Check the working principle of pneumatic valve

silencing check flow pneumatic valve refers to rely on the media itself, and automatically open, her breath valve, used to prevent the backflow medium pneumatic valve, also known as non-return pneumatic valve, pneumatic valve, one-way flow pneumatic valve, pneumatic valve and back pressure. Silencing check pneumatic valve belongs to a kind of automatic pneumatic valve, its main role is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium. Silencing check pneumatic valve can also be used to give the pressure could rise to more than the system pressure of the secondary system supply piping. Silencing check main can be divided into pneumatic valve swing silencing check pneumatic valve ( In accordance with the center of gravity rotating) With the sound check pneumatic valve lift ( Move along the axis) 。
silencing check pneumatic valve's role is only allowed to medium flows in one direction, the direction and stop the flow. This pneumatic valve is normally automatic work, in a direction of flow of fluid pressure, pneumatic valve open; In the opposite direction of fluid flow, the fluid pressure and pneumatic disc from the overlap of pneumatic disc on the pneumatic seat, thereby cutting off flow.
