Description
Technical field
The invention belongs to flexible pipe field, particularly relate to a kind of Telescopic flexible pipe and its application.
Background technology
Flexible pipe of the prior art is flexible is all that tube body itself makes fold or multistage folded state realizes,
The corrugations structure that i.e. tube wall of its Telescopic flexible pipe is typically coiled by the length direction around described Telescopic flexible pipe
Become.Such Telescopic flexible pipe its when body is stretched or in body, hydraulic pressure is bigger, flexible pipe can extend automatically,
But the flexible pipe after Shen Chang wants manual compression to go back, therefore cause existing this flexible pipe range of application wideless,
A lot of fields cannot use.In addition, existing Telescopic flexible pipe is the thinnest at bending part, and manages
Body itself does not have elasticity, and flexible number of times is very limited.
Summary of the invention
It is scalable soft that the goal of the invention of the present invention is to provide a kind of can increasing with hydraulic pressure and automatically extend
Pipe, this Telescopic flexible pipe applied range, durability is good.
In order to realize foregoing invention purpose, present invention employs techniques below scheme:
Telescopic flexible pipe, by multiple tube units joint continuously, be sequentially connected with and form；Described each tube unit
Joint includes that tubulose our department and one can the bending rebate of elastic bending；Described tubulose our department one end external diameter is big
In the other end, the outside of its other end is provided with the annular protrusion projected radially outward, and described annular protrusion is embedded
Equipped with an annular permanent magnet；Described can one end and described tubulose our department another of bending rebate of elastic bending
One end is connected as a single entity；Described can the other end pipe described with the adjacent next one of bending rebate of elastic bending
One end of shape our department is connected as a single entity；Described the middle part of bending rebate of elastic bending can be provided with one with annular forever
The steel loop that magnet is attracting；Described annular protrusion is an annular burnishing surface near the one side of bending rebate, phase
Instead, the one side away from bending rebate is an annular slope；Described bending rebate cross section on one side in
Inverted S-shaped；Described steel loop position is fixed on the bending part in the middle part of bending rebate；When bending rebate bending
Time, the position of described steel loop is corresponding with described annular permanent magnet position, and steel loop is attracted by annular permanent magnet,
Bending rebate bending part is just against on the annular burnishing surface of above-mentioned annular protrusion by this steel loop.
As preferably, described tubulose our department is made up of elastomeric material, and described bending rebate is by silica gel material system
Become.
Present invention Telescopic flexible pipe based on above-mentioned performance, another purpose is offer one, and this is scalable soft
Pipe alternative applications in the flexible pipe of hydrocarbon exploration and production application.
In order to realize foregoing invention purpose, present invention employs techniques below scheme:
A kind of above-mentioned Telescopic flexible pipe is carrying compressed-air actuated earthquake gun hose, for transmitting landwaste and brill
The drilling well flexible pipe of well liquid and should for what compression fluid and instrument were delivered in the flexible pipe of subsurface environment
With.
Compared with prior art, have employed the Telescopic flexible pipe of technique scheme, this flexible pipe is by tubulose originally
One end, portion is provided with the annular protrusion of embedded annular permanent magnet, then by being provided with one in the middle part of bending rebate with annular
The steel loop that permanent magnet is attracting, when bending rebate bending, due to the attraction of magnet so that bending is roundabout
Portion is constantly in bending state.Until hydraulic pressure is more than a threshold value, overcome the suction between steel loop and annular permanent magnet
Gravitation also promotes bending rebate elasticity to stretch.Therefore, this Telescopic flexible pipe compared with existing flexible pipe, its
Can strengthen with hydraulic pressure and automatically extend, self stretch because it relies on permanent magnet nature to maintain, Wu Xutong
Crossing flexible pipe self and make fold shape, therefore its resistance to compression, flexible number of times and durability are fine, have widely
Range of application.
Accompanying drawing explanation
The cross-sectional view of Fig. 1: the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further.
Embodiment: Telescopic flexible pipe as shown in Figure 1, this Telescopic flexible pipe by multiple tube units joint continuously,
It is sequentially connected with composition.Wherein, each described tube unit joint includes that a tubulose our department 1 and one can elastic roll over
Curved bending rebate 3.Tubulose our department 1 is made up of elastomeric material, and bending rebate 3 is made up of silica gel material.
See as it is shown in figure 1, above described tubular our department one end 1a external diameter is more than other end 1b, its other end 1b
Outside be provided with the annular protrusion 2 projected radially outward, be embedded with an annular permanent magnet 21 in annular protrusion 2.
Above-mentioned can one end of bending rebate 3 of elastic bending be connected as a single entity with the other end 1b of tubulose our department 1；Can
One end 1a company of other end tubulose described with adjacent next one our department 1 of the bending rebate 3 of elastic bending
It is integrated.The middle part of bending rebate 3 of elastic bending can be provided with a steel loop attracting with annular permanent magnet 21
31.When bending rebate 3 bending, the position of steel loop 31 is corresponding with annular permanent magnet 21 position and can phase
Attract.
Above-mentioned annular protrusion 2 be side cross section be the protuberance of similar triangle, wherein annular protrusion 2 is close
The one side of bending rebate 3 is an annular burnishing surface, and the one side away from bending rebate 3 is a circular slanting
Face.Above-mentioned bending rebate 3 side cross section is inverted S-shaped, the bending part position in the middle part of bending rebate 3
Putting and be fixed with above-mentioned steel loop 31, when bending rebate 3 bending, steel loop 31 is inhaled by annular permanent magnet 21
Drawing, bending rebate 3 bending part is just against by this steel loop 31 on the annular burnishing surface of above-mentioned annular protrusion 2.
During use, when Telescopic flexible pipe intraluminal fluid pressure is increased dramatically, more than a threshold value, the flexible pipe on this flexible pipe
Unit joint will save land elongation by a joint one, often elongation one joint, will increase pipe inner volume and be increased dramatically to balance
Pressure.
In the present invention, the material of above described tubular our department 1 and bending rebate 3 not chooses at random, its choosing
Select tubulose our department 1 and select the most durable rubber of price, and bending rebate 3 uses silica gel, it
So so, it is because the bending rebate 3 that silica gel makes and can be connected as a single entity with rubber in the fabrication process,
And the bending rebate 3 that silica gel is made is after repeatedly folding, and elasticity, antifatigue, durability are the most very
Good.
Therefore, the Telescopic flexible pipe of the present invention can apply to easily produce High Pressure Difference and burst flexible pipe application
In environment, such as hydrocarbon exploration and the flexible pipe of production application.Specifically, including for carrying compression sky
The earthquake gun hose of gas, for transmitting the drilling well flexible pipe of landwaste and drilling fluid and even for fluid will be compressed
With the flexible pipe that instrument is delivered to subsurface environment.In these specific areas, its dependence is more than with intraluminal fluid pressure
One threshold value and extending is avoided causing explosion due to the High Pressure Difference of process, and using effect is the best.
