Industrial piston volumetric water meter

Abstract

The invention relates to the technical field of water meters, in particular to an industrial piston volumetric water meter. The volumetric water meter comprises a water inlet pipe and a water outlet pipe, a volumetric water meter body is arranged between the water inlet pipe and the water outlet pipe and at least comprises a lower shell, a water inlet and a water outlet are formed in the outer wall of the lower shell, the water inlet and the water outlet are communicated with the interior of the lower shell, the water inlet is communicated with the end of the water inlet pipe in a sealed mode,the water outlet is communicated with the end of the water outlet pipe in a sealed mode, the top of the lower shell communicates with a connecting threaded sleeve, a metering chamber mechanism comprises a metering chamber, the metering chamber is fixedly arranged in the lower shell, the interior of the metering chamber communicates with the water inlet and the water outlet, a piston is rotatably arranged in the metering chamber, a metering cover is arranged at the top of the metering chamber, a filtering device is embedded in the bottom of the metering chamber and comprises a fixed arc block,and an arc filter net is embedded on the surface of thefixed arc block. The metering is more accurate, and the sealing performance is better when the flange is used for connecting the water pipe.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to an industrial piston volumetric water meter. Background technique [0002] Water meters are a common item in daily life. Among them, volumetric water meters are widely used. Volumetric water meters measure the volume of the actual fluid passing through the water meter. The movement of volumetric water meters generally consists of a metering chamber, a piston, a partition, and a metering cover. The water is measured by the rotation of the piston in the cavity formed by the metering chamber and the metering cover; [0003] However, the existing volumetric water meters are not equipped with effective blocking equipment, so that there is a gap between the metering chamber mechanism and the lower casing, and part of the water is directly discharged from the drain without passing through the inside of the metering chamber, thereby affecting the metering accuracy of the water meter...

AI Technical Summary

Problems solved by technology

[0003] However, the existing volumetric water meters are not equipped with effective blocking equipment, so that there is a gap between the metering chamber mechanism and the lower casing, and part of the water is directly discharged from the drain without passing through the inside of the metering chamber, thereby affecting the metering accuracy of the water meter, and Most of the current volumetric water meters are connected to water pipes through flanges. When two flanges are connected by bolts, water often leaks from the gap between the connection positions, resulting in waste of water resources and increased costs. In view of this , we propose an industrial piston volumetric water meter
