Abstract
The invention discloses a flange sealing device, comprising a connecting flange body; an epoxy primer coating is arranged on a connecting flange surface; the joints of a connecting flange are connected by glue injection; an external ring and an internal ring are arranged on the connecting flange body; an external ring sealing groove is formed on the external ring; an internal ring sealing groove is formed on the internal ring; sealing rings matching with each other are embedded in the external ring sealing groove and the internal ring sealing groove; and an adjusting handwheel is arranged at the edge of the connecting flange. Compared with the prior art, the flange surface is coated with an epoxy primer, so that the flange surface is improved; meanwhile, the glue injection is adopted and the sealing rings are arranged; the sealing rings are arranged in two sealing grooves; moreover, the air-tightness can be adjusted freely by rotating the handwheel manually, and the flange sealing device is flexible and accurate to use; the air leakage of the flange surface is improved greatly, so that the air-tightness of connecting pipelines by means of flanges is ensured and the influence caused by the leakage of materials is avoided.
Description
Technical field
The present invention relates to a kind of sealing configuration, particularly a kind of flange sealer.
Background technique
Flange is again flange plate or bead, is to make the interconnective part of pipeline, is connected to pipe end.Perforation on flange, bolt makes two flanges be close to.With liner containment between existing flange, great majority adopt the sealing of General Purpose Rubber circle, are applied in the corrosion that petroleum chemical industry is easily subject to material, always lose sealing effect, cause pipe leakage, cause material loss in pipeline, pollute factory building, and cause economic loss.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of flange sealer, can solve the problem completely.
The technological scheme solved the problems of the technologies described above is as follows:
A kind of flange sealer, comprise adpting flange body, described connecting flange faces is provided with epoxy primer coating, the joint of adpting flange is connected by injecting glue, described adpting flange body has outer ring and inner ring, and described outer ring is provided with outer ring seal groove, and described inner ring is provided with inner ring seal groove, all be inlaid with the seal ring of coupling in described outer ring seal groove and inner ring seal groove, the edge of adpting flange is provided with adjusting handle.
Further, described adjusting handle is connected with threaded connector.
Further, the preferred resistant material of described seal ring, in order to cost-saving, also can adopt rubber seal in suitable pipeline.
Structure of the present invention is simple, compared with prior art, flanged surface adopts epoxy primer application, improve flanged surface, injecting glue adds seal ring simultaneously, all adopts seal ring in two circle seal grooves, and can by the method free adjustment tightness of artificial rotation hand wheel, use flexibly precisely, improve flanged surface gas leakage situation greatly thus ensure that the sealing of Flange joint pipeline, avoiding the impact that the leakage because of material causes.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure: 1 is adpting flange body, 2 is outer ring, and 3 is inner ring, and 21 is outer ring seal groove, and 31 is inner ring seal groove, and 4 is seal ring, and 5 is adjusting handle.
Embodiment
A kind of flange sealer, comprise adpting flange body 1, described connecting flange faces is provided with epoxy primer coating, the joint of adpting flange is connected by injecting glue, described adpting flange body 1 has outer ring 2 and inner ring 3, described outer ring 2 is provided with outer ring seal groove 21, described inner ring 3 is provided with inner ring seal groove 31, the seal ring 4 of coupling is all inlaid with in described outer ring seal groove 21 and inner ring seal groove 31, the edge of adpting flange is provided with adjusting handle 5, described adjusting handle 5 is connected with threaded connector, described seal ring 4 is made up of resistant material or General Purpose Rubber.
Structure of the present invention is simple, compared with prior art, flanged surface adopts epoxy primer application, improve flanged surface, injecting glue adds seal ring simultaneously, all adopts seal ring in two circle seal grooves, and can by the method free adjustment tightness of artificial rotation hand wheel, use flexibly precisely, improve flanged surface gas leakage situation greatly thus ensure that the sealing of Flange joint pipeline, avoiding the impact that the leakage because of material causes.
