Description

Automatic water leakage alarm backflow preventer

Technical Field

The utility model relates to a relevant technical field of pipeline accessory especially relates to an automatic alarm backflow preventer leaks.

Background

The drainage module of the backflow preventer drains water when the pressure difference is inverted, so that impact on the water meter is reduced. The existing drainage module is generally mechanical, the water leakage phenomenon of the drainage module cannot be found during drainage, and once the water leakage phenomenon occurs, the pressure difference judgment of a pipeline is influenced, and the waste of water resources is avoided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem, provide a leak automatic alarm backflow preventer, reduce the risk of leaking on the backflow preventer pipeline to can report to the police.

The utility model adopts the technical proposal that:

the utility model provides a leak automatic alarm backflow preventer, characterized by, includes backflow preventer and controller, the sluicing disk seat that sets up on the backflow preventer sets up the sluicing joint through the sluicing spring on the sluicing disk seat, sets up the pulse flowmeter on the sluicing joint, the pulse flowmeter is connected to the controller, the controller reports to the police according to the sluicing quantity abnormal conditions of pulse flowmeter.

Further, an electric switch valve is arranged in front of the pulse flowmeter and connected to a controller, and the controller closes the electric switch valve according to the abnormal water discharge condition of the pulse flowmeter.

Further, leak automatic alarm backflow preventer still includes sender and removes the end, the sender is connected to the controller, the sender passes through wireless network and removes the end communication connection, the controller will slual information transmission to remove the end through the sender.

Further, the wireless network is a 4G or 5G network.

The utility model has the advantages that:

(1) according to the drainage condition, judging the water leakage condition of the drainage module of the backflow preventer, and automatically closing the drainage module;

(2) wireless communication can be realized, and the condition of equipment can be known in real time;

(3) the product is stable and has long service life.
