Embodiment Construction
[0010] Such as figure 1 As shown, an expansion joint with a position limit includes a left cylinder 1, a right cylinder 6, an inner sleeve 3, and a bellows 5. The inner sleeve 3 is welded in the right cylinder 6, and the left cylinder 1 and the right Bellows 5 are welded between cylinders 6 , and a limit ring 2 is also welded on left cylinder 1 , and there is a distance between limit ring 2 and inner sleeve 3 . Prevent the bellows 5 from being damaged due to excessive thermal expansion and cold contraction. An outer cover tube 4 is also housed outside the bellows 5, and one end of the outer cover tube 4 is welded on the right cylinder 6, and the other end is clearance fit with the left cylinder 1. The bellows 5 is effectively protected.

The invention provides an expansion joint with a limiter. The expansion joint comprises a left barrel, a right barrel, an inner sleeve and a corrugated pipe, wherein the inner sleeve is welded in the right barrel; the corrugated pipe is welded between the left barrel and the right barrel; a limiting ring is also welded on the left barrel; a space is formed between the limiting ring and the inner sleeve; an outer cover barrel is also arranged outside the corrugated pipe; and one end of the outer cover barrel is welded on the right barrel, and the other end of the outer cover barrel is in clearance fit with the left barrel. The expansion joint has the advantages of simple product structure, reliable limiting and long service life, and prevents the corrugated pipe from being damaged.
Description
technical field [0001] The invention relates to a telescopic device, in particular to an expansion joint with a limit. Background technique [0002] The expansion joints currently used in industrial pipelines generally adopt a sleeve-type structure. The bellows are welded between the left cylinder and the right cylinder. Generally, they do not have a limit mechanism. Due to thermal expansion and contraction during use, the bellows may easily In addition, there is no protective device outside the bellows, and the service life is short. Contents of the invention [0003] In order to overcome the problem that the existing expansion joint itself does not have a limit mechanism, the bellows may be easily damaged due to thermal expansion and contraction during use. In addition, there is no protection device outside the bellows and the service life is short. The present invention provides a limiter. bit of expansion joint. [0004] The technical solution adopted by the present ...
