[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-5 As shown in the figure, this embodiment provides a liquid flow test device with automatic flow rate adjustment.

[0021] A liquid flow testing device with automatic flow regulation includes a storage tank 1, a delivery pump 2 fixedly installed on one side of the storage tank 1, a test tube 3 provided on one side of the delivery pump 2, a return pipe 4 connected to the storage tank 1 fixedly installed at one end of the test tube 3, flow sensors 5 provided at both ends of the test tube 3, a flow regulating valve 6 provided between the delivery pump 2 and the test tube 3, and an assembly structure 7 provided on both the delivery pump 2 and the test tube 3. The assembly structure 7 includes several fixed frames 8 symmetrically fixedly installed at one end of the delivery pump 2 and the test tube 3, a screw 9 movably installed inside the fixed frame 8, a turntable 10 fixedly connected to the screw 9 on the top of the fixed frame 8, a threaded movable block 11 provided on the screw 9, a support rod 12 fixedly installed on one side of the movable block 11, and a clamping plate 13 fixedly installed on the support rod 12.

[0022] With the assembly structure 7, when assembling the flow regulating valve 6, the flow regulating valve 6 is placed between the delivery pump 2 and the test tube 3. Then, the rotating turntable 10 drives the screw 9 to rotate, so that the screw 9 moves the movable block 11 through the threaded transmission. When the movable block 11 moves, it drives the clamping plate 13 to move through the support rod 12, so that the two opposing clamping plates 13 move closer to each other to clamp and fix one end of the flow regulating valve 6. After both ends of the flow regulating valve 6 are clamped, it can be assembled and fixed between the delivery pump 2 and the test tube 3, replacing the traditional welding and assembly method with several bolts and flanges. The disassembly and assembly operation is more convenient, and it is easy to disassemble, maintain and replace the flow regulating valve 6 when it is damaged.

[0023] In this embodiment, as Figures 1-5 As shown, several push rods 14 are uniformly fixedly installed on the surface of the turntable 10, and the push rods 14 are provided with anti-slip texture. A sliding groove is opened on the inner wall of the fixed frame 8. The movable block 11 is slidably connected with the sliding groove. A sealing gasket 15 is fixedly installed on the inner wall of the clamping plate 13. A filter box 16 is fixedly installed on the connecting pipe at one end of the conveying pump 2. A filter screen 17 is provided inside the filter box 16. A sealing cover plate 18 fixedly connected to the filter screen 17 is provided on the top of the filter box 16.

[0024] The push rod 14 facilitates the rotation of the turntable 10 to drive the screw 9. The anti-slip texture increases friction, preventing slippage during operation. The movable block 11 is slidably connected to the groove on the inner wall of the fixed frame 8, limiting its movement on the screw 9. This allows the movable block 11 to smoothly move the support rod 12 and clamping plate 13, preventing the clamping plate 13 from shifting due to the movable block 11 rotating with the screw 9. The sealing gasket 15 enhances the sealing of the connection between the clamping plate 13 and the pump 2 and flow control valve 6, as well as the test tube 3 and flow control valve 6, preventing liquid leakage. The filter box 16, filter screen 17, and sealing cover 18 effectively filter impurities in the liquid, preventing contamination and blockage of the pump 2 and flow control valve 6.

[0025] In this embodiment, as Figures 1-5 As shown, fixing blocks 19 are fixedly installed at both ends of the sealing cover plate 18. Two elastic levers 20 are symmetrically fixedly installed at the bottom of the fixing blocks 19. Locking blocks 21 are fixedly installed at both ends of the filter box 16. One end of the elastic lever 20 is set as an inclined structure. The diameter of the elastic lever 20 is equal to the inner diameter of the locking block 21. The top and bottom of the liquid storage tank 1 are respectively fixedly installed with a first support plate 22 and a second support plate 23. The first support plate 22 is fixedly connected to the bottom of the delivery pump 2 and the test tube 3. Several fixing rings 24 fixedly connected to the return pipe 4 are fixedly installed on the second support plate 23. A water inlet pipe 25 is fixedly installed on the top surface of the liquid storage tank 1. A drain valve 26 is fixedly installed on the bottom surface of the liquid storage tank 1. A PLC controller 27 is fixedly installed on the front of the liquid storage tank 1. A touch panel 28 is fixedly installed on the PLC controller 27. A window frame 29 is fixedly installed on the liquid storage tank 1. An observation window 30 is fixedly installed on the window frame 29.

