The backflow preventer is a hydraulic control combination device that strictly limits the water in the pipeline to flow in one direction. It is developed based on the serious backflow pollution of tap water supply equipment, especially domestic drinking water pipelines, to prevent backflow from contaminating the water source. Its function is: Prevent the backflow of media in the pipeline under any working conditions to avoid backflow pollution. At present, backflow preventers are mainly divided into two categories: low-resistance backflow preventers and pressure-reducing backflow preventers.
Backflow preventer
The backflow preventer is a device used to prevent the backflow of fluids in pipeline systems. It mainly consists of two check valves and an intermediate chamber.
During operation, under normal circumstances, the fluid can smoothly pass through the check valves and flow forward. When a reverse pressure occurs, the two check valves cooperate with each other. The first check valve blocks most of the backflow. The intermediate chamber can relieve pressure and drain water, and the second check valve further blocks the remaining reverse water flow, thus effectively avoiding the backflow phenomenon. The backflow preventer is widely used in fields with high requirements for water quality and safety, such as drinking – water systems and fire – fighting systems, to ensure the one – way flow of fluids and the safety and hygiene of the systems.
