Description

Technical Field

[0001] This utility model relates to the field of compressor distributors, and in particular to a compressor distributor that is easy to assemble. Background Technology

[0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle and thus realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). Compressors are classified into reciprocating compressors, screw compressors, centrifugal compressors, linear compressors, etc. A liquid separator, also called a gas-liquid separator, separates the liquid and gas in the refrigerant, preventing liquid from slugging into the compressor and ensuring its safe and normal operation.

[0003] However, traditional compressor distributors, such as the technical solution disclosed in the patent application number CN201610842096.5 entitled "Compressor Distributor and Compressor", are inconvenient to assemble and have low assembly efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a compressor distributor that is easy to assemble, addressing the technical problems of traditional compressor distributors being inconvenient to assemble and having low assembly efficiency.

[0005] An easy-to-assemble compressor distributor includes: an inlet pipe, a top cover, a separating plate, a tank, a bottom cover, an outlet pipe, and an isolation cover.

[0006] The output end of the input tube is connected to the top of the upper cover. A stop ring is provided on the inner wall of the end of the upper cover away from the input tube. A first internal thread is provided on the inner wall of the end of the upper cover away from the input tube, and the first internal thread is located below the stop ring. A first sealing ring is provided on the end of the upper cover away from the input tube. A plurality of first separation holes are evenly opened on the separation plate. The separation plate abuts against the stop ring.

[0007] The tank body is a circular tubular structure. An upper connecting threaded tube is provided on the inner wall of the top of the tank body. The upper connecting threaded tube is adapted to the first internal thread and is screwed to the top cover via the first internal thread. The upper connecting threaded tube abuts against the side of the separation plate facing away from the stop ring. A first abutting ring is provided on the top of the tank body near the upper connecting threaded tube. A first annular sealing groove is formed on the top of the first abutting ring. The first sealing ring is adapted to the first annular sealing groove and can be inserted into the first annular sealing groove, sealingly abutting against the first abutting ring. The first abutting ring abuts against the end of the top cover away from the input pipe. A first annular weld joint is formed between one end of the top of the tank body and the top cover. A second internal thread is provided on the inner wall of the end of the tank body away from the upper connecting threaded tube, and a second sealing ring is provided at the end of the tank body away from the upper connecting threaded tube.

[0008] The bottom cover has a second abutment ring on its edge, and a second annular sealing groove is formed on the top of the second abutment ring. The second sealing ring is adapted to the second annular sealing groove and can be inserted into the second annular sealing groove to seal against the second abutment ring. The second abutment ring abuts against the end of the tank body away from the upper connecting threaded pipe. A second annular weld joint is formed between the edge of the bottom cover and the tank body. The bottom cover has a lower connecting threaded pipe on its edge, which is adapted to the second internal thread and is screwed to the tank body through the second internal thread.

[0009] The input end of the output pipe passes through the bottom cover and is inserted into the tank; the isolation cover is a hollow cylindrical structure, the isolation cover is wrapped around the input end of the output pipe and connected to the output pipe, and a number of second separation holes are evenly opened at the bottom of the isolation cover.

[0010] In one embodiment, the input tube is integrally formed with the top cover.

[0011] In one embodiment, the stop ring is integrally formed with the top cover.

[0012] In one embodiment, the first abutment ring is integrally formed with the tank body.

[0017] In one embodiment, the lower connecting threaded tube and the bottom cover are integrally formed.

[0018] In one embodiment, the output tube is integrally formed with the bottom cover.

[0019] In operation, the aforementioned easily assembled compressor distributor allows gaseous refrigerant mixed with liquid refrigerant to enter the upper cover through the inlet pipe. After passing through the first separation holes on the separation plate, the first gas-liquid separation is completed. It then enters the tank body and undergoes a second gas-liquid separation after passing through the second separation holes at the bottom of the isolation cover. Finally, the gaseous refrigerant is discharged to the outside through the outlet pipe. During assembly, the inlet pipe and upper cover are inverted, and the separation plate is placed on the retaining ring. The upper connecting threaded pipe is screwed to the upper cover through the first internal thread, pressing and fixing the separation plate onto the retaining ring. The first sealing ring is inserted into the first annular sealing groove and seals against the first abutment ring. The lower connecting threaded pipe is screwed to the tank body through the second internal thread, and the second abutment ring abuts against the end of the tank body away from the upper connecting threaded pipe. Simultaneously, the second sealing ring is inserted into the second annular sealing groove and seals against the second abutment ring. During this process, the bottom cover brings the outlet pipe and isolation cover into the tank body. Using an external welding machine, welding is performed at the first and second annular weld joints to weld the top cover, tank body, and bottom cover together. This easily assembled compressor distributor is convenient to assemble and has high assembly efficiency. Attached Figure Description
