Abstract
The utility model discloses a dual variable diameter three way pipe connector, which comprises a connector body. The connector body comprises two axial openings and a radial opening, wherein, the inner diameter of one axial opening is gradually reduced, and a taper structure is formed, thereby the inner diameter of the two axial openings are not identical. The dual variable diameter three way pipe connector can directly accomplish the switch between the large pipe and the small pipe during the laying of fire pipelines, and other switch parts are not required to be added, thereby a large quantity of installation processes are saved, and the installation speed is effectively increased.
Description
Technical field
The utility model relates to a kind of pipe connecting part, relates in particular to a kind of double diameter-changeable tee pipe fitting joint.
Background technique
The three-way pipeline joint plays an important role in pipe laying, especially in fire protection pipeline is laid, the existing three-way pipeline joint shaft that is used for fire protection pipeline to two openings be identical, in installing and using, can cause by other pipe fitting installation procedure complicated, because existing fire protection pipeline generally is the structure that pipeline successively decreases step by step: come out from total pipeline, what connect successively is 50mm bore pipeline, tee union, 50mm bore short tube, big tubule crossover sub, 40mm bore pipeline, tee union, 40mm bore short tube, big tubule crossover sub, 32mm bore pipeline, tee union, the 32mm pipeline, big tubule crossover sub, the 25mm pipeline.It is big or small and decide that above-mentioned tee union and big tubule crossover sub all comply with the mouth of pipe that it is connected previously, but axial two opening diameters of tee union are identical, when that is to say that working as large diameter pipeline is decremented to small-bore pipe, one section of the bigbore short tube of two kinds of pipeline intermediate demands adjunction, also need big tubule crossover sub, this shows that this structure has not only been wasted material, more wasted the manpower and materials in the installation process.
Summary of the invention
The utility model provides a kind of and can use manpower and material resources sparingly in a large number in installation process, and processes simple double diameter-changeable tee pipe fitting joint.
A kind of double diameter-changeable tee pipe fitting joint comprises joint body, and joint body comprises axial two openings and an opening radially, and the internal diameter at one of them axially open place dwindles gradually and forms the taper structure, makes two axial opening internal diameter differences.
Loss of pressure head when the taper structure helps to reduce internal diameter varies makes the interior flow of fluid of pipeline more unimpeded.
The bore of opening radially can be identical with one of axial two openings, also can be all inequality according to the bore of pipeline needs and axial two openings, like this in three openings on double diameter-changeable tee pipe fitting joint, two kinds even three kinds of bores can be arranged, satisfied the demand of different exterior line bores to greatest extent.
Described axial two openings and opening radially are provided with internal thread or outside thread, can be according to the need of institute's adapter road difference.
Also can be connected with other pipelines by flange as required with axial two openings and opening welded flange radially.
The angle of the axis A of the inwall of described taper structure division and double diameter-changeable tee pipe fitting joint is the 30-60 degree.
The utility model reducing tee joint can directly be finished the transfer process of big tubule, and the centre no longer needs adjunction short tube and big tubule crossover sub, has not only saved material, and has improved installation rate greatly, can save a large amount of manpower and materials.
Description of drawings
Fig. 1 is the structural representation of the utility model double diameter-changeable tee pipe fitting joint.
Embodiment
As shown in Figure 1, the utility model double diameter-changeable tee pipe fitting joint comprises joint body 1, on the axis A direction of joint body 1 two openings is arranged, and vertical axis A radially is provided with an opening.
The opening end internal diameter on right side dwindles gradually and forms taper structure 2 on the A direction of figure medial axis, and the opening internal diameter of this end is less than the internal diameter of axially going up the opposite side opening.
The angle α of the axis A of the inwall of taper structure 2 parts and double diameter-changeable tee pipe fitting joint is 30 degree.
The bore of opening radially is identical with the bore of the axially open of axially going up taper structure 2 one ends, all less than the bore of axis A direction upper left side opening.
According to the bore of the exterior line that is connected with axial last two openings, and taper structure 2 parts length requirement in the axial direction, the angle α of the axis A of the inwall of taper structure 2 parts and double diameter-changeable tee pipe fitting joint can be 40,45,50 or 60 degree.
If angle α crosses the rapid rising that conference causes the pipeline internal drag, angle α is too small, the DeGrain of reducing.
Axial two openings and opening radially are provided with internal thread among the figure, are convenient to connect with exterior line.
