Abstract
The utility model relates to a three-way rotary valve. The valve body of the three-way rotary valve is provided with three through holes which are distributed in the shape of 'T' in the same plane and a vertical hole which is perpendicular to the three holes plane. A cylindrical valve core is arranged in the vertical hole of the valve body. The valve core is provided with three through holes which are distributed in the shape of 'T' and are corresponding to the through holes on the valve body, and the diameter of the valve core holes is less than the diameter of the valve body holes. Each through hole of the valve body is respectively provided with a cambered surface sealing ring, the exterior-diameter and the interior-diameter of which separately are corresponding to the valve body through holes and the valve core through holes. The inner end face of the sealing ring forms a circular arc shape and is corresponding to the exterior round of the valve core. A hollow round nut is positioned in each valve body through hole outside the sealing ring and the hollow round nut is connected with each valve body hole through an external thread. The nut achieves sealing of the valve core holes by extruding the cambered surface sealing ring to abut on the outer round surface of the valve core. A valve handle is arranged on the upper part of the vertical hole on the valve body, extending from the hole of the valve cover and the gland to seal the sealing ring. The utility model can communicate and cut off any two of the three channels and can also cut off all the channels. The utility model has the advantages of reliable sealing performance and easy use.
