Description

Technical Field

[0001] This utility model relates to the field of ultrasonic water meter manufacturing technology, specifically to an adjustable bubble generating device. Background Technology

[0002] Driven by the need to improve traditional water meter technology and the pursuit of more efficient, accurate, and sustainable water resource management, ultrasonic water meters have been widely used and promoted globally due to their advantages such as higher accuracy, stronger stability, wider rangeability, greater adaptability, and lower failure rate. The working principle of ultrasonic water meters is to use the propagation characteristics of ultrasonic waves in water to measure flow rate non-contactly. However, in practical applications, air bubbles in the pipeline pose a significant challenge to the measurement accuracy of ultrasonic water meters. The presence of air bubbles causes attenuation, scattering, and multipath propagation of ultrasonic signals, severely affecting measurement accuracy, especially in industrial wastewater, groundwater extraction, and water supply networks, where the air bubble problem is particularly prominent. Solving this problem is of great significance for improving the reliability and applicability of ultrasonic water meters.

[0003] To reduce the impact of bubbles on metering accuracy, improvements can be made in structure, hardware, and algorithms. It is also necessary to build an experimental platform to simulate water environments with different bubble contents and distributions to verify the effectiveness and reliability of the aforementioned technologies. In production practice, some use air pumps to blow air in for simulation, which is low-cost but produces poor simulation results, makes it difficult to precisely control bubble flow rate, and cannot control bubble size and quantity. Currently, the main bubble generating devices on the market are ordinary bubble generating devices, microbubble generating devices, and nanobubble generating devices, but they also have the following problems: 1) They cannot accurately control bubble size and quantity, making it difficult to simulate the real working environment of water meters; 2) They are costly, large in size, and difficult to match with experimental platforms. Utility Model Content

[0004] This utility model discloses an adjustable bubble generator, which solves the technical problems of poor simulation effect when using gas pumps and difficulty in controlling bubble size and quantity in existing bubble generators. It features a reasonable structure, adjustable bubble generation rate, bubble size and quantity, good simulation effect, and low cost. The technical solution adopted is as follows:

[0005] An adjustable bubble generator includes a filter, a flow regulating valve, and a shut-off valve arranged sequentially along the airflow direction. The filter, flow regulating valve, and shut-off valve are connected by a pipeline and can jointly form a gas passage for gas to pass through. The filter can filter the flowing gas, the flow regulating valve is used to regulate the flow rate of the flowing gas, and the shut-off valve is used to shut off the gas passage. The first end of the gas passage can be connected to an external gas source, and the second end of the gas passage can be connected to experimental equipment to introduce bubbles into the fluid.

[0006] Based on the above technical solution, a gas flow meter is also installed in the gas passage between the filter and the flow regulating valve. The gas flow meter is used to monitor the gas flow in real time to cooperate with the flow regulating valve for flow regulation.

[0007] Based on the above technical solution, the filter includes an oil-water separator, which is used to stabilize the gas pressure flowing through the gas and filter out moisture, oil and particulate matter in the gas.

[0008] Based on the above technical solution, a check valve is also provided in the gas passage between the flow regulating valve and the shut-off valve to allow unidirectional gas flow.

[0009] Based on the above technical solution, the connecting pipe section that forms a gas passage between the external gas source, filter, flow regulating valve, check valve, shut-off valve and experimental equipment is a flexible hose.

[0010] Based on the above technical solution, the connecting pipe section is connected to an external air source, filter, flow regulating valve, check valve and shut-off valve through a quick-connect plug.

[0011] Based on the above technical solution, an external controller is also included, and the flow regulating valve, check valve and shut-off valve are electrically connected to the external controller.

[0012] Based on the above technical solution, the external air source includes an air pump, which is electrically connected to an external controller and is used to pump outside air into the gas passage.

[0013] Beneficial effects

[0014] This invention features a rationally designed structure. The first end of the gas passage can be connected to an external gas source, while the second end can be connected to experimental equipment to introduce bubbles into the fluid. The included flow control valve allows for flexible adjustment of the gas flow rate, thereby controlling the gas velocity and consequently regulating the size and quantity of bubbles to meet different experimental needs. Furthermore, a flow meter is installed before the flow control valve. This allows for precise acquisition of real-time gas flow values, facilitating accurate adjustment of the valve and gas velocity, thus better regulating bubble size and quantity. Additionally, precise control of the gas flow rate ensures a consistent bubble environment throughout the experiment, improving the reliability of the experimental results.

