SPOOLS FOR HORIZONTAL SINGLE-PIPE HEATING SYSTEM (ALTERNATIVES) Russian patent published in 2008 - IPC F24D3/00 F24D19/00 

FIELD: construction, water supply.

SUBSTANCE: invention relates to the technology of water heating systems of buildings, connected to any heating source, and can be used in horizontal single-piped heating systems of buildings for any purpose and any number of floors. The technical outcome is: rational use of the parameters of the heating water due to the fact that the proposed construction of the spools provides for high coefficient of flow of the heat carrier. This allows for a more accurate determination of the heating surface of the heater and lowering hydraulic resistance of the spools. Besides that, the design provides for making spools without threaded connections on an industrial basis, which increases effectiveness of their operation. The spools for the horizontal single-piped heating system, consists of a part of the horizontal pipeline, supplying and taking away water, and is connected from one side to the heater. Reverse supply is done by a cavity in the horizontal part of the pipeline fro the side of the water flow, at an angle of 45° from the opposite side. Connection of the supply and reverse supply with part of the horizontal pipeline is done integrally. An alternative spools is also described.

EFFECT: increased effectiveness of operation of spools of water heating systems due to lowering of hydraulic resistance of the pipe and absence of threaded connections; optimisation of water flow.
