The application of thermostatic valve:
Floor heating system of hot water should run at about 50 DEG C; and the radiator heating system in hot water at 80 degrees Celsius, the central heating system of thermal recovery in the radiator into the floor heating, the following solutions were put forward; if the district with the floor heating scheme can reduce the construction of the boiler room or heat exchange station to reduce operating costs, and supplies. The general floor heating using aluminum pipe and PPR composite pipe, it can be resistant to high temperature above 80 DEG water, but in life, certainly not as good as the water temperature below 60 DEG C long service life; the copper tube joint with the pipe expansion and contraction coefficient is different, after the high temperature run, leaking joints will be very serious problem, influence the promotion of the floor heating, and easy to cause the user property damage.
We are in practice good to solve the floor heating at low temperature (55 DEG C) operation problem, installing the heat collecting water separator on the floor before the cold and hot water automatic constant temperature mixing valve. Thermostatic valve with cold water and hot water two water inlet interface, a mixed water outlet, the mixed water outlet thermostatic valve, equipped with a thermal component, using the physical characteristics of the temperature sensing element, driving the mobile spool valve body, water inlet blocking or open the cold and hot water, open water and cold water in the block and when the temperature control knob to set a temperature, regardless of the cold and hot water inlet temperature, pressure changes, hot and cold water inlet and outlet proportion also will change automatically, so that the water temperature is always constant, its positive and negative values remained within plus or minus 2 degrees between the temperature control knob can be specified within the temperature range of 35 DEG C to 65 C set, thermostatic valve will automatically adjust the water temperature setting. Note: the water supply pipe temperature of -95 mixed water temperature of 60 DEG -80 DEG to 55 DEG C above: water pipe in the check valve is to ensure the circulation pump only from geothermal backwater, if water temperature is higher than the mixed water temperature, automatic thermostatic valve will automatically close the water inlet, the geothermal system automatically, the water return the temperature drop after high temperature water in a certain proportion in the energy saving effect is obvious.
The above contents are arranged according to the problems encountered in the actual work of the students, for reference, if there are problems, please communicate and correct them in time.
