Abstract
The invention discloses a combined flange. The combined flange comprises a plurality of single flanges which are used for fixing a device, wherein a plurality of bolt holes are formed in the surface of each single flange; the two adjacent single flanges are connected by a fastener; the fasteners and the single flanges are integrated; a plurality of circular holes are formed in the surface of each fastener and used for well fixing the device. The combined flange provided by the invention has the characteristics of convenience for connection and use, simple structure and the like, and can bear high pressure.
Description
Technical field
The present invention relates to a kind of combined flange, particularly a kind of combined flange that is used on the machinery equipment.
Background technique
Flange (Flange) is flange plate or flange disk again.Flange is to make pipe and the interconnective part of pipe, is connected in pipe end; The flange that also has the equipment that is used in to import and export is used for two connections between the equipment, like the speed reducer flange.Flange connects or flanged joint, is meant by flange, pad and bolt three to interconnect the releasable connection as one group of combined sealing structure that piping flange means the flange that pipe arrangement is used in the tube equipment, is used in the import and export flange of the equipment that means on the equipment.Perforation on the flange, bolt are close to two flanges.Seal with liner between flange.Flange branch be threaded (screwed connection) flange and welded flange and clip flange.
Flange connects (flange joint) and is made up of a pair of flange, a pad and several bolt and nuts; Pad is placed between two flange seals, and behind the fastening nut, the specific pressure on the gasket surface produces distortion after reaching certain numerical value; And fill up uneven place on the sealing surface, make to connect and tightly do not leak.It is a kind of releasable connection that flange connects.Can be divided into vessel flange and pipe flange by the parts that connected; Press the structural type branch, integral (type) flange, lap joint flange and screwed flange are arranged.Common integral (type) flange has welded flange and welding neckflange.The rigidity of welded flange is relatively poor, is applicable to the occasion of pressure p≤4MPa; Welding neckflange is claimed hubbed flange again, and rigidity is bigger, is not suitable for the higher occasion of pressure and temp.The pattern of flange facing has three kinds: the plane sealing surface is applicable to the occasion that pressure is not high, medium is nontoxic; Male-female seal contact face is applicable to the occasion that pressure is high slightly; Tongue and groove seal contact face is applicable to inflammable, explosive, poisonous medium and the stronger occasion of pressure.
Summary of the invention
The object of the present invention is to provide a kind of combined flange, have and connect easy to usely, simple in structure, can bear bigger characteristics such as pressure.
For solving the problems of the technologies described above; The present invention adopts following technological scheme: a kind of combined flange, said combined flange comprise that several are used for fixing the single flange of device, and the surface of said single flange is provided with several bolts hole; Said adjacent single flange connects through fastening piece; Said fastening piece and said single flange are one, and the surface of said fastening piece is provided with several circular holes, is used for better fixing device.
In preferred embodiment of the present invention, the number of said single flange is 3.
In preferred embodiment of the present invention, the surperficial bolt hole number of said single flange is 6.
In preferred embodiment of the present invention, the surperficial circular hole number of said fastening piece is 6.
A kind of combined flange of the present invention has and connects easy to usely, simple in structure, can bear bigger characteristics such as pressure.
Description of drawings
Fig. 1 is a combined flange arrangement schematic representation in the present invention's one preferred embodiment;
Each assembly and reference character thereof are respectively among the figure: 1, single flange, 2, fastening piece, 3, bolt hole, 4, circular hole.
Embodiment
Below only be the general introduction of technological scheme of the present invention, understand technological means of the present invention, and can implement, below technological scheme of the present invention is further described with a preferred embodiment and accompanying drawing according to the content of specification in order can more to know.
Consult Fig. 1, this a kind of combined flange, said combined flange comprise that several are used for fixing the single flange 1 of device; The surface of said single flange 1 is provided with several bolts hole 3; Said adjacent single flange 1 connects through fastening piece 2, and said fastening piece 2 is an one with said single flange 1, and the surface of said fastening piece 2 is provided with several circular holes 4; Be used for better fixing device; The number of said single flange is 3, and the surperficial bolt hole number of said single flange is 6, and the surperficial circular hole number of said fastening piece is 6.Flange is fixed on the flange plate through being welded to connect a pipeline, pipe fitting or equipment, adds flange gasket, with bolton together, has accomplished connection, and flange portions is enclosed within on the flange.Flange plate adopts low-grade material, and pipe parts is used the material the same with pipeline, reaches the purpose of saving material; Each adjacent single flange is connected to each other through fastening piece, so just help combining closely of single flange and fastening piece, and fastening piece is processed with stainless steel; So just can bear very big pressure; Make the better fixing device of flange, flange neck height is lower, and rigidity, the bearing capacity of flange increased.Compare with welding neckflange, the welding job amount is big, and the welding rod consumption is high, is unable to undergo HTHP and alternating bending and temperature fluctuation; Make flange long service life etc. like this, calculation of price is reasonable, smooth surface, and acid-fast alkali-proof is high temperature resistant; Beautiful shape, the texture performance is strong, a kind of combined flange of the present invention; It is easy to use, simple in structure to have connection, can bear bigger characteristics such as pressure.
Embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
Claims (4)
1. combined flange; It is characterized in that: said combined flange comprises that several are used for fixing the single flange of device; The surface of said single flange is provided with several bolts hole, and said adjacent single flange connects through fastening piece, and said fastening piece and said single flange are one; The surface of said fastening piece is provided with several circular holes, is used for better fixing device.
2. combined flange according to claim 1 is characterized in that: the number of said single flange is 3.
3. combined flange according to claim 1 is characterized in that: the surperficial bolt hole number of said single flange is 6.
