Water leakage detection protection method

Abstract

The invention discloses a water leakage detection and protection method. The water leakage detection and protection method comprises the following steps: setting a moving part inside a water inlet pipe, and setting a sensing device for detecting the movement of the moving part at a corresponding position; when the sensing device senses When the time when the moving parts continue to rotate or the time when the position deviation continues exceeds the first preset time, the valve on the water inlet pipe is controlled to close; after the valve is closed, the pressure change of the water inlet pipe is detected within the second preset time , if the pressure continues to drop and / or the pressure drop exceeds a preset value, keep the valve closed, otherwise control the valve to open. According to the water leakage detection and protection method of the present invention, whether the water inlet pipeline leaks is judged by detecting the liquid flow time in the pipeline and the liquid pressure in the pipeline successively, and correcting the previous detection results with the subsequent detection results, effectively This prevents the user from being misjudged that the water inlet pipe is leaking due to excessive water use time.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water leakage detection and protection method. Background technique [0002] With the improvement of people's living standards, more and more people choose to install a leak protector in the water inlet pipe at home to detect whether there is water leakage in the water inlet pipe at home. At present, there is a water leakage protector on the market that judges whether there is water leakage in the water inlet pipe based on the continuous flow time of the liquid in the pipe. The detection method is as follows: when the liquid flow time in the water inlet pipe exceeds the preset value, the water leakage The protector will judge that water leakage occurs in the water inlet pipe and then close the valve in the water inlet pipe. When the user needs to use water for a long time in cleanliness or other circumstances, only judging based on the continuous flow time of the liqui...

Problems solved by technology

When the user needs to use water for a long time in cleanliness or other circumstances, only using the time of continuous flow of liquid in the water inlet pipe as the basis for judgment may misjudge that the water inlet pipe is leaking, and then closing the valve will affect the user's normal water use
