Abstract
The invention provides a pressure-resistant flange sealing structure, and relates to a sealing structure. V-shaped grooves (7) of annular structures are respectively formed in the middle parts of opposite surfaces of flanges (1) of a pipeline A (4) and a pipeline B (8), V-shaped bulges (6) are respectively arranged in the middle parts of the two side surfaces of a sealing ring (5), an elastic steel bar (3) is embedded in the sealing ring arranged between the two V-shaped bulges, the sealing ring is positioned between the flanges of the pipeline A and the pipeline B, the two V-shaped bulges of the sealing ring are positioned in the V-shaped grooves of the two flanges (1), a plurality of screw bolts (11) respectively pass through a plurality of through holes (2) formed in positions, near the outer edge, of the flanges of the pipeline A and the pipeline B and are then tightly locked by screw nuts (10). The pressure-resistant flange sealing structure has the advantages that the two V-shaped bulges of the sealing ring are used for being matched with the V-shaped grooves formed in the opposite surfaces of the two flanges, the elastic steel bar is used for supporting the sealing ring, and the displacement or leakage avoidance after the sealing ring aging is enabled to be avoided.
Description
[technical field]
The present invention relates to a kind of sealing configuration, be specifically related to a kind of Anti-pressure flange sealing structure.
[background technique]
Known, the flange plate being convenient to connect is typically provided with at pipeline joint, sheet type seal ring is utilized between two flange plate, the leakage of anti-fluid is realized by seal ring, for the fluid of conveying, need to impel fluid to flow by pressurization, corresponding pressure can make seal ring occur aging, displacement, and serious meeting causes leakage; So for the ageing-resistant of seal ring with prevent displacement from being the technical barrier of related domain always.
[summary of the invention]
In order to overcome deficiency of the prior art, the invention discloses a kind of Anti-pressure flange sealing structure, utilize two " V " shape projection of seal ring and " V " shape slot fit of two flange plate opposing sides, and elastic steel bar is to the support of seal ring, ensure that seal ring there will not be aging after displacement or leakage.
In order to realize described goal of the invention, the present invention adopts following technology:
A kind of Anti-pressure flange sealing structure, comprise pipeline A, pipeline B, bolt, nut, seal ring and elastic steel bar, be respectively equipped with flange plate at the connecting end of pipeline A and pipeline B, in the middle part of the flange plate opposing side of pipeline A and pipeline B, be respectively equipped with " V " shape groove of loop configuration; Seal ring cross section is rectangle structure, is respectively equipped with " V " shape protruding, is embedded with elastic steel bar in the seal ring between two " V " shape projection in the middle part of the bi-side of seal ring; Seal ring is between the flange plate of pipeline A and pipeline B, wherein two " V " shape projection of seal ring is in " V " shape groove of two flange plate, and many bolts are each passed through after multiple perforation that pipeline A and pipeline B flange plate arrange near outer rim respectively by nut check.
Described Anti-pressure flange sealing structure, the diameter of described elastic steel bar is wider than at least one millimeter of thickness of seal ring.
Described Anti-pressure flange sealing structure, is provided with protruding reinforcing strip in the joint of pipeline A and flange plate, and the joint of described pipeline B and another flange plate is provided with another protruding reinforcing strip.
Owing to have employed technique scheme, the present invention has following beneficial effect:
Anti-pressure flange sealing structure of the present invention, " V " shape groove utilizing pipeline A and pipeline B flange plate opposing side to arrange is stuck in two " V " shape projection of seal ring, when seal ring is subject to manifold pressure impact, be subject to the support of the spacing and elastic steel bar of " V " shape groove, seal ring there will not be aging after displacement or leakage; Sealing effect of the present invention is better, can effectively extend service time of the present invention by elastic steel bar.
[accompanying drawing explanation]
Fig. 1 is assembly structure schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention;
In figure: 1, flange plate; 2, bore a hole; 3, elastic steel bar; 4, pipeline A; 5, seal ring; 6, " V " shape is protruding; 7, " V " shape groove; 8, pipeline B; 9, protruding reinforcing strip; 10, nut; 11, bolt.
[embodiment]
With reference to the following examples, the present invention can be explained in more detail; But it should be noted that the present invention is not limited to following embodiment; Disclose object of the present invention to be intended to protect all changes and improvements in the scope of the invention.
Anti-pressure flange sealing structure by reference to the accompanying drawings described in 1 or 2, comprise pipeline A4, pipeline B8, bolt 11, nut 10, seal ring 5 and elastic steel bar 3, flange plate 1 is respectively equipped with at the connecting end of pipeline A4 and pipeline B8, the joint of pipeline A4 and flange plate 1 is provided with protruding reinforcing strip 9, the joint of described pipeline B8 and another flange plate 1 is provided with another protruding reinforcing strip 9, is respectively equipped with " V " shape groove 7 of loop configuration in the middle part of flange plate 1 opposing side of pipeline A4 and pipeline B8; Seal ring 5 cross section is rectangle structure, " V " shape projection 6 is respectively equipped with in the middle part of the bi-side of seal ring 5, be embedded with elastic steel bar 3 in seal ring 5 between two " V " shape projection 6, the diameter of described elastic steel bar 3 is wider than at least one millimeter of thickness of seal ring 5; Seal ring 5 is between the flange plate 1 of pipeline A4 and pipeline B8, wherein two " V " shape projection 6 of seal ring 5 is in " V " shape groove 7 of two flange plate 1, and many bolts 11 are locked by nut 10 after being each passed through multiple perforation 2 that pipeline A4 and pipeline B8 flange plate 1 arrange near outer rim respectively.
Implement Anti-pressure flange sealing structure of the present invention, during use, between the flange plate 1 seal ring 5 being placed on pipeline A4 and pipeline B8, wherein two " V " shape projection 6 of seal ring 5 puts into " V " shape groove 7 of two flange plate 1 opposing sides, is locked respectively after then use many bolts 11 to be each passed through multiple perforation 2 that pipeline A4 and pipeline B8 flange plate 1 arrange near outer rim by nut 10; Using process is by the interior interruption-forming first sealing of seal ring 5, when pressure is larger, two " V " shape projection 6 of seal ring 5 just can form second strong sealing in two flange plate 1 " V " shape grooves 7, elastic steel bar 3 wherein can control can not be out of shape when seal ring 5 occurs aging, obtains higher Anti-pressure sealing.
Part not in the detailed description of the invention is prior art.
