Zusammenfassung: | The utility model belongs to the field of oil pumping equipment and devices, and particularly relates to an angle-type check valve magnetic ball taking device which comprises a connecting sleeve. A magnet is connected with one end of the interior of the connecting sleeve, an operation rod is connected with the other end of the interior of the connecting sleeve, a through hole is axially formed in the magnet, the front end of the through hole is provided with a horn-shaped through hole, and the rear end of the through hole is provided with a cylindrical through hole. The angle-type check valve magnetic ball taking device is simple in structure, easy to manufacture and low in cost; the front end of the magnet is provided with an inward concave arc horn-shaped through hole, so that the contact area of the magnet and a valve ball is increased, and the valve ball can be firmly attracted; crude oil remaining in an angle-type check valve can enter a bush through the through hole in the magnet, the crude oil is preve |
