Claims

[Scope of Claim for Utility Model Registration] (1) A valve rotatably connected to a water supply pipe, in which an inflow channel and an outflow channel whose center lines intersect perpendicularly, and an intersection between the inflow channel and the outflow channel The center line of the inflow channel and the center of the outflow channel pass through the intersection of the valve chamber in the position where both channels are open, and the center line of the inflow channel and the center line of the outflow channel. A valve body having a stem hole having a center line perpendicular to the line and opening into the valve chamber, and an end portion of the valve body on the inflow flow path side is fitted to one end so as to be rotatable while maintaining watertightness. a water supply pipe connecting member whose end is connected to the water supply pipe; a ball having an L-shaped through hole; a ball seat in which the ball is mounted in close contact with the valve chamber to seal between the ball and the valve body; A rotatable valve in the form of an angle ball valve, comprising a stem that is inserted into the stem hole, has one end non-rotatably connected to the ball, and has a lever handle attached to the other end. (2) A valve rotatably connected to a water supply pipe, in which an outer circumferential groove for an O-ring and an outer circumferential groove for a split ring are formed from the outer end surface side on the outer circumferential surface of the end of the valve body on the inflow channel side, A substantially annular water supply pipe connecting member in which approximately half of the hole has a female thread that is screwed into the water supply pipe, and approximately the other half of the hole has a cylindrical inner surface into which the end of the valve body on the inflow channel side is inserted,
An inner circumferential groove for a split ring having a depth into which the split ring divided into a plurality of pieces is completely immersed is formed on the inner surface of the cylinder, and the number of split rings opened into the inner circumferential groove for the split ring is divided into a plurality of pieces. A number of threaded holes equal to the number of holes are formed radially through the O-ring, an O-ring is installed in the O-ring outer circumferential groove, and a split ring divided into a plurality of pieces is immersed in the split-ring inner circumferential groove to form a water supply pipe connecting member. A freely rotatable angle ball valve type in which the end of the inlet flow path side of the valve body is inserted into the cylindrical inner surface of the cylinder, a small screw is screwed into the screw hole, and the split ring is also fitted into the outer circumferential groove for the split ring. valve. (3) Form an O-ring outer circumferential groove and a split ring outer circumferential groove from the outer end side on the outer circumferential surface of the end of the valve body on the inflow channel side, and form a female thread in approximately half of the hole to be screwed into the water supply pipe. A substantially annular water supply pipe connecting member having a cylindrical inner surface into which the end of the valve body on the inflow channel side is inserted into the remaining half of the hole,
An inner circumferential groove for a split ring having a depth into which the split ring divided into a plurality of pieces is completely immersed is formed on the inner surface of the cylinder, and the number of split rings opened into the inner circumferential groove for the split ring is divided into a plurality of pieces. A number of threaded holes equal to the number of holes are formed radially through the O-ring, an O-ring is installed in the O-ring outer circumferential groove, and a split ring divided into a plurality of pieces is immersed in the split-ring inner circumferential groove to form a water supply pipe connecting member. 2. The angle ball valve according to claim 1, wherein the end of the valve body on the inflow channel side is inserted into the cylindrical inner surface of the valve body, and a small screw is screwed into the screw hole so that the split ring is also fitted into the split ring outer circumferential groove. Type of rotatable valve.
