High-stability low-pressure steam buffer tank

The utility model relates to the technical field of low-pressure steam buffer tanks, in particular to a high-stability low-pressure steam buffer tank which comprises a tank body, a ring seat capable of being used for connection is welded to the side, close to the air inlet end, of the inner circumference of the tank body, and a ring body capable of being used for auxiliary supporting is installed on the inner side of the ring seat in a screwed mode. A supporting plate used for auxiliary supporting is assembled on the inner side of the ring body, a disc seat used for connection is assembled on the face, close to the air inlet end of the tank body, of the supporting plate, and a supporting rod used for supporting is assembled on the surface of the bottom end of the disc seat; when steam enters the buffer tank, the hemisphere installed on the side, close to the air inlet end, of the interior of the buffer tank can divide the steam, so that the steam cannot directly rush into the inner side of the tank body and c
