シール構造。 A sealing structure for a gate valve in which a pair of valve body seats that are in sliding contact with both surfaces of a sliding valve body are installed in a state where they are prevented from coming off by a pair of seat rings. The valve box seats are each attached to a seal box in the valve box so as to be slidable in a direction toward and away from the sliding valve body, and a spring biases the both-side valve box seats in a direction toward the sliding valve body. A gate valve characterized in that a fluid introduction passage is formed in the seal box to introduce fluid in the valve box and bias the valve box seat in a direction close to the sliding valve body. Seal structure.
