Abstract
The utility model discloses a pipe expansion joint for conveying high-temperature coal ash. The pipe expansion joint comprises an inner sleeve, a first outer sleeve, a second outer sleeve and an expansion corrugated pipe, wherein the inner sleeve is mounted vertically; the upper end of the expansion corrugated pipe is connected with the first outer sleeve; the lower end of the expansion corrugated pipe is connected with the second outer sleeve; and the first outer sleeve is welded on the upper end of the inner sleeve. In comparison with the prior art, the pipe expansion joint provided by the utility model is suitable for high-temperature coal ash conveying, and can endure 900 DEG C high temperature, prolong the service life of pipes, and lower the maintenance rate.
Description
Technical field
The utility model relates to high temperature delivery pipe field, exactly refers to a kind of expansion joint for pipeline that the high temperature coal ash is carried that is applicable to.
Background technique
The expansion joint for pipeline that the coal ash of prior art is carried, be only applicable to the occasion of the highest 400 ℃ of left and right, but temperature is up to 900 ℃ during the discharge of the ashes of boiler, and the swell increment of pipeline under this high temperature is large, there is no again applicable expansion joint, and pipeline life is short.
The model utility content
For above-mentioned defect, the technical problem that the utility model solves is to provide a kind of expansion joint for pipeline that the high temperature coal ash is carried that is applicable to, and can tolerate 900 ℃ of high temperature, has extended the working life of pipeline, has reduced maintenance rate.
In order to solve above technical problem, the expansion joint for pipeline that is applicable to the conveying of high temperature coal ash that the utility model provides, comprise inner sleeve, the first outer sleeve, the second outer sleeve and expansion bellows, described inner sleeve at right angle setting, the upper end of described expansion bellows is connected with described the first outer sleeve, the lower end of described expansion bellows is connected with described the second outer sleeve, and described the first outer sleeve is welded on the upper end of described inner sleeve.
Preferably, the upper end of described expansion bellows and described the first outer sleeve are welded to connect, and the lower end of described expansion bellows and described the second outer sleeve are welded to connect.
Preferably, described expansion bellows is the high temperature resistant stainless steel pipe.
Preferably, the length of described expansion bellows is 300-400mm.
Preferably, the thickness of pipe wall 5-8mm of described inner sleeve.
Preferably, the thickness of pipe wall 1.5-3mm of described the first outer sleeve and the second outer sleeve.
The expansion joint for pipeline that is applicable to the conveying of high temperature coal ash that the utility model provides, comprise inner sleeve, the first outer sleeve, the second outer sleeve and expansion bellows, described inner sleeve at right angle setting, the upper end of described expansion bellows is connected with described the first outer sleeve, the lower end of described expansion bellows is connected with described the second outer sleeve, and described the first outer sleeve is welded on the upper end of described inner sleeve.Make the expansion bellows with exotic material, inner sleeve is resisted the friction of high-temperature material in pipeline, and inner sleeve is not connected with the expansion bellows, and expansive force acts on resistant to elevated temperatures expansion bellows fully, but expansion bellows washing away of managed interior material not.Compared with prior art, the expansion joint for pipeline that is applicable to the conveying of high temperature coal ash that the utility model provides, can tolerate 900 ℃ of high temperature, extended the working life of pipeline, reduced maintenance rate.
The accompanying drawing explanation
Fig. 1 is the structural representation that is applicable to the expansion joint for pipeline of high temperature coal ash conveying in the utility model embodiment, and in figure, the direction of arrow is the mass transport direction.
Embodiment
For those skilled in the art can understand technological scheme provided by the utility model better, below in conjunction with specific embodiment, set forth.
Refer to Fig. 1, this figure is the structural representation that is applicable to the expansion joint for pipeline of high temperature coal ash conveying in the utility model embodiment, and in figure, the direction of arrow is the mass transport direction.
The expansion joint for pipeline that is applicable to the conveying of high temperature coal ash that the utility model embodiment provides, comprise inner sleeve 1, the first outer sleeve 3, the second outer sleeve 4 and expansion bellows 2, inner sleeve 1 at right angle setting, the upper end of expansion bellows 2 and the first outer sleeve 3 are welded to connect, the lower end of expansion bellows 2 and the second outer sleeve 4 are welded to connect, the first outer sleeve 3 is welded on the upper end of inner sleeve 1, and the second outer sleeve 4 does not weld with inner sleeve 1.
Make expansion bellows 2 with exotic material, the inner sleeve 1 of thickening is resisted the friction of high-temperature material in pipeline, inner sleeve 1 is not connected with expansion bellows 2, and expansive force acts on resistant to elevated temperatures expansion bellows 2 fully, but expansion bellows 2 washing away of managed interior material not.
Compared with prior art, the expansion joint for pipeline that is applicable to the conveying of high temperature coal ash that the utility model provides, can tolerate 900 ℃ of high temperature, extended the working life of pipeline, reduced maintenance rate.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.Multiple modification to these embodiments will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
