Flange structure convenient to install and using method thereof

Abstract

The invention relates to the technical field of pipeline connecting pieces, in particular to a flange structure convenient to install and a using method thereof. The flange structure convenient to install comprises a fixed flange and a connecting flange, lock head pieces which are symmetrically distributed are arranged on the fixed flange, convex lugs are arranged on the lock head pieces, a rotating wheel locking piece groove is formed in the connecting flange, a rotating wheel locking piece is arranged on the rotating wheel locking piece groove, the rotating wheel locking piece is provided with a lock head groove corresponding to the lock head piece, a convex lug supporting table is arranged in the lock head groove, the convex lug is connected with the convex lug supporting table in a clamped mode, the rotating wheel locking piece is provided with symmetrically-distributed extension arm rotating grooves, and extension arms are arranged in the extension arm rotating grooves. The extension arm is rotated clockwise to enable the rotating wheel locking piece to rotate, the convex lug supporting table and the convex lug are conveniently connected in a clamped mode, the purpose of rapid clamping is achieved, the position relation between a bolt and a nut does not need to be repeatedly corrected, a tool does not need to be used for fastening, the structure is simple, operation is convenient, and the installation efficiency is greatly improved.

Description

technical field [0001] The invention relates to a flange structure and a usage method thereof, in particular to an easy-to-install flange structure and a usage method thereof, and belongs to the technical field of pipeline connectors. Background technique [0002] Flange connection refers to the mechanical connection method in which several bolts are used to tighten and seal the gasket between flanges. It is often used for pipe sections that need to be disassembled frequently, such as steel pipes, cast iron pipes, and plastic pipes, as well as pipes with larger diameters. [0003] Flange connection can achieve a sealed connection under high pressure, so it is often used for the connection between pipes and pipe fittings. There are bolt holes on the flange, and the bolts make the two flanges tightly connected. Flange connection is an important connection method for pipeline construction. Flange connections are easy to use and can withstand high pressure. In industrial pipelin...

Problems solved by technology

[0004] The traditional flanges are fixed by bolts. Before fastening, the flanges should be placed first, and then the position of the flanges should be adjusted so that the bolt holes on the flanges correspond, and then the bolts should be passed through the flanges. The blue hole, and finally fixing the fastening nut on the flange, the operation is cumbersome and will waste a lot of time. Once the fastening is not in place, the flange will be tilted, so the sealing performance will be greatly reduced. Disassembly and reinstallation will greatly reduce the efficiency of installation

[0005] Chinese Invention Patent Publication No. CN 104006238 B discloses "a flange", which includes a fixed flange and a connecting flange. A fixing device is provided between the fixed flange and the connecting flange. There are several slide grooves in the axial direction, the fixing device includes claws arranged on the slide grooves, the claws are provided with snap-fitting parts for fixing the connection flange, and the fixed flange is also provided with drive clips A drive mechanism for the axial movement of the claw, the drive mechanism includes a circumferentially rotating drive wheel, the drive wheel is provided with a guide rail that is spirally wound around the central axis, and the claw is provided with a guide groove that matches the guide rail , easy to install and disassemble, the fixing device includes claws arranged on the chute, and the claws are provided with a clamping part for fixing the connecting flange. It will be more troublesome to turn the flange or rotate the fixed flange, not to mention that the rotation itself is difficult to achieve for larger flanges
