The embodiments of the present application disclose an integrated intelligent control valve device and a water leakage detection system.
[0031] The core of the present application is to provide an integrated intelligent control valve device and a water leakage detection system.
[0032] Please refer to Figure 1 and Figure 2 .
[0033] The integrated intelligent control valve device provided by the present application comprises an adjusting ball valve 1, an ultrasonic energy meter 2 is arranged at the inlet of the adjusting ball valve 1, an intelligent execution controller 3 is arranged on one side of the outlet of the adjusting ball valve 1, a water leakage detection sensor 4 is arranged on one side of the valve body of the adjusting ball valve 1, and the water leakage detection sensor 4 is electrically connected with the intelligent execution controller 3.
[0034] Specifically, the ultrasonic energy meter 2 is installed at the inlet of the regulating ball valve 1 to monitor the fluid flow through the valve in real time and transmit the flow data to the intelligent execution controller 3. The intelligent execution controller 3 serves as the core processing unit of the entire device, which not only receives the flow information from the ultrasonic energy meter 2, but also receives the signal from the water leakage detection sensor 4. The water leakage detection sensor 4 is arranged on one side of the valve body of the regulating ball valve 1 and can accurately monitor whether there is water leakage around the valve body. Once water leakage is detected, the water leakage detection sensor 4 will immediately convert this information into an electrical signal and transmit it to the intelligent execution controller 3. Upon receiving the water leakage signal, the intelligent execution controller 3 will quickly start the preset emergency processing program. According to the severity of the water leakage and the preset logical judgment, the intelligent execution controller 3 will send control instructions to the regulating ball valve 1 and drive the valve (including but not limited to full opening of the valve, full closing of the valve, prohibition of valve action, and different operation modes such as valve operation according to the original logic). Avoid additional losses caused by secondary operations on different systems.
[0035] The integrated intelligent control valve device effectively solves the problems caused by the separation of water leakage detection and valve control in the prior art. First, by directly electrically connecting the water leakage detection sensor 4 and the intelligent execution controller 3, the water leakage detection and valve control are tightly integrated, simplifying the system architecture and reducing the wiring cost and installation difficulty. Second, the fast response capability and autonomous decision-making function of the intelligent execution controller 3 enable the device to quickly and automatically take emergency measures when water leakage is detected, significantly improving the intelligence and fast response capability of the system. In addition, the device also has a flow monitoring function, which can monitor the fluid flow in real time, providing strong support for the optimized operation and energy-saving management of the system.
[0036] The integrated intelligent control valve device provided by the present application will be described in more detail below in conjunction with the drawings and specific embodiments.
[0037] In one specific embodiment, referring to Figure 2 , Figure 2 is a schematic diagram of the electrical connection of the intelligent execution controller 3 and the water leakage detection sensor 4. The water leakage detection sensor 4 includes at least two moisture sensing probes, which are linearly arranged and fixedly arranged at the bottom of the valve body of the regulating ball valve 1.
[0038] Specifically, the two humidity sensors are composed of humidity sensing elements, which can detect the slight changes in the surrounding humidity in real time. When water leaks from the bottom of the valve body of the regulating ball valve 1, the moisture will quickly change the humidity environment around the probe, and the humidity sensor will immediately convert this humidity change into an electrical signal. After preliminary processing, these electrical signals are sent to the intelligent execution controller 3. Through the optimization of the design of the water leakage detection sensor 4 and the function of the intelligent execution controller 3, accurate monitoring and rapid response to water leakage are achieved, and multi-point water leakage detection of the regulating ball valve 1 is realized, effectively improving the safety and reliability of the heating, ventilation and air conditioning control system.
[0039] On the basis of any one of the above embodiments, the intelligent execution controller 3 includes an execution assembly (not shown in the figure) and a controller (not shown in the figure), the execution assembly is connected with the valve stem of the regulating ball valve 1 and is used to control the rotation angle of the valve stem; the controller is connected with the execution assembly, the ultrasonic energy meter and the water leakage detection sensor 4, and is used to receive the signals from the upper computer and control the operation of the execution assembly according to the flow calculated by the ultrasonic energy meter 2, the temperature difference and the cold heat, and the water leakage condition reacted by the water leakage detection sensor 4.
