Fig. 2 is the structural representation of telescoping tube 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, connecting line 100 provided by the present invention, including the first pipeline 10 are referred to, with respect to the first pipeline 10
The second pipeline 20 set, and for connecting the pipeline connection mechanism of the first pipeline 10 and the second pipeline 20.Wherein described
One pipeline 10 and any two part that the second pipeline 20 is connecting line 100, in practice, the first pipeline 10 and the second pipeline
20 caliber may be configured as equally, may be alternatively provided as the pipe of different the first pipeline 10 and the second pipeline 20 in the present embodiment
Footpath size 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, the ripple of counter flange disk 33 and second
Line pipe 34.The telescoping tube 31 is interconnected with the first pipeline 10 and the second pipeline 20, wherein the flange end of telescoping tube 31
311 are fixedly connected with the flange end 11 of the first pipeline 10, and the part of pipeline end 312 of telescoping tube 31 stretches to the second pipeline 20
It is interior, and internal diameter of the external diameter of pipeline end 312 less than second pipeline 10 of the telescoping tube 31.First bellows 32 and mistake
Cross ring flange 33 and be set in the outside of telescoping tube 31.
The flange end 311 of the telescoping tube 31, the first bellows 32, the flange end of the pipeline 20 of mounting flange 33 and second
21 are sequentially connected fixation.Wherein, the pipeline end 312 of the telescoping tube 31 is fixed with a flange collar at the position of mounting flange 33
313, the flange collar 313 is outwards fitted with mounting flange 33, and an elongated slot 314 is offered in the flange collar 313, for use as
Second pipeline 20 flows to the feed pathway of the first bellows 32；Correspondingly, the mounting flange 33 is between two flange ends
An auxiliary piping 331 outwards is communicated with pipeline section, is specifically the pipeline section for being assemblied in mounting flange 33 threadably
On.And the auxiliary piping 331 is equipped with a piston 333 by spring 332, and available piston 333 is to the flange collar 313 of telescoping tube 31
On elongated slot 314 obstructed, and then realize the path that the second pipeline 20 flows to the first bellows 32 obstructed.So
It is appreciated that the auxiliary piping 331 is assemblied at the position at the place of elongated slot 314 of the flange collar 313 of telescoping tube 31.
In the present embodiment, the height of the piston 333 is more than the height of the upper convex ring 313 of telescoping tube 31.So when
When being obstructed with piston 333 to the elongated slot 314 in flange collar 313, its part of piston 333 is still in auxiliary piping 331, so
When ensuring that piston 333 is obstructed to feed pathway, it, can effective manner quilt by the position-limiting action of auxiliary piping 331
The pressure that medium positioned at the outside of piston 333 is produced to piston 333.Further, the piston 333 is set to hollow-core construction,
A water injection hole (not shown) is offered thereon, and when piston 333 is assembled on auxiliary piping 331 by spring 332, the work
Water injection hole on plug 333 is arranged in auxiliary piping 331.
From the foregoing, it will be observed that when the first bellows 32 occurs to rupture and leak, pressure of the medium to piston 333 will be reduced,
The gravity of piston 333 can thus be broken, medium is to the pressure and spring 332 of piston 333 between the active force of piston 333
Balance, piston 333 declines therewith, so that the water injection hole on piston 333 exposes from auxiliary piping 331, correspondingly, positioned at convex
The medium enclosed in 313 elongated slots 314 will enter to piston 333 by water injection hole, and provide the gravity suffered by piston 333, with
Piston 333 in medium entrance, piston 333 is gradually reduced and finally realizes the barrier to elongated slot 314 in flange collar 313, so
It is achieved that the feed pathway for entering to the first bellows 32 to the second pipeline 20 is obstructed, i.e. by above-mentioned rational knot
Structure is set, and realizes the operation obstructed automatically.
Second bellows 34 is applied in the pipeline connection mechanism, is to be used to substitute when the Cracking Failure of the first bellows 32
The dilatation that the first pipeline 10 and the second pipeline 20 are produced because expanding with heat and contract with cold is offset with the second bellows 34 afterwards.Described
Two bellowss 34 are socketed on the first pipeline 10, wherein, one end of the 3rd bellows on the first pipeline 10 with fixing
Some flange plates 12 are fixedly connected, and the other end is fixedly connected with the first bellows 32.And when the second bellows 34 is assembled to
When on the first pipeline 10, the ripple of second bellows 34 is in tightening state.That is, the 3rd bellows 35 is to be in
It is assembled in the state of compression on pipeline 100.
In the present embodiment, second bellows 34 is provided in the outside at the upper flange end 311 of telescoping tube 31, and described
The flange end 11 of first pipeline 10, the flange end of the bellows 32 of flange end 311 and first of telescoping tube 31 offer multiple respectively
One-to-one screwed hole (not shown), and it is attached fixation with many first bolt (not shown).So the pipeline is connected
Mechanism is applied normally to be used on connecting line, and the first pipeline 10 and the second pipeline 20 can be offset with the first bellows 32 because of heat
Swollen shrinkage and the dilatation produced.And when the first bellows 32 ruptures, the first bolt can be turned, make the first pipeline 10
The flange end 311 of flange end 11 and telescoping tube 31 depart from, and the flange of the bellows 32 of flange end 311 and first of telescoping tube 31
End is fixedly connected, further, with annular array between the bellows 32 of flange end 311 and first of the telescoping tube 31
Second bolt (not shown) is attached fixation.To ensure people during the first bolt is turned, the flange of telescoping tube 31
End 311 ensures to be connected all the time with the first bellows 32.Simultaneously, between the first bellows 32 and the second bellows 34
It is fixedly connected.It is under compressive state and is assembled in conjunction with the second bellows 34, such second bellows 34 is just
The first bellows 32, one of movement one end distance of telescoping tube 31 and excessive ring flange 33 can be promoted.Accordingly, it should be understood that,
Second bellows 34 will be connected with the first pipeline 10.
To sum up, connecting line provided by the present invention, passes through rational structure setting so that the connecting line is when in use
It can be triggered with the flexible of the first bellows to offset the first pipeline with the second pipeline during pumped (conveying) medium because expanding with heat and contract with cold
Stroke, and when the first bellows ruptures, the flange end of telescoping tube and the flange end of the first pipeline can be unclamped, with
Second bellows uses to substitute the first bellows, is so achieved that while medium transmission is not stopped and uses, and then keeps away
The loss that the stopping production of Mian Liao enterprises is repaired and caused.
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.
