Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to an NB water meter with integrated valve. Background Technology

[0002] NB water meters are a type of smart water meter that uses a wireless Internet of Things (IoT) model. Compared to traditional water meters, they offer advantages such as greater ease of use, more accurate metering, and wider coverage. To improve their performance in terms of maintenance efficiency, precise control, water safety, and intelligent management, an NB water meter with an integrated valve is needed.

[0003] The integrated valve NB water meter combines valve control devices with NB technology. It can not only collect and transmit water meter data in real time, but also control the opening and closing status of valves through remote commands. In the past, NB water meters may not have fully considered modular design, resulting in a loose connection between the water meter and the valve or easy damage. Therefore, the previous NB water meters could not achieve the effect of quickly replacing water meters or valves. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated valve NB water meter, which aims to improve the problem that previous NB water meters could not effectively achieve quick replacement of water meters or valves.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An integrated valve NB water meter includes a first connecting cylinder, with a first locking block and a first locking rod fixedly connected to the outer wall of the first connecting cylinder. A fixed cylinder is slidably connected to the inside of the first connecting cylinder. A second connecting cylinder is fixedly connected to the outer wall of the fixed cylinder. A second locking block and a second locking rod are fixedly connected to the outer wall of the second connecting cylinder. The outer wall of the first locking rod is slidably connected to the outer wall of the second locking block, and the outer wall of the second locking rod is slidably connected to the outer wall of the first locking block. A first spring is slidably connected to the inside of the fixed cylinder. A retaining ring is fixedly connected to the inner wall of the first connecting cylinder, and the outer wall of the retaining ring is slidably connected to the outer wall of the fixed cylinder. A metering component is provided on the outer wall of the first connecting cylinder for recording the drainage volume.

[0007] Preferably, the metering component includes a first water pipe, the outer wall of which is fixedly connected to the outer wall of a first connecting cylinder, and the water meter body is fixedly connected inside the first water pipe.

[0008] Preferably, a second water pipe is fixedly connected to the outer wall of the second connecting cylinder, and a first fixing pipe is fixedly connected to the outer wall of the second water pipe.

[0009] Preferably, the first fixed tube has an internal threaded connection to a threaded rod, and a handle is fixedly connected to the top end of the threaded rod.

[0010] Preferably, a connecting block is fixedly connected to the bottom end of the threaded rod, and a cylindrical tube is fixedly connected to the lower surface of the connecting block.

[0011] Preferably, a second fixed tube is fixedly connected inside the first fixed tube, and the outer wall of the cylindrical tube is slidably connected inside the second fixed tube.

[0012] Preferably, a second spring is fixedly connected to the outer wall of the cylindrical tube, and the outer wall of the second spring is slidably connected to the inner wall of the second fixed tube.

[0013] Preferably, a third water pipe is fixedly connected inside the second fixed pipe, and the outer wall of the cylindrical tube is slidably connected to the outer wall of the third water pipe.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, turning the second water pipe drives the second clamp rod to rotate on the first clamp block through the second connecting cylinder. The corresponding first clamp rod will rotate on the second clamp block, and then the fixed cylinder will slide out from the first connecting cylinder, achieving the effect of quickly replacing the water meter or valve, shortening the replacement time, and thus improving maintenance efficiency.

[0016] 2. In this utility model, by turning the handle, the threaded rod is driven to rotate in the first fixed tube, and then the cylindrical tube is pushed to slide in the second fixed tube through the connecting block. Then, while squeezing the second spring, the cylindrical tube loses its seal on the third water pipe, thus achieving the effect of precise control of water flow. In this way, users can manage water usage more effectively and avoid waste. Attached Figure Description

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an integrated valve NB water meter, comprising a first connecting cylinder 3, a first locking block 4 and a first locking rod 5 fixedly connected to the outer wall of the first connecting cylinder 3, a fixed cylinder 6 slidably connected to the inside of the first connecting cylinder 3, a second connecting cylinder 7 fixedly connected to the outer wall of the fixed cylinder 6, a second locking block 8 and a second locking rod 9 fixedly connected to the outer wall of the second connecting cylinder 7, the outer wall of the first locking rod 5 slidably connected to the outer wall of the second locking block 8, the outer wall of the second locking rod 9 slidably connected to the outer wall of the first locking block 4, a first spring 10 slidably connected to the inside of the fixed cylinder 6, a retaining ring 11 fixedly connected to the inner wall of the first connecting cylinder 3, the outer wall of the retaining ring 11 slidably connected to the outer wall of the fixed cylinder 6, and a metering component provided on the outer wall of the first connecting cylinder 3 for recording the drainage volume.

