Description
Technical field
The present invention relates to flange field, specifically a kind of vacuum protection formula flange connector.
Background technology
Flange (Flange), again call orchid flange or bead.Flange is interconnective part between pipe and pipe, for the connection between pipe end；Also there is the flange that the equipment that is used in is imported and exported, for the connection between two equipment, such as reductor flange.Flange joint or bump joint, refer to and be connected with each other the releasable connection as one group of combined sealing structure by flange, pad and bolt three.Pipe flange means the flange of pipe arrangement in plumbing installation, is used on equipment to mean the import and export flange of equipment.Perforation on flange, bolt makes two flanges be close to.Seal with liner between flange.Flange divides threaded (screwed connection) flange, welded flange and clip flange.Flange is all use in pairs, and low pressure pipeline can use wire connection flange, the use welded flange of four kilograms of pressure above.Plus sealing gasket between two panels ring flange, then fasten with bolt.The flange thickness of different pressures is different, and the bolt that they use is also different.Water pump and valve, when connecting with pipeline, the local of these equipment facilities, also make corresponding flange shape, also referred to as Flange joint.Every union piece making at two planar perimeter to be connected with simultaneously closing, is generally referred to as " flange ".
In the producing continuously of modern industry flange by dielectric corrosion, wash away, temperature, pressure, the factor such as vibrations impact, error due to sealing surface processing dimension, aging and the installation of potted component fastens the reasons such as improper, and also probably due to the moisture in extraneous air causes that flange connections generation electrochemical corrosion destroys the compactness of flange connector, inevitably cause the seepage of flange.If flange leakage problems can not be administered in time, under the washing away of medium, meeting makes seepage expand rapidly, causes the loss of material, the destruction of production environment, causes that enterprise shuts down and stops production, causes huge economic loss.If poisonous and harmful, inflammable and explosive dielectric leakage, it is also possible to cause the major accidents such as poisoning, the fire explosion of personnel.
Summary of the invention
For the problems of the prior art, the invention provides a kind of vacuum protection formula flange connector, it enables to install between flange more fasten, it is to avoid flange is subject to the erosion of rainwater and dust, and slow down the electrochemistry that electrochemistry flange is subject to and pollute.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vacuum protection formula flange connector, including upper flange, lower flange, sealing ring, contiguous block and preventer.
Described upper flange is provided with an annular upper flange and No. two upper flanges；A described upper flange is provided with six bolt holes, and a described upper flange periphery is provided with an extra screw thread；No. two described upper flanges are positioned at above a upper flange；
Described lower flange is provided with an annular lower flange and No. two lower flanges；A described lower flange is provided with six bolt holes, and a described lower flange periphery is provided with two extra screw threads；No. two described lower flanges are positioned at below a lower flange；
Described upper flange is connected by six roots of sensation bolt with lower flange, and is provided with sealing ring between upper flange and lower flange, and described sealing ring is quality of rubber materials；
Described contiguous block be annular, described contiguous block inwall is provided with female thread, described female thread can respectively with an extra screw thread and two extra threaded engagement.
During work, first contiguous block can be threadeded with lower flange, then upper flange is threadeded with contiguous block, and upper flange is connected with lower flange bolt, sealing ring is between upper flange and lower flange, and such design makes to be connected between upper flange with lower flange more to fasten.
Described preventer includes protective cover, the cyclic spring rubber base at the upper and lower two ends that are positioned at protective cover and sealing gasket；
Described protective cover is quality of rubber materials, and protective cover is hollow revolving body, and described protective cover side is provided with air entry, and air entry place is provided with vent plug；Described rubber base includes the seat of honour and lower seat, and the described seat of honour and protective cover upper end are fixedly connected with, and described lower seat and protective cover lower end are fixedly connected with；The described seat of honour is dismountable to be bolted on No. two upper flanges, and described lower seat is dismountable to be bolted on No. two lower flanges；It is mounted on sealing gasket between the described seat of honour and No. two upper flanges and between lower seat and No. two lower flanges；Before upper flange is not connected with lower flange; protective cover upper end can be fixed on upper flange by the seat of honour; after upper flange connects with lower flange; then by lower seat, protective cover lower end is fixed on lower flange; thus protective cover can be good at protection flange connector, meanwhile, air entry can be passed through by the air sucking-off in the cavity between protective cover and flange connector; make to be approximately in protective cover vacuum environment, thus the electrochemistry slowing down flange connector is polluted.
The invention has the beneficial effects as follows:
(1) design of contiguous block of the present invention so that be not only connected by bolt between upper flange with lower flange, also examines contiguous block and carries out dual connection, so that the connection tightness of the present invention is higher；
(2) present invention design has protective cover; protective cover can adequately protect the flange connections of the present invention; make the present invention will not be subject to the erosion of rainwater and dust etc.; simultaneously; the cavity in protective cover can be made to be approximately vacuum environment by the air in extraction protective cover, and then slow down the electrochemical corrosion of the present invention.
