Abstract
The utility model provides an eccentric reducing pipe with good application and use convenience. The utility model is characterized in that the eccentric reducing pipe is a cylindrical hollow pipe and comprises a cylindrical inlet pipe, a cylindrical outlet pipe and a connecting pipe between the outlet pipe and the inlet pipe. The diameters of the inlet pipe and the outlet pipe are different, and the centers of the inlet pipe and the outlet pipe are not 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 the one opening of the outlet pipe. The utility model is specially suitable for the occasion that the inlet pipe and the outlet pipe have different diameters, and the axial lines of the two required connecting pipes are not on the same straight line. The diameters of the inlet pipe and the outlet pipe can be preset to be various combinations according to the diameter specifications of the corresponding standard parts. If two pipes with different diameters need to be connected, the eccentric reducing pipe meeting the required specifications can be chosen according to requirement, 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 eccentric reducer.
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, and when causing on the no longer same straight line in the two tubing centers of circle owing to the installation reason, 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, at first need to make the axle center of two pipe fittings to be located along the same line, and then weld by Concentric Reducers fixing, but so then waste time and energy, a lot of to the corresponding raising of engine request.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of applicability good, easy to use eccentric reducer.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of eccentric reducer, it is characterized in that: this eccentric reducer 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 not on same straight line, connecting tube is taper, 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: the axis of described inlet tube, outer pipe and connecting tube is parallel mutually, and is inscribed within on the same point mutually along the circle that radial cross section projection is separately constituted.
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 not 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 eccentric reducer 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 of connecting tube.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 eccentric reducer 1 includes inlet tube 11 and outer pipe 12 and the connecting tube 13 between inlet tube 11 and outer pipe 12 that is circular open, different and the center of circle of the diameter of inlet tube 11 and outer pipe 12 is not on same straight line, connecting tube 13 is taper, 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, the axis of inlet tube 11, outer pipe 12 and connecting tube 13 is parallel mutually, and is inscribed within on the same point mutually along the circle that radial cross section projection is separately constituted.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, and annular slope 14 is 37.5 ° with connecting tube 13 optimal angle that axis becomes.
This inlet tube 11 is different with the diameter of outer pipe 12 in the utility model, and 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 eccentric reducer 1 that meets required specification as required, through port and mouth realizes welding to fetching then.Wherein, 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.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.
