Abstract
Disclosed is an anti-backflow device of drainage pipe. It includes a drainage pipe and an anti-backflow baffle joint. The drainage pipe is equipped with a drainage pipeline. The bearing tube and connecting bearing are installed on the lower edge on the right side of the drainage pipeline. The connecting bearing is equipped with an anti-backflow baffle and a threading hole. The connecting line, set between the anti-backflow baffle and the drainage pipe, links to the threading hole on the side of the anti-backflow baffle and ensure the opening angle of the anti-backflow baffle within a certain range for preventing that opening angle is too great to automatically cover the lid for the anti-backflow baffle when the external water level is too high.In recent years, the house owner often find that their household appliances are in the electrical failure caused by rain flowing backward and entering into the house overnight through the drainage pipe in the housing estate, and the accidents are discovered later. The device has advantages of a reasonable design, a simple structure and a low production cost, effectively preventing the liquid flowing backward.
