The check valve is also called a reverse flow valve, and a back pressure valve This type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and is an automatic valve. The effect is to only allow the medium to flow in one direction and prevent the flow in the opposite direction. The load changes greatly, the opening and closing frequency is small, and when the input is turned off or on, the applicable period is long and the moving parts are not required to move. Its main function is to prevent backflow of the medium, prevent the pump and its drive motor from reversing, and discharge the medium in the container.
The check valve adopts a clip type. The butterfly plate has two semicircles, and the spring is forcibly resetting, and the sealing surface can be a body wear welding wear material or a lining rubber. The utility model has wide application range and reliable sealing.
