The diversion pipe of radial force is supportted, limit short tube one end is connected with bellows-welding, and the other end is equipped with the short pipe method for fixed limit
Orchid is connected between two short tube flanges by short tube flange bolt, is connected between two main flanges by elongated bolt, flange
Step is equipped in gland, and a step high position is bonded with sealing pipe surface, step low level is bonded with limit short tube surface, and rubber is close
Seal is located at step corner, and flange gland tightly fits in limit short tube free end outer wall by clamping screw, and by with
The sealing between two limit short tubes is realized in the cooperation of seal pipe and rubber seal, and two flange glands are tight by gland bolt
Solid phase connects.
Further, short tube flange top is equipped with limit hole, and elongated bolt passes through limit hole.
Further, limit hole, flange gland bolt, short tube flange bolt and elongated bolt are respectively at least provided with phase
Symmetrical two groups.
Further, short tube flange bolt and elongated bolt are equipped with nut at its maximal dilation displacement and are locked.
Compared with prior art, the utility model has the following beneficial effects:
1. the utility model use bi-bellow and limit short tube Combination Design, be equivalent to have three can be axial
The cluster tool of displacement considerably increases the compensation rate of pipeline.
2. the bi-bellow of the utility model design has the advantages that elasticity is good, rigidity is small, can effectively come dilatation
Axial direction that absorption line is generated by the reasons such as expand with heat and contract with cold, size side radially and angularly, the multi-faceted heat for reducing pipeline
Stress effectively protects pipeline, extends the service life of pipeline.
3. the utility model bellows interior is equipped with diversion pipe, when the internal force of medium or excessive external force, diversion pipe is effective
Absorb the displacement of bellows radial direction, to reduce bellows radial direction thermal stress, effectively protect the use of bellows
Service life.
4. the utility model flange gland bolt, short tube flange bolt and elongated bolt are set at its maximal dilation displacement
There is nut to be locked, prevents the utility model device to be more than maximum displacement and damage, effectively protect equipment.

Specific embodiment
The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, and the mode of the utility model includes
But it is not limited only to following embodiment.
A kind of multidimensional compensating joint of pipeline, including symmetrically arranged columned two parts, each section include successively connecting
Main flange 7, bellows 1, limit short tube 6 and the flange gland 2 connect, two parts are connected and sealed by seal pipe 3, and close
It is furnished with the rubber seal for sealing in 3 both ends of tube sealing.
The diversion pipe 5 for being used to support radial force is equipped with inside bellows 6, diversion pipe 5 effectively absorbs radial force, to ripple
Pipe 1 plays a very good protection.
Limit 6 one end of short tube is weldingly connected with bellows 1, and the other end, which is equipped with, is used for the fixed short tube flange 4 limited, and two
It is connected between short tube flange 4 by short tube flange bolt 9, and flange bolt 9 is equipped with spiral shell at limit 6 maximal dilation displacement of short tube
Mother locks, it is therefore prevented that limit short tube 6 is damaged beyond maximum displacement.
Be connected between two main flanges 7 by elongated bolt 10, be equipped with step in flange gland 2, and a step high position with
The fitting of 3 surface of seal pipe, step low level is bonded with limit 6 surface of short tube, and rubber seal is located at step corner, flange pressure
Lid 2 tightly fits in limit 6 free end outer wall of short tube by clamping screw, and flange gland 2 can be moved axially relative to limit short tube 6
It is dynamic, realize that the sealed connection between two limit short tubes 2 is realized in the compensation of axial displacement, the cooperation of flange gland 2 and seal pipe 3.
4 top of short tube flange be equipped with limit hole 11, elongated bolt pass through limit hole 11, and elongated bolt compensating joint most
It is equipped with nut at big displacement to be locked, effectively prevents compensating joint and is damaged beyond maximum displacement, meanwhile, elongated bolt
10 it is at least symmetrical be provided with two groups, compensating joint radial shear power can be absorbed, effective protection compensating joint is due to by strong
Big shearing force and damage failure.
Axial displacement is the elongation or decrement in liquid flow direction, and wherein the bellows on equipment both sides has bullet
The advantage that property is good, rigidity is small, effective dilatation carry out the axial, transverse direction and angle that absorption line is generated by the reasons such as expanding with heat and contract with cold
To change in size, bellows interior be equipped with diversion pipe, when the self-excitation phenomena (internal force) of medium is excessive or external force is excessive, water conservancy diversion
Cylinder largely absorbs radial thermal stress, prevents the damage of bellows, to protect equipment, limits short tube in maximum
At stroke, with nut locking size, when encounter expand with heat and contract with cold, geology differential settlement and need certain displacement, at this time
Flange gland free extension in the range of its permission compensates axial displacement.Elongated screw rod links together whole equipment, leads to
Nut on long bolt is locked at maximum displacement, to realize the free extension of equipment and effectively prevent equipment beyond dominant bit
It moves and damages.The utility model compares pervious single compensation equipment, is equivalent to three equipment now, axial displacement is exactly three
A set greatly increases the displacement of compensation.
Above-described embodiment is only one of preferred embodiments of the present invention, should not be taken to limit the utility model
Protection scope, as long as the utility model body design thought and mentally make have no the change of essential meaning or profit
Color, it is solved the technical issues of it is still consistent with the utility model, the protection scope of the utility model should all be included in
