An outfall valve structure of great water volume comprises a base and a hollow pipe. The base is integrally formed with a coupler and a cylinder, while the interiors of the coupler and the cylinder are communicable with each other. In addition, the cylinder is provided with an opening at one end surface, and a plug on the interior of the other end surface. A locking ring is provided at an appropriate position on the interior sidewall of the cylinder. Thereby, the hollow pipe is adapted to the communicable coupler and cylinder, and forms a large-sized outlet to ease the user to drink the liquid contained in the water bag.
