Technical field
The utility model is related to the pipe fitting field of sanitizing fluid industry, is specifically related to a kind of hygienic adapter flange.
Background technology
Flange has application widely in fluid industry, its easy installation and removal, can bear larger pressure.In breast
Product beverage industry, the material contacted with product is required for being sanitation-grade, and requires to meet state health standards, but conventional
Flange connector typically belongs to the design of non-hygiene type, and its corresponding plain cushion or wound gasket are also non-hygiene design；Sometimes
Under special operating mode, flange two ends need to use various sizes of pipeline, and now common flange and flange gasket are with regard to nothing
Method, which is met, to be required, it is understood that there may be clean dead angle or using the reducing taken up too much space, influence is installed and attractive in appearance, it is therefore desirable to
A kind of hygienic adapter flange.
Utility model content
The purpose of this utility model is that provides a kind of hygienic adapter flange to solve the above problems.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of hygienic adapter flange, including flange body, bolt hole, face-flange and reducing end extension, the flange
It is provided with above body in bolt hole, the flange body and is provided with the internal reducing conical surface, is set above the internal reducing conical surface
Reducing end extension is equipped with, the internal reducing conical surface side is provided with T-shaped sealing ring, and the flange body side is provided with flat
Face flange.
In said structure, the T-shaped sealing ring of food-grade is embedded in the flange body, the T-shaped sealing ring
Size has 15-20% elasticity, so compactness is very good, adds the face-flange of pairing to the T-shaped sealing ring top
The extruding in portion, forms hygienic and tight sealed environment, and the internal reducing conical surface realizes the reducing of nozzle sizes, big osculum
Two ends are identical with the line size of both sides respectively；Prolong at the reducing end that the internal reducing conical surface osculum end extends one section of 5mm
Stretch pipe, convenient welding, the small-bore pipeline welding of the flange body and the internal reducing conical surface, the planar process of pairing
The large diameter pipeline welding of the blue and described internal reducing conical surface, two panels flange tightens connection with bolt by the bolt hole, close
Front cover ensures sealing effectiveness, the final connection effect for realizing health by the T-shaped sealing ring.
In order to further improve the use function of hygienic adapter flange, the bolt hole is six, is evenly distributed on described
Around flange body.
In order to further improve the use function of hygienic adapter flange, the internal reducing conical surface, the big osculum difference of reducing
It is identical with the sanitary line bore being attached thereto；Inner conical surface is polished to 0.8um.
In order to further improve the use function of hygienic adapter flange, reducing end extension, length 5mm and will
The pipe diameter of connection is identical.
In order to further improve the use function of hygienic adapter flange, the T-shaped sealing ring, the EPDM of material food-grade or
Person NBR, retains 15-20% elastic compression size.
In order to further improve the use function of hygienic adapter flange, the flange body has the plane of a pairing
Flange.
Beneficial effect is：This flange can reach food-grade health mark, and can cleaning up without dead angle, reducing is accounted for
It is small with space, it is ensured that easy for installation.
