Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is schematic diagram at the A of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
The reinforced disposable directly buried compensation device of one as shown in Figure 1 and Figure 2, including left tube expansion 1 and the right tube expansion 2 of docking,
Left tube expansion 1 socket-connects with the big end of right tube expansion 2 and welds at socket place；The space formed after left tube expansion 1 is socketed with right tube expansion 2
Inside arranging corrugated tube 5, corrugated tube 5 two ends connect left tube expansion 1 by left adapter 3 respectively, connect right tube expansion 2 by right adapter 4；Left
Adapter 3 is taken root in the middle part of right tube expansion 2 at left tube expansion 1 respectively with right adapter 4, and welds with corrugated tube 5 end respectively after undergauge,
The internal diameter of undergauge rear left adapter 3 and right adapter 4 is equal to the central diameter of corrugated tube 5.Left tube expansion 1 is held greatly and is socketed on outside right tube expansion 2 holds greatly
Side, the socket place at left tube expansion 1 with right tube expansion 2 is set with reinforced pipe 6, and the big end of reinforced pipe 6 is socketed on outside left tube expansion 1, little
End is set in outside right tube expansion 2, and welds with left tube expansion 1 and right tube expansion 2 respectively.Uniformly have in the big end outer ring of reinforced pipe 6
The groove 7 of multiple strips, reinforced pipe 6 and left tube expansion 1 have been additionally provided with polytetrafluorethylecoatings coatings on the contact surface with right tube expansion 2
11、12.Reinforced pipe 6 and left tube expansion 1, right tube expansion 2 outer ring is corresponding is evenly arranged with multiple otic placode 9, pacifies between corresponding otic placode 9
Equipped with pull bar 8, pull bar 8 is fixed with each otic placode by nut.Each otic placode 9 side that left tube expansion 1 is arranged with right tube expansion 2 outer ring
It is respectively welded floor 10.
Left tube expansion 1, right tube expansion 2, left adapter 3, right adapter 4 and corrugated tube 5 form the one-off compensator of primitive form
In applying to that heating network is uncompensated and laying, it is adaptable to hot water preheating and wind preheat, and left adapter 3 and right adapter 4 are respectively left swollen
Pipe 1 is taken root in the middle part of right tube expansion 2, and welds with corrugated tube 5 end respectively after undergauge, undergauge rear left adapter 3 and right adapter 4
Internal diameter, equal to the central diameter of corrugated tube 5, can be prevented effectively from corrugated tube 5 and pipeline is produced extra blind flange force.Left tube expansion 1, right tube expansion 2
Internal groove can be processed in the end of welding, and after preheating, this secondary welding weld seam full weld, can effectively promote weld strength.
Reinforced pipe 6 and left tube expansion 1, right tube expansion 2 outer ring is corresponding is evenly arranged with multiple otic placode 9, between corresponding otic placode 9
Being provided with pull bar 8, pull bar 8 is fixed with each otic placode by nut.Each otic placode 9 one that left tube expansion 1 is arranged with right tube expansion 2 outer ring
Side is respectively welded floor 10, and the increase of above auxiliary body both can ensure that the stability in product transport process can also be held
By the blind flange force effect of pipeline self under cold conditions pressurized state, protect compensator.
Reinforced pipe 6 is tube expansion form global formation, and uniformly opens strip groove 7, reinforced pipe 6 in big opening end circumferencial direction
The effect crossing otic placode and pull bar can decrease frictional resistance at axially free adjusting position after fluting, big opening end is easier on a left side
The outer side shifting of tube expansion 1, reduces the difficulty of Field adjustment, and before preheating, reinforced pipe 6 is located adjacent to the otic placode side on right tube expansion 2, no
Hinder left tube expansion 1, the secondary welding of right tube expansion 2.After left tube expansion 1, right tube expansion 2 preheated weld complete, mobile reinforced pipe 6 to Fig. 2
Shown position is also welded with left tube expansion 1, right tube expansion 2, respectively simultaneously by groove 7 full weld of strip.Left tube expansion 1, right tube expansion 2 with add
Strong pipe 6 forms inside and outside double-deck booster action, provides double shield for one-off compensator stress relatively weak part.
Polytetrafluorethylecoatings coatings 11,12, is respectively interposed between reinforced pipe 6 and left tube expansion 1, right tube expansion 2, can effectively reduce it
Frictional resistance between, even if also can guarantee that under the simplest and the crudest operating environment that reinforced pipe 6 reinforced pipe is at left tube expansion
1, right tube expansion 2 is outer regulates flexibly, reduces execute-in-place difficulty of construction.
The above is only the preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
