Water leakage protection device and water purification system adopting same, and water leakage prevention method of system

Abstract

The invention discloses a water leakage protection device and a water purification system adopting the same, and a water leakage prevention method of the system. The water leakage protection device comprises an electric control board, an electronic control valve and a sensor, wherein the electronic control valve and the sensor are arranged in an internal waterway of the water leakage protection device, and are electrically connected to the electric control board; signals collected by the sensor are on-off control signals of the electronic control valve. The water leakage protection device provided by the invention has a simple structure, and can accurately judge water leakage in real time in a downstream pipeline on the basis that the structure that the signals collected by the sensor are used for controlling the on and off of the electronic control valve, so that water leakage can be quickly treated, expansion of water leakage accidents can be effectively limited, and water leakage can be terminated in time.

Description

technical field [0001] The invention relates to a water leakage protection device, a water purification system using the device and a water leakage prevention method for the system. Background technique [0002] The applicant had previously applied for a patent application entitled "An Anti-leakage Water Purifier", which included the first water inlet valve, filter element, water leakage detection device and electrical control system. The first water inlet valve is arranged on the water inlet pipeline of the filter element, and the water outlet of the filter element is connected to the inlet side of the water tap. The water leakage detection device is arranged on the water inlet pipeline or the water outlet pipeline of the first water inlet valve. The electric control system is electrically connected with the first water inlet valve and the water leakage detection device. The electrical control system is provided with a control module capable of processing the signal detec...

Problems solved by technology

[0003] This scheme uses the water pressure in the pipeline and the water flow time parameters to judge the leakage. When the leakage flow is small, the water pressure in the pipeline will basically not change. Therefore, this scheme cannot judge the situation of microleakage or slow leakage.

In addition, because the scheme does not use flow signals, it cannot be quickly judged for large-flow leakage accidents (such as burst pipes or tanks), but can only be detected after a large amount of water leaks.

In addition, for different types of water purifiers, the normal primary water output and water output duration vary greatly (such as ultrafiltration and reverse osmosis water purifiers), this program uses a unified normal primary water output and water output duration It is also unscientific to measure, and it will also cause a large amount of water to be discovered or lead to misjudgment
