Product description
Mechanical accessories Expansion valve components
Throttling decompression and flow regulation Throttling decompression and flow regulation
Machinery Parts The function of the expansion valve in the cooling system is to throttle, reduce pressure and regulate the flow rate. it makes the medium temperature and high pressure liquid refrigerant become low temperature and low pressure wet steam through its throttling, and then absorb heat in the evaporator to achieve the cooling effect. The expansion valve controls the valve flow through the change of superheat at the end of the evaporator to prevent the underutilization of the evaporator area and the cylinder knocking phenomenon.
Electrical accessories Working principle of expansion valve
The expansion valve controls the opening of the valve by sensing the superheat of the gaseous refrigerant at the evaporator outlet through the temperature envelope. When the evaporator outlet superheat is large, Chassis Parts The opening of the expansion valve increases the refrigerant flow; On the contrary, when the superheat is small, the opening of the expansion valve decreases and the refrigerant flow decreases. This adjustment mechanism ensures that the refrigerant in the evaporator can be fully evaporated, thus achieving the best cooling effect.
Classification of expansion valves The expansion valve can be divided into internal balance type and external balance type. The temperature sensing bag and the refrigerant in the balance tube of the internal balanced expansion valve are mixed with the refrigerant at the evaporator outlet, while the temperature sensing bag and the balance tube of the external balanced expansion valve are directly connected with the evaporator outlet. In addition, expansion valves can be further classified according to their structure and use, such as F-type expansion valves.
