Fig. 1 is an assembly schematic of a quick opening and closing tool for a welded ball valve of the present invention.

Wherein: 1-torque wrench, 2-speed reducer, 3-four-claw sleeve head, 4-fixed handle.

Detailed Description

The utility model is described in detail below with reference to the accompanying figure 1 and the specific embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to the picture, a quick opening and closing tool for welding a ball valve comprises a torque wrench 1, a speed reducer 2 and a four-claw sleeve head 3. Four-jaw pullover 3 is sleeve structure, and inside is provided with square or cylindrical through-hole, square through-hole contains square head hole and square tail hole, cylindrical through-hole contains cylindrical head hole and cylindrical tail hole, and this four-jaw pullover cooperatees with the valve. The head of the speed reducer 2 is connected with the tail of the torque wrench 1, and the other end of the speed reducer 2 is of a cylindrical or square tenon structure and is connected with a cylindrical or square head hole of the four-claw sleeve head 3 by a positioning pin. The speed reducer 3 can reduce the rotating speed and obtain larger torque to finish the work.
