Structural features:
The disc of check valve is disc-shaped and rotates around the axis of the seat channel. Because the channel in the valve is linear and the flow resistance is smaller than that of the rising butterfly check valve, it is suitable for large-diameter occasions with low flow rate and constant flow change, but it is not suitable for pulsating flow, and its sealing performance is inferior to that of the rising butterfly check valve.
check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself, which is used to prevent the medium from back flow. It is also called check valve, one-way valve, counter flow valve and back pressure valve. The main function is to prevent the medium back flow, to prevent the pump and drive motor reverse, and to discharge the container medium. The check valve can also be used to supply the auxiliary system whose pressure may rise above the system pressure. Check valve can be divided into swing check valve (rotating according to the center of gravity) and lift check valve (moving along the axis).
The function of this type of valve is only to allow the medium to flow in one direction, and to prevent the flow in one direction. Usually, this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the fluid pressure and the dead weight of the valve disc act on the valve seat, thus cutting off the flow.
Application scope of American standard check valve:
American standard check valve is used in industrial pipeline as a device to prevent reverse flow of medium.
