Abstract
The utility model relates to a flange and belongs to the technical field of flange equipment design. The flange comprises a first flange plate and a second flange plate. Mounting holes corresponding to the first flange plate and the second flange plate are formed on the first flange plate and the second flange plate, and bolts are tightly screwed with nuts through the mounting holes in the first flange plate and the mounting holes in the second flange plate. The flange is characterized in that a round of raised sealing gaskets is arranged around the mounting holes on two sides of the first flange plate, a round of grooves matching with the raised sealing gaskets is arranged around the mounting hole on one side of the second flange plate contacting with the first flange plate, and a round of raised gaskets is arranged around the mounting hole on the other side. 2-10 mounting holes are formed on the first flange plate and the second flange plate. The flange is reasonable and simple in structure, easy to manufacture, is capable of effectively avoiding water from leaking to the mounting holes in real use, avoiding the bolts from oxidation and rustiness and avoiding the bolts from being unable to be screwed out of the mounting holes.
Description
Technical field
The utility model relates to a kind of flange, belongs to flange equipment design field.
Background technique
Flange is again flange plate or bead, flange be make pipe and pipe and and the interconnective part of valve, be connected in pipe end.The general paired use of flange, a pair of flange, by the mounting hole of mutual correspondence is set, well connects pipeline through mounting hole by links such as bolts.Existing flange mounting hole sealing is poor, and bolt, through mounting hole, in use tends to occur that seepage is in mounting hole, causes bolt oxidation and rusting, even can cause bolt from mounting hole, to take out, and affects pipeline follow-up maintenance.
Model utility content
The purpose of this utility model is in order to address the above problem, provide a kind of simple and reasonable, manufacture easily, flange that mounting hole sealability is high.
The purpose of this utility model is achieved through the following technical solutions: a kind of flange, comprise the first flange plate, the second flange plate, on the first flange plate, the second flange plate, be equipped with the mounting hole of mutual correspondence, bolt is screwed and is connected with nut by the mounting hole on the mounting hole on the first flange plate and the second flange plate, it is characterized in that, on the first described flange plate, the surrounding of both sides mounting hole is equipped with the sealing gasket of a circle projection; The surrounding of the side mounting hole that described the second flange plate contacts with the first flange plate is provided with the circle groove matching with protruding sealing gasket, and the surrounding of opposite side mounting hole is provided with the sealing gasket of a circle projection.
Mounting hole on described the first flange plate, the second flange plate all has 2-10.
The utility model is rational in infrastructure simply, the manufacturing is easy, and by the utility model, on the first flange plate, the surrounding of both sides mounting hole is provided with the sealing gasket of a circle projection; The surrounding of the side mounting hole that the second flange plate contacts with the first flange plate is provided with the circle groove matching with protruding sealing gasket, and the surrounding of opposite side mounting hole is provided with the sealing gasket of a circle projection.In concrete use, when the first flange plate and the second flange plate are used in combination, the sealing gasket of the first flange plate projection inserts on the first flange plate in the circle groove matching with protruding sealing gasket, the opposite side of the first flange and the second flange connecting part is protruding sealing gasket simultaneously, make bolts and nuts tightly on densification packing, in use often effectively avoided occurring that seepage is in mounting hole, prevent from causing bolt oxidation and rusting and even can cause bolt from mounting hole, to take out, facilitated pipeline follow-up maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 first flange plate, 2 second flange plate, 3 mounting holes, 4 sealing gaskets, 5 grooves.
