Brief description
Fig. 1 is this utility model structural representation;
Fig. 2 is schematic diagram at the A of Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.
The reinforced disposable directly buried compensation device of one kind 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 is socket-connected and in socket place welding with the big end of right tube expansion 2;The space being formed after left tube expansion 1 with right tube expansion 2 socket
Interior setting corrugated tube 5, corrugated tube 5 two ends are passed through left adapter 3 respectively and are connected left tube expansion 1, connect right tube expansion 2 by right adapter 4;Left
Adapter 3 and right adapter 4 are taken root respectively in the middle part of left tube expansion 1 with right tube expansion 2, and weld 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 hold greatly be socketed on right tube expansion 2 hold greatly outer
Side, is set with reinforced pipe 6 in the socket place of left tube expansion 1 and right tube expansion 2, 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 placodes 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
It is adaptable to hot water preheating and wind preheating in applying to that heating network is uncompensated and laying, left adapter 3 and right adapter 4 are respectively left swollen
