Description
Technical field
The invention belongs to mechanical field, and in particular to be a kind of prevent leakage supporting flange.
Background technology
Flange is widely used in every field as the important component in mechanical field, particularly in pipeline field,
Using especially extensively, in pipeline field, the application of flange is mainly used in the docking of pipeline, existing flange more using pipeline with
The form that ring flange is welded causes pipeline to be linked together with pipeline, and such flange can not be applied to some Special Rings
Border, some existing indivedual flanges use the flange with pipe joint to carry out pipeline and docked with pipeline, but it often produces docking
Imprecision, phenomena such as producing gas leakage, oil leak, leak, and most of flanges are docked using through hole, but in process,
Easily producing the through hole of the flange after processing can not match, and cause flange to be scrapped, during use is connected, easily because welding
The reasons such as deformation cause flange not dock accurately, or even docking is not firm enough, is broken in use, causes to endanger
Danger.
The content of the invention
In order to solve the above technical problems, a kind of docking of present invention offer is accurate, firm, and good seal performance, processing side
Just supporting flange.
To achieve the above object, the technical solution adopted by the present invention is a kind of supporting flange of prevent leakage, including the
One ring flange and second flange disk, its structural feature are that first flange disk is provided with first annular raised and first annular groove,
First flange disk is provided with stopper slot, and stopper slot is in T-shape, and stopper slot is provided with several openings, the periphery of first flange disk
Several screwed holes are provided with, second flange disk is provided with the second annular protrusion and the second annular groove, the second annular protrusion and
The adaptation connection of one annular groove, the second annular groove are adapted to connection with first annular projection, and second flange disk is provided with limiting section,
Limiting section is adapted to connection with stopper slot, and the periphery of second flange disk is provided with second flange dish axle to identical extension, prolonged
Extending portion is provided with through hole.
As the preferred scheme of the present invention, sealing ring is equipped with first annular groove and the second annular groove.
As the preferred scheme of the present invention, the through hole of extension on second flange disk with the periphery of first flange disk
Screw thread bore dia it is identical.
As the preferred scheme of the present invention, the width of the limiting section on second flange disk is equal to spacing on first flange disk
A/F on groove.
As the preferred scheme of the present invention, the limiting section on second flange disk is several.
As the preferred scheme of the present invention, the extension on second flange disk is several, and several extensions are with second flange
Annular array is put centered on the axle of disk.
The beneficial effects of the invention are as follows：It is rational in infrastructure simple, it is firmly accurate and easy to process during docking, avoid plus
The shortcomings that work is troublesome, error is larger, and there is good sealing property, it can effectively prevent from revealing, it is cost-effective.
