The invention discloses an overflow valve for isolating air. The overflow valve comprises an overflow body, a buoy and a sealing piece. A cavity is formed in the overflow body, and a water inlet pipeand a water outlet pipe communicated with the cavity are arranged at the top and the bottom of the overflow body respectively. The buoy is arranged above the overflow body, a guide column is fixedly arranged at the bottom of the buoy, a guide sleeve used for limiting the guide column in the radial direction is fixedly arranged in the overflow body, and one end of the guide column penetrates through the guide sleeve and extends into the cavity. The sealing piece is fixedly arranged on the bottom of the guide column, and the bottom of the sealing piece is in sealing fit with the top of the drainage pipe. Under normal circumstances, the sealing piece is in sealing fit with the top of the drainage pipe due to the gravity effect of the buoy, so that the drainage port of the drainage valve is isolated from outside air, the outside air cannot enter the drainage port from the water inlet pipe, the drainage port is almost in a full-pipe water state, and the drainage speed is greatly increased through the siphonic effect; and when the water level exceeds the buoy by a certain height, the buoy floats upwards, and the sealing piece is separated from the drainage pipe sealing face to achieve overflowing.
本发明公开了一种隔离空气的溢流阀，包括溢流本体、浮筒和密封件。溢流本体内部开设有空腔，溢流本体顶部和底部分别设有与空腔相连通的进水管和排水管。浮筒设在溢流本体上方且底部固设有一导柱，溢流本体内部固设有用于对导柱进行径向限位的导向套，导柱的一端穿过导向套并伸入空腔内。密封件固定在导柱底部，密封件底部与排水管顶部密封配合。正常情况下，密封件因浮筒的重力作用与排水管顶部密封配合，隔离了排水阀排水口与外界空气相通，外界空气无法从进水管进入到排水口内，排水口几乎处于满管水状态，通过虹吸效应使得排水速度大幅提高；当水位漫过浮筒一定高度时，浮筒上浮，密封件与排水管密封面脱离实现溢流。
