Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning conversion valves, and particularly to a disc-type air-conditioning refrigeration and heat conversion valve. Background Art

[0002] In traditional air-conditioning systems, refrigeration and heat conversion valves usually adopt an internal linear drive structure. The internal drive components of such valve bodies are in direct contact with the valve bodies, resulting in a relatively complex structure, large space occupation, and problems such as mechanical component wear and failure during long-term use. In addition, due to the linear drive structure, the switching operation of the valve body may generate vibration and impact, which not only affect the stability of the system, but also may affect the accuracy and response speed of the system.

[0003] Traditional linear drive conversion valves require a relatively complex mechanical structure, and due to the close fit between the drive components and the valve bodies, it causes waste of space within the system. In practical applications, the volume and weight of the system often pose problems in design and installation. Moreover, the vibration and impact generated during the switching process of the valve body may make it difficult to precisely adjust the fluid channels, thereby affecting the refrigeration and heating effects and unable to provide more precise temperature control requirements.

[0004] In addition, the control accuracy of traditional internally driven valve bodies is relatively limited, and it is often unable to accurately adjust the working state of the valve body under different environmental conditions, resulting in difficulty in quickly responding to external load changes during system operation, thereby affecting the overall efficiency and comfort of the air-conditioning system.

[0005] Therefore, there is an urgent need for a new design of air-conditioning refrigeration and heat conversion valves that can overcome problems such as space occupation, vibration, and precision control existing in traditional linear drive systems, and improve the working efficiency, precision, and reliability of the valve bodies to achieve a more concise, compact, precise, and efficient air-conditioning conversion system. Summary of the Invention

[0006] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] To this end, the technical solution adopted by the present invention is as follows: A disc-type air-conditioning refrigeration and heat conversion valve, adopting an annular electromagnetic drive structure and an external drive structure, aims to overcome problems such as complex drive components, large space occupation, insufficient precision control, and slow system response speed existing in the prior art. The technical solution of the present invention can improve the operating efficiency, precision, and reliability of the air-conditioning system, and has the advantages of a compact structure, easy installation and maintenance.

[0008] The disc-type air-conditioning refrigeration and heat conversion valve of the present invention is characterized by comprising a main valve body and a drive assembly, wherein: On the upper and lower sides of the main valve body, there are concentrically arranged intake ends and sealing slides respectively. Inside the main valve body, there is a first connecting pipe cavity and a second connecting pipe cavity. The bottom surface of the main valve body is rotatably installed with an exhaust end, and the bottom surface of the sealing slide is slidably installed with a first slide pipe end and a second slide pipe end. Through the structural design, the fluid switching between different pipes is realized. The ports of the first connecting pipe cavity and the second connecting pipe cavity are respectively hermetically connected to the first slide pipe end and the second slide pipe end.

[0009] The driving assembly includes a driving ring seat, fixed ears, a yoke member, and a permanent magnet ring group arranged on the surface of the driving ring seat. The fixed ears and the yoke member are fixed on the surface of the main valve body, and guide wheels that slidably abut against the inner side of the driving ring seat are provided on the surface of the fixed ears. A coil group is provided on the surface of the yoke member, and the end of the coil group is electrically connected to an excitation control module to generate an alternating magnetic field on the surface of the yoke member, which acts on the permanent magnet ring group to drive the main valve body to achieve a rotational motion.

[0010] Through the above design, the annular electromagnetic driving structure in the present invention can provide a smooth rotational motion, avoiding the vibration and impact that may occur in the traditional built-in linear driving structure, thereby improving the switching accuracy of the valve body. When the main valve body rotates, the fluid channel can be accurately adjusted to achieve fast and precise switching between the cooling and heating modes in the air conditioning system, improving the adjustment efficiency and response speed of the air conditioning system.

[0011] The beneficial effects achieved by the present invention are as follows: 1. In the present invention, an annular electromagnetic driving structure is adopted. The external driving structure can separate the driving assembly from the valve body, avoiding direct contact between the driving assembly and the inside of the valve body, and reducing the internal complex mechanical structure. Such a design enables the internal structure of the main valve body to remain simple, reduces the occupied space inside the valve body, improves the compactness of the overall system, and facilitates installation and maintenance.

[0012] 2. In the present invention, compared with the traditional built-in linear driving switching valve, the annular electromagnetic driving of the yoke member and the permanent magnet ring group provides a continuous and smooth rotational motion, without generating the vibration and impact that may occur in the linear driving structure, enabling the disc-shaped valve body to more accurately adjust the fluid channel during rotation, thereby achieving more precise switching between cooling and heating.

[0013] 3. In the present invention, the combination of the external driving assembly using annular electromagnetic driving enables the working state of the switching valve to be more accurately adjusted to meet the requirements in different environments. Under different external load conditions, the system can more accurately adjust the temperature control requirements and provide a more comfortable air environment. Description of the Drawings

[0016] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0017] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0018] The following combines the attached Figures 1 to 6 Describe a disc-type air-conditioning refrigeration and heat conversion valve provided by some embodiments of the present invention.

