Abstract
The invention relates to the technical field of large-size mechanical parts, in particular to a large-size sealing flange. According to the technical scheme adopted by the invention, the large-size sealing flange comprises a flange main body with the diameter being 4.6 m and is characterized in that the center of the flange main body is a round hole with the diameter being 3 m; one end of the flange main body is provided with a first assembling end; a first sealing structure is arranged at the connecting position of the first assembling end and the flange main body; the other end of the flange main body is provided with a second assembling end; a second sealing structure is arranged at the connecting position of the second assembling end and the flange main body; and the flange main body is further provided with two positioning grooves which are distributed in a bilateral symmetry mode. The large-size sealing flange has the advantages that the installation process is reduced, and the installation efficiency is improved, so that installation of the large-size flange is more convenient, and the sealing performance is better.
Description
Technical field
The present invention relates to big machinery spare and accessory parts technical field, more particularly to a kind of large sealing flange.
Background technology
Flange (Flange) is called ring flange or bead.Flange is the part for making pipe be connected with each other with pipe, is connected to
Pipe end.Perforation on flange, bolt is close to two flanges.The all kinds of of flange much have the structure flanges of some standards, there is also
Some off-gauge flange parts, are selected according to the demand of different structure.
The special flange of a class can be used in some bulk transport engineerings, that is, large-sized flange.This kind of flange it is straight
Footpath is generally more than 2 meters.Sealing ring can be used when being attached using flange, the sealing after flange connection is guaranteed with this
Property, large-sized flange is no exception, needs also exist for installing sealing ring to guarantee its sealing.Due to the volume of large-sized flange it is big,
The installation of sealing ring during installation is also relatively bothered, and needs at least 2 people to be operated simultaneously；In addition, large-sized flange is in peace
It is difficult to be accurately positioned during dress, to installment work certain trouble is also brought.
The content of the invention
It is an object of the invention to provide a kind of large sealing flange, installation is made more on the basis of ensureing that installation effect is good
Plus it is convenient, required artificial less during installation, cost of labor is lower.Technical scheme is as follows：
A kind of large sealing flange, including a diameter of 4.6 meters of flange main body, it is characterised in that：The flange main body
Center is a diameter of 3 meters of circular hole, and one end of the flange main body is provided with the first assembling end, the first assembling end and the method
The junction of blue main body is provided with the first sealing structure；The other end of the flange main body is provided with the second assembling end, second dress
Second seals structure is provided with end with the link position of the flange main body；Two locating slots are additionally provided with the flange main body,
The locating slot is symmetrical distribution.
Further, the height at the first assembling end is 1/5th of the height at the second assembling end.
Further, six fixing holes are additionally provided with the flange main body, the fixing hole is evenly distributed on the flange
In main body.
Beneficial effects of the present invention：
The present invention reduces installation procedure, improves installation effectiveness, make large-sized flange more convenient when mounted, sealing is more
It is good.
Description of the drawings
Fig. 1 is the dimensional structure diagram of first direction of the present invention；
Fig. 2 is the dimensional structure diagram of second direction of the present invention；
Fig. 3 is the front schematic view of the present invention；
In figure：1st, flange main body, the 2, first assembling end, the 3, first sealing structure, the 4, second assembling end, the 5, second sealing knot
Structure, 6, locating slot, 7, fixing hole.
Specific embodiment
As shown in Figure 1 to Figure 3, a kind of large sealing flange, it is ensured that the sealing of large-sized flange, and avoid employing
Also flange uses cooperatively to reach sealing effectiveness the sealing ring of traditional approach, but directly arranges close on large-sized flange part
Seal structure, makes sealing structure be structure as a whole with large-sized flange, and installation steps raising work effect so can be saved when mounted
Rate, can also be to good sealing effectiveness.The present invention includes a diameter of 4.6 meters of flange main body 1, the flange main body 1
Center is a diameter of 3 meters of circular hole, can give connection after pipeline provide more conveying space.The one of the flange main body 1
End is provided with the first assembling end 2, and the first assembling end 2 connects the first segment pipe, it is linked together with the first segment pipe.Described
One assembling end 2 is provided with the first sealing structure 3 with the junction of the flange main body 1, is used to ensure that with tube fit after being connected
Sealing, it is thus also avoided that troublesome problem is installed using sealing ring.The other end of the flange main body 1 is provided with the second assembling end
4, the second assembling end 4 connects the pipeline of another side so as to link together with the pipeline of another side.It is described second assembling end 4 with
The link position of the flange main body 1 is provided with second seals structure 5, and second seals structure 5 is fixed with tube fit fixes it
Better tightness afterwards, installs more convenient.Two locating slots 6 are additionally provided with the flange main body 1, the locating slot 6 is left and right
It is symmetrical, it can first be carried out by pre-determined bit when fixed by symmetrical locating slot 6, the peace of flange is then carried out again
Dress, convenience when so may insure the accuracy installed and installing.
Preferably, the height at the first assembling end 2 is 1/5th of the height at the second assembling end 4, first
Assembling end 2 attachment force required when being connected with pipeline attachment force required when being connected with pipeline less than the second assembling end 4, therefore
They are arranged to into different height, experiment proves that the height at the first assembling end 2 is the five of the height at the second assembling end 4
When/mono-, effect is best.
Preferably, being additionally provided with six fixing holes 7 in the flange main body 1, the fixing hole 7 is evenly distributed on the method
In blue main body 1.Large sealing flange is fixed by six fixing holes 7, it is ensured that fixed firmness, connects it
The stability for connecing is more preferable.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, some improvement or replacement can also be made, these improve or replace
Should be regarded as protection scope of the present invention.
