Description

Technical Field

[0001] This utility model relates to the field of refrigeration processing technology, and in particular to a detachable refrigeration copper tube for refrigeration equipment. Background Technology

[0002] In modern society, refrigeration equipment has been deeply integrated into various fields. In the commercial sector, large refrigerators and cold storage facilities in supermarkets bear the heavy responsibility of food preservation and goods storage, ensuring the quality of various perishable products. In industrial production, many processes require specific low-temperature environments, such as chip cooling in electronic component manufacturing and temperature control in chemical synthesis, and refrigeration equipment provides a guarantee for their stable operation. In daily life, air conditioners regulate indoor temperature, and refrigerators store food, bringing comfort and convenience to people.

[0003] However, most existing methods of connecting refrigeration copper pipes to refrigeration equipment use welding, which has the following problems:

[0004] 1. When the refrigeration copper pipe is damaged, the irreversible nature of the welding makes the replacement process extremely complicated. It not only requires a lot of manpower and time to separate the refrigeration copper pipe from the refrigeration equipment, but also requires a complicated welding operation to complete the connection of the new copper pipe.

[0005] 2. The existing refrigeration copper pipes, once connected to the equipment, lack stability. Even slight external force can easily cause gaps to appear between the refrigeration copper pipes and the equipment. This not only severely affects the cooling effect of the refrigeration equipment and reduces energy efficiency, but may also lead to safety hazards such as refrigerant leaks.

[0006] When applying for this invention, the applicant searched and found a Chinese patent that discloses a "refrigeration device" with application number "202220232316.3". This patent mainly uses a pipe mechanism and four support blocks. The pipe mechanism has fixed and movable connections to fixing mechanisms on both sides, placement blocks fixedly connected to both sides on the lower end of the pipe mechanism, and snap-fit ​​mechanisms fixedly connected to both sides on the upper end of the pipe mechanism to connect the refrigeration copper pipe. However, the snap-fit ​​structure has poor vibration resistance. The snap-fit ​​blocks may momentarily detach from the snap-fit ​​state with the upper snap-fit ​​plate, causing displacement of the pipe mechanism. In severe cases, it may cause problems such as pipe rupture and refrigerant leakage, affecting the normal operation and service life of the refrigeration device. Utility Model Content

[0007] The purpose of this utility model is to provide a detachable refrigeration copper pipe for refrigeration equipment, in order to solve the problems of poor vibration resistance, potential pipe rupture, and refrigerant leakage in existing detachable refrigeration copper pipes for refrigeration equipment.

[0009] According to the detachable refrigeration copper tube of the refrigeration equipment, the left end of the refrigeration copper tube 2 is provided with a second threaded groove, and a second slot is opened on the right side of the refrigeration copper tube 2 near the second threaded groove.

[0010] According to the detachable refrigeration copper pipe of the refrigeration equipment, the first flange has a plurality of first openings, and the first flange and the second flange are clearance-fitted.

[0011] According to the detachable refrigeration copper pipe of the refrigeration equipment, a sealing ring is fitted on the second slot, and the sealing ring is attached to the inner wall of the connection port of the refrigeration equipment.

[0012] According to the detachable refrigeration copper pipe of the refrigeration equipment, the second flange is provided with a plurality of second openings, which are adapted to the first openings.

[0013] According to the detachable refrigeration copper pipe of the refrigeration equipment, a bolt is provided on the second flange, the bolt passes through the first opening and the second opening, and a nut is threadedly fixed on the left side of the bolt near the first flange.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This patent provides a connection between the first threaded groove and the first slot in the refrigeration equipment connection port and the threaded pipe and the second slot on the refrigeration copper pipe, as well as a sealing ring fitted on the second slot. In use, this connection of the refrigeration copper pipe is used to prevent refrigerant leakage.

