Description
Technical field
The invention belongs to mechanical parts field, relate to a kind of flange.
Background technique
Flange is again flange plate or bead.Flange be make pipe and pipe or and the interconnective part of valve, be connected in pipe end.Perforation on flange, bolt is close to two flanges.Between flange, with liner, seal.Flange divides be threaded flange and welded flange and cutting ferrule flange.
Flange is the blue flange disk of call again.Flange is interconnective part between pipe and pipe, for the connection between pipe end; Also the flange that has the equipment that is used in to import and export, for the connection between two equipment, as speed reducer flange.Flange connects or flanged joint, refers to by flange, pad and bolt three and interconnects the releasable connection as one group of combined sealing structure.Piping flange means the flange that in tube equipment, pipe arrangement is used, and is used in the import and export flange that means equipment on equipment.Perforation on flange, bolt is close to two flanges.Between flange, with liner, seal.Flange divides the flange that is threaded, welded flange and clip flange.Flange is all to use in pairs, and low pressure pipeline can be used an acting flange, four kilograms of use welded flanges with upward pressure.Between two flange plate, add sealing gasket, then use bolton.The flange thickness of different pressures is different, and the bolt quantity that they use is also different.
It is exactly two pipelines, pipe fitting or equipment that flange connects, and is first fixed on separately on a flange plate, between two flange plate, adds flange gasket, by bolton together, has completed connection.Some pipe fittings and equipment have carried flange plate, are also to belong to flange to connect.It is the important Placement of pipeline construction that flange connects.Flange connects easy to use, can bear larger pressure.In industrial pipeline, the use that flange connects is very extensive, the foundation engineerings such as chemical industry, building, feedwater, draining, oil, weight are industrial, freezing, health, hot-water heating, fire-fighting, electric power, space flight, shipbuilding that it is widely used in.
Although flange application is extensive, but existing flanged connecting structure for to add flange gasket between two flange plate, then by two flange plate by bolton together, in installation and removal process, bolt needs installation or removal one by one, wastes time and energy.
Summary of the invention
The problems referred to above that the present invention need to solve are for above-mentioned the deficiencies in the prior art, and provide a kind of all very convenient in installation and removal process, and the good flange of tightness.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of flange, comprise the first flange plate and the second flange plate that cooperatively interact, the first flange plate and the second flange plate inside are all provided with axial pipeline, the first described flange plate is provided with connection ring portion near the pipeline end of junction surface, the diameter of described connection ring portion is greater than the diameter in the first flange coil pipe road, described connection ring portion is provided with internal thread, on the junction surface of the second described flange plate, along axial direction, be provided with the protruding rank of annulus portion, the protruding rank of described annulus portion is provided with the outside thread matching with the internal thread being connected in ring portion.
As the preferred technical solution of the present invention, the internal diameter of the protruding rank of described annulus portion is greater than the diameter of the pipeline of the second described flange plate.
As the preferred technical solution of the present invention, the diameter of the pipeline of the second flange plate described in the internal diameter of the protruding rank of described annulus portion equals.
As the preferred technical solution of the present invention, the protruding rank of described annulus portion width is vertically less than or equal to and connects ring portion width vertically.
As the preferred technical solution of the present invention, between described annulus protruding rank portion and connection ring portion, be lined with rubber pad.
As the preferred technical solution of the present invention, described annulus protruding rank portion and the second flange plate are wholely set.
As the preferred technical solution of the present invention, between the junction surface of the first flange plate and the junction surface of the second flange plate, be provided with flange gasket.
Compared with prior art, the invention has the beneficial effects as follows:
The first flange plate is provided with connection ring portion near the pipeline end of junction surface, the diameter of described connection ring portion is greater than the diameter in the first flange coil pipe road, described connection ring portion is provided with internal thread, on the junction surface of the second described flange plate, along axial direction, be provided with the protruding rank of annulus portion, the protruding rank of described annulus portion is provided with the outside thread matching with the internal thread being connected in ring portion, the first flange plate is threaded with the protruding rank of the annulus portion of the second flange plate by connecting ring portion, all very convenient during installation and removal.
Because the internal diameter of the protruding rank of annulus portion is greater than the diameter of the pipeline of the second described flange plate, so the hydrodynamic pressure of the protruding rank of annulus portion will be less than the hydrodynamic pressure in the first flange plate and the second flange plate pipeline, can increase the service life.
Because the internal diameter of the protruding rank of annulus portion equals the diameter of the pipeline of described the second flange plate, so the hydrodynamic pressure of the protruding rank of annulus portion will equal the hydrodynamic pressure in the first flange plate and the second flange plate pipeline, the damping of the protruding rank of annulus portion equates with the damping at pipeline place, can not affect the speed that fluid passes through.
Because the protruding rank of annulus portion width is vertically less than or equal to, connect ring portion width vertically, so the junction surface of the second flange plate just can be infinitely close with the junction surface of the first flange plate, improve the effect of sealing.
Between annulus protruding rank portion and connection ring portion, be lined with rubber pad, because rubber pad is built-in, and can be located completely, so can reach best sealing effect.
Because annulus protruding rank portion and the second flange plate are wholely set, thus structurally quite firm, and between annulus protruding rank portion and the second flange plate, there is not gap yet, sealing is good.
Between the junction surface of the junction surface of the first flange plate and the second flange plate, be provided with flange gasket, this is as second sealing defence line, can further improve sealing.
