DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0032] Figure 1 This is a schematic diagram of the structure of a valve-controlled pulsating flow generating device provided by the utility model. Figure 1 As shown, the valve-controlled pulsating flow generating device comprises: a first water tank 10, a pulsating flow generating structure 20, a first valve 30, an overflow structure 40, a second water tank 50 and a second valve 60. The arrows exemplarily indicate the flow direction of the liquid.

[0033] Specifically, Figure 1 As shown, the water outlet of the first water tank 10 is connected to the water inlet of the second water tank 50 through a first pipe section, and the water outlet of the second water tank 50 is connected to the water inlet of the first water tank 10 through a second pipe section; wherein, the first water tank 10 and the second water tank 50 are both used to store liquid and can be used as instruments for storing liquid. Optionally, the vertical distance between the first water tank 10 and the horizontal plane can be smaller than the vertical distance between the second water tank 50 and the horizontal plane.

[0034] Specifically, the pulsating flow generating structure 20 is connected to the first pipe section and is located on a side close to the first water tank 10, so as to generate a pulsating flow in the liquid flowing out of the first water tank 10. Optionally, the vertical distance between the pulsating flow generating structure 20 and the horizontal plane can be the same as or similar to the vertical distance between the first water tank 10 and the horizontal plane.

[0035] Specifically, the overflow structure 40 is disposed between the first pipe section and the second water tank 50, and is used to keep the liquid flowing into the second water tank 50 in a stable state.

[0036] Exemplarily, the liquid flowing out of the first water tank 10 generates a pulsating flow through the pulsating flow generating structure 20, and then flows to the water inlet of the second water tank 50 through the first pipe section and enters the second water tank 50. The liquid flowing into the second water tank 50 then flows out from the water outlet of the second water tank 50, and flows back to the first water tank 10 through the second pipe section to achieve the recycling of the liquid.

[0037] In this embodiment, the pulsating flow generating structure is directly connected to the first pipe segment to form a circulating water circuit consisting of the first water tank, the pulsating flow generating device, the second water tank, the first pipe segment and the second pipe segment. The pulsating flow generating device is directly combined with the pipeline and other instruments to form a complete pulsating flow generating device to solve the problem in the prior art that the pulsating flow generating device can only generate pulsating flow. At the same time, by setting two water tanks between the first pipe segment and the second pipe segment, it is achieved that when the pulsating flow generating structure is used to generate pulsating flow, the liquid in the pipe segment can also be recycled.

[0038] Specifically, the first valve 30 is disposed on the first pipe section and is located between the overflow structure 40 and the pulsating flow generating structure 20; the second valve 60 is disposed on the second pipe section; the first valve 30 and the second valve 60 are both used to control the flow of liquid in the corresponding pipe section. Optionally, the vertical distance between the first valve and the horizontal plane can be greater than the vertical distance between the pulsating flow generating structure 20 and the horizontal plane, and can be less than the vertical distance between the overflow structure 40 and the horizontal plane.

[0039] For example, Figure 1 As shown, the first valve 30 is disposed on the first pipe section, specifically between the pulsating flow generating structure 20 and the overflow structure 40, and close to the overflow structure 40. When the liquid flows out of the first water tank 10, a pulsating flow is generated through the pulsating flow generating structure 20, and flows to the first valve 30. If the user needs to control the flow of the liquid in the pipe section at this time, for example, the flow rate of the liquid needs to be limited, the first valve 30 can be used to control the flow rate of the liquid with the pulsating flow flowing out of the pulsating flow generating structure 20 into the overflow structure 40.

[0040] For example, Figure 1 As shown, the second valve 60 is disposed on the second pipe section, specifically near the water outlet of the second water tank 50, and its vertical distance from the horizontal plane is less than the vertical distance from the second water tank 50 to the horizontal plane, and greater than the vertical distance from the first water tank 10 to the horizontal plane. When the liquid flows back from the second water tank 50 to the first water tank 10, if the user needs to control the flow of the liquid in the pipe section, the second valve 60 can be used to control the flow of the liquid entering the first water tank 10.

