Claims

[Scope of Claim for Utility Model Registration] (1) A valve box having an air supply port and an air supply/exhaust port formed on the opposite side of the air supply port, which is built into the valve box, and which is It is a slidable valve that blocks communication between the air supply port and the supply/exhaust port, and further includes a check valve portion (child valve) that allows gas to flow from the above-mentioned air supply port to the supply/exhaust port and prevents backflow. Valve body (parent valve)
, and a rapid valve that is provided in the valve box and is closed by the valve body that moves toward the supply/exhaust port, and is opened by movement in the opposite direction and communicates with the supply/exhaust port. In a quick exhaust valve configured with an exhaust port; A rapid exhaust valve characterized by having a recess having a size of the above, and a check valve provided in the cylindrical part of the recess; (2) A valve box with an air supply port and an air supply/exhaust port formed on the opposite side of the air supply port, which is built into the valve box and where the air supply port and the air supply/exhaust port communicate with each other. A valve body (master valve) that is slidable and has a check valve part (child valve) that allows gas to flow from the air supply port to the air supply/exhaust port and prevents backflow.
, and a rapid valve that is provided in the valve box and is closed by the valve body that moves toward the supply/exhaust port, and is opened by movement in the opposite direction and communicates with the supply/exhaust port. In a quick exhaust valve configured with an exhaust port; A quick exhaust valve is characterized in that: a check valve is provided on the box body; and the box body has fine irregularities on its inner wall surface;
