Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to an intelligent flow control device. Background Art

[0002] Fluids such as water are transmitted through pipelines. The flow control device adjusts factors such as the water flow rate so that the final drainage volume is controlled within a certain range to achieve the effect of flow control. With the development of technology, more intelligent electronic control devices are now used to replace the traditional manual adjustment method;

[0003] Although the existing intelligent flow control devices can achieve the control of the final drainage volume, they are relatively expensive, and the subsequent inspection and maintenance operations of electronic devices will also increase the final cost. Therefore, it is particularly important to develop a flow control device that can intelligently adjust the fluid flow rate and has a simple structure and low cost. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that the existing intelligent flow control devices can achieve the control of the final drainage volume, but they are relatively expensive, and the subsequent inspection and maintenance operations of electronic devices will also increase the final cost, and to propose an intelligent flow control device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An intelligent flow control device includes a pipe body and a through cavity inside the pipe body. A frustum-shaped through hole is arranged inside the through cavity;

[0007] A frustum-shaped core body is used to adjust the water flow volume of the fluid. The frustum-shaped core body is located inside the through cavity, and the outer wall of the frustum-shaped core body is matched with the inner wall of the frustum-shaped through hole;

[0008] A regulation component is used to regulate the position of the frustum-shaped core body. The regulation component is arranged inside the pipe body.

[0009] In a possible design, flange rings are fixedly arranged at both ends of the outer wall of the pipe body.

[0010] In a possible design, the regulation component includes an annular sealing plate. An annular pressure cavity is opened inside the pipe body. The annular sealing plate is located inside the annular pressure cavity. A plurality of sliding grooves are opened on the inner wall of the through cavity. A through groove is communicated between each of the plurality of sliding grooves and the annular pressure cavity. A plurality of connecting rods are fixedly arranged on the outer wall of the frustum-shaped core body. The other end of the connecting rod is fixedly provided with a sliding rod. The other end of the sliding rod is fixedly arranged with the annular sealing plate through the through groove.

[0011] In a possible design, a pressure relief hole communicating with the annular pressure chamber is formed in the outer wall of the pipe body, a pressure adding hole communicating with the annular pressure chamber is formed in the outer wall of the pipe body, and two air valves are fixedly arranged on the outer wall of the pipe body, and the two air valves are respectively matched with the pressure relief hole and the pressure adding hole.

[0012] In a possible design, a rubber gasket is fixedly arranged on one side of the annular sealing plate.

[0013] In a possible design, a gas pressure gauge is arranged on the outer wall of the pipe body, and the gas pressure gauge is matched with the annular pressure chamber.

[0014] In this application, during specific use, the pipe body is installed between two pipelines through two flange rings, and water flows through the frustum-shaped core body and circulates through the frustum-shaped through hole. When the flow rate increases and the drainage volume increases, the water will increase the pressure on the frustum-shaped core body to push the frustum-shaped core body. At this time, the frustum-shaped core body will drive the annular sealing plate to move through the connecting rod and the sliding rod, so that the gas inside the annular pressure chamber is squeezed. At this time, the gap between the frustum-shaped core body and the frustum-shaped through hole will decrease, so as to reduce the water passing volume, thereby avoiding the problem of increased drainage volume caused by increased flow rate; on the contrary, when the flow rate slows down and the drainage volume decreases, the pressure of the water on the frustum-shaped core body decreases, and the annular sealing plate will be rebounded by the compressed gas inside the annular pressure chamber, so that the frustum-shaped core body moves in the reverse direction, thereby increasing the gap between the frustum-shaped core body and the frustum-shaped through hole. As for the displacement distance of the frustum-shaped core body under pressure, it can be adjusted by pressurizing or decompressing the inside of the annular pressure chamber through the two air valves.

