Abstract

1420127 Mixing flowing liquids ADOLPH SAURER AG 3 Sept 1973 [5 Sept 1972] 41264/ 73 Heading B1C [Also in Division F1] A device for mixing and impelling heatexchange fluids comprises an impeller interposed between first and second chambers and having a suction side communicating with the first chamber and a pressure side communicating with the second chamber; an outlet communicating with the second chamber and a user; a pair of inlets for cooler or hotter heatexchange fluid, one communicating with the first chamber and the other with a third chamber; a pair of axially aligned apertures interconnecting the first and third chambers; and tubular baffle means shiftable axially in the apertures for increasing the effective cross section of one aperture while simultaneously decreasing that of the other, and vice versa. Cooled water is returned via an inlet 11 to a chamber 10 of a central heating pump, while hot water from the boiler is supplied via an inlet (21) to a chamber 16, both chambers communicating via a suction chamber 17 with the eye of the pump impeller 4, which discharges a mixture of the two streams of water to an outlet 8. The proportion of the two streams in the mixture is determined by a tubular valve 12 which is axially movable by means of a control rod 13 between the extreme position shown in which the annular passage A, from the chamber 10 to the chamber 17 is open to the maximum extent while the annular passage A 2 from the chamber 16 to the chamber 17 is completely closed and the other extreme position in which the passage A 1 is completely closed and the passage A 2 is open to the maximum extent. A sealing ring 20 is provided. The temperature of the mixture is sensed by a sensor 22 insulated at 25 from the pump housing and connected to an electronic control for the drive to the valve control rod 13.
