Description
Technical field
The present invention relates to the sealing member of pipe joint, a kind of energy is suitable for the flange gasket structure of multiple pressure rating.
Background technology
The rubber flange gasket that the aqueduct of current domestic flange-interface is used has FF type, IBC type, C/D type, E/F type
Four kinds of patterns, wherein using more is IBC type.IBC type is full plastic structure, has flange production simple, easy for installation, by extensively
Model is applied.
IBC type flange gasket, is mainly used in the sealing between flanged pipe and flanged pipe, flanged pipe and valve or pipe fitting；Due to
The needs installed or use require to strengthen for the resistance to compression (intrinsic pressure or negative pressure) of flange gasket, want for different situations pressure (PN value)
Flange gasket parameter request under asking is different.
As Figure 1-Figure 2, due to the ring flange external diameter 71 of existing flanged pipe different pressures grade, bolt circle diameter (B.C.D.) 73 and
Diameter of bolt hole 74, therefore it is required that flange gasket external diameter is the most different；As by the DN400 spheroidal graphite cast-iron flange of ISO7005 standard production
Pipe, it is desirable to by the supporting flange gasket of ISO7483 standard, the flange gasket external diameter of PN10 is that the flange gasket external diameter of 489mm, PN16 is
The flange gasket external diameter of 495mm, PN25 be the flange gasket external diameter of 514mm, PN40 be 546mm.
And as the bore 70 of these 4 kinds of pressure rating lower flange pipes, thus flange gasket bore is the same, and require thickness
Spend too, but manufacturer have to be equipped with the mould of four grades, according to user's different designs demand, production, stock one
Plant the product of four kinds of models of specification.Use unit also to want the product of stock's four kinds of models of a kind of specification with standby simultaneously.So give
Produce and use and bring bigger inconvenience.
Summary of the invention
It is an object of the invention to for problem above, it is provided that a kind of energy is suitable for the flange gasket structure of multiple pressure rating, adopts
With a flange gasket common flange pipe PN10 and the pressure seal request of ratings above, the most same type product meets multiple method
Blue seal of tube requirement, saves manufacturing cost, convenient transhipment and stock, brings great convenience to use.
For realizing object above, the technical solution used in the present invention is: a kind of energy is suitable for the flange gasket of multiple pressure rating
Structure, it is loop configuration, is provided with the extension (901) extended laterally on loop configuration external diameter.
Further, described extension (901) is T-shaped platform structure.
Further, the hypotenuse of T stage is that radially extending of loop configuration is smoothly transitted into outermost end.
Further, described extension (901) is more piece stepped T-shaped platform structure,
Further, the hypotenuse of T stage is that stepped platform connects composition.
Further, extension (901) section thickness is consistent with loop configuration integral thickness.
Further, extension (901) section thickness is inconsistent with loop configuration integral thickness.
Further, described extension (901) is provided with multiple around the external diameter of loop configuration.
Further, described extension (901) is provided with 2 around the external diameter of loop configuration, and the two is at a distance of becoming certain
Angular displacement, preferential arrangement in 90 °.
Further, described extension (901) is around the external diameter of loop configuration towards unanimously.
Beneficial effects of the present invention: the invention provides a kind of energy and be suitable for the flange gasket structure of multiple pressure rating, uses
One flange gasket common flange pipe PN10 and the pressure seal request of ratings above, the most same type product meets multiple flange
Seal of tube requirement, saves manufacturing cost, convenient transhipment and stock, brings great convenience to use.
1, use present configuration, make the gasket width of original PN10 now can meet PN40 grade or greater degree simultaneously
Pressure.
2, manufacturing cost is saved, convenient transhipment and stock, bring great convenience to use.
