Abstract
The invention discloses a sleeve joint flange plate component which comprises an inner flange plate and is characterized by further comprising an outer flange plate and a sealing gasket located between the inner flange plate and the outer flange plate, wherein a raised edge is formed on the periphery of the outer flange plate; the outer diameter of the outer flange plate is larger than the diameter of the inner flange plate; the inner diameter of the outer flange plate is equal to the diameter of the inner flange plate; the inner flange plate is located inside the edge of the outer flange plate; a plurality of first screw holes are formed in the side surface of the inner flange plate; and second screw holes corresponding to the first screw holes are formed in the edge of the outer flange plate. The sleeve joint flange plate component has the benefits as follows: a bolt fixing position is changed, so that a bolt can be prevented from penetrating through the sealing gasket to affect the sealing performance of the sealing gasket; and the outer flange plate surrounds the sealing gasket and the inner flange plate, and the raised edge also serves as an outer layer sealing element.
Description
Technical field
The present invention relates to a kind of mechanical fastener, be specifically related to a kind of socket flange component.
Background technique
Flange plate is to make pipe and the interconnective part of pipe, is connected in pipe end, and the sealing that therefore connects is the important parameter characteristic of check flange plate quality, and poor sealing is prone to the phenomenons such as infiltration gas leakage.And up and down two the flange plate circumferential size on the existing flange plate equate to only have one deck pad, in case seepage will appear in the pad wearing and tearing, sealing effect is poor.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of flange component of good seal performance.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of socket flange component comprises inner flange, it is characterized in that, also comprises: outward flange dish, gasket seal between above-mentioned inner flange and outward flange dish; Be formed with the edge of projection on the circumference of above-mentioned outward flange dish, the external diameter of above-mentioned outward flange dish is greater than the diameter of above-mentioned inner flange, and the internal diameter of above-mentioned outward flange dish equals the diameter of above-mentioned inner flange, and above-mentioned inner flange is positioned at the edge of above-mentioned outward flange dish; The side of above-mentioned inner flange is provided with a plurality of the first screws, and the edge of above-mentioned outward flange dish is provided with second screw corresponding with above-mentioned the first screw.
Further, the height of above-mentioned edge protuberance is the summation of the thickness of above-mentioned gasket seal and inner flange.
Further, above-mentioned gasket seal is spiral wound gasket.
Further, also comprise the bolt that passes successively above-mentioned the second screw and the first screw.Above-mentioned bolt is hexagon head bolt, and bolt head has cross recess.
Further, the number of above-mentioned the first screw is 4, and above-mentioned the second screw equates with the number of the first screw.
Usefulness of the present invention is: changed the fixing position of bolt, prevent that bolt from passing gasket seal, affect the sealing of gasket seal, and the outward flange dish surrounded gasket seal and inner flange, its protruding edge has also served as the effect of outer Sealing.
Description of drawings
Fig. 1 is structural representation of the present invention.
The implication of reference character among the figure:
The 1-inner flange, 2-outward flange dish, 3-gasket seal, 4-bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
Socket flange component as shown in Figure 1 comprises inner flange 1, outward flange dish 2 and the gasket seal 3 between inner flange 1 and outward flange dish 2.Be formed with the edge of projection on the circumference of outward flange dish 2, the diameter of a circle that the inboard, edge surrounds is called the internal diameter of outward flange dish 2, and the diameter of a circle that the outside, edge surrounds is called the external diameter of outward flange dish 2; The external diameter of outward flange dish 2 is greater than the diameter of inner flange 1, and the internal diameter of outward flange dish 2 equals the diameter of inner flange 1, and inner flange 1 is positioned at the edge of outward flange dish 2.The side of inner flange 1 is provided with a plurality of the first screws, and the edge of outward flange dish 2 is provided with second screw corresponding with the first screw.
As a kind of preferred version, the height of edge protuberance is the summation of the thickness of gasket seal 3 and inner flange 1, is convenient to inner flange 1 and sticks into outward flange dish 2 inside.Gasket seal is spiral wound gasket, good seal performance.
For fixedly inner flange and outward flange dish, socket flange component of the present invention also comprises the bolt 4 that passes successively the second screw and the first screw.The internal thread of the outside thread of bolt 4 and the first screw and the second screw coincide.Bolt 4 is hexagon head bolt, and bolt head has cross recess, is convenient to like this construction bolt.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
Claims (6)
1. a socket flange component comprises inner flange, it is characterized in that, also comprises: outward flange dish, gasket seal between above-mentioned inner flange and outward flange dish; Be formed with the edge of projection on the circumference of above-mentioned outward flange dish, the external diameter of above-mentioned outward flange dish is greater than the diameter of above-mentioned inner flange, and the internal diameter of above-mentioned outward flange dish equals the diameter of above-mentioned inner flange, and above-mentioned inner flange is positioned at the edge of above-mentioned outward flange dish; The side of above-mentioned inner flange is provided with a plurality of the first screws, and the edge of above-mentioned outward flange dish is provided with second screw corresponding with above-mentioned the first screw.