[0016] 2. This patent, through the setting of the first flange and the second flange, serves to flange the connection between the refrigeration equipment and the refrigeration copper pipe, avoiding pipe rupture and refrigerant leakage that may be caused by the loosening of the threaded pipe due to vibration.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4This utility model discloses a detachable refrigeration copper pipe for a refrigeration device, comprising a refrigeration device connection port 1, a first flange 5 fixedly installed at the right end of the refrigeration device connection port 1, a first threaded groove 7 formed inside the refrigeration device connection port 1, a first slot 8 formed at the right end of the refrigeration device connection port 1 near the first threaded groove 7, a refrigeration copper pipe 2 threadedly connected to the inner wall of the right end of the refrigeration device connection port 1, a second flange 11 fixedly installed on the refrigeration copper pipe 2, and a threaded pipe 9 provided at the left end of the refrigeration copper pipe 2, with a second slot 10 formed at the right side of the threaded pipe 9. By using the first threaded groove 7 inside the refrigeration device connection port 1 and the threaded pipe 9 at the left end of the refrigeration copper pipe 2, the refrigeration copper pipe 2 is threadedly connected to the refrigeration device connection port 1 during use. This makes installation simple and quick, allowing construction personnel to easily connect and disassemble the pipe with only simple tools such as wrenches, greatly improving construction efficiency, reducing labor intensity, and significantly shortening the project cycle compared to other complex connection methods. From the perspective of connection stability, threaded connections can provide reliable fastening force, maintaining a tight connection even under the pressure of the medium inside the pipeline and the forces of the external environment, effectively preventing pipeline leakage. At the same time, its good sealing performance is also crucial. In addition, threaded connections have high repeatability, which facilitates the later maintenance and repair of the pipeline system. When a section of the pipeline has a problem, it can be quickly disassembled and replaced without affecting other parts of the entire system, effectively reducing maintenance costs and improving the overall service life and reliability of the pipeline system.

[0027] The first flange 5 has several first openings 6, and the first flange 5 and the second flange 11 are clearance-fitted. A sealing ring 13 is fitted onto the second groove 10, and the sealing ring 13 fits against the inner wall of the first groove 8 opened in the refrigeration equipment connection port 1. By fitting the sealing ring 13 onto the second groove 10 and adding sealing material at the thread, the sealing effect can be further enhanced, ensuring the safe transportation of various fluid media in the pipeline.

[0028] The second flange 11 has several second openings 12, which are adapted to the first opening 6. Bolts 3 are installed on the second flange 11, passing through the first opening 6 and the second opening 12. A nut 4 is threaded onto the left side of the bolt 3 near the first flange 5. The fixing of the first flange 5 and the second flange 11 with bolts 3 and nuts 4 simplifies installation. Construction personnel only need simple tools such as wrenches to tighten and loosen the bolts 3, without requiring complex professional skills or large equipment. During the installation, commissioning, and subsequent maintenance of the pipeline system, the pipeline can be quickly assembled and disassembled. When a fault occurs and a pipeline section needs repair or replacement, removing the bolts 3 allows for separation of the corresponding part, greatly improving maintenance efficiency and reducing maintenance costs and time. Furthermore, under the tightening action of the bolts 3 and nuts 4, the two flanges fit tightly together, capable of withstanding significant internal pipeline pressure and external tensile and bending mechanical stresses.

[0029] Working principle: In use, firstly, a sealing ring 13 is fitted onto the second slot 10 opened on the refrigeration copper pipe 2. Then, the refrigeration copper pipe 2 with threaded pipe 9 is threaded to the inner wall of the refrigeration equipment connection port 1, so that the sealing ring 13 fits against the inner wall of the first slot 8, thereby achieving a stable connection and providing reliable fastening force. Under the pressure of the medium inside the pipe and the force of the external environment, it can still maintain a tight connection, effectively preventing pipe leakage. After the first flange 5 and the second flange 11 are fitted with a clearance, the first flange 5 and the second flange 11 are fixed with bolts 3 and nuts 4, thereby achieving secondary fixation of the refrigeration copper pipe 2 and the refrigeration equipment connection port 1. The two flanges fit tightly together and can withstand greater internal pipe pressure and external tensile, bending and other mechanical stresses, avoiding pipe rupture and refrigerant leakage that may be caused by the threaded pipe 9 loosening due to vibration.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
