[0003] The existing patent (application number: CN202222610572.4) discloses a high-efficiency liquid separation device for Freon refrigeration. When the device realizes that Freon evenly passes through the capillary tubes into different branches of the heat exchange pipeline, the height of the capillary tubes needs to be the same. However, when the capillary tubes are damaged and need to be replaced, the height of the new capillary tubes needs to be adjusted to the same height as the other capillaries. High-precision adjustment is required, which makes the operation more troublesome and wastes a lot of time required for installation. Therefore, the utility model provides a Freon refrigeration liquid separation device. Utility Model Content

[0021] Reference Figure 1-5A Freon refrigeration liquid separation device comprises a cylinder 1, an upper end cap 2 is threadedly connected to the top of the cylinder 1, a lower end cap 3 is threadedly connected to the bottom of the cylinder 1, a liquid inlet pipe 4 is fixedly installed inside the lower end cap 3, a liquid separation umbrella cap 5 is fixedly installed on the surface of the liquid inlet pipe 4, a mounting hole 6 is penetrated at the bottom of the lower end cap 3, a capillary tube 7 is threadedly connected inside the mounting hole 6, a notch 8 is opened at the top of the capillary tube 7, a through hole 9 is penetrated on the inner wall of the capillary tube 7, and the notch 8 and the through hole 9 are arranged so that Freon can enter the capillary tube 7 more conveniently, a mounting plate 10 is fixedly installed on the surface of the lower end cap 3, a fixing plate 11 is fixedly installed on the top of the fixing plate 10, and a screw cap 5 is rotatably connected inside the fixing plate 11 Rod 12, a turntable 13 is fixedly installed on the surface of the screw rod 12, a moving block 14 is threadedly connected to the surface of the screw rod 12, the moving block 14 is L-shaped, and the moving block 14 is made of metal material. The setting of the moving block 14 made of metal material facilitates the moving block 14 to have a higher structural strength, thereby facilitating the moving block 14 to be more durable, and a guide rod 15 is slidably connected inside the moving block 14, the guide rod 15 is cylindrical, and the guide rod 15 is made of metal material. The setting of the guide rod 15 made of metal material facilitates the guide rod 15 to have a higher structural strength, thereby facilitating the guide rod 15 to be more durable, and also facilitates guiding the movement of the moving block 14 , avoiding the phenomenon of displacement when the moving block 14 moves, and the guide rod 15 is fixedly connected to the fixed plate 11, and the opposite surface of the moving block 14 is fixedly installed with a baffle 16, the number of baffles 16 is multiple, and the baffles 16 are symmetrically distributed. Through the arrangement of multiple symmetrically distributed baffles 16, it is convenient for the baffle 16 to better block all the capillaries 7. The number of capillaries 7 is multiple, and the multiple capillaries 7 are distributed in a circular array. The height of the top of each capillary 7 is the same, and the height of the top of the capillary 7 is the same as the height of the bottom of the baffle 16. In the Freon refrigeration liquid separation device, when a capillary 7 is damaged and needs to be replaced, the cylinder 1 and the capillary 7 are replaced. Remove it, rotate the turntable 13 to make the screw 12 rotate, so that the moving block 14 and the baffle 16 are close to each other to a suitable position along the guide rod 15, and then install the new capillary 7 into the mounting hole 6 from the bottom of the mounting hole 6 until the top of the new capillary 7 contacts the bottom surface of the baffle 16, and then rotate the turntable 13 in the opposite direction to move the baffles 16 away from each other to a suitable position, and finally install the cylinder 1 back on the lower head 3, thereby achieving the goal of replacing the capillary 7 more quickly. During installation, it is convenient to make the capillary 7 have the same height as other capillaries 7 by only making the top of the capillary 7 contact the bottom surface of the baffle 16, thereby reducing the time required for replacing the capillary 7.

[0022] When in use: connect the liquid inlet pipe 4 to the outlet of the expansion valve, connect the capillary tube 7 to each branch heat exchange pipeline of the refrigeration heat exchanger, and the Freon enters the cylinder 1 through the top of the liquid inlet pipe 4. Then the Freon will flow down evenly along the liquid separation cap 5 and fall into the capillary tube 7 at the same height, and then evenly enter each branch heat exchange pipeline. When a capillary tube 7 is damaged and needs to be replaced, first remove the cylinder 1 from the lower head 3, remove the capillary tube 7 from the mounting hole 6, turn the turntable 13, so that the screw 12 rotates, so that the moving block 14 moves along the guide rod 15. The capillary tube 7 is moved closer to each other, driving the baffle plates 16 closer to each other, until the baffle plates 16 are moved closer to the appropriate positions, and then the new capillary tube 7 is installed into the mounting hole 6 from the bottom of the mounting hole 6, until the top of the new capillary tube 7 contacts the bottom surface of the baffle plate 16. At this time, the new capillary tube 7 is the same height as the other capillaries 7. The turntable 13 is then rotated in the opposite direction to rotate the screw rod 12, so that the moving blocks 14 move away from each other along the guide rod 15, driving the baffle plates 16 away from each other, until the baffle plates 16 move away from each other to the appropriate positions, and finally the cylinder body 1 is installed on the lower head 3.

[0023] To summarize, in the Freon refrigeration liquid separation device, when a capillary tube 7 is damaged and needs to be replaced, the barrel 1 and the capillary tube 7 are removed, the turntable 13 is rotated to rotate the screw 12 so that the moving block 14 and the baffle 16 are moved closer to each other to a suitable position along the guide rod 15, and then a new capillary tube 7 is installed into the mounting hole 6 from the bottom of the mounting hole 6 until the top of the new capillary tube 7 contacts the bottom surface of the baffle 16, and then the turntable 13 is rotated in the opposite direction to move the baffles 16 away from each other to a suitable position, and finally the barrel 1 is installed back on the lower head 3, thereby achieving the goal of replacing the capillary tube 7 more quickly, and during installation, it is convenient to make the capillary tube 7 have the same height as other capillaries 7 by only making the top of the capillary tube 7 contact the bottom surface of the baffle 16, thereby reducing the time required for replacing the capillary tube 7 and solving the problems raised in the above-mentioned background technology.
