Description

A kind of high-pressure-resistant sealed circle

[technical field]

The utility model relates to a kind of seal arrangement, is specifically related to a kind of high-pressure-resistant sealed circle.

[background technique]

Known, what in conventional fluid pipeline interface, use is that annular seal ring " is also O shape circle ", this airtight requirement that can meet water or other liquid medium, but higher for the requirement of pipe joint " adpting flange place " in chemical industry, especially for explosive gasoline or other oil product, not only also very high for weatherability requirement, and need seal ring to there is strictly airtight requirement; Existing O shape rubber ring in use, is subject to the smooth situation impact of workmanship, rigidity of flange and the flange interface of bolts and nuts, loses due obturation effect after stressed elongation.

[summary of the invention]

In order to overcome deficiency of the prior art, the utility model discloses a kind of high-pressure-resistant sealed circle, by block the outer rim of interior rubber plate in top steel loop, middle part steel loop and bottom steel loop inner side, protrude bar, by interior rubber plate, form tight sealing effect, effectively overcome the drawback of the easy aging distortion of existing rubber ring, displacement.

In order to realize described invention, the utility model adopts following technology:

A kind of high-pressure-resistant sealed circle, comprise top steel loop, rubber weather strip and bottom steel loop, the hole that is evenly provided with a plurality of mutual correspondences at the ring body middle part of top steel loop and bottom steel loop, the close inner ring surface place of described top steel loop and bottom steel loop opposing side is respectively equipped with groove; Described rubber weather strip comprises that interior rubber plate, outer rim protrude bar, and interior rubber plate is square structure, at the interior rubber plate outer edge surface middle part of described square structure, be provided with around outer rim protrude bar; The outer rim of rubber weather strip is protruded bar and is clamped in the groove of top steel loop, bottom steel loop opposing side, and wherein said outer rim is protruded the interior rubber plate height of bar inner side a little more than the stack height of top steel loop and bottom steel loop.

Described high-pressure-resistant sealed circle, between top steel loop and bottom steel loop, be provided with middle part steel loop, the groove inner side of the outer edge surface of described middle part steel loop and top steel loop and bottom steel loop opposing side maintains an equal level, namely the outer rim of interior rubber plate outside is protruded bar outer edge surface and is withstood on the outer edge surface of described middle part steel loop, and described middle part steel loop is provided with and top steel loop and bottom steel loop equal number and corresponding hole mutually.

Described high-pressure-resistant sealed circle, described outer rim is protruded the interior rubber plate height of bar inner side a little more than the stack height of top steel loop, middle part steel loop and bottom steel loop.

Owing to having adopted technique scheme, the utlity model has following beneficial effect:

High-pressure-resistant sealed circle described in the utility model, the logical groove by top steel loop and bottom steel loop blocks the outer rim protrusion bar that described interior rubber plate outer rim arranges, middle part steel loop further withstands described outer rim and protrudes bar, obtained the sealing effect of interior rubber plate, acting in conjunction due to above-mentioned top steel loop, middle part steel loop and bottom steel loop, can make interior rubber plate when obtaining sealing effect, realize the effect that the interior aging distortion of rubber plate of strick precaution or displacement cause sealing effect to lose; The utility model is simple in structure, and sealing effect is obviously better than prior art.

Fig. 1 is perspective view of the present utility model;

Fig. 2 is structural representation of the present utility model;

In figure: 1, hole; 2, top steel loop; 3, middle part steel loop; 4, interior rubber plate; 5, outer rim is protruded and is changed; 6, bottom steel loop; 7, groove.

[embodiment]

With reference to the following examples, can explain in more detail the utility model; But it should be noted that the utility model is not limited to following embodiment; Open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model.

High-pressure-resistant sealed circle described in 1 or 2 by reference to the accompanying drawings, comprise top steel loop 2, rubber weather strip and bottom steel loop 6, the hole 1 that is evenly provided with a plurality of mutual correspondences at the ring body middle part of top steel loop 2 and bottom steel loop 6, the close inner ring surface place of described top steel loop 2 and bottom steel loop 6 opposing sides is respectively equipped with groove 7; Described rubber weather strip comprises that interior rubber plate 4, outer rim protrude bar 5, and interior rubber plate 4 be square structure, at the interior rubber plate 4 outer edge surfaces middle parts of described square structure, be provided with around outer rim protrusion bar 5; The outer rim of rubber weather strip is protruded bar 5 and is clamped in the groove 7 of top steel loop 2, bottom steel loop 6 opposing sides, and wherein said outer rim is protruded interior rubber plate 4 height of bar 5 inner sides a little more than the stack height of top steel loop 2 and bottom steel loop 6; Or steel loop 3 in the middle part of being provided with between top steel loop 2 and bottom steel loop 6, groove 7 inner sides of the outer edge surface of described middle part steel loop 3 and top steel loop 2 and bottom steel loop opposing side maintain an equal level, namely the outer rim of interior rubber plate 4 outsides is protruded bar 5 outer edge surfaces and is withstood on the outer edge surface of described middle part steel loop 3, and described middle part steel loop 3 is provided with and top steel loop 2 and bottom steel loop 6 equal number and corresponding hole 1 mutually; Wherein said outer rim is protruded interior rubber plate 4 height of bar 5 inner sides a little more than the stack height of top steel loop 2, middle part steel loop 3 and bottom steel loop 6.
