ABSTRACT:
A branched valve includes a main flow passage and a branch flow passage provided in a main body, a weir provided between the main and branch flow passages, and a valve disc which can contact with and come off from the weir and which selectively connects and disconnects the main and branch flow passages, wherein a branch flow entrance wall of the branch flow passage integrated with the weir has either a flat surface or a convex surface. The outer wall of the branch flow exit of the main flow passage may rise vertically from the outer wall of the main flow passage, and the side wall of the weir is located approximately on the center line of the main flow passage. The branch flow passage may be provided so that the center line thereof is located higher than the center line of the main flow passage. The valve disc may be a diaphragm.
