Problems solved by technology

[0002] The commonly used wet water meter can move the impeller to measure only when the pressure difference between the inlet and outlet reaches a certain value. For this defect of the illegal residential water meter, the micro-opening water valve is used to steal water through the drip flow, causing a large amount of water resources to be stolen without compensation. Indiscriminate use, causing huge economic losses to the country

Abstract

A device for preventing water dripping from being stolen consists of wet rotary wing type of big water meter, single-way pressure check valve and wet rotary wing type of small water meter. It is featured as parallel-connecting two ends of water pipe being series-connected with small water meter separately with two ends of water pipe being series-connected by said check valve and big water meter through pipe fittings, setting two cavities of top and bottom on said check valve and sticking filter screen on water inlet end of small water meter.

Description

technical field [0001] The invention relates to an anti-drip water theft device. Background technique [0002] The commonly used wet water meter can move the impeller to measure only when the pressure difference between the inlet and outlet reaches a certain value. For this defect of the illegal residential water meter, the micro-opening water valve is used to steal water through the drip flow, causing a large amount of water resources to be stolen without compensation. Indiscriminate use has caused huge economic losses to the country. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defect, and provide a kind of anti-drip water theft device. [0004] The technical solution of the present invention is an anti-drip water theft device, which includes a water meter and a one-way pressure cut-off valve, and is characterized in that: the water pipe with the small water meter is connected to the water pipe connected in series...
