Inner guide multifunction digital water meter

Abstract

The invention relates to inner guiding multifunctional digital water meter adopted energy saving and green mechanical-electrical integration design. Its features are that it adopts dry type inner flow guiding, liquid crystal digital screen single display, and sets inner flow guiding and gravity valve eyelet-hole jetting dripping proof device, buoyancy force breather valve device, electromagnetism guiding valve device, and electrical effect transducer. It has the advantages of simple structure, small volume, light weight, long useful life, low failure rate, good stability etc. It can greatly increase water meter sensitivity and precision, control minimum flow rate at 0.003m3 per hour, breakaway flow rate at 0.003m3 per hour. Thus it can be widely used in varieties of cold water meter, hot water meter, heat energy meter, IC card intelligent meter, remote control water meter.

Description

technical field [0001] The invention belongs to the field of fluid control and metering, and relates to an energy-saving and environmentally-friendly electromechanical integration design, which can be widely used in various cold water meters, hot water meters, heat energy meters, IC card smart meters, and remote control water meters, and particularly relates to an internal meter. Conductive multifunctional digital water meter. Background technique [0002] At present, the water meters commonly used at home and abroad are all Voltmann water meters invented a hundred years ago. Although the materials have been improved and the accuracy has been improved over the years, their original structure has not been fundamentally changed. , there are defects such as low measurement accuracy, complex structure, large volume, unintuitive dial display, large starting flow, high mechanical failure, and mismeasurement of anhydrous air flow. my country is a country that lacks fresh water res...

Problems solved by technology

A small number of users take advantage of the shortcomings of traditional water meters, such as large starting flow and small flow, to steal water, causing losses to water supply units

In order to solve the problems of difficult meter reading and charging, major and medium-sized cities across the country have formulated IC card smart water meter promotion plans and one-card plans. The old-fashioned traditional water meter is used as the base meter, and a magnetic sensor, a single-chip microcomputer instrument compartment, an electric ball valve and a liquid crystal display device are installed. The IC card smart water meter produced has low measurement accuracy, low display accuracy, large starting flow rate, and leakage when the valve is closed. Large quantity, high power consumption, high failure rate, high cost and other shortcomings, it is difficult to promote and apply in a large scale
