Intelligent full-flow-point full-automatic water meter calibration apparatus

Abstract

The invention discloses an intelligent full-flow-point full-automatic water meter calibration apparatus, comprising a water pipeline system and a water meter fixture; a water tank (11) of the water pipeline system is communicated sequentially with a water pump (12), a filter (13) and a main water supply pipe (14), the main water supply pipe (14) being communicated with a total outflow pipe; a branch inflow pipe (21), a piston hydraulic meter and a branch outflow pipe (22) are parallelly connected with the main water supply pipe (14); an outlet of the total outflow pipe is communicated respectively with an inlet of a high-precision outflow pipe (16), an inlet of a low-precision outflow pipe (17) and an inlet of a relief outflow pipe (18), and an outlet of the high-precision outflow pipe (16) is communicated with the water tank (11) through an inverted U-shaped pipe (28); the low-precision outflow pipe (17) is communicated with an inlet of a divider (30) through an L-shaped pipe (29), a first outlet of the divider (30) is communicated with a measuring tube (19), and the measuring tube (19) is rested on a scale (20). The intelligent full-flow-point full-automatic water meter calibration apparatus is suitable for household and public precision water meters.

Description

technical field [0001] The invention relates to the field of instrument and meter manufacturing, in particular to an intelligent full-flow point full-automatic water meter verification device. Background technique [0002] Water meter is one of the metering instruments used in the field of flow measurement, which is widely used and has many varieties and specifications. It plays an extremely important role in water supply and drainage flow calculation, water fee trade settlement, energy measurement and industrial and agricultural water process control. [0003] Before the water meter leaves the factory, it must be verified whether its reading is accurate. And the equipment that the prior art is carried out verification to water meter is relatively simple, and it generally comprises a water inlet connector and a water outlet connector, and a standard water meter part is connected in series on the water inlet connector. The worker manually plugs the water meter into the two c...

AI Technical Summary

Problems solved by technology

[0004] There are a series of problems in the water meter verification equipment in the prior art: 1. The degree of automation is too low, and it is basically manual operation. Manually connecting the water meter with the two joints is slow, inefficient, and labor-intensive; 2. It can only be connected one by one. The detection of water meters cannot be carried out in batches, which will further slow down the speed and reduce the efficiency; 3. The measurement results are not accurate, and the versatility of the equipment is poor, because the water meters are basically two t
