摘要： The key part of a guide float valve plate--the float valve is disclosed. The object of the invention is to provide a parent-subsidiary guide float valve which has small pressure drop, high plate flux, high operation flexibility and can maintain high efficiency within a wide change range of the gas phrase load. The technical proposal of the invention is that: a parent-subsidiary guide float valve, of which the parent valve is a plane configure which is symmetrical with axial line thereof, the axial line directs toward overflow weir along the liquid flow, and the parent valve has at least two valve legs, the front valve leg length is longer than the back valve leg length, and when the parent valve is completely opened, an included angle of 2-10 degrees between valve cover and valve hole plate is opened toward overflow weir, while there is a valve hole on the parent valve with a subsidiary valve thereon, said subsidiary valve is a float valve with its area is small than that of the parent valve and its surround is paralleled with that of the parent valve, said subsidiary valve also has at least two legs, the front valve leg length is equal to or longer than the back valve leg length, when said subsidiary valve is completely opened, an included angle of 0-10 degrees between the subsidiary valve and the parent valve is opened toward overflow weir.
