TECHNICAL FIELD
[0001] The present application relates to the technical field of refrigeration expansion valves, in particular to a novel refrigeration expansion valve with flow regulation. BACKGROUND
[0002] Expansion valves, also known as throttling valves, are valves that reduce the pressure of a fluid flowing through them by locally narrowing the flow cross-section and thereby respectively effecting a volume increase or expansion. In air conditioning systems, especially in motor vehicles, such expansion valves reduce the pressure of the refrigerant, which usually enters the expansion valve as a nearly boiling liquid. It thus undergoes an isenthalpic change of state, since the refrigerant releases pressure as it passes through the expansion valve (the pressure drops, for example, from 10 bar to 1 bar, while the temperature of the liquid drops). The purpose of the expansion in the valve is that the liquid reaches the evaporator with a lower degree of superheat (still in liquid form). The refrigerant then reaches the evaporator, in which the evaporation process of the liquid fraction of the refrigerant absorbs heat from the surroundings and thereby evaporates. The fluid or air flowing through the evaporator (heat exchanger) is thereby cooled.
[0003] The existing refrigeration valve, in the operation process, because the refrigerant is cooled or heated by circulation to complete the refrigeration cycle operation, so that the water content in the refrigerant and the water carried by the parts in the system are easily mixed in the refrigerant. During the operation of the entire refrigeration system, the compressor sucks the refrigerant, and then generates heat or heat phenomenon, but in the case of too much water in the refrigerant, the "liquid hammer" situation is easy to occur, which increases the probability of damage to the pressure machine. At the same time, too much water will also cause the pipe to freeze during the refrigeration process, causing the pipe to be blocked. The existing expansion valve does not have a mechanism for separating water and refrigerant, reducing the practicability of the existing expansion valve. Therefore, we propose a novel refrigeration expansion valve with flow regulation. SUMMARY

If the pressure is small at this time, it proves that the amount of analysis water discharged into the water storage pipe 308 is small, so that the electromagnet 328 and the electromagnet 329 are electrified to perform backwashing operation on the filter screen 331. If the analysis water continues to accumulate, the pressure received by the pressure sensor 324 increases, proving that the expansion valve causes the analysis water to decrease due to the blockage of the filter screen 331. Conversely, if the pressure continues to be low, it proves that the water content in the refrigerant is reduced due to the analysis of the expansion valve, so that the user can maintain the expansion valve, thereby improving the maintenance efficiency of the user and the practicability of the expansion valve.
