Diaphragm valve, as a special form of valve with cut-off function, plays a vital role in the fluid control system. Its opening and closing parts are carefully made of steel valve row and soft materials (such as rubber and fluorine plastic compound) to form a strong and flexible diaphragm. This layer of diaphragm cleverly separates the inner cavity of the valve body from the inner cavity of the valve cover, ensuring that the fluid can be effectively cut off or circulated under certain circumstances.
In actual operation, when the fluid channel needs to be cut off, the operator only needs to operate the handwheel clockwise. As the handwheel is turned, the valve stem will move down accordingly. At this point, the valve will follow the action of the valve stem, driving the diaphragm down together. When the diaphragm is fully attached to the valve seat, the fluid path is cut off, achieving effective control of fluid flow.
Conversely, when it is necessary to open the valve, the operator only needs to operate the handwheel counterclockwise. With the rotation of the handwheel, the valve stem will move upward, and the disc and diaphragm will also rise. When the diaphragm is completely separated from the valve seat, the fluid path is reopened, allowing fluid to flow freely through the conduit.
Diaphragm valve design ingenuity lies in its unique way of truncation. Compared with the traditional cut-off valve, the diaphragm valve can produce less fluid resistance when cutting off the fluid, and will not cause too much disturbance to the fluid. In addition, the diaphragm valve has excellent sealing performance and can ensure that the fluid does not leak in the shut-off state, thereby improving the safety and reliability of the entire fluid control system.
In summary, the diaphragm valve plays an indispensable role in the fluid control system with its unique structure and superior performance. Whether in industrial production or daily life, it provides us with a convenient, effective and safe fluid control scheme.
