Description

Technical Field

[0001] The present application relates to the technical field of flange nut tightening wrenches, and in particular to a flange nut tightening wrench for a torque wrench. Background Art

[0002] A torque wrench, also known as a torque wrench or an adjustable torque wrench, is a type of wrench. According to the power source, it can be divided into: electric torque wrench, pneumatic torque wrench, hydraulic torque wrench and manual torque wrench. Manual torque wrench can be divided into: preset type, fixed value type, dial type, digital display type, slip type, bending type, and kilogram wrench. When the tightness of screws and bolts is critical, the use of a torque wrench allows the operator to apply a specific torque value.

[0003] A flange nut is a nut that has a wide flange on one end that acts as an integrated washer. This serves to distribute the pressure of the nut across the component being secured, thereby reducing the possibility of component damage and making it less likely to loosen due to the uneven fastening surface. These nuts are mostly hexagonal in shape and made from hardened steel, usually with a zinc coating.

[0004] The discharge flanges at both ends of the fracturing pump are generally fastened with stud bolts. Since the bolts and nuts are relatively close to the flange neck, conventional open-end wrenches, plum wrenches and sockets cannot be inserted, and the rotation angle is relatively small, making installation very inconvenient or impossible to tighten in place.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
