The utility model provides a quantitative pressure regulating type outdoor fire hydrant, its characteristic is: the first is to install a liner and piston type valve in the fire hydrant valve body, between the corresponding parts of the diameter and valve bushing in the piston valve diameter and fixed on the inner wall of the valve body, the piston valve is inverted barrel, upper surface and bottom center hole and the connecting rod through bolts or wear pin fixed, the upper valve piston wall in open isosceles triangle hole, a rectangular hole in the lower part, the number of two kinds of holes should be greater than 1, between 1 and 6 is preferred; two is to install the pressure table, a threaded mounting hole aperture and universal pressure gauge thread on the upper part of the bolt body mounting handle is matched with the outer diameter, the pressure gauge installation handle is screwed into the inner and outer screw thread. The fire hydrant processing, installation and maintenance are simple and convenient, and the change process of the regulating pressure is quantified and visualized.
