[0003] A vibration-damping four-way valve piping system and its air conditioning system are disclosed in CN216308269U. The system includes a four-way valve, which is connected to an intake pipe, an exhaust pipe, a condenser connection pipe, and a shut-off valve pipe. The exhaust pipe is equipped with a vibration-damping pipe. The vibration-damping pipe includes a corrugated pipe, a mesh sleeve, a protective sleeve, and a connecting copper pipe. The connecting copper pipe is connected to both ends of the corrugated pipe. The mesh sleeve has a mesh structure and is fitted on the outside of the corrugated pipe. Both ends of the mesh sleeve are fixed to the corrugated pipe through the protective sleeve. The protective sleeve is fixedly connected to the connecting copper pipe by welding.

[0004] The above-mentioned device achieves vibration reduction by adding a stainless steel bellows inside the exhaust pipe. However, the flexibility of the stainless steel bellows may lead to insufficient pipe sealing and leakage at the joints. Therefore, we propose a four-way valve piping assembly for air conditioners.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Example:

[0031] Please see Figures 1-6An air conditioner four-way valve piping assembly includes a four-way valve body 1, an upper connecting pipe 4, a lower connecting pipe 5, and a mounting plate 7. The four-way valve body 1 is fixedly provided with four fixed pipes 2, and each of the four fixed pipes 2 has a mounting pipe 3 at its opening. The four mounting pipes 3 are respectively connected to the compressor exhaust pipe, the compressor suction pipe, the condenser pipe, and the evaporator pipe. The upper connecting pipe 4 is fixed to the fixed pipes 2, and the lower connecting pipe 5 is fixed to the mounting pipes 3. A connecting assembly 6 for fixing and combining the upper connecting pipe 4 and the lower connecting pipe 5 is provided between the upper connecting pipe 4 and the lower connecting pipe 5. The upper connecting pipe 4 is set at the opening of the fixed pipe 2, and the lower connecting pipe 5 is set at the opening of the mounting pipe 3 that contacts the fixed pipe 2. The upper connecting pipe 4 and the lower connecting pipe 5 are combined together by connecting flanges 9, and then the two connecting flanges 9 are fixed by fixing bolts 10, thereby fixing and connecting the fixed pipe 2 and the mounting pipe 3.

[0032] Mounting plate 7 is fixedly mounted on the four-way valve body 1. An elastic telescopic rod 8 is fixedly mounted at the bottom of mounting plate 7. The elastic telescopic rod 8 is located between mounting plate 7 and upper connecting pipe 4. When mounting pipe 3 is vibrated, the vibration force will be transmitted to the connection between mounting pipe 3 and fixed pipe 2, causing the connection between mounting pipe 3 and fixed pipe 2 to shake. At this time, the elastic telescopic rod 8, which is evenly distributed on the outside of mounting pipe 3, can buffer the vibration force on the corresponding side and play a shock absorption role.

[0033] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0034] Please see Figures 1-6 By setting an upper connecting pipe 4 and a lower connecting pipe 5 at the connection between the fixed pipe 2 and the installation pipe 3, and fixing the upper connecting pipe 4 and the lower connecting pipe 5 by the connecting component 6, the fixed pipe 2 and the installation pipe 3 are fixed. When the installation pipe 3 vibrates, the elastic telescopic rod 8 set around the fixed pipe 2 can buffer the vibration in all directions, thereby ensuring the connection strength between the fixed pipe 2 and the installation pipe 3 while reducing vibration.

[0035] The connecting assembly 6 includes a connecting flange 9, which is fixedly disposed on the outside of the upper connecting pipe 4 and the lower connecting pipe 5, and a fixing bolt 10 is fixedly disposed between the two connecting flanges 9.

