Abstract
The utility model discloses a flange pair. The flange pair comprises a sealing part and two flange plates. The flange pair is characterized in that sealing grooves are formed in the flange plates, the sealing part can be placed into the sealing grooves, fixing lug edges are formed at the peripheries of the circumferences of the flange plates respectively, threaded holes are formed in the fixing lug edges respectively, and the sealing part is a sealing circular ring. The flange pair has the advantages that due to the fact that the shape of the sealing part is changed, the sealing part can have the radial self-tightness effect, the contact area of the sealing part is increased, and sealing performance is improved.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is 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 therefore connected is the important parameter characteristic of check flange quality, between flange and flange, is provided with seal washer, 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, sealing effect is poor.
Summary of the invention
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of flange pair of good seal performance.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of flange pair, comprise a Sealing and two flange plates, it is characterized in that, above-mentioned flange plate inside is provided with for placing the seal groove of above-mentioned Sealing, and above-mentioned flange plate periphery is formed with fixes 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 triangle that the cross section of above-mentioned seal groove is unfilled corner, two identical seal groove groups of cross section that above-mentioned seal groove is spliced into 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 utility model is: change the shape of Sealing, make Sealing have radially from closely effect, increased the area of contact of Sealing, improve sealability.
The accompanying drawing explanation
Fig. 1 is the sectional view of flange plate of the present utility model;
Fig. 2 is the sectional view after two flange plates shown in Fig. 1 and Sealing assembling.
The implication of reference character in 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 utility model is done to concrete introduction.
A kind of flange pair as shown in Figure 1 and Figure 2, comprise a Sealing 2 and two flange plates 1, and flange plate 1 inside is provided with the seal groove 3 for 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 triangle that the cross section of seal groove 3 is 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 a cross section and the identical seal groove group of Sealing 2 cross sections, while 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, by bolt 4, inserts in screws 102 two flange plates are linked together.
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)
