Description
Technical field
The utility model relates to mechanical fastener technical field, particularly relates to a kind of flange apparatus.
Background technique
Flange makes pipe and the mutual flange of pipe be make pipe and the interconnective part of pipe, and in pipeline connection area, flange is played vital position by general use.The kind of flange has a variety of, butt welding welded flange has been widely used in the industry owing to having the advantages such as not yielding, good seal, the pipeline of the pipeline that be applicable to this flange pressure or temperature fluctuate widely or high temperature, high pressure and low temperature, also for carrying the pipeline of expensive, inflammable, explosive medium.In present many chemical pipelines, all there is the operating mode of high pressure, under the impact of strong pressure, the life-span of a lot of flange is all very of short duration, and the infringement of flange directly will have influence on whole work system, in some corrosion-prone operating modes, end face of flange can lose efficacy because of the erosion of corrosion materials.At present, for the research of flange compression resistance, be connected to pipe end meaning power all on the material and preparation process of flange, but ignore structural design to the impact of compression resistance.The design of its structure is on the impact of compression resistance.Therefore, therefore intensity, the compression resistance exigence of flange improve, and develop a kind of pressure-proof flange with anti-high pressure, can prevent the flange of material corrosion from being very important simultaneously.
Simultaneously when flange matches between two, for being all plane-plane contact between two component flanged plates, often there is eyelet deviation, when closing up pairing, often causing bias, sliding phenomenon, increase the difficulty of installing and closing up.
Model utility content
The utility model is exactly the deficiency that will overcome more existing flanges, provides a kind of flange apparatus, and this flange apparatus both can bear higher working pressure, and material also can be prevented the corrosion of flange, has structure simple simultaneously, installs and closes up function easily.
The utility model have employed following technological scheme:
A kind of flange apparatus, comprises pipeline (1), flange plate (2), anticorrosive coat (3), stiffening rib (4), stiffener (5), screw (6), pin-and-hole (7), locating stud (8); Described flange plate (2) is welded with pipeline (1) by stiffening rib (4); Described stiffening rib (4) is connected to the top margin position of flange plate (2); Described stiffener (5) is used for connecting adjacent stiffening rib (4); Described anticorrosive coat (3) is arranged on the end face of flange plate (2);
Described flange plate (2) comprises the first flange plate (2'-) and the second flange plate (2''), described first flange plate is at least provided with a pin-and-hole (7); Described second flange plate (2'') is provided with at least one locating stud (8), and described locating stud (8) and pin-and-hole (7) correspondence are arranged.
Further, described stiffening rib (4) adopts the welding manner of fillet joint.
Further, described anticorrosive coat (3) is polytetrafluoroethylene film layer.
The utility model beneficial effect is compared with prior art:
Higher working pressure can be born; Prevent material to the corrosion of flange; Structure stability is good, and structure is simple, easily manufactured.
By the connection of locating stud and pin-and-hole, can directly be closed up by two components, the phenomenon of slippage without acceptance of persons, decreases and closes up difficulty.

Embodiment
Below in conjunction with drawings and Examples, a kind of flange apparatus is described further.
Shown in composition graphs 1, Fig. 2, Fig. 3, a kind of flange apparatus that the utility model relates to, comprises pipeline 1, flange plate 2, anticorrosive coat 3, stiffening rib 4, stiffener 5, screw 6, pin-and-hole 7, locating stud 8; Described flange plate 2 is welded with pipeline 1 by stiffening rib 4; Described stiffening rib 4 is connected to the top margin position of flange plate 2; Described stiffener 5 is used for connecting adjacent stiffening rib 4; Described anticorrosive coat 3 is arranged on the end face of flange plate 2;
Described flange plate 2 comprises the first flange plate 2'-and the second flange plate 2'', described first flange plate is at least provided with a pin-and-hole 7; Described second flange plate 2'' is provided with at least one locating stud 8, and described locating stud 8 and pin-and-hole 7 correspondence are arranged.
Further, described stiffening rib 4 adopts the welding manner of fillet joint.
Further, described anticorrosive coat 3 is polytetrafluoroethylene film layer.
Description for the understanding of embodiment be only for help understand the utility model, instead of be used for restriction of the present utility model.Those skilled in the art all can utilize thought of the present utility model to carry out some and change and change, as long as its technological means does not depart from thought of the present utility model and main points, still within protection domain of the present utility model.