[0036] In addition, the elastic telescopic rod 8 includes a sleeve 11, a stop rod 12 and a compression spring 13. The sleeve 11 is fixed to the mounting plate 7, the stop rod 12 is fixed to the connecting flange 9 of the upper connecting pipe 4, and the stop rod 12 is slidably connected to the inside of the sleeve 11. The compression spring 13 is located inside the sleeve 11, with one end of the compression spring 13 fixed to the sleeve 11 and the other end fixed to the stop rod 12. Multiple elastic telescopic rods 8 are provided and are evenly distributed on the outside of the fixed pipe 2. The elastic telescopic rod 8 is used to buffer the vibration of the corresponding side of the mounting pipe 3 and the fixed pipe 2, and reduce the impact of the vibration of the mounting pipe 3 on the connection between the mounting pipe 3 and the fixed pipe 2.

[0037] Meanwhile, the upper connecting pipe 4 is provided with a first conical surface 14, and the lower connecting pipe 5 is provided with a second conical surface 15 on the outside. The second conical surface 15 cooperates with the first conical surface 14. The first conical surface 14 and the second conical surface 15 are each provided with two locations. Furthermore, the connection between the two first conical surfaces 14 and the connection between the two second conical surfaces 15 are each provided with a stepped surface 16.

[0038] The connection between the upper connecting pipe 4 and the lower connecting pipe 5 is provided with two first conical surfaces 14 and second conical surfaces 15. In addition, a stepped surface 16 is provided for the transition between the first conical surface 14 and the second conical surface 15 to improve the sealing performance of the connection between the upper connecting pipe 4 and the lower connecting pipe 5 and prevent leakage of substances inside the pipe.

[0039] The following explains the principle of ensuring the overall sealing performance of the device while damping the vibration of each mounting pipe 3 on the four-way valve body 1:

[0040] First, the upper connecting pipe 4 and the lower connecting pipe 5 are combined together by connecting flange 9. At this time, the upper connecting pipe 4 and the lower connecting pipe 5 are combined by the first conical surface 14, the second conical surface 15 and the stepped surface 16. The setting of the two first conical surfaces 14 and the second conical surface 15 ensures the sealing between the fixed pipe 2 and the installation pipe 3 after connection. Then, the two connecting flanges 9 are fixed by fixing bolts 10, thereby fixing the upper connecting pipe 4 and the lower connecting pipe 5 together.

[0041] When the mounting pipe 3 vibrates, the force of the vibration is transmitted to the connecting flange 9. Since the outer side of the fixed pipe 2 is provided with uniformly distributed elastic telescopic rods 8 in a ring, when the vibration of the mounting pipe 3 causes the connecting flange 9 to shake, the abutment rod 12 on the pressure side slides into the sleeve 11 and squeezes the compression spring 13. The compression spring 13 buffers the vibration pressure on the corresponding side, thereby achieving the vibration reduction effect between the four-way valve body 1 and the mounting pipe 3.

[0042] In this technical solution, compared with the traditional method of fixing each pipeline to the four-way valve by welding, the installation pipe 3 and the fixed pipe 2 are fixed by fixing bolts 10 and connecting flange 9. When the installation pipe 3 is damaged and needs to be replaced for maintenance, it is convenient to disassemble and replace the installation pipe 3.

[0043] In this technical solution, such as Figure 3 and Figure 4 As shown, the outer sides of both the upper connecting pipe 4 and the lower connecting pipe 5 are tapered. The tapered upper connecting pipe 4 and the lower connecting pipe 5 can disperse the stress at the connection between the upper connecting pipe 4 and the fixed pipe 2 and at the connection between the lower connecting pipe 5 and the mounting pipe 3, thus preventing stress concentration.

[0044] In this technical solution, such as Figure 5As shown, the upper connecting pipe 4 and the lower connecting pipe 5 have the same inner diameter, which reduces the flow resistance of the fluid flowing through the upper connecting pipe 4 and the lower connecting pipe 5, thereby reducing the generation of eddies when the fluid flows through, and thus reducing the possibility of vibration of the mounting pipe 3.

[0045] In this technical solution, such as Figure 3 and Figure 4 As shown, a recessed groove 17 is provided in the stepped surface 16, and a sealing gasket 18 is embedded in the recessed groove 17. The sealing gasket 18 can further improve the sealing performance of the upper connecting pipe 4 and the lower connecting pipe 5 when fixedly connected.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
