| description | The utility model discloses an anti-loosening device for a fastening bolt of a prefill valve of a large oil press. The anti-loosening device comprises an inner hexagon bolt, an anti-loosening connector, an anti-loosening connecting piece and a prefill valve flange. The inner hexagon bolt is assembled in a through hole of the prefill valve flange, the anti-loosening connector is assembled on the inner hexagon bolt and fixedly connected with the anti-loosening connecting piece, and the anti-loosening connecting piece is fixedly connected with the prefill valve flange. The problem that bolts of a prefill valve of an existing large oil press are loosened is solved, and it is guaranteed that the prefill valve works stably and reliably; and secondly, when the prefill valve needs to be disassembled and overhauled, the structure can be easily disassembled, and the valve body of the prefill valve cannot be influenced at all.
