Abstract
A valve with a structure limiting of the turning angle of the valve knob includes a valve and knob installed on the valve. The valve contains a raised tube, which contains a globe valve brake axle protruding in the center; and the knob contains a connecting groove which can be affixed to the top of the globe valve brake axle. One side of the raised tube of the valve forms a section of fillister plane along the circumference, and two crosswise ends of the fillister plane form first and second blades vertically. The bottom of the connecting groove of the knob forms an expanded groove, and one side of the fillister plane forms an inner protrusion. The structure of the turning angle of the knob is completed concealed inside the knob.
