摘要： The present invention discloses an inlet structure of water-storing keg float, comprises an inlet, an outlet pipe and a water-storing keg float with a storage tank, and the inlet is provided with a channel passing through the outlet pipe, and the channel is provided with a water-storing cavity and a guide hole, and the guide hole is communicated with the water-storing cavity and the outside wall of the outlet pipe. Because water-storing cavity is present, part of water from the inlet can be stored in the water-storing cavity because of gravity, and this part of water fully enters the storage tank of the keg float through the guide hole, and the keg float can be balanced effectively under different water pressure conditions, and the stability of the keg float is enhanced.
