Abstract
The utility model relates to a high strength anti-explosive fluoroplastic corrugated hose, comprising a fluoroplastic lining, a glass fiber layer, a steel wire braided sleeve, a rubber protective composite film, etc. The high strength anti-explosive fluoroplastic corrugated hose overcomes the defects that ordinary hoses has poor strength and can not prevent explosion, and has the advantages of high-temperature resistance, and corrosion resistance. The utility model can be applied to chemical industries, petroleum chemical industries, metallurgy industries, aviation, coal industries for pipeline connection.
Description
The utility model relates to a kind of high strength anti-explosion fluoroplastic corrugated flexible hose, and anti-corrosion, heatproof pipeline that it is applied to industries such as chemical industry, petrochemical industry, metallurgy, space flight, coal connect.
The spiral fluted flexible pipe only made fluorine plastic tube by known fluoroplastic flexible pipe, and its existence is not withstand voltage, the defective of intensity difference, and in industries that No Open Flames such as chemical industry, petrochemical industry, coals, the defective that its existence can not be explosion-proof, thereby in actual engineering, be difficult to use.
The purpose of this utility model aims to provide a kind of not only anti-corrosion heatproof but also has the fluoroplastic corrugated flexible hose of high strength anti-explosion excellent properties.
The technical solution of the utility model is: get the fluoroplastic internal lining pipe, at the sticking glass fibre layer of its outsourcing.Glass fibre layer is provided with the braided steel wire cover outward, and the braided steel wire cover can be one to five layer, and angle of weave is between 20～80 °.The braided steel wire cover is outer to be rubber protection composite membrane, can have husky muscle or fiber etc. to strengthen composition in the rubber, vulcanizes then outside the braided steel wire cover.The fluoroplastic internal lining pipe is straight tube or spiral groove pipe or annular corrugated barrel, and the straight tube flexibility is low, but withstand voltage situation is better.Spiral groove pipe or annular corrugated barrel flexibility are good, metal ring also can be set to increase compressive strength in its groove.Fluoroplastic are got polytetrafluoroethylene (PTFE) or perfluoroethylene-propylene (FEP) or polychlorotrifluoroethylene (PCTFE) or Meltability polytetrafluorethyletubular (PFA) or polyvinylidene fluoride (PVDF).This flexible pipe is applicable to inside nominal diameter DN10～800, between length 5cm～25m.The flexible pipe two ends are adopted flange to be connected with other mouth of pipe or are threaded.
The anti-corrosion heatproof of the utility model fluoroplastic internal lining pipe energy, the braided steel wire cover has increased intensity, and glass fibre layer is difficult for friction damage liner when making the braided steel wire cover crooked, and rubber protection composite membrane can further improve compressive strength and explosion-proof.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the structural representation that flange connects the high strength anti-explosion fluoroplastic corrugated flexible hose of spiral chute tubular type.Fig. 2 is the high strength anti-explosion fluoroplastic corrugated flexible hose structural representation of straighttube-type of being threaded.Wherein 1 is fluoroplastic internal lining pipe (spiral groove type), the 2nd, and metal strengthens ring, and the 3rd, glass fibre layer, the 4th, braided steel wire cover, the 5th, rubber protection composite membrane, the 6th, adpting flange, the 7th, fluoroplastic internal lining pipe (straight tube), the 8th, connecting thread.Except that above-mentioned two legends, the multiple combining forms such as high strength anti-explosion fluoroplastic corrugated flexible hose that connect straighttube-type such as flange can be arranged also.
The utility model testing property: the highest compression resistance reaches 10MPa when normal temperature, and minimum bending radius is 250mm, can be used for the explosion-proof occasions of industry such as petrochemical industry.
