Claims

[Claims for Utility Model Registration] 1. A saddle portion having a branch socket which is clamped and fixed to a main pipe and has a flow path communicating with a branch port opened in the main pipe; a branch socket of the saddle portion; A branch plug device comprising: a branch plug communicating with a flow passage within the socket through a connecting tube having a flow passage formed therein; the branch socket has an inner circumference facing the opening; A cylindrical inner surface having a right cylindrical shape is formed, and an engaging inner surface is formed in the deep part of the cylindrical inner surface, and a male threaded portion is screwed on the outer periphery facing the opening, and the branch plug is connected. The cylinder has an engaging portion formed on its outer periphery facing the tip portion and fitted into the engaging inner surface of the branch socket, and is connected to the engaging portion and has a circumferential inner surface of the branch socket. A cylindrical surface portion is formed to be fitted into the cylindrical surface portion, and an O-ring is attached to the tip side of the cylindrical surface portion, and a retaining ring is attached to the inner side of the cylindrical surface portion, and the retaining ring is exposed from the branch socket of the connecting tube. A mounting structure for a branch plug, characterized in that a lock nut is tightened and fixed to the male thread on the outer periphery of the branch socket via the outer circumference of the branch socket. 2. The branch stopper mounting structure according to claim 1, wherein the engaging inner surface on the branch socket side has a regular polygonal shape, and the engaging portion on the branch socket side also has a regular polygonal shape. 3. In claim 1, the engaging inner surface on the branch socket side is provided with rib portions spaced at equal intervals in the circumferential direction, and has an engaging groove portion formed by the rib portions, and the engaging inner surface on the branch plug side The branch plug mounting structure has at least one engaging convex portion that fits into the engaging groove vertically provided from the lower end of the cylindrical surface portion. 4 A connection in which a branch socket in which a flow passage is formed that communicates with a branch port opened in the main pipe is directly fixed to the main pipe, and a flow passage is formed inside the flow passage in the branch socket. A branching plug device in which a branching plug is connected through a cylinder, and the branching socket has an inner cylindrical inner surface facing the opening and a right cylindrical inner surface on the inner periphery thereof, and the inner cylindrical inner surface An engaging inner surface is formed in the inner part of the connector, and a male threaded part is screwed on the outer periphery facing the opening, and the connecting tube of the branch plug is formed on the outer periphery facing the tip and is adapted to engage the branch socket. An engaging portion that is fitted into the inner surface is formed, and a cylindrical surface portion that is connected to the engaging portion and that is fitted into the cylindrical inner surface of the branch socket is formed. An O-ring is attached to the tip side and a retaining ring is attached to the inner side, and the lock nut screwed into the external thread of the branch socket is tightened and fixed through the retaining ring exposed from the branch socket of the connection tube. A branch stopper mounting structure characterized by: 5. The branch plug mounting structure according to claim 4, wherein the branch socket and the branch plug are made of the same material for a main pipe made of stainless steel.
