In the rain and sewage diversion transformation of the combined system, the key control point is the setting of the intercepting inspection well. Through the intercepting inspection well, sewage enters the sewage system in dry days, and the intercepting multiple is controlled in rainy days, so that part of rainwater enters the sewage system, and most of rainwater is discharged into a downstream rainwater system. In the intercepting inspection well, a buoy is usually adopted for controlling the intercepting multiple at present. The float valve is also called as cut-off valve, flow-limiting valve and blind plate valve. The general principle is that the valve is controlled to open and close by the buoy, and the valve is opened and closed by the buoy along with the rise and fall of the water level to regulate and control the water flow.
