Background
In the field construction process, in the connection between the current pipeline, can often appear the connection between the different pipe diameters, then, to these complicated various pipe connections, generally adopt the pipe fitting to connect the shaping, the pipe fitting that needs is of a great variety, and hardly make statistics of the demand of all pipe fittings, consequently, two kinds of even multiple pipe fittings that appear often weld and come up to satisfy the pipeline demand, if in case the problem of rosin joint appears in the welding process, the pipeline is in the use in future, very easy problem appears, give the pipeline problem in the use in future easily, and a plurality of pipe fittings weld to take time, waste energy and waste money, need many times installation and debugging, not only installation effectiveness is not high, and stability in the use is also not good.
Disclosure of Invention
An object of the utility model is to overcome the not enough of prior art existence, and provide a simple structure, installation effectiveness height, the good multi-functional welding pipe fitting of stability.
The utility model aims at accomplishing through following technical scheme, this kind of multi-functional welded pipe fitting includes the body, the body has a plurality of reducing sections through integrative stretch forming, just the reducing section is followed the axial of body is arranged in proper order and is arranged, through changeover portion transition forming between the adjacent reducing section.
Preferably, the variable-diameter sections are arranged in sequence from a small diameter to a large diameter along the axial direction of the pipe body.
Preferably, the variable diameter sections are annular pipes, and the size difference of the inner diameters R between the adjacent variable diameter sections is 5-10 mm.
Preferably, the inner diameter R of the variable diameter section at the head end is 10 to 20mm, and the inner diameter R of the variable diameter section at the tail end is 50 to 100 mm.
Preferably, the transition section is a hollow circular truncated cone-shaped pipeline, one end face of the transition section is combined with the end face of the small-caliber reducer section on one side, and the other end face of the transition section is combined with the end face of the large-caliber reducer section on the other side.
The utility model has the advantages that: by designing the multifunctional welding pipe fitting, all requirements on reducing joints with different calibers in engineering installation can be almost met, the installation cost is saved, and the installation efficiency is improved; different diameter joint to different demands can cut this multi-functional welded pipe fitting through specialized tool and realize the demand of different reducing during the installation, then installs and welds the product of cutting, has just once realized the pipeline installation.
Drawings
Fig. 1 is a schematic view of a main-view cross-sectional structure of the multifunctional welded pipe of the present invention.
The reference numbers in the drawings are respectively: 1. a pipe body; 11. a diameter-changing section; 12. a transition section.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawing 1: the utility model comprises a pipe body 1, wherein the pipe body 1 is made of copper, stainless steel or alloy material; the pipe body 1 is integrally formed with the variable-diameter sections 11 in a stretching mode, and the variable-diameter sections 11 are sequentially arranged along the axial direction of the pipe body 1, so that all requirements of engineering installation on different-diameter joints with different calibers can be almost met, the installation cost is saved, and the installation efficiency is improved; different diameter joint to different demands can cut this multi-functional welded pipe fitting through specialized tool and realize the demand of different reducing during the installation, then installs and welds the product of cutting, has just once realized the pipeline installation. Because of the internal diameter R size between the adjacent reducing section 11 is inconsistent, consequently, through 12 transitional forming of changeover portion between the adjacent reducing section 11, through 12 transitional forming of changeover portion end moreover, not only make the intensity of whole body 1 strengthen, it is also more convenient in the machine-shaping in addition.
Due to the diameter difference between the two pipelines, in order to make the fluid flow smoother and prevent local stress from being generated in the process of connecting the two pipelines through the pipe fittings, the variable-diameter sections 11 are sequentially arranged from a small caliber to a large caliber along the axial direction of the pipe body 1, namely, the variable-diameter sections 11 are distributed in a step shape along the axial direction of the pipe body 1.
In order to adapt the pipe fitting to the two pipelines, the variable-diameter sections 11 are annular pipelines, and the size difference of the inner diameter R between the adjacent variable-diameter sections 11 is 5-10 mm; the inner diameter R of the variable diameter section 11 at the head end is 10 to 20mm, and the inner diameter R of the variable diameter section 11 at the tail end is 50 to 100 mm. For example: the inner diameter of the port of one pipeline is 15mm, the inner diameter of the port of the other pipeline is 60mm, at this time, the inner diameter R of the variable diameter section 11 at the head end is 15mm, the inner diameter R of the variable diameter section 11 at the tail end is 60mm, then the inner diameter R of the variable diameter section 11 at the middle position is 25mm, 35mm, 45mm, 55mm or the variable diameter sections 11 with variable difference values, as long as the size difference of the inner diameter R between the adjacent variable diameter sections 11 is 5-10 mm and the specification caliber meeting the industrial standard, and then the variable diameter section 11 at the middle position has various inner diameters, for example, the inner diameter of the port of one pipeline is 35mm, then the variable diameter sections 11 at the 15mm section and the 25mm section can be cut by special tools, so that one pipe fitting can be applied to the pipelines with various different calibers, in engineering construction, convenience is brought to workers, and the pipeline installation can be realized at one time, the installation cost is saved, the installation efficiency is improved, and the multifunctional installation requirement of the pipe fitting is really met.
The transition section 12 is a hollow circular truncated cone-shaped pipeline, one end face of the transition section 12 is combined with the end face of the small-caliber variable-diameter section 11 on one side, and the other end face of the transition section 12 is combined with the end face of the large-caliber variable-diameter section 11 on the other side; therefore, in the pipe cutting process, as long as the required diameter-changing section 11 with the inner diameter size is reserved, the diameter-changing section 11 with the other size is cut off through the transition section 12, so that the length of the required diameter-changing section 11 with the inner diameter size cannot be shortened, and the welding requirement between the pipe and the pipeline can be met.
The present invention is not limited to the above embodiments, and any change is made on the shape or material composition, and all the structural designs provided by the present invention are all the deformation of the present invention, which should be considered within the protection scope of the present invention.
