Thermostatic valve

Do many people want to know what the working principle of the temperature control valve is?

The temperature control valve is composed of two parts: a valve and a temperature control element. The temperature control element includes special expanded paraffin wax and a red copper shell. At a specific phase transition temperature, the expansion stress of the expanded paraffin is a fixed value, which is far greater than the thrust required by the thermostatic valve. Then the working principle of the temperature control valve is that the expanded paraffin is sealed in the shell. When the temperature rises to the melting point of the paraffin, the volume expands and pushes the ejector rod. The slide valve that drives the temperature control valve is moved; when the temperature drops, the paraffin will contract when cold, and the valve will be reset under the action of the spring’s rebound.

The characteristics of the temperature control valve: significant thrust, the paraffin inside the element can reach more than 200 atmospheres when the wax expands, and the stroke temperature curve is linear. Therefore, the temperature control ability is strong, the components are rigid, the strength is high, and the long life.
