ksd301 temperature control switch temperature regulation principle

ksd301 temperature control switch only switch two states, it always switches back and forth between the two states. The temperature fluctuates greatly and the work is not smooth. Just like pressure control, temperature has a continuous proportional control method. In the cold winter in the north, every family will have a heater to keep warm. The capacity of heating is determined by the temperature of the water supplied by the heating center and the number of indoor radiators, but each family's living environment is different, so the indoor temperature requirements are different, for the elderly indoor temperature requirements are high, and young people are relatively low temperature requirements. But the water temperature in the radiator is no way to change according to the situation of each family. How to solve this problem? In fact, it is very simple, now the new radiator in the inlet pipe end are installed a regulating valve, through the regulating valve to control the indoor temperature to maintain in a certain required value.

In industrial production, there are many temperature regulators. Most of them have complex electronic circuits and thermistors to measure temperature, which work much more complicated than the regulation described here, and the regulation is much more effective.

Regulating valve how to control the indoor temperature? The regulator has a bellows filled with volatile liquid, bellows and pressure control in the same bellows, can change their length according to different pressure. The bellows are connected to the valve of the regulator. When the temperature in the room is very high, the volatile liquid in the bellows will be heated and expanded, which will make the bellows elongate. Push the valve to close the opening of the inlet pipe, so that the amount of water is smaller, so that the indoor temperature will drop. When the indoor temperature is lower, the volatile gas will shrink, the bellows will shorten, so that the inlet pipe valve opening increases, the water intake increases, and the indoor temperature rises. As long as each room is installed with this valve, each family can adjust the indoor temperature according to their own needs, which can make winter life more comfortable, but also can save energy. In fact, we often take the car also has the automatic temperature adjustment device, the car has a cooling system, so that the car engine will not overheat, so as not to affect the normal work. The cooling water temperature should be maintained at a temperature value, the cooling effect will be the best. So there is also a regulator in the cooling system to regulate the water temperature, which works on the same principle as the heating control valve mentioned above.
