Automatic washing function's pressure vessel has been increased

The utility model relates to a pressure vessel especially relates to an automatic washing function's pressure vessel has been increased, including overhead tank body, inlet tube, three -way pipe I, flushing pipe subassembly, control flap A, control flap B, buffer solution feed liquor pipe, its characterized in that: the intermediate junction on the top of overhead tank body sets up the flushing pipe subassembly, the lower extreme of inlet tube passes through three -way pipe I and connects flushing pipe subassembly and buffer solution feed liquor pipe, the middle -end of the inside of bottom entry to the overhead tank body of flushing pipe subassembly, the upper end on the inside right side of bottom entry to the overhead tank body of buffer solution feed liquor pipe, the lower extreme mouth of pipe of buffer solution feed liquor pipe are just to inboard jar of face of overhead tank body. The utility model discloses can effectively solve current pressure vessel single structure, be difficult for to wash and pr