[0026] By using the fixing block 19, the elastic locking rod 20, and the locking block 21, the sealing cover 18 can be fastened to fix the filter screen 17 in the filter box 16. After the filter screen 17 is installed inside the filter box 16, the sealing cover 18 covers the top of the filter box 16. When the sealing cover 18 is in place, the two elastic locking rods 20 at the bottom of the fixing blocks 19 at both ends are inserted into the locking block 21. The elastic locking rods 20 and the locking block 21 engage to fasten the sealing cover 18, thereby fixing the filter screen 17 in the filter box 16. The elastic lever 20 has a certain degree of elasticity. By pressing one end of the elastic lever 20, it can be separated from the locking block 21, and the sealing cover plate 18 can be pushed upward to remove the filter screen 17 from the filter box 16 for cleaning and to prevent clogging. At the same time, the inclined structure of one end of the elastic lever 20 makes it easier to insert the elastic lever 20 into the locking block 21. Through the setting of the first support plate 22, the second support plate 23 and the fixing ring 24, the first support plate 22 is connected to the bottom of the delivery pump 2 and the test tube 3 to provide support. The second support plate 23 is connected to the return pipe 4 via two fixing rings 24, providing support for the return pipe 4 and making the assembly of the delivery pump 2, test pipe 3, and return pipe 4 on one side of the storage tank 1 more stable. Through the installation of the inlet pipe 25, drain valve 26, PLC controller 27, and touch panel 28, the drain valve 26 at the bottom of the storage tank 1 facilitates the discharge of liquids used for extended periods, while the inlet pipe 25 facilitates the addition and replenishment of liquids into the storage tank 1. Simultaneously, the PLC controller 27, touch panel 28, and delivery... Pump 2, flow sensor 5, and flow regulating valve 6 are connected using existing electrical connection technology. The data collected by the two flow sensors 5 can be transmitted to PLC controller 27, processed, and then transmitted to touch panel 28 for staff to view the detected data. At the same time, touch panel 28 can control the operation of pump 2, flow sensor 5, and flow regulating valve 6, making it convenient for staff to test. The window frame 29 and observation window 30 facilitate the viewing of the liquid inside storage tank 1 during liquid replacement to determine whether the liquid has been completely drained.

[0027] In this embodiment, as Figures 1-5 As shown in the figure, the working process of the liquid flow testing device with automatic flow regulation provided in this embodiment is as follows: When assembling the flow regulating valve 6, it is placed between the delivery pump 2 and the test tube 3. Then, the rotating turntable 10 drives the screw 9 to rotate, causing the screw 9 to move the movable block 11 through threaded transmission. When the movable block 11 moves, it drives the clamping plate 13 to move through the support rod 12, so that the two opposing clamping plates 13 move closer to each other to clamp and fix one end of the flow regulating valve 6. After clamping both ends of the flow regulating valve 6, it can be assembled and fixed between the delivery pump 2 and the test tube 3. When conducting the liquid flow test, the delivery pump 2 is started by the PLC controller 27, so that the delivery pump 2 delivers the liquid in the storage tank 1 to the test tube 3. Two flow sensors 5 are set at both ends of the test tube 3 to monitor the liquid flow rate entering the test tube 3 and the liquid flow rate leaving the test tube 3, respectively, to achieve bidirectional flow monitoring. When adjusting the flow, the flow regulating valve 6 is controlled by the touch panel 28, so that the flow regulating valve 6 can adjust the flow.
