Abstract
The utility model relates to a split flange coupling structure, which comprises two semicircular split monolithic flanges in the same structure; a half attachment bolt hole (1) extends toward the other semicircle at the diameter of each semicircular split monolithic flange; the upper end of the attachment bolt hole (1) at the diameter of the semicircle is provided with a flange through hole (2); and a cambered segment extends from the other end; the extended part is provided with a threaded screw hole (3); the split flange coupling structure is formed in the way that the flange through hole (2) of the semicircular split monolithic flange is jointed with the screw hole (3) of the other semicircular split monolithic flange through thread. The attachment bolt hole (1) is distributed on the split flange coupling structure. Different positions of the split flanges are designed to be thick to different extent; in this way, the split flanges are jointed conveniently, and the flanges are connected with straight butt end pipes conveniently, thus saving the material and the manufacturing cost. Both ends of the split monolithic flanges are designed to be cambered; the thickness is reduced in the axial direction. Accordingly, the split flange coupling structure is beautiful in appearance and the raw materials are saved.
Description
Technical field
The utility model relates to a kind of split type flange connecting structure.
Background technique
In piping erection, utilize bolt usually, by flange two segment pipes or pipe fitting product are linked, at present general connecting flange is many based on fixed, fixed flange, general cast inblock is shaped, and also has the welding adopted fixing; For flat mouthful of class fitting structure, be not suitable for using fastening flange to connect.The split type monolithic flange of a small amount of use connecting structure is at present also arranged, though can satisfy the installation needs of flat mouthful of class fitting structure, but appearance structure is global design, do not adopt personalized designs at different pipe fittings, in actual production and using, increased cost of material, be unfavorable for installing and using quickly and easily.
The model utility content
Problem to be solved in the utility model provides a kind of split type flange connecting structure, and the employed split type monolithic flange appearance structure of this structure is simple, has reduced cost of material and also can install and use quickly and easily.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of split type flange connecting structure is provided, comprise the split type monolithic flange of the identical semicircle shape of two chip architectures, the split type monolithic flange of semicircle shape extends coupling bolt hole at its diameter place half to other semicircle, upper end at the coupling bolt hole at semicircle diameter place is provided with the flange through hole, the other end continues to extend one section radian, the screw hole of rib-loop in prolongation is provided with a band, connecting structure are connected with screw with the screw hole of the split type monolithic flange of another semicircle shape by the flange through hole of the split type monolithic flange of a semicircle shape and form.
Split type monolithic flange is evenly distributed with several coupling bolt holes, and its thickness of distribution coupling bolt hole place reduces and forms a groove; Its two ends are designed to circular-arc, and the thickness at two ends is half of the own thickness of split type monolithic flange; The coupling bolt hole of split type monolithic flange is used for by screw rod, and for ease of installing and locating, bolt hole is designed to the trough type hole; Flange one end is designed to sunk-in through-opening, and the other end is the metric system screw hole, is convenient to the mutual clamping of two split type monolithic flanges.
For ease of being connected of split type monolithic flange and flat mouthful of pipe fitting, according to flat mouthful of pipe fitting outside dimension requirement, in flange and flat mouthful of pipe fitting contacting point, adopt optimal design, its Thickness Design is 3/5 of a flange general thickness at split type monolithic flange middle part distribution coupling bolt hole place; Is 4/5 of flange general thickness at the coupling bolt hole of split type monolithic flange to its Thickness Design of interior ring edge of flange; Split type monolithic flange two ends are designed for arc, and axially reduce thickness, and it is convenient to connect, appearance looks elegant.
A kind of split type flange connecting structure of the utility model, adopt technique scheme, compared with prior art, owing to adopted the connecting mode of the mutual clamping of split type monolithic flange, and split type monolithic flange has been carried out the optimal design of different-thickness, according to flat mouthful of pipe fitting outside dimension requirement, with a flat mouthful of pipe fitting contacting point, different thickness has been designed at the different position of split type monolithic flange, both made things convenient for the connection of split type monolithic flange, make things convenient for flange again and put down being connected of mouthful pipe fitting, saved material simultaneously, saved manufacture cost; The two ends of split type monolithic flange are designed for circular arc, and axially reduce thickness, have reached purpose aesthetic in appearance and that save material.
