Abstract
The invention discloses a flange pair which comprises a sealing element and two flange pieces. The flange pair is characterized in that sealing grooves for containing the sealing element are formed in the flange pieces, fixing lug edges are formed on the peripheries of the flange pieces and provided with screw holes, and the sealing element is a sealing ring. The flange pair has the advantages that the shape of the sealing element is changed so that the sealing element has a radial self-sealing function, the contact area of the sealing element is increased, and the sealing performance is improved.
Description
Technical field
The present invention relates to a kind of mechanical fastener, be specifically related to a kind of flange pair.
Background technique
Flange 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 quality, is provided with seal washer between flange and the flange, and the poor sealing of seal washer is prone to the phenomenons such as infiltration gas leakage.And mostly the seal washer of existing flange is the annulus pad of even thickness, and sealing effect is relatively poor.
Summary of the invention
Be to solve the deficiencies in the prior art, the object of the present invention is to provide a kind of flange pair of good seal performance.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of flange pair comprises a Sealing and two flange plates, it is characterized in that, above-mentioned flange plate inside is provided be used to the seal groove of placing above-mentioned Sealing, above-mentioned flange plate periphery be formed with fixing in one's ear, the above-mentioned fixing screw that is provided with in one's ear; Above-mentioned Sealing is sealed circular ring.
Further, the cross section of above-mentioned Sealing is the unfilled corner rhombus, wherein one of the unfilled corner inside facing to above-mentioned Sealing.
Further, the cross section of above-mentioned seal groove is the triangle of unfilled corner, and two above-mentioned seal grooves are spliced into the identical seal groove group of cross section of a cross section and above-mentioned Sealing.
Further, above-mentioned Sealing is the metal ring packing ring.
Further, the quantity of above-mentioned screw is 4 or 8, and is evenly distributed in above-mentioned fixing go up in one's ear; Above-mentioned screw is tapped through hole.
Usefulness of the present invention is: change the shape of Sealing, so that Sealing has radially from closely effect, increased the area of contact of Sealing, improve sealability.
Description of drawings
Fig. 1 is the sectional view of flange plate of the present invention;
Fig. 2 is the sectional view after two flange plates shown in Figure 1 and the Sealing assembling.
The implication of reference character among the figure:
The 1-flange plate, 101-is fixing in one's ear, 102-screw, 2-Sealing, 3-seal groove, 4-bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
A kind of flange as shown in Figure 1 and Figure 2 pair comprises a Sealing 2 and two flange plates 1, and flange plate 1 inside is provided with for the seal groove 3 of placing Sealing, and it is fixing in one's ear 101 that flange plate 1 periphery is formed with, and fixingly 101 is provided with screw 102 in one's ear; Sealing 2 is sealed circular ring.The cross section of Sealing 2 is that the unfilled corner rhombus (clipped by an angle that is rhombus, form an irregular pentagon), the inside towards Sealing 2 of unfilled corner wherein, Sealing 2 contacts with the center face of flange plate like this, and Sealing 2 upwards forms the gradient one on the other in the footpath of flange plate 1, guarantees the sealing of flange arrangement.
The cross section of seal groove 3 is that the triangle of unfilled corner (is that triangle is clipped an angle, form an irregular quadrilateral), the seal groove 3 of two flange plates 1 is spliced into the seal groove group that a cross section and Sealing 2 cross sections coincide, when connecting like this, Sealing 2 can be stuck in two seal grooves 3 easily.Sealing 1 is the metal ring packing ring, has radially from closely effect.
In order closely to fix two flange plates 1, screw 102 is tapped through hole, and the quantity of screw 102 is 4 or 8, and is evenly distributed in fixingly in one's ear on 101, inserts in the screws 102 by bolt 4 two flange plates are linked together.
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.
Claims (6)
1. a flange pair comprises a Sealing and two flange plates, it is characterized in that, above-mentioned flange plate inside is provided be used to the seal groove of placing above-mentioned Sealing, above-mentioned flange plate periphery be formed with fixing in one's ear, the above-mentioned fixing screw that is provided with in one's ear; Above-mentioned Sealing is sealed circular ring.
