Working principle

Cambridge backflow preventer series products are a hydraulic control combination device developed by our company, which is used to strictly limit that the pressure water in the pipeline can only flow in one direction when urban water supply and other units supply water to general pollution units. Its function is when siphon backflow and back pressure backflow occur in the water supply system, It can effectively prevent the medium with poor water quality at the outlet from flowing back to the inlet with better water quality, avoid the water pollution of domestic drinking water, and ensure the safety of domestic water supply, so as to achieve the purpose of avoiding backflow pollution.
