Technical Field

[0001] The utility model relates to the technical field of flow regulating equipment, in particular to a regulating valve for intelligently controlling water flow. Background Art

[0002] A regulating valve is a common device used in pipelines to adjust the transmission state of the fluid in the distribution pipeline. The flow regulating valve is generally used to control the flow.

[0003] In the prior art, regulating valves using ordinary valve cores generally rely on the opening angle of the handle to adjust the water output. However, the opening angle of the handle is difficult to control accurately, and an inappropriate position can easily cause waste of water resources. In addition, it is difficult to accurately control the flow rate using the handle. Therefore, a regulating valve with intelligent water flow control is proposed to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a regulating valve for intelligently controlling water flow, which can adjust the water flow in the current pipeline through the data fed back by the flow meter, and the flow regulation is more detailed and the control is more precise.

[0005] The technical solution to achieve the purpose of the utility model is: a regulating valve for intelligently controlling water flow, comprising a regulating section, a water inlet pipe being provided on one side of the regulating section, a water outlet pipe being provided on the other side of the regulating section, the inner cavity of the regulating section being hollow, a regulating plate being fixedly connected to the inner wall of the regulating section, a regulating component being provided in the regulating section, a PLC control module and a regulating motor being provided on the top of the regulating section, a flow sensor being provided in the water outlet pipe, the flow sensor being electrically connected to the PLC control module, the regulating motor being electrically connected to the PLC control module, the regulating motor being connected to the regulating component, a protective shell being provided on the regulating section, and the PLC control module and the regulating motor being both located in the protective shell.

[0006] In some embodiments, two empty slots are formed through the regulating plate, and the regulating assembly includes a light rod fixedly connected to the inner wall of the regulating section, and the inner wall of the regulating section is rotatably connected to a regulating bidirectional screw rod.

[0007] In some embodiments, the regulating component also includes a driven bevel gear rotatably connected to the inner wall of the regulating section, the inner bottom wall of the regulating section is rotatably connected to a driving bevel gear, the driving bevel gear is meshed with the driven bevel gear, one side of the driven bevel gear is coaxially fixed with one end of the regulating bidirectional screw, and the upper surface of the driving bevel gear is coaxially fixed with the output end of the regulating motor.

[0008] In some embodiments, the regulating assembly further includes connecting frames located on both sides of the regulating plate, the top end of the connecting frame is slidably connected to the optical rod, the top end of the connecting frame is threadedly connected to the regulating bidirectional screw rod, and the sides of the connecting frames close to each other are fixedly connected with wedge blocks, the position of the wedge blocks corresponds to the position of the empty slot of the regulating plate and the shape is adapted thereto.

[0009] In some embodiments, the inner wall of the water outlet pipe is fixedly connected to a fixing plate and a closed ring, one end of the fixing plate is fixedly connected to a sleeve rod, the inner wall of the sleeve rod is slidably connected to an extension rod, the inner wall of the sleeve rod is fixedly connected to a spring, and one end of the spring is fixedly connected to one end of the extension rod.

[0010] In some embodiments, one end of the extension rod away from the spring is fixedly connected to a closing plate, and the closing plate is adapted to the shape of the closing ring.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First: The utility model, through the control plate and control components, when the flow needs to be adjusted, the flow meter will record the water flow data in real time, and then output the signal to the PLC control module. After processing, the PLC control module compares it with the preset data. If, after comparison, the flow needs to be adjusted, the PLC control module transmits the signal to the control motor, and the control motor drives the active bevel gear to rotate, and the active bevel gear drives the driven bevel gear to rotate, thereby causing the control bidirectional screw to rotate. At this time, the connecting frames on both sides will move closer to or away from each other under the drive of the bidirectional screw, thereby causing the two wedge blocks to move away from or closer to each other. When the two wedge blocks move away from each other, the wedge blocks and the empty slots of the control plate are gradually separated, and the gap of the control plate through which water can pass will become larger and larger, thereby increasing the flow rate; when the two wedge blocks move closer to each other, the wedge blocks and the empty slots of the control plate are gradually overlapped, and the gap of the control plate through which water can pass will become smaller and smaller, thereby reducing the flow rate, achieving a more precise control effect;

[0013] Secondly, the utility model provides a closed ring and a closed plate. When the water flows normally, it will impact the closed plate. At this time, the spring is stretched, so that the closed plate is separated from the closed ring, ensuring the circulation of water. When backflow occurs, the closed plate will be pushed by the water flow to re-engage with the closed ring, acting as a one-way valve to prevent the backflow of water from affecting the data monitored by the flow meter, thereby further ensuring the accuracy of regulation.

