Claims

[Claim for Utility Model Registration] A water pipe seal that seals water before installing a faucet by screwing the threaded part provided on the bottom side of the tip of a generally cylindrical plug with a bottom into the elbow of the water pipe. In the plug structure for water, the above-mentioned plug includes an outer plug that has a threaded portion for the elbow, and an inner plug that is inserted into the inner cavity of the outer plug from an opening on the proximal side and is screwed and movable back and forth. This outer plug consists of an air bleed hole that penetrates toward the inner space in the approximate center of the bottom of the tip, a valve hole at the end of the air bleed hole on the inner space side, and a valve hole that extends from the valve hole to the proximal end. and a groove for removing the outer plug, which is formed in the vertical wall of the stepped portion on the proximal side of the internal threaded portion and facing the inner cavity, and further includes a sealing portion in the threaded portion. In order to accommodate the different inner diameters of each water pipe, the inner The plug has a tapered valve portion at the tip, an external threaded portion provided on the proximal end side of the valve portion at a portion corresponding to the internal threaded portion of the outer plug, and an inlet that spans the inlet between the valve portion and the external threaded portion. A plug structure for water sealing water pipes, characterized in that it has outlet ports on the proximal end side of the outer threaded portion, and a bypass passage passing through the inner plug body.
