Description
Technical field
The utility model relates to mechanical fastener technical field, particularly relates to a kind of novel flange device.
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.
In addition traditional flange plate adopts pad as black box, there is screw when connecting and cross locking and easily cause the rotten tooth of silk mouth locked during use; Heavily tear flange open in overhaul of the equipments or unloading process, gasket seal easily tears, and long-time uses that pad is aging easily causes poorly sealed leaking.
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 novel flange device, comprises pipeline (1), flange plate (2), groove (3), seal ring (4), stiffener (5), stiffening rib (6), screw (7), pin-and-hole (8), locating stud (9); Described flange plate (2) is welded with pipeline (1) by stiffening rib (6); Described stiffening rib (6) is connected to the top margin position of flange plate (2); Described stiffener (5) is used for connecting adjacent stiffening rib (6);
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;
Described first flange plate (2'-) is provided with groove (3), described second flange plate (2'') surface is provided with seal ring (4), described seal ring (4) is stuck in groove (3) towards the side of the first flange plate (2'-) and coordinates with the first flange plate (2'-), and described seal ring (4) is against on the second flange plate (2'') towards the side of the second flange plate (2'').
Further, described stiffening rib (6) adopts the welding manner of fillet joint.
Further, described groove (3) is circular groove, and described seal ring (4), groove (3) and flange plate (2) are located on same medial axis.
Further, described groove (3) cross section is trapezoidal.
The utility model beneficial effect is compared with prior art:
Can bear higher working pressure, 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; The cooperation of groove and seal ring solves the not tight leakiness water problem of conventional planar flange seal.
