Mud ramming flow hydraulic control loop

The utility model discloses a mud ramming flow hydraulic control loop, and relates to the technical field of blast furnace metallurgical equipment, the mud ramming flow hydraulic control loop comprises a first control loop for controlling a mud ramming mechanism of a hydraulic mud gun, the first control loop forms an oil inlet loop and an oil return loop under the condition of performing mud gun hole plugging and mud ramming actions, and a turbine flowmeter is mounted on the oil return loop; the mud ramming flow hydraulic control loop is further provided with a flow totalizer located in the electrical control cabinet, the flow totalizer is in signal connection with the turbine flowmeter, and the actual mud ramming amount is calculated through the flow totalizer. The defects that when a mechanical pointer indicating device is adopted in a hydraulic mud gun mud ramming amount indicating device, the accuracy is poor, the mud ramming amount is judged according to the experience of a furnace worker, the iron notch
