Particular fluid pumping device controlled by single-lever type cylinder and three-way ball valve

The utility model relates to the technical field of fluid conveying, in particular to a particular fluid pumping device controlled by a single-lever type cylinder and a three-way ball valve. The particular fluid pumping device comprises two tank bodies, an air jet pump and the three-way ball valve are arranged between the tank bodies, and a gate vale and the control cylinder are arranged at a feeding inlet and a discharging outlet respectively. Therefore, compressed air enters the tank bodies in an alternating mode, and switching of positive pressure and negative pressure is achieved. Continuous material discharging and material sucking operation is finished. According to the particular fluid pumping device, motion components are prevented from being in contact with materials, elements can not be abraded easily, maintenance cost is low, and a motor and other driving components are eliminated. Empty loading or overloading has no damage on the device, and any particular materials can be pumped.
