Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioning technical field, concretely relates to a kind of air conditioner intelligent control valve. BACKGROUND

[0002] In air conditioning system, control valve as the key component of adjusting refrigerant flow and pressure, plays a vital role to the running efficiency and stability of system. Traditional air conditioning control valve is mostly manually or simply mechanically adjusted, and its adjustment precision and response speed are limited, which is difficult to meet the demand of modern air conditioning system for high precision and fast response.

[0003] With the continuous development of intelligent control technology, various sensors and electric control elements are introduced into air conditioning system to realize accurate control of refrigerant flow and pressure. However, the existing intelligent control valve often has problems such as high complexity, loose cooperation between components, and inflexible adjustment. For example, some intelligent control valves use multiple independent transmission mechanisms to realize the opening and closing and adjustment of valve plug, which not only increases the size and weight of the valve, but also may cause energy loss and precision decline in the transmission process. Moreover, the existing intelligent control valve also has certain limitations in pressure sensing and adjustment. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide an air conditioner intelligent control valve.

[0007] In this invention, as an optional embodiment, the housing includes an upper shell and a lower shell, which are interlocked. The specific design of the edges of the upper and lower shells allows them to be tightly joined together without the need for additional fasteners, simplifying the assembly process and improving production efficiency. Furthermore, the interlocking connection has a certain degree of self-locking, ensuring that the upper and lower shells will not easily separate during normal use.

[0008] In this utility model, as an optional embodiment, the inner bore of the shaft gear is a square inner bore, and the shape of one end of the valve plug matches the shape of the inner bore of the shaft gear. The square inner bore of the shaft gear forms a tight fit with one end of the valve plug, ensuring stability and accuracy during transmission. The valve plug is a component in the control valve used to regulate fluid flow. The shape matching ensures that the valve plug can be firmly inserted into the inner bore of the shaft gear and moves together with it when the shaft gear rotates, thereby achieving precise control of the valve plug, providing better transmission stability, and preventing the valve plug from slipping or deflecting during transmission.

[0009] In this invention, as an optional embodiment, a visual image acquisition device is also installed inside the refrigeration pipe. This device is wirelessly connected to a microcontroller control circuit board. The visual image acquisition device is used to acquire the relative position information of the valve plug and the valve orifice, and then sends this information to the microcontroller control circuit board.

Its main function is to acquire the relative position information of the valve plug and the valve orifice. Through image processing, the position and state of the valve plug, as well as its alignment with the valve orifice, can be accurately identified.

[0010] In this invention, as an optional embodiment, a temperature sensor is also installed inside the refrigeration pipe. The temperature sensor is wirelessly connected to a microcontroller control circuit board. The temperature sensor collects ambient temperature information from the refrigeration pipe and sends this information to the microcontroller control circuit board, which then adjusts the rotation angle of the shaft gear via a drive motor. A temperature sensor is a device that can sense and convert temperature signals into electrical signals. Installing a temperature sensor inside the refrigeration pipe allows for real-time monitoring of the ambient temperature within the pipe. By sensing temperature changes within the pipe, the operating status and efficiency of the refrigeration system are directly reflected. The microcontroller control circuit board receives and processes the temperature information from the temperature sensor and then adjusts the rotation angle of the drive motor according to a preset control strategy, thereby changing the position of the valve plug to regulate the refrigerant flow and temperature.

[0011] In this invention, as an optional embodiment, the housing is further provided with an operating knob, which is connected to a transmission belt. The operating knob is a user interface component, typically mounted externally to the housing for easy manual operation. When the user rotates the operating knob, the rotational torque is transmitted to the shaft gear via the transmission belt, thereby driving the valve plug to move or change its position. This allows the user to manually control the movement of the valve plug in special circumstances, providing an intuitive and easy-to-use control method.

[0012] In this invention, as an optional embodiment, the valve plug is spherical on the side near the valve port. The spherical valve plug provides excellent sealing performance, flow characteristics, wear resistance, and ease of operation, making the control valve more precise, efficient, and reliable in regulating fluid flow.

By adding a pressure sensor to detect real-time pressure, and then detecting the opening degree between the valve plug and the valve port, precise flow regulation and control are achieved.

