Perforation, bolt are close to two flanges, your beautiful writings liner sealing.
Flange point is threadedly coupled flange, welded flange and clip flange.Flange all uses in pairs, and low pressure pipeline can be with
Use silk acting flange, the use welded flange of four kilograms of pressure above.Gasket is added between two panels ring flange, then uses bolt
Fastening.The flange thickness of different pressures is different, and the bolt that they are used is also different.Water pump and valve, when being connected with pipeline, this
The part of a little equipment facilities, is also made corresponding flange shape, also referred to as flanged joint.It is all to be used in two planar perimeters
It is bolted while closed union piece, generally referred to as " flange ", such as the connection of ventilation shaft, this kind of parts can claim
For " flange type part ".But this connection is the part of an equipment, it is just bad water pump such as the connection of flange and water pump
It is " flange type part ".More small-sized such as valve can be " flange type part ".
Existing flange is many kinds of, but structure is substantially similar, be all with bolt and screw hole cooperation fastened, but for
Some special devices such as vacuum tank etc. needs strictly to keep leakproofness, and the prior art generally uses cementing or welding manner by method
The gap on blue surface seals, but the method affects the disassembly and secondary use of flange.
Utility model content
The utility model aiming at use in the prior art cementing or welding manner by the gap of flange surface seal with
Keep leakproofness, the technical issues of affecting demounting flange and secondary use provides a kind of vacuum tank with cutting plate flange.
In order to solve the above technical problems, the utility model is achieved by the following technical programs thus: a kind of vacuum tank
With plate flange, including flange main body and sealing rubber ring is cut, the bottom of flange main body passes through the surface of annular slot and sealing rubber ring
It is clamped, is fixedly connected with annular installation set at the top of flange main body, the internal activity of annular installation set is connected with annular steel ring, ring
Elastic hose is fixedly connected at the top of shape steel ring inner surface.
Preferably, the center of annular installation set offers mounting groove, and the surface of mounting groove offers card interface.
Preferably, card interface setting there are four, the top of annular installation set and offered positioned at card interface between bolt pacify
Fill hole.
Preferably, ring type seal is fixedly connected at the top of annular steel ring, the section of annular steel ring is arch.
Preferably, there are two sealing rubber ring settings, the diameter of two sealing rubber rings is different.
Preferably, the inside of sealing rubber ring offers cavity.
Compared with prior art, the utility model have it is following the utility model has the advantages that
(1) the utility model structure is simple, easy to use, utilizes flexible elastic hose, annular steel ring and annular
Sealing ring cooperation, can make air tight between top to connecting pipe and flange main body and the top of annular steel ring, and then guarantee
It is to stable connection between connecting pipe and connected device air tight, it ensure that required vacuum requirement, and do not have to cementing weldering
It connects and is sealed, detachable rear secondary use.
(2) the utility model only needs to match by setting mounting groove and bolt mounting holes, the flange to connecting pipe bottom end
Card interface can be easily installed into annular installation set, not influence installation requirements, and can guarantee connection using annular installation set
It is secured, axial tension suffered by bolt can also be reduced, avoid bolt strained excessive and fracture.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As Figure 1-Figure 4, the utility model provides a kind of vacuum tank with cutting plate flange, including flange main body 1 and sealing
Cushion rubber 2.There are two the settings of sealing rubber ring 2, and the diameter of two sealing rubber rings 2 is different；The inside of sealing rubber ring 2 offers cavity,
