The high resistance of the temperature control valve is determined by the adjustment characteristics of the radiator. The design of the temperature control valve must be considered in order to avoid the situation of insufficient capital pressure.

Temperature control valve installation position

The radiator thermostatic valve is generally installed on the inlet pipe of each radiator or the main inlet inlet pipe of the household heating system. Especially for the built-in sensor, vertical installation is not recommended, because the thermal effect of the valve body and surface pipe may cause the wrong operation of the thermostat controller. It should be ensured that the sensor of the thermostatic valve can sense the temperature of the circulating air in the city and must not be used by the curtain box. Covered by a heating cover.

In order to reduce investment, it is proposed to install only one temperature control valve on the indoor system (one heating system).

Normally, a thermostatic valve should be installed on each set of radiators (ie each room). In order to reduce investment, it is proposed to install only one temperature control valve on the indoor system (one heating system). The following is the first analysis of the thermal characteristics of the single-tube system, that is, the flow and room temperature changes, and pointed out the installation method of the temperature control valve.

The single-tube indoor system only has a thermostatic valve in the end room. Under the design external temperature, if the actual flow rate is less than the design flow rate (relative flow rate is less than 1), the upper layer heat and the lower layer cold phenomenon occur. Where the actual flow rate is greater than the design flow rate (relative flow rate is greater than 1.0), the upper layer cold and lower layer heat occur. Situation.
