[0043] The water inlet pipeline is provided with 3 water inlet pipelines with different diameters, which are DN125, DN200 and DN300 respectively; the water outlet pipeline is provided with 6 water outlet pipelines with different diameters, which are DN100, DN125, DN200, DN300, DN500 and DN600 respectively;
[0044] An overflow pipe is also provided inside the water tower body a-100, one end of the overflow pipe extends to the water storage part a-101, and the water outlet at the other end extends to the base a-102;
[0045] 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. 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.
[0046] It should be noted that in the specific design and layout process:
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 5. All water outlet elbows are welded on site.
[0052] 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.
[0053] 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.
[0054] 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).
[0055] The utility model provides a water tower design. Compared with the prior art, a unified water storage column is adopted for water discharge. The real-time operation of the water storage column is realized through the instant water supply of water inlet pipes with different calibers. Water outlet pipes with different calibers are directly connected to the water storage column to realize water discharge, which 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.
[0056] Among them, see Fig.13 —14, a group of flow stations b with different calibers all include a slide rail b-1 fixed to the ground, a pipe section rack b-2 is arranged on the slide rail b-1, the pipe section rack b-2 slides freely along the track direction of the slide rail b-1, and a pipe section b-3 is connected to the upper rack of the pipe section rack b-2;
[0057] And the slide rails b-1 are all arranged in a straight line;
[0058] The pipe section frame b-2 specifically includes: a fixed pipe section frame b-21 fixedly arranged at one end of the slide rail b-1, a fixed support frame b-22 fixedly arranged at the other end of the slide rail b-1, and a group of sliding pipe section frames b-23 movably arranged at the middle of the slide rail b-1;
[0059] The pipe segments b-3 are each composed of a group of unit pipe segments, which specifically include: a water inlet pipe b-31, a water outlet pipe segment b-32, and a group of movable water delivery pipe segments b-33 arranged between the two; wherein the water inlet pipe segment b-31 is fixedly arranged on a fixed pipe segment frame b-21, the water outlet pipe segment b-32 is fixedly arranged on a fixed support frame b-22, and a group of movable water delivery pipe segments b-33 is arranged on a group of sliding pipe segment frames b-23;
[0060] Each movable water delivery pipe section b-33 is provided with two sliding pipe section racks b-23 at the bottom;
[0061] A group of movable water delivery pipe sections b-33 are provided with different calibers, and the movable water delivery pipe sections b-33 with different calibers are fixedly connected through flanges with different calibers. A sliding pipe section frame b-23 is set at the bottom of each flange.
[0062] The utility model provides an ultrasonic flow measurement adaptive pipe section, which realizes the free sliding assembly of large-diameter pipe sections through the cooperation of a slide rail arranged at the bottom and a pipe section frame. Since the movable water delivery pipe sections of different diameters are connected through flanges, the movable water delivery pipe sections of different diameters can be freely disassembled, and the corresponding assembly of the diameters is realized with the help of the slide rail. Compared with traditional hoisting, the utility model has a simple and labor-saving structure, simple components and low implementation cost, and solves the problem that the existing large-diameter pipe section assembly and measurement operation is cumbersome and the cost is increased.
[0063] Among them, see Fig.15 —18, the reversing device c includes a reversing support frame c-100 fixedly set on the ground and a water bucket c-200 with an opening upward, a support platform c-101 is arranged on the top of the reversing support frame c-100, a group of vertical spherical bearings c-300 with a seat are symmetrically arranged on the upper surface of the support platform c-101 through a fixed frame, a group of embedded columns c-201 are fixedly connected on both sides of the water bucket c-200, and the embedded columns c-201 are correspondingly embedded in the corresponding vertical spherical bearings c-300 with a seat and can rotate freely, an opening is arranged on the surface of the support platform c-101, and a flow-bearing reversing box c-400 is fixedly connected to the lower surface of the support platform c-101, the flow-bearing reversing box c-400 is connected to the opening, a group of water outlets at the bottom of the flow-bearing reversing box c-400 are connected to water receiving boxes c-500 of different ranges, and a group of water receiving boxes c-500 are each provided with a scale c-600 of a corresponding range at the bottom;
[0064] The water bucket c-200 is in an inverted triangle shape, with both the upper and lower ends being open, and a water pipe c-700 is fixedly disposed above the upper opening of the water bucket c-200;
[0065] And the lower end of the water bucket c-200 opens out of the opening;
[0066] The bottom of the flow-carrying and reversing box c-400 corresponds to two water outlets, which are connected to two water receiving boxes c-500 with different measuring ranges and two scales c-600 with different measuring ranges;
[0067] A baffle c-401 is provided in the middle of the flow-bearing and reversing box c-400, and the baffle c-401 divides the flow-bearing and reversing box c-400 into two parts;
[0068] A group of pneumatic drive components c-800 are also fixedly and symmetrically arranged on the upper surface of the support platform c-101. The pneumatic drive components c-800 and a group of vertical spherical bearings c-300 are arranged perpendicular to each other. The pneumatic drive components c-800 include a group of pneumatic support frames c-801 fixed on the upper surface of the support platform c-101. A cylinder c-802 is fixedly arranged on the pneumatic support frames c-801 horizontally on the upper surface of the support platform c-101. The other end of the cylinder c-802 is movably connected to a cylinder straight connecting rod c-803. The other end of the cylinder straight connecting rod c-803 is movably connected to a reversing ring c-804. The reversing ring c-804 is fixedly connected to the bucket c-200 through a connecting rod.
[0069] And a flat flow plate c-202 is arranged inside the water bucket c-200.
[0070] During use, water flows from the water pipe c-700 into the water bucket c-200, flows out from the opening at the bottom of the water bucket c-200, flows into the corresponding flow channel of the flow-bearing and reversing box c-400, flows into the corresponding water receiving box c-500, and is weighed by the measuring scale c-600 set at the bottom.
[0071] When reversing is required, the pneumatic drive component starts, and the two symmetrical cylinders c-802 move, presenting a state of one end pushing forward and the other end pulling back. After the movement of cylinder c-802, it drives the cylinder straight-connecting rod c-803 to move, and the cylinder straight-connecting rod c-803 drives the reversing ring c-804 to move. Since the cylinder straight-connecting rod c-803 and the joints of cylinder c-802 and the reversing ring c-804 are all movably connected, it does not affect the movement of the overall reversing ring c-804, thereby driving the water bucket c-200 to achieve the corresponding reversing through the fixed connecting rod. As for the reversing angle, the user can adjust the movable range of the cylinder joint according to the actual situation.
[0072] The utility model provides a flow measurement pipe network commutator, which realizes automatic reversing of a water bucket through a pneumatic drive component in cooperation with a vertical spherical bearing with a seat. After flowing through the water bucket, water flows into a corresponding water receiving box from an opening at the lower end, and is measured again by a corresponding scale. Compared with the prior art method of pushing a water tank to achieve reversal, semi-automatic reversal is achieved, and the coordination between components improves the speed of reversal, solving the problem that the traditional method requires the scale at the water outlet to be pushed by a cart for replacement when replacing the scale, which is cumbersome and difficult to operate, and the frequent pushing may also cause damage to the metering component at the bottom of the scale.