[0014] The invention solves the problem of inaccurate regulation of the existing regulating valve using a handle as a regulating means. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides an intelligent regulating valve for controlling water flow through improvement. The technical solution of the utility model is:

[0025] like Figure 1As shown, a regulating valve for intelligently controlling water flow includes a regulating section 1, an inlet pipe 2 is provided on one side of the regulating section 1, and an outlet pipe 3 is provided on the other side of the regulating section 1. The inner cavity of the regulating section 1 is hollow, and a regulating plate 4 is fixedly connected to the inner wall of the regulating section 1. A regulating component is provided in the regulating section 1, and a PLC control module 6 and a regulating motor 7 are provided on the top of the regulating section 1. The regulating motor 7 adopts a servo motor. A flow sensor 8 is provided in the outlet pipe 3. The flow sensor 8 belongs to the prior art. The detection end of the flow sensor 8 extends into the water inlet pipe 2, the flow sensor 8 is electrically connected to the PLC control module 6, the regulating motor 7 is electrically connected to the PLC control module 6, and the regulating motor 7 is connected to the regulating component. A protective shell 9 is provided on the regulating section 1, and the PLC control module 6 and the regulating motor 7 are both located in the protective shell 9.

[0026] like Figure 2 and Figure 3 As shown, in one embodiment, two empty slots are opened through the regulating plate 4, and the two empty slots are exactly the same in size. A receiving slot for accommodating part of the regulating component is provided on the inner top wall of the regulating section 1. The regulating component includes a light rod 501 fixedly connected to the inner wall of the regulating section 1, and the inner wall of the regulating section 1 is rotatably connected to a regulating bidirectional screw rod 502.

[0027] In one embodiment, the regulating assembly further includes a driven bevel gear 503 rotatably connected to the inner wall of the regulating section 1, and a driving bevel gear 504 rotatably connected to the inner bottom wall of the regulating section 1. The driving bevel gear 504 meshes with the driven bevel gear 503. One side of the driven bevel gear 503 is coaxially fixed to one end of the regulating bidirectional screw 502. The output end of the regulating motor 7 extends through the regulating section 1, and the upper surface of the driving bevel gear 504 is coaxially fixed to the output end of the regulating motor 7.

[0028] In one embodiment, the regulating assembly further includes a connecting frame 505 located on both sides of the regulating plate 4. The connecting frames 505 on both sides have different lengths to avoid the wedge block 506, thereby reducing the space occupied in the regulating section 1 and reducing the impact on the water flow. The top of the connecting frame 505 is slidably connected to the light rod 501, and the top of the connecting frame 505 is screwed to the regulating bidirectional screw rod 502. The sides of the connecting frames 505 close to each other are fixedly connected with a wedge block 506. The position of the wedge block 506 corresponds to the position of the empty slot of the regulating plate 4 and the shape is adapted thereto. The shape of the wedge block 506 gradually expands from the side close to the regulating plate 4 until the side connected to the connecting frame 505 can completely cover the empty slot on the regulating plate 4.

[0029] like Figure 4 and Figure 5As shown, in one embodiment, the inner wall of the water outlet pipe 3 is fixedly connected to a fixing plate 10 and a closing ring 11, respectively. One end of the fixing plate 10 is fixedly connected to a sleeve rod 12, and an extension rod 13 is slidably connected to the inner wall of the sleeve rod 12. A spring 14 is fixedly connected to the inner wall of the sleeve rod 12, and one end of the spring 14 is fixedly connected to one end of the extension rod 13. When the water flows normally, it will impact the closing plate 15. At this time, the spring 14 is stretched, so that the closing plate 15 is separated from the closing ring 11, ensuring the flow of water. When backflow occurs, the closing plate 15 will be pushed by the water flow to fit into the closing ring 11 again, playing the role of a one-way valve.

[0030] In one embodiment, one end of the extension rod 13 away from the spring 14 is fixedly connected to a closing plate 15 , and the closing plate 15 is adapted to the shape of the closing ring 11 .

[0031] The specific working method is: when the regulating valve of the intelligent water flow control is connected to the water circuit, it is ensured that the water inlet pipe 2 flows into the water normally, and the load connected to the outlet pipe 3, such as a faucet, is used to ensure that the water circuit can be used normally. When making adjustments, the flow meter will first record the water flow data in real time, and then output the signal to the PLC control module 6. After processing, the PLC control module 6 will compare it with the preset data. If the flow needs to be adjusted after the comparison, the PLC control module 6 will transmit the signal to the control motor 7. The control motor 7 drives the active bevel gear 504 to rotate, and the active bevel gear 504 drives the driven bevel gear 503 to rotate, so that the two-way screw rod 502 is rotated. At this time, the connecting frames 50 on both sides are connected. 5 will move closer to or farther from each other under the drive of the bidirectional screw rod, thereby causing the two wedge blocks 506 to move away from or closer to each other. When the two wedge blocks 506 move away from each other, the wedge blocks 506 and the empty slots of the regulating plate 4 are gradually separated, and the gaps in the regulating plate 4 through which water can pass will become larger and larger, thereby increasing the flow rate; when the two wedge blocks 506 move closer to each other, the wedge blocks 506 and the empty slots of the regulating plate 4 are gradually overlapped, and the gaps in the regulating plate 4 through which water can pass will become smaller and smaller, thereby reducing the flow rate and achieving a more precise control effect; and at the same time, the setting of the closing plate 15 and the closing ring 11 acts as a one-way valve when water flows through, preventing the backflow of water from affecting the data monitored by the flow meter, thereby further ensuring the accuracy of the regulation.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
