Abstract
The utility model discloses a blind flange, including circular shape chassis, a plurality of screws of circumference evenly distributed on the chassis, set up the through -hole in the middle of the chassis, the through -hole internal stability is equipped with the anticorrosive board of adaptation, anticorrosive board is made by the anti -corrosion material. The utility model aims at providing a blind flange that sealing performance is good, with low costs.
Description
Technical field
This utility model relates to flange field, is specifically related to a kind of blank flange.
Background technology
Blank flange is also referred to as blank flange, and rectification of name is called blind flange, is middle flange the most with holes, is a kind of flange
Type of attachment, for sealing pipe stopper.In industries such as oil, chemical industry, metallurgy, electric power, boats and ships and machineries, blank flange rises
Isolation, the effect of cut-out pipeline, be the same with end socket, pipe cap, welding plug role.It is a kind of that blank flange seals
Dismountable sealing device, and the sealing of end socket does not prepare to open again.Due to blank flange good seal performance, for needs
Completely isolated system, the most all as reliable isolating means.
Utility model content
The purpose of this utility model is to provide the blank flange of a kind of good seal performance, low cost.
To achieve these goals, the technical solution adopted in the utility model is: a kind of blank flange, including the circular end
Dish, on chassis, circumference is uniformly distributed some screws, it is characterised in that: offer through hole in the middle of described chassis, fixed in described through hole
Having the anticorrosive board of adaptation, described anticorrosive board is made up of anti-corrosion material.
This utility model is further arranged to, and described anticorrosive board is followed successively by the first polytetrafluoroethyl-ne fitted from the inside to the outside
Alkene layer, steel wire floor and the second polytetrafluoroethylene floor.
This utility model is further arranged to, and described steel wire floor is stainless steel material, and steel wire floor reticulates distribution.
This utility model is further arranged to, and described chassis also sets up a circle groove, described groove be positioned at screw and
Between anticorrosive board.
This utility model is further arranged to, and the cross section of described groove becomes to be flared out shape and arranges.
The beneficial effects of the utility model: blank flange provided by the utility model, by anticorrosive board and the periphery at center
Chassis composition, the blank flange being the most all made of stainless steel, its cost is lower, has again good corrosion resistance；With
Time chassis be provided with groove, groove is used for location and installation sealing gasket, makes sealing gasket be easily installed, and installation site is accurate, is allowed to
Sealing effectiveness is more preferable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Label implication in figure: 1-chassis；2-screw；3-through hole；4-anticorrosive board；41-the first polytetrafluoroethylene floor；42-steel
Silk layer；43-the second polytetrafluoroethylene floor；5-groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
Below with reference to Fig. 1, this utility model is illustrated.
A kind of blank flange, including circular chassis 1, on chassis 1, circumference is uniformly distributed some screws 2, in described chassis 1
Between offer through hole 3, the size of through hole 3, with to need the caliber sealed corresponding, is installed with adaptive anticorrosive board 4, institute in described through hole 3
State anticorrosive board 4 to be made up of anti-corrosion material, described anticorrosive board 4 be followed successively by from the inside to the outside fit the first polytetrafluoroethylene floor 41,
Steel wire floor 42 and the second polytetrafluoroethylene floor 43, described steel wire floor 42 is stainless steel material, and steel wire floor 42 reticulates distribution,.
Use the anticorrosive board 4 that above-mentioned material is formed so that it has corrosion-resistant, high intensity, good stability and use the longevity in use
The advantage that life is long, practicality is high.
Also set up a circle groove 5 on chassis 1, described groove 5 between screw 2 and anticorrosive board 4, described groove 5 cut
Face becomes to be flared out shape and arranges.Said structure is used to reach conveniently to install the purpose of sealing gasket, so the most permissible when assembling
Easily sealing gasket is installed and put in place；And being obliquely installed of groove 5 sidewall, then make, when installing sealing gasket, can pass through
The sidewall that the two tilts plays an effect guided, and achieves the centering of sealing gasket, location efficiently, is more convenient for close
Installation between packing and blank flange.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification, above-mentioned vacation
If these improve and modification also should be regarded as protection domain of the present utility model.
