by organizing bolt with between boss flange more.
Preferably, described annular seal is O RunddichtringO.
Compared with prior art, the utility model has the advantage of: the utility model is after use annular seal, only annular seal need be compressed, not only ensure that the sealing of recessed flange and boss flange joint, also ensure that the quality of liner tubing simultaneously, make the longer service life of steel pipe.After adopting annular seal simultaneously, there is the sealing barrier effect of annular seal, more can guarantee the sealability of pipeline.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of modified model ultra high molecular polyethylene tubing centering flange described in the utility model.
Fig. 2 is the stereogram of modified model ultra high molecular polyethylene tubing centering flange described in the utility model.
Description of reference numerals: 1, steel pipe, 2, liner tubing, 3, recessed flange, 4, boss flange, 5, bolt, 6, annular seal.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1 and Fig. 2, the utility model provides a kind of modified model ultra high molecular polyethylene tubing centering flange, for connecting the multiple steel pipes 1 being provided with liner tubing 2, described centering flange comprises the recessed flange 3 and boss flange 4 that cooperatively interact, recessed flange 3 is provided with groove, boss flange 4 is provided with the boss with fit depressions, liner tubing 2 flange on adjacent two steel pipes 1 extends between the fitting surface of the groove of recessed flange 3 and the boss of boss flange 4, and on the flange of any one liner tubing 2, be provided with annular recess, annular seal 6 is provided with in described annular recess.
Annular seal 6, after use annular seal 6, only need compress by the utility model, not only ensure that recessed flange 3 and the sealing of boss flange 4 joint, also ensure that the quality of liner tubing 2 simultaneously, make the longer service life of steel pipe 1.Due to the flange surface that this annular seal 6 mounting point is liner tubing 2, therefore, need to adopt on the surface of liner tubing 2 mode of grooving machine grooving to form annular recess, then annular seal 6 is installed in annular recess.After adopting annular seal simultaneously, there is the sealing barrier effect of annular seal, more can guarantee the sealability of pipeline.
In order to further improve installation capability, the utility model is provided with concave surface sawtooth on the groove of recessed flange 3, and the boss of boss flange 4 is provided with convex surface sawtooth, and the concave surface sawtooth of recessed flange 3 is corresponding with the convex surface sawtooth of boss flange 4.Convex surface sawtooth and concave surface sawtooth, when the flange surface contact with liner tubing 2, can allow liner tubing 2 be close to sawtooth, add frictional force, make it that striction phenomenon be less likely to occur.
Recessed flange 3 in the utility model is connected by organizing bolt 5 with between boss flange 4 more.
As preferably, described annular seal 6 is O RunddichtringO.
Although describe mode of execution of the present utility model by reference to the accompanying drawings; but patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection domain described by claim of the present utility model, all should within protection domain of the present utility model.
