Abstract
The invention provides a flange and a sealing ring structure with multiplex pressure-resistant structures, and relates to a pipeline sealing structure. Annular grooves (8) are respectively formed in opposite surfaces of flanges (7) of a pipeline A (3) and a pipeline B (4); the inner surface of a sealing ring (5) is provided with an annular V-shaped groove (6); the sealing ring is arranged in a rectangular hole formed by two grooves formed after the flange of the pipeline A is buckled with the flange of the pipeline B; the V-shaped groove of the sealing ring corresponds to the inner side seam of the rectangular hole formed after the two flanges are buckled, and a plurality of screw bolts (2) pass through the flanges of the pipeline A and the pipeline B to approach to a through hole (10) formed in the outer edge, and are then respectively and tightly locked by screw nuts (1). The flange and sealing ring structure have the advantages that the multiplex pressure resistance is formed by using the two flanges, the sealing ring body and the V-shaped groove of the sealing ring positioned in the two annular grooves, so the displacement phenomenon after the sealing ring aging is effectively prevented, and the leakage occurrence is prevented.
Description
[technical field]
The present invention relates to a kind of pipeline sealing structure, be specifically related to a kind of flange plate and the ring structure with multiple compression-resistant 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 flange plate and the ring structure with multiple compression-resistant structure, " V " shape groove, seal ring body and two flange plate being in seal ring in two annular grooves are utilized to form multiple resistance to compression, effective offset phenomena having taken precautions against the aging rear appearance of seal ring, has taken precautions against the generation revealed.
In order to realize described goal of the invention, the present invention adopts following technology:
A kind of flange plate and ring structure with multiple compression-resistant structure, comprise pipeline A, pipeline B, seal ring, screw bolt and nut, be respectively equipped with flange plate at the connecting end of pipeline A and pipeline B, the flange plate opposing side of pipeline A and pipeline B is respectively equipped with annular groove; The inner face of seal ring is provided with " V " shape groove of annular; The flange plate of flange plate and pipeline B that seal ring is arranged on pipeline A fastens in the oblong aperture of rear two grooves formation, the gap, inner side of oblong aperture after the corresponding two flange plate fastenings of " V " shape groove of described seal ring; Locked by nut respectively after the perforation that multiple bolt is arranged near outer rim through pipeline A and pipeline B flange plate.
The described flange plate with multiple compression-resistant structure and ring structure, described seal ring is tabular seal ring.
The described flange plate with multiple compression-resistant structure and ring structure, the bi-side of seal ring are respectively equipped with at least one harmomegathus groove.
Owing to have employed technique scheme, the present invention has following beneficial effect:
Flange plate and the ring structure with multiple compression-resistant structure of the present invention, by arranging annular groove respectively on the flange plate of pipeline A and pipeline B, be in " V " shape groove of seal ring in two annular grooves, seal ring body and two flange plate and form multiple resistance to compression, effective offset phenomena having taken precautions against the aging rear appearance of seal ring, has taken precautions against the generation revealed; Compression strength of structure of the present invention is stronger.

Fig. 3 is ring structure schematic diagram of the present invention;
In figure: 1, nut; 2, bolt; 3, pipeline A; 4, pipeline B; 5, seal ring; 6, " V " shape groove; 7, flange plate; 8, groove; 9, harmomegathus groove; 10, bore a hole.
[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.
The flange plate with multiple compression-resistant structure by reference to the accompanying drawings described in 1,2 or 3 and ring structure, comprise pipeline A3, pipeline B4, seal ring 5, bolt 2 and nut 1, be respectively equipped with flange plate 7 at the connecting end of pipeline A3 and pipeline B4, flange plate 7 opposing side of pipeline A3 and pipeline B4 is respectively equipped with annular groove 8; The inner face of seal ring 5 is provided with " V " shape groove 6 of annular, and the bi-side of seal ring 5 are respectively equipped with at least one harmomegathus groove 9; The flange plate 7 of flange plate 7 and pipeline B4 that tabular seal ring 5 is arranged on pipeline A3 fastens in the oblong aperture of rear two grooves 8 formation, and corresponding two flange plate 7 of " V " shape groove 6 of described seal ring 5 fasten the gap, inner side of rear oblong aperture; Locked by nut 1 respectively after the perforation 10 that multiple bolt 2 is arranged near outer rim through pipeline A3 and pipeline B4 flange plate 7.
Implementing flange plate and the ring structure with multiple compression-resistant structure of the present invention, is the annular groove 8 that the seal ring 5 of platy structure puts on the pipeline A3 of fastening and pipeline B4 flange plate 7 by section; Many bolts 2 are used to be locked by nut 1 after outer rim is multiple perforation 10 through pipeline A3 and pipeline B4 flange plate 7, at this moment the oblong aperture interference fit that just formed with two annular grooves 8 of seal ring 5; During use, after passing into liquid in the duct, during the flange plate 7 that liquid docks through piping A3 and pipeline B4, first the liquid being entered annular groove 8 by two flange plate 7 can form stop in seal ring 5 " V " shape groove 6, at this moment the inner face of seal ring 5 is subject to the pressure of collected liquid in " V " shape groove 6, force the secondary pressure that seal ring 5 inner face of " V " shape groove 6 both sides obtains, namely seal ring 5 inner face both sides can be attached on two annular grooves 8 more closely; The interference fit of seal ring 5 of the present invention and two annular grooves 8 arranges and liquid also can be made cannot to reveal by being formed between seal ring 5 and annular groove 8; The present invention by arranging annular groove 8 respectively on the flange plate 7 of pipeline A3 and pipeline B4, be in " V " shape groove 6 of seal ring 5 in two annular grooves 8, seal ring 5 body and two flange plate 7 and form multiple resistance to compression, effective offset phenomena having taken precautions against the aging rear appearance of seal ring 5, has taken precautions against the generation revealed.
Part not in the detailed description of the invention is prior art.
