Fluid connection flange

Abstract

The present invention relates to a fluid connection flange for firmly and tightly sealing the connection of a fluid pressure member, the fluid connection flange comprising: a solid first wall 21 forming a support surface 21a intended to be made against a mounting surface; a solid second wall 22 facing the first wall 21; at least one solid cylindrical spacer 23 extending perpendicularly between the first wall 21 and the second wall 22 to form a passage 24 intended to allow the passage of the shank 3a of the mounting member 3; a hollow filling portion 31 extending outside the spacer 23 between the first wall 21 and the second wall 22; and the first wall 21, the second wall 22, at least one spacer 23 and the filling portion 31 being jointly manufactured integrally by additive manufacturing techniques.

Claims

1. In a fluid connection flange, The aforementioned fluid connection flange is A solid first wall (21) that forms a support surface (21a) intended to come into contact with the mounting surface, A solid second wall (22) is provided so as to face the first wall (21), At least one solid cylindrical spacer (23) extending perpendicularly between the first wall (21) and the second wall (22) to form a passage (24) intended to allow the shank (3a) of the mounting member (3) to pass through, A hollow filling portion (31) extends outside the spacer (23) between the first wall (21) and the second wall (22), A fluid connection flange in which the first wall (21), the second wall (22), the at least one solid cylindrical spacer (23), and the filling portion (31) are jointly manufactured integrally by additive manufacturing technology.

2. The fluid connection flange according to claim 1, wherein the distance between the first wall (21) and the second wall (22) is constant, and the distance between the first wall (21) and the second wall (22) is at least 300%, preferably at least 500%, of the thickness of the first wall (21).

3. The fluid connection flange according to claim 1 or 2, wherein the filling portion (31) has a porous, columnar, or grid-like structure.

4. The fluid connection flange according to any one of claims 1 to 3, wherein the filling portion (31) occupies at least 50%, preferably at least 80%, more preferably at least 90% of the volume defined between the first wall (21) and the second wall (22) outside each spacer (23).

5. The fluid connection flange according to any one of claims 1 to 4, wherein the fluid connection flange comprises a notch (40) formed in the support surface (21a') and a seal (41) installed in the notch (40) formed in the support surface (21a').

6. The fluid connection flange according to claim 5, further comprising a solid reinforcing wall (27') extending perpendicularly to the second wall (22') toward the first wall (21'), wherein the reinforcing wall (27') extends to the notch (40) formed in the support surface (21a').

7. The fluid connection flange according to any one of claims 1 to 6, wherein the fluid connection flange comprises a solid closing wall (26) extending from the edge of the first wall (21) toward the second wall (22) along at least the edge of the first wall (21).

8. The fluid connection flange according to any one of claims 1 to 7, wherein the filling portion (31) opens outward along the outer edge of the first wall (21).

9. The fluid connection flange according to any one of claims 1 to 8, wherein the fluid connection flange comprises a solid working wall (10) that extends perpendicularly from the inner edge of the second wall (22) opposite to the first wall (21).

10. The fluid connection flange includes a solid transition wall (25) that extends diagonally between the second wall (22) and the working wall (10). A fluid connection flange according to any one of claims 1 to 9, wherein a second filling portion (32) is provided in a volume defined between the working wall (10), the transition wall (25), and the second wall (22).

11. The fluid connection flange (20) is made of metal, preferably selected from the group consisting of nickel-based alloys, aluminum-based alloys, titanium-based alloys, and steel, according to any one of claims 1 to 10.

12. A mechanical part comprising a fluid connection flange (20) according to any one of claims 1 to 11.
