Description
Technical field
It the utility model is related to a kind of composite soft tube, and in particular to a kind of composite soft tube for conveying space flight oil product.
Background technology
Composite soft tube is a kind of flexible pipe being combined by a variety of high polymer materials, its pliability is good, it is safe and
Using soft handle, because being widely used in the most liquid mediums of conveying.
In general composite soft tube is the conveying for a variety of liquid mediums, and liquid medium conveying is carried out using composite soft tube
When, the liquid mediums conveyed before some more or less can be all remained in composite soft tube, so as to reduce the liquid to be conveyed
The cleanliness factor of medium.Even if composite soft tube is used for the conveying of same liquid medium all the time, in long-time without using composite soft tube
In the case of, the preceding liquid medium that left behind that once conveys may go bad, so as to the liquid once conveyed after influenceing
The cleanliness factor of medium.Conveyed especially for the oil product of space industry, space flight neck is not often reached using current composite soft tube
Requirement of the domain to oil product cleanliness factor.
Utility model content
The purpose of this utility model is to provide a kind of composite soft tube for conveying space flight oil product, and it passes through in pipe shaft inner surface
The interior contact layer formed using PTFE is set, so as to ensure the cleanliness factor of the oil product using composite soft tube conveying, to reach boat
Requirement of its field to oil product cleanliness factor.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of composite soft tube for conveying space flight oil product, it includes pipe shaft, and the pipe shaft is followed successively by interior steel wire, close from inside to outside
Sealing, tensile layer, extexine and outer steel wire, the inner surface of the sealant are provided with an interior contact layer formed using PTFE, should
Interior contact layer is arranged between interior steel wire and sealant.
The outer surface of the interior steel wire is provided with the film formed using PTFE.
A tensile layer is additionally provided between the interior contact layer and sealant.
The composite soft tube also includes joint, and the joint is connected by the end of interior screwed pipe and pipe shaft.
Interior screwed pipe one end jointing, the other end coordinate the end of outer rim sealed connection pipe shaft.
The outer rim is connected to the periphery of interior screwed pipe, and the end of the pipe shaft is interposed in interior screwed pipe by y-type seal ring
Between outer rim.
The utility model is that this uses PTFE shapes using the interior contact layer of PTFE formation in the inner surface setting of composite soft tube
Into interior contact layer coefficient of friction it is extremely low, material is smooth, and material adhesive force is extremely low, easy to clean so that compound soft using this
During pipe transporting oil, the residue of the inner side of composite soft tube is less, will not separate out chemical substance, can ensure in composite soft tube
Cleanliness factor, so as to ensure the cleanliness factor of the oil product of conveying, to reach requirement of the space industry to oil product cleanliness factor.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
For the technology contents of detailed the utility model, architectural feature, institute's reached purpose and effect, embodiment will be enumerated below
And Figure of description is coordinated to be described in detail.
The utility model discloses a kind of composite soft tube for conveying space flight oil product, and it includes pipe shaft 20, and the pipe shaft 20 is by interior
Interior steel wire 5, sealant 8, tensile layer 9, extexine 10 and outer steel wire 11 are outwards followed successively by, one is provided with the inner surface of sealant 8
The interior contact layer 6 formed using PTFE, the interior contact layer 6 are arranged between interior steel wire 5 and sealant 8.
By setting the interior contact layer 6 formed using PTFE between sealant 8 and interior steel wire 5, this is formed using PTFE
Interior contact layer 6 coefficient of friction it is extremely low, material is smooth, and material adhesive force is extremely low, easy to clean so that using the composite soft tube
During transporting oil, the residue of the inner side of composite soft tube is seldom, will not separate out chemical substance, can ensure clean in composite soft tube
Cleanliness, so as to ensure the cleanliness factor of the oil product of conveying.
The film formed using PTFE can also be set in the outer surface of interior steel wire 5, be attached to further reduction compound
The residue of hose inner wall, cleanliness factor inside composite soft tube is improved, the space flight oil product that guarantee is conveyed using the composite soft tube
Cleanliness factor.
In order to improve the intensity of composite soft tube, a tensile layer 7 can also be set again between interior contact layer 6 and sealant 8,
So that how flexible pipe has double-deck tension Rotating fields, compression strength during composite soft tube transporting oil is improved.
The composite soft tube also includes joint 1, and the joint 1 can be connected by interior screwed pipe 2 with the end of pipe shaft 20, interior screwed pipe
2 one end jointings 1, the other end coordinate the end of the sealed connection pipe shaft 20 of outer rim 4.Outer rim 4 is connected to the outer of interior screwed pipe 2
Week, the end of pipe shaft 20 are interposed between interior screwed pipe 2 and outer rim 4 by y-type seal ring 3.
It is of the present utility model it is critical that the utility model composite soft tube inner surface setting be using PTFE formed
Interior contact layer 6, this is extremely low using the coefficient of friction of the PTFE interior contact layers 6 formed, and material is smooth, and material adhesive force is extremely low, easily
In cleaning so that during using the composite soft tube transporting oil, the residue of the inner side of composite soft tube is less, will not separate out chemicals
Matter can ensure the cleanliness factor in composite soft tube, so as to ensure the cleanliness factor of the oil product of conveying, to reach space industry to oil product
The requirement of cleanliness factor.
It is described above, only it is the utility model embodiment, any limit not is made to technical scope of the present utility model
System, therefore every any trickle amendment made according to the technical essence of the utility model to above example, equivalent variations are with repairing
