Connect, be socketed in outer on the left of second guide pipe on the right side of first guide pipe, the expansion joint body fits are described the
On the outside of one guide pipe and the second guide pipe, the two ends of the expansion joint body are fixedly connected with left plate and right plate respectively, institute
State and the first sealing gasket is provided with the inside of the first guide pipe right-hand member, the second sealing gasket is provided with the outside of the second guide pipe left end.
Preferably, filled with insulation in space between the expansion joint body and the first guide pipe, the second guide pipe
Filler.
Preferably, be fixed on the outside of first sealing gasket on first guide pipe, first sealing gasket it is interior
It is close to the outside of second guide pipe and can be slided with respect to the second guide pipe in side.
Preferably, being fixed on the inside of second sealing gasket on second guide pipe, outside second sealing gasket
It is close to the inner side of first guide pipe and can be slided with respect to the first guide pipe in side.
Preferably, the inwall of first guide pipe and the second guide pipe is equipped with corrosion-inhibiting coating.
Preferably, first sealing gasket and the second sealing gasket are made by rubber.
Preferably, the insulation filler is refractory fibre or rock wool particle.
The beneficial effects of the invention are as follows：
The present invention is provided with the first guide pipe and the second guide pipe being mutually socketed in the inner side of expansion joint, the first guide pipe and the
Two guide pipes can not only play a supporting role, and prevent the excessive deformation of expansion joint, lead between the first guide pipe and the second guide pipe
Cross the first sealing gasket and the second sealing gasket is sealed, effectively block fluid directly washing away to expansion joint body, prevent
Expansion joint body is worn and corroded, and the first sealing gasket and the second sealing gasket have not only acted as the effect of dual-seal, moreover it is possible to rise
To the position-limiting action for preventing that the first guide pipe and the second guide pipe from departing from.The present invention also expansion joint body and the first guide pipe,
Insulation filler is provided with space between second guide pipe, influence of the fluid temperature variations to expansion joint can be effectively reduced,
Avoid expansion joint expanding with heat and contract with cold and being easily damaged excessively.The present invention is simple in construction, reasonable in design, can effectively extend expansion
The service life of section.

Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description：
As shown in figure 1, a kind of bellows expansion joint, including left plate 2, right plate 3, the first guide pipe 4, the and of the second guide pipe 5
Expansion joint body 1, the left end of the first guide pipe 4 is fixedly connected with left plate 2, and right-hand member and the right plate 3 of the second guide pipe 5 are consolidated
Fixed connection, left plate 2 and right plate 3 are connected with pipeline 9 respectively, and the right side of the first guide pipe 4 is socketed in the left side of the second guide pipe 5
Outside, expansion joint body 1 is sleeved on the first guide pipe 4 and the outside of the second guide pipe 5, the two ends of expansion joint body 1 respectively with left side
Plate 2 is fixedly connected with right plate 3, is provided with the outside of the first sealing gasket 6, the left end of the second guide pipe 5 and is set on the inside of the right-hand member of the first guide pipe 4
