Description
Technical field
The utility model is related to a kind of Fluorine-lined pipeline, and in particular to a kind of resistance to high-vacuum fluorine-lined pipeline of high temperature resistant.
Background technology
Pipeline is mainly used in the transmission of flowing material, but causes pipe internal memory for high-temperature medium and fluid flow deficiency
When being used under conditions of vacuum, there are problems that as follows, if the temperature of fluid is too high, use for a long time will reduce pipeline
Bulk strength simultaneously makes overall softening, or even expendable plastic deformation occurs, so that a period of time that works must rest one section
Time, so as to the service efficiency for substantially reducing, when fluids within pipes flow is inadequate in addition there is vacuum phenomenon in pipeline, and this can make
Obtain pipeline to be under pressure, pipeline is easily deformed under such circumstances for long-term work, so as to substantially reduce the service life of pipeline.
Utility model content
In order to solve defect present in prior art, the utility model provides a kind of resistance to high-vacuum fluorine-lined pipe of high temperature resistant
Road.
It is as follows that the utility model solves the technical scheme that its technical problem used：
A kind of resistance to high-vacuum fluorine-lined pipeline of high temperature resistant, it is characterised in that：Including steel pipe, steel pipe Fluorine-lined layer, end flange, dredge
Port flange, end cap and end cap Fluorine-lined layer；The steel pipe uses seamless steel pipe, and two end flanges are welded on steel pipe two
End, is lining in steel pipe in the steel pipe Fluorine-lined layer, the steel pipe Fluorine-lined layer two ends turn up to form sealing surface both with respect to end flange；
There is a dredge outlet in the middle of the steel pipe, dredge outlet end is welded with dredge outlet flange, and the steel pipe Fluorine-lined layer extends to dredging
Simultaneously turn up to form sealing surface on dredge outlet end in mouth end；The end cap is connected by bolt with dredge outlet flange, in end cap
End cap Fluorine-lined layer is lined with, end cap Fluorine-lined layer is in close contact with the sealing surface on dredge outlet end, so as to ensure the sealing of dredge outlet.
Further illustrate, steel pipe Fluorine-lined layer and end cap Fluorine-lined layer material are polytetrafluoroethylene (PTFE), polytetrafluoro in the utility model
Ethene has the superior performance such as high temperature resistant, low temperature resistant, corrosion-resistant, and big using pressure limit, can be under vacuum, subnormal ambient
Keep superperformance.Polytetrafluoroethylene (PTFE) is coefficient of friction the lowest in solid material, and surface tension very little, and any thing is not adhered to
Matter, so as to substantially reduce the friction of tube fluid and tube wall, the heat for producing that rubs is ignored, and pipeline is extra without being subjected to
Heat.
Further illustrate, steel pipe is brought into close contact with steel pipe Fluorine-lined layer in the utility model, leaves no gaps, high in seamless steel pipe
Under rigidity, the support of high intensity, the anti-negative pressure ability of steel pipe Fluorine-lined layer is further strengthened, and deformation is not susceptible to, such that it is able to resistance to height
Vacuum.
Further illustrate, steel pipe Fluorine-lined layer and end cap Fluorine-lined layer is according to different technique and uses work in the utility model
Condition, thickness is 2~5mm.
