Abstract
The utility model relates to the technical field of the bellow compensator, in particular to a heat resistant and wear resistant type bellow compensator, which comprises a sylphon bellows and a end tube; wherein, the sylphon bellows and the end tube are connected to form an integral structure. The bellow compensator is characterized in that a high-temperature and wear resistant bush is arranged inside the sylphon bellow; a high-temperature resistant and heat insulated material layer is filled and arranged between the sylphon bellow and the bush. The bellow compensator has the advantages of simple, compact and reasonable structure, integral lightness, heat resistance, wear resistance, good compensating effect, difficult leakage of ashes, assurance of not-too-high temperature of the outer surface of the sylphon bellow in the course of use, long service life and enormous saving of the industrial cost, and is especially suitable for being bused on the ash discharge pipes of the large-sized circulating fluidized bed boilers as well as the pipelines which require high-temperature resistance and wear resistance.
Description
[technical field]
The utility model relates to a kind of FlexbleJoint technical field, particularly a kind of heat-resistant, wear-resistant type FlexbleJoint.
[background technique]
In the prior art, be used for the pipeline expansion compensation device of large circulating fluidized bed boiler, be non-metal compensator, it is made of fire brick layer and adiabator layer, is provided with a non-metal expansion joint between the two.Its defective is, whole wall thickness of this compensator and volume are bigger, the device body is heavy, heat-resistant, wear-resistant poor performance, lime-ash are easy to leak, and compensation effect is relatively poor, and working life is shorter, be generally some months, because of blowing out once will directly cause economic loss, so frequent replacing compensator brings serious economic burden to enterprise.
[summary of the invention]
Task of the present utility model provides a kind of rational in infrastructure, heat-resistant, wear-resistant, long service life, the FlexbleJoint that compensation effect is good.
The technical solution of the utility model is as follows: a kind of heat-resistant, wear-resistant type FlexbleJoint, comprise bellows, end pipe, bellows is managed to be connected with end and is formed in integrative-structure, it is characterized in that: in bellows, be provided with floor height temperature anti-wearing liner, fill between bellows and the lining and be provided with the high temperature resistant heat insulation material layer.
Described bellows outer surface is provided with the high temperature resistant heat insulation protection sleeve.
The beneficial effects of the utility model are: simple in structure, compact, reasonable, whole light and handy, heat-resistant, wear-resistant, compensation effect is good, and the difficult leakage of lime-ash, can guarantee during use that the bellows hull-skin temperature can be too not high, its long service life, can save industrial cost greatly, be specially adapted to use on the large circulating fluidized bed boiler scum pipe, be applicable to that also other needs on the high temperature resistant wear-resistant pipeline.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is bellows, and 2 are the end pipe, and 3 is lining, and 4 is protection sleeve.
[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Shown in Figure 1, bellows 1 is connected with end pipe 2 and is formed in integrative-structure, is provided with floor height temperature anti-wearing liner 3 in bellows, and filling is provided with the high temperature resistant heat insulation material layer between bellows and the lining, is provided with high temperature resistant heat insulation protection sleeve 4 at the bellows outer surface.
Claims (2)
1. a heat-resistant, wear-resistant type FlexbleJoint comprises bellows, end pipe, and bellows is managed to be connected with end and is formed in integrative-structure, it is characterized in that: be provided with floor height temperature anti-wearing liner in bellows, fill between bellows and the lining and be provided with the high temperature resistant heat insulation material layer.
