Abstract
The invention relates to the field of high temperature resistant insulating flange, in particular to a combined flange structure. The combined flange structure is resistant to high temperature. The combined flange structure comprises an upper flange plate and a lower flange plate, an insulating block is arranged between the upper flange plate and the lower flange plate, an insulating block through hole is formed in the center of the insulating block, an upper flange plate fixing hole is formed in the face of the upper flange plate, a lower flange plate fixing hole is formed in the face of the lower flange plate, an insulating block fixing hole is formed in the insulating block, and a fixing bolt penetrates through the upper flange fixing hole, the lower flange fixing hole and the insulating block fixing hole to fix and seal the upper flange plate, the insulating block and the lower flange plate. Due to the fact that the insulating block is additionally arranged between the upper flange plate and the lower flange plate, damage to the combined flange structure caused by high temperature can be effectively obstructed, and the high temperature resistance of the combined flange structure is greatly improved. The combined flange structure is particularly suitable for being used in a high-temperature environment.
Description
Technical field
The present invention relates to high-temperature insulation flange field, especially a kind of Ifold flange structure.
Background technique
Electric arc furnaces is in energising smelting process, and because electrode is in holding state tightly, the object that insulate between newspaper binder oil cylinder oil pipe and conductive cross arm should bear 150 ℃ of high temperature and 8MPa hydraulic system pressure, also will when liquid is flowed through, ensure insulation effect simultaneously; Used insulation object due to structure and material problem in the past, often, because insulating material can not bear hydraulic system pressure layering, oil impregnate, caused producing arc, change density greatly, expend time in morely, affect rhythm of production.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of resistant to elevated temperatures Ifold flange structure.
The technical solution adopted for the present invention to solve the technical problems is: Ifold flange structure, comprise upper flange plate and lower flange, between described upper flange plate and lower flange, be provided with collets, described collets center is provided with collets through hole, in the card of upper flange plate, be provided with upper flange plate fixed hole, in the card of lower flange, be provided with lower flange fixed hole, on collets, be provided with collets fixed hole, fixing bolt is through described upper flange plate fixed hole, lower flange fixed hole and collets fixed hole are by upper flange plate, collets and lower flange fixing seal.
Further, on the interface of upper flange plate and collets, be provided with upper flange plate seal groove, in described upper flange plate seal groove, be provided with seal ring.
Further, on the interface of lower flange and collets, be provided with lower flange seal groove, in described upper flange plate seal groove, be provided with seal ring.
Further, the material of collets is teflon.
The invention has the beneficial effects as follows: by set up collets between upper flange plate and lower flange, can effectively block high temperature to Ifold flange structural damage, greatly improve the heat-resisting ability of Ifold flange structure.Because fixing bolt passes described upper flange plate fixed hole, lower flange fixed hole and collets fixed hole by upper flange plate, collets and lower flange fixing seal, the present invention not only can play sealing and the linkage function of conventional combination flange arrangement, is more specifically adapted at using under the environment of high temperature.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is upper flange plate schematic diagram of the present invention.
Fig. 3 is lower flange schematic diagram of the present invention.
Fig. 4 is collets schematic diagram of the present invention.
In figure, be labeled as: upper flange plate 1, upper flange plate seal groove 11, upper flange plate through hole 12, upper flange plate fixed hole 13, upper flange plate threaded end 14, lower flange 2, lower flange seal groove 21, lower flange through hole 22, lower flange fixed hole 23, lower flange threaded end 24, lower flange bare terminal end 25, collets 3, collets surface of contact 31, collets through hole 32, collets fixed hole 33.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As Fig. 1, Fig. 2, Fig. 3, Ifold flange structure shown in Fig. 4, comprise upper flange plate 1 and lower flange 2, between described upper flange plate 1 and lower flange 2, be provided with collets 3, described collets 3 centers are provided with collets through hole 32, in the card of upper flange plate 1, be provided with upper flange plate fixed hole 13, in the card of lower flange 2, be provided with lower flange fixed hole 23, on collets 3, be provided with collets fixed hole 33, fixing bolt is through described upper flange plate fixed hole 13, lower flange fixed hole 23 and collets fixed hole 33 are by upper flange plate 1, collets 3 and lower flange 2 fixing seals.
For upper flange plate 1, its structure is card and the upper flange plate through hole 12 that structure of conventional flange dish has upper flange plate 1, and upper flange plate threaded end 14 is for being fixed to equipment; For lower flange 2, its structure has card and the lower flange through hole 22 of lower flange 2.Wherein upper flange plate through hole 12, collets through hole 32 and lower flange through hole 22 are a cavity.
Fixing bolt by upper flange plate 1, collets 3 and lower flange 2 fixing seals, can allow the card of upper flange plate 1 and the card of lower flange 2 and collets surface of contact 31 fit tightly through described upper flange plate fixed hole 13, lower flange fixed hole 23 and collets fixed hole 33.Because collets 3 are arranged between upper flange plate 1 and lower flange 2, thus can well block the transmission of high temperature, thus good protective material.
In order to make sealing effect better, can select such scheme: on the interface of upper flange plate 1 and collets 3, be provided with upper flange plate seal groove 11, in described upper flange plate seal groove 11, be provided with seal ring.The seal ring of setting up can well improve sealing.Thought based on same also can be provided with lower flange seal groove 21 on the interface of lower flange 2 and collets 3, in described upper flange plate seal groove 21, is provided with seal ring.Can strengthen sealing effect equally.
For the high-temperature stability of reinforced insulation piece 3, the material that can select collets 3 is teflon.The effect that not only has isolated heat to transmit with the collets 3 that teflon is made, can also the fine function that plays sealing, is the preferred material of collets 3.
