The check valve is a valve used to prevent the backflow of the medium in the pipeline. It opens when the medium flows downstream and automatically closes when the medium flows backwards. It is generally used in pipelines that do not allow the medium to flow in the opposite direction, so as to prevent the reverse flow of the medium from damaging the equipment and parts. Do not cause the rotary pump to reverse rotation when the pump is stopped. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the discharge of the medium in the container.
