Abstract
The invention discloses a flange. A gasket is a wave-teeth combined gasket; a sealing flexible graphite spacer is arranged on a metal wave-teeth framework; graphite, an O-shaped ring and the metal wave-teeth framework are combined and mutually cooperate so that defects of single sealing can be overcome and better sealing effect can be achieved; a discharge hole is formed between a through hole and a joint pipe and the air in the gap between a sealing pad and the flange can be discharged so that the pressure can be reduced. The flange has the advantages of being simple in structure and good in sealing effect, and the wide market prospects are achieved.
Description
Technical field
The present invention relates to flange material territory, particularly a kind of flange.
Background technique
Flange, the again blue flange disk of call or bead.Flange is interconnective part between pipe and pipe, for the connection between pipe end; Also the flange that the equipment that is used in is imported and exported is had, for the connection between two equipment, as speed reducer flange.Flange joint or flanged joint, refer to and be interconnected releasable connection as one group of combined sealing structure by flange, pad and bolt three.Piping flange means the flange of pipe arrangement in tube equipment, is used in import and export flange equipment meaning equipment.Perforation on flange, bolt makes two flanges be close to.Liner containment is used between flange.Flange divide be threaded) flange, welded flange and clip flange.Flange is all use in pairs, and low pressure pipeline can use an acting flange, and four kilograms with the use welded flange of upward pressure.Add sealing gasket between two panels flange plate, then use bolton.The flange thickness of different pressures is different, and the bolt that they use is also different.Water pump and valve, when being connected with pipeline, the local of these equipment facilities, also makes corresponding flange shape, also referred to as Flange joint.Every union piece using bolt connection simultaneously to close at two planar perimeter, be generally all called " flange ", as the connection of ventilation duct, this class part can be called " flange type part ".But this connection is the local of an equipment, as the connection of flange and water pump, just bad water pump " flange type part ".More small-sized as valve etc., can cry " flange type part ".
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of flange, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technological scheme: a kind of flange, comprise flange body, the material of described flange body is carbon steel material, described flange comprises upper flange and lower flange, and described upper flange and lower flange are respectively arranged with mouthpiece, and described upper flange is connected by nuts and bolt with between lower flange, form cylindrical shape through hole between described upper flange and lower flange, the hole wall of described cylindrical shape through hole is provided with packing ring.
Preferably, described packing ring is set to wave tooth composite gasket circle.
Preferably, described wave tooth composite gasket circle is set to symplex structure, described wave tooth composite gasket circle comprises spacer ring body, O shape circle and metal wave tooth skeleton, described metal wave tooth skeleton is arranged on spacer ring body inside, described O shape circle has two, described O shape circle is connected with metal waveform skeleton, is filled with graphite between described O shape circle and metal waveform skeleton.
Preferably, describedly on metal wave tooth skeleton, sealed soft Graphite pad is provided with.
Preferably, discharge orifice is provided with between described cylindrical shape through hole and mouthpiece.
The beneficial effect of above technological scheme is adopted to be: a kind of flange of structure of the present invention, described packing ring is set to wave tooth composite gasket circle, describedly on metal wave tooth skeleton, be provided with sealed soft Graphite pad, graphite, O type circle and metal wave tooth skeleton three combinationally use, work in coordination to make up deficiency when it seals separately, thus reach better sealing effect, discharge orifice is provided with between described through hole and mouthpiece, the air in space between sealing gasket and flange can be discharged, thus minimizing pressure, it is simple that this flange has structure, the advantage of good sealing effect, there are wide market prospects.
