Abstract
The utility model relates to an expansion joint which comprises an expansion joint body, a connecting flange which is connected with two ends of the expansion joint body. The expansion joint body is a split type sleeve assembly structure which comprises an outer sleeve and an inner sleeve. One end of inner sleeve is connected with the inside outer sleeve. A lining is arranged in the inner sleeve. The lining is made of high temperature resisted aggregating sealing asbestos. The expansion joint uses the split type sleeve assembly structure. The expansion joint is simple in structure, easy to manufacture and easy to install. The high temperature resisted aggregating sealing asbestos lining is arranged in the inner sleeve so that the high temperature resisting function is improved and the axial extending is guaranteed under high temperature. The expansion joint is good in sealing effects and long in service life.
Description
Technical field
The utility model relates to the device of extraction duct rated displacement, is specifically related to a kind of expansion joint.
Background technique
The additional stress that expansion joint causes because of temperature difference and mechanical vibration for compensation, and be arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can free-extension, the advantages such as reliable operation, functional, compact structure have been widely used in the departments such as chemical industry, metallurgy, nuclear energy.Now widely used expansion joint comprises expansion joint body and the flange that is welded on two ends, wherein expansion joint is integral structure component, complex structure, and two end flange need Site Welding, processing, installation difficulty is large, in two end flange and miscellaneous equipment bolt rigid joint, after the high-temperature heating, axial expansion is restricted, radial deformation is strengthened, cause inner coming off high temperature resistant gathering materials, cause the expansion joint scaling loss, so working life is short.
The model utility content
The utility model purpose is to provide a kind of simple in structure in order to overcome the deficiencies in the prior art, easily the expansion joint of processing and long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of expansion joint, comprise the expansion joint body, and be connected to the adpting flange at expanding body two ends, described expansion joint body is split type sleeve package assembly, comprises urceolus, inner core; Described inner core one end is connected in the urceolus; Be provided with lining in the described inner core; Described lining adopts the high temperature resistant sealing asbestos that gather materials to make.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of expansion joint of the utility model scheme adopts split type sleeve package assembly, and is simple in structure, easily processing and easily installation; In inner core, be provided with the high temperature resistant sealing asbestos lining that gathers materials, both improved resistant to elevated temperatures function, guaranteed again extending axially under the high temperature, good sealing effect, long service life.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is of the present utility model a kind of;
Wherein: 1, adpting flange; 2, urceolus; 3, inner core; 4, lining.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 is a kind of expansion joint described in the utility model, comprises the expansion joint body, is connected to the adpting flange 1 at expanding body two ends, and described expansion joint body is split type sleeve package assembly, comprises urceolus 2, inner core 3; Described inner core 3 one ends are connected in the urceolus 2; Be provided with lining 4 in the described inner core 3; Described lining 4 adopts the high temperature resistant sealing asbestos that gather materials to make.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
