    摘要： In a gate valve including a valve plate connected to a valve plate mounting portion of at a tip end of a valve rod with a connecting plate and configured to open and close a communicating hole of a valve box with the valve plate, the valve plate includes a mounting hole, a joint flat surfaces coming into press-contact with each other, the valve rod includes a depressed-shaped joint shoulder portion, the joint shoulder portion is formed with an inclined surface configured to guide the valve plate in the direction in which the joint flat surfaces are brought into press-contact with each other, and the coupling plate couples the valve plate and the valve rod with each other.

    摘要： Between a driving base operated by an air cylinder and a lever member fixed to a valve shaft integral with a valve plate, a connecting mechanism for connecting the driving base and a lever member, capable of displacement, and a cam mechanism for tilting the lever member are interposed, and a stopper mechanism for stopping the lever member at an opposing position of the valve plate or a full-open position, and after the lever member is stopped by the stopper mechanism at the opposing position or the full-open position, the lever member is tilted by the cam mechanism so as to incline the valve plate and to press a valve seal to a valve seat portion or a wall face in the periphery of an opening.
