Abstract
The invention provides a soft sealing device provided with grooves in butting surfaces and applied to a connecting flange and relates to soft sealing devices. The soft sealing device comprises an outer rubber ring (1), a steel ring (3) and an inner rubber ring (5). The lower surface of the outer rubber ring (1) is provided with an n-shaped groove (2). The upper surface of the inner rubber ring (5) is provided with a U-shaped groove (4). The steel ring (3) is arranged in the U-shaped groove (4) of the inner rubber ring (5). The outer rubber ring (1) is buckled on the inner rubber ring (5). According to the soft sealing device, a conventional seal ring is changed into the outer rubber ring and the inner rubber ring; under the effect of the steel ring, the upper surface of the outer rubber ring and the lower surface of the inner rubber ring are forced to be tightly connected with the connecting flange, and the defect that in the prior art, the seal ring loses the sealing function after corrosion and ageing is effectively overcome.
Description
[technical field]
The present invention relates to a kind of soft seal device, be specifically related to one and be applicable to the reeded soft seal device of adpting flange interface tool.
[background technique]
Known, in the construction and maintenance of product pipeline, need to use and there is higher anti-extension, tension and ageing-resistant soft seal device " seal ring ", seal ring is to use HNBR hydrogenated nitrile-butadiene rubber material to make, wherein seal ring also needs to meet the out-of-flatness of adpting flange joint, existing seal ring is for explosive gasoline or other oil product, not only also very high for weatherability requirement, and needs seal ring to have strictly airtight requirement; Existing 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 invention discloses one and be applicable to the reeded soft seal device of adpting flange interface tool, utilize above rubber outer ring and be connected closely adpting flange with below rubber inner ring, effectively overcome prior art and be corroded the rear aging drawback that loses seal action.
In order to realize described goal of the invention, the present invention adopts following technology:
One is applicable to the reeded soft seal device of adpting flange interface tool, comprise rubber outer ring, steel loop and rubber inner ring, bottom surfaces in rubber outer ring is provided with " ㄇ " shape groove, the upper side of rubber inner ring is provided with " U " shape groove, steel loop is arranged in described rubber inner ring " U " shape groove, and rubber outer ring is buckled on rubber inner ring.
The described reeded soft seal device of adpting flange interface tool that is applicable to, described rubber outer ring and rubber inner ring are HNBR hydrogenated nitrile-butadiene rubber material.
The described reeded soft seal device of adpting flange interface tool that is applicable to, described steel loop is stainless steel ring.
Owing to having adopted technique scheme, the present invention has following beneficial effect:
The reeded soft seal device of adpting flange interface tool that is applicable to of the present invention, be applicable to the reeded soft seal device of adpting flange interface tool, be rubber outer ring, rubber inner ring by changing conventional seal ring, under the effect of steel loop, force above rubber outer ring and be connected closely adpting flange with below rubber inner ring, effectively overcome prior art and be corroded the rear aging drawback that loses seal action; The advantages such as the present invention has good sealing effect, simple in structure, easy installation.

[embodiment]
With reference to the following examples, can explain in more detail the present invention; But it should be noted that the present invention is not limited to following embodiment; Disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention.
Described in 1,2 or 3, be applicable to the reeded soft seal device of adpting flange interface tool by reference to the accompanying drawings, comprise rubber outer ring 1, steel loop 3 and rubber inner ring 5, bottom surfaces in rubber outer ring 1 is provided with " ㄇ " shape groove 2, the upper side of rubber inner ring 5 is provided with " U " shape groove 4, steel loop 3 is arranged in described rubber inner ring 5 " U " shape groove 4, and rubber outer ring 1 is buckled on rubber inner ring 5; Wherein said rubber outer ring 1 and rubber inner ring 5 are HNBR hydrogenated nitrile-butadiene rubber material; Described steel loop 3 is stainless steel ring.
Implement the reeded soft seal device of adpting flange interface tool that is applicable to of the present invention
,by reference to the accompanying drawings 1,2,3 or 4, utilize HNBR hydrogenated nitrile-butadiene rubber material to make rubber outer ring 1 and rubber inner ring 5, guaranteed weatherability when the present invention uses, while forming rubber outer ring 1 and the interior side contacts oil product of rubber inner ring 5 by stainless steel steel loop 3, outside is isolated, and has obtained dual guarantee, when use, the present invention after combination being placed on to pipeline 7 locates with the groove " the step place that adpting flange 9 and another adpting flange 10 arrange near inner orifice place in docking " in another pipeline 8 joints, use bolt 6 that another adpting flange 10 of the adpting flange of pipeline 79 and another pipeline 8 is connected, at this moment steel loop 3 is stressed, make rubber outer ring 1, rubber inner ring 5 forces above rubber outer ring 1 and the groove that is connected closely adpting flange 9 below rubber inner ring 5 under the effect of steel loop 3, namely steel loop 3 makes rubber outer ring 1, rubber inner ring 5 outer rim places form isolation, the rubber outer ring 1 of isolation, rubber inner ring 5 outer rims are obtained the airtight of another time.
Part not in the detailed description of the invention is prior art.
