It is a valve that realizes the communication, cutting and reversing of hydraulic fluid, as well as pressure unloading and sequential action control. It can be divided into manual reversing valve, solenoid reversing valve, electro-hydraulic reversing valve, etc. When working, it drives the valve core and valve stem to move position by external force, connects or cuts off different fluid inlets and outlets, so that the fluid flows from one group of inlets and outlets and from another group of inlets and outlets, achieving the purpose of periodic flow change. The two-position five-way reversing valve is an automation basic component used to control fluids. It belongs to an actuator and is not limited to hydraulic or pneumatic control.

[0003] The existing two-position five-way reversing valve mostly adopts a sliding column type reversing valve, which has a small internal channel space, resulting in a small fluid flow rate and cannot meet the needs of large flow control. The traditional air valve only has the functions of opening and closing, and the air comes from one direction and cannot be switched. The traditional four-way ventilation valve needs to rotate the alignment interface, and the docking of the moving parts is unreliable. The inlet and outlet of the four-way ventilation valve are two independent devices, not integrated components, and cannot be linked, making it difficult to switch the flow channel. Summary of the invention

[0004] The purpose of the present invention is to provide a five-position reversing air valve with a compact design, small footprint, and easy installation and integration into an existing system. Through an integrated mobile component, precise linkage between the air valve plates is ensured, and the air flow direction can be precisely controlled according to different needs, thereby reducing manual operation and improving the system's automation level and operating efficiency.

[0024] Embodiment 1

[0025] like Figure 1 , 3 As shown, the present invention provides a five-position reversing air valve, including an air valve body, which is square, and a controller 2 is fixedly installed on one side above the air valve body 1. The controller 2 has a signal receiving function and can convert the received electrical signal into a precise mechanical motion. A motor 10 is arranged on one side of the controller 2, and the motor 10 is electrically connected to the controller 2. The motor 10 is connected to the driving gear 9, and a driven gear 13 is symmetrically arranged on one side of the driving gear 9. When the controller 2 receives a signal, the motor 10 is started, and the controller 2 controls the motor 10 to drive the driving gear 9 to rotate through a preset program therein.

[0026] A moving assembly is provided on the upper surface of the air valve body 1, and the moving assembly includes a translation rack 3, a driving gear 9, and a driven gear 13. The driving gear 9 can control the translation rack 3, so as to facilitate the subsequent reversing control. The translation rack 3 is arranged between the driving gear 9 and the driven gear 13, and a limit block 8 is arranged on the translation rack 3. The right side of the limit block 8 is called the right movable part of the translation rack 3, and the left side of the limit block 8 is called the left movable part of the translation rack 3. The right movable part of the translation rack 3 is meshed and connected with the driving gear 9 and the driven gear 13.

[0027] When the driving gear 9 and the driven gear 13 rotate, the right movable part of the translation rack 3 can achieve stable horizontal movement. The cooperation between the driving gear 9 and the driven gear 13, and the stable movement of the translation rack 3, improve the efficiency and reliability of the moving assembly. Limit blocks 8 are set at both ends of the right movable part of the translation rack 3, and the movement range of the right movable part of the translation rack 3 is always between the limit blocks 8. The function of the limit block 8 is to prevent the driving gear 9 and the driven gear 13 from rotating, and prevent the translation rack 3 from moving beyond the position preset by the program.

[0028] A guide groove 11 is provided at one end of the air valve body 1 away from the controller 2, and the guide groove 11 is fixedly connected to the air valve body 1. The left movable part of the translation rack 3 extends into the guide groove 11 and fits tightly with the guide groove 11. When the translation rack 3 moves horizontally, the left movable part of the translation rack 3 is always in the guide groove 11, and cooperates with the limit block 8 provided on the right movable part of the translation rack 3 to ensure that the left movable part of the translation rack 3 will not fall out of the guide groove 11. The design of the limit block 8 and the guide groove 11 prevents the translation rack 3 from deviating from the defined position during movement, thereby ensuring the safe operation of the system.

