Description
Technical field
The utility model is related to Industrial Boiler Technology field, a kind of especially a kind of smoke pipe of boiler, and in particular to band
There is the boiler smoke pipe of female.
Background technology
Existing gas fired-boiler is generally three return structures of Horizontal chamber, three return smokes length of tube therein with respect to longest,
Two return smoke pipe is relatively short, because need to consider that the flue gas resistance of boiler is unlikely excessively high, thirdly smoke pipe is generally light used in backhaul
Pipe, but the heat exchange efficiency of light pipe and some deficiencies, there is also similar problems for two return smoke pipe, are facing class in the prior art
During like problem, designer often adjusts the length of each smoke pipe, and then design each cigarette using the method for change boiler size
The exchange capability of heat and length dimension and flue gas resistance of pipe, this method need to do larger change to existing equipment, lead to cost
Over-burden.
For these reasons, the present inventor furthers investigate existing boiler with smoke pipe, to it is to be designed go out one kind
The boiler smoke pipe with female that can be solved the above problems.
Utility model content
In order to overcome the above problem, present inventor has performed sharp studies, design a kind of boiler with female
With smoke pipe, which includes cylindrical smoke pipe ontology, and the female of external compression formation is provided on smoke pipe ontology；
The length value for being provided with the female region is less than the length value of the smoke pipe ontology, the i.e. subregion on the smoke pipe
Female is provided with, heat exchange efficiency can be improved, and can not excessively increase flue gas resistance, it is new so as to complete this practicality
Type.
Specifically, the purpose of this utility model is to provide with a kind of boiler smoke pipe with female,
The smoke pipe includes smoke pipe ontology 1, and the smoke pipe ontology 1 is cylindrical,
The female 2 of external compression formation is provided on the smoke pipe ontology 1；
The length value for being provided with 2 region of female is less than the length value of the smoke pipe ontology 1.
Wherein, the female 2 is arranged on smoke pipe close to end；
The end refers to the region that the flue gas entered in the smoke pipe finally flows through.
Wherein, the smoke pipe is arranged between the flue in boiler and smoke box or is arranged between smoke box and smoke box.
Wherein, the screw pitch of the female 2 gradually changes.
Wherein, along flow of flue gas direction, end is moved closer to, the screw pitch of the female 2 is to taper into.
Wherein, the cup depth of the female 2 gradually changes.
Wherein, along flow of flue gas direction, end is moved closer to, the cup depth of the female 2 gradually increases
Advantageous effect includes possessed by the utility model：
(1) flue gas resistance can not excessively improved according to the boiler smoke pipe provided by the utility model with female
Heat exchange efficiency is improved in the case of power so that integral device manufacturing process is simple, can reduce steel consumption, additionally it is possible to further
Improve boiler efficiency；
(2) it is gradual change with the screw pitch of female on smoke pipe according to the boiler provided by the utility model with female
, so that close to the flow velocity higher of smoke outlet, exchange capability of heat is stronger.

22- females
Specific embodiment
The utility model is further described below by drawings and examples.By these explanations, this practicality is new
The characteristics of type and advantage will become more apparent from clearly.
Dedicated word " exemplary " means " being used as example, embodiment or illustrative " herein.Here as " exemplary "
Illustrated any embodiment should not necessarily be construed as preferred or advantageous over other embodiments.Although each of embodiment is shown in the drawings
In terms of kind, but unless otherwise indicated, it is not necessary to attached drawing drawn to scale.
According to the boiler smoke pipe provided by the utility model with female, as shown in fig. 1, which includes cigarette
Tube body 1, the smoke pipe ontology 1 is cylindrical,
Internal and external threads 2 are provided on the smoke pipe ontology 1；Wherein, outer convex thread 21 is set in smoke pipe inner body wall,
With being provided with female 22 at outer 21 corresponding position of convex thread on the smoke pipe body outer wall 1；
The female 22 on outer convex thread 21 and outer wall on the inner wall is formed via external compression；
The length for being provided with the 2 smoke pipe pipeline section of internal and external threads is less than the total length of the smoke pipe ontology 1.The outside is squeezed
Swaging into female refer on the basis of light pipe, inwardly squeezed in the outside of light pipe so that light pipe deform indent, in
Recess portion is advanced along light pipe with helical wire form, and then forms external screw thread, the height value of China and foreign countries' convex thread 21 of the present invention and interior
The depth value of recessed screw thread 22 is all in the range of 2~5mm；
Be provided with 2 region of internal and external threads length value be generally the smoke pipe ontology 1 length value 1/3~1/2.
Preferably, the internal and external threads 2 are arranged on smoke pipe close to end；
The end refers to the pipeline section that the flue gas entered in the smoke pipe finally flows through.
The smoke pipe is arranged between the flue in boiler and smoke box or is arranged between smoke box and smoke box.When described
When smoke pipe is arranged between the flue in boiler and smoke box, which is commonly referred to as two return smoke pipe, which is generally referred to as
For front smoke box, the end of the two return smoke pipe is close to front smoke box；When the smoke pipe is arranged between smoke box and smoke box, the smoke pipe
Commonly referred to as three backhaul smoke pipes, two smoke boxes are respectively front smoke box and rear smoke box, and the end of the three backhauls smoke pipe is after
Smoke box.
In one preferred embodiment, the screw pitch of the internal and external threads 2 gradually changes.
Specifically, along flow of flue gas direction, the screw pitch of the internal and external threads 2 tapers into.
In one preferred embodiment, the evagination height of the outer convex thread 21 gradually changes, correspondingly, institute
The cup depth for stating female 22 gradually changes.
Specifically, along flow of flue gas direction, the evagination height of the outer convex thread 21 gradually increases；
Along flow of flue gas direction, the cup depth of the female 22 gradually increases, by setting above-mentioned gradual change
Helicitic texture further improves flow velocity of the flue gas in smoke pipe end, improves its exchange capability of heat.
The fingers such as " on ", " under ", " interior ", " outer " " preceding " " rear " it should be noted that term in the description of the present invention,
The orientation or position relationship shown is based on the orientation or position relationship under utility model works state, is for only for ease of description
