ELBOW 90 DEGREES FOR A PIPE AIR TRANSPORT.

摘要

A sewing 90 degrees self-cleaning, which causes a low pressure drop and largely prevents the occurrence of angel hair, comprises a widening (2) and tubular asymmetric cross section of a plate of percussion (6) arranged on the outer side of the bend and a constriction (4) of the tubular and asymmetric transvrsale section towards the exit. The striker plate (6) forms an angle of about 55 degrees to 65 degrees with the flow inlet direction. The inside of the bend is formed by a tubular half-shell (3) of a quarter circle. Other surfaces are formed by filling segments (7) to give a closed cross section.
