Thermostatic valve

Thermostatic valve is the main heating system flow regulation regulating device, a heating system does not set the temperature control valve can not call it that heat metering systems. Thermostatic valve structure and principles, analysis thermostatic valve flow characteristics, combined with the radiator flow characteristics, while the introduction of safety gas valve authority concept, elaborated radiator thermal characteristics, under thermostatic valve flow characteristics and valve authority work together to ensure that the radiator system adjust effectiveness; and describes the thermostatic valve installation program; and finally elaborated thermostatic valve role in energy conservation.
Users control the indoor temperature is thermostatically controlled radiator valves to achieve. Radiator thermostatic control valve is a temperature controller, flow control valve and a pair of connectors, of which the core component is the thermostat sensor units, namely temperature package. Temperature sensor package can be generated by variations in ambient temperature volume changes to drive the gas stove valve spool is displaced, thereby adjusting the amount of water to change the radiator heat sink capacity. Thermostatic valve set temperature can be artificially adjusted according to set requirements for thermostatic valve will automatically control and adjust the radiator water to reach the control room temperature mesh.
Under certain degree of opening thermostatic valve flow and full flow ratio of G / Gmax called relative flow; thermostatic valve opening degree under a full travel itinerary and the ratio l called relative stroke. And the relative flow between the relative stroke relationship is called thermostatic valve flow characteristics, namely: G / Gmax = f (l). They showed a linear relationship between the characteristics of quick opening characteristic, such as several characteristics percentage of properties, characteristics parabolic curve.
Radiator, the water conservancy stability and thermal stresses from the scheduling point of view, the amount of heat flow on the relationship between the performance of a bunch of throwing curve, increase traffic G, the heat quantity Q gradually become saturated. To make the system has good regulation characteristics, easy to adopt equal percentage flow characteristic radiator valve to compensate for their non-linear effects (1).
