Abstract
The utility model provides a pressure balance universal hinge type corrugated compensator for a straight pipe, belonging to the field of a corrugated compensation device used for a pipeline. Two working corrugated pipes (2) are coaxially and symmetrically arranged at the left side and the right side of a balance corrugated pipe (1); the universal hinge corrugated compensator takes each working corrugated pipe (2) as a core; a short hinge plate (8) of a pair of pin shafts (7) is welded on an external connecting pipe (9) of the working corrugated pipes (2) by an external vertical plate (10); a long hinge plate (11) of another pair of pin shafts (7) spans the balance corrugated pipe (1) and is welded together with a corresponding internal connecting pipe (3); the short hinge plates (8) and the long hinge plates (11) of the two universal corrugated compensators are arranged oppositely to each other; the original pulling rod is replaced by the hinge plates; the compensator has dual-functions of absorbing the transverse displacement in the pipeline in any directions and absorbing the axial displacement in the pipeline; the pressure and the thrust are borne by the compensator; therefore, the pressure balance universal hinge type corrugated compensator has the advantages of small occupied space, convenience for application, few consumed material, low cost and convenience for installation and maintenance.
Description
Technical field
The utility model belongs to the ripple compensation apparatus field that pipeline is used, and relates to straight pipe pressure-equalizing universal coupling formula FlexbleJoint.
Background technique
In the prior art, the universal coupling FlexbleJoint can absorb the angular displacement on any direction, and two are used in combination, and then can absorb the lateral displacement on any direction in the pipeline; Straight tube pull-rod type pressure balance compensator is used for absorbing the axial displacement of pipeline, absorbs displacement amount by bellows in the work, the thrust that pull bar then bears pressure and produced; Deficiency is that when being used in combination by two universal coupling FlexbleJoints and straight tube pull-rod type pressure balance compensator three table apparatus, often because of the position that takes up room is restricted greatly, and three table apparatus consumptive materials are many, the cost height.
Summary of the invention
The technical problem that solves:
Two universal coupling FlexbleJoints and a straight tube pull-rod type pressure balance compensator are combined into one, dual-use, can absorb the lateral displacement on any direction, can absorb axial displacement again, can overcome the deficiencies in the prior art, little, the convenient application that not only take up room, and consumptive material is few, cost is low, and be beneficial to installation and maintenance.
The technological scheme that adopts:
Straight pipe pressure-equalizing universal coupling formula FlexbleJoint, it is the combination of two universal coupling formula FlexbleJoints and a straight tube pull-rod type pressure balance compensator, it is characterized in that: coaxial and two work bellowss of bilateral symmetry formula laying with the balance bellows, and link together by the inner connecting tube and the balance bellows of correspondence, the left and right port of balance bellows is welded to connect respectively after the tube, welds together by end ring plate and inner connecting tube; Be that core is laid the universal coupling FlexbleJoint with each work bellows respectively, concrete structure is, uniform four bearing pins of symmetric type on the same radial cross section of the cardo ring on the outer casing of work bellows, on two orthogonal diameter lines of cardo ring a pair of bearing pin is arranged respectively, wherein the short hinge plate of a pair of bearing pin welds together with the outer vertical plate that is welded on the externally connected pipe of work bellows, another band andgudgeon carrier bar to bearing pin axially strides across after the balance bellows, weld together with the inner vertical plate of being close to the end ring plate and be welded on the corresponding inner connecting tube, the alternate relative formula of short hinge plate in two universal coupling FlexbleJoints and band andgudgeon carrier bar is laid.
Beneficial effect:
Straight pipe pressure-equalizing universal coupling formula FlexbleJoint, owing to have the structure of two universal coupling FlexbleJoints forming by two work bellowss, therefore, can absorb the lateral displacement on any direction in the pipeline, simultaneously, owing to have the structure of the straight tube pull-rod type pressure balance compensator of forming by two work bellowss and balance bellows, wherein hinge plate has substituted pull bar, therefore, also can absorb the axial displacement in the pipeline, the thrust that pull bar then bears pressure and produced; Dual-use, little, the convenient application not only takes up room, pressure thrust is born by compensator self, the pipeline fixed support only needs to consider rigidity power and frictional resistance, be particularly useful for to be provided with in upright pipeline in the support bracket fastened high thing of high thrust position or the big inch line and use, and consumptive material is few, cost is low, is beneficial to installation and maintenance.

Further explanation in detail in conjunction with the accompanying drawings;
As shown in Figure 1, lay two work bellowss 2 with balance bellows 1 coaxial and left and right symmetric type, and the inner connecting tube by correspondence 3 links together with balance bellows 1, the left and right port of balance bellows 1 is welded to connect respectively after the tube 4, welds together by end ring plate 5 and inner connecting tube 3; Be that core is laid the universal coupling FlexbleJoint with each work bellows 2 respectively, concrete structure is, uniform four bearing pins 7 of symmetric type on the same radial cross section of the cardo ring 6 on the outer casing of work bellows 2, on two orthogonal diameter lines of cardo ring 6 a pair of bearing pin 7 is arranged respectively, the short hinge plate 8 of wherein a pair of bearing pin 7 welds together with outer vertical plate 10 on the externally connected pipe 9 that is welded on work bellows 2, another band andgudgeon carrier bar 11 to bearing pin 7 axially strides across after the balance bellows 1, weld together with the inner vertical plate 12 of being close to end ring plate 5 and be welded on the corresponding inner connecting tube 3, short hinge plate 8 in two universal coupling FlexbleJoints and band andgudgeon carrier bar 11 alternate relative formulas are laid.
