ページを印刷するOperating Principle
The controlling element of the solar thermostatic
mixing valve is a temperature sensor that is fully
immersed in the mixed water outlet passage. As
it expands or contracts, the sensor continuously
establishes the correct proportion of hot and
cold water entering the valve. The flow is
regulated by a piston sliding in a cylinder
between the hot and
cold water passages.
Even when there are
pressure drops due to
the drawing off of hot or
cold water for other uses
or
variations
in
incoming temperature,
the mixer automatically
regulates the water flow
to obtain the required
temperature.
