Description

a water meter structure

technical field

The utility model relates to a water meter structure, in particular to a water meter structure.

Background technique

Most of the instruments for measuring water flow are the cumulative flow measurement of water. It is generally divided into two types: volumetric water meters and speed water meters. The accuracy of the former is higher than that of the latter, but it has high requirements on water quality, and it is easy to be blocked when there are impurities in the water. The latter has strong adaptability, is currently used in a wider range, and has a simpler structure. The meter that records the water consumption of tap water is installed on the water pipe. When the user uses water, the pointer or character wheel on the meter rotates to indicate the amount of water passing through.

In order to achieve the purpose of adjusting the measurement accuracy, the water meters on the existing market all adopt several (generally 1-3) adjustment holes at the bottom of the impeller box, and then install adjustment plates (for Block the hole size of the adjustment hole), and achieve the purpose of adjusting the accuracy of the water meter by adjusting the size of the adjustment hole, but such a structure also has the following defects:

1. The adjustment is inconvenient (it is necessary to manually adjust the position of the adjustment plate to adjust the size of the adjustment hole);

2. The adjustment accuracy is not high, because the adjustment holes that need to be adjusted are relatively small, and it is difficult to achieve the same adjustment degree of the adjustment holes of all water meters;

3. After long-term use, the accuracy of the water meter will be affected. Because of the existence of the adjustment hole at the bottom, when the water meter is in use, water will enter from the adjustment hole. The one-way water flow impacting the impeller will easily cause the impeller to appear eccentric, resulting in the measurement accuracy of the water meter. offset.

4. Increase the production cost. The addition of the adjusting plate increases the production parts and also increases the production cost.
