Hitachi screw chiller thermal expansion valve G7D01428A R407C
Thermal expansion valve is an important automatic control component of refrigeration system, which can be divided into external balance type and internal balance type according to different balance modes, the utility model uses the temperature change of the temperature sensing packet as a signal to adjust the opening of the valve, changes the refrigerant flow rate, and makes the refrigerant of medium temperature and high pressure become the wet steam of low temperature and low pressure through its throttling, the refrigerant then absorbs heat in the evaporator to achieve the cooling effect.
The function of thermal expansion valve throttling depressurization will condense the high-temperature and high-pressure refrigerant after the condenser throttling depressurization, become easy to evaporate the low-temperature and low-pressure vapor-liquid mixture, into the evaporator evaporation, absorption of external heat; The thermostatic expansion valve can adjust the refrigerant flow into the evaporator automatically according to the temperature signal of the temperature sensing package to adapt to the needs of changing refrigeration load; Maintain a certain degree of superheat, prevent liquid hammer and abnormal superheat thermal expansion valve through flow regulation to make evaporator has a certain degree of superheat, to ensure the effective use of the evaporator total volume, at the same time, it can control the superheat in a certain range and prevent the abnormal superheat phenomenon. 2. The composition and working principle of the thermal expansion valve the thermal expansion valve is mainly composed of the induction mechanism, the executive mechanism, the adjustment mechanism and the valve body. When the temperature of the temperature sensing packet decreases, the opening of the valve decreases, and the refrigerant flow decreases proportionally, while when the temperature of the temperature sensing packet increases, the opening of the valve increases, and the refrigerant flow increases proportionally.
