Abstract
The utility model provides an expansion joint of a vacuum pipe, wherein a sleeve is sleeved at the two terminals of the vacuum pipe and a sealing ring is lined between the sleeve and the terminals, characterized in that: a corrugated pipe is sleeved on the periphery of the sleeve and pipes are connected with the two ends of the corrugated pipe and the expansion joint has double-way sealing with good sealing function and the corrugated pipe has protection function on the joint. A leak-free expansion joint is provided for the vacuum pipe communication.
Description
Technical field
The utility model relates to the pipeline of vacuum pipe traffic, specifically a kind of slip joint of vacuum pipe.
Background technique
More and more deficienter current of non-renewable energy resources, which kind of energy consumption is big, and the modern means of communication that expense is high will be low by energy consumption, and fireballing vacuum pipe traffic substitutes.But the seal request of vacuum pipe is very high, and especially the tie point slip joint can be made displacement movement when temperature change, so tie point loses heart easily.
Summary of the invention
In order to overcome the disappointing easily defective of flexible node that vacuum pipe connects, the utility model provides a kind of slip joint of vacuum pipe, and this slip joint can not only accomplish that tie point keeps one's end up, and has higher intensity.
The utility model solves the technical measures that its technical problem takes, connect sleeve pipe on the tie point of vacuum pipe, liner seal ring between the inwall of sleeve pipe and the company of the pipeline outer wall, in the outer ring of sleeve pipe, be inserted in bellows, the two ends of bellows are connected with vacuum pipe respectively, and its contact welds or seals with seal ring.Such slip joint; when temperature change produces displacement; the joint of two pipelines moves in sleeve pipe; stop air leakage by seal ring; bellows has been the second road seal action; and the protection joint is not subjected to the corrosion of extraneous factor, and such slip joint can play a good protection when preventing to lose heart, and prevents the purpose of losing heart thereby reach the vacuum pipe slip joint.
The beneficial effects of the utility model are, do not have the slip joint that loses heart and require for vacuum pipe traffic provides a kind of, and simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the slip joint of vacuum pipe.
Among the figure, 1, pipeline, 2, bellows, 3, sleeve pipe, 4, seal ring, 5, pipeline.
Embodiment
In Fig. 1, the joint of pipeline 1 and pipeline 5 is inserted in the sleeve pipe 3, and lining is gone into seal ring 4 between sleeve pipe and pipe coupling, goes into bellows 2 in the outer race of sleeve pipe 3, and bellows and pipe coupling seal with welding or with seal ring.
Claims (1)
1, the slip joint of vacuum pipe traffic is inserted in sleeve pipe in two joints of vacuum pipe, and lining is gone into seal ring between sleeve pipe and the joint, and it is characterized in that: the outer race at sleeve pipe is gone into bellows, and the two ends of bellows connect the two ends of vacuum pipe.
