PURPOSE: An injector with function of controlling concentration of chemicals by controlling flow rate of inflow water is provided to feed chemicals having constant concentration into regeneration solution even if flow rate and pressure are changed when restoring ion exchange resin in an ion exchange equipment. CONSTITUTION: The injector comprises an inflow water flow rate control means comprising a plurality of blades(601) having the same shape formed in a rotary switch type at an inflow port into which regeneration water is supplied, and drop arms(602) fixed to blade shafts rotationally projected to an upper part of an injector first body with the blade shafts being fixed to the blades; an apparatus driving means comprising a plurality of adjusting links(609) fixed to one side of the plurality of drop arms, a blade driving gear(606) rotationally inserted into an injector second body with the blade driving gear being fixed to second supports(611) fixed to the other side of the plurality of adjusting links, and a driving motor(620) fixed onto an upper surface of the injector second body with the driving motor being axially connected to a motor gear connected to the blade driving gear by gear; a chemical concentration measure means comprising a concentration measure sensor(630) connected to a discharge part of the injector second body, and a concentration indicator(631) that is electric signally connected to the concentration measure sensor; and an electronic controller(700) that is electric signally connected to the concentration indicator of the chemical concentration measure means and the driving motor of the apparatus driving means to operate the driving motor according to values of the concentration indicator.
