Fig. 2 is the A portions enlarged drawing in the present invention.
Embodiment
To make the object, technical solutions and advantages of the present invention of greater clarity, with reference to embodiment and join
According to accompanying drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hair
Bright scope.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring this
The concept of invention.
Fig. 1, Fig. 2, tipping formula pipeline 100 provided by the present invention, including the first pipeline 10 are referred to, with respect to the first pipeline
10 the second pipelines 20 set, and for connecting the pipeline connection mechanism of the first pipeline 10 and the second pipeline 20.It is wherein described
First pipeline 10 and any two part that the second pipeline 20 is tipping formula pipeline 100, in practice, the first pipeline 10 and second
The caliber of pipeline 20 may be configured as equally, may be alternatively provided as different, the first pipeline 10 and the second pipeline 20 in the present embodiment
Pipe diameter size it is identical.
In the present embodiment, on the one hand the pipeline connection mechanism is to be used to connect the first pipeline 10 and the second pipeline 20
, with overcome the first pipeline 10 and the second pipeline 20 during the use because expand with heat and contract with cold and caused by pipeline cracking.
Specifically, the pipeline connection mechanism includes telescoping tube 31, the first bellows 32, counter flange disk 33, the second ripple
The bellows 35 of line pipe 34 and the 3rd.The telescoping tube 31 is interconnected with the first pipeline 10 and the second pipeline 20, wherein stretching
The flange end 311 of the draw 31 is fixedly connected with the flange end 11 of the first pipeline 10, and the part of pipeline end 312 of telescoping tube 31 is stretched
Enter to the second pipeline 20, and the telescoping tube 31 stretches to the external diameter of pipeline end 312 of the second pipeline 20 less than the described second pipe
The internal diameter on road 10.First bellows 32, counter flange disk 33, the second bellows 34 are set in the outside of telescoping tube 31.
Wherein, the flange end 311 of first bellows 32 and telescoping tube 31 is connected, and the other end is and transition method
The first end 331 of blue disk 33 is fixedly connected；Second end 332 and second pipeline of second bellows 34 with counter flange disk 33
Be attached fixation with stay bolt (not shown) between 20 flange end 21, so when pipeline connection mechanism normal in use,
Second bellows 34 is connected by stay bolt, is not involved in the first pipeline 10 and is given birth to the second pipeline 20 when being expanded with heat and contract with cold
The telescopic shape change of production, specifically offsets realization with the first bellows 32.The ripple of second bellows 34 in the present embodiment
The ripple being preferably arranged on one, and second bellows 34 is set relative to the evagination of telescoping tube 31, is so avoided
When pipeline connection mechanism connects the first pipeline 10 and the second pipeline 20 and participates in medium and convey, its ripple in the second bellows 35
Hydrops is formed on wall.And the ripple of the first bellows 32 be set to it is multiple, it is heated to offset the first pipeline 10 and the second pipeline 20
Produced telescopic shape change during swollen shrinkage.
From the foregoing, it will be observed that first bellows 32, counter flange disk 33, the second bellows 34 and the second pipeline 20 are mutual
Connection.Such first pipeline 10, the pipeline 20 of telescoping tube 31 and second are being interconnected and realized to medium (liquid or gas thing
Material) conveying when, medium can also enter to the first bellows 32 by the second bellows 34 and counter flange disk 33, and medium whether
Can enter to the bellows 32 of counter flange disk 33 and first be specifically on counter flange disk 33 second end 332 apart from telescoping tube
Passage that spacing between 31 upper pipeline ends 312 is formed is realized.Therefore, the present embodiment is located at the second ripple in telescoping tube 31
A flange collar 313, wherein pipeline end of the flange collar 313 preferably with telescoping tube 31 are fixed with pipeline end 312 at the position of line pipe 34
312 are set to integral structure；And the height of the flange collar 313 is more than the second end 332 and the telescoping tube of the counter flange disk 33
Spacing between 31 upper pipeline ends 312, that is, the pile extension formula pipeline 100 is when in use, because the second bellows 34 has in itself
Concertina type, so can drive counter flange disk 33 close towards the second pipeline 20 by stay bolt, until on counter flange disk 33
The second end 332 be resisted against in the flange collar 313 at the upper pipeline end 312 of telescoping tube 31, and finally realize the medium in the second pipeline 20
It will be separated by the second end 332 of flange collar 313 and counter flange disk 33.
3rd bellows 35 is applied in the pipeline connection mechanism, is to be used to substitute when the Cracking Failure of the first bellows 32
The deformation quantity that the first pipeline 10 and the second pipeline 20 are produced because expanding with heat and contract with cold is offset with the 3rd bellows 35 afterwards.Described 3rd
Bellows 35 is socketed on the first pipeline 10, wherein, one end of the 3rd bellows on the first pipeline 10 with being fixed with
Flange plate 12 be fixedly connected, the other end is fixedly connected with the first bellows 32.And when the 3rd bellows 35 is assembled to the
When on one pipeline 10, the ripple of the 3rd bellows 35 is in tightening state.That is, the 3rd bellows 35 is in pressure
It is assembled in the state of contracting on pipeline 100.
In the present embodiment, the 3rd bellows 35 is provided in the outside of the flange end 311 of telescoping tube 31, and described
The flange end 11 of one pipeline 10, the flange end of the bellows 32 of flange end 311 and first of telescoping tube 31 offer multiple one respectively
One corresponding screwed hole (not shown), and it is attached fixation with many first bolt (not shown).Such pipeline connecting machine
Structure is applied normally to be used on tipping formula pipeline 100, and the first pipeline 10 and the second pipeline 20 can be offset with the first bellows 32
The deformation quantity produced because expanding with heat and contract with cold.And when the first bellows 32 ruptures, the first bolt can be turned, make the first pipeline
10 flange end 11 departs from the flange end 311 of telescoping tube 31, and the method for the bellows 32 of flange end 311 and first of telescoping tube 31
Lan Duan is fixedly connected, further, and annular array is used between the bellows 32 of flange end 311 and first of the telescoping tube 31
The second bolt (not shown) be attached fixation.To ensure people during the first bolt is turned, the method for telescoping tube 31
Blue end 311 ensures to be connected all the time with the first bellows 32.Simultaneously, between the first bellows 32 and the 3rd bellows 35
It is also what is be fixedly connected.It is under compressive state and is assembled in conjunction with the 3rd bellows 35, such 3rd bellows 35
The first bellows 32, one of movement one end distance of telescoping tube 31 and 33 and second bellows of excessive ring flange 34 will be promoted.
Accordingly, it should be understood that, the 3rd bellows 35 will be connected with the first pipeline 10.Then, people can drive stay bolt, and profit
Cut off with the second end 332 of excessive ring flange 33 with the flange collar 313 on the pipeline end 312 of telescoping tube 31 in the second pipeline 20
The path that enters in the first bellows 32 of medium, such first pipeline 10, the 3rd bellows 35, telescoping tube 31 and second are managed
Road 20 is interconnected, that is, realizes and offset the first pipeline 10 with the 3rd bellows 35 come the first instead preceding bellows 32
The telescopic shape change produced with the second pipeline 20 because expanding with heat and contract with cold.And then realize do not stopping medium transmission while use,
And then the loss for avoiding enterprise's stopping production maintenance and causing.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements done etc. all should be included within the scope of protection of the invention.
