Working principle of gate valve
2025-10-23
The working principle of the gate valve is based on the linear motion of the gate valve along the vertical direction of the flow of the medium in the valve body to realize the opening, closing or adjusting of the medium. When the valve stem is rotated by a flywheel, engine or other transmission mechanism, the gate is raised or lowered. When the gate is fully raised, the medium can pass through the valve smoothly, at this time the valve is in a fully open state; when the gate is lowered and tightly attached to the valve seat, the sealing surface between the two will match each other to prevent the medium from passing through the valve, at this time the valve is in a fully closed state.
