Description
Technical field
This utility model relates to flange field, a kind of antiseep flange connector.
Background technology
Flange (Flange), again call orchid flange or bead.Flange is interconnective part between pipe and pipe, uses
Connection between pipe end；Also having the flange that the equipment that is used in is imported and exported, the connection between two equipment, such as reductor method
Blue.Flange joint or bump joint, refer to be connected with each other as one group of combined sealing structure by flange, pad and bolt three
Releasable connection.Pipe flange means the flange of pipe arrangement in plumbing installation, is used on equipment the import and export flange of the equipment that means.Method
Perforation on orchid, bolt makes two flanges be close to.Seal with liner between flange.Flange divide threaded (screwed connection) flange,
Welded flange and clip flange.Flange is all to use in pairs, and low pressure pipeline can use wire connection flange, four kilograms of pressure above
Use welded flange.Plus sealing gasket between two panels ring flange, then fasten with bolt.The flange thickness of different pressures is different,
The bolt that they use is the most different.Water pump and valve, when connecting with pipeline, the local of these equipment facilities, also make relatively
The flange shape answered, also referred to as Flange joint.Every union piece making at two planar perimeter to be connected with simultaneously closing,
The most referred to as " flange ".
In the producing continuously of modern industry flange by dielectric corrosion, wash away, temperature, pressure, the factor such as vibrations are affected, by
In the error of sealing surface processing dimension, the aging and installation of potted component fastens the reasons such as improper, can inevitably cause method
Blue seepage.If flange leakage problems can not be administered in time, under the washing away of medium, meeting makes seepage expand rapidly, causes material
Loss, the destruction of production environment, cause enterprise shut down stop production, cause huge economic loss.If poisonous and harmful, easily
Fire explosive dielectric leakage, it is also possible to cause personnel to be poisoned, the major accident such as fire explosion.
