Description
Technical field
The utility model belongs to technical field of pipeline connection, more particularly to a kind of flange three-piece.
Background technology
Flange (Flange), is called flange flange disk or bead.Flange is the part being connected with each other between axle and axle, is used for
Connection between pipe end；Also have with the flange imported and exported in equipment, for the connection between two equipment, such as reductor method
It is blue.Flange connects or bump joint, refers to be connected with each other as one group of combined sealing structure by flange, pad and bolt three
Releasable connection.Pipe flange, which is meant, matches somebody with somebody effective flange in plumbing installation, with the inlet and outlet flange that equipment is meant in equipment.Method
Perforation on orchid, bolt are close to two flanges.With pad sealing between flange.Flange point threaded connection (screwed connection) flange, weldering
Acting flange and clip flange.Flange all uses in pairs, and low pressure pipeline can use silk acting flange, four kilograms of pressure above
Use welded flange.Sealing gasket is added between two panels ring flange, is then fastened with bolt.The flange thickness of different pressures is different,
The bolt that they are used is also different.Water pump and valve, when being connected with pipeline, the part of these equipment facilities, also it is made relative
The flange shape answered, also referred to as flange connect.Every union piece closed simultaneously using bolt connection in two planar perimeters,
Typically referred to as " flange ", such as the connection of ventilation shaft, this kind of part is properly termed as " flange type part ".But this connection
The simply part of an equipment, such as the connection of flange and water pump, just it is bad water pump " flange type part ".It is more small-sized as
Valve etc., it can cry " flange type part ".
Flange connection is exactly two pipelines, pipe fitting or equipment, is first individually fixed on a ring flange, two ring flanges
Between, plus flange gasket, tightened together with bolt, complete connection.Some pipe fitting and equipment have carried ring flange, and
Belong to flange connection.Flange connection is the important connected mode of pipeline construction.Flange connection is easy to use, can bear larger
Pressure.In industrial pipeline, the use of flange connection is quite varied.Within the family, pipe diameter is small, and is low pressure, sees not
See that flange connects.If in a boiler room or production scene, the pipeline and equipment of flange connection everywhere.
It can be divided into according to connected mode flange connection species：Slip-on-welding plate flange, hubbed clip-on-welding flange, band neck are to welding method
Orchid, socket welding flange, screwed flange, blind flange, band neck welding neck collar loose flange, weldingon collar loose flange, ring groove flange and
Blind flange, major diameter flat flange, major diameter hubbed flange, spectactle blind, welding neck collar loose flange etc..
The engineer applied of rotary flange is very extensive.Rotary sealing mechanism rotation in correlation technique relies on carbon steel and carbon steel
Between frictional connection rotated, sealing structure seals using gas-flow closure circle, rotates during unaerated, close during inflation
Envelope.Using above-mentioned rotary sealing mechanism rotation, easily abrasion rotating mechanism material, sealing mechanism install relatively complicated, sealing ring
It is fragile.
Loose flange is flange plate that can be movable, is usually matched with water fittings (most common on telescopic joint),
Just respectively there is a piece of flange at telescopic joint both ends when producer dispatches from the factory, and are directly connected with the pipeline in engineering, equipment.The company of being commonly used for
Connect be material change.Loose flange is to utilize flange, steel loop etc. flange sleeve on pipe end, and flange can live on pipe end
It is dynamic.Steel loop or flange are exactly sealing surface, and the effect of flange is then that they are compressed.Loose flange is applied to the non-ferric such as steel, aluminium gold
In the connection and corrosion-resistant pipeline of category and stainless acid resistant steel container.It is commonly used on pipeline, at that rate, the bolt that comes loose can revolve
Turn the pipeline on both sides, then tighten.Loose flange is also referred to as lap joint flange.
Utility model content
The utility model provides a kind of simple in construction, side of installing and using to solve technical problem present in known technology
Just a kind of flange three-piece of operating efficiency, is improved.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：A kind of flange three
Part set, including main flange, rotary flange, locating flange and loose flange, the main flange are fixedly connected with pipeline I,
The locating flange is fixedly connected with main flange, and the loose flange is fixedly connected with main flange, the rotary flange with
Main flange is slidably connected, and the rotary flange is slidably connected with pipeline II, and the pipeline II is slidably connected with loose flange.
Further, annular groove is provided with the locating flange excircle, for coordinating with extraneous flanged structure, for positioning,
And pad is installed between locating flange and main flange, pipeline location can be adjusted by exchanging spacer thickness.
Further, the running track of cylindrical roller is provided with the rotary flange.
Further, one group of cylindrical roller is placed between the rotary flange and pipeline II.
The utility model has the advantages and positive effects of：The utility model realizes the connection and positioning to pipeline,
A kind of new method is provided for the connection of pipeline；Cylindrical roller between rotary flange and pipeline II substantially reduces pipeline II
Resistance when being rotated relative to pipeline I, greatly improve the resistant to damage ability of flange coupling part；Protective case is protected to a certain extent
It is free from the influence of the external environment coupling part has been protected；The annular groove of locating flange, the pad between locating flange and main flange are real
Pipeline location can be adjusted from more perspective by having showed, and then more accurately be positioned.
