Description
Technical field
The present invention relates to a kind of line pipe material, specifically a kind of polytetrafluoroethylene (PTFE) pipe fitting.
Background technology
Multiple tube is corrosive liquid mainly for delivery of concentrated nitric acid and chloroazotic acid, although existing multiple tube can reach one
Fixed corrosion resistance, but used with permanent, easily corrode the surface wetting of multiple tube, so as to destroy multiple tube, contracting
Short useful life, in addition, easy extrusion and collision during the use of multiple tube, have impact on the normal use of multiple tube, it is existing
Although the structure protected by reinforcing bar in technology be present, its cost is higher, and installation is inconvenient and barrier propterty is poor.
The content of the invention
The technical problem to be solved in the present invention provides the polytetrafluoro that a kind of easy for installation, barrier propterty is good and service life is grown
Ethene pipe fitting.
In order to solve the above-mentioned technical problem, polytetrafluoroethylene (PTFE) pipe fitting of the invention, including the steel-tube construction layer of outer layer and
The both ends of steel-tube construction layer are welded with adpting flange, have in steel-tube construction layer and adpting flange by steel-tube construction layer and company
The polytetrafluoroethylmaterial material layer that acting flange directly coats, it is provided with positioned at steel pipe knot between the adpting flange at steel-tube construction layer both ends
The steel wire of the peripheral tubular of structure layer, the edge of steel wire are provided with the flange for cutting expansion, and the flange of steel wire passes through two halves
The pressing plate of opening structure is pressed in the end face outside of adpting flange.
Going back compound coating in the polytetrafluoroethylmaterial material layer has polyolefin undercoating.
The connection end of the steel-tube construction layer and adpting flange is provided with arc angling.
The flange of the steel wire is in-flanges or flanging.
After above-mentioned structure, due to having in steel-tube construction layer and adpting flange by steel-tube construction layer and adpting flange
The polytetrafluoroethylmaterial material layer and polyolefin undercoating directly coated, so that anti-corrosion capability is strong, steel-tube construction layer two
The steel wire of the peripheral tubular positioned at steel-tube construction layer is provided between the adpting flange at end, on the one hand can utilize wire netting
Gap outer surface of tube body is carried out it is ventilative will not cause outer surface of tube body by altitude temperature difference effect in liquid delivery process by cargo sweat,
The flexible protective capacities for forming higher-strength of another further aspect also steel wire itself, avoids body and is squeezed collision, separately
Outside, it uses the connected mode of pressing plate that wire netting installation is changed convenient, reduces replacement cost, improves economic benefit.
Brief description of the drawings
Fig. 1 is the partial structural diagram of polytetrafluoroethylene (PTFE) pipe fitting of the present invention；
Fig. 2 is the structural representation of polytetrafluoroethylene (PTFE) pipe fitting center platen of the present invention and wire netting impaction state.
Embodiment
With reference to the accompanying drawings and detailed description, the polytetrafluoroethylene (PTFE) pipe fitting of the present invention is described in further detail.
As illustrated, this polyfluortetraethylene pipe part of the present invention, include the steel-tube construction layer 1 and steel-tube construction layer 1 of outer layer
Both ends be welded with adpting flange 2, have in steel-tube construction layer 1 and adpting flange 2 by steel-tube construction layer 1 and adpting flange
The 2 polytetrafluoroethylmaterial material layers 3 directly coated, going back compound coating in polytetrafluoroethylmaterial material layer 3 has polyolefin undercoating 7, by
Scheme visible, polytetrafluoroethylmaterial material layer 3 and polyolefin undercoating 7 coat steel-tube construction layer 1 and adpting flange 2 completely, thus
The close reliability of connection is improved, not only prevents in liquid delivery process and flange connections is corroded, is improved anti-
Shield ability, service life is extended, also with certain sealing property, further ensure the connection reliability of body, steel pipe
The steel wire 4 of the peripheral tubular positioned at steel-tube construction layer 1 is provided between the adpting flange 2 at the both ends of structure sheaf 1, steel wire 5
Edge is provided with the flange 5 for cutting expansion, and the flange of steel wire 5 is pressed on adpting flange by two halves to the pressing plate 6 of opening structure
End face outside on.
Further, the connection end of described steel-tube construction layer 1 and adpting flange 2 is provided with arc angling 8, steel wire
Flange 6 is in-flanges or flanging, the flange 6 of steel wire is pressed between adpting flange and pressing plate in connection procedure, then
Adpting flange and pressing plate are connected by fastener.
