Description
Technical field
The utility model is related to a kind of thin-walled polytetrafluoroethylene (PTFE) tube assemblies.
Background technology
It needs to connect with steel plate when polyfluortetraethylene pipe uses, traditional polyfluortetraethylene pipe modular construction makes polytetrafluoro
When ethylene tube is connect with steel plate, flange is carried out frequently with turn-up device line up, processes boss on the steel plate, is then filled by compressing
It sets and pipe is fixed together.The gas that will produce some when this mode flange, endangers personal safety, also will produce at flange
Certain material hardening, since flanging device is larger, can only generally process, working at height is difficult on ground.It is therefore proposed that this reality
With novel.
Utility model content
For the above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of thin-walled polyfluortetraethylene pipe
Thin-walled polyfluortetraethylene pipe is closely connect with tube sheet by the way of expanded joint, is easy to operate, effectively being improved work by component
Make efficiency.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions：
A kind of thin-walled polytetrafluoroethylene (PTFE) tube assembly, including thin-walled polyfluortetraethylene pipe, sealing bolt and tube sheet, the tube sheet
With several holes, one end of the thin-walled polyfluortetraethylene pipe passes through tube sheet, the other end of thin-walled polyfluortetraethylene pipe to be set with
On sealing bolt.
The sealing bolt includes bolt top, bolt middle part and bolt lower part, and the bolt top is octagonal trepanning, and
Bolt top is equipped with external screw thread, is the conical surface in the middle part of bolt, and bolt lower part is cylindrical surface；The hole includes hole top, in the middle part of hole and
Hole lower part, the hole top are equipped with internal thread, and the internal thread is engaged with external screw thread, are matched with bolt middle part in the middle part of the hole,
The hole lower part is matched with bolt lower part.
The beneficial effects of the utility model are as follows：
The thin-walled polytetrafluoroethylene (PTFE) tube assembly of the utility model, it is simple in structure it is convenient, be not limited by a space and safety collar
Protect, thin-walled polyfluortetraethylene pipe and sealing bolt, tube sheet assembling it is easy to operate, securely and reliably, can be applicable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 and 3 is the structural schematic diagram of the sealing bolt in the utility model；
Fig. 4 is the structural schematic diagram of the tube sheet in the utility model；
Wherein, 1 be thin-walled polyfluortetraethylene pipe, 2 be sealing bolt, 21 be bolt top, 22 be in the middle part of bolt, 23 be spiral shell
Bolt lower part, 3 be tube sheet, 4 be hole, 41 be hole top, 42 be in the middle part of hole, 43 be hole lower part.
Specific implementation mode
The utility model is further described with reference to specific embodiment, but the scope of protection of the utility model is simultaneously
It is without being limited thereto.
As shown in Figs 1-4, the thin-walled polytetrafluoroethylene (PTFE) tube assembly of the utility model, including it is thin-walled polyfluortetraethylene pipe 1, close
Bolt 2 and tube sheet 3 are sealed, there are tube sheet 3 several holes 4, one end of thin-walled polyfluortetraethylene pipe 1 to pass through tube sheet 3, thin-walled polytetrafluoro
The other end of ethylene tube 1 is sleeved on sealing bolt 2, seals thin-walled polytetrafluoroethylene (PTFE) 1 and tube sheet 3 finally by threaded engagement
It is fixed.
Further it is arranged：
Sealing bolt 2 in the utility model includes bolt top 21, bolt middle part 22 and bolt lower part 23, bolt top
21 be octagonal trepanning, and bolt top 21 is equipped with external screw thread, and 22 be the conical surface in the middle part of bolt, and bolt lower part 23 is cylindrical surface.
Hole 4 includes that hole top 41, hole middle part 42 and hole lower part 43, hole top 41 are equipped with internal thread, internal thread and external screw thread
Engagement, hole middle part 42 are matched in the middle part of bolt 22, and hole lower part 43 is matched with bolt lower part 23.
The utility model it is simple in structure it is convenient, be not limited by a space and safety and environmental protection, thin-walled polyfluortetraethylene pipe and sealing
Bolt, tube sheet assembling it is easy to operate, securely and reliably, can be applicable.
Above-described embodiment is only used for illustrating the inventive concept of the utility model, rather than to the utility model rights protection
Restriction, all non-essential modifications to the present invention made by this concept should all fall into the protection model of the utility model
It encloses.
