Abstract
The utility model discloses a double sealing flange. The double sealing flange includes a flange body, a first bolt hole and sealing grooves. A second bolt hole is formed on the sealing groove. The flange is used cooperatively with another flange which shares the same structure. Between the sealing grooves is filled with sealing washers. The sealing grooves with bolt holes are added to the flange and an expansion bolt is used cooperatively; therefore, compared with the prior art, the sealing effect of the double sealing flange is substantially improved, the resource is saved, the environmental pollution is decreased and the service life is prolonged.
Description
Technical field
The utility model relates to the link of pipe fitting, the double seal flange plate that particularly uses on a kind of gas transportation facilities.
Background technique
In the 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 the 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 the flangeseal face, shortens its working life.
The model utility content
For the problem that above-mentioned prior art exists, the utility model 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 prolong working life.
To achieve these goals, the technical solution adopted in the utility model is: a kind of double seal flange plate, comprise flange plate body, the first bolt hole, also comprise sealed groove, have the second bolt hole on the described sealed groove, the flange plate that this flange plate is identical with another structure is used, and is filled by seal washer between the sealed groove.
Bolt connects between two flange plate, and employed bolt is EXPANSION ANCHOR BOLTS.
Seal washer matches with the shape of sealed groove.
Seal washer is the metallic graphite carbon spirotallic gasket.
The utility model has been 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, so not only saved resource, reduced environmental pollution, and prolonged the working life of flange plate.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the gasket structure schematic representation.
Among the figure: 1, flange plate body, 2, sealed groove, the 3, first bolt hole, the 4, second bolt hole, 5, seal washer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 with shown in Figure 2, this double seal flange plate, comprise flange plate body 1, the first bolt hole 3, also comprise sealed groove 2, have the second bolt hole 4 on the described sealed groove 2, the flange plate that this flange plate is identical with another structure is used, and is filled by seal washer 5 between the sealed groove 3.
Bolt connects between two flange plate, and employed bolt 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 the metallic graphite carbon spirotallic gasket, the second bolt hole 4 usefulness EXPANSION ANCHOR BOLTS connect into as a whole, it is welded on pipe joint with an end, the other end is welded on another pipe joint, and the first bolt hole 3 usefulness EXPANSION ANCHOR BOLTS on the last flange body 1 connect, and tighten, EXPANSION ANCHOR BOLTS expands, and sealing is finished.
