Description

Under-pressure automatic valve-closing intelligent water meter

Technical Field

The utility model belongs to the technical field of water meters, and particularly relates to an intelligent water meter with an under-pressure automatic valve closing function.

Background

The intelligent water meter is a new type of water meter which uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to meter water consumption and make water consumption data transmission and settlement transaction. Thus, the total amount of water flowing through can be obtained by multiplying this constant volume by the number of revolutions of the impeller. And then the pointer on the mechanical water meter is read and metered by the electronic technology on the intelligent control part.

The intelligent water meter is generally arranged at the position where the water pipe enters a household, and the under-pressure of the water meter generally means that the water pressure is insufficient, so that the water meter cannot normally measure the flow. The existing building high-rise tap water has insufficient water pressure and small water yield, and the reasons of water consumption peak are eliminated, so that the high-rise water supply belongs to secondary water supply, and the water pressure of the secondary water supply is deliberately reduced because of the worry of pipe bursting caused by overhigh water pressure of some properties. When the water tap is opened, the water pressure is low, the water outlet is small, and the water pressure can be accumulated when one end of the water valve is closed, so that the water outlet is normal, but the water outlet cannot be kept beside the water pipe frequently in normal life, and the trouble of water is caused; the water supply pipeline is not closed under the condition of insufficient water pressure, water flow can continuously enter the pipeline in the home and the water meter, so that the pipeline is easy to leak water and the water meter is easy to have the condition of inaccurate counting, therefore, the utility model provides the intelligent water meter with the under-pressure automatic valve closing function, under the condition of insufficient water pressure, the water pressure change is automatically detected, the water inlet channel is automatically closed, water flow is prevented from continuously entering the home pipeline and the meter body, and water pressure is accumulated at the same time, so that the water pressure is conveniently used by subsequent families.
