A water supply pipeline micro-leakage simulation device based on adhesive tape fixed water-soluble film and a method for calculating the required viscosity of the adhesive tape

Abstract

This invention discloses a device for simulating micro-leakage in water supply pipelines based on a water-soluble film fixed with adhesive tape, and a method for calculating the required adhesiveness of the tape. The device includes: a connecting pipe section, a fixing tape, and a water-soluble film. The connecting pipe section has a spiral fixing component at both ends connected to the circulation pipeline, and a hole in the middle serves as a leakage outlet. The fixing tape is cut into a square shape with a circular hole in the middle to allow space for the water to exit while placing the water-soluble film. The water-soluble film is a thin film with a certain structural strength that dissolves upon contact with water; it is cut into a circle to ensure the fixing effect of the tape. This experimental device can simulate micro-leakage close to that of a real municipal water supply pipeline wall rupture. Furthermore, by replacing the connecting pipe section, the shape and size of the leakage outlet can be controlled. The water-soluble film can simulate the gradual corrosion and rupture process of the pipe wall, and the device reduces the interference of artificial water hammer fluctuations on the leakage signal.
