Abstract
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
The present invention relates to a kind of expansion device, especially a kind of with spacing expansion joint.
Background technique
Use the expansion joint at industrial pipeline at present, generally adopt telescoping structure, bellows is welded between left-hand cylinder body and the right cylindrical shell; generally self be not with position-limit mechanism, owing to expand with heat and contract with cold, it is bad to cause bellows to draw easily during use; in addition, the bellows outside does not have protective gear, and working life is short.
Summary of the invention
Be not with position-limit mechanism in order to overcome existing expansion joint self, owing to expand with heat and contract with cold, it is bad to cause bellows to draw easily during use, and in addition, the bellows outside does not have protective gear, and the deficiency that working life is short the invention provides a kind of with spacing expansion joint.
The technical solution adopted for the present invention to solve the technical problems is a kind of with spacing expansion joint, comprise left-hand cylinder body, right cylindrical shell, inner sleeve, bellows, inner sleeve is welded in the right cylindrical shell, be welded with bellows between left-hand cylinder body and the right cylindrical shell, on the left-hand cylinder body, also be welded with a limited ring, a spacing is arranged between limited ring and the inner sleeve.
An exterior cover pipeline also is equipped with in the bellows outside, and an end of exterior cover pipeline is welded in right cylindrical shell, and the other end and left-hand cylinder body are Spielpassung.
The invention has the beneficial effects as follows that product structure is simple, spacing reliable, prevented the damage of bellows, long service life.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is embodiment's a tectonic maps;
Among the figure: 1. left-hand cylinder body; 2. limited ring; 3. inner sleeve; 4. exterior cover pipeline; 5. bellows; 6. right cylindrical shell.
Embodiment
As shown in Figure 1, a kind of with spacing expansion joint, comprise left-hand cylinder body 1, right cylindrical shell 6, inner sleeve 3, bellows 5, inner sleeve 3 is welded in the right cylindrical shell 6, be welded with bellows 5 between left-hand cylinder body 1 and the right cylindrical shell 6, on left-hand cylinder body 1, also be welded with a limited ring 2, between limited ring 2 and the inner sleeve 3 spacing arranged.Prevent that bellows 5 from causing drawing bad hidden danger owing to the amount of expanding with heat and contract with cold is excessive.An exterior cover pipeline 4 also is equipped with in bellows 5 outsides, and an end of exterior cover pipeline 4 is welded in right cylindrical shell 6, and the other end and left-hand cylinder body 1 are Spielpassung.Protected bellows 5 effectively.
Claims (2)
1. one kind with spacing expansion joint, comprise left-hand cylinder body, right cylindrical shell, inner sleeve, bellows, inner sleeve is welded in the right cylindrical shell, is welded with bellows between left-hand cylinder body and the right cylindrical shell, it is characterized in that: also be welded with a limited ring on the described left-hand cylinder body, a spacing is arranged between limited ring and the inner sleeve.
