Description

Technical Field

[0001] The utility model relates to the technical field of vertical water meter verification, in particular to a device suitable for verifying vertical water meters in a horizontal water meter verification device. Background Art

[0002] Water meters are mandatory verification measuring instruments under key national management and must be installed and used only after passing the metrological verification. Water meters are classified according to the installation orientation and are usually divided into horizontally installed water meters and vertically installed water meters. A horizontally installed water meter refers to a water meter installed with the pipeline axis in the horizontal direction, and the dial of the water meter is marked with the "H" sign. A vertically installed water meter refers to a water meter installed with the pipeline axis in the vertical direction, and the dial of the water meter is marked with the "V" sign. The two types of water meters cannot be mixed and metrologically verified, that is, a horizontally installed water meter cannot be verified and used when installed vertically, and a vertically installed water meter cannot be verified and used when installed horizontally. Attached Figure 1 is a water meter verification device for horizontally installed water meters. Currently, the proportion of horizontally installed water meters exceeds 90%. However, despite the vast majority of horizontally installed water meters, there will still be a small number of vertically installed water meters that need to be verified. For testing units, purchasing a new vertically installed water meter verification device incurs significant expenses in terms of funds, site, personnel, etc. Moreover, due to the small number of vertically installed water meters, the device is idle for most of the time, resulting in serious waste of resources.

Both the front straight pipe section and the rear straight pipe section are vertically arranged.

[0005] Preferably, the rear straight pipe section moves up and down along the bracket.

[0006] Preferably, the two ends of the water meter are respectively threadedly connected to the front straight pipe section and the rear straight pipe section.
