Description
Technical field
The present invention relates to a kind of flange, more particularly to a kind of accurate mechanical connection flange.
Background technology
In the connected mode of mechanical part, common use flange builds connection, and common flange can only play a part of connection, after sealing effectiveness is all bad, but flange is connected with pipeline, the liquid substance of flowing will overflow from the junction of flange in pipeline, leakage is caused, normal work is influenceed.In the prior art, for media such as Seal Oil, gas or water, in the junction such as pipe joint or plunger of pipeline, gasket seal can be used mostly, existing gasket seal is mostly using gum pad, asbestos pad etc., sealing effectiveness is poor, and assembling is complicated, easily comes off, connection is very inconvenient, the set-up time is wasted, connection speed is reduced, and increased the labour intensity of operator.
The content of the invention
The purpose of the present invention is that a kind of easy to operate, good sealing effect of offer, accurate mechanical connection flange difficult for drop-off.
To achieve these goals, the technical solution adopted by the present invention is such：Accurate mechanical connection flange of the invention, including flange body, flange body middle part is provided with connecting hole, screwed hole is provided with flange body around through hole, the flange body upper surface middle part is provided with boss, through hole is provided with boss, the internal diameter of through hole forms stepped hole more than the internal diameter of connecting hole, sealing device is provided with the step of stepped hole, sealing device includes the metallic framework of annular, the upper and lower surface of metallic framework is provided with sealant, metallic framework inwall is provided with sealing gasket, the upper surface of sealing gasket is provided with the projection of two arcs, the groove of an annular is provided with around flange body lower surface through hole, sealing ring is provided with groove.
Preferably, the flange body outer wall opposite sides is respectively arranged with lug.
Preferably, the lug and boss are integrally formed with flange body.
Preferably, the sealing device is bonded in through hole.
Compared with prior art, the advantage of the invention is that：The present invention is rational in infrastructure, and easy to operate, adhering and sealing device in flange, good sealing effect, sealing device is difficult for drop-off, extends its service life.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1,Accurate mechanical connection flange of the invention,Including flange body 1,The middle part of flange body 1 is provided with connecting hole,Screwed hole 7 is provided with flange body 1 around through hole,The upper surface middle part of the flange body 1 is provided with boss 2,Through hole is provided with boss 2,The internal diameter of through hole forms stepped hole 3 more than the internal diameter of connecting hole,Sealing device is provided with the step of stepped hole 3,Sealing device includes the metallic framework 4 of annular,The upper and lower surface of metallic framework 4 is provided with sealant 5,The inwall of metallic framework 4 is provided with sealing gasket 6,The upper surface of sealing gasket 6 is provided with the projection of two arcs,The groove of an annular is provided with around the lower surface through hole of flange body 1,Sealing ring 8 is provided with groove,The outer wall opposite sides of the flange body 1 is respectively arranged with lug 9,The lug 9 and boss 2 are integrally formed with flange body 1,The sealing device is bonded in through hole.
When using, one end of the connector of connection will be directly needed to be arranged in the stepped hole 3 of flange, then by two flange through hole bolt connections；Adhering and sealing device in flange, good sealing effect, sealing device is difficult for drop-off,；Metallic framework 4 is provided with sealing device, some strength is made it have, its service life is extended, lug 9 is set in flange body 1, it is convenient to install；The lower surface of flange body 1 is provided with sealing ring 8, the sealing of enhancing two flanges connection.