[0041] In this embodiment, the first valve is used to control the flow rate of the liquid entering the overflow structure, and the second valve is used to control the flow rate of the liquid flowing out of the second water tank, thereby realizing the function of regulating the flow rate of the liquid by valve control. At the same time, when the liquid in the pipe section overflows at the overflow structure, the first valve can be used to control the flow rate of the liquid flowing into the overflow structure to reduce the working pressure of the overflow structure, thereby realizing a quick solution to the current liquid overflow phenomenon.

[0042] Optional, Figure 2This is a structural example diagram of the pulsating flow generating structure provided by the utility model. Figure 2 As shown, the pulsating flow generating structure 20 comprises: a sleeve 202, a knob 201 and a rotating structure 203. The rotating structure 203 is sleeved inside the sleeve. For example, it can be sleeved on the inner wall of the sleeve.

[0043] in, Figure 3 This is a structural example diagram of the rotating structure provided by the utility model. Figure 3 As shown, the rotating structure 203 includes a rotating shaft 203a, moving blades 203c and stationary blades 203b. A knob 201 is connected to the outside of the connection between the rotating shaft 203a and the sleeve 202. That is, the knob 201 can control the rotation of the rotating shaft 203a. The moving blades 203c are evenly fixed on the rotating shaft 203a; the rotating shaft 203a includes a plurality of telescopic holes 203d, one telescopic hole 203d corresponds to one stationary blade 203b, and each stationary blade 203b can be rotated out from the corresponding telescopic hole 203d under the control of the knob 201 to be evenly distributed on the rotating shaft. In actual operation, the moving blades 203c are driven by the rotating shaft to rotate around the stationary blades, and the blade group operation completes the periodic opening and closing of the pipeline to achieve the occurrence of pulsating flow.

[0044] Specifically, the sleeve 202 is used to protect the pulsating flow generating structure 20, mainly used to protect the rotating structure 203. For example, to prevent the rotating structure 203 from being dusted.

[0045] For example, in Figure 3 In the figure, the telescopic hole 203d is represented by a solid ellipse and a dotted ellipse. The solid ellipse is the telescopic hole on the front of the shaft, and the dotted ellipse is the telescopic hole on the back of the shaft. The figure only shows one telescopic hole on the front of the shaft and two telescopic holes on the back of the shaft. Figure 3 In the embodiment, the stationary blade 203b is in the state of being rotated out from the telescopic hole. When not being rotated out, the stationary blade 203b is located inside the rotating shaft.

[0046] Exemplarily, telescopic holes and blades may be provided at different radial positions of the rotating shaft 203 a to ensure the stability of the pulsating flow of the liquid passing through the pulsating flow generating structure 20 .

[0047] It is worth noting that in order to make the specific positions of the rotating shaft 203a, the moving blades 203c and the stationary blades 203b in the rotating structure more clearly expressed, Figure 3 In the figure, the structural relationship between the moving blade 203c and the stationary blade 203b is shown at a certain angle. In practice, the moving blade 203c and the stationary blade 203b should be perpendicular to the rotating shaft 203a, and the moving blade 203c and the stationary blade 203b should be parallel.

[0048] Optionally, the pulsating flow generating structure 20 further includes a slideway 204. Figure 2As shown, the inner wall of the sleeve 202 is provided with a slideway 204. Exemplarily, the slideway 204 is provided on both sides of the inner wall of the sleeve 202 to form a parallel slideway structure. Exemplarily, when the stationary blade 203b in the telescopic hole 203d is rotated out, the stationary blade 203b can be directly embedded in the slideway to play a role in fixing the stationary blade, so that when the moving blade 203c on the driving shaft 203a rotates later, the stationary blade 203b can remain stationary. At the same time, the overall structure of the pulsating flow generating structure 20 can also be made more stable.

[0049] In this embodiment, a plurality of telescopic holes are provided on the rotating shaft to recover the stationary blades. When the stationary blades are needed, the stationary blades are rotated out of the telescopic holes by rotating the rotating shaft and fixed on the slideway, making the use and recovery of the stationary blades more convenient. Moreover, the installation of the slideway can not only fix the stationary blades, but also make the overall structure of the pulsating flow generating structure more stable.

