Abstract
The utility model relates to a desulfurization pottery pipe fitting, including the desulfurization pottery pipe fitting body and with desulfurization pottery pipe fitting welding ring flange together, the terminal surface boss outside welding of ring flange has the turn -ups circle, the turn -ups circle include with ring flange looks welded annular connecting portion and outside end with the anchor ring portion that the annular connecting portion are connected, the internal diameter of anchor ring portion is less than the internal diameter of desulfurization pottery pipe fitting body, anchor ring portion with parallel and the distance of terminal surface boss of ring flange the terminal surface boss predetermined distance of ring flange, thereby the terminal surface boss of ring flange with be formed with between the anchor ring portion be used for filling ceramic protective material with the corresponding side of desulfurization pottery pipe fitting body forms terminal surface ceramic protective layer's region. The utility model discloses can form the layer of ceramic material who forms the protection to the terminal surface of pipe fitting to the terminal surface that prevents the pipe fitting in the use is impaired because of wearing and tearing or corruption because of the unprotect.
Description
Technical field
The utility model belongs to ceramic pipe fitting technical field, and in particular to a kind of desulfurization ceramics pipe fitting.
Background technology
Desulfurization system for thermal power plant has the characteristics that：It is big with corrosivity, abrasion.In desulfurization system for thermal power plant
Used in common steel tube will be damaged using one month, therefore be developed special desulfurization earthenware duct for firepower send out
Power plant desulphurization system.
Current desulfurization earthenware duct is formed using pipe lining ceramic material, and ceramic material is by alundum (Al2O3), carbonization
Silicon, resin composition.Above material is applied to steel pipe inner wall after mixing using specific purpose tool, is through the solidification of 3-4 hours
Can normally use.
In use, it has been found that existing desulfurization earthenware duct be easy in use due to abrasion, corrosion and
Cause to damage, be particularly highly susceptible to attrition and attack at desulfurization earthenware duct flange port, so as to reduce desulfurization ceramics
The service life of pipeline, accordingly, it would be desirable to be improved, to overcome the defect.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem and provide a kind of use for effectively improving pipeline
The desulfurization ceramics pipe fitting in life-span.
For achieving the above object, the utility model is adopted the following technical scheme that：
A kind of desulfurization ceramics pipe fitting, including desulfurization ceramics pipe fitting body and weld together with desulfurization ceramics pipe fitting
Ring flange, the end face outside the boss of the ring flange is welded with flange circle, and the flange circle includes mutually being welded with the ring flange
The anchor ring portion that the annular connecting portion and outboard end for connecing is connected with the annular connecting portion, the internal diameter in the anchor ring portion is less than described
The internal diameter of desulfurization ceramics pipe fitting body；The anchor ring portion is parallel with the end face boss of the ring flange and away from the end of the ring flange
Face boss preset distance, so as to be formed between the end face boss of the ring flange and the anchor ring portion for filling ceramic guarantor
Protective material forms the region of end face ceramic protective layer with the corresponding side in desulfurization ceramics pipe fitting body.
The preset distance is 8-10mm.
The internal diameter in anchor ring portion 3-4mm less than the internal diameter of desulfurization ceramics pipe fitting body.
The utility model is welded with flange circle by the end face outside the boss in the ring flange, so as in the ring flange
End face boss and the anchor ring portion between be formed with for filling ceramic protective material with desulfurization ceramics pipe fitting body
Corresponding side formed end face ceramic protective layer region, so install pipe fitting part when, can by the flange circle pipe
The end face outside filling ceramic material of part, forms the ceramic material layer that the end face to pipe fitting forms protection, so as to use process
In prevent the end face of pipe fitting to be damaged because wearing and tearing or corroding because of unprotect, so as to extend the service life of pipe fitting.
Description of the drawings
The structural representation of the desulfurization ceramics pipe fitting that Fig. 1 the utility model embodiment is provided.
Specific embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
It is shown in Figure 1, a kind of desulfurization ceramics pipe fitting, including desulfurization ceramics pipe fitting body 10 and with desulfurization ceramics
The pipe fitting welding disk of flange 11 together, the ring flange is provided with the Stud connection hole 12 that multiple edges are circular layout, the method
The end face outside the boss of blue disk is welded with the flange circle 13 that section is L shape, and the flange circle includes mutually being welded with the ring flange
The anchor ring portion that the annular connecting portion and outboard end for connecing is connected with the annular connecting portion, the internal diameter in the anchor ring portion is less than described
The internal diameter of desulfurization ceramics pipe fitting body；The anchor ring portion is parallel with the end face boss of the ring flange and away from the end of the ring flange
Face boss preset distance, so as to be formed between the end face boss of the ring flange and the anchor ring portion for filling ceramic guarantor
Protective material forms the region 14 of end face ceramic protective layer with the corresponding side in desulfurization ceramics pipe fitting body.
The structure of flange circle is provided with by more than, a ceramics can be formed on the unshielded face of the outboard end of pipe fitting and is protected
Sheath, and the ceramic material of filling can be made to enrich compression, make ceramic protective layer smooth and solid, and convenient operation, in filling
Finish and after hardening, the flange circle can be destroyed, thus can directly carry out pipe fitting and be connected by ring flange.
Implement, the preset distance is 8-10mm.
Implement, the internal diameter 3-4mm less than the internal diameter of desulfurization ceramics pipe fitting body in the anchor ring portion.
Above analysis is as can be seen that the utility model is welded with flange by the end face outside the boss in the ring flange
Circle, so as to be formed between the end face boss of the ring flange and the anchor ring portion for filling ceramic protective material with institute
The corresponding side for stating desulfurization ceramics pipe fitting body forms the region of end face ceramic protective layer, so in installation pipe fitting part, can be with
By the way that ceramic material is filled on the outside of the end face of pipe fitting in the flange circle, the ceramic material that the end face to pipe fitting forms protection is formed
Layer, so as to the end face for preventing pipe fitting in use is damaged because of unprotect because wearing and tearing or corroding, so as to extend pipe fitting
Service life.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from the utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
