Abstract
The invention discloses a flange connection structure which comprises flanges and pipelines. The flanges are connected through the pipelines. The flanges are sleeved on the pipelines. A convex stage is arranged at the outer side of each pipeline. A concave stage matched with the convex stage is arranged on an inner ring of each flange. The invention has the advantage that: because the flanges are movable and not fixed, the end faces of the pipelines which are used for connecting the flanges are only butted, then two flanges are rotated to the hole sites and connected by using bolts consistently; the butted flanges are adjusted very conveniently; the movable flanges are located in the axial direction by the convex stages at the outer side of the pipelines, and the concave stages on the inner rings of the flanges are matched with the convex stages at the outer sides of the pipelines, so that the butted flanges are incapable of rotating in circumference; and therefore the connection reliability of the movable flanges and the leakproofness after butting of the movable flanges are guaranteed.
Description
Technical field
The present invention relates to a kind of flanged connecting structure.
Background technique
With the parts that flange connects, flange all is directly to weld together with parts such as pipeline, valves usually, thereby then two flanges is connected parts with the bolt butt joint.These parts generally all are to be in it to fix unmodifiable position originally, or parts often need to keep the consistent relatively of some position when connecting, even weld again and adjust the butt hole position with the flange that these parts weld in advance, but flange butt hole position still can exist deviation to adjust when butt joint connects, cause parts to connect or there are problems such as weld seam imprecision after connecting in the welding part because of bolton, the difficulty of connection and welding requirements are very high.
Summary of the invention
Goal of the invention: at the problems referred to above, the purpose of this invention is to provide a kind of reliably, flanged connecting structure easily, reduce and connect difficulty.
Technological scheme: a kind of flanged connecting structure, comprise that flange, flange connect the pipeline that is depended on, described flange is enclosed within on the described pipeline, and there is boss in the described pipeline outside, and described flange inner ring offers the concave station that is complementary with described boss.
The end face that the described pipeline of position deviation is set of described boss.
Beneficial effect: compared with prior art, advantage of the present invention is that the flange activity is unfixing, only need flange is connected the pipeline end face butt joint of being depended on, then two flanges being turned to the Kong Weiyi bolt of applying connects and to get final product, the abutted flange adjustment is very convenient, and in axially locating, the boss outside the concave station of flange inner ring and the pipeline is to cooperating to the flange of activity for the boss in the pipeline outside, flange after the butt joint circumferentially can't be rotated, thereby guarantee reliability that loose flange connects and the leakproofness after the butt joint.
Description of drawings
Fig. 1 partly cuts open schematic representation for structure of the present invention;
Fig. 2 partly cuts open schematic representation for mated condition of the present invention;
Fig. 3 partly cuts open schematic representation for another mated condition of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiments only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, a kind of flanged connecting structure comprises that flange 1, flange 1 connect the pipeline 2 that is depended on, flange 1 is enclosed within rotatable activity on the described pipeline 2, there is boss 3 in pipeline 2 outsides, and flange 1 inner ring offers the concave station 4 that is complementary with boss 3, the end face that position deviation pipeline 2 is set of boss 3.
Shown in accompanying drawing 2,3, when butt joint connects, it is tight that flange is connected the pipeline end face butt joint of being depended on, then two flanges being turned to the Kong Weiyi bolt of applying connects and to get final product, the boss in the pipeline outside to the flange of activity in axially locating, the boss in the concave station of flange inner ring and the pipeline outside is to cooperating, and the flange after the butt joint circumferentially can't be rotated.
