Description
Technical field
The utility model relates to a kind of expansion joint, especially for fully-balanced expansion joint, the genus pipe fitting technical field of T type pipeline in the reaction device process pipe systems such as petrochemical industry, iron and steel.
Background technique
The reaction device process pipe system of enterprise such as petrochemical industry, iron and steel is intricate, because of the pipe stress distortion needs to adopt corrugated expansion joint to be compensated usually.In corrugated expansion joint design standard and application practice, often based on the expansion joint compensating axial, laterally and hinge to three kinds of citation forms, these structural type expansion joints only can be distinguished straight pipeline, Z type pipeline and the L pipeline of compensate for process pipeline.Be divided into again as the balance expansion joint: be used for compensation and balance Z type, the ducted transverse stress universal type of L type; Be used for compensating straight tube balance type with the axial stress of balance straight pipeline; Be used to compensate and the hinge type of balance Z type and the ducted lateral pressure of L type and universal type etc.Also have a kind of curved tube balanced expansion joint that is used for compensating and transverse stress axial, but this expansion joint only is only applicable to the corner of L pipeline with balance L type pipeline.At present in the T type pipeline in pipeline stage casing, still do not have suitable equilibrium swelling selected parts usefulness, take usually to be used in combination, to compensate and equilibrium stress with longitudinal balance type and lateral balance type expansion joint, this mode that is used in combination, complex structure and reliability are relatively poor.
The model utility content
Technical problem to be solved in the utility model is: the fully-balanced expansion joint that provides a kind of T of being used for type pipeline, alternative longitudinal balance type and lateral balance type expansion joint to be used in combination.
The alleged problem of the utility model is solved by following technological scheme:
A kind of fully-balanced expansion joint, its specialization is: it comprises balance bellows, two work bellowss, two connecting tubes, two dunnages, two end plates, two cardo rings and main connecting plate, secondary connecting plate, the affixed successively end plate in described balance bellows both sides, work bellows, dunnage, connecting tube, described two cardo rings are ring set work bellows respectively; The end plate that described main connecting plate two ends will be positioned at balance bellows heteropleural is connected with a cardo ring, wherein with end plate be affixed, with cardo ring for being slidingly connected; The dunnage that described secondary connecting plate two ends will be positioned at balance bellows homonymy is connected with a cardo ring, wherein, with dunnage be affixed, with cardo ring for being slidingly connected.
Above-mentioned fully-balanced expansion joint, the volume of described two work bellowss is identical, and two work bellows volume sums equal the volume of balance bellows.
Above-mentioned fully-balanced expansion joint, described every pair of end plate that is connected is connected by the symmetrically arranged main connecting plate of two covers respectively with cardo ring, and each circumferential position that overlaps main connecting plate differs 90 °; Every pair of dunnage that is connected is connected by the symmetrically arranged secondary connecting plate of two covers respectively with cardo ring, and each overlaps secondary connecting plate circumferential position and differs 90 °.
The utility model still do not have suitable equilibrium swelling joint problem at T type pipeline in the process pipe system and specialized designs a kind of full equilibrium swelling joint, this expansion joint is the composite structure of universal coupling expansion joint and straight tube equilibrium swelling joint, be used in combination in order to axial balance type and lateral balance type expansion joint in the alternative present T type pipeline, realize Fully-balanced pressure balance and stress compensation T type pipeline.Test shows that the utility model meets design requirement fully, has compact structure, reliability height, takies characteristics such as the pipeline space position is little, convenient for installation and maintenance, saveall cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Label is expressed as follows in the accompanying drawing: 1. connecting tube; 2. dunnage; 3. work bellows; 4. cardo ring; 4-1; Slotted hole; 5. main connecting plate; 6. end plate; 7. balance bellows; 8. secondary connecting plate; 9. bearing pin.
Embodiment
Referring to Fig. 1, the utility model is constructed as follows: balance bellows 7 two-port in the middle of being positioned at are affixed end plate 6 respectively, two work bellowss 3 are affixed with end plate respectively, in the affixed dunnage 2 of the outside of two work bellowss port difference, affixed respectively two connecting tubes of two dunnages 1, two cardo ring 4 difference ring sets are outside the work bellows.One end plate that will be positioned at balance bellows heteropleural by the two ends of main connecting plate 5 is connected with a cardo ring, wherein main connecting plate and end plate be affixed, with cardo ring for being slidingly connected; The dunnage that described secondary connecting plate 8 two ends will be positioned at balance bellows homonymy is connected with a cardo ring, wherein, secondary connecting plate and dunnage be affixed, with cardo ring for being slidingly connected.Be slidingly connected through bearing pin 9 and slotted hole formation between major-minor connecting plate and the cardo ring.The volume of above-mentioned two work bellowss, two work bellows volume sums equal the volume of balance bellows.
Referring to Fig. 1, Fig. 2, every pair of end plate that is connected 6 is connected by the symmetrically arranged main connecting plate 5 of two covers respectively with cardo ring 4, as shown in the figure, its top of cardo ring that is positioned at balance bellows 7 left sides is provided with cover (two a) main connecting plate, its underpart is provided with cover (two a) main connecting plate; Its front portion of cardo ring that is positioned at balance bellows 7 right sides is provided with cover (two a) main connecting plate, its rear portion is provided with cover (two a) main connecting plate, and each circumferential position that overlaps main connecting plate differs 90 °.Equally, every pair of dunnage that is connected 2 is connected by the symmetrically arranged secondary connecting plate 8 of two covers respectively with cardo ring 4, and each overlaps secondary connecting plate circumferential position and differs 90 °.
When the utility model is used for T type pipeline, when pipeline produces axial stress and end thrust, full equilibrium swelling joint makes work bellows 3 produce axial compression by the major and minor connecting plate that is connected with end plate 6 that is provided with, compensate for process pipeline axial stress and end thrust make balance bellows 7 produce and the opposite stretch compensation of work bellows displacement simultaneously.Because balance ripple volume equals the volume sum of two work bellowss, therefore, full equilibrium swelling joint internal capacity does not change, thereby reaches the effect of longitudinal balance.When process pipe produces transverse stress and lateral thrust, full equilibrium swelling joint by the cardo ring 4 that is provided with is connected bearing pin 9 and produces horizontal the compensation.
