Abstract
An expansion device capable of providing displacement compensation to a pipeline achieves an excellent double-seal effect through utilizing double-seal washers on left-right symmetrical similar wedge-shaped pipeline annual bases, allows left and right side pipelines to achieve linear displacement compensation through utilizing a limiting sleeve structure which is formed by four half round limiting sheets and a cylindrical lantern ring through 48 standard hexagon bolts, and allows the left and right side pipelines to keep a certain angle displacement through utilizing an included angle between the upper surfaces of the left-right symmetrical similar wedge-shaped pipeline annual bases and the end surface of the cylindrical lantern ring.
Description
Technical field: the utility model relates to a kind of expansion device that bit shift compensation is provided
Background technique:
At present, because the general metal corrugation compensator that adopts when needing bit shift compensation at present, the type metal corrugation compensator utilizes telescopic design, takies a large amount of spaces and because own wt when causing the numerous suspension and support of needs installation greatly.Metal corrugation compensator can provide a certain amount of bit shift compensation amount really in engineering application, but often since metal corrugation compensator general what adopt is sleeve design, therefore limited the validity of compensation and the reliability of sealing greatly.
This expansion device has well solved the problems referred to above; Function with the little and double seal of volume; When satisfying piping displacement compensation, can be good at guaranteeing the sealing effect of pipeline, and have benefited from cleverly that a type wedge-shaped design makes later maintenance more convenient.
The model utility content:
The utility model solves the technological scheme that its technical problem adopted: utilize the double seal effect of double density seal, and utilize the special construction of dual type of wedge shape to allow pipeline that bigger linear displacement and angular displacement is provided.
The utility model relates to a kind of expansion device that bit shift compensation is provided, and it is characterized in that the compensator front is fixed in semicircle banking stop 1, semicircle banking stop 2 on the cylindrical collar 7 by the evenly distributed back of 24 standard hex bolts respectively; The compensator two ends are symplex structure, and semicircle banking stop 3, semicircle banking stop 4 evenly are fixed on the cylindrical collar 7 through other 24 standard hex bolts; Include class wedge shape pipeline circular base 5, type wedge shape pipeline circular base 6 of symmetry about receiving in the cylindrical collar of four banking stop constraints, this ring pedestal is fixed on the pipeline outer wall that bit shift compensation need be provided through welding procedure; The class wedge shape pipeline circular base that is positioned at cylindrical collar is a wedge-shaped structure, wherein comprises two grooves that hold seal washer; Article two, in seal washer type of the being placed in wedge shape pipeline circular base, this compensator comprises four seal washers altogether, is symmetrically arranged in respectively in the groove of class wedge shape pipeline circular base of both sides.
Description of drawings:
Further set forth below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4,5 pairs of these expansion devices of accompanying drawing.
Description of drawings
Accompanying drawing 1 compensator front view
Accompanying drawing 2 compensator side views
The dual washer sealing schematic representation of accompanying drawing 3 compensators
Accompanying drawing 4 compensator linear displacement schematic representation
Accompanying drawing 5 compensator angular displacement schematic representation
1,2,3,4 is semicircle banking stop among the figure; Two-sided totally four ten eight standard hex bolts of 8 representatives; 5,6 type of being wedge shape pipeline circular bases, 7 is cylindrical collar, adds up to four rubber gasket on A representative type of the being placed in wedge shape circular base.
Embodiment:
Shown in accompanying drawing 1, this compensator front is fixed in semicircle banking stop 1, semicircle banking stop 2 on the cylindrical collar 7 by the evenly distributed back of 24 standard hex bolts of 8 representatives respectively.Shown in accompanying drawing 2, the compensator two ends are symplex structure, and semicircle banking stop 3, semicircle banking stop 4 evenly are fixed on the cylindrical collar 7 through other 24 standard hex bolts.Shown in accompanying drawing 3; The class wedge shape pipeline circular base 5, type wedge shape pipeline circular base 6 that include symmetry about receiving in the cylindrical collar of four banking stop constraints; This ring pedestal is fixed on through welding procedure on the pipeline outer wall that bit shift compensation need be provided, and wherein plays dual seal action by four the rubber gasket of ading up on type of the being placed in wedge shape pipeline circular base of A representative.
Shown in accompanying drawing 3, the sealing principle of this expansion device is to utilize the symmetrical type of double-seal gasket on the wedge shape pipeline circular base to play good double seal effect.
Shown in accompanying drawing 4; The pipe line displacement principle that provides of this expansion device is that the spacing collar structure of utilizing four semicircle banking stops and cylindrical collar to form through 48 standard hex bolts allows left and right sides pipeline to realize the linear displacement compensation, and accompanying drawing 4 is depicted as pipeline when installing and allows the max line displacement amount that provides.
Shown in accompanying drawing 5, this expansion device provide pipeline angular displacement principle to be because symmetrical type wedge shape annular pedestal upper surface has certain included angle with cylindrical collar 7 end faces, a certain amount of angular displacement appears in permission left and right sides pipeline.
This expansion device has adopted cleverly, and a type wedge-shaped sleeve cartridge type design allows pipeline that bigger linear displacement compensation ability is arranged; And the design of type wedge shape pipeline circular base makes pipeline have the ability of certain angular displacement, linear displacement when satisfying the excellent sealing state to be implemented in and angular displacement compensation.
