Zusammenfassung:The utility model provides a novel combined type exhaust valve, and belongs to the field of air valves. The novel combined type exhaust valve comprises a main valve, a trace exhaust valve and an air supply channel, and a first floating piece is arranged in the main valve so that the exhaust channel of the main valve can be closed when the liquid level exceeds the liquid level line of the first main valve; the trace exhaust valve is connected with the main valve, and meanwhile, a second floating piece is arranged in the trace exhaust valve, so that an exhaust channel of the trace exhaust valve is closed when the liquid level exceeds a liquid level line of the trace exhaust valve; one end of the air supply channel is connected with the main valve, and the other end of the air supply channel is connected with the trace exhaust valve and used for maintaining pressure balance in the novel composite exhaust valve. According to the utility model, the air supply channel is additionally arranged between the main valve
