| description | The invention belongs to the technical field of valves, and discloses a gate valve, comprising: a valve body provided with a flow channel cavity and a control cavity, the flow channel cavity extending in the X-axis direction, and the control cavity extending in the Z-axis direction; the two valve plates are used for opening and closing the flow channel cavity, and the two valve plates are oppositely arranged in the X-axis direction and are close to each other; the pneumatic device extends into the valve body and drives the two valve plates to reciprocate between a first position for closing the runner cavity and a second position for opening the runner cavity; and the ball body is clamped between each valve plate and the pneumatic device and can roll in the Z-axis direction, and when the valve plates are located at the first position and the second position, the valve plates, the pneumatic device and the ball body are locked with one another. The two valve plates enable the ball to be clamped between the valv |
