Abstract
The utility model discloses a sleeve connection flange plate assembly. The sleeve connection flange plate assembly comprises an inner flange plate and is characterized by further comprising an outer flange plate and a sealing gasket which is located between the inner flange plate and the outer flange plate. Protruding edges are formed on the circumference 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, and the inner flange plate is located in the edges of the outer flange plate. A plurality of first screw holes are formed in the side of the inner flange plate, and second screw holes corresponding to the first screw holes are formed in the edges of the outer flange plate. The sleeve connection flange plate assembly has the advantages that the positions where bolts are fixed are changed, the bolts are prevented from penetrating through the sealing gasket to affect the sealing performance of the sealing gasket, the outer flange plate surrounds the sealing gasket and the inner flange plate, and the protruding edges also have the function of an outer layer sealing piece.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is 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 therefore connected is the important parameter characteristic of check flange plate quality, and poor sealing is prone to the phenomenons such as infiltration gas leakage.And two the flange plate circumferential size up and down on existing flange plate equate to only have one deck pad, once the pad wearing and tearing just there will be seepage, sealing effect is poor.
The model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of flange component of good seal performance.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of socket flange component, comprise 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 protruding edge 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.
The summation of the thickness that further, the height of above-mentioned edge protuberance is 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 utility model 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The implication of reference character in 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 utility model is done to concrete introduction.
Socket flange component as shown in Figure 1, comprise inner flange 1, outward flange dish 2 and the gasket seal 3 between inner flange 1 and outward flange dish 2.Be formed with protruding edge 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 summation of the thickness that the height of edge protuberance is gasket seal 3 and inner flange 1, be convenient to inner flange 1 and stick 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 utility model also comprises successively the bolt 4 through 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.
Above demonstration and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
Claims (6)
1. a socket flange component, comprise 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 protruding edge 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.
