Rotary handle for sanitation water valve

摘要

The handle (3) has a conical portion corresponding to a conical portion on a valve rod (5). The handle is held in place axially by a screw fastening (6) and has an annular shoulder (41). The shoulder has at least one conical surface (42) which fastens into an annular recess (51) with at least one corresponding conical surface in the valve rod. The annular shoulder is formed on a sleeve (4) which is fixed firmly to the handle. An axial protrusion (31) is formed on the outer surface of the handle which works with a fixed stop (14) on the valve housing (1) to limit the rotation of the handle.
