| description | The utility model provides a change valve formula pressure pulse generator in pit connects gradually the tube structure that constitutes by top connection, urceolus, lower clutch, and inside formationof tube structure overflows the passageway, its characterized in that, still including the commentaries on classics valve, it installs inside the tube structure to change the valve, it includes stator, rotor, main shaft to change the valve, the discharge orifice was offered to the stator, the rotor is fixed on the main shaft, and to change flow surface long -pending around the discharge orifice of crossing of main shaft rotation on to the stator for the rotor the sheath offset is installed at the tube structure inner wall. The inside actuating mechanism that still is provided with of tube structure, the main shaft that changes the valve is connected to the actuating mechanism power take off end. The rotor passes through main shaft and retarder connection, actuating mechanism is includingthe reduction gear, magnet |
