Abstract
The utility model discloses a metal collapsible tube, including the stainless steel body, its characterized in that: be provided with the inoxidizing coating on the inner wall of stainless steel body, the inoxidizing coating is from interior to including polytetrafluoroethylene layer, nylon layer, aluminium lamination, EVA layer, PVC layer outward in proper order, the cladding has the EVOH layer on the outer wall of stainless steel body, by adopting the above technical scheme, coefficient of friction is little on the polytetrafluoroethylene layer, can reduce and the cable between wearing and tearing, the nylon layer pliability is good, the difficult fracture of the metal collapsible tube that can when metal collapsible tube buckles be, the intensity of protective layer is guaranteed to the aluminium lamination, and aluminium lamination itself has good ductility, the EVA layer have good take precautions against earthquakes, the shock -absorbing capacity, the PVC layer is corrosion -resistant, waterproof, the EVOH layer is heat -resisting wear -resisting, and has good elasticity.
Description
Technical field
The utility model relates to a kind of metallic hose.
Background technique
Metallic hose is the important composition parts in modern industrial equipment connecting line, and metallic hose is used as electric wire, cable, the electric wire protective tube of instrument and meter for automation signal and civilian shower hose etc.
Present metallic hose entirety adopts stainless steel material to make, and have stronger corrosion resistance, but its pliability, ductility is poor, and easily weares and teares.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide more durable metallic hose.
For achieving the above object, the utility model provides following technological scheme: a kind of metallic hose, comprise stainless steel body, the inwall of described stainless steel body is provided with protective coating, described protective coating comprises polytetrafluoroethylene floor, nylon layer, aluminium lamination, EVA layer, layer of PVC from the inside to the outside successively, and the outer wall of described stainless steel body is coated with evoh layer.
By adopting technique scheme; polytetrafluoroethylene floor friction factor is little; can reduce the wearing and tearing between cable, nylon layer pliability is good, the metallic hose not easy-rupturing that can be when metallic hose bending; aluminium lamination ensures the intensity of protective layer; and aluminium lamination itself has good ductility, EVA layer has good shockproof, shock-absorbing capacity, and layer of PVC is corrosion-resistant, waterproof; evoh layer heat-resistant antifriction, and there is good stretchability.
Further, the thickness proportion of described polytetrafluoroethylene floor, nylon layer, aluminium lamination, EVA layer, layer of PVC is 2:2:1:1:3.
Pass through technique scheme: the thinner of aluminium lamination setting is conducive to the bending of metallic hose, and teflon thickness is a bit passable, although polytetrafluoroethylene floor friction factor is low, in use still can wear and tear.
Further, described aluminium lamination is provided with aperture along stainless steel body axial and circumferential uniform intervals.
By technique scheme: aluminium lamination has enough deformation spaces when bending.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model metallic hose;
Fig. 2 is the schematic cross-section of A-A in Fig. 1;
Fig. 3 is the enlarged view in B region in Fig. 2.
Reference character: 1, stainless steel body; 2, flange; 3, protective coating; 31, polytetrafluoroethylene floor; 32, nylon layer; 33, aluminium lamination; 34, EVA layer; 35, layer of PVC; 4, evoh layer.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model metallic hose embodiment is described further.
A kind of metallic hose, comprise stainless steel body 1, be arranged on the flange 2 at stainless steel body 1 two ends, the inwall of stainless steel body 1 is provided with protective coating 3, described protective coating 3 comprises polytetrafluoroethylene floor 31 from the inside to the outside successively, nylon layer 32, aluminium lamination 33, EVA layer 34, layer of PVC 35, polytetrafluoroethylene floor 31, nylon layer 32, aluminium lamination 33, EVA layer 34, the thickness proportion of layer of PVC 35 is 2:2:1:1:3, concrete, the thickness of polytetrafluoroethylene floor 31 is 0.2mm, aluminium lamination 33 is provided with aperture along stainless steel body 1 axial and circumferential uniform intervals, aperture is circular aperture, the outer wall of described stainless steel body 1 is coated with evoh layer 4, the thickness of evoh layer 4 is 0.2mm.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
