Abstract
The invention discloses a corrosion-resistance reinforced corrugated-pipe compensator which comprises flanges, a corrugated pipe and a Teflon liner. The corrugated pipe is fixedly connected with the flanges at two ends to form a corrugated-pipe compensation structure. The Teflon liner is attached to the inner surface of the corrugated pipe. Elastic negative-pressure rings are arranged in ring slots of the inner wall of the corrugated pipe. The negative-pressure rings are circular ring parts and are in small clearance fit with the Teflon liner in the ring slots of the inner wall of the corrugated pipe. Outer reinforcing rings are arranged in ring slots of the outer wall of the corrugated pipe. By the arrangement, the Teflon liner is free of deformation under the action of negative pressure, and rigidity of the corrugated pipe can be obviously improved.
Description
Technical field
The present invention relates to a kind of pipe safety equipment, specifically, relate to a kind of lining tetrafluoro corrugated expansion joint.
Background technique
Lining tetrafluoro corrugated expansion joint, by bellows inwall laminating tetrafluoro liner, in pipe-line system, not only plays length, temperature, position and angle compensation effect, and has antisepsis.This lining tetrafluoro corrugated expansion joint in use exists certain defect: when being applied to the pipe-line system of negative pressure, the negative pressure in pipeline may make tetrafluoro liner produce distortion; On the other hand, bellows is thin-wall part, easily deformable, and no matter poor rigidity is internal pressure, or external pressure, all may make bellows distortion, all normal uses of impact lining tetrafluoro corrugated expansion joint under both of these case.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of tetrafluoro liner that can make indeformable under suction function, the corrosion-resistant reinforced corrugated pipe compensator that bellows stiff is good.
The present invention is achieved through the following technical solutions technical goal.
Corrosion-resistant reinforced corrugated pipe compensator, comprises flange, bellows, tetrafluoro liner; Described bellows is fixedly connected with the flange at two ends, forms bellows collocation structure; Described tetrafluoro liner is fitted in bellows inside surface; Its improvements are: in bellows inwall annular groove, be provided with elastic negative pressure ring; Described negative pressure ring is circular member, and little Spielpassung between tetrafluoro liner in bellows inwall annular groove; In described bellows outer wall annular groove, be provided with outer annular-stiffer.
The present invention further improves and is: described outer annular-stiffer is metal ring.
Further improvement of the present invention is: the ring that described negative pressure ring is surrounded by elastic metallic yarn, the tetrafluoro outer lining being coated on ring form.
Further improvement of the present invention is: described ring is surrounded by Spring Steel Wire.
The present invention compared with prior art, has following good effect:
1, in bellows inwall annular groove, be provided with elastic negative pressure ring, by negative pressure ring, push down tetrafluoro liner, like this, even tetrafluoro liner can not be out of shape under suction function, thereby guaranteed the normal use of lining tetrafluoro expansion joint yet.
2, in bellows inwall annular groove, be provided with elastic negative pressure ring, in bellows outer wall annular groove, be provided with outer annular-stiffer, significantly improved the rigidity of bellows.
3, the ring outer wall of negative pressure ring is coated with tetrafluoro outer lining, between negative pressure ring and tetrafluoro liner, has increased layer protective layer, the working life of significant prolongation lining tetrafluoro expansion joint.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the local enlarged diagram of I part in Fig. 1.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
Corrosion-resistant reinforced corrugated pipe compensator shown in the drawings, comprises flange 1, bellows 2, tetrafluoro liner 3; Bellows 2 is fixedly connected with the flange 1 at two ends, forms bellows collocation structure; Tetrafluoro liner 3 is fitted in bellows 2 internal surfaces; In bellows 2 inwall annular grooves, be provided with elastic negative pressure ring 4; Negative pressure ring 4 is circular member, and little Spielpassung between tetrafluoro liner 3 in bellows 2 inwall annular grooves; In bellows 2 outer wall annular grooves, be provided with outer annular-stiffer 6, in the present embodiment, outer annular-stiffer 6 is metal ring.
In the present embodiment, the ring 4.2 that negative pressure ring 4 is surrounded by elastic metallic yarn, the tetrafluoro outer lining 4.1 being coated on ring 4.2 form, like this working life of significant prolongation lining tetrafluoro expansion joint.
In the present embodiment, ring 4.2 is surrounded by Spring Steel Wire.
