Description
Technical Field
The invention belongs to the technical field of living appliances, and particularly relates to a water leakage protector.
Background
The wading equipment, electric appliances, water pipes, valves and other water devices used in our life at present are not provided with water flow monitoring control functions except that a monitoring control system is required to be arranged in some large-scale special water supply systems according to special requirements. Once these water consuming devices leak water, they are inconspicuous, which not only results in waste of a large amount of water resources, but also easily results in a costly accident. Therefore, the water leakage protection device with powerful functions and high automation degree can be provided, so that the water leakage protection device is convenient to assemble and use with the existing water-involved electric appliances, water pipes, valves and other water devices, and the functions of water monitoring and protection are realized.
Aiming at the problems, people design a water leakage protector, which is used for cutting off a pipeline or giving an alarm when an electric appliance leaks water, and the existing water leakage protector is usually directly connected with a valve rod by using an expansion sheet, and when the water leakage occurs, the expansion sheet absorbs water and expands, so that the pipeline is cut off. However, in such a water leakage protector, the stroke of the valve rod is determined according to the expansion degree of the expansion piece, and the expansion piece cannot be completely disconnected when the expansion piece is not sufficiently expanded, so that a potential safety hazard exists.
