Description
Technical field
The present invention relates to a kind of expansion joint, more precisely, being a kind of double shielding anti-leak non-metal expansion joint.
Background technology
Expansion joint is traditionally also compensator, or telescopic joint.By constitute the bellows and end pipe of its operative body, support,
The annexes such as flange, conduit are constituted.Expansion joint is to compensate for the additional stress caused by temperature difference and mechanical oscillation, and is arranged on
A kind of flexible structure on container casing or pipeline.Using effective dilatation of its operative body bellows, with absorption line,
Conduit, container etc. are by the change in size reason such as expanding with heat and contract with cold and produce, or compensation pipes, conduit, container etc. is axial, laterally
And angular displacement.Noise-and-vibration-reduction is can also be used for, in heat supply, during in order to prevent that heat supply pipeline from heating up, because thermal stretching or temperature should
Power and cause pipe deforming or destruction, it is necessary to set compensator on pipeline, to compensate the thermal stretching of pipeline, so as to reduce tube wall
Stress and act on the active force on valve member or supporting structure.Expansion joint stretching repeatedly due to bellows in use
Corrugated pipe wall can be caused to rupture and then cause the leakage of expansion joint.
The content of the invention
The present invention mainly solves the technical problem present in prior art, so that it is non-to provide a kind of double shielding anti-leak
Type metal expansion joint.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of double shielding anti-leak non-metal expansion joint, comprising a bellows, one end of the bellows is provided with one first method
Orchid, the other end of the bellows is provided with a second flange, and the tube wall of the bellows is double-decker, comprising outer tube and interior
Pipe, the thickness of outer tube is 2-2.5 times of interior tube thickness, is connected between the outer tube and inner tube by the dowel of many equal lengths
Connect, closed inner space is formed between the outer tube and inner tube, lubricant is filled in the inner space, the outer tube is tied to be double-deck
Structure, includes basic unit and anticorrosive coat.
As preferred embodiments of the present invention, the length of described dowel is 2-5mm.
As preferred embodiments of the present invention, described basic unit and the thickness ratio of anticorrosive coat are 8：1.
Bellows is designed to double-decker by the double shielding anti-leak non-metal expansion joint of the present invention, respectively outer tube and
Inner tube, is connected between outer tube and inner tube by dowel, the inner space filling lubricant between outer tube and inner tube, is so on the one hand subtracted
Ripple tube wall ruptures caused by few bellows internal stress, on the other hand also plays double protection effect, prevent leakage.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the double shielding anti-leak non-metal expansion joint of the present invention；
Fig. 2 be Fig. 1 in bellows double-decker schematic diagram；
Fig. 3 be Fig. 2 in outer tube structural representation.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
As shown in Figure 1-Figure 3, a kind of double shielding anti-leak non-metal expansion joint 1, includes a bellows 10, the ripple
One end of pipe 10 is provided with a first flange 20, and the other end of the bellows 10 is provided with a second flange 30, the bellows 10
Tube wall be double-decker, comprising outer tube 101 and inner tube 102, the thickness of outer tube 101 is 2-2.5 times of the thickness of inner tube 102, institute
State between outer tube 101 and inner tube 102 and to be connected by the dowel 103 of many equal lengths, shape between the outer tube 101 and inner tube 102
Into closed inner space, lubricant is filled in the inner space, the outer tube 101 is double-decker, includes the He of basic unit 1011
Anticorrosive coat 1012.
It is 2-5mm as the length to further improvement of the present invention, described dowel 103.
As to further improvement of the present invention, described basic unit 1011 and the thickness ratio of anticorrosive coat 1012 are 8：1.
Bellows is designed to double-decker by the double shielding anti-leak non-metal expansion joint of the invention, respectively outer tube and
Inner tube, is connected between outer tube and inner tube by dowel, the inner space filling lubricant between outer tube and inner tube, is so on the one hand subtracted
Ripple tube wall ruptures caused by few bellows internal stress, on the other hand also plays double protection effect, prevent leakage.
Only illustrate the mentality of designing of the present invention in one embodiment above, in the case where system allows, the present invention can
To expand to external more functional modules simultaneously, so as to extend its function to greatest extent.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
