Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a compressor for refrigeration and air conditioning. Background Technology

[0002] A compressor is a driven fluid machine that raises 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, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. The compressor is considered the heart of the refrigeration system, and the most specific term describing its characteristics is "vapor pump." The compressor's actual function is to increase pressure, raising the suction pressure to the discharge pressure.

[0003] The existing single-sided compressor requires welding the external pipes to the compressor pipes during use. However, during long-term operation, the external pipes and the compressor pipes are prone to detachment from the weld, which can lead to leakage and affect the compressor's performance.

[0004] To address the aforementioned issues, a compressor for refrigeration and air conditioning is proposed. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a compressor for refrigeration and air conditioning that can solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compressor for refrigeration and air conditioning, comprising a compressor pipe provided on the top of the compressor, a connecting pipe welded inside the compressor pipe, a fixed sealing plate fixedly installed on the surface of the connecting pipe, a sliding sealing plate slidably connected to the surface of the compressor pipe, a sealing cover fixedly installed on the surface of the sliding sealing plate, a fixed plate fixedly installed on the surface of the compressor pipe, a second rubber sealing gasket provided on the side of the fixed plate near the sliding sealing plate, the second rubber sealing gasket contacting the sliding sealing plate, bolts slidably connected inside the fixed sealing plate and the sliding sealing plate, and nuts threadedly connected to the surface of the bolts.

[0007] Preferably, a groove is provided on one side of the fixed sealing plate, and a first rubber sealing gasket is fixedly installed on the upper side of the sealing cover, the first rubber sealing gasket being slidably connected inside the groove.

[0008] Preferably, a connecting cylinder is fixedly installed on the outside of the sealing cover, and the connecting cylinder communicates with the inside of the sealing cover.

[0009] Preferably, a sliding rod is slidably connected inside the connecting cylinder, and a sealing ring is provided at the sliding connection between the sliding rod and the connecting cylinder.

[0010] Preferably, a piston plate is fixedly installed at one end of the slide rod inside the connecting cylinder, and the piston plate is slidably connected inside the connecting cylinder.

[0011] Preferably, a third rubber sealing gasket is fixedly installed on the piston plate, and the third rubber sealing gasket is in contact with the inner wall of the connecting cylinder.

[0012] Preferably, a spring is movably sleeved on the surface of the slide rod, with the end of the spring near the piston plate fixedly connected to the piston plate and the end of the spring away from the piston plate fixedly connected to the inner wall of the connecting cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) The compressor for refrigeration and air conditioning uses a sealing cover to achieve secondary sealing of the connection between the compressor pipe and the connecting pipe, thereby preventing leakage when the compressor pipe and the connecting pipe come off. This improves the protection effect and facilitates secondary reinforcement of the connection between the compressor pipe and the connecting pipe, thereby improving the reinforcement effect and reducing the risk of detachment.

[0014] (2) When the compressor pipe and connecting pipe of the refrigeration air conditioner leak, gas will enter the inside of the sealing cover, which will increase the gas pressure inside the sealing cover and squeeze the piston plate. This will cause the piston plate and the third rubber sealing gasket to slide inside the connecting cylinder. At the same time, when the piston plate moves, it will squeeze the spring spring and cause the slide rod to move outward. This makes it easier for maintenance personnel to judge whether there is a leak in the compressor pipe and connecting pipe by observing the length of the slide rod during maintenance, thus further improving the convenience of maintenance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a compressor for refrigeration and air conditioning, including a compressor 1, a compressor pipe 2 provided on the top of the compressor 1, a connecting pipe 3 welded inside the compressor pipe 2, a fixed sealing plate 4 fixedly installed on the surface of the connecting pipe 3, a sliding sealing plate 7 slidably connected to the surface of the compressor pipe 2, a sealing cover 5 fixedly installed on the surface of the sliding sealing plate 7, a fixed plate 13 fixedly installed on the surface of the compressor pipe 2, a second rubber sealing gasket 14 provided on the side of the fixed plate 13 near the sliding sealing plate 7, the second rubber sealing gasket 14 contacting the sliding sealing plate 7, a bolt 6 slidably connected inside the fixed sealing plate 4 and the sliding sealing plate 7, and a nut 8 threadedly connected to the surface of the bolt 6.

