Description
Technical field
The utility model is related to combustion gas transport field, more particularly to a kind of transport pipelines for filtering natural gas.
Background technology
The transport of natural gas is mainly based on pipeline transportation.In natural gas after exploitation often with have some solid particles and
The impurity such as liquid.These impurity can cause the noise in line clogging and transportational process.Filter device in existing delivery tube
General replacement process is more complex.After filter screen is blocked by impurity, it is unfavorable for the replacement and cleaning of filter screen.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of transport pipelines for filtering natural gas, to ensure
On the basis of leakproofness between pipeline, the convenience for replacing filter screen is improved.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of transport pipeline for filtering natural gas, including：First pipe, second pipe and filter screen, described first
Pipeline is made of connecting pin and pipeline, and the internal diameter of the connecting pin is matched with the outer diameter of the second pipe, the pipeline
Internal diameter is identical as the internal diameter of the second pipe, and installation screens, the installation are provided between the connecting pin and the pipeline
The internal diameter of screens is more than the internal diameter of the connecting pin, and the filter screen has wire side and the installation in wire side circumferential direction is arranged
Circle, the filter screen are fixed on the installation screens by the installing ring.
Preferably, the installation screens is less than the thickness of the installing ring along the width of the center line of the first pipe
Degree.
Preferably, it is provided with reinforcing rib between the outside of the first pipe, the connecting pin and the pipeline.
Preferably, it is provided with washer between the circumferential and described filter screen of the second pipe.
Preferably, the inner wall of the connecting pin is provided with internal thread, be provided on the outside of the second pipe with it is described interior
The matched external screw thread of screw thread.
Preferably, the connecting pin, the installation screens, the pipeline and the reinforcing rib are integrally formed.
Compared with prior art, the beneficial effects of the utility model are：Since installation screens is equivalent to connecting pin and pipe
One groove on road, and the installing ring of filter screen and installation screens interference fit, therefore, filter screen is not easy after completing to fix
It is displaced.Simultaneously, it is only necessary to second pipe be removed from connecting pin, installing ring is then separated into installation screens, it will be able to real
The dismounting of existing filter screen.Therefore, the utility model can improve on the basis of the leakproofness between ensureing pipeline and replace filtering
The convenience of net.
Description of the drawings
Some specific realities of the utility model are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter
Apply example.Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing：
Fig. 1 is a kind of connection diagram for filtering the transport pipeline of natural gas of the utility model；
Fig. 2 is a kind of dismantling schematic diagram for filtering the transport pipeline of natural gas of the utility model.
Meaning in figure represented by each symbol is as follows：
1- first pipes, 2- second pipes, the connecting pins 3-, 4- installation screens, 5- filter screens, 51- wire sides, 52- installing rings,
6- washers, 7- reinforcing ribs.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As depicted in figs. 1 and 2, the utility model is used to filter the transport pipeline of natural gas, includes mainly：First pipe 1,
Second pipe 2 and filter screen 5.The first pipe 1 is made of connecting pin 3 and pipeline.The internal diameter of the pipeline and described second
The internal diameter of pipeline 2 is identical.In order to which second pipe 2 is installed in first pipe 1, the internal diameter of the connecting pin 3 and described second
The outer diameter of pipeline 2 matches, that is to say, that the internal diameter that the internal diameter of connecting pin 3 is equivalent to the second pipe 2 adds second pipe
The sum of 2 wall thickness.The external thread structure for installation is provided on the outside of one end of second pipe 2.The inner wall of connecting pin 3 is same
It is provided with the internal thread structure for installation.External thread structure and external thread structure match, and second pipe 2 is screwed in and is connected
End 3.
Installation screens 4 is provided between the connecting pin 3 and the pipeline.The internal diameter of the installation screens 4 is more than institute
The internal diameter of connecting pin 3 is stated, therefore, installation screens 4 is equivalent to the groove between connecting pin 3 and pipeline.And filter screen 5 has net
Face 51 and the installing ring 52 circumferential in the wire side 51 is set.The filter screen 5 can be fixed on institute by the installing ring 52
State installation screens 4.Wherein, the installation screens 4 is less than the installing ring 52 along the width of the center line of the first pipe 1
Thickness, the installation screens 4 and installing ring 52 are interference fitted, are shifted under the impact of air-flow to avoid filter screen 5.In order to add
It is strong it is fixed after filter screen 5 stability, be provided with washer 6 between the circumferential and described filter screen 5 of the second pipe 2.
Since the inner diameter size of installation screens 4 and pipeline is different, screwing in the second pipe 2 of connecting pin 3 can be incited somebody to action by washer 6
Filter screen 4 is pressed in first pipe 1.
And reinforcing rib 7 is provided between the outside of the first pipe 1, the connecting pin 3 and the pipeline, with enhancing
The intensity of junction.And in order to ensure the leakproofness of pipeline, the connecting pin 3 of the utility model, installation screens 4, pipeline and
Reinforcing rib 7 is integrally formed.
To sum up, since installation screens 4 is equivalent to a groove of connecting pin 3 and pipeline, and the installing ring 52 of filter screen 5
It is interference fitted with installation screens 4, therefore, filter screen 5 is not susceptible to shift after completing to fix.Simultaneously, it is only necessary to by the second pipe
Road 2 is removed from connecting pin 3, installing ring 52 is then separated installation screens 4, it will be able to realize the dismounting of filter screen 5.Therefore, originally
Utility model can improve the convenience for replacing filter screen on the basis of the leakproofness between ensureing pipeline.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
