A flange connecting pipe is arranged on a flange plate, and the compression-resistant pipe whose pipe diameter is larger than that of a pipeline connecting pipe is arranged on the flange connecting pipe in a sleeved mode. One end of the compression-resistant pipe is in threaded connection with the pipe end of the connecting pipe of the female flange and the male flange, the other end of the compression-resistant pipe is in welded connection with the pipeline connecting pipe, and the connection of the flanges and the pipeline connecting pipe is made to be firmer. The coupled female flange and the male flange are adopted, sealing performance is good, and centering is easy to carry out in mounting. The reinforcing ribs are welded between the flange connecting pipe and the flange plate, the rigidity of the flange is enlarged, and serious buckling deformation is prevented from being generated due to insufficient rigidity of the flanges. Initial sealing is achieved through pre-tightening force of bolt connection, axial force generated by internal pressure is borne, and a detachable structure is convenient to use. The novel pipe connecting compression-resistant flange is reasonable in structure, easy to produce and manufacture, strong in compression resistance, large in rigidity, convenient to mount, easy to align and good in sealing performance, and is not prone to deformation.
Description
The utility model relates to a kind of pipeline coupling flange, and particularly a kind of pipeline connects resistance to compression flange, belongs to pipeline and connects design field.
Background technique
Flange is again flange plate or bead, flange be make pipe and pipe and and the interconnective part of valve, be connected in pipe end.Vital position is generally applied and played to flange in the field of the connection of pipeline.The general paired use of flange, a pair of flange, by the mounting hole of mutual correspondence is set, well connects pipeline through mounting hole by links such as bolts.The crushing resistance of flange is the important indicator of gauge flange quality, is also the assurance that guarantees the normal operation of pipeline simultaneously.But usually cause blue insufficient rigidity and produce excessive buckling deformation, in actual production, cause often bolt flange to connect the one of the main reasons of seal failure; Welding neckflange is not yielding, and good seal is widely used, and is applicable to pipeline that pressure or temperature fluctuate widely or the pipeline of high temperature, high pressure and low temperature, on the pipeline for delivery of expensive, inflammable, explosive medium yet.Under the impact of strong pressure, the life-span of a lot of flanges is all very of short duration, greatly about about 10-15.At present, for the research of flange compression resistance, its attention all, on the material and preparation process of flange, has but been ignored the design of its structure to the impact of compression resistance.Therefore, the intensity of flange, compression resistance exigence improve.
The utility model is exactly the deficiency that will overcome existing pipeline coupling flange, provides a kind of novel pipeline to connect resistance to compression flange.This flange arrangement is reasonable, manufactures easily, and compression resistance is strong, and rigidity is large, not yielding, and adjusting function is good, easy for installation, is easy to centering, stable operation, good seal performance.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of novel pipeline to connect resistance to compression flange, this flange is used in pairs, sealing surface form is male and fomale(M&F), while compressing installation, be easy to centering, and good seal performance, flanged pipe connects pipe end cover compression tube, for being threaded, be convenient to installation and removal, this novel pipeline adpting flange provides that one bears that pressure is large, sealing is strong, the convenient resistance to compression of dock accurately flange is installed.
In order to address the above problem, the utility model is realized by following technology,
A kind of novel pipeline connects resistance to compression flange, comprises compression tube, female flange, stiffening rib, bolt, spacer for bolt, flange gasket, nut and convex flange.On flange plate, be provided with flange connections, on flange connections, be equipped with the compression tube that pipe diameter is greater than connecting pipe of pipeline; Compression tube one end adopts and is threaded with male and female flange connecting tube pipe end, convenient disassembly, and the compression tube the other end and connecting pipe of pipeline are welded to connect, and make flange more fastening with being connected of connecting pipe of pipeline; The flange plate of male and female flange is provided with 6 bolts hole; Adopt paired male and female flange, good seal performance, is easy to centering when mounted; Stiffening rib is welded between flange connections and flange plate, strengthens rigidity of flange, avoids producing because rigidity of flange is not enough excessive buckling deformation; Bolt connects, and provides pretightening force to realize initial sealing, and bears the axial force that interior pressure produces, and removable structure is easy to use.
Flange connections end adopts and is threaded with compression tube, easy to use.
The compression tube the other end and connecting pipe of pipeline weld together, and compression resistance is strong.
Paired male and female flange design, is easy to centering when mounted, and good seal performance.
Stiffening rib is welded between flange connections and flange plate, and rigidity of flange is large, can not produce the distortion producing because of insufficient rigidity.
Adopted technique scheme, the beneficial effects of the utility model are:
The break traditions structural design of flange of the present invention, the design of stiffening rib, can effectively strengthen the anti-pressure ability of flange, the design of male and fomale(M&F), not only be conducive to increase the close property of flange, and workman's simple and efficient centering accurately of energy when installation exercise, thereby avoided installation process centering is brought to packing ring back and forth distortion or damage, effectively strengthened the efficiency of operation, and the employing of compression tube one end is threaded, convenient disassembly, one end adopts and is fixedly connected with, and compression resistance is strong.
Therefore, the utility model is connected resistance to compression flange with existing pipeline to be compared, and has outstanding advantage and is: the male and female flange that (1) is paired, and sealability is high, easy centering during installation; (2) it is more handy that the design of stiffening rib makes the application of flange on flanged pipe; (3) compression tube makes flange more fastening with being connected of pipeline, prevents that internal pipe pressure is excessive and causes flange and pipeline junction to occur crack equivalent risk.(4) simple in structure, easily manufactured, compression resistance is high.
A kind of novel pipeline that the utility model provides connects resistance to compression flange, has structurally realized adjustablely, and freely, compression resistance is strong in dismounting, and sealability is high, for practical application provides great convenience, can extensive use be connected with high pressure pipe line.
