Abstract
The invention discloses a dual-seal flange plate which comprises a flange plate body, first bolt holes and a sealing groove. Second bolt holes are formed in the sealing groove, the flange plate is used with another flange plate with the same structure, and a sealing washer is filled in a space between sealing grooves of the two flange plates. Compared with the prior art, the dual-seal flange plate has the advantages that the dual-seal flange plate is provided with the sealing groove with the bolt holes and is used with expansion bolts, so that sealing performance of the dual-seal flange plate can be obviously improved, resources can be saved, environmental pollution can be reduced, and the service life of the flange plate can be prolonged.
Description
Technical field
The present invention relates to the link of pipe fitting, the double seal flange plate particularly using on a kind of gas transportation facilities.
Background technique
In gas transportation facilities, flange plate is usually used in connecting tube equipment.Mostly common flangeseal face is plane shape at present, the two flange plate symmetries that are welded on pipeline place are installed together, because it bears barotropic fluid for a long time, the situation of revealing is more common, not only caused the waste of resource, the pollution of environment, and long-term leakage also can cause damage to flangeseal face, shortens its working life.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of flange plate, good seal performance, and the wasting of resources is few, and environmental pollution is little, and simple in structure, and extend working life.
To achieve these goals, the technical solution used in the present invention is: a kind of double seal flange plate, comprise flange plate body, the first bolt hole, also comprise sealed groove, on described sealed groove, have the second bolt hole, the flange plate that this flange plate is identical with another structure is used in conjunction with, and between sealed groove, by seal washer, is filled.
Between two flange plate, bolt connects, and the bolt using is EXPANSION ANCHOR BOLTS.
Seal washer matches with the shape of sealed groove.
Seal washer is metallic graphite carbon spirotallic gasket.
The present invention is because having increased the sealed groove that has bolt hole, and is equipped with the use of EXPANSION ANCHOR BOLTS, therefore compared with prior art, its sealability is significantly improved, therefore not only saved resource, reduced environmental pollution, and extended the working life of flange plate.
Accompanying drawing explanation
Fig. 1 is invention structural representation.
Fig. 2 is gasket structure schematic diagram.
In figure: 1, flange plate body, 2, sealed groove, the 3, first bolt hole, the 4, second bolt hole, 5, seal washer.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1 with shown in Fig. 2, this double seal flange plate, comprise flange plate body 1, the first bolt hole 3, also comprise sealed groove 2, on described sealed groove 2, have the second bolt hole 4, the flange plate that this flange plate is identical with another structure is used in conjunction with, and between sealed groove 3, by seal washer 5, is filled.
Between two flange plate, bolt connects, and the bolt using is EXPANSION ANCHOR BOLTS.
Seal washer 5 matches with the shape of sealed groove 2.
During enforcement, first two identical flangeseal grooves 2 of structure are embedded in to metallic graphite carbon spirotallic gasket, the second bolt hole 4 use EXPANSION ANCHOR BOLTS connect into as a whole, by one end, it is welded on pipe joint, the other end is welded on another pipe joint, and the first bolt hole 3 use EXPANSION ANCHOR BOLTS in last flange body 1 connect, and tighten, EXPANSION ANCHOR BOLTS expands, and sealing completes.
Claims (4)
