At present, the axialmode compensator that is used for extraction duct axial displacement mainly contains two kinds, promptly universal compensator and straight pipe pressure-equalizing type compensator.Though they can absorb axial displacement effectively, but still there is certain narrow limitation.As universal compensator for occasion, promptly pipeline position is lower, arrange well, main anchor is provided with when being easier to, its less expensive practicality often.But in other occasions, bigger as line pressure, then, the cost of main anchor is improved greatly because the interior pressure thrust that main anchor bears may be very big.In addition, in some high-altitudes, high pressure line, it is very difficult that main anchor is set, and sometimes or even impossible, at this moment universal compensator just can't meet design requirement.Existing another kind of compensator, i.e. straight pipe pressure-equalizing type compensator, it is linked together by load-carrying member and middle balance bellows by the work bellows at two ends, and wherein the useful area of balance bellows is the twice of work bellows.Though this compensator can solve the problem of pressing thrust in the extraction duct, main anchor needn't be set, but because the balance bellows useful area of this compensator is bigger, so volume is big, and its linkage structure makes compensation rate less, and rigidity is relatively large, and this requires the occasion that compensation rate is big, rigidity power is less just not too suitable for many.
The purpose of this utility model is exactly to provide a kind of guidance quality good in order to address the above problem, and compensation rate is big, and rigidity is less relatively and volume is little and need not to be provided with the bypass axial pressure balance type FlexbleJoint of main anchor.
Technical solution of the present utility model:
A kind of bypass axial pressure balance type FlexbleJoint, it includes work bellows and load-carrying member, it is characterized in that load-carrying member is connected with the balance bellows that equates of useful area of its useful area and work bellows, and link together by will the work two ends of bellows and the opposite ends of balance bellows of load-carrying member.
The utility model is decreased to the useful area of balance bellows identical with the bellows of working, and link together by will the work two ends of bellows and the opposite ends of balance bellows of load-carrying member, so it has overcome the deficiency of existing universal compensator and the existence of straight pipe pressure-equalizing type compensator, it is simple in structure, volume is little, cost is low, has good steering capability, compensation rate is big, and rigidity is less relatively, and need not to be provided with main anchor, use wide, can satisfy the pipeline designs requirement of various occasions, be particularly useful for the occasion that aerial pipeline or inconvenience are provided with main anchor, have broad application prospects.
