the liquid inlet pipe main body is a U-shaped bent pipe, an outlet of the liquid inlet pipe is arranged at the upper part of the liquid storage device and close to the upper end cover, and the outlet of the liquid inlet pipe is arranged in a horizontal and upward direction;
when the liquid refrigerant containing a small amount of gas flows into the liquid reservoir from the inlet of the liquid inlet pipe, the flow direction of the liquid refrigerant is changed and the liquid refrigerant directly shoots the upper end cover of the liquid reservoir through the U-shaped bent pipe, so that the liquid refrigerant is ensured not to directly vertically shoot into the bottom of the liquid reservoir storing the liquid refrigerant, but naturally drops downwards due to the self gravity of the liquid refrigerant; because the drain pipe entry sets up in the reservoir bottom, and the liquid refrigerant of entering hits the upper end cover inner wall on, has reduceed the velocity of flow of liquid refrigerant, along with the velocity of flow slow down, under the effect of gravity, liquid is downward, gaseous upward movement, makes gas-liquid separation, has guaranteed completely like this that the refrigerant that flows from the reservoir is liquid refrigerant, has overcome the drawback of original structure, improves the performance and the stability of unit.
The lower edge of the upper end cover is downwards sleeved at the upper end of the cylinder body and is in welded sealing connection, and the upper edge of the lower end cover is upwards sleeved at the lower end of the cylinder body and is in welded sealing connection.
The outlet of the liquid inlet pipe is flush with the upper end of the cylinder.
The liquid outlet pipe inlet is obliquely arranged, and the included angle between the liquid outlet pipe inlet and the vertical direction is 40-50 degrees.
The included angle between the inlet of the liquid outlet pipe and the vertical direction is 45 degrees.
Compared with the prior art, the beneficial effects of the utility model are that: a novel turbulence-proof one-way flow liquid storage device is changed into a U-shaped bend through a liquid inlet pipe connecting pipe of a one-way valve liquid storage device, so that when a refrigerant flows into the liquid storage device, the refrigerant does not vertically downwards shoot into the bottom of the liquid storage device where the liquid refrigerant is stored, but the flowing direction of the refrigerant is changed to directly shoot onto an upper end cover of the liquid storage device. Thereby ensuring that the gaseous refrigerant is no longer injected into the bottom of the accumulator where the liquid refrigerant is stored, and the liquid refrigerant that just flowed into the accumulator naturally falls down due to gravity. Therefore, the refrigerant flowing out of the liquid accumulator is completely ensured to be liquid refrigerant, the defects of the original structure are overcome, and the performance and the stability of the unit are improved.
