Description

Technical Field

[0001] The utility model relates to the field of condensing tubes, in particular to a gas-liquid separation condensing tube used for a central air conditioner. Background Art

[0002] During the refrigeration cycle of the central air conditioner, the refrigerant absorbs heat in the evaporator and becomes gaseous, then enters the compressor for compression, passes through the condenser for cooling and condensation, and finally returns to the evaporator to continue circulating. In this process, the main function of the gas-liquid separation condenser is to achieve effective separation of refrigerant vapor and liquid.

[0003] The gas-liquid separation condenser of the central air conditioner is responsible for transferring the heat in the condenser to the outside air. The existing condenser tubes are often fixed and connected by bolts. The bolt connection method makes the disassembly and installation of the condenser tube very inconvenient. When the condenser tube needs to be replaced or repaired, a lot of time will be wasted on tightening the bolts, which is time-consuming and laborious. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a gas-liquid separation condensing tube for a central air conditioner.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a gas-liquid separation condenser pipe for a central air conditioner, comprising a fixed pipe, the front side surface of the fixed pipe is fixedly connected to a first flange, the front side of the first flange is provided with a connecting pipe, the back side of the connecting pipe is fixedly connected to a second flange, the outer surface of the fixed pipe is threadedly connected to a sleeve, the outer surface of the sleeve is fixedly connected to a rotating frame, a rotating groove is provided inside the rotating frame, a bayonet is provided inside the rotating groove, the number of the bayonet is plural, the interior of the bayonet is fixedly connected to a fixed column, and the outer surface of the fixed column is sleeved with a rotating pin.

[0006] As a further description of the above technical solution:

[0007] The outer surface of the bayonet is sleeved with a first flange, the outer surface of the bayonet is sleeved with a second flange, and the cross-sectional shape of the rotation groove is trapezoidal.

[0008] As a further description of the above technical solution:

[0009] A sealing groove is provided on the front side of the fixing tube, and a sealing ring is fixedly connected to the inner surface of the sealing groove.

[0010] As a further description of the above technical solution:

[0011] The outer surface of the connecting pipe is fixedly connected with a mounting tube, and the outer surface of the mounting tube is fixedly connected with a heat dissipation fin, and the number of the heat dissipation fins is multiple.

[0012] As a further description of the above technical solution:

[0013] The back side of the fixed tube is fixedly connected with a separation tube, the inner surface of the separation tube is fixedly connected with a limiting plate, and the cross-sectional shape of the limiting plate is a parallelogram.

[0014] As a further description of the above technical solution:

[0015] The upper surface of the separation tube is provided with a gas outlet, and the lower surface of the separation tube is provided with a liquid outlet.

[0016] The utility model has the following beneficial effects:

[0017] Compared with the prior art, the gas-liquid separation condensing pipe for central air conditioning, through the rotating pin, the fixed column, the bayonet pin, the first flange, the second flange, the sleeve, the fixed pipe and the rotating frame, firstly rotates the rotating pin along the fixed column to the inside of the bayonet pin, so that the bayonet groove on the second flange corresponds to the bayonet pin, and then moves the second flange to a position that fits with the first flange along the bayonet pin, and then rotates the rotating pin along the fixed column to a position perpendicular to the bayonet pin, and then rotates the sleeve, and then drives the sleeve to move backward along the fixed pipe, and then drives the rotating frame to move backward, and then drives the bayonet pin to move backward When the rotatable pin contacts the front surface of the second flange, the rotatable pin begins to limit the second flange, and the locking pin continues to be moved backward, so the rotatable pin will tightly fix the second flange. Compared with the existing condenser, the condenser tubes are often fixed and connected by bolts. The bolt connection method makes the disassembly and installation of the condenser tube very inconvenient. When the condenser tube needs to be replaced or repaired, a lot of time will be wasted on tightening the bolts, which is time-consuming and laborious. The gas-liquid separation condenser tube of the central air conditioner can more conveniently disassemble and assemble adjacent condenser tubes, which can greatly save the time for disassembly and assembly of the condenser tube.

[0018] Compared with the prior art, the gas-liquid separation condenser tube for central air conditioning includes a limiting plate, a fixed tube, a liquid outlet, an air outlet and a separation tube. The limiting plate allows the gas-liquid mixture passing through the fixed tube to collide with the limiting plate, so that the gas-liquid mixture is buffered. The liquid flows downward along the limiting plate and flows out from the liquid outlet, and most of the gas is discharged through the air outlet. A small part of the gas entrained by the liquid will eventually rise along the separation tube, finally move upward from the left side of the limiting plate, and finally be discharged from the air outlet, thereby achieving a better gas-liquid separation effect.

When the rotating pin 12 contacts the front surface of the second flange 4, the rotating pin 12 begins to limit the second flange 4, and the bayonet 10 is continued to be moved backward. Then, the rotating pin 12 will tightly fix the second flange 4. There are multiple bayonet pins 10, and the interior of the bayonet pin 10 is fixedly connected to the fixing column 11, and the outer surface of the fixing column 11 is sleeved with a rotating pin 12.
