Abstract
Description
Technical Field
[0001] This utility model relates to the field of metrological verification equipment technology, specifically to an improved water meter verification device. Background Technology
[0002] As a key device for urban water supply metering, the accuracy of water meter calibration directly affects the interests of users and the revenue of water supply companies. Traditional water meter calibration often uses a single-position structure, resulting in low efficiency and high labor costs. In recent years, some water supply companies have introduced fully automatic series calibration equipment. However, due to the susceptibility of solenoid valves to interference from impurities, the difficulty and high cost of maintenance, and the fact that fully automatic equipment often uses a circulating water system, there is a risk of secondary water pollution from reinstalling old meters after random checks. Therefore, it is not suitable for the calibration and random checks of old meters.
[0003] Meanwhile, many companies still have a large number of old single-meter calibration benches that have been in service for more than ten years. These benches have structural aging problems such as water leakage and coaxial misalignment, but they still have the potential for renovation and utilization. How to upgrade the functions of old equipment in a low-cost way so that it can simultaneously have the ability to perform multi-meter calibration and original calibration has become a technical problem that the industry urgently needs to solve.

[0009] Furthermore, a water pump is also installed on the main body of the calibration platform at the customized water inlet connector.
[0010] Furthermore, the support guide rail is a stainless steel square tube, with its installation height coaxial with the inlet and outlet, and is fixed to the calibration table body by welding.
[0011] Furthermore, the adjustable clamp support includes a slide, a locking nut, a rubber washer, and a pressure arm, and the adjustable clamp support is connected to the support guide rail by an adjustable bolt.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] like Figure 1 As shown, an improved water meter calibration device in this embodiment includes a calibration platform body 2. Two support rails 7 are symmetrically installed on both sides of the top of the calibration platform body 2. An adjustable meter clamp support 8 is installed between the two support rails 7. A customized length compensation pipe 6 is installed on the adjustable meter clamp support 8. A water meter body 9 is connected between two adjacent customized length compensation pipes 6 through a water meter connector 10. There are five water meter bodies 9. A detachable straight pipe section 3 is installed on the calibration platform body 2 below the water meter bodies 9. By installing the adjustable meter clamp support 8, support rails 7, and customized length compensation pipes 6 on the original calibration platform body 2, and installing water meter bodies 9 between the customized length compensation pipes 6, the water meter calibration device can not only calibrate 4-5 water meters at the same time, improving efficiency by 400-500%, but also retains the original water meter calibration function, and is compatible with multiple uses such as sampling inspection, verification, and calibration.
[0023] like Figure 1 As shown, in this embodiment, a customized inlet connector 5 is installed on the calibration platform body 2 at the inlet end of the customized length compensation pipe 6, and a customized outlet connector 1 is installed on the calibration platform body 2 at the outlet end of the customized length compensation pipe 6. The water pump 4 is bolted to the calibration platform body 2. Both the customized inlet connector 5 and the customized outlet connector 1 are connected to the corresponding customized length compensation pipe 6. The water pump 4 is also installed on the calibration platform body 2 at the customized inlet connector 5. The customized inlet connector 5 can reliably connect the customized length compensation pipe 6 to the water pump 4, and the customized outlet connector 1 can connect the device to the water supply equipment.
[0024] like Figure 1 As shown, in this embodiment, the support rail 7 is a stainless steel square tube, and its installation height is coaxial with the inlet and outlet. It is fixed to the calibration table body 2 by welding. The adjustable clamp support 8 includes a slide, a locking nut, a rubber washer, and a pressure arm. The adjustable clamp support 8 can adapt to water meters of different diameters from DN15 to DN50 and provides radial limit and axial adjustment functions. The adjustable clamp support 8 and the support rail 7 are connected by adjustable bolts. The spacing of the adjustable clamp support 8 can be adjusted according to the length of different water meter bodies 9. The calibration table body 2 supports the simultaneous series calibration of 4-5 small-diameter water meters.
[0025] like Figure 1As shown, in this embodiment, the customized length compensation pipe 6 is made of a flexible connecting pipe, and a quick-connect fitting and a double O-ring are provided at the connection to prevent water leakage and facilitate disassembly and assembly. The water meter body 9 is connected to the water meter connector 10 by a quick-connect fitting. The detachable straight pipe section 3 is connected to the calibration platform through a pipe clamp. The interface accessories used in the calibration platform body 2 are universal with the existing fully automatic series water meter calibration platform, which can be universally purchased or replaced, reducing the modification cost.
[0026] The specific implementation process of this embodiment is as follows: When calibrating the water meter, firstly, an adjustable clamp support 8 and a customized length compensation pipe 6 are installed according to the diameter of the water meter body 9; then, the water inlet system is started to maintain a constant flow rate; next, the initial and final readings of each meter are recorded, and the error is calculated. Finally, if adjustment is required, the series structure is removed, and the single-meter mode is switched for verification and adjustment, thereby realizing the calibration of the water meter. Because this water meter calibration device retains the function of the original single water meter calibration platform, it can improve the calibration of the original calibration platform. An adjustable clamping support 8, a support rail 7, and a custom-length compensation pipe 6 are installed on the main body 2. At the same time, the water meter body 9 is installed between the custom-length compensation pipes 6. This allows the water meter calibration device to calibrate 4-5 water meters at the same time, improving efficiency by 400-500%. It also retains the original water meter calibration function of the equipment and is compatible with various uses such as sampling inspection, verification, and calibration. It is suitable for various scenarios such as sampling and recycling water meters, water meters submitted for inspection due to user objections, and retesting of new meters, thus improving the application flexibility of the calibration platform.
