Abstract
The utility model discloses a water larceny preventing device for a public water meter. The water larceny preventing device comprises a circuit board, a sensor and a bracket, wherein the sensor is welded on the circuit board; and the circuit board is arranged in the bracket. The water larceny preventing device is arranged on a dial of the water meter, other structures of the water meter are not changed, a signal of an interference magnet outside the meter is sensed by the sensor, a switch valve of the water meter is automatically turned off, the water meter stops supplying water, and only when the interference magnet does not exist, the water meter starts to normally supply the water, so the phenomenon of water larceny is avoided.
Description
Technical field
The utility model relates to a kind of public water meter preventing water burglary device.
Background technology
The water yield signal of present intellectual water meter all is to send through magnetic induction sensor, and this magnetic signal is easy to receive the interference of external magnetic field.A lot of users place above water meter and disturb magnet, disturb the transmission of water yield signal, and water meter can't be measured, thereby reach the purpose of water steathily.
The utility model content
The purpose of the utility model is to provide a kind of public water meter preventing water burglary device that can close the water meter valve automatically.
The public water meter preventing water burglary device that the utility model provides, it comprises circuit board, sensor, support, and said sensor is welded on the said circuit board, and circuit board is installed in the said support.
The utility model is installed on the index dial of water meter; Do not change other structure of water meter; Through the interference magnet signal of sensor sensing off-balancesheet, close the controlled valve of water meter automatically, make water meter stop to supply water; Only water meter ability normal water supply when disturbing magnet not exist has been avoided the generation of water phenomenon steathily.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the prior art constructions synoptic diagram.
Embodiment
As shown in Figure 1, the described public water meter preventing water burglary device of the utility model, it comprises circuit board 1, sensor 2, support 3, and sensor 2 is welded on the circuit board 1, and circuit board 1 is installed in the support 3.
The water yield signal of water meter all sends through magnetic induction sensor 4; Magnetic induction sensor 4 is installed in the both sides of minimum metering display disc on the water meter index dial; The support 3 of the utility model be installed in this minimum metering display disc above; Do not influence other structure of water meter, the sensor 2 in the support 3 can be responded to outside interference magnet.When external disturbance magnet existed, sensor 2 received and disturbs the controlled valve of cutting out water meter behind the magnet signal immediately through the circuit that is connected with circuit board 1, and when disturbing magnet not exist, the water meter normal water supply stops to steal the generation of water phenomenon.
Claims (1)
