| description | A gate valve that opens or closes opening parts of a valve box with a valve plate includes a valve rod that moves upward or downward and tilt inside the valve box; a drive mechanism that moves the valve rod upward or downward by a predetermined stroke and tilts the valve rod; a stopper mechanism that includes a spring return type stopper pin, and in which, when compressed air is supplied, a pin rod of the stopper pin moves forward in a horizontal direction, and a cam plate connected to the valve rod or a load receiving roller attached to the cam plate collides with the pin rod to regulate an upward movement of the valve rod. When the supply of the compressed air is stopped, the pin rod moves backward in the horizontal direction due to a reaction force of the spring, so that the cam plate or the load receiving roller does not collide with the pin rod and the regulation on the upward movement of the valve rod is released; and a vibration reducing device that reduces vibration. |