[0050] Optionally, the overflow structure 40 includes a flow field stabilizing structure 402 and an overflow pipe 401 . Figure 4 This is a structural example diagram of the overflow structure provided by the utility model. Figure 4 As shown, the overflow pipe 401 is connected to the first pipe section, and is used to guide the liquid flowing out of the first pipe section to the flow field stabilizing structure 402. The arrow indicated by the dotted line is the flow direction of the liquid. The flow field stabilizing structure 402 is fixed in the second water tank 50, and the flow field stabilizing structure 402 is arranged corresponding to the overflow pipe 401, and is used to mitigate the impact force of the liquid flowing into the second water tank 50.

[0051] Exemplarily, the flow field stabilizing structure 402 includes a flexible short plate 402a and a flexible long plate 402b; the distance between the flexible short plate 402a and the bottom of the second water tank 50 is greater than the distance between the flexible long plate 402b and the bottom of the second water tank 50, and the length of the flexible long plate 402b is greater than the length of the flexible short plate 402a. Preferably, the flexible short plate 402a is located at two-thirds of the bottom of the second water tank 50, and the length of the flexible short plate 402a can be one-third of the length of the second water tank. The flexible long plate 402b is located at one-third of the bottom of the second water tank 50, and the length of the flexible long plate 402b can be two-thirds of the length of the second water tank.

[0052] In this embodiment, in the overflow structure, the overflow pipe is used to reduce the adverse effects caused by the overflow of the liquid back to the front position when the liquid in the water tank reaches saturation. The overflow pipe is used to limit the flow of the liquid overflowing back to the front position, thereby ensuring the overall stability of the liquid in the device. At the same time, the flow field stabilization structure set in the second water tank can prevent the liquid from falling directly into the second water tank from the overflow pipe, thereby reducing the impact force on the water in the second water tank, and ensuring the accuracy of the device when performing calibration. In actual use, the overflow structure can be continuously kept in an open state, thereby ensuring the stability, reproducibility and accuracy of the measurement.

[0053] Figure 5 This is a schematic diagram of the structure of another valve-controlled pulsating flow generating device provided by the utility model. Figure 5 As shown, the valve-controlled pulsating flow generating device provided by the utility model further includes: a first flow measurement structure 70. The first flow measurement structure 70 is arranged between the pulsating flow generating structure 20 and the first valve 30, and is used to measure the pulsating flow of the liquid with pulsating flow generated by the pulsating flow generating structure 20.

[0054] Exemplarily, sensors 80 are provided at the water inlet and the water outlet of the first flow measurement structure 70. Preferably, the sensors may be pressure sensors and temperature sensors for detecting the pressure and temperature of the liquid flowing into the first flow measurement structure 70, and detecting the pressure and temperature of the liquid flowing out of the first flow measurement structure 70. Preferably, the first flow measurement structure 70 is connected to the first pipe section by an elastic hose for matching different interfaces.

[0055] Optional, such as Figure 5 As shown, the valve-controlled pulsating flow generating device provided by the utility model further includes: a second flow measurement structure 90; the second flow measurement structure 90 is arranged between the second valve 60 and the first water tank 10, and is used to measure the liquid flowing in the second pipe section. The vertical distance between the second flow measurement structure 90 and the horizontal plane is slightly higher than the vertical distance between the second valve 60 and the horizontal plane. The measurement content is generally the measurement of steady flow.

[0056] For example, in one implementation, if it is necessary to detect a pulsating flow, the second flow measurement structure 90 can be turned off, and only the first flow measurement structure 70 and other structures are kept open and working. In another implementation, if it is necessary to detect a steady flow, the pulsating flow generating structure 20 and the first flow measurement structure 70 can be turned off, and only the second flow measurement structure 90 and other structures are kept open and working.

