The present invention relates to a chemical injection apparatus, and, more specifically, to a chemical injection apparatus for supplying chemicals formed by injecting chemicals to the water supplied to a water supply pipe. The present invention relates to a chemical injection apparatus capable of being easily constructed on a water supply pipe, which comprises a main body; a chemical injection pump installed within the main body to inject the chemical within a chemical storage tank installed outside the main body to a water supply pipe, and having a chemical injection pipe having one side connected to the chemical storage tank and the other side connected to the water supply pipe; a motor operated in gear with the chemical injection pump and controlling the rotational speed to control the injection amount of the chemical; a control unit electrically connected to the motor and controlling the operation and the rotary speed of the motor; and a pressure detection sensor detecting the pressure within the chemical injection pipe, and electrically connected to the motor so as to allow the chemical to be injected to the chemical injection pipe only when water flows within the water supply pipe. |
