Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-3, a high pressure butt welding resistant flange with fish scale wing face, including flange main part 1, one side integrated into one piece of flange main part 1 has fixed cover 2, the circumference outer wall welding of fixed cover 2 has a plurality of fish scale fins 3, through the design of a plurality of fish scale fins 3, can be when high pressure butt welding resistant flange uses, the protect function on its surface has been increased, in order to avoid the condition that the butt welding flange surface is easily received high pressure impact and is produced deformation, the life of butt welding flange has been prolonged, satisfy people's demand, circumference one side of fish scale fin 3 bonds and has first protection backing ring 4, circumference one side integrated into one side of first protection backing ring 4 has a plurality of lugs 5, through the design of first protection backing ring 4 and lug 5, impact strength to fixed cover 2 can further be buffered, the effectual impaired condition of fixed cover 2 that reduces.
In the utility model, the circumferential inner wall of the fixed sleeve 2 is coated with the wear-resistant coating 6, the wear-resistant coating 6 can protect the inner wall of the fixed sleeve 2, the second protection backing ring 7 is adhered to the circumferential outer side of the flange main body 1, and a plurality of mounting holes 8 are formed on one side of the flange main body 1.