[0015] In this invention, the filter can be an oil-water separator, used to stabilize the gas pressure flowing through the gas and filter out moisture, oil, and particulate matter from the gas. On the one hand, this makes the gas pressure entering the flow meter more stable, which is beneficial to improving measurement accuracy and thus enabling precise control of the flow regulating valve. On the other hand, stabilizing the airflow in the gas passage also makes the generated bubbles uniform in size and speed, which can better simulate the bubble distribution state in the environment and achieve good simulation results. Furthermore, the filter ensures that the gas entering the gas passage is dry and free of impurities, guaranteeing the purity of the final generated bubbles, which helps to reduce experimental errors and protect downstream equipment.

[0016] The backflow preventer valve of this invention prevents insufficient air pressure and fluid backflow caused by improper operation or equipment failure, effectively protecting the bubble generator and other equipment from damage and improving operational safety. Furthermore, the shut-off valve not only functions as a switch for convenient and quick control of bubble supply start and stop, but also promptly cuts off fluid flow in the event of backflow.

[0017] In addition, the connecting pipe section in this application is a flexible hose, which is convenient for layout and can also buffer airflow. The connecting pipe section is connected to adjacent equipment through quick-connect plugs, which has good compatibility, is easy to disassemble and assemble, and is more flexible in use.

[0025] like Figure 1An adjustable bubble generator is shown, comprising a filter 2, a gas flow meter 3, a flow regulating valve 4, a check valve 5, and a shut-off valve 6 arranged sequentially along the airflow direction.

[0026] like Figure 1 As shown, filter 2, gas flow meter 3, flow regulating valve 4, check valve 5, and shut-off valve 6 are connected by connecting pipe section 7. Connecting pipe section 7 is made of flexible tubing for easy installation and to buffer airflow. Connecting pipe section 7 connects to adjacent equipment via quick-connect plugs 8, ensuring good compatibility, easy assembly and disassembly, and greater flexibility in use. This forms a gas passage through which gas flows. The first end of the gas passage is connected to external gas source 1 via connecting pipe section 7, and the second end of the gas passage is connected to the experimental equipment via connecting pipe section 7 to introduce air bubbles into the fluid.

[0027] In this embodiment, filter 2 filters the flowing gas. Filter 2 includes an oil-water separator, used to stabilize the gas pressure and remove moisture, oil, and particulate matter from the gas. This ensures a more stable gas pressure entering the gas flow meter 3, improving measurement accuracy and enabling precise control of the flow regulating valve 4. Furthermore, stabilizing the airflow in the gas path also results in uniform bubble size and velocity, better simulating the bubble distribution in the environment and providing a better simulation effect. Additionally, the filter 2 ensures the gas entering the gas path is dry and free of impurities, guaranteeing the purity of the final generated bubbles and preventing the introduction of new impurities, thus reducing experimental errors and protecting downstream equipment. The oil-water separator is existing technology, and those skilled in the art can select it according to their needs; further details are omitted here.

[0028] The gas flow meter 3 is used to monitor the flow rate of the gas. The gas flow meter 3 is existing technology and will not be described in detail here.

[0029] The flow regulating valve 4 is used to adjust the flow rate of the gas. The gas flow meter 3 and the flow regulating valve 4 work together. By monitoring the gas flow meter 3 and adjusting the flow regulating valve 4, the flow rate of the gas in the gas passage can be precisely controlled, thereby adjusting the size and number of bubbles produced to adapt to different experimental needs. Furthermore, when it is necessary to ensure that the size and number of bubbles produced are consistent each time in the experiment, the flow regulating valve 4 is controlled so that the reading of the gas flow meter 3 is approximately the same in each experiment. This ensures that the size and number of bubbles produced in each experiment are basically consistent, thus creating a roughly identical experimental environment and improving the detection accuracy of the experimental platform. The flow regulating valve 4 is existing technology, and those skilled in the art can select it according to their needs.

[0030] Check valve 5 is used to allow unidirectional gas flow, preventing insufficient gas pressure and fluid backflow caused by improper operation or equipment failure. It effectively protects the bubble generator and other equipment from damage, thus improving operational safety. Check valve 5 is existing technology; those skilled in the art can select it according to their needs.

[0031] The shut-off valve 6 not only functions as a switch, conveniently and quickly controlling the start and stop of bubble supply, but also promptly cuts off the fluid in case of backflow, making it easy to use. The shut-off valve 6 is existing technology, and those skilled in the art can select it according to their needs.

[0032] External air source 1 includes an air pump, which is used to pump outside air into the gas passage. It is low-cost and easy to use.

[0033] It also includes an external controller. The air pump, filter 2, gas flow meter 3, flow regulating valve 4, check valve 5 and shut-off valve 6 are electrically connected to the external controller to facilitate automated control.
