Description

Technical Field

[0001] This utility model relates to the field of central air conditioning circulating pump retrofit technology, and in particular to a multifunctional flow metering device for energy-saving retrofit. Background Technology

[0002] Driven by the "dual carbon" goal, energy-saving renovations in the industrial and building sectors rely on accurate energy metering and energy efficiency assessments. Flow rate, as a core parameter of energy-carrying media such as water, steam, and refrigerant, directly affects system energy consumption analysis. In central air conditioning systems, a 5% deviation in chilled water flow rate can lead to a 10%-15% increase in pump energy consumption. The flow monitoring accuracy of industrial waste heat recovery networks is less than ±3%, which may cause a loss of more than 20% in heat recovery efficiency. During the renovation process, flow metering devices need to be installed on the pipelines. However, conventional pipelines may not have straight pipes, leaving no space for installing flow metering devices. At the same time, because the medium inside the pipeline does not flow in a straight line, the parameters measured by the flow metering device are not accurate enough, which will also affect the normal operation of the circulating pump. To solve the above problems, a new flow metering device needs to be designed. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multifunctional flow metering device for energy-saving renovation. It solves the problem of traditional flow meters having a single measurement dimension under complex working conditions, and solves the problem of valves being too close to the flow meter and the straight pipe sections before and after the valves being too short, which affects the flow field sensitivity and causes inaccurate measurement, resulting in the system failing to meet energy-saving standards. It also has the functions of emergency shut-off, opening and flow regulation of pipelines.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A multifunctional flow metering device for energy-saving renovation is provided, including a valve, a straight pipe section, a first pipe joint, and a second pipe joint. A flexible joint is installed on the cut end of the first pipe joint, and a valve is installed on the cut end of the second pipe joint. One end of the straight pipe section is inserted into the flexible joint, and the other end is connected to the valve. An adjustable movable flange is fitted onto the end of the straight pipe section near the flexible joint. The movable flange is fixed to the connecting flange of the flexible joint. An opening is provided on the straight pipe section, and a multi-parameter sensor module is installed on this opening. The sensor probe of the multi-parameter sensor module is inserted through the opening to detect the water flow parameters within the straight pipe section.

[0005] This technical solution utilizes a separate straight pipe section to provide a straight medium transport channel, facilitating the installation of multi-parameter sensor modules. Simultaneously, the sensing end of the multi-parameter sensor module can enter the straight pipe section, enabling convenient measurement of parameters such as medium temperature and flow rate. The straight pipe section ensures stable medium transport, resulting in more accurate measured parameters and significantly improving the precision of the obtained parameters. The installation of flexible joints facilitates the concealment of the straight pipe section, allowing for adjustment of its exposed distance. This enables the device to adapt to different installation environments, greatly expanding its applicability.

[0006] As a supplement to this technical solution, the multi-parameter sensor module is equipped with a data processing module and an adaptive calibration module.

[0007] In this technical solution, the multi-parameter sensor module integrates an ultrasonic flow sensor, a temperature sensor, and a pressure sensor, which can synchronously collect fluid flow, temperature, and pressure data in the pipeline in real time. Meanwhile, the data processing module itself is a small computer device. Through built-in energy-saving optimization algorithms, combined with fluid physical properties (density, viscosity), the flow value is dynamically corrected. The adaptive calibration module adopts a dual closed-loop feedback mechanism, trains a flow prediction model based on historical data, compares the measured values ​​with the model values ​​online, and automatically adjusts the sensor sensitivity and signal gain coefficient to ensure that the error across the entire range is within the standard requirements.

[0008] As a supplement to this technical solution, a variable flange is installed on the straight pipe section to connect with the inlet of the valve. The variable flange and the inlet of the valve are connected by several bolts, and a first nut is installed on the bolts, which abuts against the variable flange.

[0009] In this technical solution, a variable flange is set to facilitate the connection between straight pipe sections and valves of different models. At the same time, bolts and a first nut are used to facilitate the connection and fixation of the variable flange and the valve.

[0010] As a supplement to this technical solution, the variable flange is provided with several fixing nuts on the side near the movable flange, and long screws are installed on the fixing nuts. There are several long screws in total, and the long screws are parallel to the straight pipe section. In this technical solution, the fixing nuts are used as the base for installing the long screws.

[0011] As a supplement to this technical solution, one end of the long screw passes through the movable flange and the mating flange of the flexible joint. Positioning nuts that mate with the long screw are installed on both sides of the movable flange and the mating flange. The installation of two positioning nuts facilitates the mating of the movable flange and the mating flange.

[0012] Beneficial Effects: This utility model relates to a multifunctional flow metering device for energy-saving retrofitting. It provides a straight medium transport channel through a separate straight pipe section, facilitating the installation of a multi-parameter sensor module. The sensing end of the multi-parameter sensor module can enter the straight pipe section, allowing for convenient measurement of parameters such as medium temperature and flow velocity. The straight pipe section ensures stable medium transport, resulting in more accurate measurements and significantly improved parameter precision. The installation of a flexible joint facilitates the storage of the straight pipe section, allowing for adjustment of its exposed distance. This enables the device to adapt to different installation environments, greatly increasing its applicability. It features convenient flow meter installation, ensures accurate flow meter measurement, and low retrofitting costs. Attached Figure Description
