Abstract

A control valve includes a valve body and a valve seat, which is fixed at a bottom of the valve body, and has a roof with a spout thereon. Both side edges at front of the spout have intervals including a water inlet duct. The lateral arcs of the two inlet ducts are designed to taper the inlet duct. Also the upper sides of two inlet ducts connect with the roof, and the relative position on the roof of each duct has a limber hole to let water down into the inlet ducts. The two inlet ducts are used as an entry which penetrates the lateral arc to let each cold and hot water through into the ducts. An annular pad is outside of cold and hot water inlets to cover the ducts. The two intervals, which locate on the backsides of outlet, extend a ladder-shaped positioning pin respectively.
