Abstract
The utility model discloses a water leakage detector, which mainly consists of a casing, a signal acquisition device and a switch valve. Because a magnet is arranged inside a piston, an electromagnetic valve is arranged on the outer side of a water inlet horizontal tube chamber of the casing and is opposite to the magnet sleeved inside the piston, and the electromagnetic valve can flexibly detect change of positions of the magnet inside the piston and flexibly sense slight change of quantity of water flow. Once water pressure inside a water tube is changed, the piston can move to drive the magnet to move, and then the electromagnetic valve can transmit electric signal change due to movement of the magnet to an alarming device to alarm. In addition, the water leakage detector is provided with the switch valve consisting of a piston rod, a water channel nut, a reset handle and the like, a water leakage tube passage can be turned on or off through absorption and separation between the electromagnetic valve and the reset handle on the switch valve so as to turn on or stop the water flow, thereby being capable of effectively preventing water leaking further.
