The saturated refrigerant liquid under the condensing pressure in the condenser or the accumulator is throttled to the evaporation pressure and the evaporating temperature, and the refrigerant flow into the evaporator is adjusted according to the change of the refrigeration load.
     The throttle mechanism general manual throttle valve, thermostatic expansion valve, capillary, floating ball valve, capillary does not have a regulatory function, and the three throttle valve can also adjust the flow into the evaporator of the refrigeration unit, in order to adapt to the change of the cooling load, so as to achieve the purpose of refrigeration.
     Manual throttle is the most old-fashioned throttle valve. Mostly used in ammonia refrigeration equipment, manually adjust the valve orifice flow area to change the amount of liquid to the evaporator. Usually in the industrial chiller freon refrigeration system, the manual throttle valve as a spare valve installed in the bypass pipe, while the use of automatic throttling structure maintenance.
     Float control valve is based on changes in the level of flow control valve, throttle pressure and control the role of liquid level. The utility model relates to an automatic regulating throttle valve, which is used for automatically adjusting the liquid supply quantity of an evaporator, a gas-liquid separator and an intermediate cooler with a free surface. At present, it is mainly used in ammonia refrigeration equipment.
     Thermal expansion valve with the evaporator outlet refrigerant temperature changes, through the role of temperature sensing mechanism, automatic control valve opening to control the flow of refrigerant. The thermal expansion valve is mainly composed of a valve body, a temperature sensing bag and a capillary tube, and the utility model is suitable for the evaporator with no free liquid surface, such as a dry evaporator, a snake tube type evaporator and a snake pipe type intercooler. Is one of the most commonly used throttling mechanism.
