Abstract
The invention discloses a novel flange plate component. The novel flange plate component comprises a first flange plate, a second flange plate and a sealing ring located between the first flange plate and the second flange plate, wherein a convex step structure is formed in the circumference of the second flange plate; the outer diameter of the second flange plate is equal to the diameter of the first flange plate; the inner diameter of the second flange plate is smaller than the diameter of the first flange plate; a second screw hole is formed in the step structure of the second flange plate; a first screw hole matching with the second screw hole is formed in the circumference of the first flange. The novel flange plate component has the beneficial effects of changing a fixed position of a bolt, preventing the bolt from penetrating the sealing ring to affect the sealing performance of a sealing pad, and also enabling the convex edge of the outer flange to act as an outer sealing member. The sealing ring coated with vacuum silicone grease has a better sealing performance.
Description
Technical field
The present invention relates to a kind of mechanical fastener, be specifically related to a kind of Novel ring flange assembly.
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 seal ring, and 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 Novel ring flange assembly comprises the first flange plate, it is characterized in that, also comprises: the second flange plate, the seal ring between above-mentioned the first flange plate and the second flange plate; Be formed with the ledge structure of projection on above-mentioned the second flange plate circumference, the external diameter of above-mentioned the second flange plate equals the diameter of above-mentioned the first flange plate, and the internal diameter of above-mentioned the second flange plate is less than the diameter of above-mentioned the first flange plate; The ledge structure of above-mentioned the second flange plate is provided with the second screw, is formed with the first screw that cooperates with above-mentioned the second screw on the circumference of above-mentioned the first flange plate; Above-mentioned the first screw is slotted eye, and above-mentioned the second screw is through hole.
Further, the height of above-mentioned ledge structure projection equals the thickness of seal ring.
Further, above-mentioned seal ring is spiral wound gasket; Above-mentioned seal ring periphery also scribbles one deck vacuum silicone grease.
Further, also comprise the bolt that passes successively above-mentioned the second screw and the first screw.
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, prevented that bolt from passing seal ring, affect the sealing of gasket seal, and the edge of outward flange projection has also served as the effect of outer Sealing.The sealing ring tightness that scribbles the vacuum silicone grease is better.
Description of drawings
Fig. 1 is structural representation of the present invention.
The implication of reference character among the figure:
1-the first flange plate, 2-the second flange plate, 3-seal ring, 4-bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
A kind of Novel ring flange assembly as shown in Figure 1 comprises the first flange plate 1, the second flange plate 2, the seal ring 3 between the first flange plate 1 and the second flange plate 2; Be formed with the ledge structure of projection on the second flange plate 2 circumference, the diameter of a circle that we surround the ledge structure outside becomes the external diameter of the second flange plate 2, the diameter of a circle that the ledge structure inboard surrounds becomes the internal diameter of the second flange plate 2, the external diameter of the second flange plate 2 equals the diameter of the first flange plate 1, and the internal diameter of the second flange plate 2 is less than the diameter of the first flange plate 1; The ledge structure of the second flange plate 2 is provided with the second screw, is formed with the first screw that cooperates with the second screw on the circumference of the first flange plate 1.The second screw is through hole, and the first screw is slotted eye.
In order to increase the sealing of flange plate, the height of ledge structure projection equals the thickness of seal ring.Seal ring 3 is spiral wound gasket, and seal ring 3 peripheries also scribble one deck vacuum silicone grease.
Novel ring flange assembly of the present invention also comprises the bolt 4 that passes successively the second screw and the first screw, and bolt 4 is used for the fixed flange assembly.The internal thread of the outside thread of bolt 4 and the first screw and the second screw coincide.In order to guarantee the fixed effect of bolt 4, the number of the first screw is at least 4, and is evenly distributed on the circumference of the second flange plate 2, and the second screw equates with the number of the first screw.
Above demonstration 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.
