Zusammenfassung:FIELD: various technological processes associated with cleaning and aeration of liquid media, water, petroleum products, weak alkalis and acids, tosol, hot bitumen and paraffin, trinitrotoluene, etc. SUBSTANCE: cup is made as an annular bush. Cup section is made in the form of a closed annular inner recess with filleted opposite-arranged transitions. At the ends, beginning from the boundary of the internal hole, concentric rows of knurlings are made, the boundary of the first one is made with a shoulder in the annular basic plane of inclined knurling, and the inclined flange near the other knurling coincides with the tapered surface of the end chamfer. The knurlings are arranged oppositely at the ends of the C-shaped shoulders of annular profile for flexible interaction with liquid medium at temperatures not exceeding 125 C. EFFECT: enhanced efficiency. 3 dwg