[0029] The damper body 1 is provided with a limit slot 7, and the mounting positions are arranged in the limit slot 7 at a fixed interval, ensuring that the damper components are evenly distributed in the limit slot 7. Each mounting position is provided with a positioning hole, and a matching pin is provided at the corresponding position on the damper component, and the pin on the damper component is inserted into the positioning hole on the mounting position to ensure the correct installation of the damper component. The evenly distributed mounting positions and standardized design make the maintenance and replacement of the damper components more convenient.

[0030] The air valve assembly is arranged in the limiting groove 7, and the air valve assembly includes a shaft sleeve 12, which is fixedly connected to the air valve body 1, and the shaft sleeve 12 corresponds to the positioning hole in the limiting groove 7. The shaft sleeve 12 is used to support the valve stem 5 to prevent the valve stem 5 from shaking left and right. A silicone layer is arranged on the edge of the air valve plate 4, and the silicone layer provides good sealing to prevent air leakage, thereby improving the overall air tightness of the air valve and further accurately controlling the air flow direction. The air valve plate 4 is connected to the valve stem 5, and the rod body of the valve stem 5 passes through the shaft sleeve 12, and the air valve plate 4 is installed on the positioning hole in the limiting groove 7. Ensure that the air valve plate 4 will not interfere with each other when opening and closing. The head of the valve stem 5 is a circular toothed structure, and the head of the valve stem 5 is meshed and connected with the translation rack 3. The horizontal movement of the translation rack 3 can accurately control the rotation of the valve stem 5. The air valve plate 4 rotates synchronously with the valve stem 5. The air valve plate 4 is initially staggered at 180 degrees and 90 degrees.

[0031] The air valve body 1 is provided with a plurality of openings, namely, through hole A, through hole B, through hole C, through hole D, and through hole E. Through hole A and through hole B are provided on the upper end surface of the air valve body 1, and through hole C, through hole D, and through hole E are provided on the lower end surface of the air valve body 1. Dry air and wet air are exchanged through the above-mentioned plurality of channels. Through the cooperation of the five-position reversing air valve with the dry channel and the wet channel, dry air can always enter the air conditioning system and the wet channel can be regenerated.

[0032] In the initial state, both the dry channel and the wet channel are equipped with desiccants. The wet air sucked in from the outside can be dried by passing through the dry channel. Then the dry channel becomes a wet channel after absorbing moisture. Figure 1 As shown, the wind sucked in from the outside enters the air duct 6 through the through hole D, and then goes to the first desiccant channel through the through hole B. At this time, the wet air is dried through the first desiccant channel; the hot air from the solar collector enters the air duct 6 through the through hole A, and then goes to the second desiccant channel through the through hole C, thereby realizing the regeneration of the second desiccant channel through the hot air.

[0033] Then, by controlling the moving assembly, the translation rack 3 moves leftward, driving the valve stem 5 in the air valve assembly to rotate clockwise, so that the corresponding air valve plate 4 can rotate 90 degrees clockwise, thereby realizing the reversal of the reversing air valve. Figure 2 As shown, the hot air from the solar collector enters the air duct 6 through the through hole B, and then goes to the first desiccant channel through the through hole E to achieve the regeneration of the first desiccant channel; the air inhaled from the outside enters the air duct 6 through the through hole D, and then goes to the second desiccant channel through the through hole A. At this time, the wet air is dried through the second desiccant channel. By switching in this way, dry air can always enter the air conditioning system and the wet channel can be regenerated.

[0034] When one of the desiccant channels in the drying assembly has been drying the mixed air for a certain period of time, the five-position reversing air valve is controlled to allow the other desiccant channel to continue drying the mixed air. At the same time, air flows into the previous desiccant channel to regenerate the previous desiccant channel, thereby achieving uninterrupted dehumidification of the mixed air.

[0035] It is worth noting that the contents not elaborated in detail in the present invention are all prior art and are well known to those skilled in the art.

[0036] Therefore, the present invention adopts the above-mentioned five-position reversing air valve, which has a compact design, occupies a small space, is easy to install and integrate into the existing system, and ensures precise linkage between the air valve plates through an integrated moving component, and accurately controls the air flow direction according to different needs, reduces manual operation, and improves the system's degree of automation and operating efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
