Abstract

A control arrangement for the temperature of the water drawn from a water pipe (5) contains a heat exchanger (3) lying with its primary side in series with a flow-adjusting valve (4) in a heated water circuit (2), and with its secondary side in the water pipe (5), a temperature sensor (6) lying in the water pipe (5) downstream of the heat exchanger (3), which temperature sensor converts the measured temperature into a pressure acting on a closure member of the flow-adjusting valve (4) against the force of a spring bearing against the housing (16) of the flow-adjusting valve (4), and a measuring orifice (7) in the water pipe (5). The flow-adjusting valve (4) contains a diaphragm between two chambers (10, 11), of which one (10) is connected to the high pressure side of the measuring orifice (7) and the other (11) is connected to the low pressure side of the measuring orifice (7). The deflection of the diaphragm (9) caused by the differential pressure at the measuring orifice (7) acts against the pressure of the temperature sensor (6) on the closure member of the flow-adjusting valve (4). To provide an energy-saving control arrangement, the diaphragm is rigidly connected to the closure member of the flow-adjusting valve (4) in the closing direction thereof, and its deflection in the opening direction of the flow-adjusting valve (4) is continually correlated with the pressure difference at the measuring orifice (7) and the difference between the spring force and the pressure force of the temperature sensor.
