Description
Technical field
The present invention relates to a kind of steel pipe is seamlessly connected mechanism and method.
Background technology
At present, steel pipe connects the connection such as multiplex flange, bolt and sealing gasket, wherein flange and steel pipe welding, both sides
Flange intermediate cryptographic packing, realizes the connection of steel pipe.This connected mode causes the presence of gap between steel pipe, with the steel of closing
During the conveying experiment of tubulation piping study particle, this gap can cause two kinds of unfavorable factors：1st, particulate matter is stored so that granules in pipe
Volumetric concentration is reduced, and experiment condition is not fixed, and affects experimental result；2nd, solid-liquid two-phase flows through this gap with certain speed, by
In unexpected difference in height, fluidised form gets muddled, and causes solid-liquid two-phase flow unstable, affects pipe resistance measurement etc..So, tradition
Connected mode can not meet requirement.
Content of the invention
In order to overcome above-mentioned deficiency, the present invention to provide a kind of steel pipe of new structure and be seamlessly connected mechanism and method, this
The technical scheme of invention is as follows：
A kind of steel pipe is seamlessly connected mechanism, for by the seamless connection of steel pipe one and steel pipe two, the mechanism include flange one,
Loose flange, flange two, O-ring, hold-down bolt and connecting bolt；
The end of the steel pipe one arranges one step of end setting that step one, the steel pipe two are connected with steel pipe one
Two, described two shoulder heights are identical, and junction causes two steps in same level, described two steps and flange one
Interior interporal lacuna coordinate so that the end of steel pipe one and steel pipe two is reached in the endoporus of flange one, and the left part of the flange one leads to
Cross welding manner to be fixed on steel pipe one, the right part of the flange one is at the step two of steel pipe two, the right side of the flange one
There is gap with step two in end；
The flange two is welded on the pipe shaft of steel pipe two, and the loose flange is arranged between flange one and flange two, described
Flange one, loose flange and flange two-way are crossed a connecting bolt and are fixed, in the corresponding opposite side of connecting bolt, one He of flange
Loose flange connects by hold-down bolt；
The loose flange arranges a chamfering at the endoporus of flange one, places O-ring at chamfering, and loose flange compresses O
Type circle is used for playing a part of sealing.
A kind of steel pipe seamless connecting method, using above-mentioned mechanism, its step is as follows：
（1）, first steel pipe one end process a step one, steel pipe two end process a step two, step one
Highly identical with step two, it is ensured that during connection, two steps are in same level；
（2）, steel pipe two weld a flange two on the pipe shaft at the step two, then at step two, be set with an activity
Flange, installs an O-ring at the endoporus of loose flange；
（3）, the two ends that steel pipe one and steel pipe two have step are inserted in flange one respectively, the left end of flange one props up step
One, steel pipe one is positioned by step one with flange one, and the right-hand member of flange one has space with step two, and the left end of flange one is by weldering
Connect mode and one fixation of steel pipe；
（4）, flange one, loose flange and flange two are fixed by a connecting bolt, corresponding another in connecting bolt
Flange one and loose flange are fixed by side with hold-down bolt.
The beneficial effect reached by the present invention：Mechanism can remove the gap of pipeline enclosure well so that the mistake of junction
Cross and be as good as with whole steel pipe, ensure that the flatness in pipe to greatest extent, be suitable for higher applications being required to pipeline.
