The Working Principle of Thermostatic Temperature Control Valve

The thermostatic temperature control valve, as its name implies, is a kind of valve that keeps the temperature constant, while the general valve can only adjust the heating and cooling. During the bathing process, the water temperature will suddenly become cold or hot due to the rapid changes in pressure and temperature, which is difficult to adjust. A thermostatic temperature control valve can solve this problem. The following is the working principle of the thermostatic temperature control valve.


Ⅰ. Types of thermostatic temperature control valve


1. Bathing thermostatic temperature control valve


A high-sensitivity memory alloy spiral temperature sensor is installed at the constant temperature water outlet. The sensor's extension or contraction directly controls the inlet flow of cold and hot water, so that the outlet temperature always reaches the set temperature (25-55°C). If the single pipe of hot and cold water is cut off during the bathing process, the water can be automatically stopped instantly to prevent scalding and cold. The setting of the one-way valve at the inlet of cold and hot water effectively prevents the mutual stringing of cold and hot water and the cold water from flowing back to the solar water heater.


2. Radiator thermostatic temperature control valve


By controlling the heat exchanger, air conditioning unit, or other heating and cooling equipment, the primary heat (cold) inlet flow rate can be used to achieve the outlet temperature of the control equipment. When the load changes, adjust the flow rate by changing the valve opening to eliminate the influence of load fluctuations and restore the temperature to the set value.

 


Ⅱ. The working principle of the thermostatic temperature control valve


1. The thermostatic temperature control valve is composed of bellows filled with a special temperature-sensitive liquid. The balance between the temperature-sensitive liquid and saturated gas makes the controller adjust proportionally according to the air temperature.


2. When the indoor temperature rises, part of the temperature-sensitive liquid inside the bellows is converted into gas, causing the bellows to expand, pushing the valve stem to proportionally close the thermostatic temperature control valve.


3. When the indoor temperature drops, the bellows are contracted by the tension of the spring, and the valve stem opens up proportionally to the thermostatic temperature control valve.
