Abstract
The utility model specifically discloses a kind of compound flange apparatus, comprises pipeline, flange plate, groove, seal ring, screw, pin-and-hole, locating stud; The end face of the flange plate near pipeline is equiped with boss; Described flange plate comprises the first flange plate and the second flange plate, described first flange plate is at least provided with a pin-and-hole; Described second flange plate is provided with at least one locating stud, and described locating stud and pin-and-hole correspondence are arranged; Described first flange plate is provided with groove, and described second flange plate surface is provided with seal ring, and described seal ring is stuck in groove towards the side of the first flange plate and coordinates with the first flange plate, and described seal ring is against on the second flange plate towards the side of the second flange plate.The utility model is by the connection of locating stud and pin-and-hole, and can directly be closed up by two components, the phenomenon of slippage without acceptance of persons, decreases and close up difficulty; The distortion that welding produces can be resisted simultaneously, save following process, reduce manpower, save cost, and then reduce cost of production.
Description
Technical field
The utility model relates to mechanical fastener technical field, particularly relates to a kind of compound 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.
But, main Placement between the existing each assembly of automobile exhaust system is that plane face flange connects, for ensureing the planarity requirements≤0.5mm of its junction surface of sealing, and flange is all welded on outlet pipe, yielding because welding, can not meet the demands, often need following process or school type to solve problem.
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 it is simple that this flange apparatus has structure simultaneously, installs and closes up function easily.
The utility model have employed following technological scheme:
A kind of compound flange apparatus, comprises pipeline (1), flange plate (2), groove (3), seal ring (4), screw (7), pin-and-hole (8), locating stud (9); The end face of the flange plate (2) near pipeline (1) is equiped with boss (5);
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 pipeline (1) and boss (5) welding.
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; The distortion that welding produces can be resisted simultaneously, save following process, reduce manpower, save cost, and then reduce cost of production.
