Abstract
The utility model relates to a profile expanding joint for a hot wind (dust) pipeline compensator. Because the expansion joint of an original ordinary compensator has larger size, the compensation requirement in the range of small size can not be satisfied. At present, two inner corrugated pipes 1 and 3 and two outer corrugated pipes 2 and 4 form the profile expanding joint. When the pipeline of the coupling compensator expands because of heat and shrinks because of cold, the angular displacement is produced by the corrugated pipes of both ends; the transverse misplacement can be achieved; the transverse movement of a pipeline can be compensated; the contradiction that the length of the space of the pipeline is insufficient can be solved. The profile expanding joint can be made into series specification device whose height (diameter) is from 0.3 m to 7 m according to the requirement; a new device is added to the class of pipeline compensators.
Description
The utility model relates to a kind of hot blast (dust) pipeline compensator abnormity expansion joint.
Expansion joint is widely used in the cold and hot compensation of pipeline, and the widespread usage expansion joint is a singel-ply bellows at present, form by a plurality of wave bands, if the pipe expansion amount is big, then corresponding just need of bellows wave band increases, the utility model has been done improvement on original singel-ply bellows basis, adopt double-ply bellows for reducing the bellows size, only just can reach the requirement compensation rate with two wave bands.
The utility model is by inner corrugated pipe 1,3, and outward corrugated tube 2,4 is formed, and it is characterized in that: two-layer bellows adopts the argon arc welding assembly welding to connect one in the joint.Hot blast (dust) pipeline compensator abnormity expansion joint can be made into height (diameter) 0.3～7 meter various series specification according to the pipeline construction needs.
The special-shaped expansion joint of this kind passes through the angular deflection of two ends bellows when making compensator work, the steel pipe windup-degree is realized its lateral displacement, when an end interface is traversing in the middle of making, this end internal layer bellows tension, outer pressurized, the outer bellows tension of opposite side, internal layer pressurized, then the two ends bellows produces an angular displacement, the result of two opposite angular displacement synthesis makes two end interfaces realize transversion malposition, with laterally moving of compensation pipeline.Owing to adopted two-layer bellows, the internal layer bellows is recessed to outer bellows, and the connecting tube length in the middle of can making extends greatly, thereby makes its lateral displacement can be very big, to solve the big and contradiction of installing space curtailment of lateral displacement.
This kind compensator structure compactness, the portraitlandscape compensation rate is bigger, is the new equipment of compensator.
Along with the improvement and the requirement increase of design and manufacturing process, though special-shaped expansion joint device is made relatively difficulty, because its advantage can be adopted by people gradually
Claims (2)
1, hot blast (dust) pipeline compensator abnormity expansion joint device is by inner corrugated pipe 1,3, and the special-shaped expansion joint that outward corrugated tube 2,4 constitutes is characterized in that selecting for use two wave band expansion joints to form.
2, according to claim 1 described special-shaped expansion joint device, line pipe 1,3 and outward corrugated tube 2,4 are formed in it is characterized in that, two ends connect the two ends pipeline by board-like and tubular type flange and use.
