Description
Technical field
The one kind that the utility model is related to machining technology field is fastenedly connected component, more particularly to a kind of sealed
Change pipe joint.
Background technology
In airplane parts design, some influence the particularity of the oil and gas path portion structure of Flight Safety, typically all
It is required that connected by pipe joint.Because the difference of line size and size is badly in need of one kind and changes pipe joint realizing, simultaneously as
The petroleum system of aircraft is all higher to sealing requirements, once leakage will, the whole safety of aircraft will be directly affected.And
Some irregular narrow positions, the pipeline of same size size are can not to meet installation requirement.Particularly aircraft, rocket etc.
The pipeline connected mode of high-speed aircraft be all it is diversified, and common pipe joint easily occur releasing in use,
The shortcomings of leakage, sealing effectiveness difference, it is most important that do not possess translation function.It can only use and be directly connected in conventional designer
Mode installed, because pipeline is long, cause installer extremely onerous when installing again；All compare when line size selects
More single, some designers are also attached by the way of directly welding, have the shortcomings that this connected mode it is a lot, such as
Some positions are to need often dismounting detection, this mode to be unable to handle, and it is inconvenient to safeguard, it is difficult to changes；Using welding meeting
In the presence of some tiny weld seams or hole, good sealing effectiveness is not had, many potential safety hazards be present.When in civilian industry also
Analogue is commonly encountered, limitation is brought to whole pipeline connection area.A kind of structure type is provided for this utility model
Can solve a kind of sealed conversion pipe joint of above-mentioned problem.
Utility model content
The purpose of this utility model is to provide a kind of sealed conversion pipe joint, is not had well with solving prior art
Sealing effectiveness, the technical problem of many potential safety hazards be present.
What the utility model was realized in：
A kind of sealed conversion pipe joint, it is included in external screw thread and is provided with outer oblique cone degree, is provided with internal thread interior oblique
The structure of taper.
Specifically, the conversion pipe joint is used to connect various sizes of pipeline one and pipeline two, the conversion pipe joint includes
As the hexahedron at twisting position, external screw thread and internal thread are respectively equipped with the hexahedron both ends, is provided with externally threaded end
Outer oblique cone degree, interior oblique cone degree is provided with interior threaded interior, the circular hole for being used for conveying liquid or gas is provided with inside the hexahedron.
Further, the external diameter of the hexahedron is more than the externally threaded external diameter.
A kind of method that seal for pipe joints and connection are carried out using above-mentioned sealed conversion pipe joint, including the sealed conversion
The threaded connection method that pipe joint is combined using external screw thread and internal thread.Also include sealed conversion pipe joint and use outer oblique cone degree
With the oblique cone degree encapsulating method of interior oblique cone degree combination.Also include sealed conversion pipe joint and liquid or gas are conveyed using circular hole
Body.
Compared with prior art, sealed conversion pipe joint of the present utility model is mainly used in carry out not during pipeline connection
With the conversion between size, it is easily installed and safeguards, avoids unification design of the designer on pipe connecting method：No
With the welding manner between size；It is directly connected between similar sizes.This is one of key of the present utility model.Secondly, also
It can prevent liquid or gas from being leaked from junction, there is good sealing effectiveness.This is the two of key of the present utility model.Cause
This utility model can substitute the connected mode between former pipeline and pipeline.And it convenient and swift can be installed and be safeguarded.
The utility model can reduce the connection difficulty between modern pipeline and pipeline due to taking above technical scheme, and and can obtains
Good sealing effectiveness is obtained, and security reliability is high, installs and easy to maintenance.
Brief description of the drawings
Fig. 1 is the structural representation of the sealed conversion pipe joint of the utility model；
Fig. 2 is exemplary application map of the present utility model.
Description of reference numerals：1- hexahedrons, 2- external screw threads, the outer oblique cone degree of 3-, 4- internal threads, oblique cone degree in 5-, 6- circular holes,
7- pipelines one, 8- pipelines two.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：
As depicted in figs. 1 and 2, conversion pipe joint of the present utility model is to be used to connect various sizes of pipeline 1 and pipe
Road 28, in Fig. 2, pipeline 1 is located at the left side of the conversion pipe joint, and pipeline 28 is located at the right side of the conversion pipe joint.
The conversion pipe joint includes the hexahedron 1 as twisting position, and external screw thread 2 is respectively equipped with the both ends of hexahedron 1
With internal thread 4, outer oblique cone degree 3 is provided with the end of external screw thread 2, interior oblique cone degree 5 is provided with inside internal thread 4, in the hexahedron 1
Inside is provided with the circular hole 6 for being used for conveying liquid or gas.
Pipeline 1 is provided with the screw thread and taper matched with internal thread 4 and interior oblique cone degree 5, and pipeline 28 is provided with and external screw thread 2
With the screw thread and taper of the matching of outer oblique cone degree 3.
When the utility model is implemented, pass through interior oblique cone degree 5 and outer oblique cone degree 3 end face with pipeline 1 and pipeline 28 respectively
Coordinate, its pipeline is connected by internal thread 4 and external screw thread 2, fixation is tightened by hexahedron 1, finally realize that its sealing is made
With passing through circular hole 6 after the completion of sealing and convey liquid or gas.
Certainly, it is above concrete application example of the present utility model, the utility model also has other embodiments, all
The technical scheme formed using equivalent substitution or equivalent transformation, all fall within the protection domain required by the utility model.
