Abstract
The utility model discloses a combined ring flange, comprising a ring flange face 4 and a butting ring 1, which is characterized in that the ring flange face 4 is a circular part with hole in the middle, bolt perforations 7 are evenly distributed in the circular ring, the diameter of the inner hole is bigger slightly than the outer diameter of the pipe work 8, the edge of the inner hole butting surface is provided with a chamfer 5, another surface of the inner hole is provided with a reinforced projection ring 6, the butting ring 1 is a circular part provided with inner hole 2 in the middle, the thickness of the butting ring corresponds to the thickness of the connection pipe wall,a welding fusion 3 which is butting welded with connection pipe 8 is machined on the butting hole of inner hole 2, the diameter of inner hole 2 is same as the outer diameter of butting pipe, a regular shallow slot is machined on butting surface of butting ring. Ring flange with maximum volume and most material consumption would be manufactured with low cost and high intensity material in the utility model, which can not only ensure intensity of pipe connection but also save material cost, and can save a mount of expensive material.
Description
Technical field
The utility model is a kind of pipe fitting flange connecting dish that is used for.
Technical background
General flange plate is a kind of annulus that is welded as a whole with the mouth of pipe, and the endoporus of annulus inserts the pipe end that will dock.In insertion end weld bond is arranged, annulus is evenly equipped with bolt penetration hole, and a protruding ring is arranged on the endoporus of flange plate interface, and well-regulated groove on the ring is used for folder one deck sealing gasket when butt joint, in case its slip.In order to guarantee pipe fitting join strength and flex resistance, flange plate is general to be adopted and pipeline material identical materials, and the big thickness of its external diameter is also bigger.So flange plate cost of material height.
Summary of the invention
The utility model purpose is to disclose a kind of modular flange dish.
The utility model is made up of flange surface 4 and butt joint ring 1, it is characterized in that: described flange surface 4 is middle ring parts that have endoporus, uniform bolt penetration hole 7 on the annulus, the aperture of endoporus is slightly larger than pipe fitting 8 external diameters, butt joint face at endoporus is processed with chamfering 5 along the place, on the another side of endoporus, have one to strengthen protruding ring 6, described butt joint ring 1 is a middle ring part that has endoporus 2, butt joint ring thickness is equivalent to the connecting tube wall thickness, the butt joint face of endoporus 2 is processed with the bevel for welding 3 with connecting tube 8 butt ends welding usefulness along the place, endoporus 2 diameters are identical with the butt tube external diameter, also process well-regulated shallow trench on the interface of butt joint ring, butt joint ring adopts the material identical materials with pipe, and flange surface 4 adopts the low enough materials of intensity of cost.
The utility model is made volume maximum and the maximum flange surface of consumptive material of lower-cost high-strength material, can guarantee the pipeline join strength, again can the economical with materials cost.For example, for the stainless steel pipeline, flange surface can be with cast steel or cast iron, and cost reduces by 70%, it is done after the preservative treatment suitable working life with stainless steel, can save a large amount of expensive material.
Description of drawings
Fig. 1 is the utility model section of structure;
Fig. 2 is the utility model user mode figure.
Embodiment
As shown in Figure 2, the connecting tube 8 that material is identical is an one with docking boxing earlier.Then flange surface is enclosed within connecting tube 8, slides into the butt joint ring place.Flange surface 4 is that the butt joint face of a middle endoporus is processed with chamfering 5 along the place, is to fit tightly with butt joint ring in order to guarantee, all there is the combinations thereof flange plate that is assembled into the butt end of each pipe.Connect with bolt according to a conventional method and be one, when being used for anticorrosion pipeline, flange surface can be done preservative treatment.
