Abstract

1353940 Reversing valves for heat exchangers KOBE STEEL Ltd 15 July 1971 33303/71 Headings F4P and F4K [Also in Division F2] A heat exchange system comprises a reversible heat exchanger A with a change-over valve C at its hot end and a check valve assembly B at its cold end. Change-over valve C, Fig. 3, comprises chambers M1, M2, M3 with nozzles 48-52, and a valve rod 43 with valve bodies 41, 42, the rod being reciprocable by piston 44 and a further piston 45 at the other end acting as a damping piston. Nozzles 50, 51 are connected to respective gas paths at the hot end of exchanger A, whilst nozzles 48, 49 communicate with a raw air supply. In the position of Fig. 3, waste gas flows from nozzle 50 to nozzle 52 and raw gas from nozzle 49 to nozzle 51, the nozzle 48 being isolated. Movement to the right results in raw air being supplied to nozzle 50 from nozzle 48, with waste gas flowing from nozzle 51 to nozzle 52 and nozzle 49 being isolated. The gas paths are thus reversed. The check valve assembly B, Fig. 4, comprises chambers R1, R2, R3 with nozzles 30-34 and check valve members 14 to 17 hinged to the valve body. From Fig. 6 it can be seen that raw air fed to nozzle 50 flows through to the cold end and enters nozzle 32 in assembly B, the pressure of the raw air maintaining valve member 14 closed but opening member 15 so that air flows out through nozzle 34. Waste gas returns via nozzles 31 and 33 member 17 being opened but member 16 being held closed by the greater pressure in chamber R2. Change-over of valve C leads to automatic change-over of assembly B, raw air then flowing from nozzle 33 to nozzle 34 and waste gas via nozzles 30 and 32. Flow control valves D 1 <SP>1</SP>, D 2 <SP>1</SP>, D 1 <SP>11</SP> control the flow rate in the various gas paths. The assembly B can have its valve members hinged so as to pivot outwardly to open rather than inwardly (Fig. 5, not shown). A single control valve may be used in place of valves D 1 <SP>1</SP> and D 1 <SP>11</SP> (Fig. 7, not shown) and several heat exchange systems such as that described may be used in parallel (Fig. 8, not shown).
