Claims

[Scope of Claim for Utility Model Registration] (1) The stem is rotatably connected to the water supply pipe, and the center line of the stem passes through the intersection of the center line of the inflow flow path and the center line of the outflow flow path of the valve body, and the inflow flow path A valve perpendicular to the center line of the outlet flow path and the center line of the outlet flow path,
The outer circumferential surface of the end of the valve body on the inflow channel side has a locking male screw, the inner circumferential surface of the end has a cylindrical inner surface, and the end surface has an annular plane, and is rotatable with the valve body. The water supply pipe connecting member to be connected has an outer circumferential groove for an O-ring on one side, a cylindrical outer surface that fits into the cylindrical inner surface, and an outer circumferential flange portion continuing therefrom, respectively,
A female thread is formed on the other side to be screwed into the water supply pipe, an O-ring is attached to the outer peripheral groove for the O-ring, the outer surface of the cylinder is fitted into the inner surface of the cylinder, and the inner peripheral flange and the locking groove are fitted. The outer circumferential flange of a locking member having a screw is loosely inserted between the inner circumferential flange and the annular plane, and the female locking thread is screwed into the male locking screw. Freely movable angle ball valve. (2) It is rotatably connected to the water supply pipe, and the center line of the stem passes through the intersection of the center line of the inflow channel and the center line of the outflow channel of the valve body, and the center line of the inflow channel and the outflow channel. The ball valve is perpendicular to the center line of the valve body, and the outer peripheral surface of the end of the valve body on the inflow flow path side has a cylindrical outer surface having an outer peripheral groove for an O-ring, and the inner peripheral surface of the end has a female thread for locking. The water supply piping connecting member integrally connected to the valve body has an inner cylindrical inner surface that fits into the outer surface of the cylinder on one side and an inner circumferential flange portion on the other side. A female thread is formed to be screwed into the water supply pipe, an O-ring is attached to the O-ring outer circumferential groove, the outer cylindrical surface is fitted to the inner cylindrical surface, and the outer circumferential flange and the locking female thread are connected to each other. The inner circumferential flange portion of a locking member having a locking member is loosely inserted between the outer circumferential flange portion and the annular plane, and the locking male screw is screwed into the locking female screw. Angle type ball valve.
