Embodiment
Referring to figs. 1 through Fig. 4, a kind of steel oil pipe edge-breaking flange, but the pipeline that is applicable to enlarging connects, it comprises that two of being fixed on the attachment face lean on attachment face to the flange plate 1 of dress and bottom and are provided with the meson 2 of pod apertures 7, two flange plate 1 of the present utility model all adopt the A3 steel, meson 2 adopts No. 45 steel, and these two kinds of steel are used more extensive, and have certain plasticity and toughness, mechanical strength is big, cutting ability is good and have good comprehensive mechanical properties.Described two flange plate 1 are provided with fixed hole, and described two flange plate 1 are provided with a tapered indentations 5, and pipeline 8 external diameters that tapered indentations 5 can connect as required rationally are provided with, and latter two tapered indentations 5 of 1 pair of dress of described two flange plate forms a cone shape hole; The outer surface of described meson 2 is arranged to the conical surface that adapts with cone shape hole, after described meson 2 is flush-mounted in described cone shape hole, the surface of cone shape hole and meson 2 conical surfaces form the clamp port of clamping pipeline 8 horn mouth tube walls, the width of this clamp port can design according to the thickness of tube wall, promptly realizes by the size that changes meson 2 conical surfaces.
During use at first the tapering according to meson and tapered indentations pipeline opening to be connected is carried out enlarging, make the mouth of pipe be horn-like, and on attachment face corresponding to the punching tapping of the mounting point of flange plate fixed hole.The generally suitable horn mouth of drawing together into 37 degree of enlarging in this step, so the gradient of cone shape hole is 37 degree in the utility model, correspondingly the gradient of conical surface also is 37 degree.Place meson in the horn mouth then and be aligned to connection mouth, again two flange plate are fixed on the attachment face by bolt 3, compress the horn mouth of pipeline, the horn mouth of the conical surface that forms by tapered indentations and the conical surface clamping pipe of meson, finish the connection of pipeline, the liquid in the pipeline is from pod apertures 7 circulations of meson 2.
This shows and do not need welding in the whole erection process, install simple, be convenient to dismounting, it is low to be compared to FERRULETYPE steel pipe joint screw-down torque, and can prevent stubborn, assemble up also attractive in appearance, be easy to produce and processing, and because meson, steel pipe closely is connected mutually with flange plate, has good comprehensive mechanical properties, can bear higher working pressure, vibrationproof is arranged, advantage such as cracky not, improve connection stability and reliability, be applicable to injection machine, boats and ships, engineering machinery, mining machineries etc. are hydraulic parts such as steel pipe mechanically, aluminum pipe, but the connection that lining is moulded enlarging pipelines such as metal tube brings many facilities for the connection work of pipeline.
As further improvement of the utility model, described two flange plate 1 to dress all extend to both sides along the axle center of tapered indentations 5 makes tapered indentations 5 formation step-like, and correspondingly cone shape hole formation two ends are that cylinder, centre are step-like for round platform; It is that cylinder, centre are step-like for round platform that described meson 2 extends to form two ends along its axle center to both sides, described clamp port is formed by the round table surface of cone shape hole and the round table surface and the path cylndrical surface of path cylndrical surface and meson 2, and the path cylndrical surface of the path cylndrical surface of meson 2 and cone shape hole leaned the inside and outside tube wall at the clamping pipeline respectively after pipeline was held; The cylndrical surface, big footpath of described cone shape hole cylndrical surface, big footpath and meson 2 is tangent, rear stub 1 is installed closely cooperates with meson 2.These structures have further strengthened the reliability that pipeline connects.
Further improve as of the present utility model, in order to strengthen sealing effect, described meson of the present utility model 2 bottoms and conical surface are provided with annular recess 6, in the described annular recess 6 seal ring 4 is installed all, has prevented the conical surface of meson 2 bottoms and attachment face, meson 2 and the leakage of oil problem between the pipeline effectively.
Because its external diameter of pipeline and the pipe thickness of different model are standardized on the market, flange of the present utility model designs according to GB/T3639-2000 and German DIN2391-1994 seamless steel pipe and wall thickness, flange size then adopts the design of SAE dimensional standard, can produce the edge-breaking flange that is applicable to the different model pipeline in batches, also can be at concrete pipeline specific design.
