Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
[0020] The piping components provided in the embodiments of this application, such as Figures 1 to 6 As shown, it includes: a corrugated pipe 100, which includes a first main body portion 110 and a first connector portion 120 connected to each other; a connecting pipe 200, which includes a second main body portion 210 and a second connector portion 220 connected to each other, with the first connector portion 120 inserted into the second connector portion 220; and a braided mesh sleeve 300, which includes a third main body portion 310 and a sealing fit portion 320 connected to each other, with the third main body portion 310 sleeved outside the first main body portion 110, and the sealing fit portion 320 disposed between the first connector portion 120 and the second connector portion 220 and sealed to the first connector portion 120 and the second connector portion 220.
[0021] The pipeline assembly includes a corrugated pipe 100 comprising a first main body portion 110 and a first connector portion 120 connected together; a connecting pipe 200 comprising a second main body portion 210 and a second connector portion 220 connected together; and a braided mesh sleeve 300 comprising a third main body portion 310 and a sealing fit portion 320 connected together. The third main body portion 310 is fitted outside the first main body portion 110, the first connector portion 120 is inserted into the second connector portion 220, and the sealing fit portion 320 is located between the first connector portion 120 and the second connector portion 220 and is sealed to the first connector portion 120 and the second connector portion 220. This achieves the connection of the corrugated pipe 100, the braided mesh sleeve 300, and the connecting pipe 200 together. This pipeline assembly solution is simple, has few connection steps, and the connection operation is time-saving.
[0022] In some embodiments, the first joint portion 120, the second joint portion 220, and the sealing mating portion 320 are all made of metal, and the sealing mating portion 320 is welded and sealed to the first joint portion 120 and the second joint portion 220 by brazing or argon arc welding. In this way, the first joint portion 120, the second joint portion 220, and the sealing mating portion 320 can be welded together in one welding or one argon arc welding process (e.g., filling the space between the first joint portion 120 and the sealing mating portion 320 and the second joint portion 220 and the sealing mating portion 320 respectively with welding wire or welding ring, and then welding together by brazing or argon arc welding). This method has fewer welding steps and shorter welding time.
[0023] The metals used are stainless steel, copper, aluminum, aluminum alloys, or titanium alloys, etc. All of these can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention. They will not be described in detail here, and all should fall within the protection scope of this application.
[0024] In some embodiments, such as Figures 1 to 4 As shown, the first connector portion 120 includes a connecting straight pipe section 121 and a connecting corrugated section 122. The connecting straight pipe section 121 is connected to the first main body portion 110 through the connecting corrugated section 122. The second connector portion 220 includes a first mating straight pipe section 221 and a second mating straight pipe section 222. The second mating straight pipe section 222 is connected to the second main body portion 210 through the first mating straight pipe section 221. The sealing mating portion 320 includes a first sealing mating section 321 and a second sealing mating section 322. The sealing section 321 is connected to the third main body 310 via the second sealing section 322. The outer circumferential surface of the connecting straight pipe section 121 is sealed to the inner circumferential surface of the first sealing section 321. The inner circumferential surface of the first mating straight pipe section 221 is sealed to the outer circumferential surface of the first sealing section 321. The crest of the outer circumferential surface of the connecting corrugated section 122 is sealed to the inner circumferential surface of the second sealing section 322. The inner circumferential surface of the second mating straight pipe section 222 is sealed to the outer circumferential surface of the second sealing section 322. In this scheme, the first joint part 120 and the sealing section 320 are welded together not only through the connecting straight pipe section 121 and the first sealing section 321, but also through the connecting corrugated section 122 and the second sealing section 322. This results in a higher connection strength and better sealing between the first joint part 120 and the sealing section 320.
[0025] Of course, it can also be, such as Figure 5As shown, the first joint portion 120 includes only the connecting straight pipe section 121 and does not include the connecting corrugated section 122, and the sealing mating portion 320 includes only the first sealing mating section 321 and does not include the second sealing mating section 322. The first joint portion 120 and the sealing mating portion 320 are connected by welding only through the connecting straight pipe section 121 and the first sealing mating section 321. Alternatively, the first joint portion 120 may include only the connecting corrugated section 122 and not the connecting straight pipe section 121, and the sealing mating portion 320 may include only the second sealing mating section 322 and not the first sealing mating section 321. The first joint portion 120 and the sealing mating portion 320 are connected by welding only through the connecting corrugated section 122 and the second sealing mating section 322. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention. They will not be elaborated here, and should all fall within the protection scope of this application.
[0026] In some embodiments, such as Figure 2 As shown, the outer diameter of the connecting straight pipe section 121 is smaller than the maximum outer diameter of the connecting corrugated section 122. This results in a larger radial gap between the connecting straight pipe section 121 and the first sealing mating section 321, making it easier to ensure that a continuous and stable weld layer is formed between the connecting straight pipe section 121 and the first sealing mating section 321 during brazing. Therefore, this scheme results in higher connection strength and better sealing between the connecting straight pipe section 121 and the first sealing mating section 321.
[0027] It can be, such as Figure 4 As shown, the second main body portion 210 is a U-shaped tube portion; or it can be a straight tube portion; or it can be a folded tube portion, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention. They will not be described in detail here, and all should fall within the protection scope of this application.
[0028] In some embodiments, such as Figure 2 As shown, the first main body portion 110 and the first connector portion 120 are an integral structure, as... Figure 4 As shown, the second main body 210 and the second connector 220 are integral structures, such as the second connector 220 being manufactured using a flaring process (e.g.) Figure 5 As shown in the figure, this reduces the number of welding steps for the corrugated pipe, braided mesh sleeve, and connecting pipe, and shortens the welding operation time.
[0029] Alternatively, the second main body 210 and the second connector 220 can be separate structures (not shown in the figure of this scheme), such as the second main body 210 and the second connector 220 being connected separately by plug-in welding, but this scheme will increase the welding steps of the connecting pipe and extend the welding operation time.
[0030] The four-way valve module (not shown in the figure) provided in this application embodiment includes a four-way valve assembly 500 and a pipeline assembly as described in any of the above embodiments. The air inlet pipe of the four-way valve assembly 500 includes a connecting pipe 200.

[0033] This compressor module possesses all the advantages of the piping components provided in any of the above embodiments, and will not be elaborated further here.
[0034] The air conditioning equipment provided in this application embodiment, such as Figure 6 As shown, the assembly includes a compressor assembly 400, a four-way valve assembly 500, and a piping assembly as described in any of the above embodiments. The exhaust pipe of the compressor assembly 400 is connected to the intake pipe of the four-way valve assembly 500 via a connecting pipe.

[0035] This air conditioning equipment possesses all the advantages of the piping components provided in any of the above embodiments, which will not be elaborated further here.
[0036] In some embodiments, the exhaust pipe of the compressor assembly 400 is a connecting pipe 200, and the intake pipe of the four-way valve assembly 500 is a connecting pipe 200. In this way, the connection scheme between the exhaust pipe of the compressor assembly 400 and the bellows 100 is simple, with fewer connection steps and shorter connection operation time. Similarly, the connection scheme between the intake pipe of the four-way valve assembly 500 and the bellows 100 is simple, with fewer connection steps and shorter connection operation time.
