20th century 40's radiator temperature control valve in Europe in the early 80s our country has begun to develop and radiator temperature control valve, into the 90's, the latter, with the heat metering technology to deepen and to meet the broad masses of the people room temperature for personalized requirements, a variety of domestic, import radiator temperature control valve products came into being, and many of its projects in China were used.
In the radiator heating the room temperature control can be used to control the radiator temperature control valve, but also better resistance characteristics can be manually controlled valves. Thermostatic radiator valve control of the use of the advantage of being able to control better the use of "free heat" to achieve the purpose of energy conservation, while avoiding the user to repeatedly adjust cumbersome.
1, the radiator temperature control valve as well as the breakdown of the working principle
Radiator temperature control valve and valve body from the temperature controller is composed of two parts. Principles of its users will spin the controller to the desired temperature setting temperature, when the room temperature exceeds the set temperature, the thermostat temperature controller inside the package (with sufficient medium temperature) thermal expansion, the volume increased to promote the stem, the valve clearance small, reducing the water flow radiator, so that at room temperature to reach set temperature. When the indoor temperature below the set temperature, the temperature by the cold shrink package size decreases, with the reset spring spool stem back to the valve opening, increasing the radiator water flow until the temperature reached for value.
1.1, temperature controller
Thermostat temperature controller package in accordance with its location can be divided into built-in temperature and package type FarEasTone. Package due to feelings of warm ambient air temperature is at the same time regulating valve action is a result of changes in temperature have a packet size, so the location of temperature package for the importance of the proper use of valves. In most cases, the need to adjust the radiator in this group are the indoor room temperature, the built package suitable temperature valves. In some specific cases, such as the radiator in this group was blocking the radiator cover, valve cover is located within, or close valves, there are other hot (cold) source, such as cooking, lighting and so strong , when its temperature is around the package of local feelings of heat, rather than the exact room temperature, suitable temperature controller type FarEasTone. In some special systems, such as the level of single-pipe systems, can only be installed in the first group of radiator valves, and the user again adjust the room temperature of the living room or master bedroom main-type temperature control may also have recourse to Far EasTone valves, temperature sensors will be placed in the living room or master bedroom collected regulate its temperature.
1.2, temperature control valve package can be in accordance with its temperature by a temperature sufficient to classify the different media can be broadly grouped into the following four categories:
1) steam temperature-inclusive
Wen package filled with the medium as a low boiling point liquid, when the outside temperature, some of vaporization of the liquid as a gas, temperature increase packet size to promote stem off a small valve opening, into the radiator into the reduced water flow, when the outside temperature decreases, some of liquefied gas and a liquid, temperature package size decreases, the valve opening increases, thereby increasing water flow radiator. Win this package in the regular medium temperature gas and liquid mixture, and the advantage of rapid time, but the temperature sealed package very strict, very little in the domestic application.
2) the liquid temperature-inclusive
Bag filled with warm temperature of the liquid medium for special, general, such as methanol or toluene. Larger packages such temperature, short time, the current in the wider domestic applications.
3) solid-state temperature-inclusive
Wen bag is filled with high expansion coefficient of solids, such as for the paraffin. Because of the relative gas and liquid solid heat (cold) the smaller volume, so its temperature moves slower, but the relative volume of small packet of liquid temperature in the domestic as well as some applications.
4) The metal plate
Its temperature controllers for temperature device with a special memory metal alloys, the metal due to热伸热伸drive valve action.
