The rubber flap check valve is also called a check valve or a check valve. Its function is to prevent backflow of the medium in the pipeline, prevent the pump and its drive motor from reversing, and discharge the medium in the container. The rubber flap check valve is mainly suitable for horizontal installation of the water supply and drainage system, and can be installed at the water outlet of the pump to prevent backflow and water hammer damage to the pump. It can also be installed on the bypass pipe of the water inlet and outlet pipes to prevent the water from flowing back into the water supply system. Check valves are generally suitable for cleaning media and should not be used for media containing solid particles and high viscosity.
