Working principle of the knife gate valve
The gate valve is a type of valve that controls the flow of fluids by moving a gate up and down. Its working principle involves using a driving mechanism (manual or pneumatic) to move the gate in a straight line perpendicular to the direction of the fluid flow, thereby opening or closing the valve. When the gate is fully raised, the fluid passage is unobstructed; when it is fully lowered, the fluid passage is blocked. The edge of the gate in a gate valve is usually designed with a sharp cutting edge, which allows it to cut through impurities or fibers in the fluid, making it suitable for use in applications involving solid particles or viscous media.
