PURPOSE: A centering valve for controlling the flow of wastewater is provided to constantly maintain the flow of wastewater discharging into a chemical treating bath by adjusting the opening and closing amount of a waste water transferring pipe. CONSTITUTION: A centering valve for controlling the flow of wastewater includes a sealed tube(10), a fence(11), and an expanding unit(14). The sealed tube is hollow and floats on the surface of water based on buoyancy. The fence surrounds a transferring pipe and is opened for the introduction of the transferring pipe. The expanding unit is in connection with the tube using a supporting unit(13) and is combined with a cone-shaped cap(15). The con-shaped cap opens and closes the outlet of the transferring pipe. The length of the expanding unit is capable of being adjusted. |
