▎ 摘　　要

NOVELTY - Diffuser mechanism of non-welding structure comprises a pipe component (20) that closely supports the sleeve on the spool (12) of the hull (10) and has a corrosion-resistant coating layer (25) on its surface, and a diffusion component supporting a wing pieces inside the sleeve and having a corrosion-resistant coating layer on the surface. The pipe component is coupled to the seawater valve (15) through flange formed at one end of the sleeve. The coating layers are formed of graphene with anti-corrosion properties. USE - The diffuser mechanism of non-welding structure is useful in seawater discharge channel. ADVANTAGE - The diffuser mechanism of non-welding structure: is easy to install; has long durability. DESCRIPTION OF DRAWING(S) - The drawing shows a installation state of diffuser mechanism of non-welding structure.
