Abstract
Sealing flange pad belongs to Sealing, particularly relates to a kind of rubber seal flange gasket connected for piping flange interface.Feature offers at least ten road concentric sealing rings circles on the end face of described annular flat plate body both sides, and sealing ring is coaxial with the inner and outer surface of annular flat plate body; Sealing ring outside annular flat plate body on all establish the through hole that at least four sizes are identical, through hole and ring plate external surface non-intersect.Advantage is that pad end face offers sealing ring, therefore easy than the compressive strain of face-flange pad, and bolt clipping forcee reduces, good sealing effect, avoids occurring to leak security incident; Compression face increases, and the resistance to pressure of pad is strengthened; Registration, disposablely during installation is above just tightening flange plate clamping bolt, guarantees the sealing of the pipeline mouth of pipe, stability and endurance; Only need a people just can complete installation, convenient and swift, save manpower, increase work efficiency.
Description
Technical field
The utility model belongs to Sealing, particularly relates to a kind of rubber seal flange gasket connected for piping flange interface.
Background technique
Pipeline, when connecting, needs to install pad at joint flange place, ensures the sealing of pipeline junction, guarantee pipeline antileaking or gas leakage.Current pipeline flat mouth Flange joint, adopt plane smooth and with the rubber flange gasket sheet of mounting ear as Sealing.The defect existed be due to pipe joint in production, there will be nozzle sizes fluctuation or flanged surface out-of-flatness, the situation such as not parallel in installation process, use during the sealing of plane smooth rubber flange gasket sheet and can leak, cause security incident; Simultaneously because pipeline is generally horizontal positioned, and pipe joint upper flange gasket seal is vertically arranged, is subject to the easy sagging deflections of effect of gravity when mounted, causes difficulty to fitting operation compared with the flange gasket of large gauge.
Model utility content
In order to overcome the defect that prior art exists, the purpose of this utility model is to provide a kind of sealing flange pad, guarantees sealing effect when piping flange interface connects, and avoids occurring to leak security incident, reduces installation difficulty.
Sealing flange pad, comprises annular flat plate body, is characterized in offering at least ten road concentric sealing rings circles on the end face of described annular flat plate body both sides, and sealing ring is coaxial with the inner and outer surface of annular flat plate body; Annular flat plate body outside sealing ring all establishes the through hole that at least four sizes are identical, installs registration, through hole and ring plate external surface are non-intersect, increase the compression face of pad, enhancing resistance to pressure.
The utility model improves further, and the shape of described sealing ring is double wedge shape.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; Pad end face is offered sealing ring, therefore easy than the compressive strain of face-flange pad, bolt clipping forcee reduces, good sealing effect, avoids occurring to leak security incident; Compression face increases, and the resistance to pressure of pad is strengthened; Registration, disposablely during installation is above just tightening flange plate clamping bolt, guarantees the sealing of the pipeline mouth of pipe, stability and endurance; Only need a people just can complete installation, convenient and swift, save manpower, increase work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of sealing flange pad;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view Amplified image.
In figure: 1-annular flat plate body, 2-seal ring, 3-through hole.
Embodiment
Below in conjunction with embodiment, the utility model will be further described.
As can be seen from Fig. 1,2, sealing flange pad, comprises annular flat plate body 1, and the end face of described annular flat plate body both sides is offered ten road concentric sealing rings circles 2, and sealing ring is coaxial with the inner and outer surface of annular flat plate body; Annular flat plate body outside sealing ring all establishes the through hole 3 that eight sizes are identical, installs registration, through hole and ring plate external surface are non-intersect, increase the compression face of pad, enhancing resistance to pressure.
As seen from Figure 2, the shape sealing ring 2 is double wedge shape.
