The opening and closing parts of the high and medium pressure gate valve are gates. The movement direction of the gates is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the commonly used mode gate valves form a wedge shape. The wedge angle varies with the valve parameters, usually 5 °, and the large diameter is sometimes 3 °. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its processability and make up for the deviation of the sealing surface angle during processing. The plate is called a spring gate.
When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forcedly sealed, that is, when the valve is closed, the gate is forced to be pressed against the valve seat by external force to ensure the tightness of the sealing surface.