[0015] In the present utility model, for the intelligent flow control device, through the frustum-shaped core body, it can achieve adjusting the drainage volume by controlling the position of the frustum-shaped core body, so as to realize that when the flow rate increases, the gap between the frustum-shaped core body and the frustum-shaped through hole is reduced, thereby reducing the water passing volume, and when the flow rate decreases, the gap between the frustum-shaped core body and the frustum-shaped through hole is increased, thereby increasing the water passing volume, so that the final drainage volume is always controlled within a certain range;

[0016] In the present utility model, for the intelligent flow control device, through the regulation component, it can achieve automatically increasing the pressure on the frustum-shaped core body when the flow rate increases, so that the gas inside the annular pressure chamber is compressed, driving the frustum-shaped core body to displace. When the flow rate increases, the pressure on the frustum-shaped core body decreases, so as to realize that the compressed gas pushes the frustum-shaped core body to move in the reverse direction, achieving the effect of increasing the gap between the frustum-shaped core body and the frustum-shaped through hole;

[0017] In the present utility model, during use, the pipe body is installed between two pipelines through a flange ring, and the frustum-shaped core is located on the side facing the water inlet. Then, when the fluid passes through, the frustum-shaped core will be squeezed, and when the flow rate increases or decreases, the displacement of different positions of the frustum-shaped core can be achieved through the regulation component.

[0018] When the increase in flow rate causes an increase in drainage volume, the water passing volume will be reduced. Conversely, when the flow rate increases, the water passing volume will be increased, so that the final drainage volume is always controlled within a certain range. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Refer to Figure 1-2 , an intelligent flow control device, which is applied in the pipeline field and includes: a pipe body 1, a frustum-shaped core 6 and a regulation component. A through cavity 16 is provided inside the pipe body 1, and a frustum-shaped through hole 10 is provided in the through cavity 16. The frustum-shaped core 6 is placed in the through cavity 16, and its outer wall cooperates with the inner wall of the frustum-shaped through hole 10. When the increase in flow rate causes an increase in drainage volume, the frustum-shaped core 6 is controlled to move to reduce the gap between the frustum-shaped core 6 and the frustum-shaped through hole 10, thereby reducing the water passing volume. Conversely, when the flow rate increases, the water passing volume will be increased, so that the final drainage volume is always controlled within a certain range, and the movement of the frustum-shaped core 6 is achieved through the regulation component.

[0026] Embodiment 2

[0027] Refer toFigure 2-3 , based on the improvement of Embodiment 1: The control component includes an annular sealing plate 11, an annular pressure chamber 13, a chute 9, a through groove 15, a connecting rod 7 and a sliding rod 8. The annular pressure chamber 13 is opened inside the pipe body 1, and the annular sealing plate 11 is placed therein, and the sealing effect is ensured through a rubber gasket 12. A plurality of chutes 9 on the inner wall of the through cavity 16 are communicated with the annular pressure chamber 13 through the through groove 15. The frustum-shaped core 6 is connected to the sliding rod 8 through a plurality of connecting rods 7, and the other end of the sliding rod 8 passes through the through groove 15 and is fixed to the annular sealing plate 11, thus forming an overall control mechanism;

[0028] Specifically, when the flow rate increases and the drainage volume increases, the water will increase the pressure on the frustum-shaped core 6 to push the frustum-shaped core 6. At this time, the frustum-shaped core 6 will drive the annular sealing plate 11 to move through the connecting rod 7 and the sliding rod 8, so that the gas inside the annular pressure chamber 13 is squeezed. At this time, the gap between the frustum-shaped core 6 and the frustum-shaped through hole 10 will decrease, so as to reduce the water flow rate, thus avoiding the problem of increased drainage volume caused by increased flow rate; on the contrary, when the flow rate slows down and the drainage volume decreases, the pressure of the water on the frustum-shaped core 6 decreases, and the annular sealing plate 11 will be rebounded by the compressed gas inside the annular pressure chamber 13, so that the frustum-shaped core 6 moves in the reverse direction, thereby increasing the gap between the frustum-shaped core 6 and the frustum-shaped through hole 10.

[0029] A pressurizing hole 5 and a pressure relief hole 14 are provided on the outer wall of the pipe body 1, and both holes are provided with air valves 3. The displacement distance of the frustum-shaped core 6 under pressure can be adjusted by pressurizing or decompressing the inside of the annular pressure chamber 13 through the two air valves 3. The gas pressure gauge 4 on the outer wall of the pipe body 1 can monitor the gas pressure inside the annular pressure chamber 13 in real time to ensure the accuracy and safety of the adjustment.

[0030] The pipe body 1 is installed between two pipes through two flange rings 2, and the frustum-shaped core 6 is located on the side facing the water inlet.
