PURPOSE:To provide a fluid conveying apparatus which is adapted to supply pressurized gas from between a discharge valve and a neck portion and flow the gas backward toward the neck portion of a tank in a fluid running to the discharge side so as to prevent formation of an arched lump at the neck portion. CONSTITUTION:Pressurized gas supplied from a pressurized gas supply pipe 6 flows backward as indicated with an arrow 7 toward a neck portion 4 in a transport pipe 5, and rises as indicated with an arrow 9 while mixing a fluid at the neck portion 4 to stand in the upper interior of a tank 1. The upper side wall of the tank 1 is provided with an exhaust tube 11 for previously exhausting the pressurized gas in the tank at the time of opening a cover, and air feed pipe 12 for bringing the cover 2 into contact with the inlet under pressure at the time of closing the cover, and a pressure gauge 13 which are coupled thereto. Thus, when the pressure of the pressurized gas becomes more than a fixed value, a fluid flows in the direction of an arrow 8 and passes through a discharging valve 10 to be exhausted. |
