Description
Technical field
The utility model relates to fiberglass sealed applied technical field, particularly a kind of one side groove round rubber circle seal glass steel flange.
Background technique
Steel flange adopts convex surface (RF) or plane (FF) to add the Placement of plain cushion sealing substantially, be attached thereto the glass fiber reinforced plastic flange connecing, due to Young's modulus low (only have steel 1/10), adopt face-flange, under the effect of bolt pretightening more, yielding, be difficult to guarantee virtual contact width and the decrement of pad, when nominal diameter is greater than DN600, when pressure surpasses 1.0MPa, this sealing means, the ratio of seepage obviously increases.
In U.S. ASME standard, although the Placement of small-bore flange dual-cavity sealing is provided, can solve the connection sealing problem between glass fiber reinforced plastic flange, but cannot solve the sealing problem that is connected between glass fiber reinforced plastic flange and other material flange, and groove is dovetail groove, larger for heavy caliber glass fiber reinforced plastic flange difficulty of processing.
Model utility content
The utility model proposes a kind of one side groove round rubber circle seal glass steel flange, it is simple in structure, is easy to machine shaping, and good sealing effect.The technological scheme that the utility model adopts is specifically achieved in that
The utility model provides a kind of one side groove round rubber circle seal glass steel flange, it comprises capping, seating plane and rubber ring, on described seating plane, there is semicircular groove, described rubber ring is positioned at described groove, described seating plane is glass steel material, the described upper capping contacting with rubber ring is plane structure or circular convex platform structure, described upper capping and described seating plane compress described rubber ring and realize sealing, and the diameter of described groove is more than or equal to the cross-sectional diameter of described rubber ring.
Preferably, described one side groove is semi-circular recesses.
Preferably, described rubber ring is round rubber circle, and its cross section is circular.
Preferably, described upper capping and described seating plane compress described rubber ring, and its decrement is between 30%-45%.
Preferably, the contact width after described upper capping and described rubber ring compression is greater than the cross-sectional diameter of described rubber ring.
One side groove ring seal glass steel flange of the present utility model, it is simple in structure, is easy to machine shaping, and good sealing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the seating plane in the one side groove round rubber circle seal glass steel flange of the utility model specific embodiment.
Fig. 2 is the overall structure schematic diagram of the one side groove round rubber circle seal glass steel flange of the utility model specific embodiment.
Fig. 3 is the structural representation of the rubber ring in the one side groove round rubber circle seal glass steel flange of the utility model specific embodiment.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, it will be more clear making above-mentioned and other object of the present utility model, Characteristics and advantages.In whole accompanying drawings, identical reference character is indicated identical part.Deliberately do not draw in proportion accompanying drawing, focus on illustrating purport of the present utility model.
Fig. 1 is the structural representation of the seating plane in the one side groove round rubber circle seal glass steel flange of the utility model specific embodiment.Fig. 2 is the overall structure schematic diagram of the one side groove round rubber circle seal glass steel flange of the utility model specific embodiment.Fig. 3 is the structural representation of the rubber ring in the one side groove round rubber circle seal glass steel flange of the utility model specific embodiment.
In conjunction with Fig. 1 to Fig. 3, one side groove round rubber circle seal glass steel flange of the present utility model, it comprises capping 20, seating plane 10 and rubber ring 30, upper capping 20 is plane near a side of seating plane 10, on seating plane 10, there is semi-circular recesses 11, rubber ring 30 is positioned at groove 11, seating plane 10 is glass steel material, the side that rubber ring 30 is adjacent with upper capping 20 is plane structure or circular convex platform structure, upper capping 20 compresses the rear realization sealing of rubber ring 30 with seating plane 10, and the diameter of groove 11 is more than or equal to the cross-sectional diameter of rubber ring 30.
As shown in Figure 2, in the utility model specific embodiment, the cross section of rubber ring 30 is circular, and as shown in Figure 3, whole rubber ring 30 is round rubber circle.In the utility model specific embodiment, upper capping 20 compresses after rubber ring 30 with seating plane 10, and its decrement is between 30%-45%.Preferably, the diameter of groove 11 is greater than the cross-sectional diameter of rubber ring 30.
The utility model adopts one side groove sealing plane flange, is not limited in above-mentioned specific embodiment, and flange can be the flange of any material of plane (FF) or convex surface (RF).Sealing means of the present utility model, is easy to guarantee decrement, and for the glass fiber reinforced plastic flange of heavy caliber and high pressure, sealing effect is better.
In the utility model, adopt semicircular groove, facilitate the processing of heavy caliber glass fiber reinforced plastic flange.Adopt the sealing of round rubber circle, for guaranteeing sealing effect, should make the decrement of cushion rubber between 30%～45%, the contact width after rubber ring compression should be greater than the cross-sectional diameter of round rubber circle.The diameter of semi-circular groove should be more than or equal to the cross-sectional diameter of round rubber circle.
The decrement of round rubber circle is calculated as follows:
In formula:
The decrement of α-round rubber seal ring, %
The cross section diameter of Φ 1-round rubber seal ring, unit is mm
The radius of R-semi-circular recesses, unit is mm
Prepsetting gap between X-flange facing, unit is mm
After rubber ring compression, contact width is calculated as follows:
In formula:
Contact width after the compression of b-round rubber seal ring, unit is mm
The cross section diameter of Φ 1-round rubber seal ring, unit is mm
The radius of R-semi-circular recesses, unit is mm
Prepsetting gap between X-flange facing, unit is mm
One side groove round rubber circle seal glass steel flange of the present utility model, it is simple in structure, is easy to machine shaping, and good sealing effect.The utility model can effectively solve heavy caliber glass fibre reinforced plastics face-flange because being out of shape the problem of the effective decrement deficiency of sealing gasket causing greatly, in addition, the utility model can guarantee the contact width after rubber ring compression, easy for installation, to heavy caliber, high pressure glass fibre reinforced plastics face-flange, good sealing effect.
