What is the working principle of American standard check valves
The working principle of American standard check valves is mainly based on the flow direction of the medium to control the opening and closing of the valve disc. When the medium in the American standard check valve flows in a specific direction, the valve disc opens under the thrust of the medium flow, and the American standard check valve allows the medium to pass through. When the medium flows back, the valve disc, under its own weight and the reverse thrust of the medium flow, tightly seals with the sealing surface of the valve seat, closes the valve, and thus prevents the medium from flowing back.
The American standard check valve is a type of automatic valve, and its basic function is to avoid medium backflow, prevent pump and driver motor flipping, and prevent container medium release in applications. In addition, it can also be applied as a safety protection device in situations where the working pressure may exceed the system pressure.
The valve disc of the American standard check valve is disc-shaped and rotates around the axis of the valve seat channel. The structural length follows the provisions of ANSIB16.10, and the flange connection size follows the standard of ANSIB16.5. Due to the streamlined design of the valve channel, the flow resistance is relatively small, making it particularly suitable for large diameter applications with low flow rates and infrequent flow changes.
When installing American standard check valves, the American standard gate valve manufacturer needs to ensure that the flow direction of the medium follows the arrow direction indicated on the product, otherwise the valve will not function properly. At the same time, in order to maintain the good performance of the valve and extend its service life, regular maintenance and inspection are also essential.
In summary, the American standard check valve effectively achieves the function of preventing medium backflow through its unique working principle and structural design, and plays an important role in various industrial occasions.
