Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve processing, in particular to a butterfly valve processing tool. Background Art

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on-off control of low-pressure pipeline media. A butterfly valve has a disc as the closing member, which rotates around the valve axis to open and close. The valve can be used to control various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. It is widely used, and during its processing and production process, the components need to be assembled and docked.

[0003] Existing butterfly valves have the following disadvantages during assembly and processing: During assembly and processing, multiple components such as the internal valve stem, seals, valve plates, etc. need to be installed inside the butterfly valve housing structure, and the butterfly valve is generally a structure with connecting flanges on both sides. When the outer diameter of the connecting flange is larger than the valve body structure, the butterfly valve cannot be stably positioned, affecting the installation efficiency of the internal components. For this reason, we propose a butterfly valve processing tooling. Utility Model Content

During use, the adjustment slide can be driven to move inside the fixing seat by screwing the screw, thereby adjusting the position of the clamping seat.

[0008] Furthermore, a lower shaft seat slot is provided inside the platform between the arc grooves, and a clamping groove is provided on the opposite side of the clamping seat surface; the stability of the butterfly valve assembly when fixed can be further improved through the lower shaft seat slot and the clamping groove structure.

[0009] Furthermore, the interior of the fixing seat is movably connected to a slide, and the inclined rod is installed on the top of the slide; the slide structure facilitates horizontal adjustment of the positions of the inclined rod and the clamping seat.

[0010] Furthermore, a rotating ring located inside the slide is installed at one end of the screw rod close to the slide rod; when the screw rod is turned, the rotating ring structure can prevent the slide rod from rotating while not affecting its horizontal movement.
