Abstract
The utility model discloses a corrosion-resistant reinforced corrugated pipe compensator which comprises flanges, a corrugated pipe and a tetrafluoroethylene lining. The corrugated pipe is fixedly connected with the flanges at the two ends of the corrugated pipe to form a corrugated pipe compensation structure, the tetrafluoroethylene lining is attached to the inner surface of the corrugated pipe, an elastic negative pressure ring is arranged in a corrugated pipe inner wall ring groove, the negative pressure ring is a circular-ring-shaped component and is in small clearance fit with the tetrafluoroethylene lining in the corrugated pipe inner wall ring groove, and an outer reinforcing ring is arranged in a corrugated pipe outer wall ring groove. The corrosion-resistant reinforced corrugated pipe compensator can enable the tetrafluoroethylene lining not to deform under the action of negative pressure, and improve rigidity of the corrugated pipe significantly.
Description
Technical field
The utility model relates to a kind of pipe safety equipment, specifically, relates to a kind of lining tetrafluoro corrugated expansion joint.
Background technique
Lining tetrafluoro corrugated expansion joint, not only plays length, temperature, position and angle compensation effect, and has antisepsis in pipe-line system by at bellows inwall applying tetrafluoro liner.This lining tetrafluoro corrugated expansion joint in use exists certain defective: when being applied to the pipe-line system of negative pressure, the negative pressure in the pipeline may make the tetrafluoro liner produce distortion; On the other hand, bellows is thin-wall part, and is easily deformable, and no matter poor rigidity is internal pressure, or external pressure, all may make the bellows distortion, all normal uses of impact lining tetrafluoro corrugated expansion joint under the both of these case.
The model utility content
The utility model provides a kind of tetrafluoro liner that can make indeformable under suction function, the corrosion-resistant reinforced corrugated pipe compensator that bellows stiff is good for the deficiencies in the prior art.
The utility model 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, consists of the bellows collocation structure; Described tetrafluoro liner is fitted in bellows inside surface; Its improvements are: be provided with the elastic negative pressure ring in bellows inwall annular groove; Described negative pressure ring is circular member, and little Spielpassung between the tetrafluoro liner in the bellows inwall annular groove; Be provided with outer annular-stiffer in the described bellows outer wall annular groove.
The utility model further improves and is: described outer annular-stiffer is metal ring.
The utility model further improves and is: the ring that described negative pressure ring is surrounded by elastic metallic yarn, the tetrafluoro outer lining that is coated on the ring form.
The utility model further improves and is: described ring is surrounded by Spring Steel Wire.
The utility model compared with prior art has following good effect:
1, in bellows inwall annular groove, is provided with the elastic negative pressure ring, pushes down the tetrafluoro liner by the negative pressure ring, like this, even the 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 the elastic negative pressure ring, be provided with outer annular-stiffer in the bellows outer wall annular groove, significantly improved the rigidity of bellows.
3, the ring outer wall of negative pressure ring is coated with the tetrafluoro outer lining, has increased layer protective layer between negative pressure ring and tetrafluoro liner, the working life of significant prolongation lining tetrafluoro expansion joint.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the local enlarged diagram of I part among Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the 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, consists of the 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 the tetrafluoro liner 3 in the bellows 2 inwall annular grooves; Be provided with outer annular-stiffer 6 in the bellows 2 outer wall annular grooves, 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 that is coated on the 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.
