Abstract
The utility model provides an universal hinge chain flexbleJoint, includes two end pipes and connects the bellows between the pipe of both ends, be equipped with corresponding otic placode on the outside of tubes wall of both ends respectively, the otic placode of double -phase correspondence passes through nut assembly pull rod, be equipped with corresponding hinge body fixing base on the outside of tubes wall of both ends respectively, the inboard of each hinge body fixing base is equipped with the outside hinge body of compriseing company's board of a pair of parallel respectively, is equipped with the middle hinge body of compriseing company's board of a pair of parallel between the outside hinge body of double -phase correspondence, and the middle hinge body connects through cross round pin axle and corresponding outside hinge body hinge respectively. The bellows inboard is equipped with the draft tube, draft tube one end and one end union coupling, and the draft tube other end is equipped with manages the complex sealing washer with the other end. The utility model discloses can satisfy the job requirement of the big compensation of high tensile, shear strength and multi -angle volume, the bellows of having solved present universal hinge chain flexbleJoint receives inside medium corruption of pipeline and dust and debris to influence the problem that leads to the fact too early damage.
Description
Technical field
The utility model relates to pipe line compensating device, is specifically related to a kind of universal coupling FlexbleJoint.
Background technique
The linkage of the universal coupling FlexbleJoint of prior art, is formed by a cardo ring with by two hinge plates of pinned connection on this cardo ring, and this kind of universal coupling FlexbleJoint can not meet high tensile, shearing strength and the job requirement of large compensation amount.In addition, bellows affects by the corrosion of pipeline interior media and dust and foreign material and causes damage, is also the main cause affecting existing universal coupling FlexbleJoint operating life.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of universal coupling FlexbleJoint that can meet the multidirectional flexibility job requirement of high tensile, shearing strength and large compensation amount and offset angle.
The bellows that the purpose of this utility model is also to solve existing universal coupling FlexbleJoint affects by the corrosion of pipeline interior media and dust and foreign material the problem causing premature breakdown.
Technical solution of the present utility model is: a kind of universal coupling FlexbleJoint, comprises two end pipes and is connected to the bellows between described two end pipes; The outer wall of described two end pipes is respectively equipped with the corresponding otic placode in position, and two corresponding otic placodes assemble pull bar by nut; The outer wall of described two end pipes is respectively equipped with the corresponding hinge body fixed base in position, the outside hinge body be made up of pair of parallel connecting plate is respectively equipped with in the inner side of each hinge body fixed base, be provided with the middle hinge body be made up of pair of parallel connecting plate between two corresponding outside hinge bodies, the two ends of this middle hinge body are hinged with corresponding outside hinge body respectively by cross bearing pin.
The technical solution of the utility model also comprises: in described bellows, be provided with guide shell, and one end of this guide shell holds one of pipe to hold pipe to be connected with described two, and the other end of this guide shell is provided with the dust ring holding the other end pipe of pipe to coordinate with described two.
The utility model is compared with the universal coupling FlexbleJoint of prior art, and compensation rate is large, and bearing capacity is strong, tension and shearing strength high, and offset angle is flexibly multidirectional.High tensile, shearing strength and the job requirement of large compensation amount can be met.The utility model is lightweight, easy for installation; Volume is little, and the place being suitable for limited space is installed.
The utility model can stop pipe interior medium to contact with bellows and dust and foreign material are stacked into bellows interior, causes bellows premature breakdown, thus effectively improves the operating life of universal coupling FlexbleJoint.
Accompanying drawing explanation
Fig. 1 is this universal coupling FlexbleJoint schematic diagram.
Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described.
As Fig. 1, this universal coupling FlexbleJoint comprises two end pipes 1 and bellows 2, two the end pipe 1 be connected between two end pipes 1 is placed in the left and right sides respectively, is connected with bellows 2 by welding.The outer wall of two end pipes 1 is respectively equipped with the corresponding otic placode 3 of the corresponding otic placode in position 3, two by welding and assembles pull bar 5 by two pairs of nuts 4, form the drag link mechanism of connection two end pipe.The outer wall of two end pipes 1 is respectively equipped with the corresponding hinge body fixed base 6 in position by welding, be respectively equipped with by welding the outside hinge body 7 be made up of pair of parallel connecting plate in the inner side of each hinge body fixed base 6, be provided with the middle hinge body 8 be made up of pair of parallel connecting plate between two corresponding outside hinge bodies 7, the two ends of this middle hinge body 8 are hinged with corresponding outside hinge body 7 respectively by cross bearing pin 9.Above-mentioned hinge body fixed base 6, outside hinge body 7, middle hinge body 8 are connected the universal joint of two ends pipe 1 with cross bearing pin 9 composition.Be provided with guide shell 10 in bellows 2, the left-hand end of this guide shell 10 is welded with the end pipe 1 in left side, is nested with a dust ring 11 outside the right-hand end of this guide shell 10, and this dust ring 11 coordinates with the aperture surface of the end pipe 1 on right side.Dust ring 11 adopts high temperature resistant, the corrosion resistant metal ring of circular cross-section, is fixed by welding in the port, outside of guide shell 10.
As Fig. 1, the drag link mechanism of this universal coupling FlexbleJoint and universal joint distinguish uniform four groups along the circumference of compensator.
