Abstract
The invention relates to a flange and belongs to the technical field of design of flange equipment. The flange comprises a first flange plate and a second flange plate; both the first flange and the second flange are provided with corresponding mounting holes; and bolts pass through the mounting holes in the first flange plate and the mounting holes in the second flange plate to be screwed down and connected with nuts. The flange is characterized in that the peripheries of the mounting holes at both sides of the first flange plate are provided with convex sealing gaskets; the periphery of each mounting hole at one side of the second flange plate, which is in contact with the first flange plate, is provided with a circle of groove matched with the convex sealing gaskets; the periphery of each mounting hole at the other side of the second flange plate is provided with a circle of convex sealing gasket; and 2 to 10 mounting holes are respectively formed in the first flange plate and the second flange plate. The flange has a reasonable and simple structure and is easy to produce and manufacture; and in the specific using process of the flange, water is often effectively prevented from being leaked into the mounting holes; and the condition that the bolts are oxidized and rusted and even cannot be taken out of the mounting holes is prevented.
Description
Technical field
The present invention relates to a kind of flange, belong to flange device design technical field.
Background technique
Flange is again flange plate or bead, and flange is that pipe and pipe are reached and the interconnective part of valve, is connected in pipe end.The general paired use of flange, a pair of flange passes mounting hole by links such as bolts pipeline is well connected by the mounting hole of mutual correspondence is set.Existing flange mounting hole sealing is poor, and bolt passes mounting hole, in use tends to occur seepage in mounting hole, causes the bolt oxidation and rusting, even can cause bolt to take out from mounting hole, affects the pipeline follow-up maintenance.
Summary of the invention
The objective of the invention is in order to address the above problem, provide a kind of simple and reasonable, manufacture easily, flange that the mounting hole sealability is high.
The objective of the invention is to be achieved through the following technical solutions: a kind of flange, comprise the first flange plate, the second flange plate, be equipped with the mounting hole of mutual correspondence on the first flange plate, the second flange plate, bolt by the mounting hole on the first flange plate be connected mounting hole on the flange plate and screw with nut and be connected, it is characterized in that the sealing gasket that is equipped with a circle projection all around of both sides mounting hole on described the first flange plate; Be provided with the circle groove that the sealing gasket with projection is complementary around the contacted side mounting hole of described the second flange plate and the first flange plate, be provided with the sealing gasket of a circle projection around the opposite side mounting hole.
Mounting hole on described the first flange plate, the second flange plate all has 2-10.
The present invention rational in infrastructure simple, manufacture easily, by the present invention, on the first flange plate the both sides mounting hole around be provided with the sealing gasket of a circle projection; Be provided with the circle groove that the sealing gasket with projection is complementary around the contacted side mounting hole of the second flange plate and the first flange plate, be provided with the sealing gasket of a circle projection around the opposite side mounting hole.In concrete the use, the first flange plate matches with the second flange plate when using, the sealing gasket of projection inserts on the first flange plate in the circle groove that the sealing gasket with projection is complementary on the first flange plate, the opposite side of the first flange and the second flange connecting part is the sealing gasket of projection simultaneously, so that bolts and nuts are tightly on the densification packing, in use often effectively avoided seepage occurring in mounting hole, prevent from causing the bolt oxidation and rusting and even can cause bolt from mounting hole, to take out, made things convenient for the pipeline follow-up maintenance.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure: 1 first flange plate, 2 second flange plate, 3 mounting holes, 4 sealing gaskets, 5 grooves.
Embodiment
The present invention is described further below in conjunction with accompanying drawing and description of drawings thereof.
