Technical field
The present invention relates to flange fields, specifically a kind of vacuum protection formula flange connector.
Background technology
Flange (Flange), is called flange flange disk or bead.Flange is the part being connected with each other between pipe and pipe,
For the connection between pipe end；Also have with the flange imported and exported in equipment, for the connection between two equipment, such as speed reducer
Flange.Flanged joint or bump joint refer to be connected with each other as one group of combined sealing structure by flange, gasket and bolt three
Releasable connection.Pipe flange is meant with effective flange in plumbing installation, with the inlet and outlet flange that equipment is meant in equipment.
Perforation on flange, bolt are close to two flanges.With pad sealing between flange.Flange point threaded connection (screwed connection) flange,
Welded flange and clip flange.Flange all uses in pairs, and low pressure pipeline can use silk acting flange, four kilograms of pressure above
Use welded flange.Plus gasket between two panels ring flange, then fastened with bolt.The flange thickness of different pressures is not
Together, the bolt that they are used is also different.Water pump and valve, when being connected with pipeline, phase is also made in the part of these equipment facilities
Corresponding flange shape, also referred to as flanged joint.It is every to use the connection zero for being bolted while closing in two planar perimeters
Part, generally referred to as " flange ".
In the continuous production of modern industry flange by dielectric corrosion, wash away, temperature, pressure, the factors such as vibrations are influenced,
Due to the error of sealing surface processing dimension, the reasons such as the aging of sealing element and installation fastening are improper, and be also possible to because
Moisture in extraneous air causes flange connections that electrochemical corrosion occurs and destroys the compactness of flange connector, unavoidably
The leakage for causing flange.If flange leakage problems cannot be administered in time, under the washing away of medium leakage can be made to expand rapidly,
The loss of material is caused, the destruction of production environment causes enterprise to shut down and stops production, causes huge economic loss.It is if toxic
Harmful, inflammable and explosive dielectric leakage, it is also possible to cause the major accidents such as personnel's poisoning, fire explosion.
The content of the invention
For the problems of the prior art, the present invention provides a kind of vacuum protection formula flange connectors, enable to
It installs between flange and more fastens, avoid flange electrochemistry flange is corroded and slowed down be subject to rainwater and dust and be subject to
Electrochemistry pollution.
The technical solution adopted by the present invention to solve the technical problems is：A kind of vacuum protection formula flange connector, including
Upper flange, lower flange, sealing ring, link block and protective device.
The upper flange is provided with the No.1 upper flange and No. two upper flanges of annular；The No.1 upper flange is provided with
Six bolt holes, the No.1 upper flange periphery are provided with No.1 external screw thread；No. two upper flanges are located in No.1

Six bolt holes, the No.1 lower flange periphery are provided with two extra screw threads；No. two lower flanges are located under No.1
Below flange；
The upper flange is connected with lower flange by six roots of sensation bolt, and sealing is equipped between upper flange and lower flange
Circle, the sealing ring are rubber material；
The link block is annular, and the link block inner wall is provided with internal thread, the internal thread can respectively with
No.1 external screw thread and two extra screw threads are meshed.
During work, first link block with lower flange can be threadedly coupled, then upper flange is threadedly coupled with link block, and on
Flange is bolted with lower flange, and sealing ring is between upper flange and lower flange, and such design is so that upper flange and laxative remedy
It connects between orchid and more fastens.
The protective device includes protective cover, the cyclic spring rubber base positioned at protective cover upper and lower ends and sealing
Pad；
The protective cover is rubber material, and protective cover is hollow revolving body, and the protective cover side is provided with air-breathing
Mouthful, vent plug is installed at air entry；The rubber base includes the seat of honour and lower seat, and the seat of honour is mutually solid with protective cover upper end
Even, the lower seat is fixedly connected with protective cover lower end；The seat of honour is removably bolted on No. two upper flanges, described
Lower seat be removably bolted on No. two lower flanges；Between the seat of honour and No. two upper flanges and lower seat and No. two
Gasket is mounted between lower flange；Before upper flange and lower flange are not connected with, protective cover upper end can be consolidated by the seat of honour
It is scheduled on upper flange, after upper flange is connected with lower flange, then protective cover lower end is fixed on lower flange by lower seat,
So as to which protective cover can be good at protecting flange connector, meanwhile, it can will be between protective cover and flange connector by air entry
Cavity in air suction out so that be approximately vacuum environment in protective cover, so as to slow down the electrochemistry of flange connector pollution.
The beneficial effects of the invention are as follows：
