Abstract
The utility model provides a concentric reducing pipe which has good applicability and leakproofness and is convenient to use. The concentric reducing pipe is characterized by being a cylindrical hollow pipe body and comprising an inlet pipe and an outlet pipe which are both cylindrical as well as a connecting pipe which is arranged between the inlet pipe and the outlet pipe, wherein the diameters of the inlet pipe and the outlet pipe are different, the circle centers of the inlet pipe and the outlet pipe are on the same straight line, the connecting pipe is conical, one end of the connecting pipe is fixedly connected with one opening of the inlet pipe, and the other end of the connecting pipe is fixedly connected with one opening of the outlet pipe. The concentric reducing pipe is specially suitable for the inlet pipe and the outlet pipe which have different diameters; and axes of the two pipes needed to be connected are arranged on the same straight line, the diameters of the inlet pipe and the outlet pipe can be preset into a plurality of combinations according to the diameter specification of a corresponding standard part, if two pipes with different diameters are needed to be connected, a concentric reducing pipe which accords with the needed specification can be fetched as required, and then welding is realized through opening-to-opening butt joint.
Description
Technical field
The utility model relates to a kind of tubing, especially a kind of Concentric Reducers.
Background technique
Tubing has obtained general use in modern society, is particularly using extremely extensively aspect the draining water conservancy diversion especially, and in the time will connecting the tubing of different bores, just need use the link of tubing.If two pipe diameters that will connect are inequality, then can't realize two tubing being connected to one rightly, and realize interface welded seal effectively by the mode of welding.If must realize the connection of two tubing, then need to twine on the opening end outer wall of the less tubing of diameter therein sealing strip etc. and have flexible Sealing, opening end with the big tubing of diameter is sheathed on the opening end that is wound with Sealing then, thereby being connected and fixed of the tubing that the realization diameter is different, but so then waste time and energy, and sealability is also bad.
Summary of the invention
In order to overcome the deficiencies in the prior art, a kind of a kind of applicability and good airproof performance of providing, Concentric Reducers easy to use are provided the utility model.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Concentric Reducers, it is characterized in that: this Concentric Reducers is the cylindrical hollow body, include and be columnar inlet tube and outer pipe and the connecting tube between inlet tube and outer pipe, different and the center of circle of the diameter of inlet tube and outer pipe is on same straight line, connecting tube is conical, one end of connecting tube is fixedlyed connected with inlet tube one opening, and the other end is fixedlyed connected with outer pipe one opening.
Of the present utility modelly further be set to: axially all being located along the same line of described inlet tube, outer pipe and connecting tube, the inlet tube diameter is greater than the outer pipe diameter, and the inlet tube diameter is not more than the twice of outer pipe diameter.
Of the present utility modelly further be set to: the other end opening of the end that is connected with connecting tube on the described inlet tube is provided with and gets around a mouthful annular slope that is provided with again, the other end opening of end of being connected with connecting tube on the outer pipe is provided with and gets around a mouthful annular slope that is provided with, and described annular slope and connecting tube axis angulation are 30-37.5 °.
The beneficial effects of the utility model are: the utility model is applicable to that specially the diameter of inlet tube and outer pipe is different, and the axis of these two required connection tubing is located along the same line, the diameter of inlet tube and outer pipe can preestablish multiple combination according to the diameter specifications of respective standard part, if the tubing of two different-diameters need connect, just can fetch the Concentric Reducers that meets required specification as required, through port and mouth realizes welding to fetching then.Wherein, the setting of annular slope not only improves the degree of finish of the utility model opening end, makes things convenient for the utility model upper open end to cooperate with the opening end butt joint of required welding tubing, improves the firm degree and the sealability of welding; Also play simultaneously the effect of transition welding part, improved the compressive strength that connects the end on the utility model.Annular slope is 37.5 ° with connecting tube optimal angle that axis becomes.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's a schematic representation.
Fig. 2 is the utility model embodiment's a sectional view.
Embodiment
As shown in Figure 1, 2, present embodiment Concentric Reducers 1 includes and is columnar inlet tube 11 and outer pipe 12 and the connecting tube 13 between inlet tube 11 and outer pipe 12, different and the center of circle of the diameter of inlet tube 11 and outer pipe 12 is on same straight line, connecting tube 13 is conical, one end of connecting tube 13 is fixedlyed connected with inlet tube 11 1 openings, and the other end is fixedlyed connected with outer pipe 12 1 openings.Wherein, axially all being located along the same line of inlet tube 11, outer pipe 12 and connecting tube 13, inlet tube 11 diameters are greater than outer pipe 12 diameters, and the inlet tube Helicopter-11 directly is not more than the twice of outer pipe 12 diameters.The other end opening of end of being connected with connecting tube 13 on the inlet tube 11 is provided with and gets around a mouthful annular slope 14 that is provided with, the other end opening of end of being connected with connecting tube 13 on the outer pipe 12 is provided with and gets around a mouthful annular slope 14 that is provided with, and described annular slope 14 is located at respectively on the interior outer side wall of Concentric Reducers 1 opening end.
In the utility model, this Concentric Reducers 1 is applicable to that specially inlet tube 11 is different with the diameter of outer pipe 12, and the axis of these two required connection tubing is located along the same line, the diameter of inlet tube 11 and outer pipe 12 can preestablish multiple combination according to the diameter specifications of respective standard part, if the tubing of two different-diameters need connect, just can fetch the Concentric Reducers 1 that meets required specification as required, through port and mouth realizes welding to fetching then.Wherein, the twice that inlet tube 11 diameters are not more than outer pipe 12 diameters mainly is in order to improve the hardness requirement of this Concentric Reducers 1, it is not enough to avoid hardness occurring because the diameter gap is too big, and perhaps transition distance is oversize and cause the increase of Concentric Reducers 1 cost of production.In addition, the setting of annular slope 14 not only improves the degree of finish of the utility model opening end, makes things convenient for the utility model upper open end to cooperate with the opening end butt joint of required welding tubing, improves the firm degree and the sealability of welding; Also play simultaneously the effect of transition welding part, improved the compressive strength that connects the end on the utility model.Annular slope 14 is 37.5 ° with connecting tube 13 optimal angle that axis becomes.The utility model can also have other mode of executions, and the technological scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