[0024] Please refer to Figures 1-4As shown in the figure, this application provides an intelligent control valve for an air conditioner, including a housing 1 and a refrigeration pipe 10. The refrigeration pipe 10 is connected to one side of the housing 1. A valve plug 2, a shaft gear 3, a transmission gear belt 4, a telescopic spring 5, and a fixing plate 6 are installed inside the housing 1. One end of the shaft gear 3 is meshed with one end of the transmission gear belt 4, and the other end of the transmission gear contacts one end of the telescopic spring 5. The other end of the telescopic spring 5 abuts against the fixing plate 6. A valve port is provided on the housing 1. One end of the valve plug 2 is embedded in the inner hole of the shaft gear 3, and the other end of the valve plug 2 extends to... The valve port is connected to the refrigeration pipe 10. The housing 1 is also equipped with a pressure sensor 7, a microcontroller control circuit board 8, and a drive motor 9. The pressure sensor 7 and the drive motor 9 are both connected to the microcontroller control circuit board 8. One end of the drive motor 9 is connected to the shaft gear 3. The pressure sensor 7 is mounted on the fixed plate 6 to collect the pressure signal applied to the fixed plate 6 by the telescopic spring 5 and transmit the pressure signal to the microcontroller control circuit board 8 so that the microcontroller control circuit board 8 can adjust the rotation angle of the shaft gear 3 through the drive motor 9.

[0025] In the above description, the housing 1 serves as the main structure of the control valve, providing installation and protection space for internal components. The refrigeration pipe 10 connects to one side of the housing 1, communicating with the valve port and responsible for refrigerant flow. The valve plug 2 is a key component controlling refrigerant flow; one end is embedded in the inner hole of the shaft gear 3, and the other end extends to the valve port, opening or closing the valve port by movement. The shaft gear 3 meshes with one end of the transmission belt 4, which rotates due to the rotation of the drive motor 9, thus driving the valve plug 2 to move. The transmission belt 4 serves as the transmission medium, connecting the shaft gear 3 and the telescopic spring 5, transmitting the rotational motion. One end of the telescopic spring 5 contacts the transmission belt 4, and the other end abuts against the fixing plate 6, providing the elastic force for the valve plug 2 to return to its initial position without external force. The fixing plate 6 is used to fix one end of the telescopic spring 5, providing support for the spring. The valve port is located on the housing 1, communicating with the refrigeration pipe 10, and serves as the channel for refrigerant flow. The movement of the valve plug 2 controls the opening and closing degree of the valve port, thereby regulating the refrigerant flow rate.

[0026] In this embodiment, when the air conditioning system is running, the pressure sensor 7 monitors the pressure applied to the fixed plate 6 by the telescopic spring 5 in real time and transmits the signal to the microcontroller control circuit board 8. The microcontroller control circuit board 8 calculates the required position of the valve plug 2 based on the received pressure signal and a preset control strategy. The drive motor 9 drives the shaft gear 3 to rotate according to the instructions from the microcontroller control circuit board 8. The rotation of the shaft gear 3 is transmitted to the valve plug 2 via the transmission belt 4, causing it to move to the calculated position, thereby adjusting the opening and closing degree of the valve port and controlling the refrigerant flow. The telescopic spring 5 provides the necessary elasticity during the movement of the valve plug 2, ensuring that the valve plug 2 can move accurately and stably to the designated position, and resets the valve plug 2 when the external force is removed.

[0027] Furthermore, the housing 1 includes an upper shell 11 and a lower shell 12, which are engaged together. The specific design of the edges of the upper shell 11 and lower shell 12 allows them to fit together tightly without the need for additional fasteners, simplifying the assembly process and improving production efficiency. The engaging connection also has a certain degree of self-locking, ensuring that the upper shell 11 and lower shell 12 will not easily separate during normal use.

