Abstract
The utility model discloses a multi-edge blunt arc double oblique jet flow stabilizer. The stabilizer belongs to the new technical field of mechanical oil extraction. The stabilizer comprises a pumping rod coupling female joint, a multi-edge blunt arc double oblique jet flow stabilizer body sleeved on a pumping rod pup joint and a pumping rod coupling male joint, wherein the above-mentioned three parts are in series connection from up to down. The multi-edge blunt arc double oblique jet flow stabilizer body is a hollow cylinder whose two ends are abated or have arc transition. The cross section of the hollow cylinder is a multi-edge blunt arc. The multi-edge blunt arc body part of the hollow cylinder is vertically provided with a spiral flow channel or a vertical flow channel. The upper and the lower ends of the flow channels are three-dimensionally provided with double oblique jet flow holes that are vertically upward, vertically downward, horizontally left spiral or horizontally right spiral with an angle ranging from 1 to 45 degrees.
