Technical Field

The utility model relates to the technical field of water leakage prevention devices, and particularly discloses a structure of a water leakage backflow prevention device capable of timely discharging water.

Background

The backflow preventer is to utilize the medium to flow through the pressure of the water-inlet check valve and the pressure of the water-passing head to be reduced due to mechanical resistance and the loss of the water-passing head, so that the inlet pressure is higher than the pressure of the water-discharging valve cavity by utilizing the medium to flow through the water-inlet check valve and the pressure of the water-passing head to be reduced due to mechanical resistance and the loss of the water-passing head, when the pressure difference between the inlet pressure and the pressure-discharging valve cavity is smaller than 0.02MPa, the medium is in a critical state of backflow, at the moment, the pressure at the upper part of the membrane is smaller than the water-discharging valve cavity and the spring resistance, the water-discharging valve is automatically opened, a large amount of air is discharged outside the backflow medium, and meanwhile, a large amount of air enters the valve body to form an air partition, so that the backflow of the medium is prevented.

The existing water-draining backflow preventer can prevent the medium from flowing backwards, but under certain conditions, the water-draining backflow preventer can possibly or fails to enable the medium to flow backwards, and due to the fact that a certain alarm reminding device is lacking, no one can find out in time when the backflow preventer fails to enable the medium to flow backwards, and therefore certain influence is generated on work.
