Description
Technical field
The utility model relates to a kind of flanges, more particularly, to a kind of pinching flange.
Background technique
Flange is called ring flange or flange, makes pipe and pipe part interconnected, is connected to pipe end.There is hole on flange
Eye, can wear bolt, typically refer to open the hole of upper several fixations for connecting it on the periphery of the metallic object of a similar plate-like
Its thing.Existing flanged joint is exactly that two pipelines, pipe fitting or equipment are first individually fixed on a ring flange, two
Between a ring flange, in addition flange gasket together with bolt fastening completes connection, due to needing to use during installation
Multiple bolts are installed, therefore are installed, disassembly inconvenience.
Utility model content
The technical problems to be solved in the utility model is the defect for overcoming existing flange dismounting inconvenient, provides a kind of clamping
Type flange, to solve the above problems.
To achieve the above object, the utility model provides the following technical solutions：A kind of pinching flange, including ring flange,
Flange gasket and clamping device, the clamping device by the collar of two semicircular clevis with form, two described semicircle clamping ring one end
Hingedly, two semicircle clamping ring other ends are bolted, and set that there are two semicircles inside the semicircle clamping ring
Shape slot, the ring flange includes two and structure is identical.
As a kind of optimal technical scheme of the utility model, the bolt is wing bolt.
As a kind of optimal technical scheme of the utility model, the flange gasket is asbestos or rubber material.
As a kind of optimal technical scheme of the utility model, the section of the semi-circular groove is right-angled trapezium.
Compared with prior art, the utility model has the beneficial effects that：This kind of pinching flange can be incited somebody to action by clamping device
Two ring flanges are clamped by bolt, and convenient for disassembly and assembly, structure is simple, can promote the use of.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings：
Fig. 1 is a kind of pinching flange arrangement schematic diagram described in the utility model；
Fig. 2 is a kind of pinching flange sectional view described in the utility model；
In figure：1, ring flange；2, flange gasket；3, semicircle clamping ring；4, bolt；5, semi-circular groove.
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.
The utility model provides a kind of technical solution referring to FIG. 1-2,：A kind of pinching flange, including ring flange 1, method
Blue pad 2 and clamping device, clamping device by two semicircular clevis collar 3 with form, two semicircle 3 one end of clamping ring are hinged, two
A semicircle 3 other end of clamping ring is connected by bolt 4, two ring flanges 1 can be clipped in two semicircular clevis collar 3 by bolt 4
Between, the connection of two ring flanges 1 can be realized, it is convenient for disassembly and assembly, it is set inside semicircle clamping ring 3 there are two semi-circular groove 5, semicircle
Shape slot 5 can be used to mounting flange 1, and ring flange 1 includes two and structure is identical.
Bolt 4 is wing bolt, and wing bolt disassembly is easy for installation, and flange gasket 2 is asbestos or rubber material, flange gasket 2
It can be used to seal the junction of two ring flanges 1, the section of semi-circular groove 5 is right-angled trapezium, makes two flanges in the process of clamping
Disk 1 connect even closer with flange gasket 2.
Concrete principle：In use, two connecting tubes are separately mounted on two ring flanges 1, a ring flange 1 is put into one
In a semi-annular slot, flange gasket 2 is then close to 1 inside of ring flange, another ring flange 1 is put into another semi-circular groove
In 5, two ring flanges 1 are clamped by bolt 4 with flange gasket 2, can will realize the sealed connection of two ring flanges 1.
This kind of pinching flange can be clamped two ring flanges by bolt by clamping device, convenient for disassembly and assembly, structure letter
It is single, it can promote the use of.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