[0057] In this embodiment, a first flow measurement structure for detecting pulsating flow and a second flow measurement structure for detecting steady flow are added to the pulsating flow generating device, so that the valve-controlled pulsating flow generating device provided by the utility model can not only realize the generation of pulsating flow, but also take into account the measurement of pulsating flow, and can also choose to measure steady flow when the pulsating flow generating structure is not enabled. At the same time, in combination with the first valve and the second valve, the flow rate of the liquid can be controlled, and the problem that the measurement data of the off-site flow measurement structure is affected by the overflow of liquid from the water tank and the front position of the water tank is affected by the overflow of liquid can be solved. In addition, in combination with the first valve, the second valve, the first flow measurement structure and the second flow measurement structure, not only the accumulated flow over a period of time can be accurately measured, but also the change of instantaneous flow can be truly reflected.

[0058] Optionally, the valve-controlled pulsating flow generating device provided by the utility model further includes: a weighing structure 100. The weighing structure 100 is used to measure the mass of the liquid in the first water tank 10. Exemplarily, the weighing structure can be a mechanical scale, an electronic scale, or an electromechanical combined scale. Preferably, the weighing structure 100 can be arranged directly below the first water tank 10.

[0059] The utility model provides a valve-controlled pulsating flow generating device, comprising: a first water tank, a pulsating flow generating structure, a first valve, an overflow structure, a second water tank and a second valve; wherein the water outlet of the first water tank is connected to the water inlet of the second water tank through a first pipe section, and the water outlet of the second water tank is connected to the water inlet of the first water tank through a second pipe section; the first water tank and the second water tank are both used to store liquid; the pulsating flow generating structure is connected to the first pipe section and is located on a side close to the first water tank, and is used to cause the liquid flowing out of the first water tank to generate a pulsating flow; the first valve is arranged on the first pipe section and is located between the overflow structure and the pulsating flow generating structure; the second valve is arranged on the second pipe section; the first valve and the second valve are both used to control the flow of liquid in the corresponding pipe section. In the above technology, on the one hand, the pulsating flow generating structure is directly connected to the first pipe section to form a circulating water circuit consisting of the first water tank, the pulsating flow generating device, the second water tank, the first pipe section and the second pipe section. The pulsating flow generating device is directly combined with the pipeline and other instruments to form a complete pulsating flow generating device, so as to solve the problem that the pulsating flow generating device can only realize the generation of pulsating flow in the prior art; and the existing pulsating flow generating device needs to cooperate with other equipment, such as a water tank for water supply and a valve for regulating liquid flow, to realize the detection of pulsating flow when performing pulsating flow verification. At the same time, by setting two water tanks between the first pipe section and the second pipe section, it is realized that when the pulsating flow generating structure is used to generate pulsating flow, the liquid in the pipe section can also be recycled. On the other hand, the flow rate of the liquid entering the overflow structure is controlled by the first valve, and the flow rate of the liquid flowing out of the second water tank is controlled by the second valve, so that the valve control can adjust the flow rate of the liquid. At the same time, when the liquid in the pipe section overflows at the overflow structure, the first valve can be used to control the flow rate of the liquid flowing into the overflow structure to reduce the working pressure of the overflow structure, so as to quickly solve the current liquid overflow phenomenon. At the same time, the first valve and the second valve can be used to adjust the flow rate of the liquid, which provides a more stable and accurate calibration device for calibrating the pulsating flow using the valve-controlled pulsating flow generating device provided by the utility model.

The electronic device A may also represent various forms of mobile devices, such as personal digital processing, cellular phones, smart phones, wearable devices (such as helmets, glasses, watches, etc.) and other similar computing devices. The electronic device A and the valve-controlled pulsating flow generating device communicate via a serial port.

[0062] In this embodiment, the electronic device A may be a computer, and may be used to receive the measurement results obtained by each structure in the valve-controlled pulsating flow generating device. For example, the electronic device A may receive the mass of water in the first water tank 10 measured by the weighing structure 100, may receive the detection results from the first flow measurement structure 70 and the sensor 80, and may receive the detection results from the second flow measurement structure 90.
