Description
Technical field
The utility model belongs to mechanical fastener technical field, and in particular to a kind of lengthening elbow.
Background technique
Two pipeline sections of existing elbow are usually short tube, and when use connects supervisor on the end of two short tubes respectively
Road, however in the restricted situation in some fabricating yards, main pipeline can not be connected in the end of short tube, it is therefore desirable to by elbow
One end lengthening processing, to facilitate installation.But the lengthening end of elbow is when by biggish axial stress and radial stress
It can be deformed, reduce the bonding strength and service life of elbow.
Utility model content
The purpose of the utility model is to provide a kind of lengthening elbows, improve bonding strength and the use of the lengthening pipeline section of elbow
Service life.
The utility model provides the following technical solution:
A kind of lengthening elbow, the lengthening elbow include the first pipeline section and the second pipeline section angled therebetween, second pipe
Section is lengthening pipeline section；The root of second pipeline section is equipped with the stiffening plate of arc, and the stiffening plate and second pipeline section are concyclic
The heart, the welding with reinforcement plate is in the top of second pipeline section；It further include upright gusset, the front end and bottom end point of the gusset
It is not welded on the root and the stiffening plate of first pipeline section.
Preferably, the root of second pipeline section is equipped with matched first limiting slot of arc length with the stiffening plate, described
The bottom wall of stiffening plate is embedded and is welded in first limiting slot.
Preferably, the depth of first limiting slot is the 1/10-1/5 of the second pipeline section wall thickness.
Preferably, the top of the stiffening plate is equipped with matched second limiting slot of bottom thickness with the gusset, described
The bottom wall of gusset is embedded and is welded in second limiting slot.
Preferably, the thickness at the top of the gusset is less than the thickness of the gusset bottom.
Preferably, the length of the second limiting slot is greater than the bottom wall length of gusset.
Preferably, the length of the stiffening plate is greater than the length of the gusset.
Preferably, the end of first pipeline section and second pipeline section is respectively equipped with the flange seat protruded outward.
The beneficial effects of the utility model are: reinforcement of the utility model in the root of the second pipeline section of lengthening setting arc
Plate, and stiffening plate is located at the top of the second pipeline section, since stiffening plate has certain thickness and length, to increase second
The radial and axial intensity of pipeline section root avoids the second pipeline section root larger by stress and occurs deforming or be broken；?
Gusset is welded on one pipeline section and stiffening plate, increases the bonding strength of the first pipeline section and the second pipeline section, ensure that the use of elbow
Service life；Since gusset is upright setting, it is easy to be hit and damaged, therefore gusset is welded on stiffening plate, rather than
It is directly welded on the second pipeline section, when gusset is damaged and needs replacing, new muscle can be directly welded on stiffening plate
Plate impacts without the main body tube wall to the second pipeline section, ensure that the service life of elbow.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of the part A-A in Fig. 1.
In the figure, it is marked as 1. first pipeline sections；2. the second pipeline section；21. the first limiting slot；3. stiffening plate；31. the second limit
Slot；4. gusset；5. flange seat.
Specific embodiment
As depicted in figs. 1 and 2, a kind of lengthening elbow lengthens the first pipeline section 1 and second that elbow includes mutual angle in 90 °
Pipeline section 2, the second pipeline section 2 are to lengthen pipeline section；It is the stiffening plate 3 of arc, stiffening plate 3 that the root weld of second pipeline section 2, which has cross section,
With the concyclic heart of the second pipeline section 2, to make stiffening plate 3 be tightly attached to the top of the second pipeline section 2, equivalent to increase the second pipeline section 2
Thickness at portion, and stiffening plate 3 has certain length, improves radial and axial stress resistance energy herein；This elbow
It further include upright gusset 4, the front end and bottom end of gusset 4 are respectively welded on the root and stiffening plate 3 of the first pipeline section 1, gusset 4
It for subtriangular structure, plays a supporting role to the first pipeline section 1 and the second pipeline section 2, enhances the first pipeline section 1 and the second pipeline section
2 bonding strength.
The root of second pipeline section 2 is equipped with matched first limiting slot 21 of arc length with stiffening plate 3, and the bottom wall of stiffening plate 3 is embedding
And if being welded in the first limiting slot 21.First limiting slot 21 makes stiffening plate 3 will not convenient for quickly positioning stiffening plate 3 when welding
It is slided on circular tube wall, improves installation effectiveness and installation accuracy, ensure that the consistency of Product jointing quality.
The depth of first limiting slot 21 is the 1/10-1/5 of 2 wall thickness of the second pipeline section.The depth of the first limiting slot 21 is limited, is dropped
Low intensity effect of first limiting slot 21 to the second pipeline section main body tube wall.
The top of stiffening plate 3 is equipped with matched second limiting slot 31 of bottom thickness with gusset 4, and the bottom wall of gusset 4 is embedded
And it is welded in the second limiting slot 31.Second limiting slot 31 improves installation effectiveness, protects convenient for quickly positioning gusset 4 when welding
The consistency of Product jointing quality is demonstrate,proved.
The thickness at 4 top of gusset is less than the thickness of 4 bottom of gusset, since the second pipeline section 2 is to lengthen pipeline section, gusset 4
It is thicker close to the thickness at the second pipeline section, to increase gusset 4 to the support strength of the second pipeline section 2.
The length of stiffening plate 3 is greater than the length of gusset 4, and stiffening plate is longer, that is, increases stiffening plate to the axis of the second pipeline section 2
To reinforcement ability.The length of second limiting slot 31 is greater than the bottom wall length of gusset 4, so as to according to the use condition of elbow and
Operating condition, selects the gusset of different length specification, and using flexible is good.
The end of first pipeline section 1 and the second pipeline section 2 is respectively equipped with the flange seat 5 protruded outward, convenient for the two of elbow
End is separately connected main pipeline.
The utility model first mills out the first limiting slot 21 in the root of the second pipeline section 2, in stiffening plate 3 when installing production
Surface on mill out the second limiting slot 31, then stiffening plate 3 is welded in the first limiting slot 21, by the bottom insertion of gusset 4 the
In two limiting slots 31, while the root of the first pipeline section 1 is forward resisted, then gusset 4 is welded and fixed.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
