Pipeline check valve is a valve that automatically opens and closes depending on the flow of the medium, and is used to prevent the medium from flowing back. It usually only allows the medium to flow in one direction and automatically closes in the other direction to prevent backflow. The structure of a pipeline check valve is relatively simple, usually consisting of a valve body and a valve disc. The valve disc can be spherical, disc-shaped, or conical. When the flow direction of the medium changes, the pressure of the medium will push the valve disc to close.