[0025] Specifically, turning the second water pipe 12 rotates the second connecting cylinder 7, which in turn rotates the second locking rod 9 on the first locking block 4. Simultaneously, the first locking rod 5 rotates on the second locking block 8, causing the fixing cylinder 6 to slide out of the first connecting cylinder 3. This allows for the quick removal of the water meter body 2. After inserting the fixing cylinder 6 into the first connecting cylinder 3 by moving the second connecting cylinder 7, turning the first water pipe 1 in the opposite direction rotates the first connecting cylinder 3. The first connecting cylinder 3 then causes the retaining ring 11 to slide on the fixing cylinder 6. By compressing the first spring 10, the water meter body 2 is quickly installed. The first connecting cylinder 3 and the fixing cylinder 6 are sealed together, as are the retaining ring 11 and the fixing cylinder 6, effectively preventing leakage. Under the action of the first spring 10, the connections between the second locking rod 9 and the first locking block 4, and between the first locking rod 5 and the second locking block 8, are made more secure.

[0026] Reference Figure 1 The metering component includes a first water pipe 1, the outer wall of the first water pipe 1 is fixedly connected to the outer wall of the first connecting cylinder 3, and the water meter body 2 is fixedly connected inside the first water pipe 1.

[0027] Specifically, the first water pipe 1 serves to transport water and supports and fixes the water meter body 2. The water meter body 2 can accurately measure the amount of water flowing through the first water pipe 1.

[0028] Reference Figure 1 and Figure 4 A second water pipe 12 is fixedly connected to the outer wall of the second connecting tube 7, and a first fixing pipe 13 is fixedly connected to the outer wall of the second water pipe 12. A threaded rod 14 is threadedly connected to the inside of the first fixing pipe 13, and a handle 15 is fixedly connected to the top of the threaded rod 14. A connecting block 16 is fixedly connected to the bottom of the threaded rod 14, and a cylindrical tube 17 is fixedly connected to the lower surface of the connecting block 16. A second fixing pipe 18 is fixedly connected to the inside of the first fixing pipe 13, and the outer wall of the cylindrical tube 17 is slidably connected to the inside of the second fixing pipe 18. A second spring 19 is fixedly connected to the outer wall of the cylindrical tube 17, and the outer wall of the second spring 19 is slidably connected to the inner wall of the second fixing pipe 18. A third water pipe 20 is fixedly connected to the inside of the second fixing pipe 18, and the outer wall of the cylindrical tube 17 is slidably connected to the outer wall of the third water pipe 20.

[0029] Specifically, by turning the handle 15, the threaded rod 14 is driven to rotate in the first fixed tube 13. The threaded rod 14 pushes the cylindrical tube 17 to slide in the second fixed tube 18 through the connecting block 16. While compressing the second spring 19, it also causes the cylindrical tube 17 to lose its sealing effect on the third water pipe 20, thereby allowing water to flow from the third water pipe 20 through the first fixed tube 13 into the second water pipe 12.

[0030] Working principle: When the water meter is needed, turning the second water pipe 12 rotates the second connecting cylinder 7, which in turn rotates the second locking rod 9 on the first locking block 4. Simultaneously, the corresponding first locking rod 5 rotates on the second locking block 8, allowing the fixing cylinder 6 to slide out of the first connecting cylinder 3, thus quickly removing the water meter body 2. After inserting the fixing cylinder 6 into the first connecting cylinder 3 through the second connecting cylinder 7, turning the first water pipe 1 in the opposite direction rotates the first connecting cylinder 3. The first connecting cylinder 3 causes the retaining ring 11 to slide on the fixing cylinder 6, simultaneously squeezing the first spring 10, thus quickly installing the water meter body 2. Turning the handle 15 rotates the threaded rod 14 on the first fixing pipe 1. In the rotation of the third water pipe 12, the threaded rod 14 pushes the cylindrical tube 17 to slide in the second fixed pipe 18 through the connecting block 16. While compressing the second spring 19, the cylindrical tube 17 loses its seal on the third water pipe 20, allowing water to flow from the third water pipe 20 through the first fixed pipe 13 into the second water pipe 12. This not only achieves the effect of quickly replacing water meters or valves without the need for complex disassembly and reinstallation, greatly simplifying the maintenance process and shortening the replacement time, thus improving maintenance efficiency, but also achieves the effect of precise water flow control. Through precise water flow control, users can manage water usage more effectively and avoid waste. For example, when a large amount of water is not needed, the water flow can be reduced by adjusting the valve, thereby achieving the purpose of saving water.

[0031] 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.
