[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Taking water storage towers as an example, existing water storage towers are usually composed of a group of large-diameter water storage columns, which are equipped with water pumps to discharge water. The large-diameter water storage columns simultaneously supply multi-diameter pipe networks. However, this setting method has unstable water discharge, and the flow distribution in the multi-diameter pipe network fluctuates, which affects the measurement results.

[0032] Therefore, refer to Figure 1 —10. The utility model provides a water tower for ultrasonic water meter testing, including a water tower body 100. The water tower body 100 is hollow inside, and is provided with a group of water outlet pipes and a group of water inlet pipes. A water storage part 101 is provided on the top of the water tower body 100, and a base 102 is provided on the bottom. One end of the water inlet pipe is connected to an external water pipe, and the other end rises along the water tower body 100 and is connected to the top of the water storage part 101. One end of the water outlet pipe is connected to the bottom of the water storage part 101, and the other end is connected to a flow test bench of each caliber pipe network.

[0033] Wherein, each water inlet pipeline and each water outlet pipeline is provided with a set of valve-controlled metering components, and the valve-controlled metering components include flow meters and valves.

[0034] Specifically, the flow meter adopts an ultrasonic water meter, the valve above the water pipe adopts a flange type butterfly valve, and the valve below the water pipe adopts a wafer type butterfly valve.

[0035] Specifically, each water inlet pipeline and each water outlet pipeline are provided with 2 sets of valve-controlled metering components;

[0036] Among them, one set is arranged at the top end of the pipeline near the water storage part 101, and another set is arranged at the bottom end of the pipeline near the base 102.

[0037] Specifically, the water inlet pipeline is provided with 3 water inlet pipelines with different calibers, and their calibers are DN125, DN200 and DN300 respectively; the water outlet pipeline is provided with 6 water outlet pipelines with different calibers, and their calibers are DN100, DN125, DN200, DN300, DN500 and DN600 respectively.

[0038] Specifically, one pipe is provided for each of the three water inlet pipes of different diameters; among the water outlet pipes, six pipes are used for the DN200 diameter, six pipes are used for the DN100 diameter, one pipe is used for the DN125 diameter, one pipe is used for the DN500 diameter, three pipes are used for the DN600 diameter, and one pipe is used for the DN300 diameter.

[0039] Furthermore, an overflow pipe is provided inside the water tower body 100 , one end of the overflow pipe extends to the water storage portion 101 , and the water outlet at the other end extends to the base 102 .

[0040] Furthermore, the outlet pipes with diameters of DN500 and DN600 are welded with steel bars at the ports, and holes are opened on the sides of the ports. The steel bars are welded at the pipe ports to prevent people from falling into the pipes, and holes are opened on the sides to ensure the cross-sectional area of ​​water flow.

[0041] Specifically, the water outlet pipeline and the water inlet pipeline are both connected to flow meters of corresponding calibers.

[0042] It should be noted that in the specific design and layout process:

[0043] 1. The length of a single water pipe is 5 meters in principle. Straight pipes above the fifth floor can only be 3 to 4 meters due to the height limit of the water tower and the reasons of expansion joints and valves.

[0044] 2. The actual elevation of the water outlet casing on the water tower foundation is 200mm higher than the design elevation, so the position of the water outlet pipe is adjusted according to the actual elevation of the water outlet casing.

[0045] 3. Layout adjustment: In conventional design, the DN200 water outlet pipe 1 and the DN100 water outlet pipe 3 are too close to the ladder, so the positions of these two water pipes are adjusted.

[0046] 4. The expansion joint was originally designed to be at the bottom, but if it was at the bottom, the pipes at the top of the water tower would be subject to a relatively large force, so the expansion joint was adjusted to the top of the water tower.

[0047] 5. All water outlet elbows are welded on site.

[0048] 6. All water pipes are equipped with two valves, a manual flange butterfly valve at the top of the water tower and a manual wafer-type butterfly valve at the bottom of the water tower.

[0049] 7. The material of DN200~DN600 water pipes is changed from 304 stainless steel to Q235B, the thickness of DN200 pipe is changed to 6mm, and the thickness of DN500 and DN600 pipes is changed to 8mm.

[0050] 8. The total weight of Q235B steel pipe is about 39.91 tons (including flange), and the total weight of 304 stainless steel pipe is about 3.74 tons (including flange).

[0051] The utility model provides a water tower for ultrasonic water meter testing. Compared with the prior art, the utility model adopts a unified water storage column to discharge water, realizes the real-time operation of the water storage column through the instant water supply of water inlet pipes with different calibers, and adopts different caliber water outlet pipes to directly connect the water storage column to realize water discharge, solves the flow fluctuation caused by the instant distribution of water used by flow tables with different calibers at the same time, and improves the stability of the test.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
