Summary:The utility model relates to a vacuum floor drain for gravity flow and vacuum combined drainage system. A floor drain opening is arranged on the top of a floor drain water collecting box; and a vacuum tube passes through two DN40 vacuum diaphragm valves and then is inserted into the bottom of the floor drain water collecting box. When a water level reaches a certain degree, the two vacuum diaphragm valves are opened at the same time, and floor drain water is sucked into a vacuum pipeline system. By adopting the two DN40 vacuum diaphragm valves connected in series for drainage, the vacuum floor drain is large in caliber, and when one valve is blocked, a pipeline can be closed by the other valve, so that the vacuum system is prevented from being crashed by vacuum leakage, and the fault rate of a vacuum drainage system is reduced.
