Description
Technical field
The utility model is related to field of stents more particularly to a kind of ring flanges.
Background technology
Ring flange is called flange flange disk or flange.Ring flange is the part being connected with each other between pipeline and pipeline, usually
For the connection between pipe end；Also have with the ring flange imported and exported in equipment, for the connection between two equipment, such as
Speed reducer ring flange.
Ring flange of the prior art is typically directly to have sealing ring in upper flange or lower flange end set, these sealings
Easy aging after fluid is wanted in circle contact, and the sealing effect for leading to ring flange is poor, meanwhile, upper flange and lower flange are connected by bolt
Due to pipeline, there is shakings after connecing, and lead to ring flange there are circular runout, so as to cause security risk.
Therefore, the prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of ring flanges, it is intended to solve existing
There is the difference of the flangeseal effect in technology and there are problems that circular runout.
The technical solution of the utility model is as follows：
A kind of ring flange, wherein, the ring flange includes:
It is mutually adapted the discoidal upper flange ontology of installation and lower flange ontology, the upper flange ontology and lower flange sheet
The through-hole for connecting pipe is all provided in the middle part of body；
The upper flange ontology periphery is provided with annular groove, and the lower flange ontology periphery is provided with recessed with the annular
The annular protrusion that slot is adapted；
The annular protrusion madial wall is provided with annular seal groove, and the annular seal groove is equipped with sealing ring.
Preferably, the ring flange, wherein, the upper flange ontology and lower flange ontology are all provided with to install spiral shell
The mounting hole of bolt.
Preferably, the ring flange, wherein, the sealing ring is teflin ring.
Compared with prior art, ring flange provided by the utility model, including：Be mutually adapted installation it is discoidal on
It is all provided in the middle part of flange body and lower flange ontology, the upper flange ontology and lower flange ontology for the logical of connecting pipe
Hole；The upper flange ontology periphery is provided with annular groove, and the lower flange ontology periphery is provided with and the annular groove phase
The annular protrusion of adaptation；The annular protrusion madial wall is provided with annular seal groove, and the annular seal groove is equipped with sealing ring,
So that the sealing effect of the ring flange is good, meanwhile, the circular runout after avoiding upper flange and lower flange installation is complete.
Description of the drawings
Fig. 1 is the structure diagram of the ring flange preferred embodiment in the utility model.
Specific embodiment
The utility model provides a kind of ring flange, for make the purpose of this utility model, technical solution and effect it is clearer,
Clearly, referring to the drawings and give an actual example to the utility model be further described.It is it should be appreciated that described herein specific
Embodiment is only used to explain the utility model, is not used to limit the utility model.
Fig. 1 is the structure diagram of the ring flange preferred embodiment in the utility model, as shown in Figure 1, the utility model
In a kind of ring flange that preferred embodiment provides, the ring flange includes:It is mutually adapted the discoidal upper flange ontology of installation
100 and lower flange ontology 200, the upper flange ontology 100 and 200 middle part of lower flange ontology are all provided with for connecting pipe
Through-hole；100 periphery of upper flange ontology is provided with annular groove 101,200 periphery of lower flange ontology be provided with it is described
The annular protrusion 201 that annular groove 101 is adapted；201 madial wall of annular protrusion is provided with annular seal groove（Do not show in figure
Go out）, the annular seal groove is equipped with sealing ring.
When it is implemented, the upper flange ontology 100 and lower flange ontology 200 are respectively welded at the pipeline to be connected
End, the movement of the annular protrusion 201 of lower flange ontology 200 is fitted in the annular groove 101 of upper flange ontology 100, is made
Improve flangeseal in advance under, eliminate radial direction between upper flange ontology 100 and lower flange ontology 200 and jump
It is dynamic.
In the further preferred embodiment of the utility model, the upper flange ontology 100 and lower flange ontology 200 are all provided with
For the mounting hole of installation bolt（It is not shown in figure）.
In the further preferred embodiment of the utility model, the sealing ring is teflin ring.
The ring flange that the utility model preferred embodiment is provided can be used for connecting the pipeline of various media.
In conclusion ring flange provided by the utility model, including：It is mutually adapted the discoidal upper flange sheet of installation
The through-hole for connecting pipe is all provided in the middle part of body and lower flange ontology, the upper flange ontology and lower flange ontology；It is described
Upper flange ontology periphery is provided with annular groove, and the lower flange ontology periphery is provided with the ring being adapted with the annular groove
Shape protrusion；The annular protrusion madial wall is provided with annular seal groove, and the annular seal groove is equipped with sealing ring so that described
The sealing effect of ring flange is good, meanwhile, the circular runout after avoiding upper flange and lower flange installation is complete.
It should be understood that the application of the utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
It says, can be improved or converted according to the above description, all these modifications and variations should all belong to the appended power of the utility model
The protection domain of profit requirement.
