Integrated water-meter

Abstract

The invention discloses an integrated water meter that belongs to liquid measuring device. It includes meter shell, gauge outfit, and controlling valve. The inner cavity of the meter shell forms liquid common-use channel, several gauge outfits and the corresponding valve are fixed on the shell. Every upper water intake connects to the common-use cannel, and every down water outlet connects to the controlling valve. Separating and guiding device is set between the upper water intake and liquid common-use channel. The invention is easy to be machined, installed and maintained, and it has high sensitivity, convenience to use, etc.

Description

technical field [0001] The invention relates to a liquid metering device, in particular to an integrated water meter capable of centrally metering the water consumption of multiple users at the same time. Background technique [0002] In the prior art, the liquid metering control devices used in residences, dormitories, etc. are mostly single-meter metering control, such as tap water meters, hot water meters, direct drinking water meters and reclaimed water meters, etc. are directly installed in residential buildings in the form of a single meter middle. Although this single-meter measurement structure, which has been used for many years, is simple in structure and easy to produce, it increases the work intensity of water meter installers and meter reading managers, and causes frequent harassment to residents, making it very inconvenient to use. [0003] In order to solve the above problems, the inventor once disclosed a metering device capable of...

AI Technical Summary

Problems solved by technology

First, because the watch head and the pressurized watch cover of the watch head are all fixed in the installation hole on the inner wall of the watch case, and the watch case is formed by sand casting, so it must be processed by turning, planing and other processes. The mounting hole is finished, and a very small internal thread is processed at the outer opening of the mounting hole. Without suitable tools, machining is very difficult and expensive; Therefore, shrinkage, cracks and other phenomena often occur during the casting process and processing; thirdly, the fluid velocity distribution distortion and vortex problems that often occur when the upstream water inlets of multiple meter heads are connected to the same main water inlet pipe are not considered. , which will seriously interfere with the measurement accuracy of the meter head
