Abstract
The invention discloses a negative-pressure resistant reinforced metal hose which comprises a corrugated pipe, a net body and a Teflon lining. The corrugated pipe forms the main body of the reinforced metal hose, the net body wraps the outer wall of the corrugated pipe, and the Teflon lining is fitted to the inner surface of the corrugated pipe. Elastic reinforced ribs are arranged in ring slots of the corrugated pipe. The elastic reinforced ribs are circular ring parts and are in clearance fit with the Teflon lining in the ring slots of the corrugated pipe. Further improvement lies in that the reinforced ribs are composed of annular rings enclosed by titanium wires, or annular rings enclosed by elastic metal wires and an outer Teflon lining wrapping the annular rings. The Teflon lining is free of deformation even under the action of negative pressure since the Teflon lining is pressed by the reinforced ribs, and normal use of the lined Teflon metal hose is thereby guaranteed; meanwhile, strength of the metal hose is increased by the aid of the reinforced ribs, and service life of the metal hose is remarkably prolonged.
Description
Technical field
The present invention relates to a kind of metallic hose, specifically, the present invention relates to a kind of corrugated flexible metal tube.
Background technique
The main body of corrugated flexible metal tube is bellows, for protection bellows, generally on its outer wall, is set with dictyosome, needs corrosion-resistant use occasion for some, at bellows inside surface laminating tetrafluoro liner.The corrugated flexible metal tube of this structure can play and flexibly connect preferably effect, its antiseptic property is also better, but the corrugated flexible metal tube of this structure exists certain defect: in the time being applied to the pipe-line system of negative pressure, negative pressure in pipeline may make tetrafluoro liner produce distortion, thus the normal use of impact lining tetrafluoro corrugated flexible metal tube.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, even if a kind of reinforced metal of resistance to negative pressure flexible pipe that can make tetrafluoro liner also can not be out of shape is provided under suction function.
The present invention is achieved through the following technical solutions technical goal.
The reinforced metal of resistance to negative pressure flexible pipe, it comprise form its main body bellows, be sleeved on bellows outer wall dictyosome, be fitted in the tetrafluoro liner of bellows inside surface; Its improvements are: in bellows annular groove, be provided with elasticity and strengthen muscle; Described enhancing muscle is circular member, and Spielpassung between tetrafluoro liner in bellows annular groove.
The present invention further improves and is: described enhancing muscle is the ring that titanium silk surrounds.
The present invention is another kind of further to be improved and is: the ring that described enhancing muscle is surrounded by elastic metallic yarn, the tetrafluoro outer lining being coated on ring form.
The present invention compared with prior art, has following good effect:
1, in bellows annular groove, be provided with elasticity and strengthen muscle, push down tetrafluoro liner by strengthening muscle, like this, even tetrafluoro liner also can not be out of shape under suction function, thereby ensured the normal use of lining tetrafluoro metallic hose, increase muscle has also increased the intensity of metallic hose simultaneously.
2, strengthening muscle is the ring that titanium silk surrounds, and the antiseptic property of titanium silk is better, makes to strengthen muscle and also has good antiseptic property.
3, the ring outer wall of enhancing muscle is coated with tetrafluoro outer lining, between enhancing muscle and tetrafluoro liner, has increased layer protective layer, the working life of significant prolongation lining tetrafluoro expansion joint.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the local enlarged diagram of the 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.
The reinforced metal of resistance to negative pressure flexible pipe shown in the drawings, it comprise form its main body bellows 1, be sleeved on bellows 1 outer wall dictyosome 2, be fitted in the tetrafluoro liner 3 of bellows 1 internal surface; In bellows 1 annular groove, be provided with elasticity and strengthen muscle 4; Strengthening muscle 4 is circular member, and Spielpassung between tetrafluoro liner 3 in bellows 1 annular groove.
Strengthen muscle 4 and have two kinds of preferred structure schemes: a kind of is to strengthen the ring 4.2 that surrounds for titanium silk of muscle 4, another kind is that the ring 4.2 that surrounded by elastic metallic yarn of enhancing muscle 4, the tetrafluoro outer lining 4.1 being coated on ring 4.2 form, and what the present embodiment was selected is rear one.
