Description
Technical field
A kind of attachment means are the utility model is related to, especially a kind of multiple spot inlet seal flange.
Background technology
It is well-known：Flange connection is widely used in the connection between pipeline, can be easy to by flange connection
The installation and replacing of pipeline.Existing flange connecting apparatus, only there is the function of connection.
Therefore when needing the pipeline for being passed through gas to be attached some, air inlet function, existing technology can not be realized
Means are by setting passage on pipeline, so as to realize ventilation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of multiple spot air inlet that can be realized and be ventilated into pipeline
Sealing flange.
Technical scheme is used by the utility model solves its technical problem：The utility model provides one kind and clicked through more
Hermetic seal flange, including inner flange, outward flange；The inner flange has annular boss, is provided with the outward flange and interior method
The groove that annular boss matches on orchid, the outward flange are sleeved on annular boss；The annular boss upper end be provided with outside
The sealing ring of the inner ring matching of flange upper groove, the annular boss hold out against sealing ring in groove；Set on the inner flange
At least three vent lines that inner flange inner ring is extended through by the second flange exterior surface are equipped with, the vent line is in inner flange
Circumferentially it is uniformly distributed on inner ring.
Further, the outward flange with flange and inner flange with the second flange between be provided with sealing gasket.
Preferably, the vent line has four.
Preferably, the sealing ring uses rubber ring.
The beneficial effects of the utility model are：Multiple spot inlet seal flange described in the utility model is due to including inner flange
And outward flange, and sealing ring is provided between inner flange and outward flange, therefore pass through inner flange crush seal circle, Neng Goushi
Existing clearance seal between flange and pipeline, while be provided with least three on inner flange and extended through by the second flange exterior surface
The vent line of inner flange inner ring, the vent line are circumferentially uniformly distributed on the inner ring of inner flange, therefore can be realized
The air inlet of pipeline；So as to avoid that air admission hole is set on pipeline, the manufacturing process for needing admission line can be simplified；It is easy to simultaneously
The sealing and replacing of pipeline.

Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figures 1 to 4, multiple spot inlet seal flange described in the utility model, including inner flange 1, outward flange 2；
The inner flange 1 has annular boss 12, be provided with the outward flange 2 with the groove that annular boss 12 matches on inner flange 1,
The outward flange 2 is sleeved on annular boss 12, and the upper end of annular boss 12 is provided with the inner ring with the upper groove of outward flange 2
The sealing ring 3 matched somebody with somebody, the annular boss 12 hold out against sealing ring 3 in groove；Be provided with the inner flange 1 at least three by
The outer surface of second flange 13 extends through the vent line 11 of the inner ring of inner flange 1, and the vent line 11 is on the inner ring of inner flange 1
Circumferentially it is uniformly distributed.
Sealing ring 3 is held out against and can be accomplished in several ways in groove by the annular boss 12, specifically, the ring
Shape boss 12 with height and the thickness sum of sealing ring 3 be more than or equal to groove with depth, the thickness of the sealing ring 3
Degree is when to refer to sealing ring 3 be flat annulus, the thickness at the flat position of sealing ring；When sealing ring 3 is the annular that cylinder surrounds,
Sealing ring cross section on roundlet the thickness of a diameter of sealing ring 3.
As shown in figure 5, first outward flange 2 is sleeved on pipeline 5 during use, then by the set of tubes 5 of sealing ring 3
On, inner flange 1 is finally enclosed on the outward flange of pipeline 5 again.By the way that outward flange 2 is pressed on inner flange 1 in the edge of pipeline 5,
So that the crush seal circle 3 of inner flange 1, sealing ring 3 is close to the inwall of connecting pipe 5 by annular boss crimp, with squeezing
Pressure degree increases, and the contact area of sealing ring 3 and connecting pipe 5 increases, between the sealing pipeline of sealing ring 3 and the inner ring of inner flange 1
Gap, and sealing inner flange 1 and the inner ring of outward flange 2 between gap；So that favorable sealing property.
Simultaneously when needing to be passed through gas, extended through by what is set on the inner flange 1 by the outer surface of the second flange 13
The vent line 11 of the inner ring of inner flange 1, is passed through gas, and gas is entered in pipeline 5 by the inner ring of inner flange 1.Due to described logical
Air pipe 11 is circumferentially uniformly distributed on the inner ring of inner flange 1, therefore the air-flow that can be passed through in pipeline 5 is uniformly distributed.
In summary, multiple spot inlet seal flange described in the utility model is due to including inner flange and outward flange, and
Be provided with sealing ring 3 between inner flange 1 and outward flange 2, therefore by the crush seal circle 3 of inner flange 1, can realize flange with
Clearance seal between pipeline, while be provided with least three on inner flange 1 and inner flange is extended through by the second flange exterior surface
The vent line 11 of inner ring, the vent line 11 is circumferentially uniformly distributed on the inner ring of inner flange, therefore can realize pipe
The air inlet in road；So as to avoid that air admission hole is set on pipeline, the manufacturing process for needing admission line can be simplified；It is easy to pipe simultaneously
The sealing and replacing in road.
In order to ensure the seal between the flange 21 of outward flange 2 and the second flange 13 of inner flange 1, further, institute
State outward flange 2 with flange 21 and inner flange with the second flange 13 between be provided with sealing gasket 4.
In order to ensure that the air-flow in pipeline in all directions is uniform, it is preferred that the vent line 11 has four.Pass through
Four vent lines 11 are set, air inlet while so as to realize on " ten " word four direction, the gas in pipeline can be ensured
Stream is uniform.
In order to reduce cost, extend the service life of sealing ring 3, it is preferred that the sealing ring 3 uses rubber ring.