[0028] The shaft gear 3 is a key component inside the control valve. Connected to the drive motor 9, it converts the motor's rotational motion into the linear or rotational motion of the valve plug 2. The shaft gear 3 has a square inner bore, and the shape of one end of the valve plug 2 matches the shape of the shaft gear 3's inner bore. The square inner bore of the shaft gear 3 creates a tight fit with one end of the valve plug 2, ensuring stability and accuracy during transmission. The valve plug 2 is the component in the control valve used to regulate fluid flow. The shape match ensures that the valve plug 2 can be firmly inserted into the inner bore of the shaft gear 3 and moves along with it when the shaft gear 3 rotates, thereby achieving precise control of the valve plug 2, providing better transmission stability, and preventing the valve plug 2 from slipping or deflecting during transmission.

[0029] A visual image acquisition device is also installed inside the refrigeration pipe. This device is wirelessly connected to a microcontroller control circuit board 8. The visual image acquisition device is used to acquire the relative position information between the valve plug 2 and the valve port, and then sends this information to the microcontroller control circuit board 8. The visual image acquisition device is a device capable of capturing and converting visual images into digital signals. Installing the visual image acquisition device inside the refrigeration pipe of the control valve allows for real-time monitoring of the relative position between the valve plug 2 and the valve port. The wireless connection between the visual image acquisition device and the microcontroller control circuit board 8 eliminates the wiring complexity and limitations of traditional wired connections. Its main function is to acquire the relative position information between the valve plug 2 and the valve port. Through image processing, the position, state, and alignment degree of the valve plug 2 with the valve port can be accurately identified. The acquired relative position information is wirelessly transmitted to the microcontroller control circuit board 8, which is the core control unit of the control valve. It receives and processes the position information from the visual image acquisition device and then adjusts the rotation angle or speed of the drive motor 9 according to a preset control strategy, thereby achieving precise control of the valve plug 2. By acquiring the relative position information between valve plug 2 and valve port in real time, the control system can adjust the position of valve plug 2 more accurately, improve control precision, and the vision image acquisition device provides direct visual feedback, enabling the system to detect and handle potential faults or anomalies in a timely manner, thereby enhancing the reliability of the system.

[0030] A temperature sensor is also installed inside the refrigeration pipe. This temperature sensor is wirelessly connected to a microcontroller control circuit board 8. The temperature sensor collects ambient temperature information from the refrigeration pipe and sends this information to the microcontroller control circuit board 8, which then adjusts the rotation angle of the shaft gear 3 via the drive motor 9. A temperature sensor is a device that can sense and convert temperature signals into electrical signals. Installing a temperature sensor inside the refrigeration pipe allows for real-time monitoring of the ambient temperature within the pipe. By sensing temperature changes within the pipe, the operating status and efficiency of the refrigeration system are directly reflected. The microcontroller control circuit board 8 receives and processes the temperature information from the temperature sensor and then adjusts the rotation angle of the drive motor 9 according to a preset control strategy, thereby changing the position of the valve plug 2 to regulate the refrigerant flow and temperature. The wireless connection between the temperature sensor and the microcontroller control circuit board 8 eliminates the wiring complexity and limitations associated with traditional wired connections. The collected ambient temperature information is wirelessly transmitted to the microcontroller control circuit board 8. The microcontroller control circuit board 8 receives and processes the temperature information from the temperature sensor, and then adjusts the rotation angle of the drive motor 9 according to the preset control strategy, thereby changing the position of the valve plug 2 to regulate the refrigerant flow and temperature. By collecting the ambient temperature information of the refrigeration pipeline in real time, the control system can more accurately determine the operating status of the refrigeration system and adjust the position of the valve plug 2 accordingly, improving control accuracy.

[0031] The housing 1 is also equipped with an operating knob, which is connected to the transmission belt 4. The operating knob is a component of the user interface, usually installed on the outside of the housing 1, for easy manual operation by the user. When the user rotates the operating knob, the rotational torque is transmitted to the shaft gear 3 through the transmission belt 4, thereby driving the valve plug 2 to move or change its position. This allows the user to control the movement of the valve plug 2 manually in special circumstances, providing an intuitive and easy-to-use control method.

[0032] The valve plug 2 is spherical on the side closest to the valve port. The spherical valve plug 2 provides excellent sealing performance, flow characteristics, wear resistance, and ease of operation, making the control valve more precise, efficient, and reliable in regulating fluid flow.
