Description
Technical field
The utility model relates to compensator, particularly relates to a kind of pipeline one-off compensator.
Background technique
Disposable FlexbleJoint is generally used in heat distribution pipeline, substantially identical with external pressure compensator principle, but it is after cold conditions is installed, enter, by construction requirement, whole pipe network or part pipe network are carried out preheating, when the tube wall temperature of whole pipe network reaches preheating temperature, the outer of expansion joint is enclosed within lap-joint's secondary welding, whole compensator is welded into one, whole piping is fixed thereupon, no longer includes compensating action.
At present, the compensator of prior art is all adopt bellows to carry out the compensation device of extending amount, there is bellows far apart relative to the thickness of tube wall, when in the face of High Temperature High Pressure, impact for bellows is very large, although only use once when being preheating, but once occur leaking, will all lose efficacy for a whole set of compensator, obstruction is brought to pipeline commencement of commercial operation, and the mode of bellow-type expansion, compensation rate is also subject to the restriction designing wave number, and can only to nose balance, less rotation compensation cannot be accomplished, the rotation stress of the generation after field pipes preheating cannot be eliminated, in view of these problems, my unit have developed the technical solution of the utility model.
Summary of the invention
The utility model overcomes shortcoming of the prior art, provides a kind of pipeline one-off compensator.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of pipeline one-off compensator, comprise telescopic pipe and fixed tube, described telescopic pipe inserts fixed tube, toroidal cavity is formed between described telescopic pipe and fixed tube, described toroidal cavity vertically ecto-entad is provided with trim ring successively, back-up ring and anticreep limit stoper, described trim ring and back-up ring are all fixedly connected on fixed tube and are slidably connected to telescopic pipe, described trim ring, back-up ring, sealed cavity is formed between fixed tube and telescopic pipe, sealing material is provided with in described sealed cavity, described anticreep limit stoper is fixedly connected on telescopic pipe.
As preferably, described compensator also comprises material injecting device, and described material injecting device is arranged in fixed tube, and described material injecting device is connected with sealed cavity.
As preferably, described compensator also comprises reducer pipe, and described reducer pipe one end is connected to fixed tube, and the diameter of the other end equals the diameter of telescopic pipe.
As preferably, described anticreep limit stoper is limited ring.
As preferably, described limited ring external diameter is less than the internal diameter at least 1cm of fixed tube.
As preferably, described anticreep limit stoper is limiting stopper.
As preferably, described compensator also comprises stiffening rib, and described stiffening rib one end is fixedly connected on fixed tube, and the other end is slidably connected to telescopic pipe.
As preferably, described sealing material is Expanded graphite.
Compared with prior art, the utility model has the advantages that: compensator pipe thickness can be consistent with pipeline wall thickness, sealing configuration adopts graphite grazing, there is the ability of excellent high temperature resistance high pressure, the demand of all kinds of pressure piping can be met, the Applicable scope of compensator is further expanded, and safety is further promoted; And compensation rate because of non-ripple pipe mechanism without wave number impact, can free adjustment, there is no the potential risk of stretching; When there is rotation stress when pipeline preheating, also can realize rotation compensation, eliminate the rotation stress of pipeline.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of pipeline one-off compensator, comprise telescopic pipe 1 and fixed tube 8, described telescopic pipe 1 inserts fixed tube 8, toroidal cavity is formed between described telescopic pipe 1 and fixed tube 8, described toroidal cavity vertically ecto-entad is provided with trim ring 3, back-up ring 6 and limited ring 7 successively, described trim ring 3 and back-up ring 6 are all fixedly connected on fixed tube 8 and are slidably connected to telescopic pipe 1, described trim ring 3, back-up ring 6, between fixed tube 8 and telescopic pipe 1, form sealed cavity, be provided with Expanded graphite 5 in described sealed cavity, described limited ring 7 is fixedly connected on telescopic pipe 1.Described compensator also comprises material injecting device 4, and described material injecting device 4 is arranged in fixed tube 8, and described material injecting device 4 is connected with sealed cavity.Described compensator also comprises reducer pipe 9, and described reducer pipe 9 one end is connected to fixed tube 8, and the diameter of the other end equals the diameter of telescopic pipe 1.Described limited ring 7 external diameter is less than the internal diameter 1.2cm of fixed tube 8.Described compensator also comprises stiffening rib 2, and described stiffening rib 2 one end is fixedly connected on fixed tube 8, and the other end is slidably connected to telescopic pipe 1.
When the utility model uses, telescopic pipe 1 and reducer pipe 9 are all welded in field pipes, job site supplements the Expanded graphite 5 of certain pressure in described sealed cavity by material injecting device 4, after the complete free expansion of pipeline preheating, by trim ring 3 girth welding in telescopic pipe 1, stiffening rib 2 is welded in telescopic pipe, namely completes the installation of one-off compensator, debugging can formally drop into pipeline actual motion.Obviously, limited ring 7 plays the anti-slip effect of telescopic pipe 1 in one-off compensator transport and installation process.Because compensator pipe thickness can be consistent with pipeline wall thickness, the sealed cavity of compensator adopts Expanded graphite to fill, there is the ability of excellent high temperature resistance high pressure, the demand of all kinds of pressure piping can be met, the Applicable scope of one-off compensator is further expanded, safety is further promoted, and one-off compensator is not owing to having bellows mechanism, can free adjustment, there is no the potential risk of stretching, when there is rotation stress when pipeline preheating, also can realize rotation compensation, eliminate the rotation stress of pipeline.
Except the above embodiments, other mode of executions do not stated also should within protection domain of the present utility model.Specific embodiment as herein described is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.Although be described through specific term herein, but do not get rid of the possibility using other terms, use these terms to be only used to describe and explain essence of the present utility model easily, the restriction that they are construed to any one additional is all contrary with the utility model spirit.
