technical field

The utility model belongs to the field of water meters, in particular to a horizontally installed household quantitative discharge water meter.

Background technique

A water meter is an instrument used to measure water flow. The water meter measures the cumulative flow of water and records the water consumption of tap water. The water meter is installed on the water pipe. When the user releases water, the pointer or character wheel on the meter rotates to indicate the amount of water passing through. Common water meters on the market are generally divided into two types: volumetric water meters and speed-type water meters. Among them, volumetric water meters are also called quantitative discharge water meters. Volumetric water meters are more accurate than speed-type water meters, but they have high requirements for water quality. It is easy to be blocked by impurities.

The mesh size of the first filter net and the second filter net is smaller than the mesh size of the filtered net.

The beneficial effects of the utility model are:

1. The utility model filters the tap water through the water inlet interface filter device for the first time, the tap water is filtered twice through the first filter screen, the tap water is filtered three times through the intermediate filter screen, and the tap water is filtered four times through the second filter screen. Through quadruple filtration of tap water, the water meter is not easy to block;

2. Through the setting of the first check valve and the second check valve, when the water meter is reversed or the fluid is reversed, the first check valve and the second check valve play a role of check, and the water meter is not easily damaged;

3. The structure is simple and easy to manufacture;

4. The mesh size of the net before filtration is larger than the mesh size of the net after filtration, the mesh size of the first filter net and the second filter net is smaller than that of the net after filtration, and the dirt is intercepted in the filter device of the water inlet interface And between the first filter screen and the filter screen, the filter effect is good.
