Description

Technical Field

[0001] This utility model relates to the field of flow regulation technology, and in particular to a pipeline flow regulation device. Background Technology

[0002] This utility model relates to a pipeline flow regulation device. In the prior art, adding a return water pipe to control the dosing flow is a classic, reliable, and low-cost method, particularly suitable for upgrading existing fixed-output dosing systems. This method not only effectively protects the pump but also facilitates flow regulation with a certain degree of accuracy. However, in actual use, due to pipeline vibration or external impacts, the valve plate position of the needle valve is prone to change, leading to alterations in the pipeline flow that are difficult to detect in a timely manner, thus affecting system stability and dosing accuracy. Therefore, this solution proposes a pipeline flow regulation device to address the aforementioned problems. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1 - Figure 4 The pipeline flow regulating device shown includes:

[0021] Main pipe 1, one end of main pipe 1 is equipped with a tee 2, one end of tee 2 is equipped with a water outlet pipe 3, the other end of tee 2 is equipped with a return pipe 4, the middle of the water outlet pipe 3 is equipped with a first needle valve 5, and the middle of the return pipe 4 is equipped with a second needle valve 6.

[0022] The display assembly includes a display panel 9 disposed on the front of the first needle valve 5 and the second needle valve 6. The front of the display panel 9 is provided with a display scale 901. Connectors are provided at the connection points between the display panel 9 and the first needle valve 5 and the second needle valve 6.

[0023] It should be noted that the tee 2 is used to connect the main pipe 1, the outlet pipe 3, and the return pipe 4, allowing water to enter the interior of the outlet pipe 3 and the return pipe 4 through the main pipe 1. The first needle valve 5 and the second needle valve 6 are used to adjust the flow rate inside the outlet pipe 3 and the return pipe 4, respectively. When adjusting the first needle valve 5 and the second needle valve 6, the height of the needle valve adjustment plate can be observed through the display scale 901. If the height of the valve plate changes due to vibration or collision, it can be directly observed through the display plate 9 and the display scale 901, avoiding the situation where the pipeline flow rate is automatically adjusted but cannot be detected.

[0024] Specifically, a water pump 7 is installed in the middle of the main pipe 1. The water pump 7 is used to transport medicine. A flow meter 8 is installed on one side of the first needle valve 5. The flow meter 8 is located on one side of the outlet pipe 3.

[0025] It should be noted that the flow meter 8 is an existing ultrasonic flow meter, which calculates the flow velocity by detecting the time difference or frequency difference of ultrasonic waves propagating in the forward and reverse directions. In use, the flow meter 8 is connected to the outlet pipe 3 through flanges and bolts on both sides, thus fixing the flow meter 8 to the outlet pipe 3. The water flow rate inside the outlet pipe 3 is observed through the flow meter 8. The water pump 7 is an existing pipeline pump, which is connected to the main pipe 1 through flanges and bolts. The core working principle is to use the centrifugal force generated by the high-speed rotation of the impeller to transport liquid. Specifically, after the water pump 7 is started, the motor drives the impeller on the pump shaft to rotate at high speed. The liquid between the impeller blades is thrown from the center of the impeller to the edge under the action of centrifugal force. In this process, the kinetic energy and pressure energy of the liquid increase significantly. Subsequently, this high-speed liquid enters the volute-shaped pump chamber around it. The flow channel design of the volute gradually widens, further converting most of the kinetic energy into pressure energy, and finally discharged from the outlet, thus realizing water transportation.

[0026] Furthermore, when using the water pump 7, start it and set it to the desired fixed output value. Slowly open the second needle valve 6 and observe the main flow meter 8. By adjusting the opening of the second needle valve 6, the main flow rate can be precisely adjusted to the target value. Once adjusted, no further action is needed unless the target flow rate changes.

[0027] Specifically, the top of the first needle valve 5 and the second needle valve 6 are both provided with threaded rods 501, and the top of the threaded rods 501 is provided with handles 502.

[0028] It should be noted that both the first needle valve 5 and the second needle valve 6 are equipped with threaded rods 501 at their tops. The threaded rods 501 are connected to the valve plate inside the needle valve through a hinge structure, allowing the threaded rods 501 to rotate on the top of the valve plate. In use, the handle 502 drives the threaded rods 501 to rotate, causing the rotating threaded rods 501 to move on the outer shell of the needle valve. The moving threaded rods 501 then drive the valve plate inside the needle valve to move, thereby regulating the flow rate inside the needle valve.

[0029] Specifically, the connector includes a connecting plate 10 fixedly connected to the top of the display panel 9. A rotating ring 13 is fixedly connected to one side of the connecting plate 10. The rotating ring 13 is sleeved on the middle of the threaded rod 501. A second fixing ring 11 and a first fixing ring 12 are symmetrically arranged at the top and bottom of the rotating ring 13. Both the second fixing ring 11 and the first fixing ring 12 are sleeved on the top of the threaded rod 501.

[0030] It should be noted that the first fixed ring 12 and the second fixed ring 11 are both fixedly sleeved on the top of the threaded rod 501, and the rotating ring 13 is sleeved on the top of the threaded rod 501, and the rotating ring 13 is located between the two fixed rings, so that the rotating ring 13 does not rotate when the threaded rod 501 rotates.

[0031] Furthermore, when it is necessary to adjust the height of the valve plate, turn the handle 502, which will drive the threaded rod 501 to rotate, and the moving threaded rod 501 will drive the second fixed ring 11 and the display plate 9 to move.

[0032] Specifically, an observation block 14 is fixedly connected to the top of the first needle valve 5, and a display panel 9 is inserted and connected to the top of the observation block 14.

[0033] It should be noted that the observation block 14 is fixedly connected to the needle valve by welding. A through hole is provided on the observation block 14, and the display panel 9 is inserted and connected to the observation block 14 through the through hole. The opening height of the needle valve plate is observed by the position of the observation block 14 on the display panel 9.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
