Abstract
The utility model discloses a kind of boiler final reheater outlet transition pipe, and this transition conduit comprises body, is provided with the pipeline of this body through in body; Body comprises along its pipeline axial and connects successively and the Part I be interconnected, transition portion and Part II; The internal diameter of Part I is greater than the internal diameter of Part II; Transition portion is equal with the internal diameter of Part I with one end internal diameter that Part I connects, the internal diameter of transition portion is reduced to the one end connecting Part II gradually by the one end connecting Part I, and transition portion is equal with the internal diameter of Part II with one end internal diameter that Part II connects.The utility model lengthens the length of transition conduit transition portion, reduce the excessive angle of transition portion, improve cutter groove, wedge angle, round-corner transition radius, increase the fineness of transition conduit inwall simultaneously, thus the boiler leakage blowing out accident avoided transition conduit that fracture occurs and cause, ensure the normal work of boiler.
Description
Technical field
The utility model relates to a kind of boiler pipe part, is specifically related to a kind of boiler final reheater outlet transition pipe.
Background technology
At present, the situations such as the final reheater outlet transition pipe of apparatus of thermo-electric power boiler exists cutter groove, wedge angle, round-corner transition radius is inadequate, fineness inadequate, wall unevenness.Cause stove final reheater outlet transition short tube easily to rupture, cause boiler leakage blowing out accident.
Utility model content
The utility model provides a kind of boiler final reheater outlet transition pipe, improves transition portion length, reduces excessive angle, avoid transition conduit to rupture.
For achieving the above object, the utility model provides a kind of boiler final reheater outlet transition pipe, and this transition conduit comprises body, is provided with the pipeline of this body through in body; Be characterized in,
Above-mentioned tubular body comprises along its pipeline axial and connects successively and the Part I be interconnected, transition portion and Part II;
The internal diameter of above-mentioned Part I is greater than the internal diameter of Part II;
Above-mentioned transition portion is equal with the internal diameter of Part I with one end internal diameter that Part I connects, the internal diameter of transition portion is reduced to the one end connecting Part II gradually by the one end connecting Part I, and transition portion is equal with the internal diameter of Part II with one end internal diameter that Part II connects.
The internal diameter of above-mentioned transition portion is reduced with linear relationship to the one end connecting Part II by the one end connecting Part I.
Corner dimension between the madial wall of above-mentioned transition portion and the madial wall of Part I is 166 degree.
Above-mentioned transition portion is set to 820 millimeters along the length of its axis.
The external diameter size of the Part I of above-mentioned tubular body, transition portion and Part II is constant along pipeline axial.
The outer end of above-mentioned Part II and the junction of Part II lateral wall are provided with inclined-plane.
Above-mentioned Part II length is vertically greater than Part I length vertically.
The utility model boiler final reheater outlet transition pipe is compared with the transition conduit of prior art, its advantage is, the utility model lengthens the length of transition conduit transition portion, reduce the excessive angle of transition portion, improve cutter groove, wedge angle, round-corner transition radius, increase the fineness of transition conduit inwall simultaneously, thus the boiler leakage blowing out accident avoided transition conduit that fracture occurs and cause, ensure the normal work of boiler.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model boiler final reheater outlet transition pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, further illustrate specific embodiment of the utility model.
As shown in Figure 1, disclose a kind of embodiment of boiler final reheater outlet transition pipe, this transition conduit includes the columniform body that external diameter is 60 millimeters, the pipeline of this body through is provided with in body, inner-walls of duct fineness can be arranged by technological requirement, in routine use, inner-walls of duct fineness can the technological ability of prior art be set to the highest.
Body comprises along its pipeline axial and connects successively and the Part I 1 be interconnected, transition portion 3 and Part II 2.
The external diameter size of the Part I of body, transition portion and Part II is constant along pipeline axial.
Part II length is vertically greater than Part I and transition portion length vertically.Wherein transition portion is set to 820 millimeters along the length of its axis.
Wherein, the internal diameter of Part I 1 is greater than the internal diameter of Part II 2, and wherein the internal diameter of Part II 2 is evenly set to 31 millimeters, and the internal diameter of Part I 1 is evenly set to 52.2 millimeters.One end that transition portion 3 is connected with Part I 1, its internal diameter is equal with the internal diameter of Part I 1.And one end that transition portion 3 is connected with Part II 2, its internal diameter is equal with the internal diameter of Part II 2.The internal diameter of this transition portion 3 is reduced to the one end connecting Part II 2 gradually by the one end connecting Part I 1, the changeover portion that before forming Part I 1 and Part II 2, internal diameter changes.
Preferably, the internal diameter of transition portion 3 is reduced with linear relationship, to ensure transition portion 3 inwall fineness to the one end connecting Part II 2 by the one end connecting Part I 1.
Further, the madial wall of transition portion 3 and the madial wall of Part I towards Part II 2 extended line between angle be 14 degree, the corner dimension namely between the madial wall of transition portion 3 and the madial wall of Part I 1 is 166 degree.
As shown in Figure 1, along the outer end of Part II and the junction of Part II lateral wall, be also provided with the inclined-plane around Part II end edge, this inclined-plane is used for groove during transition conduit welding.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
