To achieve the above object, the technical solution of the utility model：A kind of FlexbleJoint of resistance to positive/negative-pressure, including middle part
Rubber tube with bellows segment, the rubber tube bellows segment wave trough position are equipped with reinforcing ring, and the rubber pipe internal surface is equipped with lining
Fluorine layer is equipped with first flange, second flange in the rubber tube terminal mouthpiece cover, and the first flange and the second flange are same
Axis is arranged, and by adjusting screw rod relative positioning, the Fluorine-lined layer extends to the first flange, second flange outer end face, leads to
The length that screw rod adjusts bellows segment is overregulated, to adapt to use environment, while bellows segment can reduce vibration, environmental protection safety.
Further, the first flange, have in second flange multiple mutual corresponding journal stirrups, the adjusting screw rod fixed
On the first flange, the mutual corresponding journal stirrup of second flange, and on the via on the journal stirrup, on the outside of corresponding journal stirrup
Nut positioning, it is easy for assemble or unload, at the same convenient for adjust.
Further, the first flange, second flange are with respect to having buffering heavy platform, the buffering heavy platform and institute on flange face
It is corresponding to state bellows segment both ends, in mounting flange or when being adjusted, avoids bellows segment is caused to scratch or other damages, centainly
The external environment of bellows segment is protected in degree.
Further, the reinforcing ring is set as multiple, and is coaxially disposed with the first flange, second flange, adds
Strong ring carries out a certain range of reinforcement to bellows segment and consolidates, and while ensureing to improve resistance to positive/negative-pressure performance, consolidates compensator structure,
Prolong the service life the time limit.
The beneficial effects of the utility model：Compared with prior art, a kind of ripple compensation of resistance to positive/negative-pressure of the utility model
Device uses the rubber tube of middle part setting bellows segment, improves resistance to positive/negative-pressure performance, while adding reinforcing ring, rather than entirety makes
It is fixed with periphery, it improves elastic limit and ensure that tensile strength simultaneously, Fluorine-lined layer is set and is extended in outside, improves anti-corruption
Corrosion, reinforce air-tightness, guarantee do not become flat, gas leakage phenomena such as, protective conduit deform caused by the reasons such as pressure, temperature or break
It splits, while simplifying installation and maintenance process.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
1- first flanges in attached drawing；2- second flanges；3- rubber tubes；4- reinforcing rings；5- adjusting screw rods；6- Fluorine-lined layers；

Specific implementation mode
The utility model is further described with reference to specific embodiment and attached drawing.
As shown, the utility model includes the rubber tube 3 that middle part has bellows segment, bellows segment can be effectively reduced and be made an uproar
Sound, while rubber tube 3 is resisted using the good fabric disc type of intensity height, corrosion resistance with increasing elasticity, improving
The characteristic of tensile strength, 3 bellows segment wave trough position of the rubber tube are equipped with reinforcing ring 4, which sets according to the quantity of trough
It sets, and is coaxially disposed with rubber tube 3,4 outer surface of the reinforcing ring is equipped with erosion shield, consolidates 3 structure of the rubber tube, fortune
It is reliable to make process safety, reduces vibration, prolongs the service life, Fluorine-lined layer 6 is equipped in 3 inner surface of the rubber tube, in the rubber
3 both ends mouthpiece cover of sebific duct is equipped with first flange 1, second flange 2, and the first flange 1 is coaxially disposed with the second flange 2,
And by 5 relative positioning of adjusting screw rod, the Fluorine-lined layer 6 extends to the first flange 1,2 outer end face of second flange, passes through lining
The place of compensator and media contact is carried out insulation blocking by fluorine layer 6, is prevented from corroding, is influenced service life, and ensures that its is airtight
Property.
Specifically, having multiple mutual corresponding journal stirrups in the first flange 1, second flange 2, journal stirrup was equipped with
Hole, the adjusting screw rod 5 are located in the first flange 1, on 2 corresponding journal stirrup of second flange, and run through the via,
