Abstract
The invention discloses a welding neck flange handhole. The welding neck flange handhole comprises a connecting base. Two fixing buckles are arranged on the outer wall of the connecting base and are symmetrically arranged. The opposite inner side faces of the fixing buckles are each provided with an occlusion groove. The connecting base is connected with a welding neck flange. A flange plate is arranged on the welding neck flange. An inner hole is formed in the center of the flange plate and communicates with the interior of the connecting base. Multiple screw holes are formed in the flange plate. The screw holes are distributed with the center of circle of the inner hole as the center in a central symmetry manner. Multiple sealing ring positioning grooves are formed in the flange plate and are distributed in a concentric circle manner, and the center of the circle is located on a center axis of the inner hole. According to the welding neck flange handhole, the connecting base is arranged on a body, the two fixing buckles are arranged on the connecting base, the connecting base can be flexibly fixed to equipment through the fixing buckles, both assembly and disassembly are convenient, cut of metal is avoided, the use efficiency is higher, and use is more convenient and faster.
