Part of the body and the sealing washer, it has last cylinder boss including rectangle flange main part, the last surface machining of rectangle flange main part to go up the flange body, and upward processing has the seal groove on the cylinder boss, and the processing all around of rectangle flange main part has connect the via hole, and the center of rectangle flange main part processes there is the centre bore, and processing has the conical ring on the centre bore, and the conical ring links to each other with the transition of annular cover, and the setting of lower cylinder boss is at the lower surface of rectangle flange main part. This rectangle flange simple structure, it is convenient to make, can be applied to narrow and small installation space, and it is convenient that this flange of while overhauls.
Description
Technical field
The utility model relates to flange disk device field, particularly relates to a kind of rectangular flange.
Background technique
Usually, under the enabled condition of space, it is all that circular flange connects that conventional pipelines connects.In spatial condition not permission situation (as ground proximity metope etc.), pipeline connects for being threaded, but it is not the reliability that is threaded is poor, easy to assemble during maintenance, therefore design a kind of rectangular flange and can to solve in narrow space situation that reliable to connect this rectangular flange maintenance simultaneously convenient.
Model utility content
The purpose of this utility model is to provide a kind of rectangular flange, and this rectangular flange structure is simple, easily manufactured, can be applied to narrow and small installing space, and this flange maintenance is simultaneously convenient.
In order to realize above-mentioned technical characteristics, the purpose of this utility model is achieved in that a kind of rectangular flange, it comprises upper flange body, lower flange body and seal ring, described upper flange body comprises rectangular flange main body, the upper surface of rectangular flange main body is processed with cylinder boss, upper cylinder boss is processed with seal groove, the surrounding of rectangular flange main body is processed with connecting through hole, the center of rectangular flange main body is processed with center hole, center hole is processed with tapered collar, tapered collar is connected with annular sleeve transition, and lower cylinder boss is arranged on the lower surface of rectangular flange main body.
Described seal ring is arranged on the seal groove inside of upper flange body and reaches sealing purpose by coordinating between upper flange body and the upper cylinder boss of lower flange body.
Described seal ring adopts O RunddichtringO, and seal ring adopts nitrile rubber to make.
Described upper flange body and lower flange body all adopt stainless steel material to make.
Described upper flange body and lower flange body all adopt Cr18Ni9Ti stainless steel to make.
By being fixedly connected with through the stay bolt connecting through hole between described upper flange body and lower flange body.
The utility model has following beneficial effect:
When needs are at small space mounting flange, first upper flange body is connected with a pipeline, then lower flange body is connected with another pipeline, the seal groove again seal ring being arranged on upper flange body after being connected is inner, then the upper cylinder boss of upper flange body and lower flange body is matched, pass the through hole of upper flange body and lower flange body by stay bolt after working good thus two flange bodies are fixedly linked.By seal ring, two flange connections are effectively sealed simultaneously.
And rectangular flange structure is simple, easily manufactured, sealing leakage-proof effect is good, and disassembly process is simple, easy to maintenance, can be promoted the use of on a large scale in engineering reality.
