ンドパツキンを設けたことを特徴とする緊急遮断弁。A valve rod attached to the valve body of an underground gate valve structure that opens and closes a pipeline by moving the valve body up and down is held in a raised position during normal times, and is released from the hold by an emergency signal transmitted in an emergency. In the emergency shutoff valve, the valve rod is lowered by extending the valve rod to the ground, and an opening/closing machine that moves the valve rod up and down is installed on the ground, and a lower end of the base of the opening/closing machine is installed on the ground. and a valve box of the underground gate valve, a hollow cover cylinder surrounding the valve body rod is disposed, and the holding of the valve body rod is released to the valve body rod within the cover cylinder. At the same time, a weight is attached to lower the valve rod, and while allowing the valve rod to move up and down at a position below the weight, the valve rod is shaft-sealed to allow water flowing in the pipe into the cover cylinder where the weight is located. An emergency shutoff valve characterized by having a gland packing to prevent the infiltration of water.
