Regulating valve for three affected temperatures - has cold hot and mixture temperature sensors coupled for alternative control

摘要

The temperature sensitive valve control arrangement is one in which the control valve setting is affected in dependence upon three different temperatures. The temperature probe for one of the mixing liquids links up with the probe for the resultant mixture for alternative control of one or the other. The three-way mixing valve (1) serves for cold liquid inlet (K) and warm liquid inlet (W) resulting in mixture (M) having resultant temperature probe (11). The warm liquid probe (26) is of bellows form coupled to a heating circuit (27), alternatively coupled to a source of supply (18, 19) to cut out, or switch in, another heating circuit (15) through a switching contact (20, 21, 22) arrangement. In this way control can be made in dependence upon outside, ambient, temperature.
