Description

Technical Field

[0001] The utility model relates to the technical field of maintenance tools, in particular to a semi-ball valve driving and disassembling tool. Background Art

[0002] The semi-ball valve is a special valve, which is characterized by the size offset between the center axis of the valve body and the center axis of the semi-ball, and the sealing pair is only set on one side of the valve body. It achieves the effect of opening and closing by rotating the ball around the center line of the valve body. The opening and closing part of the semi-ball valve is a sphere with a hole, and the sphere rotates with the valve stem to realize the opening and closing action. In the pipeline, the semi-ball valve is mainly used to cut off, distribute and change the flow direction of the medium. Due to its special structure, the semi-ball valve has many advantages, such as no friction when switching, the seal is not easy to wear, the opening and closing torque is small, the flow resistance is small, the sealing is reliable, the performance is stable, and the service life is long. Disassembling the drive head is an important part of the daily maintenance of the semi-ball valve. The current method of disassembling the drive head is to remove the fixing bolts of the drive head and then use a sledgehammer to hit the drive head to make the drive head separate from the semi-ball valve.

[0003] A Chinese utility model patent with the authorization publication number CN219275038 discloses a semi-ball valve drive disassembly tool, which includes a base, a lifting piece and a semi-ball valve. A mounting groove is provided on the base for fixing and supporting the lifting piece and the semi-ball valve. A driving head is installed on the valve stem of the semi-ball valve. The driving head is designed so that its radius is larger than the diameter of the notch on the front side groove wall of the mounting groove, so it cannot directly pass through the notch. The lifting piece is composed of a cylinder body and a piston, and the piston can slide in the cylinder body. During the disassembly process, the cylinder body and the piston are placed in the mounting groove, and the tail end of the cylinder body is close to the rear side groove wall of the mounting groove. The head end of the piston is inserted into the driving head and abuts against the valve stem. When the driving head needs to be disassembled, by operating the lifting piece, the piston will move in the cylinder body and apply uniform pressure to the driving head. Therefore, the existing technology cannot adapt to lifting pieces and semi-ball valves of different sizes, and each tool can only correspond to a workpiece of a smaller range of sizes.
