Nuclear Safety Air Duct Check Valve
Introduction:
The air duct check valve is a kind of valve whose opening and closing parts are circular discs and act by its own weight and medium pressure to block the backflow of the medium. It is an automatic valve, also known as a check valve, a one-way valve, a return valve or an isolation valve.
Features:
The characteristic is that the medium is allowed to pass through in the downstream direction and blocked in the reverse flow state. This type of valve does not need to be controlled by external force. Under the action of fluid pressure in one direction, the disc opens. When the fluid flows in the opposite direction, the fluid pressure and the self-weight of the disc Acts on the valve seat, thereby blocking the flow.
