Abstract
The utility model discloses a negative-pressure-resistant reinforced metal hose pipe which comprises a corrugated pipe, a net body and a tetrafluoroethylene lining, wherein the corrugated pipe forms a body of the metal hose pipe, the outer wall of the corrugated pipe is sleeved with the net body, and the tetrafluoroethylene lining is attached to the inner surface of the corrugated pipe. Elastic reinforcing ribs are arranged in corrugated pipe ring grooves, and the reinforcing ribs are circular-ring-shaped components and in clearance fit with the tetrafluoroethylene lining in the corrugated pipe ring grooves. The negative-pressure-resistant reinforced metal hose pipe is characterized in that the reinforcing ribs are loops formed by titanium wires in a defined mode or composed of loops formed by elastic metal wires in a defined mode and tetrafluoroethylene outer linings covering the loops. The tetrafluoroethylene lining is pressed by the reinforcing ribs, and even under the action of negative pressure, the tetrafluoroethylene lining can not deform, so that normal use of the lining tetrafluoroethylene metal hose pipe is ensured, meanwhile, the strength of the metal hose pipe is increased through the reinforcing ribs, and service life of the negative-pressure-resistant reinforced metal hose pipe is significantly prolonged.
Description
Technical field
The utility model relates to a kind of metallic hose, and specifically, the utility model relates to a kind of corrugated flexible metal tube.
Background technique
The main body of corrugated flexible metal tube is bellows, for the protection bellows, generally is set with dictyosome at its outer wall, needs the corrosion-resistant use occasion for some, then at bellows inside surface applying 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 defective: when being applied to the pipe-line system of negative pressure, negative pressure in the pipeline may make the tetrafluoro liner produce distortion, thus the normal use of impact lining tetrafluoro corrugated flexible metal tube.
The model utility content
The utility model is for the deficiencies in the prior art, even a kind of reinforced metal of anti-negative pressure flexible pipe that the tetrafluoro liner also can not be out of shape under suction function is provided.
The utility model is achieved through the following technical solutions technical goal.
The reinforced metal of anti-negative pressure flexible pipe, it comprises bellows, the dictyosome that is sleeved on the bellows outer wall that consists of its main body, the tetrafluoro liner that is fitted in bellows inside surface; Its improvements are: be provided with elasticity and strengthen muscle in the bellows annular groove; Described enhancing muscle is circular member, cooperates with tetrafluoro liner gap in the bellows annular groove.
The utility model further improves and is: described enhancing muscle is the ring that the titanium silk surrounds.
Another kind of further improvement of the utility model is: the ring that described enhancing muscle is surrounded by elastic metallic yarn, the tetrafluoro outer lining that is coated on the ring form.
The utility model compared with prior art has following good effect:
1, in the bellows annular groove, is provided with elasticity and strengthens muscle, push down the tetrafluoro liner by strengthening muscle, like this, even the tetrafluoro liner can not be out of shape yet under suction function, thereby guaranteed the normal use of lining tetrafluoro metallic hose, increased simultaneously the intensity that muscle has also increased metallic hose.
2, strengthening muscle is the ring that the titanium silk surrounds, and the antiseptic property of titanium silk is better, also has preferably antiseptic property so that strengthen muscle.
3, the ring outer wall of enhancing muscle is coated with the tetrafluoro outer lining, has increased layer protective layer between enhancing muscle 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.
The reinforced metal of anti-negative pressure flexible pipe shown in the drawings, it comprises bellows 1, the dictyosome 2 that is sleeved on bellows 1 outer wall that consists of its main body, the tetrafluoro liner 3 that is fitted in bellows 1 internal surface; In bellows 1 annular groove, be provided with elasticity and strengthen muscle 4; Strengthening muscle 4 is circular member, cooperates with tetrafluoro liner 3 gaps in bellows 1 annular groove.
Strengthen muscle 4 two kinds of preferred structure schemes are arranged: a kind of is to strengthen the ring 4.2 that muscle 4 surrounds for the titanium silk, and another kind is that the ring 4.2 that surrounded by elastic metallic yarn of enhancing muscle 4, the tetrafluoro outer lining 4.1 that is coated on the ring 4.2 form, and what present embodiment was selected is rear a kind of.
