[Summary] This article provides a detailed explanation of the structure and working principle of thermostatic valves by Edson Valves. Structure of thermostatic valves: The thermostatic valve developed by our research team can be seen in its structural diagram; the external components include the housing, the lower-end connector, the octagonal connection nut, and the bottom valve connector. These components determine the overall shape of the device and serve to fix, connect, and support the internal parts. Fasteners determine and adjust the position of internal components, and their stable structure allows them to work in conjunction with other parts. The other internal components, from top to bottom, are the temperature sensor bulb, the Ti–Ni memory alloy spring assembly, the heat-insulating rubber rod, the plastic valve, the magnetic coupling mechanism, the support spring, and the support spring sleeve. The heat-insulating rubber rod and the plastic valve prevent heat flow from moving up and down within the device, thereby improving the accuracy of temperature control in the device. Below is the structural diagram of the temperature control valve (as shown in Figure 1). http://www.adxfamen.com/wp-content/uploads/2016/09/img_57e1e40bc14c9.png This temperature control valve uses a temperature-sensitive element to regulate the degree of opening of the valve. Its working principle is as follows: when the indoor temperature rises, the temperature-sensitive material expands, compressing the spring; this in turn moves the valve stem, causing the valve opening to become smaller. As a result, the amount of water flowing into the radiator decreases, which reduces the heat dissipation into the room and thus lowers the indoor temperature ； Conversely, the valve stem rebounds, the valve opening widens, the water flow increases, the heat supplied to the room rises, and the indoor temperature goes up. When there are other supplementary heat sources in the room (such as sunlight during the day, and other heat-generating devices), the valve automatically closes to reduce the water flow to the radiator, thereby achieving energy savings; it also helps to **improve the comfort level of the living space.