[0040] Specifically, the execution assembly is usually composed of a high-precision electric actuator, which can accurately control the rotation angle of the valve stem of the regulating ball valve 1 according to the instructions from the controller, thereby realizing fine adjustment of the valve opening. On the one hand, the controller is connected with the upper computer through the communication interface to receive the control signals and parameter settings from the upper computer; on the other hand, it maintains real-time communication with the ultrasonic energy meter 2 and the water leakage detection sensor 4 to continuously obtain data such as flow, temperature difference, cold heat and water leakage condition. After receiving these data, the controller will use the built-in advanced algorithm and logic judgment program to comprehensively analyze the current working condition. For example, it will evaluate the energy efficiency and operating status of the system according to the flow and cold heat calculated by the ultrasonic energy meter 2; at the same time, combined with the water leakage condition feedback by the water leakage detection sensor 4, it will judge whether there is a safety hazard or emergency measures need to be taken.
[0041] Based on these analysis results, the controller will issue control instructions to the execution assembly to adjust the opening of the valve or close the valve to achieve effective control of the fluid flow or respond to emergency situations such as water leakage. The controller can also have functions such as data recording, fault diagnosis and remote communication, which can record system operation data, discover and report potential faults in time, and interact with the central monitoring platform through the remote communication interface to realize remote monitoring and management.
[0042] On the basis of any one of the above embodiments, with reference to Figure 3, the integrated intelligent control valve device can further include a health monitoring module 5 (not shown in the figure) electrically connected with the intelligent execution controller 3, for detecting the functional status of the ultrasonic energy meter 2, the regulating ball valve 1 and the water leakage detection sensor 4 according to a preset time interval.
[0043] Specifically, the health monitoring module 5 assesses the operating conditions of each component by periodically sending detection signals to each component and receiving status feedback from each component. This process does not require human intervention, ensuring that the system can continuously and automatically monitor the health status of key components.

[0045] Specifically, when the health monitoring module 5 detects that the functional status of any one component is abnormal, the fault warning device 51 will be triggered immediately. It will package detailed fault information (including fault type, occurrence time, possible impact range, etc.) into alarm information according to a preset communication protocol, and send it to external devices such as a central monitoring platform, a manager's mobile phone or tablet computer, etc. through wired or wireless means. In this way, relevant personnel can respond quickly and take necessary maintenance or emergency measures to prevent the problem from worsening.
[0046] Further, the health monitoring module 5 is built-in with a diagnostic module 52 for evaluating the performance indicators of the ultrasonic energy meter 2, the regulating ball valve 1 and the water leakage detection sensor 4 and generating corresponding health reports.
[0047] Specifically, the diagnostic module 52 will use a series of advanced algorithms and models to deeply analyze the collected operating data of each component. It will not only check whether each component is within the normal working range, but also assess the long-term trend of its performance indicators and predict potential failure risks. Based on these analysis results, the diagnostic module 52 will generate detailed health reports containing the current status of each component, historical performance data, fault warning information and maintenance recommendations, etc. These reports have important reference value for preventive maintenance, performance optimization and troubleshooting of the device.
[0048] It should be noted that the health monitoring module 5 also has the ability of self-learning and optimization. It will continuously adjust and improve the diagnostic algorithms and warning thresholds based on historical data and actual operating experience to improve the accuracy and reliability of monitoring. At the same time, it will closely cooperate with the intelligent execution controller 3 and other system components to form an efficient and intelligent control system.

[0050] Specifically, when the integrated intelligent control valve device detects water leakage, it will immediately send the water leakage detection result (including the water leakage position, the water leakage degree, the occurrence time and other key information) to the remote management terminal 6 through the wireless communication module 7. After receiving these data, the remote management terminal 6 will use its data processing unit 61 to quickly analyze and process the data, extract valuable information, and present it to the management personnel in an intuitive and easy-to-understand way through the user interaction interface 62. At the same time, according to the preset logic judgment, control instructions are sent to the intelligent execution controller 3 and the valve operation (including but not limited to valve full opening, valve full closing, valve prohibition action and valve operation according to the original logic operation and other different operation modes) is controlled. Avoid additional losses caused by uploading different systems for secondary operation.
[0051] The water leakage detection system effectively solves the problems of slow response, inability to remotely monitor and weak data processing capacity in the detection method of the prior art. Through the close combination of the integrated intelligent control valve device and the remote management terminal 6, the system can realize rapid detection, real-time transmission and remote monitoring of water leakage, and improve the efficiency and accuracy of water leakage treatment.
