A nonpower type chemical injecting equipment is provided to reduce installation cost substantially and obtain excellent durability by injecting a fixed quantity of chemicals into the storage tank in proportion to the flow rate of a fluid that flows into a storage tank and simplifying structure of the equipment. A nonpower type chemical injecting equipment comprises: a valve(30) which is installed on an injection hose(21), and on which a lever(32) is mounted to open or close rotationally the valve, the injection hose being connected to a chemical tank(20) above a storage tank(10); an injection quantity adjuster(40) mounted on the injection hose in a way that the injection quantity adjuster is positioned at the rear side of the valve; a plunger(50) which is formed in a vertical internal space of a water inflow pipe(11), and into which a fluid flows, the water inflow pipe being positioned in an internal space of the storage tank; and a piston weight(51) which is vertically movably installed in an internal space of the plunger and connected to the lever of the valve by a rope(52). |
