Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A direction view of Fig. 1.
In figure, each list of reference numerals is: 1, first end adapter, the 2, first bellows, 3, middle adapter, 4, the second bellows, the 5, second pipe nipple, 6, greatly pull bar, 7, elbow connection pipe, 8, elbow supporting plate, 8-1, curved support face, 9, riser, 9-1, brace groove, 10, strengthen gusset, 11, elbow, 12, spring support, 12-1, bearing mounting plate, 13, pull bar dunnage, 14, ring flat-plate.
Embodiment
Referring to Fig. 1, Fig. 2, the present invention is the orthogonal combined type expansion joints of a kind of import and export.Described combined type expansion joint comprises compound drag bar compensator, elbow connection pipe 7, elbow 11, spring support 12 and riser 9.Compound drag bar compensator, elbow connection pipe, elbow connect successively.Compound drag bar compensator comprises first end adapter 1, first bellows 2, middle adapter 3, second bellows 4, second pipe nipple 5 that connect successively, and medium is taken over by first end and flowed to the second pipe nipple, and the cross section of compound drag bar compensator is circular.Compound drag bar compensator is also provided with several large pull bar 6, different from the large pull bar of common compound drag bar compensator, and large pull bar of the present invention adds and grows to elbow 11 place.The affixed elbow connection pipe of second pipe nipple 7, Fig. 1, elbow embodiment illustrated in fig. 2 are rectangular cross-section, and elbow connection pipe is circular import rectangular outlet.If the sectional shape of elbow is circular cross-section, and the diameter of elbow and the second pipe nipple diameter inconsistent, then elbow' is the circular cross-section of variable diameters.
Still referring to Fig. 1, Fig. 2, described riser 9 is critical components of the present invention, the bottom of riser is fixed on spring support 12 top, riser top is provided with brace groove 9-1, the shape of brace groove and the form fit of elbow, can by elbow Matching installation in brace groove, thus by riser, the midfoot support of elbow is spacing.One end of each large pull bar 6 is connected through Ball faced nut and spherical washer with the ring flat-plate 14 being fixed on first end adapter 1 place, and the other end of each large pull bar is connected through Ball faced nut and spherical washer with riser.Visible, riser, both as the dunnage of elbow, plays position-limiting action while support elbow; Be again the connecting plate between spring support and elbow, through the vertical motion of spring support buffer bent, improve the operation stability of combined type expansion joint; The connecting plate of riser or large pull bar.Riser collection three functions are all over the body, realize many-sided effect with simple compact structure.Be provided with bottom spring support for installing fixing bearing mounting plate 12-1.For improving the support strength of riser, being provided with on riser top and strengthening gusset 10.
Still referring to Fig. 1, Fig. 2, set up elbow supporting plate 8, the setting orthogonal with riser of elbow supporting plate, is fixed on spring support top bottom elbow supporting plate, and elbow supporting plate top is provided with and curved support face 8-1, and curved support face coupling supports the large arc shaped surface outside elbow.Elbow supporting plate and riser synergy, by elbow secure support in orthogonal both direction, also play reinforcement supporting effect to riser simultaneously.
Referring to Fig. 1, the large pull bar 6 of illustrated embodiment arranges four.Because the length dimension of large pull bar is larger, for ensure large pull bar stability, prevent from work, producing larger distortion, set up pull bar dunnage 13, the corresponding large pull bar of each pull bar dunnage, each pull bar dunnage is fixed on the second pipe nipple 5, each pull bar dunnage is provided with tie rod hole, and each large pull bar passes respectively from the tie rod hole of each pull bar dunnage, forms support by the middle part of pull bar dunnage to large pull bar.
The present invention, for small space " L " type pipeline, receives satisfied using effect.
