Description

Technical Field

[0001] This utility model relates to the technical field of water meter pressure measurement, and in particular to a water meter pressure measurement and water supply device. Background Technology

[0002] Water meters are widely used in industries such as tap water, heating, and chemical processing. Companies that manufacture water meters or metering departments need to verify the performance of these water meters according to the regulations formulated by relevant departments.

[0003] Existing water meter pressure testing and water supply devices, such as the fully automatic water meter calibration device disclosed in utility model patent application number 202021448098.4, mainly include a control console, a workbench, and a water supply device. In use, it is necessary to adjust the clamp size of the water meter clamp on the upper surface of the clamp support plate according to the size of the water meter to be calibrated, fix the water meter in the water meter clamp, and then adjust the vertical position of the clamp support plate to find the position where the interface of the water meter matches the interface of the electric valve and the interface of the flow detector. At this time, the water meter is connected to the electric valve and the flow detector through pipes.

[0004] However, most existing water supply devices supply water directly through water pumps, and the pipeline pressure is easily affected by the start and stop of the water pumps, which in turn affects the accuracy of water meter pressure measurement. Moreover, each time the water meter to be tested is replaced, it requires cumbersome disassembly and assembly, resulting in low work efficiency. Utility Model Content