[0074] The water bucket c1-300 is in the shape of an inverted fan arc, with an opening at the lower end;
[0075] The bottom of the flow-carrying and reversing box c1-400 corresponds to two water outlets, which are connected to two water receiving boxes c1-500 with different measuring ranges and two scales c1-600 with different measuring ranges;
[0076] A baffle is provided in the middle of the flow-bearing and reversing box c1-400, and the baffle divides the flow-bearing and reversing box c1-400 into two parts;

[0078] During use, water flows from the water pipe c1-200 into the water bucket c1-300, flows out from the opening at the bottom of the water bucket c1-300, flows into the corresponding flow channel of the flow-bearing and reversing box c1-400, flows into the corresponding water receiving box c1-500, and is weighed by the measuring scale c1-600 set at the bottom.
[0079] When reversal is required, the pneumatic drive component starts, and the two symmetrical cylinders c1-702 move, presenting a movement state in which one end pushes forward and the other end pulls back. After the movement of cylinder c1-702, it drives the cylinder direct-connecting rod c1-703 to move, and the cylinder direct-connecting rod c1-703 drives the water bucket c1-300 to move. Since the joints of the cylinder direct-connecting rod c1-703 and the cylinder c1-702 and the outer wall of the water bucket c1-300 are movably connected, it does not affect the movement of the entire water bucket c1-300, thereby achieving the corresponding reversal. As for the reversal angle, the user can adjust the movable range of the cylinder joint according to actual conditions.
[0080] The utility model provides a flow measurement pipe network reversing device, which realizes automatic reversing of a water bucket through a pneumatic driving component. After flowing through the water bucket, water flows into a corresponding water receiving box from an opening at the lower end, and is measured again by a corresponding measuring scale. Compared with the prior art method of pushing a water tank to realize reversing, semi-automatic reversing is realized, and the coordination between components improves the reversing speed, which solves the problem that the traditional method requires the measuring scale at the water outlet to be pushed by a cart for replacement when replacing the measuring scale, which is cumbersome and difficult to operate, and the frequent pushing may also cause damage to the metering component at the bottom of the measuring scale. At the same time, the reversing water bucket provided by the utility model adopts an inverted fan arc shape with an opening at the lower end, which prevents splashing of large-caliber flow.
[0081] The utility model provides a complete flow table for ultrasonic water meter testing. Compared with the traditional testing method, the complete flow table for ultrasonic water meter testing of the utility model has higher precision and stability, can more accurately test the performance of the ultrasonic water meter, and improve the testing efficiency.

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.
