Abstract
The utility model discloses a split type flange which is expected to be universal. The split type flange comprises more than two flange blocks identical in structure, the flange blocks spliced into an annular structure. The end portion of one flange block adjacent to another flange block is provided with an adjacent surface, and a connecting lug is arranged on the external side of the adjacent surface of each flange block and extends outwardly along the diameter direction of the flange body. The connecting lugs are provided with connecting through holes, and bolts for connecting adjacent flange blocks are inserted in the connecting through holes. The flange body can be installed in a pipe fitting matching with the internal diameter of the flange body, as shown in figure 2, or installed in a pipe fitting greater than the internal diameter of the flange body, as shown in figure 3, or installed in a pipe fitting smaller than the internal diameter of the flange body, as shown in figure 4. The split type flange is highly universal, and is especially suitable for construction projects requiring temporarily constructing pipe fittings. The distribution and management of the flange blocks are much easier.
Description
Technical field
The utility model relates to a kind of flange, and more particularly, it relates to a kind of Split flange.
Background technique
In pipeline is installed, conventionally utilize bolt, by flange, two segment pipes or pipe fitting product are connected, at present general adpting flange mainly with fixed be main, fixed flange is generally shaped by cast inblock, also has to adopt to be welded and fixed.Yet for flat mouth class fitting structure, be not suitable for adopting fixed flange to connect, although also there is at present the Split flange of use to connect, can meet the installation needs of part flat mouth class fitting structure, but its form structure is global design, for different pipe fittings, do not adopt personalized designs, in actual production and using, lack versatility, particularly to those, need to build the engineering of pipe fitting temporarily, the construction work mobility that cause is built is temporarily higher, after using a period of time, just need to remove to shift again to build, therefore easily there is the difficulty in allocation manager in the flange of different size.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of Split flange of highly versatile.
For achieving the above object, the utility model provides following technological scheme: a kind of Split flange, comprise flange body, by two, the above and identical flange piece of structure splices structure ringwise to described flange body, described flange piece is provided with adjacent surface near the end of adjacent flanges piece, described flange piece all convexes with connection lug near the outside of adjacent surface, described connection lug stretches out along flange body diametric(al), this connection lug is provided with connecting through hole, is equipped with for connecting the bolt of adjacent flanges piece in described connecting through hole.
On described flange piece, be equipped with the axis flange connecting hole parallel with flange body axis.
Described flange connecting hole is the setting of kidney-shaped structure.
Described flange body inner side is along the circumferential direction provided with frictional groove.
A kind of Split flange, comprise flange body, by two, the above and identical flange piece of structure splices structure ringwise to described flange body, described flange piece is provided with adjacent surface near the end of adjacent flanges piece, described flange piece all convexes with connection lug near the outside of adjacent surface, described connection lug stretches out along flange body diametric(al), and this connection lug is provided with connecting through hole, is equipped with for connecting the bolt of adjacent flanges piece in described connecting through hole.By adopting technique scheme, the flange piece that the complete flange body of script is designed to a plurality of splicings is bolted, and flange body can be arranged on the pipe fitting suitable with flange body internal diameter, as shown in Figure 2; Also can be arranged on the pipe fitting that is greater than flange body internal diameter, as shown in Figure 3; Can also be arranged on the pipe fitting that is less than flange body internal diameter, as shown in Figure 4, so flange body highly versatile of this structure, on pipe fitting applicable to all kinds of diameters, so be specially adapted to the construction work that those need to build pipe fitting temporarily, and also easily a lot of to the allocation manager of flange piece.

Embodiment
Referring to figs. 1 through Fig. 4, the utility model Split flange embodiment is described further.
A kind of Split flange, comprise flange body 1, by two, the above and identical flange piece 11 of structure splices structure ringwise to described flange body 1, described flange piece 11 is provided with adjacent surface 111 near the end of adjacent flanges piece 11, described flange piece 11 all convexes with connection lug 112 near the outside of adjacent surface 111, described connection lug 112 stretches out along flange body 1 diametric(al), this connection lug 112 is provided with connecting through hole 113, is equipped with for connecting the bolt 2 of adjacent flanges piece 11 in described connecting through hole 113.The flange piece 11 that the complete flange body 1 of script is designed to a plurality of splicings is fixing by bolt 2, and flange body 1 can be arranged on the pipe fitting 3 suitable with flange body 1 internal diameter, as shown in Figure 2; Also can be arranged on the pipe fitting 3 that is greater than flange body 1 internal diameter, as shown in Figure 3; Can also be arranged on the pipe fitting 3 that is less than flange body 1 internal diameter, as shown in Figure 4, so flange body 1 highly versatile of this structure, on pipe fitting 3 applicable to all kinds of diameters, so be specially adapted to the construction work that those need to build pipe fitting 3 temporarily, and also easily a lot of to the allocation manager of flange piece 11.Flange body 1 can be comprised of the even more flange pieces 11 of three, four or five, as best preferred version of the present utility model, flange body 1 is spliced by four identical flange pieces 11 of structure, because the more manufacturing costs of flange piece 11 quantity are just higher, therefore by experiment in conjunction with actual conditions, after the test through a large amount of and actual data analysis, draw, four flange pieces 11 are the quantity of tool cost performance, both effective production control manufacture cost guarantees the stable connection of the flange body 1 that forms and pipe fitting 3 simultaneously.
On described flange piece 11, be equipped with the axis flange connecting hole 114 parallel with flange body 1 axis.On each flange piece 11, be equipped with flange connecting hole 114, all energy is stressed when two flange body 1 axially connect to make each flange piece 11, is conducive to improve steadiness when two flange body 1 are axial to be connected.
Described flange connecting hole 114 is the setting of kidney-shaped structure.Be convenient to the installation location of bolt 2, conveniently make bolt 2 pass when two flange body 1 axially connect, be conducive to improve efficiency of assembling when two flange body 1 are axial to be connected.
Described flange body 1 inner side is along the circumferential direction provided with frictional groove 115.Frictional groove 115 can increase the frictional force of flange body 1 and pipe fitting 3, is conducive to improve flange body 1 and is arranged on the firm degree on pipe fitting 3.
