Influence of valve authority on the regulation performance of thermostatic radiator valve of radiator

Determines the range that thermostatic radiator valve can proportionally adjust the heat output of radiators in different valve authority based on the thermal regulation performance of radiator, the flow regulation performance of thermostatic radiator valve and the combined thermal regulation performance of both radiator and thermostatic radiator valve. According to the actual variation of heating load in Tianjin, determines the minimum value of valve authority be 0.15 so as to ensure a favorable regulation performance of thermostatic radiator valve under the condition of 3% non-assurance rate.
