Water pipe micro-leakage monitoring device and micro-leakage monitoring method thereof

Abstract

The invention discloses a water pipe micro-leakage monitoring device and a micro-leakage monitoring method thereof. An impeller and an electromagnetic valve are disposed in a pipe. One end, adjacent to a water inlet, of the impeller is provided with a check valve having pores. A controller for controlling the on and off of the electromagnetic valve is disposed outside the pipe. A sensor for sensing the rotating state of the impeller is disposed on the impeller. The sensor and the electromagnetic valve are connected separately with the controller. The combination of the check valve with the pores allows the water flow speed generated due to micro-leakage or drip leakage to be increased, the micro-leakage monitoring is achieved with the cooperation of the impeller and the sensor, and in this way, misjudgments caused by transient flow movement due to shock or other special reasons are effectively prevented. Thus, the accuracy is improved, and the invention also has the advantages of simple structure, low cost and easy popularization.

Description

technical field [0001] The invention relates to the field of living appliances, in particular to a device and a method for monitoring water leakage of water pipe micro-leaks or drips. Background technique [0002] At present, there are various kinds of water-saving devices or systems at home and abroad, widely used in agricultural irrigation, industrial production, household water, etc., ranging from agricultural irrigation systems to small household flush toilets, reflecting people's water-saving ideas everywhere. Currently, there are many types of household water-saving devices, such as water-saving toilets, water-saving faucets, water-saving washing machines, and water-saving control systems. However, there is no special solution for the problems of water waste caused by dripping water that is not turned off tightly and that water taps are forgotten to turn off. A faucet that is not closed tightly can drain 1 to 6 cubic meters of water a month; a leaky toilet can drain 3...

Problems solved by technology

At the same time, the patent No. ZL201220296642.7 is an intelligent water pipe micro-leakage monitoring device, which monitors micro-flow water and realizes monitoring through water flow velocity. However, as far as the current technology is concerned, the water flow velocity of a small amount of water leakage is Difficult to detect, or the detection equipment requires advanced equipment with high precision and high cost, which will greatly increase the cost and is not suitable for the daily needs of ordinary families, and when the water pipe vibrates, it will also produce a small amount of water flow movement. In this case, This technology will completely lead to misjudgment and close the sluice, which will also bring inconvenience to use and even hidden safety hazards

And above-mentioned a kind of intelligent water pipe micro-leakage monitoring device, a kind of household water leakage prevention method and intelligent water meter need special water meter to carry out auxiliary operation, and water meter is installed by special mechanism, it is difficult to modify the structure of water meter, is not conducive to popularization or Invisibly increased costs
