The vertical check valve overcomes the spring resistance due to the pressure of the medium at the inlet end of the pipeline to open or close the valve. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the valve core to the valve seat and closes the valve to prevent the medium from flowing back, thus acting as a check. Vertical check valves are widely used in chemical, liquefied petroleum gas, fluid and other industries. Check valves can be divided into three types according to structure: lift check valve, swing check valve and butterfly check valve. Vertical check valve refers to a valve that relies on the flow of the medium itself to automatically open and close the valve disc to prevent the backflow of the medium. It is also called a check valve, a one-way valve, a reverse flow valve and a back pressure valve. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, prevent the pump and drive motor from reversing, and release the container medium. Check valves may also be used on lines supplying auxiliary systems where the pressure may rise above the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
The function of this type of valve is to only allow the medium to flow in one direction and prevent the flow in that direction. Usually this kind of valve works automatically. The valve disc opens under the pressure of fluid flowing in one direction. When the fluid flows in the opposite direction, the fluid pressure and the self-weight of the valve disc act on the valve seat to cut off the flow.
