Abstract:
1. Flow control in an accumulator tank or a boiler for a heating system for reducing the flow velocity of a liquid heating medium flowing into the accumulator tank or boiler, wherein the flow control ( 1 ) comprises an inner substantially tubular member ( 5 ) and an outer substantially cylindrical member ( 6 ) which defines a space ( 7 ) for accommodating at least a part ( 5 a ) of said inner tubular member, the inner tubular member ( 5 ) is at one end ( 5 c ) thereof configured with an inlet opening ( 8 ) for a liquid heating medium flowing into the accumulator tank ( 2 ) or boiler and at least one outlet opening ( 9 ) in a side wall thereof, a deflector means ( 10 ) is provided in the inner tubular member ( 5 ) at the outlet opening ( 9 ) for deflecting the flow of liquid heating medium out of the inner tubular member through said outlet opening, a perforated member ( 12 ) is provided on the inner tubular member ( 5 ) covering at least the outlet opening ( 9 ) such that the flow of liquid heating medium deflected through said outlet opening passes through perforations ( 13 ) in said perforated member, the outer cylindrical member ( 6 ) comprises a solid part ( 14 ) and a perforated part ( 15 ), and the outer cylindrical member ( 6 ) is positioned around the inner tubular member ( 5 ) such that the solid part ( 14 ) thereof is located substantially opposite to the outlet opening ( 9 ) in the inner tubular member for deflecting the flow of liquid heating medium from said inner tubular member towards the perforated part ( 15 ) of the outer cylindrical member and through perforations ( 16 ) therein into the interior ( 2 a , 2 b , 2 c ) of the accumulator tank ( 2 ) or boiler.
