Description
Technical field
The present invention relates to a kind of flange arrangement more particularly to a kind of easy centering resistance to compression W.N flanges, belong to pressure pipeline company
Connect design field.
Background technique
In machinery field, flange is a kind of attachment device being widely used, and plays in pipeline and pressure vessel field
Vital effect；Flange just will affect whole system, or even will cause very big personal injury once damaging；Flange
Crushing resistance is the important indicator of gauge flange quality, while being also the condition for guaranteeing pipeline and operating normally.Especially in pressure vessel
Connect with pipeline and pressure pipeline between connection to the more demanding of flange, not only improve and want on material and preparation process
It asks, the requirement to structure design also increasingly increases.Flange is generally employed in pairs, by the way that corresponding mounting hole, two methods are arranged
Mounting hole is passed through using connectors such as bolts and is connected to pipeline as airtight and watertight padding by seal washer when the sealing face contact of orchid
Together.In some relatively large flanges, the demand of bolt also increases therewith, not only causes the burden in cost, also unfavorable
In the lightweight of equipment.Currently, the ring flange applied in domestic production, which is symmetrically installed, has error or dislocation, lead to sealing effect
It is bad, often overflow material from junction, especially for there are significant shock or transport greater impact fluids
Pipeline, leakage is even more and happens occasionally at flange sealing surface.
The present invention seeks to overcome the shortcomings of existing flange arrangement, provides a kind of easy centering pressure-proof flange, which connects strong
Degree is high, sealing effect is good, easy for assemble or unload, be easy to centering, and structure is simple, easily manufactured, and has good compressive property,
It is adapted for mount on significant shock or transports the pipeline of greater impact fluid.
Summary of the invention
The technical problem to be solved by the present invention is the present invention provides a kind of easy centering pressure-proof flange structure, the invention with
Pipeline connection uses butt welding pattern, and the linkage section between ring flange and pipeline uses conical shell structure.Flange uses in pairs, ring flange
End face is used for centering centering using concave-convex ellipsoidal structure, and intersects uniformly distributed bolt hole, adopts and is bolted connection, not only guarantees
Absolute tightness, also reduces the usage amount of bolt；The design of conical shell linkage section, when for transport greater impact fluid,
Certain buffer function is played, the resistance to compression and shock resistance of flange are improved.
To solve the above-mentioned problems, the present invention is achieved through technology:
A kind of easy centering pressure-proof flange, including ellipse around boss, ring flange, reinforcing rib, bolt hole and conical shell；Oval convex
Platform (groove) is evenly arranged on flange surface；Uniformly distributed bolt hole reduces spiral shell with ellipse around boss (groove) arranged for interval on ring flange
Bolt usage amount and reach light-weighted purpose under the premise of not influencing flange compressive property；Reinforcing rib is welded on conical shell and flange
Between disk, for improving rigidity of flange, flange is avoided to lead to excessive buckling deformation because of insufficient rigidity；Conical shell linkage section is to favourable opposition
Hitting property fluid has certain buffering effect, further improves the compressive property of flange.
Bonding pad between ring flange and pipeline uses conical shell structure, and conical shell small end has a bit of interface connecting with pipeline
Pipe；
Flange surface is evenly distributed with ellipse around boss (groove), and with bolt hole arranged for interval, be easy to centering and good seal performance；
The high 5-25mm of ellipse around boss, corresponding flange oval-shaped groove depth is also 5-25mm；
When flange acts in pairs, Gask-O-Seal is equipped between flange male and fomale(M&F) and bolt hole；
Reinforcing rib is welded between conical shell and ring flange, improves the rigidity of ring flange.
Using above-mentioned technical proposal, the beneficial effects of the present invention are:
The present invention breaks the structure design of conventional flange, using oval male and fomale(M&F) and the spaced apart design mode of bolt hole
Formula is easy to quick accurate centering, effectively enhances the efficiency of operation, reached lightweight while guaranteeing sealing performance
Purpose；The use of conical shell segment structure is applied the present invention preferably on the big fluid line of transport shocks, is played certain
Buffer function increases the compressive property of flange；The appropriate connection of reinforcing rib, increases the rigidity of flange, avoids because bearing
Biggish pressure leads to problems such as ring flange deform.
Therefore, the present invention is compared with existing flange, and have the advantages that prominent be: (1) ellipse is concave-convex on flange surface
The design in face when so that companion flange cooperating, is easy to centering and increases the sealing performance of flange；(2) oval male and fomale(M&F) and spiral shell
Keyhole arranged for interval, so that application of the flange on flange pipe is more handy, and in the effect of resist compression that ensure that flange
While decrease bolt usage amount, fully demonstrated the lightweight of flange design；(3) it is adopted between ring flange and connected adapter tube
With cone section connection, the fluid big to impact plays certain buffer function；(4) design of reinforcing rib, so that ring flange is rigid
Degree increases, and avoids buckling deformation.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of easy centering pressure-proof flange provided by the present invention；
Attached drawing 2 is the top view of attached drawing 1.
In attached drawing 1: 1, ellipse around boss；2, ring flange；3, reinforcing rib；4, bolt hole；5, conical shell
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.As shown in the picture, it is anti-that the present invention provides a kind of easy centerings
Pressure flange, 5 big end of conical shell and ring flange weld, and small end is that straight section and connected pipe use butt welding linked vector graph；Ring flange 2
The uniformly distributed oval boss 1 in end, the flange end occurred in pairs with it open oval recess；2 end of ring flange is evenly distributed with bolt hole 4, and
Bolt hole 4 and ellipse around boss (groove) 1 arranged for interval, arrangement quantity can be made by oneself according to pipeline pressure；Reinforcing rib 3 is welded to connect
Between conical shell 5 and ring flange 2, the effective rigidity for improving ring flange.When flange acts in pairs, flange male and fomale(M&F) and bolt hole
Between will be equipped with Gask-O-Seal, and with bolt fastening engaged therewith connection.Sealing effect is good, and compressive property is strong.
Finally, it should be noted that above embodiments, which are only to illustrate this explanation, not limits technical side described in the invention
Case；Therefore, although this specification is referring to the above embodiments, the present invention has been described in detail, this field
It is to be appreciated by one skilled in the art that still can modify or equivalently replace the present invention；And all do not depart from the present invention
Spirit and scope technical solution and its improvement, be intended to be within the scope of the claims of the invention.
