Description
Technical field
This utility model is related between a kind of different size pipe fitting be connected device, can be used for boiler desuperheater and with its phase
The connection of the sparge pipe afterbody connecting, provides a kind of method of attachment that can play fixation, belongs to boiler tubing technical field.
Background technology
For boiler tubing, there is the pre-buried of the adnexa of various ways specification, such as its stress or guide effect thereon
Plate, or the pipe joint of its measuring point effect, these adnexaes are all connected to a fixed with pipeline by welding manner, but to can not be straight
For connecing the adnexa pipe of welding, alternate manner is needed to reach the purpose being connected and fixed on pipeline.
As shown in figure 1, being the apparatus structure schematic diagram that is connected between a kind of traditional boiler different size pipe fitting, attemperator
When the afterbody of (pipeline) 1 and the pipeline 2 through its inner chamber is connected to a fixed, because the functional requirement of pipeline 2 is it is impossible to directly by two
Individual pipe fitting is welded, thus using the boss 3 being connected with pipeline 2 and support bar 5 compound mode, pipeline 2 is fixed on pipeline 1
On.In detail, as boss 3 one end is connected with pipeline 2, and the fit depressions of other end and support bar 5 one end, thus reach
Arrive the purpose of occlusion, support bar 5 is welded on pipeline 1.In view of the flow area of attemperator (pipeline), the size meeting of pipeline 2
Have certain limitations, the size of connected boss 3 also can it is thus determined that, so boss radius can not possibly be very big, bear Jie
The boss crossing minor radius during the vibration force of shearing force that matter is washed away and sparge pipe will rupture, therefore, this traditional pipe fitting
Between the apparatus structure that is connected have its certain limitation.
Content of the invention
The purpose of this utility model is to provide the structure that is connected between a kind of wider pipe fitting of scope of application, simplifies between pipe fitting
Be connected mode, and the Assimilation and conductivity of power is equally accomplished to simplify.
In order to realize object above, the technical solution of the utility model is to connect between the different size pipe fitting providing a kind of simplification
Connect fixing device, as shown in Figure 2.Perforate on attemperator (pipeline) 1, enables pipeline 2 to pass through, and end is still used in the end of pipeline 2
Lid 6 carries out butt welding sealing, and then passes through pipe joint 7 and right with it for the fixing hole opened on attemperator (pipeline) 1 body
Connect the end cap 8 of weldering to carry out reinforcement and sealing.For this structure, if necessary to consider the requirements such as follow-up maintenance, can fit
Perforate in amplification attemperator (pipeline) 1, and supplement this portion gap using the steel plate 9 being welded on pipeline 2, thus reaching
Purpose to fixed -piping 2.
The device that is connected between the pipe fitting that this utility model provides is being sheared or only need to considered pipeline 2 itself during vibration force
Specification, simplify the Assimilation and conductivity of power, the structure of end cap 6 is also identical with common end cap, need not abnormity improve, simpler can
Lean on.The encapsulating method that this device comprises has two kinds, respectively butt welding and the welding of base full penetration weld, and all encapsulating methods are equal
For the welding manner of maturation process, the problems such as leakage will not be produced.This structure allows excursion larger, is suitable for pipeline 2
Specification limit larger, disclosure satisfy that maintenance etc. require, simple to operate during maintenance.
The invention has the advantage that
1st, apparatus structure is simple, easy processing；
2nd, device assembling mode is ripe, easily reaches prescription；
3rd, device is adaptable, and range is wide.

Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description, but the present invention is not limited to
Below example.
Embodiment 1
As shown in Fig. 2 being the apparatus structure schematic diagram that is connected between a kind of novel pipe fitting, for pipeline 1(such as desuperheat
Device) with smaller conduit 2(such as sparge pipe) be connected.Pipeline 2 passes through the perforate on pipeline 1, and afterbody passes through end cap 6 envelope
Stifled, the perforate on pipeline 1 is sealed and reinforcement by pipe joint 7 and end cap 8.If it is considered that subsequent maintenance need to increase perforate,
Then the gap between pipeline 2 and pipe joint 7 can support filling by steel plate 9.In this structure, end cap 6 structurally variable turns to as figure
Shown in 3, can voluntarily select as needed when specifically used.
Embodiment 2
As shown in figure 4, being the apparatus structure schematic diagram that is connected between a kind of novel pipe fitting, pipeline 2 is provided entirely in pipeline 1
Interior, welded stub connection 7 in the perforate on pipeline 1, the place being different from example 1 is end cap for sealing pipeline 2 and pipe joint 7
For integral type, that is, end cap 10 is the end cap containing (or two) boss, specifically, if this device is not required to consider building site
Remove refitting, then boss outside in pipeline 1 for the end cap 10 as shown can remove, if it is considered that maintenance etc., then end cap 10 is as schemed
Show and coordinate steel plate 9 to reach the purpose of fixed -piping 2 again.
Below only have expressed embodiments of the present invention, its description is more concrete and detailed, but can not therefore understand
It is the restriction to patent of invention scope.It should be pointed out that for the person of ordinary skill of the art, without departing from this
On the premise of bright design, some deformation can also be made and improve, these broadly fall into protection scope of the present invention.
