[0027] Example

[0028] Reference Figure 1-6 , is an embodiment of the utility model, which provides a precise flow regulating device of an intelligent flow meter, comprising:

[0029] A measuring pipe 1, a sensor 2, a display instrument panel 3 and a filtering mechanism 4. The sensor 2 is fixedly installed inside the measuring pipe 1, the display instrument panel 3 is fixedly installed on the top of the measuring pipe 1, and the filtering mechanism 4 is fixedly installed on the left side of the measuring pipe 1. The filtering mechanism 4 includes a filtering pipe 401, a mounting groove 402, a fixing frame 403, a filter screen 404 and a mounting block 405. The filtering pipe 401 is fixedly installed on the left side of the measuring pipe 1, the mounting groove 402 is opened in the inner cavity of the filtering pipe 401, the fixing frame 403 is fixedly installed in the inner cavity of the filtering pipe 401, the filter screen 404 is fixedly installed in the inner cavity of the fixing frame 403, and a plurality of mounting blocks 405 are respectively fixedly connected to the four sides of the fixing frame 403, and the mounting blocks 405 are adapted to the mounting groove 402.

[0030] Specifically, a quasi-spherical table-shaped metering chamber 5 is provided inside the measuring pipe 1 , and a partition plate 6 is fixedly installed in the inner cavity of the quasi-spherical table-shaped metering chamber 5 .

[0031] Furthermore, the provision of the quasi-spherical table-shaped metering chamber 5 facilitates the passage of fluid therethrough and pushes the disc 201 .

[0032] Specifically, the sensor 2 includes a disc 201 , a ball shaft 202 , a driven wheel 203 , a driving wheel 204 , a rotating shaft 205 and a motor 206 . The disc 201 is fixedly mounted inside the quasi-spherical table-shaped metering chamber 5 , and the ball shaft 202 is fixedly mounted in the inner cavity of the disc 201 .

[0033] Furthermore, by providing the sensor 2, the disc 201 can generate rotational power under the action of fluid power, and the driving force of the fluid on the disc 201 can be converted into an electrical signal.

[0034] Specifically, the driven wheel 203 is fixedly mounted on the top of the ball shaft 202 , the driving wheel 204 is fixedly mounted on the top of the driven wheel 203 , the rotating shaft 205 is fixedly mounted on the top of the driving wheel 204 , and the motor 206 is fixedly mounted on the top of the rotating shaft 205 .

[0035] Further, the motor 206 is started, the motor 206 drives the rotating shaft 205 to rotate, the rotating shaft 205 drives the driving wheel 204 to rotate, the driving wheel 204 drives the driven wheel 203 to rotate, the driven wheel 203 drives the ball shaft 202 to rotate, and the ball shaft 202 drives the disc 201 to rotate.

[0036] Specifically, a first connecting flange 7 is fixedly connected to the left side of the measuring pipe 1 , an inlet 8 is provided on the left side of the first connecting flange 7 , and a plurality of first mounting holes 9 are respectively provided around the inlet 8 .

[0037] Furthermore, the provision of the inlet 8 facilitates the fluid to flow smoothly into the quasi-spherical table-shaped metering chamber 5 .

[0038] Specifically, a second connecting flange 10 is fixedly connected to the right side of the measuring pipe 1 , a flow outlet 11 is provided on the right side of the second connecting flange 10 , and a plurality of second mounting holes 12 are respectively provided around the flow outlet 11 .

[0039] Furthermore, the second connecting flange 10 is used to tightly connect the flow meter with other pipeline systems to ensure smooth transfer of the fluid.

[0041] Furthermore, by using the positioning pin 13 and the fastening nut 14 in coordination, the filter mechanism 4 can be easily installed and disassembled, thereby facilitating the maintenance of the filter mechanism 4 .

[0042] When in use, the flow regulating device is installed on the fluid pipeline to be measured to ensure a stable connection, and the motor 206 is started. The fluid first passes through the filtering mechanism 4 to filter impurities, and the filtered pure fluid then enters the measuring pipeline 1 from the inlet 8. The fluid pushes the disc 201 to swing and rotate, and at the same time gradually discharges the fluid filling the outflow side space to the outlet 11. While the disc 201 rotates, the driven wheel 203 at the end of the ball shaft 202 rotates around the driving wheel 204, and transmits the number of rotations of the disc 201 to the display instrument panel 3, and the fluid data passing through the flow disc meter is displayed on the display instrument panel 3.

[0043] In summary, by setting up a filter mechanism 4 in the flow regulating device, impurities in the fluid can be effectively filtered out, thereby protecting the device and measuring components from damage and ensuring that the flow meter obtains more accurate data during the measurement process. Without the interference of impurities, the measurement results of the flow meter will be more accurate and reliable. The filter mechanism 4 uses the mounting groove 402 and the mounting block 405 in coordination, making it easier to replace and clean the filter net 404. The filter mechanism 4 can be cleaned or replaced regularly to maintain its good working condition and extend the service life of the equipment and the entire system.
