Abstract
The utility model relates to a polytetrafluorethylene screwed hose. The utility model is characterized in that the outer side of the polytetrafluorethylene screwed hose is bushed with a metallic net. The polytetrafluorethylene screwed hose overcomes the defect that the original common hose has poor ability of resisting the positive pressure and has the advantages of resistant high pressure of the metal corrugated hose as well as good anticorrosion property of the polytetrafluorethylene screwed hose.
Description
The utility model relates to a kind of teflon screw thread flexible pipe.
When the line transportation of the gas-liquid phase acid-base material under corrosion-resistant shockproof occasion and equipment arranged in dislocation, usually use teflon screw thread flexible pipe, though this teflon screw thread flexible pipe has good antiseptic property, but owing to be subjected to the restriction of itself material, can not bear higher pressure, malleation particularly, in order to address this problem, the patent No. is 93210948.9, denomination of invention is the teflon screw thread flexible pipe that the patent application document of teflon screw thread flexible pipe discloses a kind of outer lining rubber, though this screw thread flexible pipe has improved the anti-malleation ability of product to a certain extent, but in some high pressure occasions, its anti-malleation ability is still unsatisfactory.
The purpose of this utility model provides the higher teflon screw thread flexible pipe of a kind of anti-malleation performance.
Technical solution of the present utility model is one or more layers wire netting of outside lining at common teflon screw thread flexible pipe.
Below in conjunction with drawings and Examples detailed content of the present utility model is described:
Accompanying drawing is a structural representation of the present utility model.
Internal layer of the present utility model is to push the teflon screw thread flexible pipe (1) that forms by the rotation of spiral centre of form mould and external mold again be heated to softening plastic temperature by the polyfluortetraethylene pipe embryo is heated after, at one or more layers wire netting of outside lining (2) of teflon screw thread flexible pipe (1), as steel wire.In some high pressure occasions, because the protection of wire netting (2), make teflon screw thread flexible pipe (1) unlikely breaking and influence normal production.The configurable as required flange plate (3) that has bolt hole (5) in the two ends of teflon screw thread flexible pipe, and carry out flange and handle back formation flange gasket (4) to make things convenient for interconnecting of pipeline enclosure, certainly, this Placement also can adopt screw socket to connect.
The utility model since at the outside lining of teflon screw thread flexible pipe wire netting, therefore improved the anti-malleation performance of teflon screw thread flexible pipe greatly, enlarged application area.Make it not only have the high voltage bearing advantage of metal bellow but also have the good advantage of teflon screw thread flexible pipe antiseptic property.
Claims (1)
1, a kind of teflon screw thread flexible pipe is characterized in that one or more layers wire netting of outside lining (2) at teflon screw thread flexible pipe (1).