[0019] To better clarify the implementation manners of the present invention, the specific implementation of the present invention will be described in detail below with reference to the accompanying drawings. When implementing the present invention, unless otherwise clearly stated, each component in the present invention can be adjusted and optimized as needed.

[0020] Embodiment 1: Disc-type air-conditioning refrigeration and heat conversion valve As Figures 1 to 6 shown, the disc-type air-conditioning refrigeration and heat conversion valve in this embodiment mainly consists of a main valve body 100, a drive assembly 200 and several connecting components. The working principle is to drive the main valve body 100 to rotate through an external annular electromagnetic drive structure, thereby controlling the switching of the fluid passage and realizing the conversion between the refrigeration and heating modes.

[0021] 1. Main valve body 100: Intake end 101: This component is connected to the exhaust pipe of the compressor. The high-pressure gas provided by the compressor enters the main valve body 100 through the intake end 101.

[0022] Sealing slideway 104: Through sliding fit, this part ensures that during the rotation of the main valve body 100, the fluid can be guided to different pipe systems as needed, while avoiding leakage and unnecessary fluid flow.

[0023] First communication lumen 102 and second communication lumen 103: These two lumens are respectively connected to the first slide pipe end 120 and the second slide pipe end 130. By rotating the valve body, the fluid passage is adjusted, thereby realizing the switching between refrigeration and heating.

[0024] Exhaust end 110: It is connected to the suction pipe of the compressor and adjusts the direction of the air flow entering the evaporator or condenser to realize the reverse switching of the system.

[0025] 2. Driving assembly 200: Driving ring seat 210: This component drives the main valve body 100 by connecting the fixed ear 220 and the yoke part 230. Its function is to drive the valve body to rotate precisely through the magnetic field generated by the annular electromagnetic drive.

[0026] Fixed ear 220 and yoke part 230: These two components are fixed on both sides of the main valve body 100, and a guide wheel 221 that slidably abuts against the inner side of the driving ring seat 210 is provided on the fixed ear 220. Through sliding fit, the guide wheel provides stable support and drive to ensure the smooth operation of the system.

[0027] Permanent magnet ring group 240: It is composed of multiple permanent magnet blocks. Under the action of the alternating magnetic field generated by the yoke part 230, these permanent magnet blocks push the main valve body 100 to rotate and control the flow direction of the fluid. The opposite magnetic poles of the permanent magnet blocks are arranged to ensure stable and precise switching of the fluid direction during the driving process of the system.

[0028] 3. Working principle: Annular electromagnetic drive: When the system is turned on, the control module changes the current direction of the coil group on the surface of the yoke part 230 through current, generating an alternating magnetic field. This magnetic field acts on the permanent magnet ring group 240, causing the main valve body 100 to rotate stably, thereby precisely adjusting the fluid flow direction.

[0029] Refrigeration mode: In the refrigeration mode, when the main valve body 100 rotates to a certain position, the first communication lumen 102 is connected to the first slide pipe end 120, and the second communication lumen 103 is connected to the second slide pipe end 130, forming a fluid passage. The condenser and the evaporator start to work in the normal way, and the system completes the refrigeration process.

[0030] Heating mode: When switched to the heating mode, the main valve body 100 rotates to another position, changing the flow direction of the fluid. The second communication pipe cavity 103 is connected to the first sliding pipe end 120, and the first communication pipe cavity 102 is connected to the second sliding pipe end 130. The fluid releases heat through the evaporator and enters the condenser, and the system starts to work to provide hot air.

[0031] 4. Sealing design: Sealing slip ring 104: Used to maintain the sealing effect of the ports of the first communication pipe cavity 102 and the second communication pipe cavity 103 during the rotation of the main valve body 100.

[0032] Dynamic sealing assembly: Installed between the exhaust end 110 and the port of the second communication pipe cavity 103 to prevent leakage during the rotation of the valve body.

[0033] 5. Regulation and control: This disc type conversion valve can automatically adjust the position of the valve body according to the actual temperature control requirements during the operation of the system. Through the cooperation of the annular electromagnetic drive and the permanent magnet ring group, the system can respond to the changes of the external load, accurately adjust the flow direction and channels of the fluid, and ensure the stable operation of the air conditioning system.

[0034] Embodiment 2: Electromagnetic control module and control system The present invention also relates to a control system used in conjunction with the disc type air conditioning refrigeration and heat conversion valve. This system realizes precise control of the drive assembly 200 through an electronic control module, and can automatically adjust the position of the valve body according to the operating state of the air conditioning system, so as to quickly respond to the switching requirements of the refrigeration or heating mode.