[0020] Rotate bolt 6 to remove bolt 6 and nut 8 from fixed sealing plate 4 and sliding sealing plate 7, thereby moving sliding sealing plate 7 and sealing cover 5 downwards. Then, insert connecting pipe 3 into the inside of compressor pipe 2, and weld compressor pipe 2 and connecting pipe 3. After welding compressor pipe 2 and connecting pipe 3 is completed, move sliding sealing plate 7 on compressor pipe 2, and then install bolt 6 and nut 8 on fixed sealing plate 4 and sliding sealing plate 7. When tightening bolt 6 and nut 8, move sliding sealing plate 7 on compressor pipe 2, thereby squeezing the second rubber sealing gasket 14 to achieve a seal between sliding sealing plate 7 and compressor pipe 2. Then, through sealing cover 5, a secondary seal is achieved at the connection between compressor pipe 2 and connecting pipe 3, thereby preventing leakage when compressor pipe 2 and connecting pipe 3 detach. This improves the protection effect and facilitates secondary reinforcement of the connection between compressor pipe 2 and connecting pipe 3, thereby improving the reinforcement effect and reducing the risk of detachment.

[0021] A groove 11 is provided on one side of the fixed sealing plate 4, and a first rubber sealing gasket 12 is fixedly installed on the upper side of the sealing cover 5. The first rubber sealing gasket 12 is slidably connected inside the groove 11.

[0022] When the sliding sealing plate 7 and the fixed sealing plate 4 approach each other, the sealing cover 5 will enter the interior of the groove 11, thereby squeezing the first rubber sealing gasket 12 and sealing the connection between the sealing cover 5 and the fixed sealing plate 4, thus preventing leakage and improving the sealing effect.

[0023] A connecting cylinder 9 is fixedly installed on the outside of the sealing cover 5. The connecting cylinder 9 communicates with the inside of the sealing cover 5. A sliding rod 10 is slidably connected inside the connecting cylinder 9. A sealing ring is provided at the sliding connection between the sliding rod 10 and the connecting cylinder 9. A piston plate 16 is fixedly installed at one end of the sliding rod 10 inside the connecting cylinder 9. The piston plate 16 is slidably connected inside the connecting cylinder 9. A third rubber sealing gasket 17 is fixedly installed on the piston plate 16. The third rubber sealing gasket 17 contacts the inner wall of the connecting cylinder 9. A spring spring 15 is movably sleeved on the surface of the sliding rod 10. The end of the spring spring 15 near the piston plate 16 is fixedly connected to the piston plate 16, and the end of the spring spring 15 away from the piston plate 16 is fixedly connected to the inner wall of the connecting cylinder 9.

[0024] When a leak occurs in the compressor pipe 2 and the connecting pipe 3, gas will enter the interior of the sealing cover 5, increasing the internal pressure and squeezing the piston plate 16. This causes the piston plate 16 and the third rubber sealing gasket 17 to slide inside the connecting cylinder 9. Simultaneously, as the piston plate 16 moves, it squeezes the spring spring 15, causing the slide rod 10 to move outward. This allows maintenance personnel to easily determine whether there is a leak in the compressor pipe 2 and the connecting pipe 3 by observing the length of the slide rod 10, further improving the convenience of maintenance.

[0025] Working principle: Rotate bolt 6 to remove bolt 6 and nut 8 from fixed sealing plate 4 and sliding sealing plate 7, thereby moving sliding sealing plate 7 and sealing cover 5 downwards. Then, insert connecting pipe 3 into the inside of compressor pipe 2, and weld compressor pipe 2 and connecting pipe 3. After welding compressor pipe 2 and connecting pipe 3 is completed, move sliding sealing plate 7 on compressor pipe 2, and then install bolt 6 and nut 8 on fixed sealing plate 4 and sliding sealing plate 7. When tightening bolt 6 and nut 8, move sliding sealing plate 7 on compressor pipe 2, thereby squeezing the second rubber sealing gasket 14 to achieve a seal between sliding sealing plate 7 and compressor pipe 2. Then, through sealing cover 5, a secondary seal is achieved at the connection between compressor pipe 2 and connecting pipe 3, thereby preventing leakage at the connection between compressor pipe 2 and connecting pipe 3 in the event of detachment.

[0026] When a leak occurs between the compressor pipe 2 and the connecting pipe 3, gas will enter the interior of the sealing cover 5, increasing the internal pressure and squeezing the piston plate 16. This causes the piston plate 16 and the third rubber sealing gasket 17 to slide inside the connecting cylinder 9. Simultaneously, as the piston plate 16 moves, it squeezes the spring spring 15, causing the slide rod 10 to move outward. This allows maintenance personnel to easily determine whether there is a leak between the compressor pipe 2 and the connecting pipe 3 by observing the length of the slide rod 10 during maintenance.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
