Detection method of fluid leakage and water leakage protector with application of detection method

Abstract

The present invention discloses a detection method of fluid leakage and a water leakage protector with the application of the detection method, belonging to the field of fluid leakage detection. According to the method, the velocity of a fluid is detected, and when the fluid has a speed and the velocity is constant and reaches a set time, fluid leakage is judged. The invention also discloses the water leakage protector with the application of the detection method. According to the invention, the velocity of the fluid is not related with the reliability and correctness of leakage judgment, according to the detection method, the fluid leakage with various reasons and various states can be timely found, the method is safe and reliable to use, and especially a small flow leakage can be effectively found and solved. According to the water leakage protector with the application of the detection method, the technical problem that an existing leakage protector can not detect small flow leakage is solved, the problem of water resource waste caused by forgetting to turn off a faucet can be effectively solved, and the water leakage protector can be widely applied to a household water pipeline, a water meter, a water purifier and the like.

Description

technical field [0001] The invention relates to a fluid leak detection method, more specifically, to a fluid leakage detection method and a water leakage protector using the detection method. Background technique [0002] In recent years, with the improvement of living standards, the use of domestic water and gas has become more and more popular. In the transportation pipelines of these fluids such as water and gas, fluid leakage occurs from time to time. If such leakage cannot be found in time, Not only will it bring inconvenience to life, but it will also waste resources and bring property losses. Seriously, it will even cause safety accidents. For example, indoor water leakage will easily soak furniture and floors, and it will also cause circuit safety problems; It is a safety issue that is likely to cause a fire. Leakage of domestic water is the most common leakage of these fluids. There are also some protection products for detecting water leakage on the market, which ...

Although this method can make the formulation of the limited flow rate more in line with the law of water use, there are still defects in the detection of "exceeding the limited flow rate", especially the inability to detect small flow leakage

[0005] Another example is Chinese Patent Application No. 201010534091.9, the date of publication of which is May 23, 2012, and the name of the invention is: a water leakage detection and control system and method used in conjunction with a water purifier, and the detection method of the application Therefore, judging whether the flow rate, pressure or flow rate of the water in the water inlet pipe conforms to the set water flow rate, pressure or flow rate change rule, and it is still possible to judge water leakage by using the flow rate or flow rate to exceed the set flow rate or flow rate. Realize the detection of small flow water leakage
