Abstract
The utility model provides an expansion joint with limiting function, which comprises a left barrel, a right barrel, an inner sleeve and a corrugated pipe. The inner sleeve is welded in the right barrel; the corrugated pipe is welded between the left barrel and the right barrel; and a limiting ring spaced with the inner sleeve is welded on the left barrel. An outer covering cylinder is arranged at the outside of the corrugated pipe, one end of the outer covering cylinder is welded on the right barrel body and the other end of the outer covering cylinder is in clearance fit with the left barrel. The expansion joint has the beneficial effects that the expansion joint is simple in structure, reliable in limiting and long in service life, and prevents the damage of the corrugated pipe.
Description
Technical field
The utility model relates to a kind of expansion device, and is 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, the deficiency that working life is short, and it is a kind of with spacing expansion joint that the utility model provides.
The technological scheme that its technical problem that solves the utility model adopts 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 beneficial effects of the utility model are that product structure is simple, and are spacing reliable, prevented the damage of bellows, long service life.
Description of drawings
The utility model is described in further detail 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.
