Description
Technical Field
The utility model belongs to the technical field of the pipe-line installation part, specificly be a novel corner flange.
Background
Flanges are parts of the interconnection between shafts for the connection between pipe ends. The flange connection is that two pipelines, pipe fittings or equipment are respectively fixed on a flange plate, a flange pad is arranged between the two flange plates and is fastened together by bolts, and the flange and the bolts are mutually connected to form a detachable connection of a group of combined sealing structures. The flange connection is an important connection mode for pipeline construction. The flange connection is convenient to use and can bear larger pressure. The flange is divided into a threaded connection (screw thread connection) flange, a welding flange and a clamping flange. The flanges are used in pairs, holes are formed in the flanges, a sealing gasket is arranged between the two flange plates, and then the flanges are fastened through bolts. However, when the flanges are used, the holes of the two flanges are not aligned, the bolts cannot be inserted into the holes for connection, the pipelines need to be rotated to align the holes, and the problems of complex installation and great operation difficulty exist. Therefore, a flange which can be quickly and conveniently installed is urgently needed to solve the problems.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a novel corner flange. Therefore, the problems that the existing flange mounting holes are not aligned, the bolts cannot be inserted and connected inconveniently, and the operation difficulty is high are solved.
The utility model provides a novel corner flange contains upper flange, lower flange, bolt, upper flange evenly distributed punchhole, the lower flange on evenly distributed arc punchhole, arc punchhole bolt can pass the fixed upper flange of punchhole when the lower flange rotates, bolt aperture and flange punchhole phase-match.
Preferably, the flange can be connected with a fixing piece through a screw, and the fixing piece is provided with a protruding part.
Preferably, the upper flange comprises a fastener, the fastener is connected with the upper flange in a suitable connection mode, and the fastener is provided with internal threads matched with the protruding part screw of the fixing piece.
Preferably, the upper flange comprises a fastener, and the fastener is connected with the upper flange in a welding mode.
Preferably, the aperture between the two arcs of the lower flange arc-shaped eyelet is the same as that of the upper flange eyelet, and the eyelets of the upper flange can all fall in the corresponding range of the arc-shaped eyelet.
The flange can be externally buckled with a decorative cover to cover the flange, and the lower flange which is more attractive and preferable can be connected by pipe welding.
The utility model provides a pair of novel corner flange is because the big flange aperture that goes up of arc punchhole's radian scope can all fall on in the arc punchhole, does not need rotatory flange adjustment hole position, and flange mounting easy operation has avoided the unable condition of installing of bolt that aligns of upper and lower flange punchhole, adopts the corner flange to dismantle conveniently, and the flange covers the connecting piece behind the installation dress trim cover, and is more pleasing to the eye.
