Intelligent fluid leakage protection device and control method thereof

Abstract

The invention discloses an intelligent fluid leakage protection device and a control method thereof. The intelligent fluid leakage protection device is characterized in that a V-shaped pipe section isarranged in a shell, an ultrasonic assembly is arranged in the V-shaped pipe section, and a reflector at the tip of the V-shaped pipe section reflects signals emitted by an ultrasonic generator to anultrasonic receiver, so that water flow rate and water flow time are recorded, and the ultrasonic assembly transmits data to a control module. According to the device and the method, when it is detected that the water flow rate and the water flow time reach a certain percentage range of a set value, the control module controls a driving block to drive a valve rod of a valve to rotate, so that theflux of the valve is obviously reduced, and a water using end enters a small-flow mode; if a user continues to use water and the water flow rate or the water flow time does not reach the set value, the water using end is closed, and the control module zeros out data measured by the ultrasonic assembly; and if the user continues to use the water and the water flow rate or the water flow time reaches the set value, it is judged that the water leakage occurs, and the control module drives the driving block to drive the valve rod of the valve to completely close the valve.

Description

technical field [0001] The invention relates to an intelligent fluid leakage protection device and a control method thereof, belonging to the technical field of fluid leakage protection equipment. Background technique [0002] Water and electricity are the necessary conditions for every home. There is an air switch to ensure the safety of electricity during use. There is no good solution for the safe use of water. , A device that can automatically cut off the water flow from the main water inlet pipe. In the prior art, a mechanical water leakage protector is usually used. This kind of water leakage protector has poor precision, many faults, and reliability cannot be guaranteed, and cannot well solve the loss caused by water leakage. Contents of the invention [0003] The purpose of the present invention is to provide a highly stable, safe, reliable and durable intelligent fluid leakage protection device, which can effectively solve the problem of water leakage in the proc...
