Abstract
The utility model discloses a flange structure connected with an electricity transmission pipe tower steel pipe in the field of electricity transmission pipe towers, in particular to a novel hubbed flange with a strain groove.
Description
Technical field
The utility model relates to the flange arrangement technical field that connects electroduct tower steel pipe, is a kind of hubbed flange of Novel belt strain groove specifically.
Background technology
Flange is widely used in the connection of electroduct tower steel tubular structure.The flange connected for electroduct tower steel tubular structure now mostly is the hub W.N flange, what adopt is the pipe flange standard of transporting fluid, be integrated forging and form, have very high strength and stiffness, this fluid line flange can meet the demands to the seal connected and the pressure that bears fluid.But adopt the flange of this fluid line flange standard manufacture to connect be used to the steel tubular structure of transmitting electricity, have following shortcomings:
1. in work progress, when welded steel pipe, under high temperature action, the end face of the flange warpage that easily deforms.
2. in use, under the bending load effect, flange one side is subjected to pulling force, one side is stressed, and because the flange rigidity is excessively strong, strain occurs hardly and distribute unloading stress, stress is concentrated, easily make the weld edge cracking, or make the bending of tensile region bolt or cracking, or make flange screw edge cracking.
3. forging product mass production capabilities deficiency, be difficult to meet the need of market.
4. the uniformity of forging product and reliability are not high, and the production qualification rate is not high.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of hubbed flange with the strain groove.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of hubbed flange of Novel belt strain groove.It is characterized in that, have the strain groove at the flange end face, described strain groove is opened the inboard at screw.
Preferably, the cross section of described strain groove is arc.
Preferably, the cross section of described strain groove is triangle.
Preferably, the cross section of described strain groove is waveform.
Preferably, the cross section of described strain groove is square.
Compared with prior art, the present invention has following advantage:
1. reliability and the safety of product have been improved
Due to the strain groove having been arranged, in work progress, when welded steel pipe, under high temperature action, the end face of the flange warpage that can not deform.
Due to the strain groove having been arranged, under the bending load effect, strain can occur in the strain groove, thereby has unloaded stress, and in use weld edge is not easy to crack, and the tensile region bolt is not flexible, cracking, and flange screw edge is not easy to crack yet.Thereby guaranteed the reliability and security of product.
2. the saving material, reduce costs
The hubbed flange of Novel belt strain groove has reached the optimum organization of structural mechanics and the mechanics of materials, has saved in a large number material, and the structural timber of unit mass can bear larger power transmission.
3. the integrated production technology of precision-investment casting makes the uniformity of product high, and the production qualification rate significantly improves.
4. relatively existing forging product, can produce in batches in a large number, meets the need of market.
The accompanying drawing explanation
Fig. 1 is that a kind of Novel belt cross section is the hubbed flange front view of the strain groove of arc.
Fig. 2 is that a kind of Novel belt cross section is the hubbed flange top view of the strain groove of arc.
Fig. 3 is that a kind of Novel belt cross section is the hubbed flange front view of leg-of-mutton strain groove.
Fig. 4 is that a kind of Novel belt cross section is the hubbed flange top view of leg-of-mutton strain groove.
Fig. 5 is that a kind of Novel belt cross section is the hubbed flange front view of corrugated strain groove.
Fig. 6 is that a kind of Novel belt cross section is the hubbed flange top view of corrugated strain groove.
Fig. 7 is that a kind of Novel belt cross section is the hubbed flange front view of square strain groove.
Fig. 8 is that a kind of Novel belt cross section is the hubbed flange top view of square strain groove.
The specific embodiment
For making technical scheme of the present invention clearer, the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment
A kind of Novel belt cross section is the hubbed flange of the strain groove of arc, and as shown in Figure 1,1 is flange, and 11 are the strain groove, and 12 is neck flange, and 13 is screw, and 14 is weld seam, and 2 is steel pipe, and 3 is bolt nut.
Above the present invention is described in detail, in literary composition, the application specific case is set forth principle of the present invention and embodiment, and the explanation of above embodiment is just be used to helping to understand method of the present invention and core concept thereof.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
